Turbo 3.8L Cayman Engine Build (Porsche M96) - Part 1

[@gnrrpreacher]

I think the Cayman is what brought me to your channel. I look forward to the fix and the hp gains.

[@BoostBrothersGarage]

Thanks! It’s going to be a fun one!

[@frankleonard5908]

Great news, glad to here more about the cayman, I guess my next boxster will be the 987.2 engine, Thanks.

[@BoostBrothersGarage]

They demand a premium, but the peace of mind would be worth it to me

[@joolzb17471]

I read that the 997/987.2 engines go south as well - there’s a laundry list of failure modes. The only ones that are bullet proof are the turbo and GT3 cars using the Mezger block and the newer non M9 engines.

[@BikerBloke600]

Exciting times ahead. Looking forward to it ,👍

[@BoostBrothersGarage]

Thanks Michael, us too!

[@EdPrscheTurbo]

Sounds great good luck guys can’t wait to see the build videos

[@BoostBrothersGarage]

Thanks, much appreciated! Hopefully we can get some more parts in soon so we can get after it

[@kylekloewer951]

Oooooh yeah baby!!!! Now this is going to be next level!

[@kylekloewer951]

Also, if you need parts directly from Porsche, try sunsetporscheparts.com. We don’t have sales tax so we sell a lot of parts through our site!

[@BoostBrothersGarage]

Awesome, thanks dude!

[@BoostBrothersGarage]

It’s gonna be something, an unreliable mess probably haha

[@kylekloewer951]

Haha true, but damn fun when it’s makin boost!

[@BoostBrothersGarage]

As long as it stays alive

[@artmchugh5644]

Mike the 914 is friggin nice !!😄😄

[@BoostBrothersGarage]

Thanks! Super generous of Thomas, I’m really excited about it!

[@rodgerq]

This should be interesting and those pistons are an actual work of art!

[@BoostBrothersGarage]

Thanks! Definitely excited to see it come together

[@mister9643]

YASSSS! So excited for this project. The cayman is what got me hooked on your channel. I’m taking notes for when our 987.1 pops 😅 Good work on the M3 btw, that was a smokin deal!

[@BoostBrothersGarage]

Haha, hopefully yours lasts longer than ours did. If not, here’s your roadmap!

[@keithryan9314]

You can get the e46's cheap enough here too but that's because the government rape us on annual road tax 😒

[@BoostBrothersGarage]

Ha, why is government always trying to keep us from having nice things?

[@DWraysGarage]

Wow - you guys have content for some time on this front - never mind your other projects. This is a channel to watch folks! Gonna have to birth that boy of yours in the garage, Mike! Get the crib setup in there now!😆

[@BoostBrothersGarage]

Ha, all the potential content and no time or money! If my wife would let me I'd have him at the shop from day one haha. Not sure how else I am going to get to sneak away for the first few months? How's the car now that the plenum and exhaust are done?

[@DWraysGarage]

Check out today's release and you'll be all caught up. kzbin.info/www/bejne/el6ZoYygr519bNk. Might as well get him hooked on the intoxicating melange of Miller Lite, Engine Oil, Grease, Gas and BO early! May need some earmuffs for when uncle Zach is within earshot 😲!

[@BoostBrothersGarage]

Awesome, will do!

[@IamCredit]

Sick update guys! The Cayman is gonna be a f*cking monster. On the upside, since it's late July you guys can take your time with the build and just shoot for a spring completion date.

[@BoostBrothersGarage]

Thanks dude! That's the goal, as long as we don't hit any major snags... How's you car doing, still running good?

[@IamCredit]

Yeah, my 3.8L is still kicking ass. Just did a wet Autobahn South last week. Still trying to get myself out to Gingerman and a dry Autobahn this year.

[@dirtriderz6881]

You guys should have way more subscribers. Great work! I hope you keep it up!

[@BoostBrothersGarage]

Thanks, much appreciated!!!

[@tradesman1000]

Nice boys! 👍🏻 man that’s going to be a GT3 RS killer! GT2 RS even 😳😀 mid mounted as well. Wow! Can’t wait to see it come to fruition.

[@BoostBrothersGarage]

Thanks! It’s going to be a riot when it’s done. Just a whole lot of trial and error to get it there. Going to be a fun build!

[@tradesman1000]

I’m working hard on just getting my Cayman S and have plenty of ideas for mods and cosmetic improvements. Iv already purchased a lot of performance parts to fit it. Just have to get the car now! 😁

[@BoostBrothersGarage]

Do it, you won’t regret it!

[@keomo]

I'm excited for you guys as well! I just had an engine failure on my 987.1 Base Cayman... snapped timing chain on bank 1 and this happened only 4 months and 1600 miles after I bought it. PIWIS read out confirms that the car was never abused (only range 1s, no range 2,3,4 and 5). I'm on the fence as to what I want to do with it. Can't wait to see how your build turns out :) Thanks for sharing.

