Warpspeed Posted August 28, 2006 Share Posted August 28, 2006 You could always buy the smaller turbine housing as a spare part and fit it yourself, it is not a huge job. Then you can decide which you prefer. Nobody can tell you which is best, it is really a matter of personal choice.

shonen Posted August 28, 2006 Share Posted August 28, 2006 NICE.....thats a lot of power !! but personally I think full boost over 5000rpm is a bit late for me... How much earlier would the boost come on if it were the 0.61 housing ?

cameron Posted August 28, 2006 Share Posted August 28, 2006 What boost level can the T04z be run at 30psi or does that require the 1.00ex housing? Link to comment https://www.sau.com.au/forums/topic/131666-to4z/page/2/#findComment-2445070 Share on other sites More sharing options...
rb26s13 Posted August 28, 2006 Share Posted August 28, 2006 What boost level can the T04z be run at 30psi or does that require the 1.00ex housing? i think you should do some research cam and get back to me find out all you can abotu these turbo's Link to comment https://www.sau.com.au/forums/topic/131666-to4z/page/2/#findComment-2445854 Share on other sites More sharing options...
Morgs Posted August 29, 2006 Share Posted August 29, 2006 I know of one making big numbers on 28psi (0.81) Link to comment https://www.sau.com.au/forums/topic/131666-to4z/page/2/#findComment-2446124 Share on other sites More sharing options...
Warpspeed Posted August 29, 2006 Share Posted August 29, 2006 hmm sound intresting im looking at buying one but not quite sure wat the go is As a first approximation Rpm to reach full boost is just about inversely proportional to a/r. So if 0.84 = 5,200 Rpm 0.68 would be close to (0.68/0.84 x 5200) = 4,200 Rpm. Of course exhaust back pressure will be a bit higher with the smaller housing, so it will make less power at the same boost, but it will probably not be that much slower on the road, and a hell of lot easier to drive. Go back to where you bought the turbo, and ask them what they can get for you. There are a number of housings available, 0.7 single entry, or 0.68 split pulse may be about the right sort of numbers to ask for. These are the next step down from the 0.81 single entry and 0.84 split pulse that you already have.

fsmout Posted August 31, 2006 Share Posted August 31, 2006 Great result mate and nice turbo choice...! has anyone lined up the HKS version and garrett version for performance and heat produced etc...on the same engine? how would the .68 housing go on an RB26? ie what rmp would it come on at and what range of power figures could you expect?
