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 1.5 way? There's no such thing really as a 1.5 way, just different ways of explaining 2 ways with different ramp rates. HOWEVER. In any driving in a straight line your 1.5 or 2 or 1.7 way should have no clunking at all. With the clutch fully depressed the diff should be silent (unless it's welded but I'm assuming it's not). Something aint right here.
    • Clutch is a spec brand, new clutch system,( PP, flywheel, friction disc, etc. pull type) installed 100 miles ago, with no problems.
    • looking for some help and maybe some insight on others experience with a new LSD. R34 GT ran and drove beautifully, but always alot of grip loss due to the open R200 rear end, so I just installed a new 1.5 LSD way into the stock open R200 for a ER34. Simple. Everything seemed right. I test drove for the first time this weekend. as I started to back out the garage the first time slowly with tires straight it sounded and felt like I had a loose or half disconnected drive shaft...that was clucking around loose and shaking entire vehicle, and making it feel like the trans clutch was spontaneously slipping then grabbing very roughly while just letting out pedal slowly. I backed it out went to pull forward with the same noise, shake and slip grab feeling with hesitation, I turned the tires to back out more and then pulled ahead some same thing but worst because of added wheel resistance (which that I expected) puzzled … pulling it back in checking everything over and finding nothing wrong, I tried it the next day. same thing, couldn’t believe how it shook everything again making a terrible noise and making it feel like the trans clutch was slipping and grabbing, but I got it out of garage into the driveway, got it straight, drove forward and then reveres a few times in a straight line everything shaking , causing what felt like clutch slip and grab every time, sounded like right behind front driver tire and I could feel it in the floor board with my feet,... worst right when beginning to let clutch pedal out to engage slightly, shuttering and sounding terrible along the way…I managed to slowly get down the road, babying it the whole way, once I was rolling (out of 1st) seemed to be better and between shifts, then clutch felt closer to normal…not slip/ grab etc., but back down to any stop, straight road or turning, same thing. Made no difference if all tires were straight or if I was turning. All other gauge read out correct. with in 2 miles as planned I reached the empty parking lot and performed the break in procedure that came with lsd, essentially to drive in a figure 8 a bunch.  Did this, binding chattering, and shaking the car the whole way. I drove it back home seemed somewhat normal once I was in straight line and past 10 mph or so, and I know it will “bind” on corners and cause some tires squeal when turning especially from a stop, but when I begin to move it still causes what feels like the trans clutch to slip and jerk badly as well as shaking the entire car, and sounds terrible, that I didn’t expect. I used the fluid they supplied with LSD kit and did the breaking, planning to change fluid as they suggest after breaking, but wondering will it get smoother or less aggressive with use? maybe a 1.5 is just too aggressive for normal road driving?   I have a LSD that I put in my 71 cuda when I restored it, with amazing smooth , quite yet effective results. Different style LSD but that ones a joy to drive. maybe expecting too much from this R200?
