how can i tell..?

O.k. was just reading some of the forums that been up and just getting tired in trying to find one, so i just decided to join.. My question is..

I have a 91 civic si, and found out a month later that it has an hf(i think crx) now i was wondering, how can i find out what tranny is in there and ecu.. it doesn't have that dual piont injector set up, looks like it has the bigger intake on it..the car does move though... well hope i can get some feed back on this....

by the way, went looking for the person that sold it 2 me but after very bad phone conversation i had with him, went to his home but the dick had moved on me....

tranny code is on the front of the trans where it mounts to the block. the ecu is under the passenger side carpet and the code is on the side, if its a Si ecu it will say pm6

thanks will check tomorrow..and after i check the tranny, where can i find out what kind it is..?
Is that your car..?

yea same as hybrid said, as for the tranny it might be hard to look at it from the top try jacking up the car and securing it so it squash you, look on the pass side and look by where the motor mount

it should read some numbers, like
SI - PL3/X000 X=any number<-if it reads like that then its an SI tranny if it has a letter before the N#
its an HF or DX - PL3/A000 or PL3/A100. let us know what you got.
