Rear mounted turbo? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Addicted2Kouki · 02-12-2008, 02:49 AM

Anyone ever try a rear mounted turbo?
I know domestic v8 guys do it.

I would imagine more lag for our cars
...but does anyone have any info on it?

e1_griego · 02-12-2008, 02:53 AM

Considering all the conventionally mounted turbo options, there doesn't seem to be much point for an s-chassis. I'd be concerned driving around a low s13 with turbo shit hanging out by the ground, anyway haha.

Jesus, I've never seen that in my life. I wonder if the power being produced is the same with a traditional turbo. BTW, does that have any benefit oppose to putting it in the front?

Addicted2Kouki · 02-12-2008, 02:57 AM

I would imagine the only benefit is keeping the engine bay looking stock.
that and maybe the fact that sometimes you dont even need an intercooler.

but its flaws probably would be trying to put together the piping and a slammed s-chassis.
or trying to locate a boost leak.
plus more pipes to fill = more lag.

D1GP · 02-12-2008, 02:59 AM

i believe since american cars have bigger motors, there is less room under the hood, and that is why they resort to the rear mount turbo.

would be stupid pointless for an s-chassis though. more lag and if you hit a puddle you're fucked.

Kn1ves · 02-12-2008, 03:00 AM

Theres supposedly no noticeable turbo lag from that set up even though theres a ton of piping. It wasn't some hack job.

Benefits would probably be, lower temp at the hood.. passing visual inspection...

Cons would be.. tons of additional piping/weight which can be countered by more power

actually since most of the piping is in the length of the car and not in the front, it wont be worse than an fmic

Addicted2Kouki · 02-12-2008, 03:07 AM

interesting points you make there.

89singlecamnoob · 02-12-2008, 03:22 AM

i remember seeing this done to a corvette on some Speed channel program...distributed the weight better (however minimal that might be), they didn't need an intercooler, and basically kept the engine bay less crowded. seems silly, and it certainly wouldn't work on some of your guys' cars...constantly worrying about scraping more than just aero on that speed bump

Koopa Troopa · 02-12-2008, 03:50 AM

It wouldn't be worth the effort on a 4 cylinder powered S chassis car. It's possible on V8's considering the exhaust flow of such engines. Your 1998cc motor isn't going to produce enough exhaust flow to spool that thing at a decent RPM..

Other than being cool there's really no reason to do it. Can you imagine trying to run 90mm intake piping through an S chasis?

Actually looking at that setup it seems like a cheap way for V8 guys to run a single turbo...

it is something to consider for the V8 240sx guys.. maybe even for the VQ

Guys, this is STS Turbo territory: http://www.ststurbo.com/

They've invested a lot of money in this technology and hold several patents on it: http://www.ststurbo.com/patent

Patents are here if you're interested:

http://www.google.com/patents?id=bWU...J&dq=6,745,568
http://www.google.com/patents?id=bW5...J&dq=7,134,282

It's a good way to keep the engine bay clean. That's their whole rationale for designing this system.

If you're going to design your own system make sure you understand the extent of their patent coverage and don't infringe. STS is very aggressive with their patent enforcement.

I think this is true. However, I am good friends with Brent Grigsby who owned the blue GTO about half way down on this page... http://www.ststurbo.com/fast_customers
That car was SICK. I remember him telling me that he rolled up on two guys that were racing each other, 1 in a supra, and the other on some insane bike, and he passed both of them before they knew what was happening. LOL

jrmiller84 · 02-12-2008, 07:23 AM

God forbid you drive the car through a deep puddle of water during a rainstorm considering where the intake is located...

nevaland9 · 02-12-2008, 07:53 AM

heres a video of a Z with that kit..it sounds pretty crazy..the whole sleeper look gets thrown out of the window once you drive by someone.

McRussellPants · 02-12-2008, 08:08 AM

total dildos.

STS still trys to pass off the super 60 as a sellable turbo so they can pretend to be "engineers" all they want.

*brndck* · 02-12-2008, 08:28 AM

the first article i read about sts, they were claiming that since the turbo is after the catalytic converter, that it would somehow be exempt from carb and therefore street legal. i lol'ed when i read that.

bloodangels13 · 02-12-2008, 08:47 AM

Im all about the APS TT kits..... my dad wants to get the c6 vette kit or comaro kit and mod it to work with our 69 firebird when we drop in the ls6

Risu2112 · 02-12-2008, 08:52 AM

I lol'ed

Visual inspection ALWAYS includes a through examination of your exhaust piping! Also yes more piping = more lag, any one that says otherwise has failed physics and should not be giving advice on the subject.

UNISA JECS · 02-12-2008, 09:04 AM

I'd be worried about something in the road hitting the turbo and the oil return since the turbo is only a gravity drain more less.

i need tires · 02-12-2008, 09:28 AM

wow i think im the only one that was thinking this... but how about dont SLAM your car if you have this type of set up lol

but i see a lot of these set ups on trucks, which is perfect cause ur engine bay isnt cluttered, no intercooler needed, and in most trucks u can run a huge ass turbo under there with no problems.

i like the rear mount set up. i would love to run it on my truck some day!

ripnbst · 02-12-2008, 10:07 AM

These are better suited for people who are more into drag racing, seems lots of 240 people myself included are about response and overall street performance.

i must be missing something here, because isnt that how a normal turbo setup works anyways, spooled by exhaust gases..

he is talking about a 2.0 or even a 2.4L engine wont be able to produce enough gases to spin a turbo that is 4ft away from the exhaust source compared to when the manifold is right up against the head.

Yes you are, the turbo is located a few inches from the exhaust valve where the temperature is hot and the velocity is high. Not a few feet of exhaust piping where the exhaust charge has plenty of time to cool.
EDIT: i need tires beat me.

my buddy has one on his 350z. Lag is not an issue for him at all. I can't remember what website it's on, but when I remember I will post it up.

hotlavaflow · 02-12-2008, 12:18 PM

My turbos are low mounted (not rear mounted more like mid-mounted) and I had lag. I had to redesign the intercooler piping for better response. It worked out pretty nice. T28's off an R33 GTR. Originally they didn't really start spooling until about 3500rpm but with the X-pipe it starts at 2800rpm.

I know a guy running the rear mount on a V6 and there is a bit of lag.

i like! very very nice set up!

allntrlundrgrnd · 02-12-2008, 12:30 PM

damn thats a wild setup, what kinda car? 240?

azndoc · 02-12-2008, 12:31 PM

I saw this kind of rear turbo set up on the speed channel before also.

Forgot what car it was.

But I wouldn't do it personally because of drifting and all the dirt drops that I do.

I'm pretty fine with the conventional set up.
