Less bottom end, similar fuel consumption, for me I feel it is very reliable and more tolerant with tuning than any Nova I ever had.
I think the sleeve/piston on this will probably last longer than a P5 sleeve, but then you would have to change the rod a couple of times to make it last.

I have to say though I've re-cased mine in an old Ninja casing and an OS carb. I had no problems with it last weekend and I finished #9 in the A-main (oddly every single other driver on here seems to always TQ and win everything they enter, could they be a bit liberal with the truth?)

I'm well pleased with it, it seems to have tons of compression.
