When this is done, it'll be the nicest VR4 in the country.

[@TomsTurboGarage]

Thank you for saying that! I'm glad you feel that way, although I know there are a bunch out there that are much nicer and done very well. Mine will likely be the most confusingly stock appearing one though. Haha!

[@devinandjim]

Tom I really appreciate that you’re a good wholesome hearhead. Your dorky humor is fun and entertaining. I’m glad to see there are other people out there that aren’t just going “full send” on everything they do and there are people like you and I that know how to make a tasteful build. Thank you keep up the good work buddy.

[@PKudu]

I'm not sure what I like the most, the quality of the videos, the quality of the work, or the cleanliness of the work area.

[@TomsTurboGarage]

Thank you for the kind words man and I'm glad you enjoy the videos!

[@ItchiusScrotus]

You follow the best procedures to a reliable build, every step I think you are going to miss you cover just minutes later! I really like how you pay attention to the interior and exterior being stock and complete with the best second hand parts you can find if new genuine parts are not available. My favourite things are the you keep everything as stock looking as possible and gratuitous use of torque specs, I know I can't sleep unless I know my builds are correctly torqued! Keep the vids of this build flowing!

[@TomsTurboGarage]

Thank you for the very kind words! It sounds like we share a brain on this sort of thing and like our cars built the same way. Stay tuned, lots of cool stuff on the way!

[@tonkatoytruck]

I can tell you are having more fun than we are and that we are all happy to just be along for the ride. Had a great day and this video was just icing on the cake. Thanks for the video and subscribing.

[@TomsTurboGarage]

Thanks man, I'm glad you feel that way!

[@edsnarf2431]

You should reconsider using the gasket as the guide to your porting. Often a gasket is intentionally sized so that its inner opening diameter is larger than the mating pieces. This keeps the edge of the gasket away from the roasting hot gases flying by. Exhaust gaskets often have a heat resistant material edged by a soft, white metal. That soft edge isn't nearly as tough as the cast iron and it can be melted. When the joint is tightened it's that metal edge that is compressed and forms the seal. If the inner edge of the seal is burned away the joint is compromised. Opening the joint to the size of the gasket can also create disruptions to the flow. Picture you have two parts that are already correctly matched and the flow between them is uniform, but the gasket is larger. This creates a very slim, shallow gap between the parts, but it hardly changes flow at all. But grinding the inside diameters of the parts to match the gasket will actually create a disruption in the flow. I have always used thin cardboard (think cereal box) to perform porting. Make a gasket without the port holes. Then apply water-based paint, machinists blue, graphite... on both surfaces and bolt them together. When you separate the halves, you'll have the perfect shape of both ports on either side of the "gasket". Now cut the ports in the gasket to the size of the largest port. (That could be either side at any point around the port.) Port to match. If you want to open the port up for better flow do that to one side first, then do the cardboard gasket trick to match the other part. Keep in mind that sometimes a slightly larger header flange is good. Anyone remember anti-reversion headers ?

[@josepeixoto3384]

One learns more from your comment than from the sales pitch up there, Lol Great idea; i'd just use thin sheet metal,brass for instance,0.20 to .040;( not that i would *EVER* waste time or money with that shite ,in a place where the speedo limito is around 75 mph!! a proper NON turbo will do perfectly for that,AND have great low end torque).

[@TheTurboDad]

I sent this video to all of my south florida dsm friends so they learn the proper way to not only select a turbo but also prep it for best performance. Good shit Tom!!

[@TomsTurboGarage]

Thank you for doing that Richard! I'm glad you enjoyed the video too.

[@jblifeasitis895]

Wow, detailing the road for better performance. And with the right tools, I LOVE IT!!!!!

[@TomsTurboGarage]

Thanks Joppie!

[@silent_bob_]

Loving this build. Sleepers are my favourites and the more they exceed first impressions the better.

[@djkompressor]

Awesome man... rare to see someone that is so patient with their builds... coming along great!

[@TomsTurboGarage]

Thank you Matthew!

[@YTICOLUV]

Awesome video again! ive always wanted to do similar port work but never had the balls to do it. after seeing this process, it's given me a more positive insight into the process. thanks! keep the videos coming

[@TomsTurboGarage]

Thank you sir and I'm very glad that I could help!

