I just go done swapping out my B18B for a GSR Motor. However, its been almost a month and I can't figure out why my car does not have any power. I mean it is 80% slower and less powerful than my old motor. I bet you a bike can beat me at any gear. And I have high compression TYPE-R pistons in this baby. I mean motor runs fine with stable idling. The valve train is new and just had a head job from the machine shop. I did compression check and everything was good. Even tested for leaks in the vacuum and found no leak. I also readjust the valve clearance as double check the timing but nothing seems to help. Also got a new catalyst converter and the entire exhaust system from the header all the way to the muffler is new. Matter of fact I even disassembled the pieces to make sure nothing stuck inside. I have AEM cold air intake with K&N filter and its also new. I have 3 different manuals including the HELMS and been sitting on this thing all month. Can anyone tell me what else I need to check for.
