welcome mate, the boiling sort of noise could be the charcoal filter, mine used to do that before i took it out, and its poss lack of boost usely means split boost hose, check all your hoses;) although if its coming from the rad it could be an air lock take the cap of and run it on tick over that sometimes sorts it, if it is an air lock you need to get that sorted as you will end up with a hot spot not good

With so many compound problems on a none standard car i would advise taking it to a specialist to get them untangled.

I would reccomend Phoenix :)

i opened the rad cap before a cold start n once the car was at operating temperature i gave it a little throttle n the radiator blowed out water :shock: .. im prolly thinkin down the line that the radiator is clogged :/ ... it could be the water body or the thermostat but for now my best bet is to take the rad of n chek it out :/ ...
