800 to put in my 87 turbo mk3

[SupraMan1784]

start small first...dont immediately get a large turbo...it will add power but there will be a lot of restrictions that will set you back...your engine wont bring in air and get rid of exhaust as freely...from no upgrade to the intake or the exhaust, assuming the turbo wont come with a new downpipe...it will decrease teh flow of the turbo, your cooling system wont be efficient enough therefore you will be running hot most of the time...there will be a lot of problems if you dont address the small stuff first...a boost controller and an maf meter are fine...but i dont think you really need them just yet, i say start with some suspension work like coilovers, springs, bushings, control arms, and that kind of stuff or start with small steps in teh engine work, intake/exhaust to increase flow, downpipe, and you will need a fuel management upgrade for running a larger turbo...assuming you want to make a lot of power
