To be honest it's a slightly moot question. Given how old these cars are, probably the only person who can give you an accurate answer as to how hard these will still go is the person mapping them.

Steve, the gearbox will probably give up before the engine hence why I mapped yours reasonably sensible from a boost point of view.
