Poish one, theyre doing ones for chinese peds for like £17.50, i might buy a few and sell them on to people round here for an easy £30-40 profit each time
the thing with tuning is, you need to spend a lot of money and time to make power, there is no such thing as cheap power. those 70 kits are probably a semi decent replacement, but if you just open up your ports on your standard minerelli you will get a nice differnce. is your exhaust port still half round? if so, start with that, make it match your exhaust. on my gt ive spent countless hours with files, dremel bits, sandpaper, polish and brake cleaner. ive spent much money on crank balancing and seals, bearings too. ive weight my pistons and filed them slightly so they are the same weight. all of this is time and money, im still lacking power but now its a carb set up needed. but yeah kinda got side tracked there... my point being, you dont just bolt on "performance" it takes trial and error, or equations and money, take your pick!
