.58 Cold, .94 Hot Stock Port S4. Haltech, 1600 secondary's.

How will this thing act? Also, where can I buy different Turbines (if at all) to change the A/R's if I am not happy with it?

And please excuse me if these are simple questions...everyone has to leanr sometime...thanx.

 

which gt40 is it?? there are multiple gt40 compressor wheels

 

I wish I knew. Im pretty sure it isnt the 88, but im not sure...how can I find out?

Also I forgot to mention, I will only be running 8psi normally, 12psi when I feel the need.

 

take the compressor housing off and measure the small diameter and large diameter of the wheel w/ some calipers and then post it here

 

Ok, will do. I wont have the car back untill this weekend but as soon as I get it done ill give you an update.

 

Got the car back today. I havent had a chance to measure the wheel on it, but this thing acts just fine at 7-8psi. Comes on right around 3500rpm. Im sure when the time comes, and ive got more supporting mods and crank the boost up, it may not see full spool boost near as quickly, but im happy with it for now.
