Best I can figure at this point is that there are manufactures that make piston sleeve kits for the 2D and 1B motors. I don't know if you have different sleeves, or that is just how they are set up in a 7afe. But were I'm looking, it also mentions sleeve kits for 7afe motors. Maybe you have some kind of hybridization going on, or there is another explanation for this phenomenon.

I'm just going off of what I seen on that site. It also lists them for a 5s. I didn't know the 7afe was an irion block. I thought the 5sfe was though. Why did they make such low performing econo motors iron block? Cheaper, I guess. -------------------- Live Free, Be Happy
