tbh mate the easiest and quickest way also the cheapest way is the tubby conversion, it drops straight in no problems at all.

its all the same mount points etc, you just need to have the intercooler and everything fitted extra that the n/a doesnt have and also change the driveshafts as the n/a ones arent as thick.

as for your choice of car your rev 4 black over silver 2 tone was actually the 10th aniversary edition they are quite rare so you should just keep it if it is in good condition and go with the engine swap.

.

spend a bit of cash on it and you will have good big power for a pretty cheap price.

a couple grand will see you looking at 300-350 bhp thats including new engine labour and parts
