Straight B20z swap with all the goodies

There are some flaws:

You'll never be able to spin it to 8K without breaking stuff. Therefore, the 403's are out of the question.

The rest is just basic bolt ons. Honestly, I'd say you're looking at no more than 140hp to the wheels, with stock cams. In order to run the 403s, you'd need forged rods and pistons.

This is getting to be a costly project for very mediocre results. For the same price, you could build a B18C and get something at least a little fast.

BTW- Mugen.

wait a minute, wait a minute here... i'm starting to get different opinions from different people.

i talked with a friend who put a b20b into a 1993 civic cx hatch back and he only had an aftermarket exhaust, the guy ran a 14.7.
another friend had basically the same stuff that i was talking about from above, except he had also a b20b in a crx, he doesn't know what his times are but he's absolutely sure he can kill a gsr hatchback. the torque differences is by 0.2 litres, it doesn't seem by that much, but have you ever try stomping on a b16a off the start and compare that with the b18b? they 'll both come off pretty close in a race if it's thrown into a hatchback civic.

now having said that, if the b20 is basically the Ls engine with a bigger displacement, then how come crower claims that the 403 cams are good to 8000 with after market valve springs and retainers on the Ls motor? shouldn't the b20 be even more of a stronger motor (if you go turbo, the block can handle more punishment)?

i basically have all the parts, all i need is the b20z longblock and the cams/valve springs/retainers
