Ok here's wat were dealing with. B18b block with ctr pistons as for the head its a b16 port n polish.. Ok I put the motor in and everything was fine I got the car tuned at mainstream and 6 hours later it was mest up. The car started bogging and died out when I got home.. I cranked it bak up n it would idel fine but when I give it gas it boggs and eventually dies out.. I have chaneged out the spark plugs the wires injectors dizzy even the wire harness. As of now the car turns over but doesn't fire up. I noticed that it almost cranks but whit smoke comes out the throttle body and that's it.. I have done everything I kno wat to do now I'm lost.... O ya I did a compression test and all cylinders were at a perfect 240
