Back to Drivetrain.
Contents
Build Plan
- 94-97 or 99-00 Miata Block (in theory identical)
- 99 Miata Head
- Displacement?
- Pistons?
- Crank?
Do we want to try to do this ourselves or just pay Flyin Miata a metric asston for one of their absurdly expensive builds?
Parts Research
- Block: 94-01 blocks are effectively identical for our purposes (piston change). Trying to find an affordable 99 full motor is becoming difficult.
- Head: Maybe just look for a 99 head and put it on a 94 full motor?
- 2002 Oil Pan: 207$ from Mazdacomp, 10-400
- 2002 Oil Pan Support Plate: Asked Bob what the support plate is -- if it's the baffle plate (10-406A), then it's 66$
- 2002 Oil Pump: 198$ from Mazdacomp
- Eagle H-beam rods: 291$ from random sketchy place
- Carillo A-beam rods: 850$ from 949
- 949 Racing Rods: 329$
- Wiseco Coated Pistons: 796$ from FM (exclusive), includes rings/wrist pins
- ACL Main Bearings: 82$ from FM
- ACL Rod Bearings: 51$ from FM
- ARP Head Studs: 117$ from 949
- FM ARP Head Studs: 167$ from FM
- FM Head Gasket Kit: 215$ from FM
- Rebuild Gasket Set: 201$ from Mazdacomp
- Inconel Exhaust Valves: 33$/ea (264$/8), 1mm oversize
- Intake Valves: 22$/ea (176$/8), 1mm oversize
- Supertech Valves: 18$/ea (288$/16), 1mm oversize
- Mazdacomp Engine Mounts: 35$/ea, NAY1-39-040
- Supertech valve springs/retainers/seats: 314$ from 949
- Supertech shim-under-bucket lifters: 359$ from 949 + 5.5$/shim
Bob Bundy's Build
400+rwhp w/a big turbo
- 2.0L FM Stroker
- 94 Block
- 2002+ Pan/Support Plate/Oil Pump
- 99 Head
- Ceramic coated top wiesco pistons. (now standard at FM)
- Oil Squirters Blocked off. (much less oil consumption haven't found a downside and they don't fit with the new pistons anyway now standard with FM builds)
- FM now has Inconell exhaust valves. I think these are really needed on a track car. I've burned exhaust valves twice I think related with over oiling oil control rings using squrters and after market pistons. I don't have inconel exhaust valves yet though.
- ACL race bearings
- Stock cams
TrackDayHookey's Build
420rwhp with a Rotrex centrifugal supercharger
- 94 block, 99 head.
- 1mm oversize Supertech pistons, 8.6:1, but with deck shave and head work the engine is about 9:1.
- 1mm oversize Supertech valves (both intake and exhaust) and Supertech springs (the relatively low seat force version as I don't plan on revving past ~7500).
- Rods from 949Racing.
- 1000 cc injectors.
- Integral "stage 2" intake cam - a little more lift.
- I ported the head. I might even have made it better. Valve deshrouding, clean up the bowl, match the head ports to the intake manifold.
- Custom intake manifold.
- 100 octane gas
Injection
What injectors will we need? 1000cc or can we get away with less? I got 392whp on the Alltrac with 880cc injectors without coming too close to maxing out.
Alternator
Any weight or efficiency gains to be had with some sort of aftermarket alternator?
