no, really. get on some of the jap forums. the ca18/rb20 motors are some of the most hated out there. weak cranks, mains, stock internals ect.

 

not do dog on you, but why swap in a motor from the 80's with little or no aftermarket support?

 

that's funny, because on the us forums, you are pretty hard pressed to find someone who has had a trans failure.
I suppose if you were trying to put 600 hp through it, it could be weak, but for less then 400, RB20 and KA trans seem to hold up fine.
The only common engine failures i have found mentioned are the crank collars.
I don't know though, I'll let you know in a little while

 

its cool. imo most of the rb guys in the states are fucking dumb. they just think there hot shit because they have a skyline motor. we dont really have much experence with them. not that im saying you are.
oh, ps. he has 411 hp, thats why he looking for a better tranny

 

fucking ditto. i used the same trans in 4 years of drag racing an SR20 setup with 267rwhp to 460rwhp. all those 4 years it was doing 1.8's to 1.4 60fts.


the clutch material and how its disengaged is the biggest cause of trans failures.


but if money is an issue, just cryo all the stock parts.

 

gearing is the same. the difference you notice is the fact that you rev higher in the same gear with the sr20. you could rev 1st gear to whatever speed the bearings seize at.

 

oh. you learn something new every day.

 

69mm stroke.

 

well, good luck with that. I hope you leave it stock so it doesent break, or that you ordered a second motor for spare parts
