T04z Power Rating

[2BNVS]

im upgrading to a garrett t04z with a 1.15 a/r ex. for my rb25/30

the motor is pretty prepped with everything, big cams the like,

so im not really after a full motor power estimate, what is this size t04z rated at?

i cant find no charts anywhere

cheers...ben.

i reckon its a fair bet to add 100hp... maybe a tad more

[Tex Willer]

I,ve seen 500kw @4 hubs on Dynapack . It was an HKS 2.8 litre.

[2BNVS]

when do u think this will start making boost and when could it peak

motor is rb25/30

big cams 11.5mm lift

gtr valve springs

the usual pistons rods, rod bolts,

whole motor balanced and blueprinted

gtr oil/water pumps

custom plenum

custon hi mount manifold

no afm

just to get an idea

on at 4100

[2BNVS]

ahk sweet thats not bad, would i be better of suited to 1 ex. size below?

or this should be fine, how much power would the 1.00 be rated at compared to the 1.15?

ben...

[paulr33]

no idea, it was an educated guess

[2BNVS]

lol well the td07s that i have now comes on at 4100 so i take it the dual ball bearing design will help it earlier and give me better mid range too

cheers...ben.

[paulr33]

a bit yes, but i suspect the a/r change will counteract that giving it worse resposne

[CruiseLiner]

anyone know the power ratings of all the different housings?

the 0.63, 0.81, 1.0 and bigger?

whats the hks 0.81 rated at in hp, and whats the most power anyone has seen from one on a rb26? stroker or not it doesnt matter, i just wanna see how far mine will go when i wind it up

Man I would hate to wait for that to come on o dear the commondoor is winning o wait here it comes o crap the lights turned red :

lol mine go haha let you have a little lead then wack of we go at 3g

those HKS I have seen around the 400hp mark and with your setup CruiseLiner I would say your boost will wack you at 3500

Brad, i've see 450rwkw or there abours from one

And another has made a bit more than that (if you look @ the RB26 dyno thread)

[2BNVS]

so which exhaust size would be best suited to my rb25/30 to say hit 450rwkw, but as reponsive as practically possible ( i know it aint comin on very early) would the 1.00 make it to that power level?

Just fitted a HKS version same as Brads to a stock auto 2JZ and had a hard time keeping its power at a level the Auto could live with(mid400s was as low as it would go at gate value).Boost was in just under 4000rpm.RB30 twin cam would be much the same