[@nickalasonaka6999]

Inspirational for a young engineer:) thanks Tom!! Will continue watching!❤️

[@christoffer1973]

Love your work. Sad I live in Norway. If I was living in America I would like to see your project live. Love your thinking of details and "while I'm there" thinking.. keep it up friend. Greating from Norway.

[@edsnarf2431]

It's a great video ! I've ported many heads and seen some gains, but I wouldn't have hogged out that wastegate port so much. The wastegate is only flowing when you're overboosting. If the turbo is appropriately sized that shouldn't be so much. The wastegate's flapper valve will only flow so much anyway. Cutting the casting so thin in an area that already highly stressed (glowing !) can only be bad. If the boost gauge doesn't show increasing pressure (higher than the wastegate setting) at higher RPMs you don't have a problem that warrants the increased liability. I'd have just rounded the corners a bit. I don't mean to invalidate the video. It's still a wonderful presentation.

[@christoffer1973]

I did this on my turbo diesel daily driver.. weird so smal job/changes do to the mid range. feels like the engine also go smother... Love your videos and I watching them over and over again...

[@ReeceRamsey]

The new music within the videos is really awesome. You're a man of many talents sir, congrats on the new turbz.

[@TomsTurboGarage]

Thank you Reece!

[@estewar03]

Tom your vids NEVER disappoint, they are all great fun to watch and have some helpful info/tips as well. You are the man, can't wait for more of the turbo action to come.

[@TomsTurboGarage]

Thank you sir and I'm glad you feel that way!

[@ChrisTexas]

Awesome video, I find myself checking my video feed every day for a new Tom's turbo garage video. Keep up the exellent work.

[@TomsTurboGarage]

Thank you Chris, glad you enjoyed it!

[@joshuaabuzaid9258]

Before I sold my STi converted WRX Wagon, I used an FP Green with ZERO issues for 50k miles. Great turbos.

[@SERI0USB33F]

I know this was done years ago, but still.. I've loved sleepers since the days of Ford Cortina Cosworths, even the MK1 Mexico's with 2ltr Pinto Turbo's thrown in for shits and giggles.. lovin this series you've got going on (again I know it's a while back lol) just wanted to show my appreciation of a job well done.

[@mikeydeshon5637]

Can't wait for results! That's a SWEET stock appearing turbo. .with amazing power potential!

[@TomsTurboGarage]

Thank you Mike, I'm interested to see how it'll do too! Keeping everything stock appearing while getting the most out of the setup will definitely be a challenge!

[@tehkeet]

Looking awesome Tom! Building suspense as always. Can't wait to see everything put together

[@TomsTurboGarage]

Thank you Nick!

[@fst4g63t]

Love watching these videos, brings back great memories of my 3 dsm's.

[@TomsTurboGarage]

Thank you Darren!

[@M074503]

Its gonna be a monster sleeper! Can't wait. Great job!

[@edayala9171]

Ive been just going down all your builds love this Your attitude is great !

[@TheBrownbear68]

another great step by step video. keep them coming man. Loving the progress of this street sleeper

[@TomsTurboGarage]

Thank you sir, will do!

[@briholio]

The parts look great! Love the coating, porting and attention to detail!

[@TomsTurboGarage]

Thank you sir! I agree that the ceramic coating came out beautifully.

[@Uzic211]

Not had much time for KZbin lately but this was the one I was looking forward to the most. I mean who doesn't love TURBO's and TOM

[@TomsTurboGarage]

Thanks man, I appreciate it! :-D

[@weiliwu78]

Brings back lots of memories back in college. I used to own a 2008 Eclipse GST. These parts are so familiar!

[@mitsubitchy4155]

.

[@weiliwu78]

My mistake, it was a 1998 GST.

[@junglebeansss]

Such awesome work. I love how methodical and clean the work is!!!

[@TomsTurboGarage]

Thank you Jacob!

[@AZN87DSM]

cant wait to see this thing run with the new set up!

[@TomsTurboGarage]

Thanks Peter, me too!

[@pgrens]

Can't wait to see how this turns out! Thanks again for putting this together!

[@TomsTurboGarage]

Thank you my friend! Heck I'm more interested in what you're working on!

[@pgrens]

Nothing too exciting at the moment, cooling system gremlins on the '92 900 Turbo. Still haven't driven it more than around the block yet!

