The 60-1HiFi will easily work on a 3 liter, but the turbine selection that you would use for a 2.5L vs 3.0L is very different. Plan on changing the turbine section when you go to a 3 liter and use the correct turbine for the 2.5L.
It's the turbine size that's critial for a fun car to drive on and off the track.
PS> this is why I went to a smaller turbine.....
As far as moutning the 60-1 HiFi onto a KKK turbo... call Bob at Turbo Performance (www.turbo-performance.com) (818) 994-7087 If anybody can do it, he can.

J chen,
Unfortunately for you, you'll get many different opinions when it comes to turbos, and everybody has a valid argument.
If it was me, I don't like the high back pressure from the #6 housing. Power drops off too much even if the boost stays up. Also, heat stays in the engine and therefore more prone to detonation (don't know what kind of fuel you're running).
Again, if it was me, I'd run a #8 hot housing or equivalent (that will be hard to find out), and for quicker spooling go with the most free flowing exhaust after the turbo.
Your idea of modifying the exhaust housing might work but I don't think anybody knows for sure. The tuning of the exhaust side of a turbocharger is like black art and it's very difficult to figure it out; not like the compressor (CFM rules).

Hi Toomy,
Thanks for the advice.
Tony is very experience with mods
on the 951. Whatever he advices
should be taken into consideration.
Anyway, if the #6 hot housing turns
out to be physically smaller than the
# 8 hot housing, I will give it a shot
& see how it turns out.
One who never trys will never
savour the fruits of failure or success
& that's where one gain experience
