The Turbo kit i have hase 2/T4 Turbos would i have to do anny more to the moter to install it. i no you need low compression for turbos right. well if u could help me that would be great..

Re: i have some qustshions

You need to list what the rest of your setup includes...it's hard to figure out what you have based on that....um....description.

...and for God's sake use spell check or proofread...damn....

You're probably going to have issues if the crank is in the pistons, that definitely hurts performance. It adds too much weight to the pistons and the motor is going to have a hard time revving to keep up with the turbos. Take the crank out of the pistons to lighten them up...you might want to bore the pistons out too to really lighten them up..................

Glad to hear you've replaced the belts. You'll have to make sure they are in good shape for the turbo pully's.

We tried all that and the car started bogging out of tight corners because there wasn't enough weight in the pistons to keep momentum - it's really important to have crank in pistons for a turbo setup because you need the extra torque until the turbo kicks in.

Re: i have some qustshions

Try the smaller turbo pullies like TAdan said. They should spool up faster.

Re: i have some qustshions

How low of compression are you running? You don't want anymore than 85 PSI when you do a compression test on the motor, otherwise you might run into problems with boost.

Re: i have some qustshions

Drill a small hole through the top of each piston will reduce the compression nicely.

Re: i have some qustshions

On your next trip to Summit, you'll need:
-new fuel system (complete from fuel pump to injectors)
-new ignition system
-new pistons, rods, rings, crank, etc, etc, unless you want to send your crankshaft flying through your oil pan.
-and honestly by the time youre all done with this youd be better of with a mild 350 crate in there. Trust me.

Good luck tho bud.
