If you wish I have a K27HF that you can try. It worked nice with my GHL headers (which are also available). However, fuel enrichment is recommended because it blows to redline.
I would keep it but I have a T04 flange on my headers and I may go to a bigger turbo. (BTW: i am going to be in the bay area in early march).
