Anyone used DM Motorsport in Penrith?

[No Crust Racing]

I'm building an SR20, DM is one of the places I've talked to and as his focus is on circuit racing engines, rather than street/drag like a lot of other workshops I am interested in potentially using him to do the bottom end rather than doing it myself with a friend who's an engine builder by trade, but not experienced with SRs. 

He's mentioned he has Nismo internal testing data from the Super GT cars, and as he has one of them (an S15) and appears to be in the high end circuit space it all seems to check out. 

As it's not a cheap decision and I'm not local to him I was hoping to hear from anyone who's had experience with him.

Enough to warrant having a professional do it as I want it to live. 

Seems he works with bigger workshops with NDAs in place.
