Ok, my friend has a 1991 Honda Prelude Si 5spd, The engine is a B21A1, He has an intake and a full exhaust. Now the problem is when he goes to full throttle in any gear there is a violent surge that kicks the whole car back. It seems like the engine stalls, but it is hard to tell. Has anyone had similar problems, or does anyone know how to fix this?

 

hmm.... never heard of that.. *shrugs* sorry i can't help there are more 3rd geners on preludepower.org? maybe.com... try them...
