I have spent hours searching thru B20Z related threads, and I can't seem to find the answer to this question. I did learn a few things, but I'd like to know, how much power does a B20Z make when modified?? Has anyone ACTUALLY done tests on a car that has a B20Z swap?? Specifically, I'm looking for expected power from a B20Z with a BLOX IM, Crower 403 cams, DC Sports 4-2-1 header, AEM CAI and a adjustable FPR, all being controlled by the OBD-0 ECU found in a 90 Teg... I know stock B20Z "should" make 146HP/133TQ, but I am concerned how much baseline power they make when being used by a old-school B18A1 ECU and a bunch of bolt-ons that I can't find actual performance data for. Yeah all those bolt ons make power, but how much is what I would like to know... FYI, I need as much torquey, low-mid range NA power as possible for my daily driver 1990 Teg AT. I need a automatic car, but since it needs a new motor, I would like to put in as much non-VTEC NA power as possible.... Anybody have any ideas?? I see some people are not happy with their B20Z swaps, although they are "probably" bottle-necking the motor with either a crappy IM or headers...I dont really know...please help!!
