Now to properly end any debate and confusion over the capabilty of the B20 vs. and LS, mine has 146whp/137tq with just i/h/e after a dyno tune at mainstream. I am pretty sure I had some bad gas in the tank and I know it had some cheap oil in it and only 80 miles on the swap, so it could definitly be putting out a little more at this point and 150+whp should be attainable with just bolting on a high flow cat (if it is not already putting that out). If you want cheap power without dealing with vtec, go to car-part.com and shop around the local salvage yards for a 1999-2001 Honda CR-V engine (this is the B20Z like I have and the B20 to get). I paid $850 for mine after tax, which is about what you would pay for a JDM B20B, which usually turn out to be the low compression engine that is basically only useful for a turbo in my opinion (they should technically feel about like a b18, just with a little more torque if that is all you are looking for).
stats from Honda in the CR-V:
1996-1998 USDM B20B/JDM B20B 126hp/133tq 8.8:1 CR
1999-2001 USDM B20Z/JDM B20B 146hp/133tq 9.6:1 CR
As can be seen from my results, when properly tuned, there is no debate. B20's rule.
