I was watching my favorite guys since they were Shadetree mechanics on TNN now Two Guys Garage on Speed. They put a turbo on a Camero now ive seen turbo Cameros before but this one was mounted where the muffler used to be. Air intake and all, at the rear of the car. i would say it lost some boost due to the long intake piping but it made some nice Hp at low boost. Didnt catch the name anyone else see it?

I found the company website and they also have a Honda system coming up. Well at least you dont have to worry about the turbo manifolds.

I have seen this lately...they are rear mounted turbo's......

Many don't use intercooler, b/c the air cools off enough by the time it gets to the engine...

Crazy idea....seems to work....alot of piping though....lol.... 8)

I think that the lag is increased quite a bit.

Not as much as you would think..... 8)

They say that the lag isnt any different than a front mounted piece.

A bigger displacement engines, no...on smaller litre engines, there is a measureable difference.....nothing major....but its still there..... 8)

Cant you use a period instead of a smiley face :?:

There naturally will be some lag because the piping is now ten feet long. but they also say when you add a IC you will get more lag from the restriction. So since they have no IC............. 8) 8) 8) 8)

there would definately be lag from it....i would never use a turbo setup like that

10 feet of 3" pipe is about 1000 cubic inches... Just FYI. Math is FUN.

turbo on an fbody v-8 can get very expensive...when i had my ta i toyed around with a twin turbo setup..the kit was pushing 6 or 7 grand and could crank out around 800HP...problem was the engine couldnt handle the boost so figure another 4 grand in engine work to make it srtong enough

not to mention the first time you dumped 800 hp to the tranny on a strong launch you would have to get nasa to recover peices of your tranny from mars with the next probe they send

no kit for mustangs? haters.. :cry:

eh, if you put the stainless input shaft an shift work in the T56 it'd hold up a lil better.. that's what i did to mine. however even if it did hold id say it wouldnt take but a few good launches to detonate it as you said.

I honestly can only see a handful of downsides to this setup.

1) The need for an absolutely sealed & non-leaking exhaust.
2) The installation & routing of the intake ducting to the front.
3) Added heat dissipation from a turbo in close proximity to the fuel tank!!

I think that most of the other inherent problems of having a rear-mounted turbo could be worked around.

1) Get a good exhaust.
2) Just pay the $$ to get the ductwork ran.
3) Extra heat-shielding to prevent heat soak, possibly some small modifications to route air under the vehicle to cool the turbo.

Problems with Lag...
- Simply spool the car up sooner.

Problem with boost fall-off during shift...
- Simply keep the engine revved a bit higher
Ultimately if the cost of a close-ratio 6 speed wasn't prohibitive, simply lower final drive (differential to something like 4.11 or more), and get a 6 speed.
This would let you use the higher-rpm range to maintain boost, and simply drive it like I do I when I push my car...

Rev to about 5000, half-clutch it speed shift, dump the clutch and run the car back to 5000 rpm from about 3000. For me this is most effective kuz it's my peak torque range... but yeah..

I donno I think it could be done, however I know for my vehicle, which never had a turbo on it, it's basically a huge PITA to install a turbo, requiring a 200 manifold, about a 150 dollar small CT-26 turbo (stock on the 7M-GTE & 3S-GTE), and a bunch of other annoying upgrades, like drilling the oil pan, relocating the oil filter and adding intercooler, not to mention swapping out ECU's, and re-wiring the harness a bit.

The easier thing to do in my case is simply go 7M-GTE and drop in an entire turbo engine w/ harness & ECU, there's only a handfull (about a dozen) splices necessary and you still have to relocate the oil filter, but it's an entire proven working setup, with MANY more aftermarket options open.

If this rear-mount turbo option didn't cost more than what I paid for the entire car, or as much as an 89 Supra Turbo I'd look into it... but for what they're asking I'll pass. There's only so much you can do with a 20 year old engine that's only got 12 valves, and limited ECU tuning capabilities.

I like my cars like lego's.... the ability to add or remove what I want and make it how I want it.

I wouldnt be too concerned about the heat around the tank. It shouldnt be as hot as a turbo sitting at the exhaust manifold and the air going under the car should cool it off some.

yuo know, having looked that system over.. really what's the point? why would you have this setup vs. one under the hood? i know if i lived ina high crime area this is the last setup i would want.. someone with a cordless sawzall could have it in a matter of minutes. big cities are bad enuff about stealing cars, mainly imports such as the teg ect. all youre doing is making your setup easier to be taken.

I would say space it the only way I could go with this. easier installation. No drilling the oil pan stuff like that. There are a few advantages but thats only for certain people and their situation.

yea, i can see on say the lt1/ls1 cause the space under the hood is scarce.. but i think i would still go with the traditional setup. granted there may be a few less hassles with this setup, but if youre going the extra mile to put a turbocharger on your vehicle then i really dont think your main concern is ease of instilation.. usually yuor main is performance with ease taking a backseat to it.

a complete turbo setup, like lets say on a civic for example.. say youre not buying a kit but making your own from things you buy ok. it consists of.. what exactly?

the manifold, turbo, intercooler, piping, wastegate, bov, what else? just curious

basically just downpipe and exhaust work, then ways to get more fuel like injectors/fuel pump, and ECU mods..whether that's a standalone or piggyback...whatever

I am confused...why wouldn't you have to drill the oil pan? How is the oil going to get back into the system?

ok, so what youre tellin me is.. all id have to buy is bigger injectors, a computer which i allready have.. perhaps run my car a few degrees retarded in timing? and the other stuf whch i stated in the earlier post, an i could tuirbo my mustang?! :D

i may have to look into this..
