yep get a sierra or a p100 pick-up and get a cheap rover or ford small block v8,good for around 300bhp!but if you want a cheap little rx7 youll have to keep looking,you can get late turbo convertibles for about £1800 and a early 93 or a 94 turbo for bout £3.5k,i would get a 1.6l sierra dump the engine and box+diff etc.get a cossie diff find a prop off a standard sierra and mate it to a type-9 or a similar ford item,link that to a rover v8 and hey presto youve got a v8 sierra but obviesly its harder than i just said
