Turbo Size Help

[neal1980]

Hi, Looking for some help I need to buy a new turbo for my TVR Chimaera.

Im doing a 4.6 Top hat Single turbo conversion. I bought a Turbo but I cant even get it down the front of the chassis its too big. Its a schwitzer and I believe its got a 1.40 exhaust housing, this is way too big for where I want to place it. Which is in a modified Y piece.

So I know there are some clever bods on here that may be able to offer some advice on turbo choice if I can pick your brains.

Its completely rebuilt top hat, cross bolted, 4.6 all arp. Its on the standard Pistons but I have ferriday decompression plates in there taking compression to 8.1 (I believe figures are up stairs)

I have megasquirt 1 Extra to do the fuel and ignition.

Its will also be intercooled.

Any idea of a suitable single turbo hopefully from a UK company so I can pick it up.

No idea of boost yet but I want it to be suitable sized for around 500bhp as I see these supercharged chims making incredibly good power at relatively low psi on standard compression. And if funds allow I would like to eventually fit forged pistons/rods so dont want to be buying another turbo.

Many Thanks

Neal

There was a twin turbo griff built a few years ago see page 8 of the griff forum on here ,there's also a blue one apparently .i think they used the Garrett turbo,s i would have thought there's more room under a chimaera bonnet than a griff.

That twin turbo griff was a bloody nightmare...Dad was given it for a bit, absoulte hoot but don't expect to power down and keep in a straight line if slighly damp road - well even more than normal.

Wonder if its still alive and kicking..?

Isn't it 'plasticmans'. Seem to remember it was first around some time back, then had a fire of some sort [saw the engine advertised] then plasticman [I think] had it reworked and the newer installation looked stunning. Some pictures of it on here somewhere.

The green one caught fire and was destroyed.think the blue one is still about.

Hmm nope,dont think its one of them, pretty sure it was a BRG colour.
