yeah i have a document must be the one u refer to. in pdf

has some graphs etc. the t04r is very insuperior to the t04z regards to responsiveness and boost building capabilities.

i would love more mid range like a t04z but this is the real world!

lol just been out for some 'testing' its great with a launch pulls great through all the gears...

pity williwbank isn ton this weds :D

excelent work.

it seems that your boost control problems are long gone :D

:D il have to pull my finger out and get my motor going!!!

hehehe yes all good. :D

thanks v much for everyones help in that thread.

pity im only running 18psi, i really thought i might have to run over 20psi to make 400kw.

:)

so whens the plan to pump more boost into it? :)

btw love ya gtr mate it looks awesome :)

hehe, all at a time.

im still stock fuel rail, pretty stock fuel system, intank pump.

so we was seeing its starting to get to its limits at the top...

will go and race like this see how it goes, then make some improvements..

:)

Hi WRXKilla well done mate. Very interesting power curve there. The t04r is meant to be very similar to the t04z except t04z is ball bearing . Im thinking there must be more differences then that to improve its response time. I have another graph to post up showing boost pressure might be interesting to compare how they ramp up.

Also that is very good power your making for 18psi at that boost i think im only making 400rwkw's at 18psi. I managed to get a 10.9 with 425rwkw's on street tyres with 1.6 60 ft times . It had more in it but i had to baby third gear in the stock box to avoid breaking it. The box exploded the next day anyway. Start saving for a gearset !

From what I have heard (and seen in the results) the T04Z utilises a much later generation of aerodynamics. So much so that, when HKS asked for upgrading potential for their T04Z version, the Garret enginers laughed at them.

I am busting to find a compressor map for a T04Z, I have a rule that says "don't use a turbo until you have checked out the compressor map" to make sure it does what I want. I don't want to break one of my own rules.

:) cheers :)

I just decided i would try it and see how it went as i thought a gt35r would be slightly too small for what i wanted. The t04z ended up been an excellent choice in terms of lag vs power. Comes on boost sooner then a mates gtr with HKS 2530's but just keeps powering in the top end.

I wonder if there is any difference between the HKS T04Z and the Garrett T04Z?

I believe it is only that "anti-surge" compressor cover ? (ie. the holes drilled into the compressor cover) ??? Can anyone confirm this? :)

Oh, and the HKS label which adds 50kw :)

Edited by Wobbz

I have it on good authority that the HKS and garrett are the same sans the sexy front cover.... this is not normally the case with the similar turbos i.e. GTRS and GTSS or 2530 equiv.....

SK TO4Z you know you want to!!!!! 800hp from a 3ltr? hmmm

oh and Morgs u have to throw up a dyno sheet next week :P

yeah all the people saying they should be similar.

actually check it out.

the t04z is a FAR superior turbo than the T04r. i refuse to compare results. :P

appreciate everyones feedback keep it coming.

but yeah i couldnt find comp maps for t04 & t04z sk, if you can that would be great!!!

R32GTS, thanks for your info, i find that helpful for sure.

thanks

    • Ok I get you. But isn’t the butterfly intake a headache with the +T?  see this is my plan so far but please advise me into the right direction.  Nistune Ecu, 1000cc Bosch injectors, TD05 or TD06 Kinugawa turbo using stock rb25det exhuast manifold, walbro fuel pump unsure of model I think it’s 450/460, spitfire coils and sparks to suit and a R35 MAF sensor and boost sensor.    I was thinking maybe do a cheap eBay plenum $400-500 or try find a stock det neo intake. I think I’d port match it so it’s getting the full capacity but open to advice please.  Thanks 
    • The issue now is the 'fuel cut' while driving, and when it happend, it does not stall. This, I did not test the fuel pressure while driving as I cannot with a fuel pressure gauge. I do have Nistune logs, yes. I have also replaced the MAF Sensor.   Also related to the FPG Fuel Hanger – I just realized that I need a Deutsch Crimp Tool to crimp some cables for the FPG Fuel Hanger. Need to purchase additional cables as the kit only included 2, which are for the float. FPG has not responded to my emails so far since purchasing. I thought about taking it to someone and having it done professionally, but I am reluctant since everyone I took it to messed up in some way.  
    • There's a good German place in Brisbane if youre up for the drive 😛
    • The German place in Cabramatta was rock solid, fresh pretzel cooked to order back then. Then it went all quiet, after all the poker machines were removed, then I believe it closed for good. I did drive past the other week and noticed outdoor lighting a big screen, but no idea what is there now.  
    • Yeah I suspect even if you hold airmass per cycle/cylinder constant if you get too far away from stock you're still going to have problems running the factory tune within the bounds of the factory load scale. Cams, different displacement/rod ratio, etc. I'm just lucky that the GTIII-SS with wastegate boost + CA compliance cats is pretty much equivalent to stock turbos. When I have actual space I can finally get it tuned and modify the fuel system for flex fuel to 100% handle any detonation concerns when cranking the boost to whatever those dinky turbos can put out.
