I plan to get the PR3 ECU and S2 IM later down the line, basically I am asking can I put the B18c in my 90 RS with stock ECU and reuse my stock IM and EM. I know I wont have VTEC. I just want it to run my car for now. Thanks!
intake manifold: no, it won’t bolt up
exhaust manifold: yes, it will bolt up
ecu: it will run, but you’ll throw tons of codes and performance will be horrible.
just save up a little longer and do it right the first time.
I will get the PR3 then. Thanks for the reply!
