Paul,

One company in South California, its eBay name is "turbos_r_us" could clip
my turbine wheel for me.  There are turbine wheels on his eBay site

clipped

at 5, 10 or15 degrees.  Do you think I should have my turbine wheel

clipped

at 15 degrees?  My turbo is the Mazda 1989 one.

Thanks
Rino

I am not sure that will work. It sounds like it will.
Most people have gone to a bigger compressor.
If clipping works to slow the turbine that would
be a lot cheaper to do. It also sounds like it might
reduce the centrifugal loads on the blades which would
be an improvement. Do you have a sketch on how they
are going to clip the blades? 15 degrees does not mean
much to me.

I see there is a turbos_R_us in Australia.

Do you have a web site for these people in So Cal?
Or an post address or phone number? I can go by and see the
shop.

I will inquire.  To send them my turbo I will need an address.
The reason I would prefer less turbine rather than a larger compressor is
that I do not need or want more boost, less boost would be better for me.
More boost also means hotter intake air.

You will not necessarily get more boost with a larger compressor.
What it does is load the turbine down so it does not spin
as fast. The high speed spin is the main reason they fail.
Temperature has a lot to do with it as well but in our
case it is mostly spin IMHO.

By all means cutting the turbine blades
sounds like a workable plan. Let us know how it goes.
Would be nice if you added a turbine tachometer
so we could get a better handle on the problem.