[@TomsTurboGarage]

P. A. Grens Well good luck and I hope you get that sorted out. See ya

[@G8GTJav]

Good stuff. Really enjoy your informative videos and humor.

[@TomsTurboGarage]

Thanks man, glad to hear it!

[@kamilbubalik1993]

What a great job! All the best from Poland Mr. Tom! :D

[@Tuskanr]

Awwww yeah! Another great episode Tom!

[@TomsTurboGarage]

Thank you Jacob!

[@EfraKrajo]

Excellent man, great work! Very interesting to see how you improve your air contact surfaces!

[@TomsTurboGarage]

Thank you sir!

[@rx7chip]

Great video Tom . I really enjoy watching you work . You show a lot of passion for the hobby. By the way I run a FP68HTA on my 07 WRX it's been excellent for 40 thousand miles and still going what a great product .

[@TomsTurboGarage]

Thank you sir! I appreciate the kind words and I'm glad you enjoy the videos! Thanks also for the info, it's good to know that it's working well for you. You just can't beat a stock frame Mitsu turbo, they're extremely reliable. Have fun with your WRX, I bet it's a blast!

[@kolourblind3124]

I enjoyed this video thoroughly

[@gsx90boost]

Tom is a beast like how he gets into detail

[@TomsTurboGarage]

Thank you Irvin!

[@mooreAveCrew]

I fall in love with your Galant every time I see it! Galant VR4 is my dream car :)

[@TomsTurboGarage]

Thanks man, glad you enjoy it! They are fun cars with a very distinct Japanese character.

[@thisguy092]

Amazing, each and every video gets me amped up being a mitsubishi owner. Keep up the good work!

[@TomsTurboGarage]

Thank you jack, glad to hear it! :-D

[@notfried2004]

That's the exact turbo I plan on using in my next Starion build. Supposed to hit like a s16g, but flow like a 20g. Nifty, man. I really dig the Galant VR4's.

[@TomsTurboGarage]

Russell Loyd Sounds good man, enjoy your Starion!

[@theuppercut]

Yay you haven't left the dsm scene!! Heard u sold it 1g and u thought aww man everyone's quitting but I forgot about your gvr4!! So glad I can watch this now thanks Tom!!

[@TomsTurboGarage]

You're welcome Josh, I'm glad your enjoying the Galant videos! Selling the Talon was bittersweet, but allowed me to focus efforts on the Galant, which is a great car with true Japanese character.

[@jayrunning9883]

Really enjoy watching your videos. Great job keep them coming!

[@TomsTurboGarage]

Thank you Jay!

[@YGSpider]

Another great episode Tom !

[@TomsTurboGarage]

Thank you Justin!

[@Idiots_on_Parade]

[@TomsTurboGarage]

Thank you Adam, glad to hear it! Enjoy your Talon!

[@lilredexptsc]

We love your videos Tom! You should really have your own TV show!!

[@TomsTurboGarage]

Thank you sir, I'm glad you feel that way!

[@JermyCant2]

[@TomsTurboGarage]

Thank you Jeremy!

[@brittonwritespoetry]

Great car bro. Very well executed, painstaking buildup.

[@TomsTurboGarage]

Thank you Britton!

[@TKTmon]

I don't really like fwd biased awd cars, but this thing just looks so good and I can't wait to see the finished product.

[@TomsTurboGarage]

Thanks man!

[@SailingGoonies]

Jafro would NOT approve of that port job. I could not see any reflections in that finish! hahaha, jk. Awesome stuff as always. Can't wait to see you spoolin' like a boss in that sleeper beast.

[@TomsTurboGarage]

Haha, you're right about that! Jafro would've definitely done a more thorough job! Thanks man, lots more to come!

[@DestroyersGarage]

great work, your videos keep getting better.

[@TomsTurboGarage]

Thank you man!

[@kimjungun2755]

I can't wait until the next episode! Keep it up tom i love you!

[@TomsTurboGarage]

Thank you Bolo, hang in there my friend!

[@JohnnySnaps]

Great choice on the 68hta! Far and away my favorite FP turbo! Although you have the newer style fp turbine....lucky!

[@TomsTurboGarage]

Thanks man! I totally agree and I didn't realize there was a newer turbine.

[@BrownMan59]

Can't wait to see the end result.

