G30 -660 or the 770 would be my choice with a a/r around 1.00

Theu do reverse rotation options top which is nice, helps fit turbos in tighter

I seen the G30 straight after I posted
I guess it depends in HP drop to the rotary .
Have measured exhaust port size and taken photos whilst consuming loverly cold Budweiser
Probably best I upload photos and sizes tomorrow sometime

I'd say they're stock size ports. I can't get to mine to compare is I can't fit my melon head between the engine and chassis to check

I have had a squint online but they all show inside of the port not outside
I think FC is different , I think that’s what you have ?
Cosmo ones are bigger so leads me to think they are standard .
Could do with someone who has one on a bench to match them up

Power is nothing without control. Weight is enemy of performance, handling and braking.

Had the dressing changed on my finger today
Feels like I had the op again today / absolute agony
Skin was growing through the goz stuff . 3 days late on dressing change
Ouch and double ouch
Anyways , back to turbos
Need some further expert advice
Pete has gone for this
And is told he probably won’t get more than 400 HP from it
As you can see it’s 475-750
So if I go G30-770 will I max out on the same or is it different as that one has internal wastegate ?
Any help or advice is appreciated

The turbine housing may be a limiting factor on the paek hp from what I understand. A bigger rear housing will move the power band up but should give more hp

Time for more reading for me ....... and asking more questions then
Its not that I’m chasing stupid HP
Just want to make sure the turbo I get will be suitable for this and the Cosmo engine too as the exhaust ports are at least 5 mm bigger on that one
I know it’s going to be 2k for turbo + wastegates exhaust etc

As silly as it sounds for me to say this after a lot of discussion BUT stick the S475 on and get it running and then you can see how it works because that turbo will make all the power you want

Only thing is the boost response as in the spool up will be very lazy maybe, which means torque will be less however on a track I cant see you being below 5000 rpm but I would say once that turbo gets going it will pull hard for sure.

Bigger turbos shift more air regardless of the amount of psi. Partly why you can see bigger turbos or a turbo with a bigger rear housing making more hp for the same psi as a smaller one.

The amount I know about turbos is just a hairs worth of the info available.

Tuning a turbo for specific goals is like tuning an engine with regards to cam specs, and valves lol


As regards for running twin turbos, if I had the cash I'd run 2 of those new g series 35 660 just because it would look mint

And would sound even better brapoing away because of zero contamination between exhaust pulse sound waves
