Do any of the 5 sp FDs fit in the 4sp manual of the Civic Std?

Also, what's a good site to find all the tranny ratios for the 88-91 Civics? Thanks.

 

I shouold be taking out my dx motor and 5spd tranny and droppiong it the 90 dx hatchback that came with only 4spd.

 

I'm keeping the 4sp but looking for a shorter final drive and was hoping one of the 5sp FDs could be used??????

That is what I have found, I think most of it is thanks to Mista Bone.

 

dave, check you IMs.

 

I must for the class (SCCA ITC).

Maybe the Si 4.25 will fit?????????

 

Dave, as long as you use the ring gear and matched countershaft, any of the L3 FD ratios will fit. Don't change the diff, just the ring gear that way you won't have reshim the diff.

2.93, 3.25 (what you have now), 3.889, 4.058, 4.250, 4.437 (Rover) 4.73 are the ratios that are available.

You could get a 4.73 from OPM or Houseman. Jamie can make you a 5.00, if you have the $$$$.
I've not read the GCR rules for IT classes.
