GT28 turbo is fooked...GT30 - How much £ + BHP??
I've gotta send Harvey my GT28 cause its died for some strange reason after just 4k miles 
Thing is, if it gets replaced under warranty then thats fine but if not and I've gotta buy a new turbo, then I'm thinking of going to the next stage, my basic engine spec is:
low comp 7.5:1
long studded
polished and ported head
ahmed inlet cam, std exhaust cam
WRC triple layer head gasket
Grey's
radtec 500 cooler and alloy rad
air 2 air
blah de blah
was running 1.9bar on the GT28 with approx 400BHP
How much are GT30's, can they be used without external wastegate?
How many extra ponies do you think in conjunction with my spec engine?? I was thinking 430BHP????

I remember Mike Rainbird saying not long ago that octane ratings of petrol are dropping so bad that it's becoming very hard to achieve that levels with such a small turbo.
Still levels of Ford tuning I can see here are amazing to me. My car is considered by some a VERY VERY fast car here in Poland, it's very slow in England :-/ It's only problem of money though.
I will have fast one one day

Looks the bollocks tho
You wait till you hear the fookin row that thing will make when spooling up with that ported shroud inlet- will sound like a fookin jet engine

Actually, semi-ignore me 
I was thinking of a different turbo
Compressor side its 100% GT30R, but the exhaust housing is a cossie fitment one (.63 EscCossie or RS500? Not sure) rahter than the usual GT30R hosing with the 4 bolt outlet.
Can only presume exhast wheel is a proper GT30R one, ie 60mm 84 trim
What a/r housing is it? GT30Rs come in .63 .82 1.06 but as that looks like a actual cossie ex housing im guessing .63
Leecavturbo-- Its .60 a/r, not a .80!

Lee, A/R ratio isnt relative to an actual size, ie a .70 isnt necicerily bigger than a .60.
For example, a GT40R has a .58 a/r compressor and is fuckloads bigger than than your one.
