anyone know a good non-vtec set of mild cams, that you would be safe with out building up the whole valvetrain...
also for a allmotor B20, would b20 cams or LS cams be better if you kept stock ones

If you were going all motor... you wouldn't go with stock cams at all.

b20 int cam has like 3 degrees more duration than newer (96+) ls int cam. Exh cams are the same or so close it wouldn't make a difference. BTW I think Crower has some mild cams that don't require valve springs and such. HTH

B20, skunk2 IM, stock cams, I, H, E with a B16 tranny with LSD in a 92 CX hatch 13.9????
ive havent driven or took a ride in a b20 yet, i have no idea whta it would be like

It would depend on the year b20 you had. The b20b had a comp ratio of about 8.8:1 where the b20z had somewhere in the 9.4-9.6:1 range, I think. Comp ratio plays a big part in N/A. Stripped you probably could get a 13.9 with good tires and driving even with a b20b.
