My advice would be to buy a decent RST to start with to be honest. Not worth the hassle and plus it should be cheaper to insure....

 

 

hows Jano going to get your insurance down? Asking people stuff like ''What is it at top wak and BHP'' e.t.c isnt gonna make you too many friends, its chav talk.
The conversions fairly easy, if you dont have much experience then id try and get a crash damaged rst on the cheap and swap the bits over, normally people do this to save money but it makes it far easier as well. There isnt really much we can say to help, just check the condition of the main components before you buy, i.e engine, turbo etc.

 

It'd definitely be easier and probably cheaper just to sell it and buy an RST but as RS Monkey says try getting the bits you need on the cheap and it should be a fairly easy conversion...good luck!
