Turbo Upgrade / Replacement (MY04/05?)

[2jz929]

Injector duty peaked at 87.7%. Tuning not fully compete yet but it's certainly a much better car than it was.

Yours is making some impressive power now, looking forward to seeing it out at Powercruise. I'll be cruising around in my bros little sr20 ke30 again, but prob not going down until the Sunday for the $100k burnout comp.

I still need to swing you some money for that intake too.

[kiahatsiu]

Don't worry about the intake man.

They say g/sec is close to hp atw.
Assuming this is correct, you are around 178kw atw give or take.

Yeah I've read that but it stems from the US and their dynos seem generous. That was an exception on a cold night, it consistently pulls just over 230g/s. But boost is still tapering to 13.5psi by 6400 do has more in it.

I'm most curious as to what a stock turbo or stock car is able to do as a comparison.

Stock VF38 manages around 210 at 15.4psi at peak power. Makes 173Kw@wheels with a TMIC/Turboback

Sweet, so this turbo is definitely a decent upgrade considering what it is doing with minimal mods on less boost. I don't have a comparison to stock as my turbo was pretty shagged when I got the car.

Is it worth putting a higher flowing air filter in, or fitting the shorter silicone pipe that goes to the air box?

Will have to track down a TMIC/FMIC when funds recover.

Good outcome

I would suggest stock air box with 3" silicon intake (will improve response slightly but no need to change airbox until 230awkw)

G/s is a relative indicator of flywheel hp IF maf resolution is accurate

What kind of torque value are you getting at that level?

My car now has a Hyperflow TMIC and a 1 bar wastegate spring (which isn't actually a full 1 bar which is normal for kinugawa). Its currently at 261g/s, 4.60v maf, 95% idc.

Taking it out to Willowbank Raceway tomorrow night in the hope of running a 13, but realistically anything better than the original 15.1@89 will be an improvement

Enjoy that intercooler, it served me well should be easily a 13 in your car now.

[2jz929]

Cheers mate. Was surprised how easily it fit, just slipped the stocko out and it slipped straight in. Sure is a fat thing too.

That's flowing some air right there

Good outcome.

Good luck tomorrow should shit a 13 in

I predict Low 13 coming up.

I'm not overly confident because these wagons are 1500kg plus my 120kg. That's a lot of weight for a little 2l to move. Trying to get the Mrs to run it instead, that's a 70kg saving haha.
