standard erst t3 with a 360 degree thrust bearing in it to help with the load.
spooled up by 3000rpm easy, T2 would shat itself at 200bhp, T25 off a tt spec xr3/xr2 could be used, although manifolds are rare.
probably i'd suggest a cossie 2wd t3.
not too laggy at all and will pull 200bhp all day long, a 0.36 exhaust housing would be ok to keep lag down, but a 0.48 would give less resistance to the exhaust gases, although this would raise the lag a little.

if you have he money, then find a GT28 turbo.
