run the stock motor, or build it?
#22
he told me over the phone that most of the supercharged miata people in town don't like anything lower than 9.0:1 compression pistons. He didn't try to push me either way, but I'm kinda worried. I also don't know how many people actually tuned the car properly with adequate ignition advance in off-boost rpm.
Seriously, you have two choices when making decisions. Listen to what other people say and trust them, or do your own thinking and tell all those with opinions to F-off. You can't keep standing on the fence and expect to make everybody happy. There are compromises: deal with it.
You'll be plenty happy using the rods and pistons you already have, and letting that dude build your block. Do it. Case closed. Or ignore me and do whatever you want, but then quit asking for opinions.

You can always get those 13:1 JE pistons in m.net classifieds
If you're afraid if it dying, run it stock 1.8 w/ turbo for a while until you are either comfortable with it, or until you kill it. And go from there.

2 things, (1) it has to be done by someone smart or you'll f it up, and (2) the cool kids say you need to nitride the crank afterwards.
I'd also be curious about impact to the oil pump gears.

Run the stock motor now and turbo that bitch! Run a lower 12psi and keep an eye on your temp/pressure gauges on the track.
Then, pickup a block on the side and build an engine in the interim so you can have something to obsess about. Just get you car freakin' turboed already!
Fear is paralyzing you man. Even the most well built engine can fail. Granted they run on the bleeding edge, but I'm sure there is a hell of a lot more precision that goes into an F1 engine and even they die sometimes. Heck, what if you built the perfect engine and you crash on the track or some idiot crashes into you, how are you going to prevent that? Avoid the track altogether?

For the love of all that is holy, do SOMETHING already.
Personally I think you are crazy for bothering to build the motor at the power levels you are talking. But since you already have the parts and the engine isn't in the car, you'd be a foold not to do the work now. Why R&R the engine more than you have to?

Everything has been waiting on motor availability. I'm itching to do something so I can do some track days while its nice, and not 100* in 4 months.

I want to know I'm going to make it home on the 4-hour drive home from the track, if I didn't blow it up at the track, and make it to work on monday.

If you're going to open the motor, throw some Belfab rods, Weisco pistons (9:1), and billet oil pump gears in. That way when you're ready to spin the motor harder, you just have to swap valvetrains and you're ready for 8k.
