Doubt there is a 3.0 bellhousing for a mitsu trans since the mistu ended before the 3.0 started.
If I remember correctly, with that intake manifold they achieved 114% volumetric efficiency, that's insane on a N/A engine!
Actually there is, 1986-87 aerostars were sold with a 3.0 and a 5sp TK trans
and the T-K uses the same bellhousing as an FM145.
So IF you can find an '86-87 3.0 5sp aerostar you could get a bellhousing.
it can be made to fit. either an adaptor between the engine and trans, or you need a vulcan bellhousing off of an FM trans out of an aerostar.
The Aerostars in '86-87 ONLY used a TK trans.
Until '89 there wasn't a 2wd FM
for 1988 the RARE 5sp Aerostars used a Mazda M5OD-R1
(I have two of the unique top covers used on the
aerostar version of the trans)
Frankly I'd scrap the FM145 and look for a '93-up Mazda M5OD-R1 trans.
It'll definatly stand up to a SHO engine.
But then again there's another engine that I honestly think would be a better choice for a Ranger that everyone ignores...
The Split-Port version of the 3.8 engine used in Windstars and Mustangs.
That engine suffers NONE of the problems the original 3.8 engine had but makes 215hp, but at a MUCH lower rpm than the SHO engine.
Granted it doesn't sound exotic like "SHO" and doesn't look as sexy
compared to the SHO's "nest of snakes", but....
