Ofc it'd work. Require some fancy pipe work though. Your RS turbo should be good for around 400 bhp though.

Fair enough mate. Problem is. Live mapping isn't possible on the ST

so this would mean standalone management. Jamsport have a few cars running ridiculously big turbos. You should speak to them.

Pretty sure VXR can't be live mapped either.....

And hybrid will run on standard internals.a bloke called Clive runs RS turbo on standard internals and runs a down tuning map which produces about 360-380 bhp.

The problem is the st pistons make the CR To high. Hence why everyone fits the lower comp RS pistons and rods.

countny say they spend all day tweaking the maps on the astra vxr on rolling roads o well

erm how much does that cost wouldnt it be better fitting forged pistons and rods

so that turbo can go on will it produce better responce that the ko4 turbo that is on it

its easyer tuning my t16 zr than this bloody thing

Problem with the ST and RS is that the turbo is a part of the exhaust manifold so you need to get a manifold made that can accept a different turbo!

Courteney will map the VXR as the god fishys. By removing the ecu and downloading and uploading maps. Making small adjustments and tweaks each time.

Of you've got the money. Go fully forged. With something like the jamsport block mid you could strap a massive turbo on like 2bar are you're talking mega bhp.

Yep running around 388bhp at the minute with standard ST internals.

I'd have an RS turbo over a T28 any day. Easier fit too.

It can be custom mapped, but bit of a pain. There are maps written for RS conversion if you really think you need that turbo size.
