m2k Build! From supercharged 1.6l to F20c
Another season has ended which means its time to tear into the Miata again. Last winter I built up the m45 supercharger setup with a custom wiring harness, new pulleys (~11psi), custom belt setup, air to water intercooler, ID1000's, and lots of engine bay clean up. I was making ~170whp on e85 which is good power for a light Miata, but I was still wanting more. After looking into a K swap I didn't want to use a miata trans with the potential to go turbo and grenade the trans. I happened upon a full F20c dropout (motor, trans, diff, driveshaft, axles, header, accesories, mounts, and the harness) for cheap while I was looking for an s2000 trans. Once I realized how good of a deal it was I made the spontaneous decision to pick it up and swap it.
I've already pulled most everything in the engine bay out and listed it for sale in the classified section.
Currently the motor is at the machine shop getting sleeved and cleaned up after finding out the motor I picked up had a spun bearing (still worth it for the price though). I picked up a new block and thats what will end up in the car. The plan is to complete the swap NA for next season and then turbo to ~350whp the season after that. I'm going to attempt to use my custom harness for the f20c and MS3x. This will be used for daily driving in the summer, track days and autocrosses. Probably no more rallycross once this swap is done.

F20c is the 2.0l but yeah reliable turbo power (chuckles) would be stupid fun in this car. You can talk to acedeuce802 about the ls swapped 99. We've got a pretty crazy garage going on haha.

Yeah good luck with that. Diff mount should be complete tonight. I've cut the PPF and added a turn buckle and tabs to the rear subframe to support the OS Giken diff in the torsen LSD housing.

All of the motor bits are back from the machine shop. Just waiting on the pistons to come back from being coated till I can assemble the block. The head still needs some work unfortunately.

Tonight I got the fuel lines in. Braided stainless supply line with inline filter and a rubber return with the flex fuel sensor. Also got the trans mount bushing sorted out, turns out a Chevy Camaro bushing has the same bolt spacing as the s2000 mount. Ignore the kinked rubber hose, its a place holder at the moment. Also you can see the mounting for the filter and flex fuel sensor are on the opposite side as the OEM mounting because the exhaust will be on that side now.

I'm rebuilding it to stock specs even though I had to sleeve the block. Tuned on e85 on a stock rebuild should be somewhere above 210whp. A supercharger is definitely under consideration given my experience on 1.6l. I think a turbo would be a more interesting challenge, especially when trying to make it reliable on track.

Got the cylinder head back from the 3 angle valve job and installed the valves and springs last night. I'm going to attempt to have the motor completely back together tonight

I sure hope so! I got really motivated and got the motor fully assembled (minus small hoses and what not) tonight. LS coils are just chilling there but that's where I'm considering placing them assuming they clear the hood in the car.

Got the subframe chopped up and motor very close to its final position. I had to create a lot of clearance for the exhaust on the passenger side so that half of the subframe is gonna require more playing to finish up. The motor sits extremely low so a skid plate will definitely be in the works.