[@BoostBrothersGarage]

Thanks Kevin. Sorry to hear about your car. What options are you weighing?

[@keomo]

Dudes... that's like the killer question. I'm sure you've been through all of the options yourselves... going from selling it as a roller, swapping for the same engine, rebuild, oversize, 911 swap, turbo, etc... Man, can't be more on the fence right now. I have no clue!! But I will keep you posted! I feel you both on the situation with the 987.1. Also, I have a 996TT which is stock, so modding the 987.1 is pretty tempting!

[@BoostBrothersGarage]

Hell yeah, with the 996 in the garage you should go all out on the 987! What do you want to do with the car? I rode in an LS swapped Boxter and it was a blast. Really weird to feel one of these cars with that much torque. It was stupid fast. Vision can build you a bulletproof 3.8, but without a turbo you won’t see more than 350 whp if I had to guess. The turbo build is going to be a lot of fun. There are some major issues we will need to work through, but that’s what will make it so awesome in the end. Lastly, for the lowest invest, you can find used 987 base engines for a somewhat reasonable amount. We also considered just buying a salvage 987.2 and swapping the guts and parting the rest out. Not to confuse you any more haha.

[@keomo]

I've never had a track car, so that could be an itch I could scratch with the 987. Going that route would have me focus on engine durability/reliability, suspension, brakes, LSD and stripped interior. But I am also attracted in building something like a mini Singer/Ruf car which would rather focus on a bump in performance, LSD, nice sounding exhaust, wheels, aftermarket GT style wing, half roll cage, clear engine cover and classy interior. So many choices!!

[@BoostBrothersGarage]

Both sound like great options! For a track car, I would consider tracking down a 987.2 engine. For the latter, I would go with a Vision built 3.8L and a turbo!

[@SpooledUpTV]

Run a dual tune! 800 for hooning around and 550 for track! I’m hyped for you guys! This is gonna be a fun car!!

[@BoostBrothersGarage]

Ha, 800 sounds super dangerous, this is no RB!

[@SpooledUpTV]

Boost Brothers Garage sike! It’s a super performance expensive Porsche! 800 is being conservative!

[@BoostBrothersGarage]

Lol, I think it’s made of glass

[@Fred82ndAbn]

Nice! Can you disclose how much was it for block re-sleeving? We need another good option other than LN Engineering. Charles is excellent but competition is always good for paying customers. Great vid!

[@BoostBrothersGarage]

Thanks! We actually bought the block sleeved so I don’t know the cost. You can check with Vision Motorsports, they did our crank work and inspected the block.

[@AudreyH48]

Nice! This car is going to be wicked! Don't forget to be upgrading brakes and suspension to keep it straight-ish! Oh yeah, weren't you considering widebody? #hype haha

[@BoostBrothersGarage]

If it turns out to be half of what we think it will, it should be pretty awesome. Widebody was a possibility but Zach just got stock width BBS E88’s and I think that means it will stay stock

[@artmchugh5644]

Boost Brothers Garage any plans for the stock Cayman brakes ? I think they may fit our 85 carrera .

[@scottywong]

I am a winner!!! Lol thanks guys

[@BoostBrothersGarage]

Winner winner chicken dinner! Shoot us an email at [e-mail] with your shipping info and we’ll send it your way!

[@joolzb17471]

Hi guys - great channel and loved the Cayman mods before it went pop - I was following you almost mod for mod. (IPD/GT3TB - Cat less Headers etc,) Currently working on my own rebuild that I picked up - 997 3.8 C2 with a destroyed engine, so I’m keen to hear some of your decisions regarding crank case/ cylinders./ pistons and the crank itself... What did Vision do to improve the crankshaft - was it the GT/Cup Motorsport chamfered oil holes? Or did they do more - love to know. When you say the bores are sleeved what did you go for? Nikasil or Ductile Iron? Which is better for the turbo application? Also, did you close the deck with the sleeving for added cylinder support? I guess you will run the lower temp thermostat, any thoughts about Evans Power Cool 180 coolants? On Pistons - are the JE pistons coated on the sides / top? Are you doing any gasflow polishing and porting to the heads at all? Any thought on valve spring choices? Do you need any frequency dampers on the crank side when running a solid flywheel - I’m told the solid flywheel could damage the crank if the setup isn’t perfect.

[@MrJustinhi]

oh yes!

[@MrJustinhi]

987.1 when it bangs ill go for 3.6 ...

[@lesmurray2000]

You've got a big challenge ahead. You're fitting a 5-chain engine into a 3-chain car. DME tuning will be interesting. Glad to see you moving ahead with this. My 3.8 is doing well and trying to save up for the next round of mods. For an intake - look for a 996 X-51 manifold. Seems to be the best fitting option. Your plastic 987 manifold won't work. Also, you'll probably want to use your Cayman injectors. I had to upgrade mine to get enough fuel. I was leaning out at 4500 RPMs.

