dr50376272 · 11-05-2010, 06:31 AM

ok, i want to fit a series 6 13b turbo, 13b series 5 5 speed, in my rx4 coupe. right hand drive as i am in japan.

will the 12a turbo timing cover fit the series 6 13b? so i can make it front mount. will series 5 5 speed mate to series 6 motor with series 5 bellhousing? let me know people. also, does 12a turbo distributor fit 13b series 6 motor? allowing me to use a fuel only computer.

thanks guys !

Ok, let me get this straight.
13b rew with s5 tranny in a rx4?
If so the s5 tranny will bolt right up to the motor, and i'm not 100% sure but the front cover off the 12a should fit on the rew and then of cousre you will have to use a dizzy because the rew use crank pickup sensor rather than a cas like the rest of the 13b's.

Yes, but you need to use the S5 clutch

Like i said i was not sure if the 12a cover would fit. Thanks now i know.

Early (S3) 13b front cover will definitely work, but I'm pretty sure there is more than a few 13b REW's using 12a covers.

I think if I recall correctly, the cover will bolt on, but the water pump will not bolt on after the cover is installed (they interfere). I know this is an issue between s4 and s5 and I am pretty sure that a 12a front cover will bolt on an s4.
