Those of you who have been keeping up on the Turbo Ecotec Fiero project, know that the big issue is with the transmission because custom axles, tranny mounts, and shift brakets.
Don't even start on the clutch actuator, cause I still haven't thought of that.....
Or have I?
I came up with an idea. The new Pontiac Solstice has an Ecotec, like mine, except because it's a forward mounted engine with rear drive, it needs a RWD tranny. The tranny it possesses is straight from the late-model Covettes! Yep, the Ecotec will run on the same 6-speed that the almighty 350 Small Block attaches to.
With that said, if the bellhousing on the Ecotec is the same as the 350 Chevy's bellhousing, then all I need is the V8archie adaptor plate, and I can keep the same tranny that's already in the Fiero, better yet, move up to a Getrag!
So, can someone supply photo's of either the 350 Chevy's bellhousing, or better yet, the photo of the tranny? I have an Ecotec tranny, but my Ecotec is in pieces, an isn't good to compare photos with right now.
THANKS!!!!!!!!

Its it the same as the LT1 and earlier V8s or the later V8s (LS1). The bellhousing patterns are completely different, and to my knowledge Archie only sells the adapter for the LT1 and earlier.
Here is a small block bellhousing bolt pattern pic. Any good industrieal machiene shop can make something as simple as an adaptor plate. (note: I wouldnt trust the numbers in the pic. just an idea of the layout.) ------------------

fieroturbo, all the ECOTECs I know of have the FWD bellhousing. Yes, you can get a RWD tranny to bolt to the FWD bellhousing if you use a different bellhousing on the tranny. How do you think the 3800 in the F-body mates to the manual transmission in that car?

I thought archie sold adaptor plates for the LS1's and LS6's too? I mean, how else would the Corvette motors work in Fiero's?

The LS1's and 6's are not really the same small-block as the LT1 and 4. Namely, they use a very different, very specialized dry sump oiling setup, and the pan has been causing problems with swaps into other cars. That, and different ignition system (one coil per cylinder), etc...
FYI, the last I heard the production Solstice will NOT use the F-body 6-speed. (or Vette 6-speed) It's an Aikin (sp?) transmission. I believe that's from Saab?

Yeah, Aisin tranny, sad to say, it's the tranny from the Chevy Colorado manual model, and that has a 5 cyliner motor on it.
I think that's what they had to do to cut the price under $20,000 for the car. I really do hope though that they make the 6-speed 240HP supercharged Ecotec Solstice at some point. That would be sweeeeeet!
Reguardless, the Solstice can fit a 350 Small block in its engine bay, so heads up archie, you've got another Pontiac project ahead of you.
Now, if this aisin tranny is from a Saab, then I'm in luck. The Ecotec is used in Saabs as well, so I may very well be able to use the archie adaptor here.
And BTW, that picture above helps me in no way at all. I need a photo of some sort. Thanks anyway though.

Ok, after some tedious research on j-body.org and yahoo, the verdict is that the Ecotec (automatic) racing teams use the 4T65-E tranny that is matted to the same 3.8SC motor cars (you know, the donor cars for 3.8 supercharged fieros?). How they do it, is with an adaptor plate.
Same deal with matting a 350 chevy to that same tranny (like the concept car for the new FWD LS1 SS Impala, that isn't going to be made). So that means that the starter motor positions are the same, which is sorta why I strayed away from adaptor plates for this conversion in the first place.
But that still doesn't answer my question of whether the 350 and Ecotec bellhousings are the same (and apparently the late model 2.4L Quad 4's).
From looking at Bryson's pictures of his Quad 4 project, the bolt holes look very similar, except the lower front hole, which is way off by at least 4 inches.
ARGHH, ANYONE HAVE PICTURES OF ANYTHING AT ALLLLLL????? Getrags, 350's, stock isuzu's, anything.

Can't help ya with the bellhousing picture, but... If the racing teams use the adapter plate to use the 4t65E to the ecotec, why not use their same adapter plate and just bolt a 5spd getrag to it? Then you don't have to worry about clutch hookups..
