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

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 :)

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

      Duncan's V37.......race car?

      By Duncan · Posted

      Right, its been a while for updating this car, but I made some small but important progress today. In the end I bought an Ecutek dongle from the Australian distributor Tunehouse (for local hardware support) but have gone with a remote tune from Racebox in the US (because they have done millions of these, and I could not find any tuner where I could access the tune anyway as they are all password locked). The App is reasonably easy to work with, but the PC software reminds me of Haltech's ECU Manager that you need to use with the Plat Pro ECUs, it is a nightmare.  Anyway, I sent the details over, got back a tune file and a request for data logs. I finally got a chance to access a private test track today as they want redline logs in 3rd and 4th, and have sent them back for the first round of reviews. The main difference in the tune is going from 1.0 (stock) to 1.3 bar (19psi), although I'm sure is a lot of other stuff in the background. Keeping in mind this is a dead stock car with 125,000klm, this is what the App's performance test claimed: Before After Interesting to note that both 400m tests had the same terminal speed (158klm/h) but different ETs. And no, the speed limiter seems to be higher than that at 186kl/h. Summary of the key logged parameters for the 3rd and 4th gear runs were: Those little turbos were certainly whizzing at 200,000rpm+.  Also I'm really not that excited about oil pressure 55psi at redline so I think I'll go thicker than 5w30 (nissan recommend 0w20....) and see if that improves it. Other than that (and the big boost spike....) everything looks good as a start to me.

      Just one more post to show the final result and the original "janky" solution for a laugh. Everything feels really tight and no wobbling at all, very pleased 🙂

      R32 GTS (RB20DE) clogged cat

      By MBS206 · Posted

      The hot exhaust light will come on not from just the cat being blocked, but it's just a temp sensor, and it's designed to warn you to not do things like park in long grass.   If you've been pushing the motor a bit, it can cause the light to come on.   Second if the cat is rattling, I'd suspect it's not blocked, but instead falling apart inside.   The easiest "fix" until you can get a cat put back in, is to unbolt your one, bash the rest of the insides out, and then bolt it back in.   For a daily driver/street car, I am in agreeance of put a cat in the car. If it were race car I wouldn't care if it were removed.
