Yes, bikes are very very fast and I want my car to be very very fast too.
Regarding driveline I have a stock 6 speed and 3.9 LSD. It should be ok for a bit. My car's already rolling on 6ULs.
Anyone got any advice on particular parts?

So I threw out some drag race numbers for bikes but of course it is a bigger world than just that. I'm curious, what kinds of lap times do radically race prepared Miatas run at Motorsports Ranch Cresson and Texas World Speedway? I dug around a bit and could not find anything.
We have a couple of psychotically fast guys that race bikes in the CMRA that are capable of extracting about all there is out of a liter bike.
For MSRC on the 1.7 mile course the CMRA lap record is a 1:13.8
For TWS on the 2.9 mile course the CMRA lap record is a 1:41.7

Here's a different idea. Swap in a SuperCharged LS7 @ 8 psi with a T56 trans, plus all the other bits and pieces to make it work in your miata. 575+ whp, reliable boosted miata that can run with almost anything on the streets (including most of them bikes). This may be the cheapest route in the long run. Gonna be a bit unstable at 160mph+ but who cares 
you will be the fastest miata out there.
you will be the fastest miata out there.

edit: just saw you have an 03 so that probably won't work for you

Yeah tell me about it!
I mostly lurk. I joined for the tech and I havn't really posted much since I don't have much to add to Miata specific discussion. I don't even own a miata but I do have a turbo BP powered vehicle. I figured I could stick my head out here a bit and offer my engine to the OP... But you're right, I'm still a Miata noob.

Not to rain a any parades but most people who own a high strung, high hp turbo 4 banger that was intended for the street end up being disappointed in the end result. Driveability issues, cold start problems, turd spool, etc. BTDT. And then there's living in MD and having to deal with emissions unless you have a hookup, loophole, or don't mind uninstalling everything and re-installing it for a 10 minute test.
I'm certainly not trying to discourage you. Just take a step back and realize what you'll have with your car at 400+ whp and what trade-offs/sacrifices you'll have to make to get there. Then decide if it's worth it before you jump in head first.

I had no driveability problems and no starting problems. That's the great thing about turbo cars, you can't have big hp with good driveability.
It would spool at 4000 rpms, so call that bad if you will...but it is all in driving style at that point.

Do you have a 400whp+ miata?

Do you have a 400+whp Miata? I've heard you quote numbers, but have yet to see a dyno sheet. That and your posts indicate you're making wastegate pressure, 12 psi, at 4100 rpm. Is your 400+ on pump gas? Meth? So full boost is at what, 5K rpm?
So how many miles have you put on it? How long have you driven it on the street? How is it at sub 45 degrees (non-Houston weather)?
I'm sure you have quite a bit of experience at what, 21-22 years old. You love the one car you've dumped a lot of money in and modified, but you also won't admit that there are issues and problems with a high strung, high hp car on the street. And please don't tell me there are no issues. You've posted on m.net about tuning issues with the CAS. Sure it's minor, but 10 minor issues add up to a big pain in the ***.
I'm not gonna jump on you any more but the ratio of failed high hp street projects to well sorted out successful street projects is about 1000:1.

No need to have a 400whp turbo Miata. I had one at 280whp 10 years ago and realized the law of diminishing returns in making higher hp with any turbo 4 banger after I owned 3 DSMs (at between 300-350 whp mark), a RX-7 TII (at around 320), and a Suby Forester XT (at 415 whp).
