which header are u using?

would 4-1 or 4-2-1 be the better choice?

TIA

 

4-1, i went this route cause it was really there already. but in truth, the b20 hardly needs much midrange help, so i will stick to 4-1. if i get a better one thats reasonable, it really don't matter.

 

On my b20b i strarted its life off with a 4-2-1 crappy *** chikara header with crush bent 2.25 piping and ran 15.0's in the 1/4 in a DA. Replaced the header with a DC 4-1 ITR copy along with k-teller SS 2.5 piping with no cat just a resonator. Went back to the track and ran a 14.6 easily, I would guess that the 4-2-1 design wasnt that great for the b20, lol. Run a 4-1 with a 2.5 collector, you cant go wrong.

 

thanks a lot guys!!

 

what size injectors you guy's runnin?

 

are you running stock cams and compression? thought about crower parts and p30 pistons? mad props bro for putting down some good times on a b20 block. i thought about going that route but passing smog is the only issue

 

sorry about that smog prob. there bro

 

what type of exhaust are you guys running? or size i should say. i am currently running 2.25 stock GSR exhaust. i was thinking about upgrading a header and 2.5 exhaust. for some reason my car does not feel like a 15sec car. it feel like a mid 15sec.
