or both such as the 4t60?-- will that one work? or still need the axels and other things.. i was going to buy performance mounts anyways either way

you need to have custom mounts made, not performance mounts.....

alright.. for now i think it will be ok to run the stock tranny at a low psi like around 6-9 max at first. after a new tuned pcm i dont see why the stock one would be that stressed unless i go balls out all the time.. then later if it has problems i can swapp something then.

With an open exhaust and low boost, it might perform pretty well, but as critical as it can be in a turbo application, I would not take the risk.

There's no risk about it, it just comes back to choosing the right core to begin with. If all of a sudden you want to add all kinds of boost, and your intercooler is large enough to still be efficient you're fine. But if what you have is just the right size for the low boost setup you're running, you'll need to get a larger core anyway.

As for the 500hp claim, you'll have to take that up with ETS. I do know they are a very reputable company in the DSM/Evo scene with excellent customer service and their products have been dyno proven to perform very well.

A tuned PCM does not all of a sudden let the tranny handle more power. You'll be just fine on low boost, around 8-10psi depending on what turbo you choose. When you want to start pushing some bigger numbers, you'll need a built tranny.

i know the pcm doesnt make the tranny stronger but if i tried to run it with a turbo and not flash it then it would be horrible on the whole motor lol...

yeah the setup we have going and the turbo we get , we will will be starting at around 6-9 psi

Which turbo did you choose?

not quite sure yet. have been doing a little looking around tho. whatever i get though will not be the most powerful shit youve ever seen i want to get something up and running first see how the car reacts and then add more from there...

the last car i assisted in a turbo with, the guy insisted on this great turbo he found and how expensive it was. lol and he bought it and lets just say 4 days later his 2.4 l motor was no longer alive

where would the best place to run the oil lines form be?
and anyone know where i can get a battery relocation at?

kwhauck · 04-20-2009, 09:27 PM

ask the turbo guys for sure and
summit racing for the battery relocation

You just tap off the oil pressure/level sendor with a brass T (at least on the 2.4L).

The return line is simply run to the oil pan. Drill and tap a hole and put it in. No biggie.

There is a slight risk to the engine associated with it, but since I have no firsthand turbo experience, I might botch up explaining it. So I'll try to find some more sources besides Bell, and present an explanation in another thread.

Lol... the hole is drilled and tapped, AKA you make threads to screw in a fitting that runs a hose to the turbo oil outlet.

If there was any risk, the car companies wouldn't put a horizontal type intercooler in their factory turbo cars, or aftermarket companies wouldn't make them in larger cores as upgrades, or race teams wouldn't use them for high horsepower track cars, or some of the ultra high horsepower dyno queen/drag cars wouldn't use them. The vertical intercooler may be better in certain aspects, but the horizontal intercooler certainly works and works very well, no matter what application it's for. It's been proven time and time again.

so will gtp fuel injectors work on the 3400?
im having mixed answers...

kwhauck · 04-23-2009, 12:19 AM

honestly if you are just starting at 8lbs, the 28lb tb/envoy injectors should be fine.....

i thought the trailblazer ones had a different injection system?

so the gtp ones would work though? but there are other option other options within gm cars then, good to know
