Is this for a RB25 Neo or RB20? I should probably change my Car(s) thingy now to suit haha

rb20det... lol yes do change it

[Manuel Kasko]

Changed injectors on my RB25 without taking off the plenum as well.

[Ben C34]

neo you have to take off top of plenum due to top feed injectors. oem gasket comes off no worries.

[Marcus89]

That one is a bitch to change

Good luck

Thanks prob get some mates over so I don't have to do it all alone and to talk shit

Sorry to hear mate, Buy some gaskets and change anything suspect while your on the job

This will be the go if I'm changing that may as well fix the lot

G2.5 is a smaller turbo then a G3, they generally maxing out towards 260rwkws mark. So its about at its limit.

He's right, the graph shown is for a G3, but the intake leak might still be present and causing the 5ish psi boost drop. Fixing it might get him another 10-15kw from threshold to redline, definitely worth investigating.

The link says G3 but that is the graph from the G2.5 on the page. Either way I will suss out any leaks and give it another run soon.

That G2.5, I thought was a high flow. Preload the actuator about 10mms, if it starts to pin then its usually a restriction some where. This one don't have much of boost drop.

Stao you need a new thread detailing each of your turbos and their setups.. perhaps in the traders section?

or does such a thing already exist?

[Dan_J]

also stao,

your new website isn't meta tag searchable/ google submitted as i cant seem to find the new one on google which is meant to have more details on your range then the old website

[Dose Pipe Sutututu]

lol... does it fry tyres when you smash the pedal?

Hiflow of a stock 25 turbo? It has a 3 inch inlet so i don't think so

[hypergear]

Yes it does, because the car is so big and front wheel drive, it wheel spins on the spot with stock tires. lol

Preload the actuator to about 10mms. If you a have a boost gauge, check the pressure drop before and after the cooler, also try a run with no exhaust on.

Time for some M/T tyres? lol

[Cowboy1600]

That thing needs to do a trip to Calder, stat.

[jet_r31]

need to get Grandmaster flash in that one...lmao

cheers

This is for a good comparison of the new ATR28SS1 V ATR28G1 based on the Kia's G4GC engine:

SS1 at 8psi, G1 at 12psi:

ower:

Thin red: SS1 @ 8psi,

Green: G1 @ 12psi

Thick Red: NA none turbo @ 0psi

Boost:

Green is G1,

Yellow is SS1

SS1 at 14psi, G1 at 12psi:

ellow: SS1 @ 14psi

Green: G1 @ 12psi

Red: NA @ 0psi

Boost:

Yellow: SS1

Green: G1

This is an excellent turbo for around the 200rwkws on a SR20det.

[ssxRicho]

So when are we taking it to Winton?

[hypergear]

if you dare to drive it. I don't mind filming.

(btw, stock brakes are almost like no brakes)

[Manuel Kasko]

Putting this out to you hypergear guys

But would a leaking cam cover be enough of a boost leak to cause issues?

Just got a gasket for mine because I noticed how bad it was leaking

[hypergear]

I don't think that would be a problem. I can upgrade it to the latest profile, which is targeted at boost dropping issue with internal gate. PM if interested to go ahead.

Those are a set of CT20 Toyota Supra turbochargers that I've recently done. Those are rated to about 400HP each. Running ATR28G3 CHRAs. photos shown compressor and turbine wheel comparison, profiled compressor and turbine housings, and completed turbocharger assembly.
