Doing a b20 swap into my EG. Need a few double checks...
First off, that old rumor that ALL JDM B20B's have 9.6 compression is just a rumor right? Only USDM B20Z's and the NEWER JDM b20b (99+) have 9.6 compression?? How can I tell I am getting a B20B with the higher compression then? I read the b20 tech but it wasn't too clear... I'm gonna be buying off JDMHondaparts. Hopefully they give me the higher compression version...
I have a b16a in my EG right now. I'm gonna swap it out and put a b20 in. I'm running a p28 ecu rite now with the 95 del sol wiring harness. Not sure what tranny, but prolly the b16a one also (sticker/vin number is missing)...
From what I remember, I'll need:
p74/p75/p06 ECU which are the OBD1 LS ecu's or the stock civic DX ecu. I'd prolly have to get the p06 ecu chipped or something if I want it to run right, but it should at least work for now. Will the stock LS ecu need any chipping to run well? Pretty much gonna stay stock for a while, while I consider b20/vtec or building this b20...
LS intake manifold or the skunk2 one for the b18 motor (same bolt pattern). how benefial will will the skunk2 one be if I'm only revving to 7k? some tell me not much, some say it'll help the motor breathe a lot more... I will prolly add some crower 403's in later if i decide to keep the b20. Also does anyone know if ANY of the b20 intake manifolds will work? My friend tells me some of the b20 intake manifolds might work.
OBD-1 LS wiring harness. My friend is gonna sell me his old one for $50. I'll just take that since I don't have my stock one. Would the del-sol one work (i figure no cuz of the vtec sh_t)? Or should I just spend the $50?
And lastly, I'll need a obd-1 b-series distributor from an LS... I'm assuming I can't use my b16a distributor... Also I hear the one from teh b20 one work (that's IF they even include it)
b18 exhaust manifold since the b16a one will prolly hit the oil pan right?
And everything else such as starter/alternator/etc, I can use off my b16a right?
Thanx for the help, Im gonna pull my b16a pretty soon...

ABOUT THE ECU AND DISTRIBUTOR, IM USING A P75 ECU AND A LS DISTRIBUTOR, DONT REALLY KNOW ABOUT THE B20 DISTRIBUTOR?????? KEEP ME UP TO DATE ON UR SWAP IF U CAN, THANKS!!!!

You'll change the whole B20 to your car? Why don't you change your B16A block to B20 block?If you want to be safe then sleeve the block. I have B16A 1st gen with B20 block ( I think is the one lower compression around 8.8:1).I mill the head 0.75mm. Pretty much change the i/h/e and ignition and coil,also crower stage 1 camshaft. I think already quite fast on my 2200lbs car.Once I try race with my Nissan 350Z (matic with 20" rims) on 201 meter I'll beat by around 1.5 car lenght. And one more thing,I don't think B20B intake manifold will fit cause I'll be to high.
