got a eg coupe.. just swap a b18b for a b20b... running a pr4...

problems.... it wont acelerate more than 3rpms.. it keeps bouncing whenever it hits 3....

and second... it idles and runs roughs.. like it missfires or something.. i already replace spark plugs, wires... do i need to replace rotor and dizzy cap....
thanx for lookin

 

anyone???

 

yeah replace those, so is it bouning off the rev limiter

 

thats how it sounds whenver it gets to 3000 rpms. just tried a p61 and itdoesnt do it anymore... my homeboy told me to use a p75..

 

What year is the b20?

 

is says 96 on the bottom of the block...

 

Ok so its an obd2 engine, and how are you running obd1 ecu's.

 

well i was running the pr4 with the jdm ls that is obd2.. and it was running good

 

Do you have the obd2 to obd1 conversion?

 

Btw the ls was probably before 96 which is why it was running obd1 alright.

 

well i got the obd2 dizzy but using a ls obd1 harness,, i got the wires so i could use the obd2 dizzy...

 

no.. the ls was a 98

 

does that ecu have a two stage rev limiter

 

no sir
