I'd rebuild your DIDA with the GAS unit cheaper and redesigned with 5 year guarantee. In prep for SC, replace fuel filter and belt tensioner. Might want to think about an oil catch can too. If you haven't had your exhaust off before, my want to get those bolts. And get new manifold studs & nuts for the headers... All of my studs came out just like everyone else
