first of all no, you don't want to use the pr4. second of all, no, the green sensor next to the oil pressure sensor is not the knock sensor, i don't know what it is, but it's not a knock sensor. you have to tap the block for one if you want to run one. i have seen people tap the block at the bottom hole of the alternator bracket and put the knock sensor where the bolt would be. you really don't have to run knock sensor, i didn't have mine hooked up on my b16 for a long time and it was fine. just use the b18 block you already have as opposed to spending more money on a b20.

 

Bah, I 1-upped you. :P He sells them cheaper on egay.

yes, b18c head bolts required.

as well as a b18c water pump and timing belt. or b18a water pump w/ b18a timing belt.

also might want the vtec oil pump for the higher flow.

LS/Vtec Parts List

 

$215 is still alot for the kit, and you don't get to pay stealthmode.

 

b18c head studs are cheaper than ls head studs, pero b16 head studs are the cheapest, por que?

 

I think I might have to build a ls-vtec for my crx.

 

I would have assumed you already did by your screen name. :P

and then you would need some1 to take that b16 off yours hands.. where you located again
