Default 13b series 6 and 5 speed help

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.

Zack.

Yes, but you need to use the S5 clutch

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.
