Yes Chad at On3 is a super nice guy! If you call he will take care of you if you really want one. I know a few people running the kit and they are happy. Ive seen 10.70s with the kit on a pretty much bolt on car and driven all the time.I know the guy who owns the company, the kit is proven their are many kits sold and will make plenty of power to split your block down the middle. He has revised the kit as time goes on to curb the problems people encounter, for less then 2500 you can have this kit and supporting mods and a tune make 500+ to the wheels, not bad.
Have you owned one or no somebody that does?well, considering MP turbos are budget turbos themselves and are about $500 brand new and it is a $400 upgrade from the base turbo...that just goes to show how much of a pile of crap the base turbo kit is. $100 new turbo? no thanks.
plus, i have heard alot of horror stories about on3. unless you put more work into it. but its not a bolt on and go with no worries kit.
if you were going with a cheap turbo kit and do a few upgrades, id go with this one and buy two small mp turbos for about the same price.
