Nice find man, Explained it better to me.

 

So say i was getting a mild port. its going to add 200hp more? or it will let me hit 200hp? by adding like +50hp? Im assuming the 2nd one.

 

well, it all depends what the rest of your set up is like. but if you have a 6 port, dont bother.

 

no hope for me then.

 

Yep,I have always wondered what a 6 port max HP would be on a huge street port or even a bridge.Probally just close of 200 ?

 

im interested in finding out, but instead of doing that. i might as well jsut finsh saveing the money and get a TII motor and do a swap.

 

stock TII engine your looking about 200ish too.I think 187?

 

yeah, porting on 6 ports doesnt help very much at all, and plus they have that stupid restrictor in the exhaust port on the 2nd gens. if you want N/A use 4 port, they flow much better. you can use t2 housings ported and n/a rotors and run a different intake manifold and header and make a pretty decent motor.

 

If he did want to go 4 port,n/a FI.. I dont think theres any OEM FI uim/lim that will mount and work,that would mean going to RB intake/carb..

Heres an example.
There was a so called "racing team" who used to post on TR,that claimed porting sucked etc etc..
Well they had a FC with a "bridge port" 6 port engine/carb set up.. and my friend beat him with a stock FC-SE only mod he had was a cone filter.
