Chiefgroover Posted October 21, 2007 Share Posted October 21, 2007 Many people are asking me about the T04Z and to date I had yet to drive it in anger. It starts positive boost @ 2K. Pulls nicely between 3 & 4K and the 4 to 4.3K where it reaches full boost is easy to control rather than a mighty surge of power. Exiting a corner in 3rd put the foot down @ 3K and as it reaches 4K it pulls hard but smooth making car control so much easier than with the 4088. It pulls strong on my engine right through to 8K showing no signs of weakness. Negotiating a series of turns was always a tricky job for a big tubbed supra and the part throttle control of the engine in the 4K up area is so good you'd be forgiven for thinking its a V8. This is one special turbo, I am totally happy with. I am changing my fuel pump to the Bosch 044, as the walbros are not doing a great job for me at the moment. It demands bigger injectors though, @ 1.3 bar my 850's will be about 87%. Today I ran 1.02bar on the track, giving it everything it had, believe me when I say it was tremendous fun only thing that was going quicker was a mates Westfield Hyabusa, man that thing can brake Would I recommend the T04Z after todays trial, yes :d Quote Link to comment Share on other sites More sharing options...

RobSheffield Posted October 21, 2007 Share Posted October 21, 2007 You have let us all down When you say the walbros are not doing a great job....how do you mean?! Where was it mapped? Quote Link to comment Share on other sites More sharing options...
Chiefgroover Posted October 21, 2007 Author Share Posted October 21, 2007 Dimitri mapped it, and its perfect. Just cant run more boost atm, walbros are getting weak, so i'll go with the 044 bosch. Quote Link to comment Share on other sites More sharing options...
Chiefgroover Posted October 21, 2007 Author Share Posted October 21, 2007 hows this for a nice exhaust colour? Quote Link to comment Share on other sites More sharing options...
Homer Posted October 21, 2007 Share Posted October 21, 2007 Ernie, Is that a twin walbro setup? How do you know it is flowing less than a 044 setup? The reason I ask is I curently have a single walbro that fuels perfectly well for my setup. Not sure on the next step? What sized lines are being run to the filter?

Chiefgroover Posted October 21, 2007 Author Share Posted October 21, 2007 Yes its twin. Strangely the rail doesnt use the middle point for the return, something I cant understand. So I will convert to the same style as the silver car which was feeding each end of the rail and taking the return from the middle. The twins I have dont use any shielding and are very noisey. I also have re installed the tank feed as it was in the wrong place and had a braided hose inside that stopped the fuel gauge working and eventually must have broke it. It has twin stock filters that are recent. It struggles with reliable fuelling atm over 1.1bar. I have had the 044 recommended to me by a few people. Its bound to make less noise too!

Andyhannah Posted October 21, 2007 Share Posted October 21, 2007 hows this for a nice exhaust colour? Looks like dimitri did a damn fine job mapping that ernie:) Quote Link to comment Share on other sites More sharing options...
Chiefgroover Posted October 21, 2007 Author Share Posted October 21, 2007 Andy, it runs sweet as candy, 28mpg in 6th or 110mph in 3rd, it doesnt matter, its brilliantly mapped. I am well happy with it Quote Link to comment Share on other sites More sharing options...
Thorin Posted October 22, 2007 Share Posted October 22, 2007 I thought the 4088 was a smaller turbo than the T04Z? Quote Link to comment Share on other sites More sharing options...
Alex Posted October 22, 2007 Share Posted October 22, 2007 I thought the 4088 was a smaller turbo than the T04Z? It is. Aparrently it's too quick though Quote Link to comment Share on other sites More sharing options...
Mike B Posted October 22, 2007 Share Posted October 22, 2007 Ash runs the 04Z too... he always said he liked it. I couldn't get this on mine, it would need bigger injectors and a date with an HKS doctor. I will try to get mine on a RR back end of this week.

Chiefgroover Posted October 22, 2007 Author Share Posted October 22, 2007 Alex take note of the following written in June 06 by whitelightening who got the engine rebuilt. "Well she should rev to 10,000rpm now. Someone is going to get a quick car. But I warn you, I want an enthusiast - she needs someone who can handle her." So what was it I did to it on the way home that stressed it so much with an 8K rev limit? Quote Link to comment Share on other sites More sharing options...

Guest CoilSpring Posted October 23, 2007 Share Posted October 23, 2007 Chief, Glad to hear that the Z has such outstanding performance. The 04Z offers three turbine housing sizes to choose from - 0.63 0.84 1.0 which one did you use for your setup ? - Quote Link to comment Share on other sites More sharing options...
Chiefgroover Posted October 23, 2007 Author Share Posted October 23, 2007 I went for the big one! Quote Link to comment Share on other sites More sharing options...
Mike B Posted October 23, 2007 Share Posted October 23, 2007 and the throttle response is ok?? (ie instantanious power when you press the loud pedal at higher rpm??) Quote Link to comment Share on other sites More sharing options...
Chiefgroover Posted October 23, 2007 Author Share Posted October 23, 2007 Once its in the power band its almost instant and throttle control of the power delivery is very precise for a turbo car. Might be different at very high boost, but i can see me ever running over 1.3 bar. A very soild and responsive power band is very solid from 4.2 to over 8K in mine, alough the ported / big valve head may have helped after 7K.

dangerous brain Posted October 23, 2007 Share Posted October 23, 2007 Whats the difference between the Z and the R HKS turbo other than the inlet housing? AFAI can see the internal spinny parts are the same? My car allegedly runs a bosch pump and its sooooo noisy. I think it might be nadged its that noisy. What exhaust housing you running with that?

dangerous brain Posted October 23, 2007 Share Posted October 23, 2007 So in theory then getting a BL double ball bearing turbo spinny parts fitted in the R housings should give you similar power capabilities? Quote Link to comment Share on other sites More sharing options...
