remember an 1.00 AR on a T04Z say is different then a 1.00 AR on a Gt42, the 1.00 AR on a GT42R is much bigger

yep but think a 1.0 on mine is getting too hot for some reason and gettting to much back pressure on the hot side. Managed to get one for a very good price with 1.15 or 1.28 rear housing and they might be able to make the housing for inlet V Band so all good

Good diagram here

[BlitzBoy]

so if went for a proper gt42 instead of the hybrid you have, I reckon the 1.0 you have at the mo would be smaller then the 1.0 that comes with GT42.
I would measure the width of your current exhaust housing and ask TD for the width of the exhaust housing that comes with the one they are selling.
the tial vband connection would be cool

[AshRX]

good plan Batman.

Its coming off tonight so ill measure then. Just have to make sure if i cant get the Tial hosuing that the T4 adaptor works

as mark says, the a/r doesnt mean anything on its own.   the rest of the turbo size has an influence as a/r isnt a size its a ratio.  The 20b is running a 0.96 exhaust on a gt45 and making 470 rwhp at 0.8 bar with no sign of heat beeing an issue.

Some of the \'tuners\' on here will tell you that the garret turbo\'s cant take the heat on high hp applications, especially the GT range.

A split diaphram in the w/g would seriously effect the lag you had, so unless you look at old graphs from when it was working properly or drive it with a fixed w/g you wont get an accurate idea.  

There is somthing to be said about learning from other mistakes.  There are a couple of half bridges running in this country that have both run consistently above 500 rwhp with no issues and they are using T51\'s.  That would be my choice as you can pretty much be certain of the results