[@BoostBrothersGarage]

We will be running full stand alone engine management to get around these issues. Glad to hear it's doing well! What mods are next? Good call on the X51 intake, that should save us a ton of time and energy!

[@lesmurray2000]

Several things planned - Numeric Shifter cables are next, thinking about the Numeric shifter as well $$$. Then will upgrade the intake system - IPD Competition Plenum, GT3 Throttle Body, X51 intake. I already bought an EVOMS intake filter. I also have a GT3-style rear bumper to put on and want to get a matching front bumper as well. My jindie wants me to swap headlights to 997 style, but big bucks for bi-xenons.

[@BoostBrothersGarage]

All solid mods. I feel like the shifter mods are a MUST!

[@keithryan9314]

l love dirty updates :))

[@BoostBrothersGarage]

Don’t we all!

[@keithryan9314]

Boost Brothers Garage this will be a cool build series looking forward to it 👍

[@Praveen_ps_Kumar]

Hey guys! Awesome channel! Started watching a video from you guys yesterday as I have been planning to buy a 2008 Cayman S. Very interesting videos. Kudos to you all for putting in a lot of amazing content out there. Will be very educational. You made me think now if I have to really go ahead with my idea on buying the 2008 Cayman S. Thoughts?

[@BoostBrothersGarage]

Thanks for the kind words! What are your plans with the car (street, track, both)? If you don’t mind me asking, what is your budget?

[@Praveen_ps_Kumar]

Boost Brothers Garage absolutely. Budget would be 25k. It would be a fun weekend project car. I would be looking to also use it in the track maybe 5 times a year to the max.

[@BoostBrothersGarage]

25k will limit you to a 987.1. Now, there are horror stories all over the internet, and we obviously had issues... BUT, there are a ton of people tracking these cars with no issues, we see them all the time in our local PCA. Also, Porsche just came out with a program that is offering the M96/M97 crate engines for MUCH cheaper than the aftermarket has offered in the past. It really is a great car, and I’d hate to see someone stay away because of what MIGHT happen. If it was me, I would shop around and find one for 22-23 and use the extra room in your budget to do a deep sump / baffled pan. With that, good oil, and keeping it off the rev limiter (I.E. not bouncing it off the limiter doing donuts like us) and you should be fine!

[@Praveen_ps_Kumar]

Boost Brothers Garage Great. Thanks for your advise. Will do as per your suggestion. Let me know if you have any other thoughts. Will stay by your side as you get your Cayman up and running

[@BoostBrothersGarage]

Thanks! If you need any advice on what mods to do, what order to do them in etc, just let us know! We always do our best to respond to all the comments here.

[@alltimeproductions3749]

Whatever happened to your 951 build?

[@BoostBrothersGarage]

The 951 itself is going to the scrapper. But, the widebody car that is getting the 951 drivetrain is still going. It got pushed to the back burner while we were getting the GTI and 944 ready for track season, but I am getting ready to jump back on it.

[@DirtDude117]

Makes me wish I didn't get a 987.1 the more I see videos about built engines. Really waiting on someone to figure out the wiring harness for the LS swap. I have a LS3 from a 2010 Camaro ready to go & my 987 has a Boxter S engine so it does not have a coolant level sensor or Exhaust Valve Solinoids (P0084 & P0078). Mine's still drivable but it's annoying having these codes come on. If you guys decide you want a different chassis let me know!

[@BoostBrothersGarage]

The LS swap has its own inherent issues as well. Make sure you research it. With that being said, when we were considering the LS, we were just going to go stand-alone engine management. It just makes more sense with a build like that.

[@mikedodd9294]

Swap in a Tesla motor, its tiny, no transmission, scrap the emissions, exhaust, cooling. Once done with batteries it will weigh the same but have LS3 smoking torque

[@TheTexasOiler]

Cayman video yeah, wait hold up you guys giving prizes now wth I want to get a prize...

[@BoostBrothersGarage]

Hahaha, you should have guessed the price on the last video! Hopefully sometime in the near future we can get something cool from a vendor and do a REAL giveaway.

[@CincySupercar]

550 wheel cayman?!?! (Heavy breathing)

[@BoostBrothersGarage]

Haha, not sure if it’s going to be really fast, really scary, or both

[@gregschlegel5964]

Not to be negative but it appears you have bitten off more than you can chew

[@BoostBrothersGarage]

That’s fair, but I disagree. There are going to be some major challenges, but we will work through them

[@scousepie2]

Talk Talk Talk..lol

[@BoostBrothersGarage]

Haha, I know... If we had all our parts it would be build build build. Felt like an update was in order for our subscribers. Sorry if it was boring!

[@e36s54]

More building, less talking

[@BoostBrothersGarage]

Ha, agreed, and yet we can’t because we don’t have everything we need
