what are the exact differences? PLEASE post pics!

tia-

 

okay, got picso f a 93+ rotor housing:
what is different on the 88's?

 

88's have a port for water for the turbo. the FD's rotor housings dont have it.

 

what part of the engine are the motor mounts on?

 

ok, not positive but i believe that the 89-91 are more similar to the 3rd gen housings than the 86-88.

the spark timing is a little different and the egr sytem is a little different, but thats b/t the series 4 and 5 housings

i believe that the series 5 engines rotor housings are interchangable w/ the 3rd gen housings. the only difference is the exhaust ports which are less restrictive on the 3rd gen housings

dont have any pics. sorry

 

This article should answer your questions. It illustrates teh differences between the 13bt and 13b-rew motors.

thanks guys!

 

the fd housings have bigger exhaust ports and no hole for the turbo water, although you could machine that that cating is still there

node: the motor mounts are on the steels

What part are the "steels" and do you know of any sites w/ how-to on the machining of the water hole?
Thanks,
