Well I thought I got it for a bargain but then we pulled the exhaust housing off and found the engine it'd be on before (mazda rx3) let an apex seal go and it went through the exhaust housing and shattered the exhaust wheel. I cant go into it a great deal as I am going through ACCC with the shop that sold it but to repair it completely will cost and arm and a leg as trust dont sell spare wheels. So we've tried a compromise and we will see how it goes, if it works great and makes max boost before 3500rpm I'll be happy. But as I said it came off a rotary and they flow a lot more gas hence the bigger exhaust housing, so it could be a lag monster yet. btw: I bought it without the wastegate, the wastegate I bought new and was another $650 or so.
