Rear mount twin turbo 370z part 2

We are making grate progress on the build here is how our week went Enjoy!

[@GuyX2013]

The exhaust setup looks clean af

[@GearheadsAutofab]

Thanks man !

[@Tain950]

I’ve never been so excited over a project on KZbin. I own a 370z Nismo and you are inspiring me to follow your lead on this project. I’d like to Turbo my own Z without having to spend 10k for a kit. I also agree with you the simpler the better.

[@Tain950]

[@Nocturnal_Services]

They sell a rear mount turbo kit for like 4-5k

@@austinbrown924 do you have a list of what you went with, i wanna rear mount turbo as well don't feel it would cost more than 3k

[@geeaye64]

Make sure you bring that to Nismo Fiesta in San Antonio, Texas May 3-5 2019 so I can hear it in person. "Mad" Mike Taylor will love it once he see it along with some Japanese folks that will be there.

[@charlesstillwell1985]

The one good thing that would be with that oil pump with it being louder you will be able to tell easier if it stops working. I'm gland to see you guys doing a rear mount turbos. I have been thinking about how to do a turbo on my car as far as I know no one makes a kit for my car. I only plan on going with 1 turbo tho. But your videos are definitely helping me to figure out what I would need to do. Thank you.

[@CheddarWhiz]

A little tip, WD-40 causes rubber to swell and weaken over time. I would suggest using a little water or rubbing alcohol. That way, it still lubes the rubber long enough to slip it in, and then it will evaporate away.

[@theonlym12]

Or just use oil..... no need to use any other liquid to lubricate the stuff other than the lubricating fluid that is going to be running through the line.

[@guuuu666]

I wonder why not use an independent lubrication system, a reservoir, pump, heat exchanger etc... I mean you already running an electrical oil pump. Keeps the oil temps cooler and cleaner on both the engine and turbocharger. Also if there's a leak in any of the systems you can save one, the engine or the turbochargers. Even put an independent monitoring system for turbochargers oil pressure and temperature.

[@07wrxtr1]

I like this idea + easier for us simple folk to install

[@sinformant]

That is a good idea! Only issue would be changing two different oils, not a horrible inconvenience, just one more step everytime you change your oil.

[@carfreak1024]

The reason that it is not done the way you suggested is the oil pump cannot create sufficient pressure on the inlet of the turbo center section. Standard oil pressure in a car at operating temperature and high RPM would be about 60-80 psi depending upon RPM, engine type etc. there is no way that that "scavenge" pump can create that pressure. its kind of the reason all oil pumps on engines are gear driven off of the crank so they have enough torque to pressurize the oil. @@sinformant

[@carfreak1024]

also no oil sump on turbos probably not gonna drain well.

[@sinformant]

@@carfreak1024 the oil pump is on the drain side of the turbo

[@josemartinez-dd4yg]

Wastegate dump tubes should come out the center with a shape that fits the bumper.....would look SICK! Also, add skid plates for oil pump to protect it from road debris.

[@GearheadsAutofab]

Ya the dumps in like the shape of the lower break light......that would be sick ! And we are putting the stock under belly cover over the pump soon as we install the quieter one.

[@josemartinez-dd4yg]

@@GearheadsAutofab, car looks good. The dumps out the brake light would make crazy noise, but control boost creep (if you have any now). Can't wait to see final product.

[@Fotobukku]

LOTS of Porsche's us an Oil Drip/Sump Tank from the drain. Its obvious what their function is. Could help save the turbos and headaches. They also look cool. Also plumbing the gates back into the exhaust is choice.

[@Nismonomania]

Wheels look good car will look sooo sick when u guys drop it. Sounds amazing too, no sweeter sound than a boosted vq. Can't wait to see what you guys do with the intercooler piping just worried it would be too low!

[@Brando_Z33]

Nismonomania boosted VQ37* the 35 (minus the HR) sounds kinda bad boosted. Lower compression pistons + the way the turbo alters the sound of the engine naturally, sounds bad on VQ35s at least in the case of G35s. Zs sound okay boosted

[@orlandomedina7054]

Great vids man..not everyone takes the time to explain in full detail let alone talk about the outcome ..

[@CornellW003]

Might want to make some small catch tanks for the turbo drains before they go into the oil pump. It will help the oil fully coat the pump and not burn it up.

[@MiguelAngel-cx5dq]

Im happy with 5 - 7 psi of boost just to make it more fun with the turbos realistically stock the 370GT/Z is fun to drive it has more than enough power for daily fun driving.

