Here is my setup, I've got a b16 99 civic Si head that's got s2 valves with dual valve springs, turbo cams, ( don't have turbo on yet) and I have the b20z block with stock internals. I've got a chipped p72 ecu that came out of my friends b18 vtec civic and he had the chip tuned for his setup, his ecu in my car make it idle pretty rough. Makes it lumpy/choppy then when I start driving it does good. I believe his ecu is making my setup far to rich. Fucking sucks cause were I live there is no dam dyno. No way to tune my car. I know there is chrome, hondata n what not I just don't have a laptop or skills to street tune myself. Next problem is when I step on it (throttle 35% or more) the transmission, my assumption, makes loud noises like a rock pebble is flailing around in the transmission then sometimes it's like what ever it was stops till I shift into next gear? And my main big problem a Pretty dam big oil leak from the left side of the head, one leak is coming under the vtec solenoid and runs down the front of my block, the other leak is coming from the back left of the block and it's a stream of oil. Had the b20 head gask on then heard I shoul be using the b18a ls head gask. So got the b18 gasket new, put it on with arp head bolts, had the type r head studs in before. And the fucker still leaks same amount do
Same areas. Let me know if you can help. Thanks
