Some of the goodies they are giving away is a $700 Snowproformance water/meth kit. I sure could use it.

Found some more info on the GT20 that Malone used back in the days:

i doubt anyones going to be cutting into their compressor housing, but here is a nice article.

but this is mostly what i wanted show, the comparison of a compressor with surge protection, compared to the same compressor with out

and it says ported housing, but they mean that it has the extra surge protection ports, not that its opened up

i read over this one a while ago, but still a good thing to post in this thread

thanks for adding that so in summation, it looks like its possible to make the 2056 work depending on the amount of 'porting' done to compressor housing. Garrett does not offer an anti surge compressor housing for this turbo, so it would need to be custom. Any guess on hole diameter or how many holes? How would one calculate that? From the map that I plotted before, it looks like creating my own anti surge housing might work quite well as the compressor goes back into operating range at higher engine rpms..

i think its possible too, dave did it with his to4e and that turbo is way into surge unlike your car which eventually comes back in to efficiency

here is how they work, but who knows if there is even enough meat on the 2056 housing to do that.  if u do a google search u can see how alot of companys make the anti surge housings, but man u really need some nards to go drilling in to a brand new expensive compressor housing

im curious about the mercedes turbo, they are 50 trim t3's right?  looks like a good turbo but maybe a bit over spun in higher rpms at 30psi?

i have created a list using squirrels calculator of turbos which compressors look some what fitting for a 1.6,  hx30 compressor actually seems good but only for lower boost numbers.  what does everyone else think of these?

td04hl-19t
td05-14b
td05-16g
td05-18g
k6-2 (not the amd processor i used to have one over clocked and *** back in the day when they were a good processor)
hx30

Problem is, you can't just look at the compressor side. Turbines meant for petrol or large displacement diesels are not gonna work on a 1.6/1.9td...

yes i realize that, but most turbos are in a family of turbos with many compatible parts
