I had one a while back good little cars I've just got a colt czt for the same sort of money and it's an awesome little car cheap insurance and tax and it goes surprisingly well maybe have a look at them would be ideal for what you want out of a car
I wouldn't just fire in a new set of injectors and hope for the best get them tested first to make sure they are all working ok a failed injector could seriously fuck your engine
it's finished mate sounds like you have it just the way you want it time to buy a starlet and start again they are never finished and turn the teg into a dedicated track car
