What about the 3.1 TBI that was in the minivans and Izuzu(sp)? Any info on them? Do they have iron or aluminum heads?

[Anonymous]

iron.

[geoffinbc]

Hey yea that messed... they were FWD blocks were they not? Did they have a FWD motor mount casting and the starter on the opposite side? Hmmmm WEIRD

[Cliff8928]

yes, there were plenty of FWDs with iron heads.... (all of them before 87)

Well no kidding... But what about the ones lasting to 1995 and using TBI?

So I gotta add that when did the Lumina APV start and stop production?

[geoffinbc]

Ok so latest update includes the weird ass APV and also info on the Troopers. They got a 3.1L instead of a 2.8L in 1990 and they used a block with the starter on the drivers side but the same engine mounts as a raditional RWD motor... Is it possible the luminal also used a RWD style block... I also want to know about the Fiero did it use a RWD or FWD block? I know it had MPFI

[Cliff8928]

the starter on the traditional RWD motor is on the passenger side...

What I ment to say was did the lumina use a block with RWD mounting locations but the starter on the even number cylinder side (drivers side) like the Isuzu did. It may be this way since these were the only 2 vehicles to EVER use a 3.1L TBI engine.

Wow I feel so special to drive one
How strong are the transmissions on these things?

[geoffinbc]

Probabally pretty good.

[Cliff8928]

the Lumina van is a 3.1 TBI, then it should have the 3T40 (aka TH125-C)

The lumina vans do however have the typical Gen 2 style timing cover...

As a proud owner of a 1990 Pontiac Transport, I can shed a little light on this one I hope.
It's FWD with iron heads, distributor, TBI, T125 tranny, and from what I can tell is the exact same block as what a Lumina car would've got, just with the Camaro style 3.1 pistons I'm guessing. I know the passenger side motor mount is the style that mounts on the subframe if that explains anymore. I'll take a closer look at it later tonight, and get some pics of the mounts if anyone wants to see them.
Also, on the very early 2.8 FWDs, they had seperate V belt driven accessories, such as water pump, P/S and A/C. There was a Century or something like that at the wreckers a while ago that I was looking over rather closely. The intake on that car looked almost identical to a RWD camaro 2.8 MPFI. Something like a Fiero intake.

[Cliff8928]

Yeah, and those older ones had the waterpump like on all the RWD engines (center of the timing cover), and the HUGE Delcotron alternator (CS144 size)
