Power, RPM, AFR's, Timing, cooling capacity, and probably some other things all tear up an engine if it's not right.

You guys are a bunch of wooses. I run my stock motor with 200K miles on it with the wastegate welded shut. I get tons of power when the boost climbs to 50 psi. It's awesome when I drag race at the local Air Force base against F-16 fighters on full afterburner takeoff, and leave them in the dust. I got some 2.08:1 rear end gears to keep up with them.

Listen man, if horses were wishes, we'd all be eating steak.

Understood. I got the book Maximum Boost to help educate me on this topic. I haven't gotten around to reading it yet because I have been busy studying tuning theory. It is next on my list though. This will be my first turbo project. Sorry for the plane fact that I am a Noob but I am approaching this whole project as a learning experience.

I realize that torque is going to be the determining factor on how hard I will be able push it before the rear end breaks. I have the torsion Diff in the back. Any ideas on the limits of my current Diff?

The BS isn't necessary. I'm not stupid just merely new to the subject. I appreciate what guidance you can give me.

I suppose it's too late now but I'd suggest you've done this in reverse. Max Boost will educate you with the key fundamentals, thereby reducing your need to post the questions which have resulted in the annoying flak you've received. Understand the basics then tuning theory can be usefully implemented.

Not sure what planes have to do with any of this but I assure you this will indeed be a big learning experience, most of which should be fun (assuming you like cars and ****).

Your driving will be the determining factor. Available torque just increases your need to exhibit mechanical empathy. The Torsen is the strongest of the OE Miata 3rd members.

I started with tuning theory and an Engine Management System so that I can learn the system/interface before boost complicates things. Plus I decided to keep the car naturally aspirated while I began my love affair with her. Since the summer is coming to a close the time has come to up the ante and make things a little more risky.

I don't even know why I am wasting my time dignifying this with an answer.

Actually I think it is. The information you seek is probably already here. Just search for it. mt.n helps those who help themselves.

That's nothing.Ihave a 15 gallon air tank I fill with my compressor hooked to my intake.

I boost 120psi on a regular basis.I have a reverse mounted hoodscoop and a Super Soaker for water injection!

I have a fresh motor just rebuilt with used parts.

I just have your Mom fart into my gas tank. Highest octane fuel I've ever used. Cheap and easy too.

Actually, the differential itself is not the weak point, so Torsen vs. Open makes no difference. What tends to break is the ring & pinion gearset. This is a fairly common problem on the '90-'93 cars, which use a smaller ring gear, and the solution is usually to upgrade to the larger 1.8 style diff that you already have, which tends to be fairly robust. Lay off the smokey burnouts and clutch-drops and your diff will be fine.

Transmissions, unfortunately, tend to get used up after a while. Fortunately they're cheap and not terribly difficult to swap.

Heh. Relax, this is just how newbs get welcomed to the forum. It's a hazing ritual.

Big Boy

I'll beat you all in my old school 538HP "muscle" car.

Big Boy

What tends to break on them? Is it the gears? I have heard of people swapping RX-7 gears into the transmission. I guess it takes some grinding on the case in order to get them to fit but it has been done. I haven't found a "detailed" writeup on this yet so forgive my lack of detail.

Joe thanks for the info.
