Fireindc's attempt to build a decent miata. (the search for more torque).

They are not any stronger. They are simply lower cr (you'll notice the obvious lack of a "hump" in the middle of the slug compared to the 99+ pistons) giving you more det resistance. Exclusively on e85 it would be counter productive, but if there's a chance youll track it or flog it on pump gas I'd probably go with the lower cr.

Thanks Vlad. Assuming the pistons/block look good I'm gonna rock the 94 shortblock and pistons for now. It will be tracked, albeit very occasionally, and will possibly need pump gas for longer trips where e85 availability is questionable.
The motor in my car has more miles on it too, so that's a plus for the 94. We shall see what she looks like and go from there. I'll actually have a 99 shortblock laying around I might do a mild build up on as well, then I'll have a semi built motor in the car, and a semi built backup. Or maybe the 99 will hang out for a while in my garage and get fully built eventually. hmmmmmmm.
Going to disassemble some engines this weekend, the 94 BP i'm rebuilding - AND the ej22e that tossed a timing belt and ate some valves. Here's hoping I find some good news.
What do you guys think about a gt2860? Starting to lean towards a real garrett. 2860 should be perfect for my 260-300whp goals, no?

Honest question: If you're shooting for 300whp max on E85, why not go 2560? that'd get you there with quicker spool. Guess the price difference isn't much though to step on up to a 2860 and then you've got more headroom. Amirite?

2560 is on my mind too, but i really like the idea of the top end like dems old setup, or pdextas.
Keep in mind guys, I live at 7200 feet. Barometric pressure is only around 76KPA, so it literally takes 2-3lbs of boost just to get me up to around 100kpa. For instance most people can spin tiny t25's to 14-15psi, mine wont make or hold over 11, no matter what i've tried.
Thin air is a bitch, so keep that in mind. I think 300whp might be pushing it on the 2560 with my altitude. I could be wrong though.

You know guys, I'm just telling you guys my goals are 300 - that way i don't feel like too much of a loser when I come up short. END GOALS would be whatever the 6 speed can handle, because eventually I'll get one. So 330-350whp maybe one day? For now with the 5 speed, 260-300whp is the current goal.

I want close to 300whp UNCORRECTED. I'm sure by the time they add their correction factor on top of that it will say 350whp or something silly like that, but i dont care about corrected numbers. I want actual power

OKay, next serious question for you guys. be honest with me.
MS1 + hi rez code + dw 800's. It runs GREAT on my current setup, completely happy with the ms1 for now.
Now my question is can I run my MS1 off the standard CAS setup and safely make 260-300whp on e85? I'm thinking it should be okay, especially with the help of e85 and its magical det resistance. I'm hoping i can get away with my ms1 for my next step in power. I DO want a ms3 eventually, but just trying to balance my budget for this project and it would be nice to stick with my current computer.

I dream of ms3, sequential fuel, converting to a 32 tooth trigger wheel, getting rid of wasted spark, etc. - BUT that is pretty low down on the priority list right now, because race car. If i had a priority list it would be
1) engine rebuild
2) biggar turbo
3) paint/body
4) upgrade the EMS and work on making everything more efficient and flawless running.
One step at a time .

Pretty much exactly this. My paint job should cost me around $500 + a ton of labor. My dad will paint the car for me, because he has experience doing so and can lay down some nice even coats, AND has all the equipment. I'll be putting in the labor to sand/prime/sand/fill/prime/repeat, so it will mostly be really time consuming. Maybe next summer? I'll see if I can get my motor/turbo setup where I want it first.

My car's going on a real dyno the 26th with upped boost and silly tune. Just because it's $50 for 3 pulls. We'll see how flat my torque curve really is.
That's what i'm all about now, really.

Also I'm not going to lie. I know this is blasphemy, but in some way i really miss the way my old 1.6 had topend pull. The car is just as fast now and has a ton of torque, but the feel of the old setup was fun in its own way with the topend rush. I want that feeling, but i want the car to actually be fast
Maybe I'll still consider a 2560, but I've kinda got a hardon for bigger turbos right now, and want to give one a shot for once.
