My 1988 4cyl was having some compression issues about 4 years ago. I originally planned on doing a LT1 swap, then decided on a 3800SC because it seemed easier and cheaper. Then I decided to buy a house instead.

The car has been covered up and parked on cement for a while now. I start it occasionally, but I have a feeling it's time to get her going again. I'm trying to decide on what to do with it. At this point I really don't want to do a v8 or a 3800 swap. I would just like to have a car that I can enjoy on weekends. I'm hoping to buy a Trans Am this summer so that can be my "fast car".

But I have to do something with the Fiero, because sitting isn't helping anything. It's a 125k mile CJB ttop car, with Mr Mikes seats, spoiler, formula/gt wheels, so it's worth keeping. I'm considering rebuilding/replacing the 2.5l or preferably putting a 2.8l in there instead....maybe the 3.4. I think those options would be easier and more affordable to do than something totally custom.

What's your opinion? Does anyone know of any 2.8L engines for sale close to Buffalo NY? Ay feedback or opinions would be appreciated.

3.4/4T60 is a sweet combination......

I wouldn't waste the money rebuilding a duke. A 3.4 from a Camaro, especially if you have a manual tranny, would give your Fiero a nice boost with plenty of pep... and it's one of the simpler swaps.

You guys are right about the 3.4. That's probably what I should go with.
My car is an automatic right now. Is the 4T60 a hard swap? I'm assuming I would just need a computer out of a v6 auto car, right?

The only thing the 4T60 needs from a computer is a signal to lock the TCC... other than that it's still cable and vacuum controlled. So yes, it could work with a stock Fiero automatic ECM, but requires adapting the VSS signal and inverting the TCC signal (the TCC works differently in the 4T60 than it does in the 125C).

The swap is a bit more involved with an '88 because the location for the rear trans mount slopes up differently where normally another slotted hole is made on the pre-88 cradle...

Pre-88

This is what has kept me from looking at the 4T60 swap over the years (especially when I really wanted a manual anyway).

Make sure you post when you're ready to begin a swap. I'd be happy to help, but have never done it. (Yes looking for free experience LOL)

Guys, thanks for the input. If everything goes as planned, I will have a low mileage 88 v6 drivetrain. Which should be a easy swap. For the price, I couldn't say no. I just lucked out on this one haha.

It feels good to be back in the Fiero world after being gone for years.

Actually, I plan of having a mechanic friend do most of it. He has the right tools and skills to get it done quickly. I might be doing some of the work also, and your welcome to lend a hand too!

It's always good to have a mechanic friend!
