I still have yet to finish all the modding to mine haha, i have opened up the injector side of the porting but going to drop off the manifold at a machine shop to open up the throttle body side to 68mm. I picked up a Professional Products 68mm throttle body couple weeks ago.

Can't wait haha.

I havent even done anything to my Tb side , is it really needed or just more beneficial?

hahaha

you gave the motivation to get it done, plus i was too embarrassed every time you asked so had to do something so i had a good answer for you

Yep, a very big prelude shaped smile

Feels Great to be back in one again.

Im not 100 sure what was causing the problem, i was clueless but the garage did say ignition was advanced

I have a big to do list now, and a lot to save up for lol.

You can go up to a 68mm throttle body, the stock port on the intake manifold is 62mm so if you add a 68mm throttle body then there is a 6mm restriction in air flow!

SO porting the intake side to 68mm will give you more air flow with less restriction
