Looking into doing an SD4 swap so I'm looking for anyone who has some parts for sale.

Mostly made of Unobtainium, by now. I do wish you luck, however.

The SD4 is a 80's design that never went into mass production. It is capable of making excellent power but keeping it streetable is a challenge. I believe that engine has run its course but they occasionally come up for sale. Jennifer Goss the president of MAFOA owns one and may be able to provide some leads. ------------------

I was able to get ahold of a couple of blocks and heads. basically a nearly complete engine without intake and exhaust along with a marine crank supposedly. I'll have to run the part numbers to know for sure.
If anyone has some intakes like the 4 barrel or two barrel let me know.

Thank you IMSA GT. I do appreciate the response. I've got some Weber-style manifolds, id just need to get the actual carbs however I think I'd rather go the route of EFI but if need be ill find some Webers.

I would check the Marine crankshaft. The flange at the back may or may not fit the Fiero flywheel. I would assume some used SD4 parts are around because the engine is largely obsolete. I've read about a Pontiac drag race car by Nunzie Romano) that ran in the 12's so it is powerful . That video is on You Tube.

Kinsler still manufactures the manifold and EFI for the SD4 if I'm not mistaken. I have no idea about the cost.

The last time i contacted Kinsler they have discontinued their SD4 intakes. Jessel will make a set of shaft rockers though.
I do have a SD4 cylinder head and intake on Ebay.
SD4 specific Parts are hard to come by, but there are capabilities to use Factory parts. Very early duke crossflow heads can handle substantial porting and people have pushed S10 blocks to much higher power levels using marine crankshafts with extra machine work.
Metal timing gears are available. Used cams pop up once in a while, but cores for new grinds seem to he limited to flat tappet cams at the moment. Bullet Cams may have billet cores to use for a roller.
I would think with lots of careful parts selection. And looking for the right parts from the right application, a 150hp duke could be built with reworked factory parts from other applications. There is a video of just this on youtube. Just no parts as used on the fiero. And the intake is probably hardest hurdle to over come.[This message has been edited by FieroWannaBe (edited 08-29-2023).]
