I have a 88 TII 10AE. NewB trying to understand which used engine parts and accessories are interchangeable within the 87-88 TII range.

The most recent part in question is the water pump housing.

Relevant information appreciated!

im almost positive that all the 87-88 engines are interchangable and all the 89-91 engines are interchangable

Are you saying that it doesn't matter whether the engine is a NA or a TII, most of the engine parts, excluding fuel, are interchangeable?

He meant TII.

Sir Rupert Hobo

everything should be the exact same. i'm pretty sure mazda wouldn't have put much thought on how to improve the engineering/cosmetic duties of the car from year to year, but rather from series to series.

all except for the earlier models having low imp. injectors and what not.

yes i was only talking about the tII engines thanks for cleaning that up for me derangedhermit sorry for not saying it clearly

Chuckles

To summarize, if I stay within the S4 TII arena (87-88), most all of the engine parts are interchangeable. From reading the archives, posts, and Rotary Resurrection's tech pages, I remember the only exceptions are the ECUs and the injectors (different numbers). Are there others I should be aware?

Thanks to the guys who responded. I appreciate the info and will continue to read and learn from the posts. Was able to buy a 87 TII water pump housing for my 88 TII AE because of your responses.
