4-2-1 Headers
 

Just a quick question. Does it matter what size headers are for integras between 90-93. Are all universal? i have a 1.7 vtec motor and it came off a 1.8 non-vtec. will it still work out?

lengths might be to the cat, but it will bolt up to the head. 90-91 are different from 92-93 in design 4-1 and 4-2-1/flow/o2 sensor location/length/flange angle - are all different

does it still work out if you make minor modifications?

i have a 1.7 vtec motor and it came off a 1.8 non-vtec

clarify that first ^

so you have a gsr motor that came out of a ls/rs/gs and now what?
what is going into what chassis and year specifically and i can answer it

i think hes saying the header is form a 1.8 and he has a 1.7 motor will these 2 work together ?

oh sorry for the confusion. it came off a 91 ls, i have a db2 and i was wondering if it could still work out.

yes it can work but your gonna have to shorten your mid pipe and reweld it. THe 91's are longer than 92+. If your going through all that trouble why dont you just put a posting to grab a real 92 header and jsut replace yours. What is the problem with your original one anyways?

i wanted to go aftermarket.
