i keep reading and reading.
everyone keep saying LSvtec with stock bottom end????
is it stock LS piston???, i read up that u can't use stock LS piston becuz the head.
i have a running jdm b16a in my crx, and i have a full LS motor laying around. so i trying to figure out what i need. (budget build) thx

 

.. whoever told you , you can't use a stock ls bottem end is dumb.

You must keep your rev limit , to the limit of the bottem end.
Which will be around 7200rpms revlimit.

Stock block ls's are fine for ls/vtec's .. upgrade your rod bolts and you should be fair safe to rev as high as you need too.
