That boostlogic kits looks good.
Rather buy a complete kit its alot easyer.

ya, i found these http://www.boostlogic.com/catalog/p1...duct_info.html but they are VERY pricey.

if I didn't do 315's and ran like 9.5's, how much traction am I gonna lose?

and I saved the link and such to that turbo kit, as for the exhaust I would like a nice sound as well, that's why I was looking into exhausts, but I also don't wanna be the guy driving by scaring people at idle and getting tickets, I don't mind when it gets into the RPM's its kinda getting loud but that's sorta what I'm looking at ..

and with that turbo kit, will the OEM auto transmission handle that fine?

well i have 9.5 on mine with 255 tyres on and have no traction 1/2 or 3d gear and i have just over the 550 whp.

Staying with oem TT 9.5" wide rear rims (275-width at most) will really limit your potential Anything over about 350rwhp or so will probably just sit there and spin. It's also quite dangerous, since a 'rear happy' car can be tough to keep on the road.

I doubt your oem n/a auto transmission will handle that kit for very long (or any na->T turbo upgrade, for that matter). I'd say drive it till it breaks, and save up for an oem TT auto (or a getrag v160 6spd). If you don't drive it really hard, that oem n/a auto may last long enough for your savings to accumulate.

how much will each of those tranny upgrades cost?

Sorry to say I'm not really sure. I do know a brand-new V160 from Toyota costs about $6K USD all on its own. Of course, you'd buy it used...but even that will likely be about $2500 if it has no issues.

well, a 6 speed swap, which i would love, is really gonna cost me, because diff and clutch and all that i need new, as well as a driveline probably.

but there is this http://www.suprastore.com/titmss2tosub.html so i'm definitely got some choices.

One other consideration - daily-drive your n/a Mkiv unmodified, and save up the $$$ to trade for a TT. By the time you upgrade the turbo, and the brakes, and the transmission, and the differential, and the electronics, and the rims, and the suspension, etc., etc., etc., you'll more than pay for the difference beween the two vehicles. Do the math and you'll see for yourself...

Considering going back to driving my honda lol and just trying to sell this one for a little more then I got it for, i got a good deal from a long time friend. & he needed some cash now for his new daughter and that was just a weekend cruiser. so i'm considering just saving to buy a low mile TT in the future that has everything I want, (targa, and auto)

Glad you wrote that buying the exact Supra you really want (i.e. a TT) is still an option. However, I hope you don't mind if I remind you that if you're going to autocross, you'll be faster with a 6spd. 100% for sure. Roadracing too. The only thing an auto is usually faster for is drag racing.
