hey guys, just recently did an engine conversion in my sierra from a swift g13b to a vitara g16a carby after my g13b overheated. finally got her running thanks to suziauto with a bit of help on the wiring and had some extractors and exhaust fitted on by an exhaust shop.
i am having some problems though: first of all there is the tiniest bit of water coming out my exhaust, pretty sure this is not good :S

also, the engine feels like it hesitates sometimes while im driving. like the acceleration cuts out for half a second??? suziauto took it for a couple test drives but didnt notice it, they said the timing is fine and reckon the car runs well for a conversion.
any help would be heaps appreciated,
thankyou.
