G'day guys I recently purchased a gq and it came with a spare motor which has some water injection system on it. The guy could tell me much about it I've heard of menthol/water injection on forced injection cars but never on n/a motor. It's plumbe up to the radiator pipes and enters from the exhaust port side . I removed the exhaust manifold the see if it was just cooling exhaust gasses but it's not it must be running through the head..
any info would be good
Cheers guys I'll get some pics up soon
