I have an 84 supra and i want to put a 1JZGTE in it. What exactly am i gonna have to modify to swap this engine with the original? And am i gonna need to get a different transmission?
It is going to take a lot more than a new trans. You will need custom motor mounts, trans mount, new trans, new drive shaft, radiator, intercooler, a lot of wiring, etc. The 1JZ uses the later model round style motor mounts that were used on the 7M. I do not know if the MK II 7M swaps use the round style mounts or the older square mounts, so there may be an issue there. In short it is not a "bolt in" swap. It will fit in the engine bay, so if you are serious then go for it. There are also a few 1UZ swaps out there.

I'm not sure the 1JZ should even be conceived for the MkII. It's an enormous amount of work, for (IMO) little gain over the 7M.
I couldn't disagree with you more. It's no more work to put a 1J into a MK2 than it is to put a 7M....and 1J are MUCH more reliable than 7M's.
You can mate the MK2 tranny to the 1J with a R154 bellhousing, but it won't last very long. Your best bet is to buy a front clip which will come with the tranny and pretty much most of what you will need. You'll need to make motor mounts, use the MK2 auto tranny mount (for the R154 5 speed) shorten the driveshaft (or do what I did and get a custom 1 piece driveshaft), use the MK3 radiator (with minimal modification to the mounting points). The most PITA part of it is the wiring, which isn't that bad, and really no different than the 7M, I just hate doing wiring, which is why it was such a PITA IMO. My MK2 has a 1J, I'm on the stock twins, I have BPU+ upgrades, and I'm running mid 12's on street tires and mid 11's on spray....on STREET TIRES!!!!!
You're a moron. Displacement > Boost. So then you add boost to diplacement and.... ?
And that's why we see all these V8 supras around .....I believe you are the moron. If V8's were so popular, then why do most MK3 Supras swap to 1J's or 2J's instead of 1UZ's? I come from a backround ov V8's and sure, due to displacement they make great wide torque bands, but turbo 6's are what everyone's doing. I've had many many V8's, making a full range of power from 400rwhp to 900rwhp.....and tell you what, the fun factor in my 1J is much greater. 1J and 7M turbo parts are a plenty, V8 turbo parts.....um, yeah, you'd have to make them yourself. Dollar for dollar in the import game, the turbo six wins.
1UZ is newer than the 1JZ and 2JZ by far, however it has proven better in many ways. Right now the 1UZ territory is dominated by people who are leadingthe way and pioneering things. Reg Reimer was a pioneer in the 7M and MkIII game, and look where that lead. Also, the 2JZ and 1JZ are trendy and trendy doesn't mean crap, it means just that, it's trendy. Big aluminum wings on sub-100hp cars were trendy, does that mean it was 'good'? No.
Playing the dollar for dollar game (especially with you) is a losing battle; You have a 1JZ. So, tell me how many junkyards in the USA have 1JZ (Not 7M or 2JZ) parts in them?
As for our preferance in 'fun factor', we have Supra biases otherwise we wouldn't be so hard up for them so I don't think arguing a bias as to which 'felt' better is accurate due to our preferances.
I've raced S281/S351's, what's your point? You and I both know you can't arbitrarily point out two random cars and compare them by just what block was originally in them. I admin a site with 4000+ members including turbo 302 foxbody mustangs that run 8's in the quarter mile and strive for 7's. So in that respect, I can play the same game, why not put in a Ford 302 and boost the unholy crap out of it? It's cheaper than the 1UZ, 2JZ, 1JZ or 7M. However, it is commonly held in the Supra community that A Supra is defined by the inline six, a Supra without one is not worthy of the Supra name.
So, conclusion:
Cheaper? All supra's are Expensive. 2JZ (Because it's Trendy), 1JZ (Rarity/Trendy), 7M (Old), 1UZ (New).
Dollar for Dollar? Common domestic's are FAR cheaper due to how common they are. See previous.
Powerful? There's no replacement for displacement. Period. Boost AIDES, but does not replace. All Motor 500hp > Turbo'd 500hp.
Fun? User Preferance. Always.

I can't argue with that. As a matter of fact my buddy's shop has a stroked 302...a 347 boosting 45psi, and yeah, it makes stupid power, over 2000rwhp, anmd runs 7's in the 1/4, but it;s not a street car. Seriously, to be honest, I've always wanted to build a nice highly boosted v8, and we have a big block chevy at my shop that we're not doing anything with, so it's on the table for work right now. And the only reason I got as defensive as I did is because you called me a moron. You don't know me, know my backround, or know what I am capable of, and to sit there and call people morons because of a difference of opinion is just plain stupid. I've raced and built race cars since 1989, in all shaped and forms, from turbos to nitrous to naturally aspirated, and from V4's, inline 4's, V6's, inline 6's, V8's, inline 8's, and even a V10 we also have a 4.6 liter inline 8 from a '52 Buick at my shop that we're playing with. When it comes down to it, it'sa not a displacement race, it's a combination of right parts race. You can have a 500ci big block lose to a 2.5 liter inline 6, if you have the right combination ....and I have. So next time why don't you put up your reason for saying what you're saying rather than calling people morons
Well I guaruntee you that that cobra isnt running 16 psi either. Lets compare apples to apples here.
You can't compare a Supercharged V8 and a Boosted 2.5L I6 in the apples to apples discussion. Two totally different platforms nevermind the differences in forced induction performance and method.

Well, lets see, the Cobra makes close to if not more than 400rwhp, and I make 320rwhp, he has DR's, I'm on street tires, He makes gobs of torque, 1JZ's are called torqueless wonders....Yeah, I guess you're right, this isn't apples to apples. He should whoop me. My motor is stock, I have a downpipe, exhaust, an intercooler, and an intake, so a couple bolt ons. So as far as motors go, we were both stock.
I don't even understand why you're saying compare apples to apples when Jeeves said a V8 is better than an I6???

So then what are you comparing? You said a V8 is better than an I6, or that displacement wins over FI. You were comparing apples to oranges yourself. My 2 tiny CT12 turbos add up to the size of a T25. I'm sure the Cobra supercharger has way more output than a T25 or 2 CT12's

I know plenty of 1J guys here locally making over 800rwhp, and a few making over 1000rwhp, and one making just over 1200rwhp.....all from a 2.5 liter motor. Any motor with the right technology, the right combination of parts, and/or the right amount of money can make a lot of hp. Putting that hp to use is a different story. Hell, the Mopar SRT-4 that races at the import shows makes over a 1000whp from a 4 cylinder. The Grand National was a 3.8 liter V6, and they made gobs of power, so you see, this isn't the 60's, 70's, or even the 80's anymore. The "There's no replacement for displacement" phrase has been replaced years ago with "There's no replacement for technology" or "There's no replacement for cubic dollars".
