I have b20vtec, stock b20 block with sleeves, stock b16a1 head, stock PGM-FI intake manifold and stock internals.

My question are..

1. How can I maintain my Frankenstein motor in great condition?
2. What is the rev limit for stock b20vtec?
3. What kind of engine oil that will be perfect for b20vtec motor?

Thanks all applicable ideas are always welcome feel free to tell it..

 

Why do you have a stock block that's sleeved???
1. The same way you would with any other honda except you have to watch your RPM's a little more.
2. I wouldn't rev it over 8k.
3. The same oil you run in any other honda will do fine.

With the way you worded your post... I'd do a little more research on Honda's in general and if you type in B20/Vtec or LS/Vtec in the search you will find anything you want to know.
