re. Turbo convertors type 85

[Roa, Greg]

Not that I would ever be disappointed by the power output of my 4kq,
especially not after having spent a weekend driving my Porsche, but what
all is required to do a callaway style conversion on a 4kq?
I know Mr. Gough has done one of these, and I have his old explanation
around somewhere in my e-mail, but I don't remember a final write up.
I have read that the 5k turbo diesel turbo and downpipe have been used,
and Matt mentioned using a k26 from a urq.
Are all of these turbos oil cooled?

What were he details of the conversions you have driven in Javad?

Thanks!
