Should I just get a tb or the whole D%#$ thing?

 

Neither. Do head work.

 

the whole thing.

 

both.

 

Not satisfied with the Y8 manifold chim?

 

^ have a S2 mani and TB. satisfied with both.

 

I just want to upgrade. If i went up to just a 62mm tb, am I looking a small or decsent gain?

 

gain will be like 1hp with both...if that. the biggest gain you will see is throttle response, which will feel like bottom end tq and power.

i like kedawei's suggestion. you will see both a poewr increase and a response increase with headwork. a good PnP job, 3 angle valve grind, and maybe a good aftermarket cam/valvetrain to top it off could net you up to 20hp at the wheels.
