Hi, looking for you advice and experience.

I own a B18C4 which is a UK car, push 169BHP. I've been told that it is similar to the USDM B18C1 as it has the dual intake manifold whereas all type r's have single intake manifolds. (please correct me if I'm wrong)

Please could you advise me on what modification I should carry out to obtain a possible 200bhp or more with out forced induction.

thank you

PS all UK ITR after 98 were B18C6 and all before were B18C3 however somewere inbetween were B18C5. This civic is a VTi and not a Type R (UK VTi = US SiR or is it Si)
