today i bought a
"greddy TD07s-25g 1jz kit"
what kinda power could i expect from this on an otherwise stock motor?
anyone seen these in action either on a 1jz or any other engine?
any ideas of when boost would be useble?
would cams help?
what ecu and injectors to use???
its all going into gz20 soarer with 1jz non vvti
lemme know

my power aim is 450 hp at the treads
and maybe a big power run once to get a big show off hp figure

The TD07 is a HUGE turbo for a 1JZ. I wouldn't expect it to spool up until mid-high 5000rpm. You'll easily need a new ECU, injectors, intercooler and other work (maybe cams) to get it to run properly. Lag will be pretty bad on a 2.5 litre engine though.

Think how many pairs of undies you're gonna go through once it comes on boost! Jesus man, is this a daily driver?

car already has a large hks cooler
os giken triple plate and cusco diff
so in theory all id need to get her going is big injectos, and ecu/tune and fuel system to support?
would cams/ cam gears help at all? or the benifiets out weighed by the cost?

from what I have read 264 degress is the biggest cams you can go without making it idle rough. I would be looking into some cams as well as an ECU that can raise the rev limit a bit as you don't want to hit boost and then have to change gears straight away.
Everyone knows the bottom ends are strong but does anyone know what sort of revs the valve springs, valves etc. can sustain?
You are a lucky fella Rossco!

264? Bah, pussy! 
I know for a fact that 272 cams will idle fine on a 2JZ (a noticeable lump, but nothing horrible), so I think it's fair to assume they'll be OK on a 1JZ as well.

I suspect tuning plays a major role here. A friend of mine has 272 cams but he also has a Haltech; if you tried it with a stock ECU it would probably run like crap.

Very good point dude. With a turbo like that you would be hitting boost so late that you would run out of revs real quick...
I also agree with MR 1GGTE'a last comment

i dont know about the actual physics of the TD-07 25G, but i know that twin TD-06's work well on a 1JZ. about 500 odd RWHP worth of good, and there was still more left in the turbos. full boost should not be coming on REALLY late, just late 
as for power, 2 TD-07's can support about 800KW on a 2JZ if thats any idication  
the bottom end seems to be the limiting factor in the rev department for a 1JZ. not strength, thats no problem, they just dont seem to want to rev. about 7.5 - 8k is what i hear.
cams, ecu, and seriously trick manifold are gunna be needed for that kinda revs though.

The 1JZ is stupidly revvy thanks to its very short stroke... getting beyond 8k will be a walk in the park with a suitable valvetrain. Hell, even my 2JZ with its much longer stroke has the rev limiter set at 7.2k!

I've heard of a need for brass valve stem seals or something along them lines when revving soo fast otherwise the seals implode on themselves.
this came from someone running a 1g to 9500rpm

hmmm
obviously its going to be a laggy mofo
and i dont really wanna open the motor up, what would be a suitable redline to use?
ive read a few guys have 8200ish on totally stock motors with aftermarket ecus with no dramas
any ideaS?

well, that is basically what i was getting at....
without some major internal hardware that is suited to revving hard, there has been some issues.....
with the right cams, there should be no problem with an 8000 rpm redline... this is what all the literature i have read seems to agree upon... tuning and cooling is DEFINATELY the key though.
anyone feel free to correct me if i am wrong ( as this could easily be the case... )

not to sound like i know everything, as i shall be the first to admit that i dont, but factory redlines dont mean shit...
i dont know whether it they rev nice and smooth with no damage to 8000 stock, but most tacho redlines are over rated....
and besides, its one thing to have the revs, but they dont need 8000 while stock... the max power is at 6200, so why rev a stock one past like 6500.... seems kinda pointless to me...
but like i said, im happy to be corrected at any stage, as i am by no means an expert.
p.s, if this comes across as arrogant, believe me, that is the last thing that it is spose to....

My 1jz has a factory redline at 7000rpm. There was some discussion that the manual versions were a bit higher though.

