1JZ monsters
Hey everyone
I was just want to know if anyone is running a T67 or T78 or T88 on there 1JZ. Im looking for big power figures so what are some of the highest outputting sc300 on this forum? Also with supporting mods to my 1JZ with a T67 such as injectors, aftermarket ecu etc what power figure would i be able to achieve? What’s the efficiency range for the T67? Also I can’t seem to find any specs on T67 turbos so if anyone can tell me their power rating and any relevant site for specs that would be sweet. Ahhh lastly if you got any links to any sc300 or 1JZ’s in general pushing 500+ hp that would be awesome.
Cheers

Gee, your not asking for much huh
You will not find many (if any at all) on these forums that are running big T's on a 1JZ, most will be 2JZ as the 1JZ is harder to source aftermarket parts for in the States. I belive there are a few that will be doing it on these forums soon but no one that I know of just yet.
As for what power figure you would or could achieve. Well there are too many variables to take into account and no one can give you a proper figure. It would depend on the supporting mods really.
There should be loads of info out there about the T67, you are not looking in the right places maybe.
You should visit the ALSC as the aussie guys down your way are much more familiar with the 1JZ and a few on those forums are running some decent power.

See, when you say t78 or t88, do you mean the greddy mistu turbos? A t78 is only roughly 68mm and I believe a t88 H is in the low 70s in MM. Greddy just makes their turbos sound big.

This will fully explain everything: it actually for 2JZ but worth the time to read I think it can be apply for 1JZ too.

They are all very laggy and inefficient compared to the turbos out today...
If anyone on this forum begins to do a big single install on their 1jz, it wont be with one of those piles of crap It will more than likely be with one of the newer GT-based turbos or SP/PTE turbos setup for the JZ engine (various 67, 71, and 74mm turbos)...
they spool faster, have way more options, and are far more efficient...

For my Boost/cooling/exhaust:
1. Greddy T78 turbo kit, going to be tuned at 18psi (~1.2 bar)
2. Front mount intercooler
3. 3" piping from the down pipe all the way to a 3" dual exhaust
4. GReddy 1.4mm metal headgasket
My Fuel:
1. Walbro 255lph fuel pump (Might need dual walbros)
2. Sard 800cc High impedence injectors
3. Sard fuel pressure regulator
My Engine management:
1. GReddy E-Manage Ultimate <== need to install this weekend
Whether or not these mods give the 500+ HP, I am not 100% certain. I would like to believe that they do. If you wait like a week or two, I can give you a definite answer. However, like what Griffin TT said, you should check out the supraforums, 1JZ swap section. That is where I got a lot of info. Best of luck to you and if you have other questions, feel free to ask.

Yeah with that much boost running through the T78 you should be hitting around 565rwhp roughly. Im currently almost at 500rwhp running only 1 bar. This is my dilemma, i wanna run the turbo at a safe level that it was designed for, but i can’t find much info on where boost will be still safe for the turbo. I've been told at between 22-27 (1.5- 1.8) is still safe and is the most efficient for the turbo, coz need clarification on this. Running that much boost should see me run around 600rwhp+
Should be good to see your results when done. Also are you gonna run any NOS? I've been playing around with the idea for a while now and have decided that ill be going down this path. It will only be using probably either a 75hp kit or 100hp kit to help the turbo spool up and eliminate most of the lag. I've researched it a fair bit and it should do wonders. Also my friend who runs his S15 Silvia in the low 11's gave me the low down on the benefits as he has spent countless hours fine tuning his drag S15 and he praises NOS for eliminating most of the lag he suffers from his T51R.
Are any guys running Nitrous in the States? I know there is 2 SC300 running it in Australia. Any opinions?
