Hey guys, anyone want to start up a thread with a database of different drivetrain combos that people are using? Post up what you use and how it's mounted(kit or homebrew). Also, please post up how you use your car and if you have had any issues with your setup. The more info the better. Pics would be great.

This will help people decide what to run for their future swaps (me included).

1999 NB Miata, V8R conversion, GM 480 HP (415 rwh) crate motor, T-56, 3:42 Getrag, 16 inch Konig wheels with 225/50 T1R's on them, V8R tubular control arms, Hard Dog deuce roll bar, FM's big brake kit, Frog Arms, Racing Beat nose. Pictures are posted on this site. This car replaced a 1989 Testarossa and I enjoy the MX-5 much more than the Ferrari. (for starters you can walk away from it in a parking lot and there are no $5,977.00 services due every 15k miles) This car is just used to blast around the curvy roads of northwest Louisiana and east Texas on nice days. FM did the conversion and many folks that see it, say it looks like it came that way from the factory. FM's quality of work is incredible. Everyone does not have the time to do a conversion but still want's it done "right". This car is so much fun to drive that it's hard to measure. The only change we will make on our next conversion will be to use a GM 638 HP LS9 instead of the 480 HP LS3. Wiz.

I’ve tried to improve upon the “formula” with every build. The first was a just to see if I could do it (and save up the $$$ beforehand), the second was a refinement in the suspension area mostly (the AFR heads and other improvements came after I sold it), the third was an opportunity to prove that I could eclipse the power of the first and gain better mileage than a stock Mustang as well as refine my wiring and AC systems, the fourth is an experiment to see if I can reach LSx levels of power with the 331 and incorporate a few other minor systems to make the car more track worthy (oil cooler and Wilwood brakes).

Out of the three that are already built the third one (white 1990) was the most “balanced.” It could hold its own on the track against modern Corvettes and S-2000’s but could also sustain a high enough MPG and level of comfort for true daily driving. The first one was a bit rough and the second is a bit more track-oriented. I’m hoping with the fourth one will have the “grunt” of the second with the refinement of the last. I’m also hoping that the only car that did pass me at the last track day (in build #3), a late model Z06, will have a little more trouble this year doing so with the 331 Laguna.
