Garrett GT3040.

werent u gonna go the 0.82 rear initially??? y have u gone down to 0.63?

[RS500]

aahhh, don't ask dude.

we were having disputes with the trubo supplier and when we came to an agreement, the dude from garrett said that he'll send down a A/R .82 which should be fine, but they actually sent down the A/R .63, and before i knew it, it was already on the car.

i think it should be ok though as the same combo with a A/R .63 made ~260rwkw on an RB30ET at ~20psi.

if i'm not happy, i'll be sending it back to sydney and asking for a .82.

[Guest INASNT]

where the work being done?

also when u picking up that tape deck and cd player?

[RS500]

my friend and P.E.T Mods is helping me out with the turbo work.

not sure dude, need to try and find some free time.

That was a little bit of interesting information. Interesting being the amount of extra boost required for the SOHC head on the 3ltr to make 260rwkw.

Joel,

i could be wrong about the boost but i think it was close engouh to 20psi anyway.

mind you, this engine was internally standard with no porting or cam.

[Cubes]

Don't quote me but I remember SK saying something about the sohc requiring roughly an extra 5psi over the dohc head to have the same/similiar flow.

Thats why I found it interesting as it appeared pretty spot on.

you're cool dude.

i actually found out from my friend yesterday that the car i mentioned actually ran 18-19psi when it made that power.

also, another car with that same turbo made 285rwkw on 24psi.

i guess the SOHC makes quite a difference to power as compared to DOHC.

actually, my 2L cossie engine (DOHC) made almost the same power a VL RB30ET (SOHC) would make with the same turbo on the same boost, so i'm happy.

btw, the VL i mentioned which made ~260rwkw with the GT3040 (A/R .63) has run an 11.67@115mph at calder park, and fyi, it's a 5 spd manual.

I also find it interesting that MOST if not all VL owners run slicks at the drags where as most of the line owners run regular street tyres.

[RS500]

that's a true point, but it's the only way to make them grip
