I'm looking at getting a DCC9 now, what do I need to buy besides the engine from the links posted above?

Do the 3.4 heads on those remans stay on with the swap or do you have to use the 2.8 heads?

IMO, removing the obstruction in the Y-pipe is much more involved, and therefore debatable as to whether it's worth the hassle/expense. But porting the exhaust manifolds is simple/very quick to do with a bi-metal hole saw, and no re-welding is required.






This also greatly increases manifold gasket life and reduces the chances of the manifolds cracking. Nice picture of what should be removed in the manifolds.

3.4 heads and Fiero 2.8 heads are the same.

3.4 heads are a newer casting and offer more meat around the exhaust ports for running bigger headers if you are going to port the heads, otherwise they are the same.

I recommend the Fiero Store's SSI valves if they still offer them. You get slightly more flow than stock and they will bump up your compression ration slightly since they are flat with a smaller dish to them. (You'll know what I mean when you hold them side-by-side.
They flow better because they narrow slightly at the stem near the valve opening end.

Thank you, I did not know that.
Good info!

Reread 82-T/A's Post Above as he was the first member to response from your thread....

82-T/A:
Couple of things you will need.
- 1 hole has to be drilled in the block for starter re-location.
- a second hole has to be tapped in the block for starter re-location.
- There is a brass fitting which needs to be used in order to re-use the existing oil pressure sending unit.
- You'll need to upgrade your engine from 15lb fuel injectors, to 17lb fuel injectors.



Relocating the Starter is the trickiest part; you (or your mechanic) will need this:

Also, I suggest you read "this link" below which is at the bottom of Rodney's kit:

"Everything you will ever want to know about that swap is in the link below, including all engine info."

I meant like all the covers and manifolds, would the 2.8 covers fit the 3.4 or would I need to salvage a complete 3.4 from a scrapyard for the covers, etc.

YES - the 2.8L intake manifold, plenum, timing cover, rocker covers, water pump, EGR valve, exhaust manifolds and oil pan will fit on the 3.4L.......

EDIT
READ the "How to install a 3.4 L32 engine in a Fiero" link
Better still - send the link to your mechanic.....Especially the appropriate Flywheel/Flexplate (from step 6) as you have a '85. Many 'steps' note '85-'86 OR '87-'88 parts....
