T04 P trim on a 2JZ.....

[strx7]

Has anyone had much experience with a T04 based turbo on a 2JZGTE or 2JZGE -T ? with a P trim exhuast wheel, i'm wanting to know what sized exhuast housing has been used and at what RPM it's spooling the turbo at.

I'm trying to work out weather I should use a 1.15a/r or 1.52a/r on my surf

I'm hoping for around 350-400hp (at the flywheel) on 96 with water injection

Cheers

I have not tested myself but I know John is currently running a T04 setup on his 1.5JZ and I just saw him get 320kw on 11psi. He comes on boost at around 2.5 to 2.7K and it holds it straight through the rev range.

He had a T04E on there previously and now running a T04Z I think. Not sure what AR etc. I can inquire more into this if your interested or put you in touch with him if you like?

Also I *think* Kevin is running a similar T04 setup in his 2J Supra and he easily breaks 400rwkw everytime...

kinda on and off the topic,
and dont have a lot of details yet but,

The guy with our first RWD levin race car has just gone back from his 2JZGTE to the 1JZGTE to drop down a race class,
and was at the dyno the other day in CHCH.

The loss in cc's has meant it's down to only 600hp ATW now, lol
probably at some stupid boost.

if you could just find out the exhuast housing size that would be appreciated.

thanks

Fairly sure it's .90 or .95 as he said last night it's rated at 900hp but when he upgrades to a 1.1 it'll be good for around 950hp.

Will ask him again when I see him. He's working night shifts at the moment so it's hard to get a hold of him at times!

John Had a .70 A/r and now has a .84A/r (well it did last time i rebuilt it.)

Kevin has a Trust T78... hopefully soon to be a Turbonetics T72...

a 1.15 -1.52 is abit toooo big for 400hp... more like 900hp...
if you went with a .58 - .68 that would most probly better...

it's in a 130 surf which weighs 1950kg
I dont care about how much HP it can make, i just dont want the thing on boost all the time, which it will be if the exhuast housing is too small.
I dont care if i dont see boost until 4500-5500 rpm in 2nd gear.
i want 'power on tap' not 'power all the time'

Yeah I was there when it was run, 28psi if I remember correctly. I think running a GT42. It was a peaky curve. Sounded pretty bad ass though.

in that case ... mmm a .96 or a 1.00 would be ok..
but it sounds strange .. you want it to be lazy, normaly its the other way around.

Couple of points...

1.15A/R or 1.52 A/R is an incredible overkill for turbine A/R your HP goals. You can maybe make that with a .48 A/R. You can EASILY make that with a .63 A/R as I have. Also, there is no way you need water injection for the boost you will need to run to make that small amount of power. Why not control boost with an electronic boost controller and give yourself the flexability in the future to change it and use the more appropriate housing?

OR... use your right foot.

My whole vehicle is overkill. Outright power is not my goal. I have adequate power as a N/A 2JZGE for my normal driving duties including towing & speedway. But I would LOVE a extra 100-150HP (or more) for when I'm playing on the speedway track pushing sprint cars and when towing, coming to a hill and being able to sit on 100kph up it with one of my competition vehicles on the back.

I'm not planning on using the water injection as a detonation preventer, i'm using it because with it, i can run more advance and get more power from the same boost. I'm only wanting to run between 10 and 15psi, but i want to extract as much power from it as i can SAFELY.

By the sounds of it I'll start off with the 1.15a/r and see how responsive it is. For sure a 0.4 or 0.6 would make the power level but the thing would constantly be on boost. I'm wanting to see manifold vacuum a 100kph in 5th on the open road at 2000rpm

[4000GT]

Dude, you will make that power under 15psi. Seriously no need for WI.
