Description:
I have a S4 NA 13b and NA trans with a miata gear swap I'd like out of my garage. I did a turbo swap and no longer need these things. Both are local pickup only and are located in Oxford, Michigan.
Engine - As stated this is an 88 s4 NA engine. Engine had about 175k miles on it when it was pulled and still ran when I pulled it. Engine is 99% complete, only reason I say 99% is i can't remember if i took something during my swap that i needed. If i did take something, it's something small. It's pretty much completely stock except for a dual sheave pulley (air pump was removed) and exedy stage 1 clutch.
Engine does run, but I REALLY recommend this be considered a rebuild candidate. It leaked and ate oil pretty heavily. The last 5 years of its service was it being pretty much a track only engine and the poor thing is tired.
Looking for $800 obo
Transmission- This is a NA miata gear swapped transmission that I put together myself, but the input shaft was modified by mazdatrix. Im not sure if it's an s4 or s5 case but it shouldn't matter. Unknown miles on the internals. I probably only put 2 events and less then 100 miles on the trans before I turbo swapped, but I don't recall there being any synchro grinding.
Looking for 600 obo
I don't know what kind of compression numbers it made but I'd guess they are on the lower side but consistent between each rotor face and between front and back rotor. Again that's just a guess based on how it ran last though.