[@rustywrench500]

True these days anything less than 1000hp is considered slow by Instagram and KZbin trolls but they don't realise you can't use all that power on the street you don't get to enjoy the power

[@johnpowers4076]

Man it sounds good! Ready to see the charge piping installed. Props on the exhaust fabrication, it's ridiculous. I would seriously consider purchasing this kit if it ever went into production.

[@jamesbower330]

Looks like it will be a good bit of fun, very clean build, just for future reference when you tacked the turbo mount bracket under the car you should move the earth clamp onto the material you are welding. As you had it back on the exhaust pipe the current will travel the path of least resistance, so it might have arcked the bearing in the turbos. I know it sounds trivial but I've done that when I was a 2 year apprentice. Regards James

[@Korruptionen]

Thanks for sharing this build. Randomly found your videos and they are very good. I want to learn how to weld, and have a project car to build this year that should be a good learning project. Keep up the great work!

[@georgebonney90]

i think this is badass,if ur experimenting and learning ur doing it the right way,thx for taking the time to record all this and putting it out,keep it up brother

[@2ANinja]

Do a independent oil pump and tank for the turbos. You’re probably gonna have drain issues if you try to run lines back to the pan. You could easily mount a tank and pumps in the trunk or under the car.

[@crave8687]

Wheel looks great. I like that set up of the rear turbo. I know only knew of BMW doing that with the M5 some years ago.

[@vincentvaldez4862]

Are you planning on making a kit that the public can buy?

[@strider5119]

An exhaust shop can do the welding side of things, the lines can be bought anywhere. The overall thing isn't hard to do, BUT, you should research the get the correct stuff, and also look into aftermarket tuning. You can usually get away with a couple psi without tuning, but you should definitely look at an aftermarket ecu or one of those boost controlled fuel pressure regulators or similar.

[@GearheadsAutofab]

Yes, hands down trying to tune the stock ecu for efficiency changes with egt fluctuation is the most challenging part. If I did it on a aftermarket ecu I could build out a aux modifier table. I think any one can build a rear mount kit,

[@DracolegacyOfficial]

no, remote mounted turbo systems are patented by STS Turbo who is currently owned/partnered with Holley. trying to manufacture and sell kits would be a patent law violation but there is nothing stopping you from coming up with something for yourself.

[@GearheadsAutofab]

They only patented the oil return system, but I met mark squires when he first made the sts kits. I am only looking for a awesome boost solution that’s easier and cheaper for the z community to go fast.....that’s why I started Nisda www.nisdaautosport.com we have new z parts coming out later this year.

[@itsJoshW]

Cr2p? I have them on my turbo 350z. Love it lol. Sounds sweet. Hope to see the intake piping in ASAP so we can hear some spool!

[@kiyabcs]

I think you have the best mindset in doing this. People need to do this more and just experiment and see what happens. Good shit man.

[@iggibars]

I love how this project is turning out! The exhaust work looks beautiful!!

[@cbernstorf]

I appreciate the balance you have found between taking pride in your work without taking yourself too seriously. You are literally completing a project that I have wanted to do for years. Using affordable parts and basic tools/skills you will create something FUN. It may not break land speed records, but it is attainable.

[@geeaye64]

Excellent video. I know your trying to keep the cost down, but you could have gotten the Z1 Motorsports oil pan spacer with ports instead of drilling into the upper part of your oil pan body. I would add a gauge for your turbo pressure and boost gages(I know you probably already have).

[@ZEPRATGERNODT]

George H. Arnold IV Z1 Oil Pan Spacer👍🏼

[@msp845]

I've had idea of doing a similar setup for about a year now. Can't wait to see the results!

[@antaviusmitchell7560]

If you swap the turbos around (right moved to left and vice versa) it would be easier to route your tips because they would be on the correct side.

[@GearheadsAutofab]

Yes true....I thought about that a bunch before doing it. I would like to try it the other way in the future to see if I liked it better. Especially because I could do different things with the turbo intakes as well.....

[@07wrxtr1]

Really hope you can bring this to market, curious about the whole economies of scale. I would love a simple kit that just bolts on, not tapping the oil pan.

[@GearheadsAutofab]

You can use a oil pan spacer and return oil that way with out drilling.

[@awdrifter3394]

Gearheads Autofab or just cross the exhaust pipes left and right

[@strictlyimports11]

This is awesome. Can’t wait for the next vid!

[@marin6201996]

Great stuff jarom ! Can’t wait to see the finish product 🤤

[@migo__suave]

How do you turbo your car?

