I was told they were 4.11's, but they don't feel like them at all. My 1st gear does end at 30mph. I can't wait to run him before I leave for school. I should be able to get, considering the driver mod. Watched him drive, he keeps stalling out. He won't give himself the time to learn about his car, which really disappoints me. Btw, the MKIII supra's do look pretty good, but nothing looks better than an IROC!!!!!!!!! LOL!!!
Originally posted by som6969 Ok it is a borg warner 9bolt but it has 3.23 gears in it(counted the teeth when I changed the gasket and fluid in the rearend) . And The tach is not what I am going by I have a megasquirt engine mangement system I just plug it up to my laptop and I can control the whole engine from inside the car on the laptop. And the rpm is running between 2800 and 2900 at 70 mph in 3rd gear. I got stock size tires on the rear also. So on my end it doent work.
were you coasting or did you have your foot slightly on the gas holding it steady at 70?

Keeps stalling out? How long has he been driving a stick for? If he can't even move his car without killing it I'm gonna go ahead and say victory for you is pretty much assured since when he goes to powershift third he's gonna shift into first and blow his ****
He just learing. Said his next car had to be a stick. It's basically his 1st time really. He's definitely no expert and won't become one over night. All i gotta do is punch and go. Supposively his and his boy's car are gonna be supped up when i get back from WyoTech. I'm either gonna boost the 305 or do an LT1/T56 swap (leaning toward LT1 swap, for the fact the these guys think boost is almighty) and take them out. Long term plans though.
Oh, btw, my sorry *** is gonna have to learn how to drive stick once I swap in a T-56 (which i will try to do while in school, if i can find one for decent price, LT1 will come later). I don't know how to drive stick either, but want to learn how to, for the future.
My '97 has 53k miles and it still has the stock clutch. T-56s don't eat them any worse than any other stick behind a V8.
If you're just learning, then learning on a motor with some power is INFINETLY easier than learning on a little 4 banger or a 6 cylinder.
And if you're really serious about the LT1 swap, theres a ton of information in the engine swap forum. However much I love the LT1 (i've owned two) coming from a thirdgen IMHO you'd be better off swapping in a 350 Gen 1 SBC, rather than going Gen 2. But if you really want to, get ready to put down ~270 rwhp from a bonestock motor (full bolt ons will get you about 330 rwhp) and run mid 13s on your street tires.
An L98 would be an easier swap and mated with a T-56 and good driver would be ownage. Plus it would be lot easier to swap and pretty easier to net power out of it, as with any other small block. I'll do my research before i hope into to something.
All in all though, i will go with the LT1 swap. Hopefully find a donor car and call it a day. I just would love the fact of having an LT1 mated with a T-56 in my IROC. 10 out of 10 cool factor. And later on in life, if i feel the need to boost it, procharger here i come!!!!!

Just make sure to upgrade the Optispark ignition to the 95+ distributer. Optispark is the one flaw to LT1s.
330hp at the wheels in a 3rd gen should be low 13's and possible high 12's. Heavier 4th gens ran run 12.9's with that same power level.
GM high-tech says otherwise Shifty they got a 3rdgen to run 12.36 1/4 mile with 333rwhp, 416hp crank, 26x11.5 ET streets radials, 355ci, flat tappet cam, HSR fully tuned, TH350 w/stall, 3.23 gears, and the only weight reduction was the skinnies up front.
You can run about 14psi with the stock turbo. You can do 500RWHP with stock internals easy.
My Mk3 Supra went 14.9 at 92MPH stock. But the 89 and newer Supras got slower and slower due to weight increases. Plus my MK3 is not a targa,has no ABS,no auto and has cloth. I say work on traction and run him from a stop. If he is inexperienced he will lose. Plus the fact turbo was an afterthought-the car may be in poor shape.
Where gonna go at it. Should finish installing entire front and rear suspension compenents tomorrow. Btw, I also gotta Sn-93 paxton coming in a few weeks. With the LT1 cam and some fine tuning, i should be golden with the 305 for awhile.

Its not all about the power. 330 rwhp in a third gen with the right gearing, and decent traction should get you into the low 12's.

Your statement about 500RWHP on stock internals is misinformation.
There's absolutely no way. I have yet to see an 7MGTE car that is even all that fast without aftermarket internals. Which I'd call sub-12s fast on a Turbo Supra.

