I thought about these turbos mentioned and remembered there is a sight somewhere about comparisons.........I'll find it now
http://members.iinet.net.au/~sayers/biscuits/turbos.htm There is one more tubo they never mentioned its the T25G the only difference is the compressor housing its a .80 A/R compared to the .60 A/R apparently its have one on my car and I have a spare one.
Hope this comes in handy
