Use=Everything quite literally
Money=In the long run endless so not a factor.

No just because I am new to this forum does not mean they can be rude! Power varies way to much to be a comparison. Boost is more accurate because it accurately measures the maxium pressure that the engine can handle.
A car can have 500hp and 400hp but be only running 30psi. Both of which would blowup at that same psi but hp.

Maximum pressure- Care to define this loose term you just threw in? Feel free to be more specific in term of PPP, MBT, etc in a SI engine.

Cmon, people have made legit attempts at helping you out but seems like you need to help yourself out for now. You need to be more realistic about your goals..
This is how I read this post:
I want to make the most power but not too much power
I want to use my car for everything and anything
I have no certain budget, but if I did it wouldn't matter
It should read:
I want to make upwards of 200whp, with room to grow
I'm uncertain of what I will do with it, but def not -rifting
I'd like to have a quality build, but need ot cut corners in order to stay under 5k
Otherwise, stick with my very simple and specific answer...41-43lbs

In my time around miatas, IIRC that is, I don't remember ever hearing of anyone talking about 30psi and so on. I do believe there was a guy on here though that had a built motor and a larger turbo boosting around 25psi.
Don't be so concerned about rudeness over here. Lots of these guys on here are REAL LIFE tough guys. They are ******* dead serious with you dude.

you should be asking how much power your motor may handle (5 speeds don't break at 15 psi) not how much pressure

Wrong. You've been here like a week and you think you can tell us how to run our forum? **** off. If you want, you can eat a piece of humble pie and understand that everyone here isn't a total ***, but when you mouth off to senior members you can expect a serious bitchslapping. We all know a hell of a lot more than you do (you've proven that categorically in this thread). You have two options: Apologize and we can all nicely explain to you why you're wrong, or keep acting like a dick and we'll run you out of here faster than Hitler ran the Poles out.
Wrong. Power is the only comparison that matters, and I'll explain that after the next time you're wrong.
Totally wrong. Boost pressure is nothing more than a measurement of restriction in the intake manifold. What actually matters is pressure in the cylinders, which is directly related to torque.
Totally, utterly wrong. Motors are designed to take a certain compression pressure, which is directly related to torque. It really doesn't care what the pressure in the intake manifold is, which is all you measure. Boost is actually a pretty arbitrary, bullshit thing to measure or base power readings off of; this is demonstrated quite well by the fact that y8s makes 257whp from 9psi, but it takes most people 16-17psi to make the same power.
You need to stop insulting us. It's our forum and if you don't like it, you're welcome to get the hell off of it. If you're willing to learn, and respect the people here who know more than you do, you'll learn a hell of a lot from this forum. I know I did.

Thanks Marc. Yeah I will try to find the limit of the 6-spd. We will findly know how strong they are. Then again i remember reading someone pushing 470 through theres. It was the e85 build. I think he was running 6-spd. So maybe the engine would go first.

Goddamn it, do I have to do everything around here... the answer is 28.64psi. At 28.65 EVERY B6 and BP will crack on the front side of cylinder #3 at 11:48a.m. while on your way to lunch. You will leave an 84ft oil slick, and drop 4 pieces of rod in the oncoming lane, in front of the red PT Cruiser doing 49mph in a 40 mph zone. DUH!!!
Seriously though, I dont think this is a very good question. Its like asking how old will I live to be. Some engines may handle more or less depending on many variables. No magic numbers Im affraid.

On a side note this is a VERY popular thread at the moment.
