Default Smallest turbos for 1800hp 540 combo.

Posting this for a friend with a 540 BBC,(yuk),he's currently running an 8-71 combo but wants to switch to a twin turbo ,blowthrough Domi setup.
His problem is lack of space to fit the turbos, his car is tiny, he wants a max of 1800hp, and water/meth injection will be used because there's no room for intercoolers anywhere in the car. I know the BW S400's will make the power but they are just too physically big, what are the physically smallest turbos available that will make up to 900hp each? I'm assuming he will need T6 flange turbines and can work out what compressor size he'll need from the maps,but I can't find any diagrams of turbo dimensions anywhere.(except MP ,but I know they wont make the power). Preferably not the expensive BB type. Thanks,Taff.

V8, yeah thanks, but what size is a small frame in inches? I need to know how long and wide they are so we can measure up to see if they'll fit.

Any thought to mounting them in the back?

Harry has some pretty good stuff in the 1000 each range.

Steve Morris made 1800 hp on gas with Gordon's 509 cid engine using 2 80mm turbos:

He later (see same link) made over 2300 hp with 91 mm units.

Yeah, I've told him he'll have to wear bicycle clips
Bankbook, I've found the PT88 with a T4 flange but can't see a T6 version,got a link to it? Or even better a diagram/pic? Thanks.

I dont have a link or pics. I did have them spec'd for my build a while back from Turbo69bird (Jeff). Although not commonly found with a T6 flange they are available. Most guys get the T4 because they are using a single set up. They are listed on Precisions website.
