Don't yell at me too bad, signed on to a buddy's account so I can get some questions answered. I want to mildly build a motor for boost, I really want to go with B20/VTEC. I've heard that the cylinder walls are too thin for boost and I don't want to spend all the money to sleeve them. So I guess my question would be what would be some other options to get a B20 in good shape for turbo application? Another thing that I don't understand is the wiring. The vehicle is a 93 Si, so OBD1 but the B20 would be a OBD2. My buddy says its just the block and not to worry. I kind of like knowing what is going on and since its my first build I would like to know how to do things. Thanks for any help and hopefully Ill be able to learn.

If you don't want to sleeve the block, then you could have the cylinders posted. It's a process of drilling through the side of the block & installing threaded studs that press aginst the cylinders inside the water jackets & keep them from walking. They are sealed with epoxy to keep them from leaking. I've seen this used on B20 VTEC motors that were built for high rpm, so I don't know how well this would work for a boosted motor...

wouldn't that be the same as putting a block guard in?

Well sort of. The problem with block guards is that they don't really fit perfectly & can cause more stress than they prevent. I have no personal experience with this stuff, so all I know is that Larry at Endyn Racing Engines says block guards are a no-no, and uses posting on his personal B20-VTEC (article)...

hmm...well maybe ill just stick with the LS/VTEC
