Ok, so after much thought i decided to go b series in my 91 civic si hatch. A friend of mine has a CRX with an original 75xxx kms on the shell and under the hood is a 1st Gen B16A with about 45xxx kms on it. So the deal is... for 2500 bucks i get the complete swap which includes the complete engine and tranny, all sensors hasports mounts, shift linkage, ECU, Engine harness from his CRX, unknown short ram air intake, unknown header, and his full 2.5 inch exhaust (i dont recall which brand it is but its stainless steel) The swap also comes with a ZEX wet nitrous kit with a 3/4 full bottle. And the best part is I get to swap it in my car and do payments. We will be starting the swap sometime this week coming up, hopefuly. We just have a job on someones car to do first so we have room in the shop. I will be posting pics and comments as we go through the swap. here are a couple pics of the swap in his CRX now. Let me know what you guys think!!
