160 HP ( !! ?? ) ! There is no normally-aspirated 2.3 that's putting
out anywhere near that figure! More like 96 HP if I recall.
Your easiest bet would be to upgrade to an '89-'91 Trooper with a GM
2.8 V6 already installed. This V6 puts out about 125HP stock but with
bolt-ons you can probably get closer to 140+HP out of it. And then you
have the option of installing a larger motor, a Goodwrench HT 3.4 or a
3.4 out of Camaro/Firebird. Bolts right up to the 2.8 tranny and the
biggest mod you have to make is to drill the block on the left side for
the starter since Isuzu used the GM FWD 60 deg bolt pattern for their
MUA-5 tranny on this rig.
The 3.4 can make between 160-200 hp depending upon modifications. Way
more performance than a stock 2.8.
Conversely, if you were to apply this motor to your '87, best bet would
be to find a rusty or wrecked 2.8 Trooper so you could pull the tranny,
mounts, accessories, etc etc off of it. You'd have to modify your
motor mounts somewhat, and you could use a carbureted intake manifold
off an S-10 (or use an Edelbrock or Offenhauser aftermarket manifold
and Holley 390 Cfm 4-bbl or 500 Cfm 2-bbl).
One caveat on your '87, if it has rear drum brakes it does have the
weaker rear-end, on '88's and up the entire drivetrain was beefed up.
So a Hot-Rod V6 might be a bit much for the older-style rear end.
Anyway, lots of information on the swap at the following Isuzu sites,
don't waste your time with Spammers and misinformation at this site.
