Quote from: Kash_;601389t04z has a slighty bigger wheel then the t04s.... but both good for 500+ hp... t04z are Â£Â£Â£\'s!

Been in a similar boat myself buddy. I managed to bring my selections down to a T04z and GT35r. In an ideal world a GT35r would have been my choice but managed to find a good secondhand T04z for sensible money so couldnt say no.

T04z is also roller bearing and water cooled which im not sure the T04s is, so spool up should be quicker on the Z.

the T60-1 is also water cooled

I know dude, Iâ€™ve had a lot of interest but no oneâ€™s committed.. I think the price is reasonable for a full kit considering the exchange rate but seems everyone wants too much of a bargain lol

I run GT42r on mine. But mine is a totally different set up to what your looking at.

I run half bridge, 4 x 1000cc injectors, 044 external pump and RE uim.

Dont even bother with a GT42 unless you have half or full bridge. I get boost from 4k and full boost by 5.5k ish as i run a 1.28 rear housing so its the big one. If you want to go for a GT42 then get a 1.01 rear housing as this will reduce lag but then your egt\'s will go up and up. Saying that im only running 1.2 bar. The GT42 is worth it when your running 1.6 bar plus really to get the most out of it. Darren at Whifbitx was using GT42 on his but 2 bar of boost and it used to fly once in full boost and that was with a 1.01 rear housing

Why the big exhaust housing?
Have u ever messured the back pressure?

AshRX · April 23, 2009, 12:16:21 PM

That will be changed shortly to a 1.01 ( they only had 1.28 in stock ) plus a nice little shot nos is going in soon.

Lag? What lag lol

I wont belive u have lag with a 1.28 housing.. :p

But u should messure the back pressure when u change the housing..:yes
If u run 1.2bar pressure, than back pressure shold also be around 1.2bar..

If it is, then u have the right housing..:Thumbsup!

just a weird turbo, you really need to be in mid rev range for it to be in boost, but when it hits full boost there aint a lot that will beat you, but the problem is catch up as the smaller turbo cars can get away quicker as they are hitting full boost a lot sooner than I am

That is because of your big exhaust housing..

U will need much more exhaust to spool up the turbine..
If u get a smaller housing it will spool up much faster, because the exhaust will runn the turbine and not just pass it..:Thumbs-up

I read a post on rx7club forum, that you should tune the car on egt when not on boost..
Then u get more torqu..:yes