As I said earlier in my post, I've hit 7.2k in my 2JZ (stock engine management), so it's a bit silly to suggest a 1JZ can't go past 7k!

bare engine no turbos no intake manifold. they are plentiful.
just pick up a phone and ring around.
i did hear of one person buying 3 at one time and getting them for $400 per unit cause of the bulk buy.

i see this thread is a little old but i'm reviving it from the dead as it's relevant to me at the moment.
I have a 1J in my soarer also with a TD07 on it. I'm running a microtech LTX12, have big intercooler, HKS external wastgate. The motor has been built up as it has a cam, cam gears, forged pistons, h beam conrods etc so should be pretty tough. Anyway after my first tune i got 245.9 rkw @13psi which aint bad for low boost bearing in mind also that the TD07's are meant to really come to life from 20psi.
The TD07 comes on song way to late for me and i'm pretty keen to downsize my turbo as it's hell laggy. Once you surpass 4000-4500rpm she begins to pull but it's practically time to change gear when your really feeling the G's. Anyone got any suggestions on a good turbo for a 1J that will boost up quicker whilst still being able to get good power output even if it be at runninng higher boost than u might to get the same out of the TD07? Also anyone intersted in a TD07?

Garret Gt30R seems quite popular for a daily driver application and depending on your choice of turbine housing size can spool earlier or later with power guideline around 400rwhp with a good tune.Obviously a slightly smaller turbo will make a little less power but deliver that power earlier.
How much power is enough? personally I would like power on tap by 3500 revs but I am very conservative with my revs.I think those monster tachos with shift lights are a bit over the top but when things get frantic it cant be bad having a big light in your face screaming "change the gear stoopid" as its not uncommon to hear of guys spinning a bearing.I assume this is caused by over revving?

yeah, i was thinking something along the lines of a GT35R which is pretty close to the GT30R, correct? Would would be the difference between say a GT35R and a GT35/40R, reason i ask is i know someone selling the second of the two for a good price. In regards to the specs commmonly quoted on turbo's what do each represent and mean in terms of the way they perform and function?

I am a newbie to studying turbo specs,It gets quite complex if you like details you can compare-
wheel sizes,wheel trims,housing sizes.I studied reams of charts for weeks and went full circle by asking the guys with runs on the board for advice.Guys who use the same motor etc.
These Garrets can be purchased new for around 1700,sometimes less.
Sites I found useful-Precision turbo and engine [u.s]
Ray Hall Turbocharging [Aust]Turbotech [aust] A google search should do it.Get ready for a headache.
Seems the most common problem is going too big.People read "capable of making 700 hp" they dont read "700 hp available after 6000rpm on 2.5 litre" you know what im trying to say I hope.

i'll check out the sites you mentioned, thanx for those.
My car which i imported from Japan was used previously as a drag car so i guess the huge TD07 was suitable for there use but clearly not for my street use.
I've made a definate decison now though to go ahead and chage my turbo and think it's gonna be something like the GT35 or GT35/40R which should suit me perfectly from what i seemed to have learnt from various sources and peoples suggestions.

Isn't a GT3540 about the same size as a TD07 but BB. In which case, the lag difference will be a bit better but I wouldn't think it would be a huge improvement.
I would be looking at a GT35 at the biggest by the sounds of what you are after.
I don't know how much power you are going for exactly but I was talking to a guy who runs a GT2530 @18psi on his auto 1j and it made 247rwkw and that would be a lot less laggy than your current turbo.

oh ok, i didn't think it was but i will suss that out cos obviusley if it is the same size then thats not much good. I assumed that the GT35 and GT35/40 would be pretty closely matched but i'm not the clued up to be honest. I have a mate who has a GT35/40 he's selling for about a g but i won't go for the cheaper option if it is the wrong application. I'm currently making about the same as your mate 245.9rwkw @13psi but as previously mentioned it's pretty late in rev range when your really feeling the pull. I'd like 250-300rwkw but with that coming on a hell of a lot earlier. From what i've read the GT35 can reach full boost by 4500rpm, thats when mine just gets started lol. So the td07 isn't BB then, i thought it was by the way the comp wheel seemed to spin by giving it a push spin.

I don't think any of the trust turbos are BB.
If you want around 300rwkw I would be aiming for a gt35 with the .63 compressor AR. It shoud support that power level and be pretty quick to spool also.
I didn't make 247rwkw, that was a guy I was talking to.
Apparently, my HKS ta45s 1jz running 15psi is making around 210rwkw through an auto. I have some stuff to sort out electronically but I would like more power out of it. It is rated at 650hp max.

A GT35R is just a renamed GT35/40.
I find my GT35R somewhat laggy on my 3L 1.5JZ with useable power only available from 4000rpm!
On a 1JZ, I wouldn't expect too much to happen before 4500rpm from a GT35R.
A GT3037/GT30R is much better suited to a 2.5L than a GT35R imho.
