1JZ Turbo Upgrades?
|

Hey folks,
I'm stuck at work again - bored and wishing I was working on my car.  I had a look at the GCG webpage and got to dreaming of a turbo upgrade for my 1JZ (which isn't even running yet  )
The car is a daily driver. I'm more interested in a good 0-100kmh time rather than a dyno warrior.
GCG sell a standard bearing T04R, cast manifold and Tial wastegate for a whopping $5,500. I'm guesing that would be good for around 350rwkw and I would just have to add a piggyback (not an interceptor) ecu and bigger injectors.
-or-
They have a ct12 replacement based on BB GT turbos with steel wheels, which would let me keep the standard manifold and use the custon 'y' dump pipes I'm getting made. Cost is also a whopping $5,500!
I definitely DON'T want a monster T78 - even though Advan are selling them cheap atm.
How soon would these two spool up onto boost, how much boost could they hold and what would their low to mid range torque be like? What do y'all reckon would be the better option for me?
As I said, this is all daydram stuff at the moment. Onec the conversion is done, my next priority will be building up the A240E tranny for faster launches, shifts and durability. Still, I'd be interested to hear what others think.
Thanks in advance,
Justin

Justin, RPM Performance down here in Adelaide have(or maybe had) a 1jz that they pulled out of a mk3 that has a twin kkk turbo setup on it. Last time I was there the engine was sitting on the ground gathering dust with the turbos and everything still attached. Might be worth giving them a call and seeing if they want to sell the turbos/manifolds etc separate from the engine. Not sure of the number but the website is here:

That 1JZ was out of Ben's Yellow 400kw MK3 Supra. Apparantly it was too laggy? He then opted for a 2JZ because of this I think?
I saw the car and the engine myself when I was down there a few months ago.

Hi guys,
He had the engine advertised in the Trading post for $4300 a while ago. Had apparently spent $2700 recoing the KKK K26's on them. Apparently developed 315rwkW with that setup using a SARD Cast Iron manifold
Guessing that the K26's work really well on a 3S-GTE by itself, I reckon it would be great topend only 
Cheers

A T04R is a big turbo for a 1JZ.
Something like a GT3040 with a 0.86 or 1.06 turbine hsg maybe, if it is for a street car that you don't want too laggy.
I'd imagine something like that should get you near 300rwkw.
The only thing is you need an external WG too, which bumps the cost up.
Is anyone running a highflowed CT-26 on there 1JZ??
I'd be interested to know how it performed.

you say a TO4R is to big with only a 1.00 rear housing yet you say put a 1.06 earhousing on a 3040. and the TO4R will be Laggy?
if you are going to get your box rebuilt, get it done by MV Automatics in blackwood SA, i am very happy with there work. i am running a 3000 rpm stall which with the standard turbs i could hold 3600rpm on the line at eastern creek. if drag racing is all you are interested in the T04R will be fine as long as you get you box done with a bigger stall.
if you are up for a drag beast go the 3040 it has a smaller wheel the fron housing and the rear housing is smaller if you go the .82 option.
speak to brett a gcg i found him very good, but honestly i looked at the mainfold and tail gate and decided to go get a custom job built and a PSR gate. as the tial he recommends i dont feel will flow enough air if you want to run say 9 psi on the street. lower the boost you run the bigger the waste gate you will need to pass the air.
PM if you want celica sue and i will have a chat.

The inlet, outlet and turbine are all smaller on a GT3040 than a T04R.
The GT3040 has a T3 sized turbine hsg where ar the T04R has a T04 based turbine hsg, if two of the samr AR were placed next to each other the T04 one would be quite a bit bigger.
Think of compressor hsg's a 0.48 AR T25 comp hsg is smaller that a 0.48 AR T3 which is smaller the a 0.5 AR T04b. All roughly the same AR quite different sizes!!

what did it cost you if you don't mind me asking / you don't mind remembering?
Tial gates aren't that great.
a 45mm Progate ($750) would be a better option, i've had a lot of experience with these and they are the best value IMO. VeeBand connector is a bit annoying, but other than that, top stuff.
and i reckon that GT3040 that E30-323ti recommended would be spot on, great driveability and response with minimal lag.
you could build a good system yourself for around $4500 with REALLY good parts.

$4500 may be a little cheap.
I guesstimate this, all DIY work.
$200, Steam tube Y-manifold (from the 2 stock ones)
$750, external
$2300, GT3040
$2000, ECU & tuning (prolly a bit cheap!?!?)
$100, IC piping redone (aluminium)
$200, new air filter & piping (most people won't have one with a 4" outlet)
$200, new BOV (2nd hand??)
$5750 total, not incl any fuel system upgrades (if you don't mind running the GT3040 on 10psi)
Could use a SAFC (or similar) instead of new ECU if keeping boost low and not upgrading fuel system, still will need tuning and it is a bit of a waste of a GT3040, 20psi would be better!!

i didn't take into account the ECU, because most people won't want to wire it up and tune it themselves.
spose i shoulda mentioned that...

Cheers Guys,
I shoulda added that I've already upgraded the fuel pump - but not injectors, have a monster FMIC and custom piping and am running a SAFC2 (which I'll ditch if I ever go for a quality turbo).
For all-out power and response, I love the sound of the GT3040. But, how would this compare to the ballbearing, steel wheel high-flowed ct12's?
According to the blurb: "This is a conversion carried out to the standard set of turbochargers which bolt back onto the engine, with only the oil & water lines requiring slight modifications. The package uses Garrett GT ball bearing CHRA's"
It just doesn't say how quickly yjey spool up and what sort of power they can handle.
I'm really not looking for a drag racer or lag monster - just something that will be ultra-quick off the lights and make good 0-60/100 times.
747: I've heard great things about MV, but I don't really want to send my box from WA to SA and wait. I'll either get it done locally, or maybe look into the 'tricked up' A340E that JMS are selling.
Still, this is all dream talk at the moment. I'm still trying to get it all on the road!
Thanks folks,
Justin

box was $2300 from memory.
my ball bearing TO4R was $3000
manifold $800 for parts
HPC coat $250
PSR $650
new dump $200
i have seen a 3040 next to my turbo
1.06 rear on 3040 looked fractionally bigger than my 1.00
