Other day at the strip I was testing the b20 swap it drove just fine to the strip. After the 3 run and driving back the engine had no power at take off then it would "kick" in after reving it kinda high and go then after shifting it would do the same thing. I was thinking maybe a spun bearing or bad rings maybe I dont have my compression checker here I just got stationed in EL Paso and Im waiting on my tools to arrive fro TN. Any input or suggestions would be great. Thank you
