Wow, first I heard of a 5spd being more fragile than a 6spd...

Only real-world experience I have with this is friends with Evo IX MRs using the 6spd and Mitsubishi's decision to shit-can the 6spd and ONLY provide the 5spd manual because of beefier gears for the generally same housing size.

I did not leave suspension off my list, it is step 3, the handling ;)

The reasoning behind 13" brakes is because it would laugh at the job it had to do with stopping a 2,000 lb car. If you go overkill, that means (IMO) more heat dissipation and no worries from the braking department.

EWG is definitely what I'm leaning towards, it'll just be a bit tricky in the header design and I've looked at ways of getting more space in that area (in the DIY section)... ton of shit to consider unfortunately (heat shielding, down pipe angles, minimize sharp bends on the intake/hot-pipe ducting, clearing enough space for the modified radiator shroud).

Again, I do appreciate all of the input and I'll be sure to cover all grounds before this thing is done. I plan on having every aspect mapped out using this forum's collective trials and errors from the past 5 years or so to help me make my decisions. Then I'll buy the car and a good 75-80% of the parts all at once :drool:

Just a little update, I'm converting the Evo X to E85 soon, hoping for 360awhp, 420awtq on a Mustang dyno.

I'm house hunting and hopefully getting a large garage and starting my Miata project.

I was 90% sure I wanted a turbo 1.8L 94-97 NA when I joined here and made my first post.

I am now about 60% sure I want to go naturally aspirated V8 in a 92 or 93 NA :loser:

I'm swaying more and more towards that as I continually think about it. The sad part is I don't even have a Miata yet and I'm more excited thinking about that build than I am with my torque monster E85 conversion on the Evo :jerkit:

So, with that being said, I'll likely be lurking in the v8miata forums instead of here... what's the relationship between that other site and here? Same type of family or is it "those guys" type of mentality?

Thanks for all the info I've already read on these forums.

v8 for sure. Turbo is lame lol

A few of us are on both. No those vs us guys at all that I've noticed.

Same host, no? At least, I got stickers for both forums together in the same envelope. :D

Pm Urbansoot, he has a 70-80% complete Ls1 swap into a NA that he has been bipolar on. Right now he says he is going ahead with the project, either wait 5 min for the next part out, or make him an offer. You may get it.

Those numbers should be no problem with the X turbo...a friend of mine made your goal numbers on an EvoIV turbo on e85. I went 328/361 on a DynoDynamics with a stock EvoIII 16g + e85 in my Talon and you've got a lot more turbo there. If you can nail down the boost drop you'll do even better. I was spiking to 32psi/holding 27psi on the 16g with 21* timing and it was a blast.

I definitely feel you on not wanting to throw more money into anything but a Miata, too. I'm dieing to get my hands on one and get that 16g bolted up. Good luck with the v8 swap if that's the direction you decide to go...will be a fun car either way!

Same owner, different crowd. Most of the V8Miata crowd go their and to the engine conversions forum on m.net.

As others have said, if your looking for a track rat- put a 6 point bar in, seats, and harness. Now its time for 6UL's and NT01's. Then do a front sway bar with brace and blocks. Follow it up with FCM coilovers, Poly suspension bushings with grease fittings, and adjustable end links. When your bored with that on the track, an L33 engine with V8R's swap kit will give you unlimited grins from ear to ear. If you end up getting bored with even that, then the sky is the limit. 500rwhp Lsx's are a dime a dozen, and all you then have to do is drop it in. With just the L33 5.3, you will make enough power to drag a Ferrari 512TR like a dog on a leash. Proven...... twice :)

Don't leave here. Not because I'm in love with your X, but because the V8 forum doesn't have the #'s we do. That's a better place for V8 knowledge of course, but we have a great knowledge base here for the rest of the car. Race prep for the interiors, aero, wheels and tires, that kind of stuff is mostly stock a m.net, and often off the hook here. Not sure what a lot of the V8 guys do, but you might only get one or two examples.

As Curly said, this place has more open information about general race prep (ducting, braking, and aero mods). The hardcore racers (perryrace, Modracer33, and a few others) on V8m.net and the engine conversions section of m.net know their shit, but are not super open about the real tricks of the trade to very many people. Most are like me and just building a toy. Far fewer arguments on the other sites, as the groups as a whole is much older.

In order to get a vast wealth of knowledge if you doing a V8 swap is to visit all three places. If your sticking with a turbo 4 setup, this place is your one stop shop to everything turbo heaven. A lot of VERY knowledgeable cats in here.

Good stuff. Thanks again everybody. I will update here with what the Evo puts down and of course when I get a Miata.

Ideally a rear mount LS2 in a '93, but we'll see how it all ends up next year. Oh and good point with the handling / track prep info, will definitely come here for suspension advice.

Ah shit I totally forgot...

Aaaand... I entered a little video contest for Auto-X and got 2nd place. First loser gets no prize... which would've been a free rear sway :crx:
