has anyone on these v6 boards ever perfected the rear mount? i think it would be a good idea, something like the rear mount corvette setup- turbo in place of muffler, no need for intercooler under 10lbs of boost, and reduced underhood temps... any takers??

 

I looked into this idea quite a bit about two years ago. I'm not saying it's the best way to turbocharge an engine, but it does help performance. There was one guy who remote turbocharged a 3400 V6 swapped Cavalier, and he made some great numbers out of it.

The parts list I compiled for a remote-turbocharged V6 Camaro would be...

These headers will keep your exhaust system volume fairly low, but should lessen flow restriction compared to the stock exhaust system. Ceramic coat inside and out to keep as much heat in the exhaust flow.

This intermediate pipe should be what you cut and weld a flange onto for your turbo. Again, it would be a good idea to ceramic-coat this, too. You'll want to keep as much heat in the exhaust flow as you can.

The turbocharger you pick should probably be a T3 turbine with an A/R of around 0.63 and a T04B compressor. That turbine should give you relatively good spool for the displacement you have while not being to big of a restriction to exhaust flow. And the T04B compressor is best at flowing at lower boost pressures which is what you'll be looking for. You'll also need a wastegate if the turbocharger you get isn't internally 'gated.

You'll also need some kind of tail-pipe after the turbocharger, if you want.

You'll need an oil-pump to return the oil from the turbocharger back to the engine and a lot of oil-line to feed the oil to the turbo and back to the engine.

You'll also need a lot of tubing to run the compressed air charge to the engine. An intercooler is something else to consider. One school of thought with remote-turbo set-ups is that all the piping for the compressed air charge provides enough cooling surface to not warrant an intercooler, but others say that an intercooler is always a good idea.

That's what I've got from all the research I did a couple years back. I decided not to go this route, though.

 

I still have delousions of notching the pass floor so it can mount right on the end of the Y pipe, only cutting the Y back a little

 

I still question why do that when we have so much room in the front engine bay. I too thought of this idea when I first wanted a turbo. But after seeing the cost of a good scavenger pump and then the cost of the piping and time of fabrication, I then decided that I should be grateful of the amount of room up front and use that insted of the RMT.

 

having to screw with the exhaust system, broken donut studs n manifold studs, more so I don't want to screw with the exhaust flow to much, doing so just takes away power it has stock, then the turbo has to make up for that plus add what it can.

A simple 90* turn out has killed my top end rpms and the speed I gain those rpms before, I don't want to daisy loop the exhaust to reach a turbo and end up with only half gains over stock. that woud be going backwards.

I can rev fast and hard to redline as is, when I had that 90* on there it fell flat way before. I want it run as good as it does now

 

Horrible flow..lol


Better flow



Best flow

 

it was just a theoretical thing really, that i was kind of planning on doing... just wanted to hear the turbo communitys oppinion. ...about getting oil to the turbo, does the oil have to be directly from the engine, or can you set up a remote oil supply with a duty cycle pump? reason why i ask is that ive heard alot of stories about turbo bearing failing and in turn causing engine failure b/c shreds of bearing were routed back to the clean crank and rod bearings... my car is straightpiped already, so ive opened up alot of room under the trunk, i could twin turbo easily, and still have room to rout the charge back to the engine(plus it would quiet down my car considerably.). what do you guys think?

 

fasteddi, that thing is BEAUTIFUL :0

 

The oils has to have some heat in it, the best way is is to use the engine oil, it`s already under pressure, and is heated by the engine itself.

You could in theory add a heated oil reservoir, but then you would also need to add a high pressure oil pump, to feed the turbo, in addition to the low pressure oil return pump, adding cost and weight.

Just go under the hood, even with the poorer flowing "hack 'n' add" exhaust system, you will gain much more power easier than any other way of adding power, nitrous, is about the only exception.

Remote mount has its applications, a V6 street driven 3rd gen is not one of them.

 

self contianed oil systems on turbos have been used but only on drag cars
the main reasion is after extended run time the oil temps will climb out of control

and six is right the cut up y pipe method will be better then a rmt on a v6 thirdgen

 

Thanks but the lower picture isnt mine. Just the top(first cheep build) then the second picture is what I have as of now.

 

the last picture is mine

 

well, first, kudos to fasteddi and project 89. awesome setups dudes, secondly, i dont want my opposition to see my advantage, i plan to have the intake come up through the factory airbox spot, then cut a hole in the top of the 3" air filter i have and slide it over the tubing to hide the intake tube hole.. sneaky-sneaky...
and if i must use engine case oil to lube the turbo then so be it... , cost effectiveness isnt on my agenda(to a certain extent) i believe in doing things the way they were intended to be done, the first time. no compromises. besides, i really dig the rear mount twin turbo setup.. its something no one has done yet.(to the best of my knowledge)

 

Love your home made single piece heads and intake gasket...........

 

lmao i was using news paper to keep dirt and stuff out of the bottom end of the motor sinc ei had just assembled it, so i stuck the newspaper down then put the heads intake on that for header mockup

 

What was the guys name that made a RMT set up on a cavy?? I think he was also on this forum. You guys know who im talking about?? He had a nice little set up from what I remember.

 

This guy:

He's got videos up on YouTube of his car as well.

 

I dunno but I can't see how all that octpus of plumbing is would fit under the hood.

What?

It's been done dozens of times, so I'm not sure why you would question it.

The picture you have quoted has everything under the hood. The intercoolers are mounted below the head lights.

 

just crazy, looks like you would need the under hood room a a big 70s car.....

 

nah, you just need to rout tubing where tubing wasnt meant to go. like the corvette setup.

 

I did a cross over pipe like picture #2 for my diesel suburban.
The HMMWV header and Gale Banks engneering exhaust manifold spools the 86mm HE351VE turbo up very quick. Header on one side, manifold on the other, works for me.
Im not running nearly enough fuel so boost tops out about 14psi.

 

i did the rear mount turbo setup ran really well has air filter issue's when it rained hard and some times the pipping would pop off over 10psi ,but now im going to a 3800 gtp motor got tired of the 60* v6 and i want to try somthing new with out going v8 got any ?s pm me as i most likely wont get back to this post very fast im working on my supra right now and i spend most of my time on celicasupra.com in supra land

 

Details? Pictures? Numbers?
