T88 would be great but wouldn't you get more torque down low with a 5.7 over a 3.0? seems like supras suffer from that split second of boost lag whereas, say, an LS based motor will make torque instantly, just in time for turbo spool.
i dunno, i'm just assuming. i would still rather have a 5.7 liter with a turbo over a 3.0 liter turbo. but i like the supra body a lot more over anything. the curves on that car are timeless.
twin 88mm sized turbos on an LSx application?
You can manipulate your torque curve, by being a 6 speed. All you need do, is be in the right gear.
A small single turbo, say a t61 or t67, could make boost pretty much instantly comparted to a 42r or 45r

You can see here, a small capable turbo can outspool a larger motor'd car. BTW, how often do you see these supras losing with huge turbos. I can only recall two vids, of this happening and ones debateable. Even these domestics with stroked out singles cant do the job. Only when tubo Vipers come into the equation, are when things get interesting
if you have an 800 rwhp supra vs an 800 rwhp z06, who do you think would win? there's a lot of videos out there of fast supras racing cars that aren't as fast, so it's easy to see how it can win in those videos. what about even match ups?

If you build the Supra correctly you don't have to go from a roll at all. There are videos on the net of a guy I know here in KC taking 9 second liter bikes from a dig in his full weight plus stereo 900rwhp MKIV 6 speed.

Refer to above. There are also a LOT of 12 second 400+rwhp LS1s on this site as well.

FYI. a greddy T88 is a 72mm turbo and hardly Laggy. its NOT an 88mm turbo. and to get 800hp from a supra you dont need one, neither a $1800 intercooler. or $800 worth of gauges. talk about exaggerating prices.
are you trying to say a boosted 3.0 has more potential than a boosted 5.7?
Not sure who that was for, but I know Im not saying that at all. but the 3.0 holds its own. same was a 7.0 ls7 should have more potential than an ls1, but the ls1 holds its own. doesnt it? potential goes as far as your pocket is deep, not the size of your motor, how does your 5.7 (meaning you, no one else) compare to the average modded supra? face it, you can go really fast in a 1.8 liter 4 cyl, you can go fast in a 3.0 or a 7.0. you can argue physics all day but that the end of the day if you dont have the $$$ and the other person does, your probably going to lose.. here is a video of a viper that dynoed 1300hp running twin gt42 turbos against a 3.0 Nissan 300zx
When I look at that video do I think a turbo 3.0 has more potential than a TT 8.0? no I dont, it just clearly illustrates that winning is not all about power and Cubes.
What I really want to know is why do people feel its necessary to have one thing better than another? what does that do for you? people like different things, isnt that enough? Supras are not cheap, if someone can drop 30k cash on a used one. then thats what he wants, Im sure he knows u can spend a 3rd of that to buy and build a quick fox body. but that might not be in his taste.
M3's are every nice cars, not as quick as a 2001 SS with bolt ons, but alot more comfortable, and feels more solid. and more refned and is a totally different driving experience than what you get in a 24k pony car. sure he could have used the 60k to build an fbody, but not everyone gets off on hearing a camshaft lope and feeling the car rattle when idleing
Why cant people enjoy what they have without trying to compare to something else? how boring would it be or how special would you think your car is if every single person you ever ran into owned the same exact car.

Good point... However is see the OPs idea and will stand behind him on it.
A turbo 5.7, 6.0, 6.2, 7.0 or whatever (without considering that available parts will be an issue) ultimately has more power potential than a turbo 3.0. There's no replacement for displacement when you're going for monstrous amounts of power.
Considering that not a lot of people make 2000 hp beasts out of LSxs, the parts are certainly more readily available to make the 3.0 TT Supra faster than an LSx conversion. I don't think anyone is going to argue that fact.
My opinion... I think a Supra with an LSx is a great idea, and I'd love to do it myself, for two reasons, and two reasons only.
#1 I love the body style of the 93-97 Supra
#2 I love the LS series engines, and do not desire to own a vehicle with any other powerplant.
Maybe he just wants a mild 350rwhp street car... more power to him, if that's the case. Maybe he does want a turbo beast, and done correctly, I believe we'd all be drooling over the results.

THere is replacement for displacement and that is 4 valves per cylinder. The higher in displacement you go, the harder it is to make power. I know it sounds crazy but it is. Why is it that a 8.2 liter viper, makes the same as a 7.0 liter Ls7? Or why does a 3.6 liter Porshe, make more than an ls2? Why does a 5.0 liter M5, make the same power as a Ls7? A 7.0 liter 4valve motor, would make more hp, throughout the rpm, than a typical pushrod motor. Ask yourself why, was dodge going to replace the current model viper with a 4 valve? Or why did they opt for VVT? If Chevy plans on making more power with the ls7, there going to have to:
A) FI
B) 4 valves per cylinder
Ask yourself, why do 350z's make 420rwhp on 8psi(3.5 liter), while a camaro V6(3.8 liter) makes 420 on 15psi? Or why do Honda D16( single cam) motors make 200rwhp on 7psi, while B16(twin cam) motors make 275-300rwhp on 7-8psi? Head design, flow, VE, all play a part in determining hp, not just liters!
And then that "over rated" GTE will still kick your ass.
SO WTF if he does??!!?
I still "dissed" his "perfect" TOY by dropping a "low tech" <--- domestic V-8 into the engine bay. Besides, do you worship these things (GTEs) soooo much to really believe that with enough time/effort/cash/tuned boost into an LSx/domestic V-8/10, your TOY motor still cannot be beat??!!
WOW, I guess they really are invincible then, huh??
Nippon uber alles, right??

Again, how many ls1 motors have run mid 6's on stock base motors? Not iron ls1's(becuase there were no production iron ls1's). How many vipers have run 6's. I find it funny that everyone talks about ci and liters, but import owners use there factory based blocks to run these times. Fastest 350z has run mid 6's with less than 4.2 liters at 218mph. Supras have run mid 6's with 3.4 liters. Rx7's have run 6's. DSM's have run low 7's. A cobalt has run 7's. But yet it takes a stroked 422ci blown+ nitrous ls1 to even come close to those times.

Well if you want to perform a swap like that, be my guest. An ls1 supra, would never own a 2jz supra in any category. Dollar for dollar, a supra would inihilate(sp) an ls1. Supras run 8's on stock 6speeds and longlblocks. I would love for someone to show me 5 vids, of an ls1 beating a modded supra? Hell show me 5 any domestic. For all the shit talking you do about supras, they own streetfire, goggle, youttube, etc...... You rarely see one losing. Another funny thing is, a stroked out viper with a twin turbos, gets yanked by a 3.0 liter:
This is EXACTLY why I would want to do this!! It would make all of the GTE worshippers moan and groan in abject AGONY!!
