Well, I'm getting ready to do a 3800sc engine swap into an 85 Fiero. The engine is a series I from a 95 regal. I want to use a manual transmission and would like some input as to what transmissions I can use and what my best choice would be. The car will mainly be used for cruising ( not much over 65 mph) but I might do some solo racing and possibly some road racing (nothing over 110 mph). For solo racing and road racing I will be running a 195/60R14 tire.

If you have some tried and true experience with different trans. ratios, I'd appreciate your advice.

Getrag is the best trans. WHY are you using 14" tires ? they don't do "anything" for Handling, & you are limited to what you can do for brake upgrades. Why not 16" or 17" with low profile sidewalls ? I personally don't like "Bigger" than 17" (gets "Hotwheels looking"). just curious

I did a limited amount of solo racing a few years back (most races were 1 1/2 to 2 hrs away) and bought a set of 14" stickies for my 2.8 car. I don't intend to do a whole lot of racing with this one for the same reason, and would rather spend the money on show.

Just curious. Why did you opt for a series I and not a II or III?

I bought the wrecked Rivie, pulled everything I needed and sold the rest. I have $100.00 invested.

I have been searching build threads and am confused on what I need for a flywheel and clutch. Will any year 3800 camaro/firebird flywheel work? Best clutch?

96 to last year of that model F body 3800 manual flywheel machined down to .840 or .820 as some like and balanced to match the auto flex plate your series I came with. Dan

I have done some research and SPEC makes a clutch for this application I believe you can use there Aluminum flywheel ($$$$$) or Like FieroFlyer said use a 96+ 3800 F-Body flywheel turned down to .8xx" but what I'm not 100% clear on is can you use a 96+ F-Body Pressure plate along with a Clutch disk for the trans you choose to use? If your on a Pick-n-Pull budget that may work, but like I say, I'm not sure.

------------------
1986 SE 3800SC/4t65eHD (12.871@104.96) I'll Sell it if you like
1985 GT 3800SC (swap in progress)

Thanks to all for the input. I did check into the alum. flywheel. Nice but not really necessary for the main purpose I have for the car. And I'd rather spend the money on other mods. I'll have to check the threads again on the Spec clutches. Seems I read that the Spec 3 didn't hold. Don't know the difference between a 3 and 4.

Spec 3 OR Spec 3+ willl hold for the power you put down. Series1 not as powerful as the Series II hp wise.
If the 3 is not holding, there are more mods done than it can handle and should beupgraded to a 3+ or better then.

I have a similar swap in the works. whats the big difference between the F23 and the F40 in terms of performance and the ease with which they can be swapped in?
