Yeah you could bolt two turbo SU carbs to a normal SU manifold and run the turbos directly into them.

I have a janspeed twin turbo conversion on my RV8, but I'm fitting EFI now so the two carbs I have are going spare. The bolt directly onto the turbo inlet (suck thru), so the fuel gets sucked into the turbos then into the manifold. I have the pipes and stuff as well, dont want much for them as they're no use to me now

That would be excellent,my engine was EFI but sold on the injection set up,do u have any pics of your instalation just to get a few ideas,i was thinking of having the manifolds coming forward as TVR ones and mounting turbos in front of engine and seting up some sort of ducts to keep the engine bay a bit cooler,PM me if u wish Cheers Stu

The SU's would work very well, but be slow to setup.

Id have definately stuck with the efi stuff, and fitted fuel injection though.

that's all the photos I have at the mo. Taken abotu 18 months ago. Car is now in bits, although the engine is going back in next week so long as I have all the bits lol.

The turbos I have are from a Janspeed kit as fitetd to the SD1s in the 1980s. Uses some fairly meaty Rotormaster turbos, basically a T3/4 hybrid. The compressor is quite big, think AR.70.

They are only running low boost at the moment - 5-6psi. Going to up it to 8psi if I can ever get to fettle the wastegates. Bah!

Sounds fookin mental though on full chat and pulls strong from about 1500rpm!

I have just had a look at the engine picture, and drooled all over the keyboard! That setup would look awesome in my Landy if only I had the time and money!

They might look nice. I wouldnt count on them lasting too long though.

No doubt a cheap Chinese unit. And the ad doesnt really give any useful info as to its size.

if it is in any way comparable to a T70 ( 70mm ) turbo, then a single would be plenty for a RV8. But you would never get a T70 with a T3 flange.

In one sentence it says its a 90mm turbo...then shows an 84mm exducer, which makes the first statement utter crap.

If buying a turbo, I would only buy from a reputable source, and buy a quality turbocharger.

AFAIK, This seller is the same as ss_autochrome...whos turbo reputation was well renowned.

As stevie says, those xspower/ssautochrome turbos are of doubtful quality.