You are talking about the MKIII Supras and not the MKIIII right? As far as the MKIIII's go, I've yet to see a Supra that isn't fast. The MKIIII's can actually easily acheive 800whp with NO internal modes.

Yes, the 7MGTE is a MKIII motor, not an MKIV. 3.0 L, DOHC, single turbo, 232 hp/255 lb-ft stock. Same displacement as the MKIV, but not quite the same beast.
Right MKIV, not MKIIII lol. Anyway, I know they've got potential, but you are right I think. They tend to have weak head gaskets, and have a few too many vacuum hoses, but beyond that I think they've still got a ton of potential as far as I know.

Yeah, with some good forged internals they have really as much potential as the MKIV motors. You are correct about the headgasket issue, it's the weak link to the 7MGTE by most accounts, in terms of increasing boost. And while I don't know the specific point where they tend to blow out, I know it sure as hell won't support 500 RWHP. I also know that the factory internals won't handle that either, which is why these cars are somewhat expensive to build.
Update. The car is up and have been driving it for a few days now. Feels a helluva lot better than before. With all new steering components and suspension parts, it's like brand new. Lights em' up like no tomorrow. It's getting an alignment as i type. Told him about the paxton, he must of told his friend about it, and now he wants to get a either 1jz or 2jz. Jesus. Will post results soon.
if its anything like the turbo 89s around here you should beat it . theres one that runs at the fair grounds running 15.0s stock.but that in tennesse are times are always a little lower.
Well, his ain't in tip top shape, needs alittle tuning, but who doesn't these days. Hopefully I'll get it done tonight. Well do a couple of digs and roll runs, see how i fair. Later.

Look on my webpage. 11.78 at 123MPH on a stock bottom end motor on pump gas.. Nothing changed at ALL. OEM Toyota with a new oil pump for saftey(Toyota pump too). 512RWHP tested at MSP in Frederick MD. I just hit 502 RWHP with a smaller turbo. There are three on Supraforums that have done almost 600RWHP with stock internals. Weaklinks are the ringlands and pistons. You ping-you die. If you rev the car high(ie cams) you should do rods. I have built 35 of them in the last 15 years.
Stock headgasket is not the problem. The problem is that the headgasket was not torqued down by Toyota to correct specs. Over time no matter whether n/a or boosted the headgasket will go. If driven for years the head can warp etc.... You can run any power level you want with a Toyota headgasket.
Just because you have not seen them-doesn't mean they exist. The 7MGTE motor is not stout compared to say a 1Jz or 2JZ but they can put out some power.
"Yeah, with some good forged internals they have really as much potential as the MKIV motors"
Not true by a long shot. The cylinder head on the 7MGTE is limited compared to the 2J even with bigger valves. Not only that the 7M is a long rod motor. You could destroke it to rev it.
BTW one guy hit 700RWHP with N20. I will have to find his page and video.
Here are some other guys:
Been trying to tell my boy that he can work with the motor he has. Should just give it a chance. He new to the car world too. Hasn't really gotten his hands dirty. Anyways, wasn't able to get alignment done today, due to that autozone gave me the wrong tie rods for my car, which i some how got on there anyways. Went to a local speed shop and picked up the correct ones. It should go down tomorrow, right after we both leave the exhuast shop. Both have leaks that need to get fixed. Will keep yall posted. Mike 92Lx, can you suggest some small beginners mods i can tell my friend? He keeps looking for a motor to swap (without the money or knowlegde to do so to being with), but his motor has all he really needs for now.

I've been to the Supraforums before, and I was quite sure 800 rwhp was possible on a blueprinted and built 7M motor. While it's not like 1200 hp like top-build 2j motor, it's going to keep up with most modded 2j cars.
You know what 400, 500, and 1000 hp supras have in common? Mid 12 second timeslips. Ha. Ok, before anyone says anything I don't need a lesson. I let track trends do that for me. Couldn't resist. Sorry.
80s fan 800RWHP is possible but nitrous would have to be used.
link first of all fix all mechanical problems and make sure the car is ready to be modded. A leak down test is imperative. If the headgasket has never been changed-better check up on it.
Capone sad but your words are mostly true. Supras are not ideal cars to race at the drag. Heavy,tall first gears,no low end power and big huffers on most mean crappy ETS.
OK. Just got back from getting the alignment. He's in a meeting right now at school. Hopefully we get are exhaust leaks fixed up a what not. I still gotta change my oil and put new o2 sensor in. Will get back asap.
