b18c, Ls/Vtec, or B20z2/Vtec ???

[NoWayBack91Si]

Well right now i have a jdm b18c gsr swap in my 99 civic coupe. My piston rings are shot and im trying to figure out what to do. My options are:

-rebuild my current gsr block
-get a b20z2 block for B20/VTEC
-get an LS block for LS/VTEC

Im not planning to turbo or anything. It will be N/A for as long as i have it. Regaurdless of whichever option i go with, when i get a different block or rebuild my current one, It will be mildly built.

Which option is better to go with as far as reliablility and power? which will be faster?

The reason why I was considering getting a different block is because I dont have a spare car. So it would be best for me to have a spare block that will be getting built at a shop while i can still drive my car with the current block w/ bad rings. Then ones the block is done I can take a weekend to pull my motor and swap blocks, etc.

I would appeaciate any info! Thanks

get another gsr bottom end.

What's your reasoning behind that? Just curious

Well, it is a better built motor than the Ls or the b20 bottom end, oil squirters, crank girdle, better balanced bottom end. Plus you would have to spend money for an Ls/vtec kit and plug the oil orifice in the head, and externally run oil to it. Also better compression. But It would also be the easier choice.
