I was reading through the thread and was going to weigh in anyway, though looks like you're very much on the page I am reading from - so I'll +1 with with a bit more anecdotal evidence to support it

The ATR28SS15 would be a perfect turbo for your application. I didn't look into some thing even smaller as it doesn't make that much of a difference in response but did loses quite a lot of power. I'

^ lol... maybe I'll use a 3" intake pipe and add in more bends.. that usually gets the suuuuuuuuuuuuuuuutuuututuutut going LOL. Anyhow, some real world facts to back up the results.. errbody likes ti

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.

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

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.

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.

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.

      GOT SUM's RB34

      This morning I carefully reinstalled the manifold and started looking at a couple of things I need to do.  Heat wrap arrived sometime today so I popped into the shed with the missus dishwashing gloves and started wrapping the first half of the dump and the screamer/plumb back.  Once I do the second half I'll be able to final fit the turbo and exhaust up.  Also pulled the harness out today and started terminating it at the ECU end. A connector is done, just need to run the remaining wires that arent in the harness - 12v, gnd and couple I/O

      Thanks for all the replies! I also wanted to ask if wheels that were fitted on Ford Falcons would fit the 350GTs as well? In the area I'm at there aren't that many options for secondhand wheels and new ones here are way out of my budget. From what I've seen, most of the wheels that are available that were fitted on Ford Falcons have an offset of +33 to +36, with a centre bore of 70.5mm whereas the stock 350GT's ones are 66mm, can't seem to find any hubcentric rings that fit that difference though.

      215/45/18 tyres are probably a little on the low side compared to the factory tyre, it should be closer to a 245/45/19, which will get you about an extra 11mm of height, and should make you speedo read a bit closer to reality. 245/45/19s will be a bit too far the other way and you risk a speeding ticket as your speedo might read slower than your actual speed.  245/40/19s would be correct if you are going to 19in rims, they will give you a similar total diameter to the 245/45/18 tyres.

      That's something I forgot to put in my list. The aggressive anti-squat in R32 is a f**king menace. I still need to decide if I'm going to drag the subframe out of my car and weld in the GKTech corrector kit. The main reason to dither is the need to switch to spherical joints in the lower arm to account for the twist induced in the rear pivot caused by lowering the front pivot. And yes...we do put better subframes in R32s, and I wish I'd gotten an S14 one instead of an A31 when I did the "take off and nuke it from orbit" HICAS delete all those years ago.
