Someone is Finally Fabbing upgraded turbo inlet pipes!

bryce · 03-22-2012, 02:36 PM

saw this on another thread. i've always thought the stock turbo inlet pipes were too restrictive at the boost levels we're running. more details (remove spaces)

Good luck with the rear one...

marcvtec · 03-22-2012, 03:01 PM

I do not think the cost of doing this will justify the power gains.

Brey335i · 03-22-2012, 03:02 PM

Front is alright but the rear one... That will require ninja capabilities

bryce · 03-22-2012, 03:05 PM

they should have an update on the rear pipe today or tomorrow. they said they bent the heat shield back a few inches and they have clearance now. they didn't need to drop the engine, either.

I'd be really interested in seeing this work out. If you just have to move the heat shield a few inches and not have to drop the engine, this could be promising.

that moves things into the realm of feasible

Like I said this will take a little modification of the heat shield and the pipe will not be in the stock location for the rear. the route will be different but will end in the same area as stock with as little piping as needed. Reason being we want this to be a bolt on setup. Final price will be determined one the project is completed. But expect between 450-650 price range for everything to do this on your cars.

this is what the car owner recently posted

Agreed but I doubt it, not much room back there.

All I know is that when I had to replace the rear pipe, it required lifting the engine or dropping the transmission. Pretty sure you can't just "push" the heat shield back or else I got fked on labor

you got fucked on labor

You can do interesting things if you aren't concerned about modifying OEM parts.

mave198 · 03-22-2012, 07:06 PM

Very interesting.
What are the max gains from this type of mod?

There are so many variables it is hard to say.

The 300zx Twin-Turbo crowd sees good gains from upgraded throttle bodies and 2.0" to 2.5" turbo plumbing upgrade. Like 30-40whp at 20psi.

iBoost · 03-22-2012, 07:37 PM

That actually has a lot of potential! Nice work, cant wait to hear the results!

pits200 · 03-22-2012, 07:40 PM

Even if the piping is rerouted, wouldn't the work still need to be done to remove the old one?

they haven't lowered the engine at all, so i assume they probably cut the stock rear turbo inlet out with a dremel drill....

roozie2001 · 03-22-2012, 07:50 PM

good info. keep us updated

Zebra99 · 03-22-2012, 08:14 PM

I'm down for upgraded plumbing

marv85 · 03-22-2012, 08:29 PM

seen this on the other forum... very interested in this.

BrianMN · 03-22-2012, 08:35 PM

Very cool if this works out!

Please tell us you got a baseline dyno so we can actually see if this works?!
