Quote Moray "The turbo Pat had on his car was a TD05/06 18G hybrid that was originally supplied to him absolutely ages ago by Mark"
Which part of this turbo gave it the '06' notation ? IIRC the 18G wheel is a TD05 part and the TD06 20G compressor cover would be far too big ! Maybe it was the coolant pipe

Still thinking about it Moray. I think I'll just try the 20G as it is on the 2.35 first of all. I've been getting carried away thinking about larger turbos, and am coming around to the idea that I will only make the back end larger if I have to. It is whether the back end will support 450 BHP on a 2.35. If it will I don't want to make it larger because that would kill the bottom end performance and worsen lag.
Waiting to hear if my theoretically ideal surge free 50lb+ Garrett wheel is available to go in the 20G cover.

Yes.
The wheel I am thinking of is the one on the GT37 page of the following (the blue compressor map which hits 50lb). The T04 housing map looks like it is for a larger compressor housing than the TD06/20G, and the red map is for a larger wheel which is a probably a little big to fit.

What do you think of it?

john, check out the T61 map on the Ray Hall turbo website. Unfortunately the wheel appears to be discontinued, which is a shame because it looks spot on for what we want.

I have the turbonetics catalogue on my home pc.
IIR the compressor wheel is 2.4" inducer (ie large) with 3" outer, but this wheel if available is nigh £200
compressor cover is similar size to gt30
Also, the Super 60 trim wheel in a t04e cover (similar size to td06) was very nearly as good, these wheels are quite freely available and cost about £60 I think

Paul, could you point me to the compressor map you mean - I see T3 Super 60, 60-1, T04E-"60", the first one looks too small - is it like the other two?

Good job on the TD05-06 20G mapping session lately
Naming no names but he is well pleased with the 1 bar at 3200 and 1.8bar by 4k rpm and zero surge Nice one !

T61 top of list here http://www.turbofast.com.au/FlowTS.html
But, not nearly as good as I remembered it! But looking at the same map in the Turbonetics 2002 catalogue, the flow scale is different! The ray hall one seems to have been rescaled? Basically add 5 to the flow to get the numbers in the TN version of the map. I haven't checked to see if the maps on the Ray Hall turbo calculators are the same.
Turbonetics catalogue here www.binaryjungle.com/pdfs/Turbonetics2002.pdf
The GT37 turbo with the T04e cover looks well tasty on the compressor side, now all I need to do is get that mated to a BB bore with the smaller turbine wheel and GT32 internal WG turbine housing. It's the green GT37 map, and from the looks of it, it can run wiht no surge yet provide masses of air.
You can pick up a GT37 dirt cheap from Turbometrics I haven't ordered from them, but they do have a couple of adds on scoobyshop.
