I was thinking that, but since i already have it all apart, why put it back together again, and then take it apart again? Right now everything is very accessable, so im going to just wait and save $$$ and take advantage of it. Ill put it in once i got a single turbo and injectors on it and then go from there. I'm not in a hurry to get the motor in the car

Unless you want stronger internal (forge piston, piston rod, cam) then it a different approach.
Check this out it very useful http://www.moreboost.org/turbo_detail.htm
I like HKS GT3540.

How much boost do you want to run to make that 550whp? The GT35R is a good turbo, and would spool up decently quick on that 2.5L, but you'd have to probably run upper 20's for boost to make 550whp. The GT3767 (GT37 exhaust wheel/67mm compressor inducer) is also a good choice of turbo. It will start making better power per psi after 27-ish psi but at that point, it'll be making upper 500s to well into the 600s(so if you think that's what you want, go for it). Upto that, it still makes good power, but is a little laggier than a GT35/61mm based turbo (just because it has bigger exhaust and compressor wheels).

IMO, build it in stages starting with stock so you can get used to the power and the car itself and make it faster from there. Esp. since its your only car

why does everyone think i dont know about cars?
im not even going to describe my background history, aint worth my time.
so quit giving me **** and im asking for help from fellow lexus owners on what a good turbo would be. i bought my lexus to swap, i havnt even owned the car a month yet, is that why you all are *****ing? i thought ppl would like the idea of a nice hp swapped 1jz sc300, but it seems like more and more all im getting is a big glass of hatorade. I work one full time job, and im also starting up 2 business's, powdercoating and RI

the 1jz has a higher powerband than the 3.0 does and will make up the torque difference with rpms... JDM 1jz vs JDM 2jz, the 1jz has smaller turbos and same boost level yet still makes the same power

A normal R1 beat that EVO? If so, then that's kinda sad. That Evo should've been able to keep up and pull on a liter bike. I've raced an R1 bike and pulled at 600whp in my talon. My buddy's 690whp heavy *** MKIV pulled on a newer 03-ish R1. We both trapped 130+ mph in the 1/4. Not saying that it didn't happen, but maybe the Evo was down on power during that run because it shoulda walked an R1.
Back on topic:
Maybe the GT35R will make that power, maybe it won't at that boost. A local T66 powered 1JZ only made that much power (mid 500s) on 27 psi for boost....and that was with a bigger turbo. This is just my bench racing predictions of power as the EVO's head probably flows quite a bit better than the 1JZ head also.

with a few boltons it makes 185whp... its faster than a hayabusa by a nice margin with the mods; and its faster than one stock anyways..... he also has a nitrous bottle with a 30 shot on it (which he didnt use in the race or the dyno run)... new GSXR-1000s are nice too
I understand you're equating to older bikes... but 600s run 130mph trapspeeds now... the liter bikes approach or hit 140 (the R1 and GSXR-1000 anyway)
so far s the T66 goes... thats a horrible turbo to run on a 1jz unless you're running a head/cams and intake mani setup too... I dont think anything over a ~60mm wheel needs to be run on a stock 1jz
and no i doubt the EVO head flows better than the 1jz head... very seriously doubt it actually... maybe the head on the AMS EVO, but not stock...

Not turning this into a bike thread, but 120 mph cars can keep up with 600s pretty easily. It seems that cars with traps 10 mph lower than the bikes can keep up perfectly fine. I know what the new Liter bikes coming out are capable of, but a 135-140 mph car would at least keep up with the bikes. With my car trapping 132, it walked my friend's 03 R6 which "should" trap about 130 in the 1/4. This was about a buslength and growing from a 50 mph roll to about 140+. He's also a very experienced rider.
Another thing about the GT35R which in reality is just another 61mm turbo; on even the 3.0L 2jzgte, they don't make 550whp on 21 psi(and if they did a few times, it's not common). Another local has a 61 running 18 psi making a little over 460 on his 2jzgte, I don't see where another 100 whp could come from from a smaller motor with the same turbo. Only one way to prove it.... Do it, dyno it, Don't go off creep numbers, and let'r rip; just don't tune agressively just to make dyno numbers, blowing the motor isn't worth it..
Anyhow, yeah, get a turbo. Get it working, make some power with that little baby 2.5L. Good luck.
