1.6L build
Hey guys. New to the Miata scene, but not to the FI 4cyl scene.
I just picked up a '91 BRG Miata in amazing shape. Owned by an elderly gentleman who babied it and kept it in perfect condition.
I want to upgrade it with the eventual goal of a fun autocrosser (I don't care what class) and weekend canyon-run type car. I'm looking for some serious advice, so I'll start with what I know...
YES I realize a 1.8L is a better platform to start from. I have an '03 engine and 6sp tranny at the local salvage yard for $2,000 I'm considering.
YES I realize the 1.6 rear end won't hold up. I already bought a torsen, driveshaft, and stub axles.
As far as power goals, I'd really like to hit 200whp, maybe 230whp at the most. I just sold my 300whp STi, and I know that a 200+whp miata will be really quick.
My question is pretty much this... Since I'm not looking to go past low 200's for whp, is it worth my time to swap out for the 1.8L? I know the spool will be faster, and it'll have a little more torque down low, but I could really use that extra 2k and the time and other materials required. My budget isn't very large for the power-side of things. I want to leave enough room in my overall budget for suspension, wheels, tires, etc.
I know this has been talk about a thousand times, but I'm hoping that my situation is a little unique due to the modest power goals. Thanks, sorry if this is in the wrong section or it's redundant.

FYI, 250whp on a Dynojet is "just right" in these cars if you ask me. I'm at 254whp on a Mustang and its a little excessive.

Ok, I get it. I'm sticking with the 1.6L. That being said, I just tried my first leakdown test, and I think I got pretty good results, with an average of about 2% loss. For a motor with 110k miles, I think that's pretty good. I'm going to go ahead and do the clutch, flywheel, rear end, and then go mspnp w/electronics-less voodoo 2560R kit. Sound reasonable to everyone?
