Ever figure out the shifting or temp gauge? Mines doing the same thing...

 

sorry to bump and old thread but I have the F20B swap in (very similar) and I am having a problem with the idle dropping ans stalling when I rev the rpms at all and let out on them... this also occurs while driving and coming to a stop.... I have a primary O2 sensor CEL and I replaced with a non-ulev sensor denso but it didnt change the idle and it still had the light. this weekend i am going to check the voltage coming to the plug but jsut seeing if anyone else has had this problem.

 

I'm having a problem with a CEL for primary O2 sensor heater circuit as well.. Did you ever find a fix?

 

jus looking for some info on torque specs i did a H23A blue top into my 99 CG sedan 5 speed

 

What kind of torque specs? You just treat it like an H22 swap for the most part

anybody know if a '98 lude's automatic transmission will work on my '02 accord se coupe it's a 2.3?????? please . oh yeah and if it does who knows how to to wire it up ?

 

ok I have a question, so if I get an h22a4 and the automatic transmission that goes with it from a 98 prelude, how do I hook up the transmission wiring??? in a 2002 accord se coupe 2.3 auto.

 

hardly anyone comes in here anymore. you cant just drop in a prelude at trans. but f23 and h22 have similar bolt pattens. just use the stock trans or do a 5 spd swap. ive done at least 2 auto to manual swaps and 3 f to h swaps. manual is much more reliable long term.
