Got a question. my friend got a b20vtec and he wanted to know if he can do a compression test when the engine is pulled out? we did one on his old b18 engine while he had the engine in, but what about when its out?

sorry, fo a compression test to be accurate, the engine must be at operating temp.
wait! how big is your microwave?

Just rig some leads to the starter. Keep the throttle at WOT. Keep in mind that a cold engine will have lower compression than a warm engine. Just look for variation.
