Well i am not the best at sizing turbos so i ned some help.

I will tell you my setup and what i am going to be doing to help you in telling my witch turbo A/R is right for me. I am really just trying to go big enuff that the turbo will not strain to push enuff air at the higher Rpms that this motor will NORMALY run.

This is going in a AutoCross,Road Racing Car, It will never see the street so emissions are no problem. And this engine is ready for 9.5K easy, and will proably be in the 6-8K Rpm range most of the time. So spool up is not a big issue, becuse the motor is up there most of the time. You understand

Looking for 300hp or 400hp, 400hp is a little on the high side for road racing, dont you think.


Ok

85, GSL-SE 13B, 3MM, Front and Rear TII Plates, Bridge Ported.


The exhuast is pretty stright forward, It is going to be totaly custom, Two pipes 2in out of the motor and collected into the turbo , with a 1 1/2in pipe to the Wastgate, the turbo outlet is going to be proable 3 in out infront of the front tire, (Front Fender) I no it is going to be LOUD but i want it this way.

Going to be running a Stock Ignition system with NO Advance in timing, and a Mega Squrit V.3 system Running the 4 to 6 fuel injectos that i want to run eather.


Still working on this setup but building the car frist.

Thanks for all the Info in advance.

 

Forgot to add that the Exhuast is going to be ported Large

 

I all ready have this one, BUT cant get the sizing on it, dont no if it is to big or small

 

Come on,, Anyone
