hi i have a 94 prelude with a jdm h22a with a broken m2j5 and i just wanted to know the differences between m2j5 and m2s4 .. and what is different and what needs to be changed or adjusted for either one....and besides that just wanted to know if some one has any after market parts for sale and if they are located here in texas.... and has anyone relubed there sunroof on a 4th gen prelude and how should i do that.....i don't mean to repeat anything if its already been talked about but ive been reading everything all day..... thanks..

 

search for gear ratios in the prelude forum under "archived content"

It's gonna be a direct tranny swap....same mounts, same bell housing pattern..etc

I lube up my sunroof tracks by opening it, spraying a lil WD-40 in the track and then close it almost all the way, then spray a lil more wd-40 in the back pack of the track. Usually makes my sunroof open a little faster.

 

wd 40 kinda suxs and is old school. Use silocon based lubricants from now on. They dimolish wd-40 being that its water based, and water promotes rust anyway in my somewhat educated opinion

 

I will definately take that into consideration. WD-40 lasts about 5-6 weeks in FL until my sunroof starts opening slow again....Thanks for the input

 

The M2S4 has shorter gear ratios.
