I did a search here for some info on 2.8 V6 swaps and I am no good at putting in search criteria as I always end up with bizarre answer pages...... Having said that, I am looking for info on a 2.8 V6 swap in an '86 GT 4 speed.
I might purchase an '86 GT as a small side project but it has a thrown rod bearing by the sounds of it. I can get a remanufactured 1988-89 GM 2.8L FWD for a decent price.
Will this block fit into the '86 to put the Fiero accessories back on? If yes, besides grinding off the external weight on the Fiero flywheel as it will most likely be an internally balanced engine from this year period, is there anything else I need to do? I have swapped out a Blazer 2.8 before and swapped the starter motor and other bits and pieces over but I was wondering what the deal is on later model year FWD 2.8 V6's.
Thanks Don

I got some more info and a couple more qustions......
The 2.8 V6 is FWD, MFI, flat lifters, cast iron heads, dist ign. internally balanced. As I suspected, the 2.8 is internally balanced, the distributor would be swapped out for the Fiero, the MFI swapped over to the Fiero intakes and MFI. I believe the '86 has cast heads as well, so I don't think there should be a problem to swap it out. Just a matter of making sure the bolt pattern is correct for the trans and motor mounts. Thoughts anyone?
As for other available engines;
I can also get a: 1990 31 FWD, 91-92 3.1 RWD, or 91-94 3.1 FWD.
I did not get specs on these ones. I just wanrt to get a cheap V6 into the car to play with it until the snow falls and then probably sell it in the Spring once my Ferrari kit is complete and on the road.
Al these engines are avalaible for $499.00 CDN remanufactured. The place I am talking to bought out a company's inventory that stopped rebuilding gas engines and started focusing on Deisels. Normally the rebuilds are going for around $1500.00 - $1600.00 up here.
Any help would be greatly appreciated.
Thanks Don

I thank you very much for answering. The internally balanced flywheel I remember from my last 2.8 swap from a Blazer but I was not sure if everything else would match up.
Looks like I may well buy the car now that I know I can get a rebuilt engine cheap.
The only thing I can think of in addition to the other comments is that you'll probably need something to block off the crank position sensor hole that's likely to be in the side of the block. An old sensor will work, or you might be able to find a freeze plug that size. On the flywheel, don't modify your old one by removing the weight unless you have a machine shop that can spin-balance it at high speed. It only takes a very slight imbalance to trash your main bearings and crank. It'd be wiser to purchase a new one IMHO.

Swaping would be the same proccess as swaping in a 3.4L from a 93-95 camaro/firebird. compleate swap coverage can be found here. 3.4L pushrod Swap (lots of pics)
BTW the flywheel you need can be found at Checker for $40 88Fiero V6 flywheel.
If the 2.8L came out of a FWD car then the starter won't need to be relocated. Just a minor point in the scheme of things. The RWD ones will need it relocated (the 3.4L is originally a RWD engine)

So that nobody following this thread ends up locating the wrong engine, a related point of clarification is the 3.4L engines mentioned here are from the `93 to `95 Camaro/Firebirds, not the `92 to `95s.