[@TomsTurboGarage]

Thanks man, me too! :-D

[@mitchweiler3905]

I've been waiting for the goodies to get into your hands. Now, post up the next video, I can't wait another couple weeks, haha!

[@TomsTurboGarage]

Haha, hang in there man!

[@jylp4u]

Awesome video! I've never heard of fp, I'll have to look into them!

[@sht12]

Really god job Tom and really thank you for this nice film

[@TomsTurboGarage]

shartooh sh Thank you sir, I'm glad you enjoyed it!

[@Jacob199801]

Lovin the power curve for the turbo that didn't even come online until 6 grand

[@07wrx530]

Love the videos can't wait see what she runs awsome as always

[@TomsTurboGarage]

Thank you sir!

[@StasRyadinsky]

Hey man, great video! Cant wait for part 2

[@TomsTurboGarage]

Thanks man!

[@wildimpo]

Nice work!

[@MRHUBQc]

Awsome video as always, keep up the good work!!

[@TomsTurboGarage]

Thank you sir, will do!

[@Benjay1975]

absolutely amazing video!!!!

[@TomsTurboGarage]

Thank you!

[@s0lution90]

love your work, very clean and precise keep it up!!

[@TomsTurboGarage]

Thank you!

[@jakobalbrecht1154]

you remind me of them late 90s early 2000s classroom videos we used to watch- nonetheless, i like it... it has car stuffs! lol

[@kirylsykalo7752]

Awesome job man.I learned a lot thx to you. I've got a Galant myself but it's 99 2.5 v6 163 HP not VR4. However I love it. Keep up the good job :)

[@TomsTurboGarage]

Thank you for the very kind words Kiryl! Glad you enjoyed the videos and enjoy your Galant!

[@nickritter1992]

yeeeee ! TOM IS GOIN FOR SOME BIGGER NUMBERS THAN I THOUGHT !

[@TomsTurboGarage]

Haha! I really just want headroom for future plans...you know, in case I want to turn up the old horsepower knob. :-D

[@Mr4Grim]

Tom...really liking the progress so far. Though makes me feel bad I haven't had time to work on my gvr4.

[@TomsTurboGarage]

Thank you sir! I hear ya man, it probably looks like I live in the garage, but I rarely get to work out there. This port work is a good example. I could've spent much, much more time on it, but just don't have the time to spend!

[@joeyvon699]

Love the videos and your work keep it up!

[@TomsTurboGarage]

Thank you sir, will do!

[@rpvilleneuve]

Tom your videos are a true inspiration. I use to think to myself "I'll let the speed shop do my work". After having those same shops rape me and watching your all of your videos I have made a pact with myself to do all my own work(aside from maybe a tranny rebuild lol). I am happy to say I have not sent my 2jzgte gs300 to any mechanics as of yet. I'm having a great time doing the work and it's amazing the amount of money I have been saving. Now I can spend that money I saved on more parts!!!!!!! Keep the great vids comming. Maybe I'll even take the leap and make a Facebook so I can send you some pics of my sexy sleeper. Have a great easter buddy.

[@TomsTurboGarage]

I really appreciate you saying this Ryan! I'm glad that I can help in some way and yes there is huge pride had in doing your own work. Even if it's just changing a set of spark plugs, everyone has to start somewhere and each job gives confidence for the next, bigger one. Thank you for all of the support over the years and have a good one!

[@Mediocre1987]

cars is becoming quite the sleeper. keep it up!!

[@TomsTurboGarage]

Thank you Matthew, you're going to love the stuff coming soon!

[@TheExtremepsi]

Tom, you're the man!

[@TomsTurboGarage]

Thanks man!

[@misaelmartinez4523]

you sir have won my like keep up the great videos👌

[@davidmccleary734]

Come on part 2!!! That coating looks great think I may have hijack your Idea there, keep it up man awesome vids, now jafro has to put a new vid out too!

[@TomsTurboGarage]

Thank you David, glad you enjoyed it! I'm pining for a new Jafro video too! Detective Coating is a great company and their work totally speaks for itself. I love their facebook page as they often post pics of their latest projects.

[@johnwerner6043]

Seriously awesome. I've owned DSMs for 16 years. Love this stuff from you

[@vincentcastellano4072]

Thank you Vincent!

[@Philociraptor]

Tom, I love Turbo Time!

