RE: They're here
My buddy has a few older ST's (.15 and .23 I believe) and I have a pair too, that he wants me to make heads for but I havent had a chance yet. I had an original G15 rear intake diesel but I sold it a few years ago.
I should get these old tigre's converted and let you know how they run. There are the 4 of them, sitting in a box in my shop gathering wood dust...
