ecu and motor swap

[Go_Fast]

can you put a stock b18a motor and a pr4 ecu into a '95 integra gsr and have it run fine?
if so what about the extra vtec wires?
will it pass emissions?

[Cynical 1]

it will run.

you will have to do some rewiring.

emisions - only if everything is hooked up, and the engine is the same year or newer (with newer emissions exuipment installed), as they will check.

what if i get a b18 block, b16 head, and a stock p28?

it will run but not good. a p28 is for a d series. the engine set up will work but you need a different ecu.

what ecu should i get?

by b18 do you mean ls or gsr? if you are doing a ls/vtec then you will need to get it tuned.
