IMO, b16. its simple-it makes more power, revs higher, and the block is stronger. if you were planning on a build/boost, of course i would side with the b18 anyday. a b16 rex will beat a b18 rex.

In dd conditions on the street, a b18b swapped rex with b16/b18c1 tranny will own a rex with a b16. Now in higher rpms in like 4th or 5th, that's a different story and a better outcome for the b16 swapped crx

you beat me too it. the b16 is very overrated. go give a b18b the si tranny and it will walk a lightly modded b16 any day in the 1/4 mile granted they are in the same car. but just because it makes more peak hp doens't mean it has more potential. look where the b16 makes it's power. in excess of 7K rpms and puts down about 90 wtq. so if your goal is peak hp then the b16 is your motor. if you want more responsive power then go with the b18 and if you throw a turbo at it. hello torque and hp

well the b16 is so a dyno queen. it makes power so rediculously high with no torque that it's worthless in any normal sized car. even on boost they are piss ass slow. then people are like well "i can run 13's in my stripped out civic hatch so the motor must be cool" they fail to realize that you could put a lawnmower motor in a stripped out hatch and still be fast. b16 FTL. there is a reason that 4cylinders with 20 less hp run up well over a half of a second faster in the 1/4 mile than the b16
torque is irrelevant. while i can put 170 lb ft of torque on a breaker bar with my arm, that doesnt mean that my arm turning a wheel is going to be faster than a b16. the b16 is faster because it applies its torque at 8k+rpm while the LS makes its torque, though slightly higher, at the speed of my arm turning a breaker bar(but slower rotation.) the b16 makes more power and is faster. given you will have to rev high to get that power, you will only be in the high revs when racing anyways. everybody says a b18/si tranny will own a b16 but it makes 0 sense. if it makes so much tq and has such a wide powerband, why does it need shorter gearing? wouldnt you want to spend more time in your powerband and less time shifting? any LS/trans combo will lose to a b16. b18b has a severe power loss after 5800/6kish.

I am not trying to argue with you or anything bc you know we're cool, but each motor has it's pro's and con's. It all depends on what you want to do with it. In my book, b18b > b16

same here. i want to know the right answer, backed up with reason. i want to learn.
