Okay I spun a rod bearing in the d16y8 motor I swapped into my civic a while back. I have recently found an eg sedan with a rebuilt d15b7 that I was planning on buying and swapping the b7 into my car. However being the gear head I am I want more power and I happen to have a perfectly fine y8 head I can swap on the b7 block. However a few questions I was hoping to get help with: First of all which timing belt do I use? b7? y8? Second can I use the obd-2 harness with the p2p or should I swap in the obd-1 harness from the parts car if so what ecu would I need to run? Third the y8 motor I have has arp head studs that the previous owner put in the motor. Could I take them out and put them into the b7 block? Or would that ruin the headstuds? Another side question the owner of the car now mentions that he is selling the car because the cv axle continues to "pop" out of the transmission while driving. The car has lowering springs in the front and coilovers in the rear he says he thinks it is because the car is too low. I didn't think that was possible. Anyone have any ideas? Which tranny has shorter gears the d15b7 or the d16y7 tranny? I thank you in advance for any info you can provide me with.
