MS3 Pro PNP ECU
Shave 20 thou, 3 angle valve job, port/polish
Supertech Dual Spring Kit
Supertech SUB Lifters
Skunk2 Throttle Body
Skunk2 Intake Manifold
Tomei Cams 252 deg intake 256 deg exhaust
Racing Beat Header
New Injectors
~~New Fuel Rail~~ (this one is especially disgusting)
Will be running 93 octane pump gas

I will be ordering the MS3 next week. Curious why the fuel rail is "especially disgusting" I do admit that it's partially cosmetic but is there a real downside?

Now downside, but the stock fuel rail flows well enough.

Well color me wrong AF, fam. :rofl: Apologies to those i misled. I'm not sure why i read that the 185whp variant had a built bottom end.

Its ok. I was 2 years ago when he posted that list. I was just looking at the thread a few weeks ago for his dyno to see what effect the cams had on his torque. Given my recent dyno experience (148whp/133ft*lbs on a "heart breaker" Dyno Dynamics), I was curious where my motor compared.

Here is my motor build list. Roughly about $7k in parts. A friend and I assembled it, so the only outside labor was the machine work on the block.

BP6D short block
Supertech 11:1 (+1mm overbore) pistons
Manley H-beam rods
ARP head studs
Spec Miata head, VVT, short radius machined (pre-2014 rules)
Stock cams and valvetrain
Racing Beat header
2.25" exhaust
Square top manifold (ported to match throttle body and some casting clean up)
Skunk2 throttle body
2.5" Intake (24-26" length)
SuperMiata crank damper
Garage Star pulleys
Stock VVT injectors
DW200 pump
M-tuned fuel rail (single feed) - note, I bought this for cheap this instead of a BP4W fuel rail to swap into a NA8 chassis

Stock fuel rail and hardlines can flow fuel for more then 400whp. Savington has shown that. So spending money on those for a naturally aspirated build is mostly just buying bling and no bang.
