just curious how much can be gained by porting the turbo and maybe the exhuast manifold a little bit?

where are the weak spots as far as flow anyway?

would this help spool at all or more or less just make for better flow?


and can much for improvement be made in the intake manifold as well for porting?

 

Before I got my current T60-1 turbo, I ported the stocker and manifold while porting the motor at the sametime and I didn't really notice much..maybe a little. I did run a 12.1 @ 116 w/ that setup. I had a G-Force chip, 850's and a Bosch Type44 pump.

 

The T-60 setup you have. How much HP did you notice? I'm looking at a T4.

 

you ran a 12.1 on the stock setup with bigger injectors?

what were the mods on that car? im not calling bullshit but i'd love to get that kinda speed outta mine

 

which spots on the turbo though do you need to worry about porting?

any change in spool time or boost/boost creep?
