will a 88-91 si tranny bolt directly to a dx motor? i've searched and couldn't find anything,sorry if already asked.

 

yes it will

 

what year DX engine? will you be using the old flywheel?

basically:
88 flywheel / clutch will only work with an 88 tranny
89 flywheel / clutch will work with 89-91 tranny
90-91 flywheel / clutch (Ideal) will work with 89-91 tranny

 

yea it's a 90 hatch i'm tired of the 4-speed i need a 5-speed bad no i'm going to get an aluminum flywheel in place of the stock one

 

then definately get the 90-91 flywheel, 90-91 clutch kit, and 89-91 Si tranny. You can ID this tranny by the stamp on it that says:

PL3
3000

are you getting the tranny for freeway cruzing or performance?
5th gear in an Si tranny is the same as 4th gear in a 4-speed.

 

i'm basiclly getting it for both, i'm completely rebulding the motor and getting everything my hard earned money i can get for internal mods (my main concern) with some boltons. some of the kids in franklin will pay anything for a car as long as it's an honda.... 's to me on that one,i just want to get as much hp i can out of the dx motor

 

good strategy... you can always add the bolt-ons later

the head work is where you'll get the most gains internally, focus there. The Si cam and valve springs will fit, as well as aftermarket versions made for the Si. I wouldn't do the cam without the valvesprings though.

do you have the mpfi swap yet?

just my $.02

 

i'm going to start on it once i get the tranny so itll get done in 2 days at the most
