Thinking about a 3.4 DOHC swap
Ok I have thought about a 3.4 dohc swap for awhile, and more recently have been hearing alot more about them. I think that a 3.4 would be perfect for building a well rounded fiero. So does anyone want to help me out by giving me some information about the swap?

Contact Erik at Pfiffle, he will build you a plug and play harness.
Buy an engine.
Buy a 88 Fiero.
Take the 2.8 out.
Put the 3.4 in.
Plug the 3.4 in.
Start the 3.4.
Try to keep the back end straight :thumbleft:

I did the swap, its really very easy. I did a small build thread, and many others have over on Old Europe. If you decide to do the swap I'd be happy to give any advice.
It was a fun engine, woke the car right up. I almost wish I would have kept it, but I came across a N* for a price I couldn't refuse.
Here is my build on Old Europe. Not really a build, more of a progress report.

Sorry, I have biases. I said that becuz the swap is easier, the 3.4 will bolt on the factory mounts, and if you had the money, be honest, you'd choose an 88 car (Besides Indy's and other special ones of course).donk_316 wrote:Id skip the "buy an 88" though.
otherwise yeah what he said.

actually i like the pre-88' because parts are cheaper - more readily available - there is more aftermarket support - etcaaron wrote:Sorry, I have biases.

I'd avoid the swap, though, because you'd have aaron giving you "advice" all the time. That would get on my nerve.

On my 87GT (and other pre 88's I'm sure) the motor WILL bolt straight up to the Fiero's 3 mount system - tranny has two, and the L shaped 2.8 bracket will bolt straight onto the 3.4. Matter of fact, I tossed it in on the stocker mounts, and didn't like how it sat, and how loose it was.
I did mod my mounts so I could use thinner, tougher, cheaper Dodge truck mounts. The U shaped front mount on the 88 supposedly bolts to the block on both sides, but the way I see it, the rubber mount would break before the block or L bracket so I don't think its really necessary.