[@AJIMPORTS]

For the oil feed. Maybe you should put a gauge on that line to see what the pressure will be at the turbo. Their is a chance you might have pressure drop over the distance.

[@sambonelife7485]

Putting your oil feed line high up on the oil reservoir, could cause your turbo system to Star for oil. Maybe under acceleration it could slash the back of the pan and cavitate did not send oil to your turbos? Also you need to make sure you keep an eye on your oil level cuz if it were to drop any at all the fact that it's up high would cause it to cavitate even at idle.

[@neilw5198]

Very nice set up, i,ve heard biggest problems with rearmounts is expansion and cracking in exhaust , need extra flex joints.

[@LilBellow]

Dude, love the videos. Thanks for doing this. Im really watching. I noticed something, you may have some slight problems with boost creep. Since you mounted the waste gate at a 90deg angle and not a 45deg. The exhaust tends to flow right past the gate when at higher RPM when its mounted at a 90.

[@GearheadsAutofab]

Yes it’s called “wastegate priority” I’m aware of this. I don’t think In this application it will be a problem .....but we will see.....then I can let everyone know so they can do it different if needed.

[@charlesstillwell1985]

I was thinking that the wastegate being at a 90 might be better because of how far the turbo's has to push air in the charge pipe maybe won't have as much or any lag from the turbos. But I'm no pro a turbo's

[@gingerbreadman5756]

One word two syllables... badass! Aesthetically I think the exhaust tips are sticking out too far but that’s just my opinion. Sweet project!!

[@s13turbo]

Nice project! I'd introduce the wg dumps in a more shallow angle or it will create a restriction.

[@austinbrown924]

Only braided line on my entire car is the oil feed which is 3an unrestricted which was 25 bucks used 5/8 fuel hose for return and barbed fittings

[@jhernandez4636]

So I would definitely like to do the same set up, are you willing to list out all the parts you made and used? Like list what the “KIT” would include. What turbo did you use or get it from and how much? Please reply back I would definitely like to know

[@RagingBullNuts]

14:22 Note! You do not want vacuum to the oil outlet on the turbos. Needs a free flow, hence the drip boxes people use. I'm sure you know that but as I would to a friend, just a reassurance heads up.

[@DirtyGarageTx]

What do yal charge to make downing like this for a 328i bmw I’d like to do a resr mount and would need t3/4 vband adapter time my exhaust....where in Texas are u located ? I’d like to get in touch with Yam see what can be done for s budget friendly rear turbo ,I’m n Houston tx

[@areBtwo6]

Impressive that a complete twin turbo kit fits right in place of the factory muffler! Definitely going to want to open up the cats, y-pipe and mid-pipe. lots of restriction there. Also why not 3" piping?

[@MiguelAngel-cx5dq]

What if you mount the oil pump in the back with a filter and 1L reservoir and have a separate system for the turbo. Would that work? Im guessing it would? If it does it would save from drilling the oil pan or using Z1 oil pan spacer which has the oil fittings. It would also save from the long hose and near driver oil pump noise. I hope my suggestion works thank you for your videos they are fun and informative.

[@johny79action]

Stones gettin sucked into the turbos is a problem I can see, but nice idea and awesome fab work ;).

[@jolmeaki]

Man I love those wheels on the white paint.

[@Resqueda01]

Please lmk when you start selling these. I’m a big DIY person. Please!! 😁

[@stonesofetown6767]

The z cars were made to be turbo’ed. Look at all that space! I’m doing the same on a v8 MGB and have waaaaaay less space. For the oil pump I’m using the same but found a dc motor driver that carries the voltage to the pump so you can run 6 v or half the pump rpm and it still hauls oil like a mofo. It’s at least 4 times quieter. Also you could mount the pump on grommets should lessen vibration noise from the pump. What size drain fittings and hose did you use? I have herd the biggest you can fit is best. Also you may find that the return pump need air behind it like plumbing. Turbogriff solved this with little oil pans for the turbo that have a vent line so the pump can pull freely. The oil return is the biggest hurdle fore sure. Can you post longer term updates on this setup as it comes

[@Z33Garage]

Any reason a pan spacer w/ tap would not work well enough to push the oil back into the pan for this setup?

[@austinreed2822]

My biggest concern would be dirt and stuff getting into the turbos. I hope yall plan to build a box for the air filters to reduce that issue or may build a flat bottom rear diffuser to reduce drag and stop most of the dirt.

