i know theres already like 1001 threads on this already, i've just spent the last hour flicking through them... answered quite a few of my questions, but not all of them... my sierra engine is badly in need of a rebuild. blows no smoke, uses no oil, runs cool, is relatively quiet, but incredibly gutless, rarely reaches 100 and sucks more than 13L/100km granny-style driving onroad (stock gearing, 215/75 tyres). my uncle and i are going to do do the work ourselves, but im wanting to know how much money its going to cost to rebuild it properly properly, as in re-bored, new pistons and seals, etc, getting the cam machined or replaced, whatever it needs doing to it, and where the cheapest or best place is to get a QUALITY kit. ive only been able to find costs for professional rebuilds. ignoring costs like clutch replacement or carby, just the engine itself.

yes, i know a G16 engine is not much more cost and gives more power, but i dont want to replace the engine. being a p-plater its not legal plus at least i know that this engine is in (relatively) good condition.
