On a b18b1, i'm talking about either going LS-Vtec with a b16 head, and just running basic lsvtec probably with the head milled down a bit and running on an Apex'i controller

or

I was thinking about taking a non-vtec head and putting dual valve springs in it, getting the valve job done, a mild port, and milling the head down some, also getting a re-tune with the Apex'i Vtec controller..


Either way, im looking for ~200whp. Both of these routes should get me what im looking for right?
Let me know how that VAFC works on your LS motor lol

No, the LS head is not going to be anywhere near good enough to make 200whp. You will have to have a professional $1000-1500 port job on it to make it anywhere near what a VTEC head is capable of.

Another thing is that VTEC isnt just about head flow, its about Camshaft. The NONVTEC cams only have 1 love, which means you have to sacrifice a really shitty idle and part throttle driving for top end power. with VTEC its perfectly normal to idle like stock and make power to 8500 rpms.


SO in short, no, dont do the LS head, you wont make 200whp or close to it.

A stock B16 head can flow up to 190-200whp no problem. Do an LSVTEC with PR3 Pistons, PRO1s, AEBS Intake manifold and one of my headers. thats your best bet
