Getting ready to do a 3.8 swap in my 88GT. Is there a parts list of needed parts and where to get them? I have read tons of posts on the subject and everyone seems to do things differently with different parts. Some from this guy and some from that and some homemade. Etc. Just looking for a good must have parts list and where to get them. Mounts, pulley, alternator relocation bracket etc.

FieroX used to make the motor mounts. He turned over production to FieroRog. They are excellent quality, heavier than West Coast Fiero mounts, I've used both. Start with the motor mounts. Check my thread, I tried to make it user friendly and document most of what you ask. Good luck.

Here is a fairly decent list of the parts, where I got them and the cost from when I did my swap:



You can read details of my swap in my build thread, starting HERE ON PAGE 13 when my engine followed me home from Alabama.

Thanks for the list very helpful. The motor mounts were only $100? Do you know how much a full set motor and trans mount costs? I am using the Auto that came with my 1998 Buick riviera donor car.

Give FieroRog a call or email him Email: fierorog@gmail.com cell is 319-939-1285 (Copied from his thread). He is fantastic to deal with. He will go over what mounts you need for the engine, and your transmission and can give you a price. The thread for his parts is here.

Here are his lower alternator mount, as well as his combined dog bone / belt tensioner.

Go to the West Coast Fiero site and you should easily be able to see the proper mounts for your application.

P.S. fierorog makes fantastic stuff!

FieroX sold his kit design to IWANNAIRM, not Fiero Rog. IWANNAIRM has been MIA for a while and is not responding to inquiries about his mounts.

Go with Fiero Rog over WCF. I JUST bought a full kit from Roger (Fiero Rog), who is very knowledgable, and his stuff is made well. They're basically brackets that mount up to the Fiero mounts. You might have to buy poly Fiero mounts from Rodney Dickman, so factor that in as an expense. Fiero Rog makes brackets for the 3800, low alt mounts, F23 mounting brackets, and a few other things.

If you want something a little different, James L Brown (JB1 on here) has started making poly mounts for the 3800. They're full mounts, not brackets. He's also a very good source for harnesses, probably the best at the moment. I'd definitely use JB1 over WCF for anything he sells.

If you comb through the forum, you'll find a ton of threads that talk about how poor the customer service is for West Coast Fieros, and even some that detail design issues like weaker made mounts. I had an issue with them myself as far as not answering questions, and no support after purchase. I can't recommend them in good conscience.

Good luck.

Please note that while it may have appeared like an endorsement of West Coast Fiero, I was simply addressing the issue of cost as it relates to the motor mounts. I listed the other parts to give the OP an idea of some items he may not have thought of or considered in his swap. I will just leave it at that.

Poly will not "Shake your teeth out" but will pass more vibration of the engine to the frame. I personally went with rubber in all of my suspension, as well as mounts to for a bit softer / smoother ride.

Depends on your power goals. Stock unmodded 3800SC will be fine on rubber. You start building it for power and the rubber may not be strong enough. The hard part is finding rubber mounts as most of the guys make poly ones. Fiero Rog told me to buy Rodney’s poly mounts for his brackets due to my eventual power goals.