[@TomsTurboGarage]

Haha, it's by far the best time! :-D

[@GobotWars]

So, the store out of Texas, sells.... Turbochargers and Turbocharger Accessories.

[@TomsTurboGarage]

Haha, yes!

[@anewzack78]

+GobotWars I visited them. They're a small shop really but kick ass

[@henrikcarlsen1881]

I going to the dentist tomorrow... He'll be doing same job on a tooth of mine. Good video even though I was biased with a bit discomfort.

[@IanLomas]

love the video and the best actor award goes to you

[@TomsTurboGarage]

Haha, thank you Ian!

[@MrBrown4507]

You make the best videos!!!

[@TomsTurboGarage]

Thank you Jess, glad you feel that way!

[@daves8407]

Keep it up man. looking sweet! =D can wait to see her fly!

[@TomsTurboGarage]

Thanks a ton Dave!

[@Aplixys]

haha i was there that day at norwalk when you played the video of those talons!! sick!

[@dsmandparty1225]

Beautifully chosen Turbo I was hoping you'ld pick that one to be completely honest most people would slap a 16G on it and call it good. I wish I was able to do what you and Jafro are doing. I to love turbo vehicles and I also love DSM's. Watching your guys' videos allows me to kinda see all the same dreams I had all play out. One day maybe I can upload a video of me restorng my 1989/90 Eagle Talon. It needs a lot of work but If I can get the parts and time I'll even go as far as putting the factory emmisions back on so I may experience what it was like to drive it off the showroom floor. My dream car is a bonestock 98 AWD TSi. Keep up the great work amd I am really looking forward to the rest of the videos for the sleeping giant.

[@TomsTurboGarage]

Thank you sir and I greatly appreciate all of the kind words! I wish you the best of luck and enjoy the process of working on and fixing up your cars!

[@TommyboyGTP]

Waiting for the next video will be like waiting for Christmas!

[@TomsTurboGarage]

Haha, thanks man!

[@rodywl]

great work!

[@TomsTurboGarage]

Thanks man!

[@bsfibers]

Wow you have such a nice garage to work in! I wish I had that too, and I'd call it: Tim's Turbo Garage :D

[@TomsTurboGarage]

Thank you for saying that Tim!

[@MikeWardwell1976]

Great Vid!

[@Whatzitmatter]

I just swapped turbos in my Mazdaspeed3 and wish I had watched this first - I have a dremel and should've ported to match my gaskets :( Thanks again for another excellent video, and if my BNR S3 ever needs servicing, I'll be sure to port the EM/Turbo/DP flanges.

[@TomsTurboGarage]

I bet that's a fun setup with the turbo upgrade! Sorry to hear that, I'm sure it'll be fine, but turbos do respond wonderfully to this sort of port matching and flow improvement. Have fun with your MS3!

[@64impalaSSRealMechanic315]

Great channel good keep it up bro

[@TomsTurboGarage]

Thank you sir!

[@vedeler87]

you make the best videos. good job :)

[@brandonwoods3485]

Awesome. Thanks

[@mrolskul]

Oh man, shiny new parts. The stuff dreams are made of.

[@TomsTurboGarage]

Haha, you know it man!

[@mrolskul]

Tom's Turbo Garage I especially like the choice of color coating for the parts. It gives it that OEM look while keeping onlookers unsure as to the originality of the mods (stock vs. modified).

[@TomsTurboGarage]

Mr Ol Skül Thanks man, that was all Justin at Detective Coating. I told him I wanted that OEM look but with ceramic protection and he knocked it out of the park.

[@tylersmallwood1352]

Good stuff very informative im hooked

[@TomsTurboGarage]

Thanks Tyler!

[@cesarleon2470]

sweet lord that turbo looks so nice keep up the good work by the way in a few weeks i´m getting my 2g dsm eclipse gst so i´ll send you a photo

[@TomsTurboGarage]

Thank you Cesar! Good luck with your Eclipse, I'll look forward to the pics!

[@garagekspec4095]

I love all your cars! Especially the dsm and the vr4 . I question why don't you own a 240sx s13 or s14 .. Would be crazy to see what you could do to one of those! Keep up the good work love the work you do on your 4g63's

[@DJGreasemonkey]

Very good video,

[@jasonvogue4487]

I agree beautiful Turbo

[@davidjsherwood]

Well done great video.
