Gt35r On Rb26

[T04GTR]

There's a few here in SA that have basically just been bolted on.

It appears ~20psi makes a shade over 300rwkw.

I'd assume the difference between 20psi making 340-380rwkw and 20psi making a shade over 300rwkw is nice exhaust manifolds, plenums and a decent set of cams.

yeah. thats what i rekon to. im making atm 307 awkw on a t04z on 20 pound.

to be honest id expect more. but a stock as a rock motor just with the nesasery suport mods. im guessing yeah cams etc etc.

[T04GTR]

hrmmmm water methanol injection. i might do that

Dave your car is weird MORGS old green monster was making 370rwks on 19psi you have the same AR as his T04Z yes.

Crap if my car with 2530s dosnt pull 350awkws i will cry

A LOT of people with the usual gear are getting 370-420rwkw on PULP without even going to Meth

Thats just the usual mods and around 23-25psi or there abouts.

I reckon you have a good number of things to look at if a t04z is only making 300rwkw on 20psi. Its a good 50-70rwkw down on what it should be

I must say is there much variance between the garret and hks versions in overall powerout put nismoid

[Faid]

I run the 0.81 AR T04Z with a built 2.7 engine, cams, 4in exhaust, HKS manifold and i make 450kw on 24psi, thats nearly 1.8 bar. and BTW how does the stocker engine respond to a monster turbo like the T04Z. and how do you keep the old girl alive, dont you have issues with blowby due to older piston rings??

if i hijack this topic my apoligies

[T04GTR]

well morgs and pretty much everyone else has cams at the least. and a built motor with forgies so abit of timing could help.

my motor is still going strong. 170pound across all 6. (apart fron some cool oil leaks lol.

i put it down to oil and oil temp. and a concervative tune. tuners get a litle scared when they find out its a 230k old donk hehe.

so penrite syn 5 or syn 10. two 25 row oil coolers and overfilled oil by 1 litre. (up to the hump on the stick) to stop oil surge.

[T04GTR]

PS its probably read my sig and is spiet ing me for it hehe. also having a fully built motor sitting on a stand waiting to go is also another reason haha.

takes it like a bitch

Not to the tune of 70rwkw i dont believe so.

A few GTR's have been using Garrett t04z's here for a while and those are what im going off.

Not the HKS versions

[CruiseLiner]

my hks t04z 0.81 is making 407rwkw on 18psi and 437rwkw on 22psi with 11.5 afr's, 300kw is very very low from results i have seen.

maybe try another tuner?

[Cubes]

So stock cams CruiseLiner?

A good example of what cams can do is LukeVL's Rb25/30.

A mates rb25/30 made 260rwkw on 15psi with std cams. Lukes makes 320rwkw on 15psi.

[CruiseLiner]

nah no stock anything lol, got the 2.7l jun kit and jun 272/11.35mm lift cams.

the dyno mine was on is fairly conservative to from what ive been told around Perth
