ok as you know, im getting a B20B swap into my integra and i was wondering what the weak parts of the engine is? iv heard alot of things about the cylinder walls being weak, is this true? gimme all the negatives....

also, what would be a good intake mani to swap onto it?

I got one and I love it, Cylinder walls are weak if you boost, but who needs that when you have a lot of fun with all that torque and a good set of tires. have fun.

 

what about intake mani?

 

Use all LS parts. Intake manifold, ECU wiring harness, etc. The motor is essentially a LS engine with a bigger bore. Everything swaps over from one to the other.

Only real downfall is the lower compression ratio...but I still hang with GSR's.

 

thats actuly one of the reason i wanted a B20B, they have idial comression for boost, lots of tourqe and are cheap =D although i will have to have it sleeved before i boost it still seems like a good platform to start with.

also... if i put my B18A1 intake mani on it, will i see any improvments in hp/tq?

 

if you're saying that the stock compression is ideal for boost, than obviously you're not upgrading your rods or pistons, in that case you're not going to be running enough boost to warrant sleeves. I mean to sleeve an engine and then run factory internals is kind of silly. it seems like you're gonna be running 6-8 lbs on a stock greddy or drag kit, so don't worry about blowing a motor.

Yep. You can use the B18A IM but try to find a B18B IM because they flow better I think. Slight difference but hey probably the same price. Dont go skunk2 until you go Turbo or get some cams. You'll lose all the low end goodness.
