Uses a  single garrett to4z
picked up my hks t04z

Would be good to do a HKS T04Z versus Garret T04Z comparison.

What were the relative prices?

What do the dimensions measure up like?

Did either of you guys get/find a compressor map?

:D cheers :)

ummm rev range is from 4500-9000. Its not laggy really bout the same as 2530's if not bit better.

Hey R32-GTS, first of all congratulations on a great result!

Just a few questions for those of you who know.

Are the TO4Z capable of 700rwhp?

What exhaust housing are you using for the turbo to be as responsive as a set of 2530's?

Would you recommend this turbo for a car that is going to be used predominantly on the track?

I'm sorry if I may have hijacked this thread, just curious since we were on the topic.

Thanks in advance!

Well with a 4500-9000rpm range thats a massive spread.

Obviosuly excellent for track with such a range as that, would be very fast even as a streeter (provided traction)

As per the massive and hotly debated thread about twin vs single turbos a while ago... where some very good points for both came up...

A big single IMO correctly matched can do as good, if not better, job than twins. Ive seen to many cars now that are like this

Main good point for twins tho is "legallity". Something some people dont ahve to worry about etc.

With fuel and boost 700rwhp i think it would get close too with more boost. I dont think pulp will achieve it... but you never know

hey gary i paid $3400 delivered and it never got any customs taxes or GST (which is extremely lucky weighing a tonne and in a huge box :lol: )

i got no compressor maps and what can i measure without dis-assembling it :P

SPECS:

HKS T04Z 63T A/R 0.81

i just measured up a few points with the digital calipers...

air filter inlet outside diameter =104.1mm

air filter inlet inside diameter at comp wheel = 69mm

turbine comp cover from centre top to centre bottom is = 195.6mm

compressor inlet pipe inside diameter = 61.6mm

twin split flange onto manifold with two rectangles (inside measurement) = 34.2mmx50.1mm

exhuast outlet inside diameter at exit point of turbo = 71.2mm

exhuast wheel = 65.5mm

now for simon to measure his up :) or someone with one lying around in storage :)

cheers

Sorry for the late replies. Its a R32 GTR not a gts . The turbo has a .81 rear on it. Its a garrett turbo so i assume its a garrett housing. They cost about $2000.00 now if im correct. Once i get some big injectors 1000cc might see what it does at 2bar. But for now it will stay like this as its a bit of a handful to drive. Still got stock box in it but as far is holding up ok.

Edited by R32-GTS
for the D jetro do you need to change anything besides not using the AFMs?

.81 rear housing whats the specs for the cold side?

I'm assuming this is the same spec as a gt35/40R if not abit bigger.

The t04z is one size bigger then the gt3540r pretty much . Has a bigger compressor wheel and slightly bigger turbine wheel. The housings however are the same size.

Well done poo poo

Like I wrote in the article i did for it, i knew it would crack 600 with ease... time to wind it right up dude!

10.9 with a stock box and a really high mph.. with a decent box in it its going to go mid to low 10's , which is awesome for a backyard built shitter :(

As you well know, all of us send out congrats

Tj

thats an awesome result mate, you gotta be happy with that!

Just a quick question - why did you change to the d-getro? Where you maxing out your airflow meters electronically or where they becoming a physical restriction?

Also where you able to use your old tune from the old power fc or did you have to get a compete different retune?

Hey brad weighed it yesterday was 1480kg without me in it. Has a nismo twin plate.

Turbostyler i changed to a d-jetro because the air flow metres wernt working to well with a single turbo as in light throttle cruise etc. . I dont think 2 rb20 afm's would have had any physical restriction. The maps dont interchange they are different.

    • What copper washer do you guys use on the bleeder bolts? The existing one I have I had no idea where to find it in a local store, I did buy some online but that are only 1mm thick whereas my old one is 2mm+ thick and when I put the new washer out and squeeze the top radiator hose I can hear a bit of air but not with the old one. Does this matter? The new one doesn't leak, but the inner diameter is a bit loose whereas the old one threads on the bolt.
    • Howdy all, after being out a few weeks ago on a spirited drive in my GTR I have 2 issues that oddly have appeared at the same time. Whilst accelerating quickly through the gears all of a sudden i’ve lost power at the top of third gear (below redline around 6000rpm) for no obvious reason.    From that point onwards the car has been running rich on idle, won’t really rev under load without a ton of black smoke and the odd backfire, and dying as a pull up to a set of lights unless I keep the revs up around 1500rpm. In addition when shutting down the car that same night (I was 10 minutes from home) I noticed one of the turbos was significantly noisy on wind down when shutting off the engine. After letting the car cool down overnight it starts up fine, although once it gets to temp the revs start to creep up and down, the exhaust is darker than it should be and it also sounds like it’s running rich (fat note) I’ve put a new set of plugs in it - no change, the old plugs all seemed OK with two of them being somewhat richer/fueled up than the other 3 with 1 being borderline. I’ve smoked tested the intake system via the front of the Turbos, found a split vacuum hose going to the factory boost gauge sender, which I have since replaced.  Also found another leak on the gasket coming off the rear turbo outlet, have also replaced this. After fixing both of these leaks - still have the running rich issue. I’ve also tried another pair of AFM’s - no change here After pulling off the front turbo intake pipes, there is obvious shaft play in the front turbo, which now hisses loudly on light revvs although I can’t see why this would make the car run funny even under idle. I’m curious to know why it’s running rich before I potentially replace/rebuild turbos. The car is completely stock <50,000kms  other than an exhaust. Oil and coolant are all clear. I haven’t bothered with coil packs as it looks like they won’t be the issue due to condition of the plugs. Any help appreciated as I cry myself to sleep!
    • No probs at all. I used to love trying to dig up obscure info for those in need where possible going back 20+ years on SAU.  I did have another look and couldn't come up with any closer match. I'm leaning towards those skirts in your first pic are custom fitments, cut down/extended or from another car entirely and modded to fit an R34 sedan. I would've thought someone in Japan had them and taken a photo at some stage over the last 2 decades but there's nothing. Someone out there must know surely.
    • Welcome mate. Any pics? Even with a DE I'd be well happy if I had that as a 1st car.
