Well i only brought it in september last year.. Rubbish i know.. Well me an my mate set to work stripped the mani,turbo off and gave it all a good clean up..The Turbo was in good shape with no shaft play so was happy about that.. The standered mani was proper cracked right threw, was supprised at how bad it was.. Old mani.. Old an new.. Befor.. After.. Used all new gasket's an nuts.. Also while was there had a oil filter an oil change, new coolent fitted some new plugs to... Have really noticed the difference with new mani, boost feel's stronger so car is going pretty good... I have also noticed the car does not flutter as loudly as befor, is this because it has a better flow threw mani so does not have such a build up of back presure??? Dont know much about it so if question seems stupid im sorry...
