I've been wondering if a 1.8L miata transmission will bolt up to a 2.0L FS-DE out of a 2002 Mazda Protege.

Based off what I know about my previous work on Protege's:
-an older BP (protege) transmission will bolt up to newer FS engine (if you swap the flywheel/clutch) (????)
-The BP block in the older protege's was the same block used in the miata (with minor changes and a different intake of course)
-Therefore a newer FS-DE protege engine should bolt up to the bp miata transmission...

The reason why I'm considering this is because I have several FS-DE engines in the garage, one of which is already built and boosted...
and I just picked up an underpowered 1.6L miata.

If anyone can measure the bolt distances on the 1.8L transmission, I'd greatly appreciate it.

AC : 11 1/2"
BC : 6 1/2"
BD : 12 1/2"
AD : 13 1/4"

Starter bolts
S1-S2 : 3 1/8"
S2-S3 : 3 1/8"
S1-S3 : 4 1/2"

Fabbing up an intake, exhaust, wiring, etc isn't much of an issue.
I won't even bother with the swap if the bellhousing doesn't mate up to the FS-DE.

Thanks

hmmm...let me go digging around in the garage tomorrow. I've got an FS plate like the one in the picture and a BP block laying around. I'll get back to you.