[@theonlym12]

The collars on the an fittings are reverse threaded inside. When assembling them onto the hose, spin it the other way and it just goes on with very little effort

[@pospc2]

What turbos and pump?

[@383mazda]

What part of Texas are you from? I'm up north of DFW, I worked for STS turbo back when I was in college - we "hung" most of our turbos using the stock exhaust / muffler hangers, with brackets welded to the downpipe and intake pipes. That way turbo wasn't hard mounted to anything and could flex with the exhaust. Your car will sound awesome when finished!

[@joeyphaze7509]

Good work on the fabrication man!🤘🏽

[@Blackinterceptor999]

I'd honestly just use a remote oil system away from the engine, what if the lines get broken, crushed or just ripped off the car? There goes all your oil for the engine! I'd just stick a small tank in the trunk run lines to the turbos and run a cooler with a fan...besides your gonna need a pump to get oil anyways... Looks nice though.

[@brian1157]

Awesome! The only thing I don't care for is how far those exhaust tips stick out now. Can't wait for the video!

[@Bigboats619]

When you add turbos to a non turbo car aren’t you supposed to add a bigger oil pan for more oil? how about the air/fuel?

[@glorianyrivas5735]

What do you mean. Make sure you tap it on the oil return ?

[@knightrider509g.4]

How many psi are u running your oil pump

[@mikefluellen9964]

that exhaust sounds sick!

[@eranjones5994]

Dude your tha man! I can't wait to see the videos like on ( just when you thought you were fast). Supra's and Lamboes turds won't know what passed them. Good luck bro!

[@timothydodd7412]

Do you have a complete parts list on any of the vids?

[@angelcabrera2964]

wont you have over boosting problems since the waste gates are at 90 degress compared to the exhaust, the exhaust gases will just flow past the wastage inlet right ?

[@KingOath]

angel cabrera It depends man, it’s not ideal but that doesn’t mean it won’t work. There can be quite a lot of exhaust pressure in some turbo setups, sometimes in the range of double the boost pressure. So even if the wastegate is in a shitty position it will still release that pressure when it opens. Obviously if your particular engine setup needs to vent a lot of exhaust to control boost then yes, you might have flow problems and boost control problems with a bad wastegate angle like that. But so long as enough exhaust pressure can be released through the gate to control your particular setup then it’s more or less all good.

[@KingOath]

On my truck, a 4cyl turbo diesel, I really didnt have any good options for wastegate placement. It runs a log manifold with the turbo flange between port 1 and 2, and the wastegate flange between port 3 and 4 with the gate sitting 90 degrees to the manifold. It’s a horrible setup in theory, but it works just fine as the turbo needs most of the engine’s exhaust to make the set boost, so the wastegate doesn’t have much of a job to do getting a little bit of pressure out

[@angelcabrera2964]

Marty McFly i feel like a setup like that on a diesel would be more ideal since diesel motors run much more boost without having to worry about over boosting problems causing damage to the block, and with the wastegate at that angle there would be less lag since not all the boost pressure is being relieved from the exhaust, but idk i hope they dont get any over boost issues bc that setup looks fucking sick

[@lagunasmiguel5]

wow sick af I would like to do that to a 6.4 jeep

[@1hunda100]

Dat bih sound good nice job

[@losminatoatlanta3164]

You should put the relay in side the engine compartment so it won't get wet when is raining

[@chriscole2020]

Maybe I'm wrong but isnt the waste gate suppose ed to go in the air feed path not exhaust path to relieve excess boost pressure before entering the motor?

[@darius9521]

you're thinking of recirculating or blow off valve. wastegate relieves exhaust presure before it enters turbo

[@oceansidepirates23]

Keep the good information coming. You guys rule 👍

[@magatilithertz8414]

Did you think through how to properly filter the air going into the turbos being that the wheels will be kicking all kinds of dirt and dust into them?

[@gaboonv1per]

Hey.. I like your enthusiasm and your design as far as the route that you chose to run the oil supply.. but thinking of what would happen if I had a leak somewhere in the line more than likely it's going to cost me an engine.. I think you should have just ran a separate reservoir for the oil.. because you did put in an oil pump just for the turbos.. That way if it were to leak or blow a line.. Then your only loss would be a turbo.. not an engine.. but still your work is very good.

[@GearheadsAutofab]

I thought the same as you at first, on paper it sounds good, in real life it’s really just super simple to run 2 lines that have no less chance to leak than normal turbo lines, oil is the thing I worried about most on the car .....and funny enough has been the easiest part with no issues so far.
