i just purchased a 90 crx hf for parts, can i swap the final drive from my si tranny into the hf tranny, just trying to buy time until i get a new transmission

 

If you swap the final drive you have to swap the main shaft also.

 

thats right...^^^^ dont mind me asking..where in louisiana do you live in?

 

not true - to swap only the final drive, you need to swap the countershaft (using the HF gears on the Si countershaft) and the Si ring gear onto the HF differential, not the mainshaft

 

well damn i guess im livin with airplane gears for now...

 

Lol I know the feeling, I can do 70 mph on the highway in 3rd and still be under 3500 rpm.

 

I'm sorry for giving the wrong information, I'm not sure how I confused the mainshaft with the countershaft. If you ever need correct information, you can always count jlicrx, he is very good at answering a broad range of EF questions.

And to thiendegigolo, I live in Ruston(northern LA).

 

why dont you just use your "si tranny"?
