Re: ls vs ls/vtec (Black_LS_Integra)
See I was in the same situation as you and reading/searching helps a lot.
I'll break it down and if anybody cares to correct me, be my guest.
To get a b18a/b into the 200whp range you generally would need:
**You can get the JDM B20 head if you can find it, it flows very similarly to the b16 head
-port n polish head
-over bore done on 81mm, or get the block sleeved to 2.0L
-high CR 11.5:1 +
-Larger diameter Throttle body + aftermarket intake manifold
-hondata or crome.
Now for a LS/Vtec, the vtec heads are much better flowing right off the bat compared to a b18a/b head.
-then you'll need the usual, higher CR, valve spring/retainers, cams, tuner, etc... but you don't even need to do head work to hit 200 with a LS/Vtec
Personally, it's up to your preference. I am building my b18b NA allmotor because of the dyno charts and the good power it makes and makes more with the JDM b20 head + sleeving to larger bore.
the LS/Vtec when done right can also yield very good results, so just depends what 'floats your boat'
