I had the eninge in my car for 4 months now. I decided i want to put my car back to stock cause i want to trade it in and get a new car. I put 4000 miles on the engine since its been in my car. The guys that installed it in my 1999 civic si told me that they do no know the actual miles of the engine cause of it being from japan but they did tell me that they normally come with 25000 - 30000 miles. I am looking for someone with that will swap me their B16 plus cash for the B18C. The B18 will come with everything:: The engine, intake mnifold, exhaust manifold w/ 2.5" collector, ECU w/ wiring harness, LSD tranny. Email me at [email protected] with offers.
