i got an 1800 (105 bhp) lump with the car attached to it for 200 quid. i am negotiating for an rst lump for ??? quid. next thing i need is an rst gearbox with lsd, what do this things cost normally?

i'm planning of making a 1800 zetec turbo with efi management and the turbo and exhaust manifold from the rst lump. What do i also need from the rst to get it going? i'm planning a low boost pressure in the beginning so i don't need a huge expensive intercooler right away. don't have the money for that right now.

cauz it's my first engine rebuild it would be nice to get some advice 'bout stuf that i also need or stuf that i should left behind.

My budget is (including redoing the car itself) about 1300 quid. What do you guys advice knowing that it's my first rebuild so i don't wanna do a zvh.
