If you can get hold of one it can be done by yourself. You'll loose around 400-500rpm spool but it will give you a little more top, end not that you really need it Benny. There are some cars that just seem to make a little more power than most for no obvious reasons, yours is one

yes - but it's not going to be a world of difference just changing the housing, and will require a remap etc....

in a little bigger turbos ( gt3071r ) the difference is : spooling = 500rpm later for bigger one power = 25-30hp more for bigger one.
thats what I´ve seen on that 3071r turbo.. so a little less hp difference with smaller turbo I believe.

I'll phone a few place's in the week and see if i can just get a housing
Larger housing will also give more power and torque at the same RPM. The more boost you run the more significant it will be. Its not only top end power.

I would personally go for a 2871R 0.64 over a 28RS 0.86!

that was exactly my choice
I'd seen GT28RS (0.86AR) hit 350bhp and even 370bhp, but I knew I wanted more than that AND I wanted full boost as early as I could, so a bigger compressor on a smaller turbine housing was the way to go
I think I'm fairly close to the limits of mine now (without more headwork), but its driveable, not too laggy and goes like stink at the top end
