What are some other engine mods besides intake header and exhaust? what would I see the most gains out of and what are expensive what not, what are hard to find what not? Thanks

 

engine porting=more air=more fuel= more power, apexi SAFC to fine tune fuel mixture, turbo it then add bigger injectors, stand alone ecu. $$$$$$$$$$$$$$$$$$$

 

You could port your intake manifold. Check the archives for a good how-to thread.

 

I did that along with the TB mod at the same time, it was awesome! Before power would die out near redline, now it pulls hard past 7500, but I dont shift further than 7500 cuz im scared to haha.

 

i have seen people talk about a tb mod but what the hell is it? I am assuming it has something to do with the throttle body. Can anyone point me in the direction of a thread that explains it because the damn search on hear won't let you put in words such as "tb" because they are too short.
Thanks
