Trust me from experience, do not rush a turbo setup.
Take your time. If you want to do it you won't mind waiting 6 months to pay for everything even if it costs 2k as long as it's done right.
Spending too little and not setting up your system for stability will end if the destruction of your motor.
88 LE helped me do mine to my 94 coupe, RIP as of 8/17/05 due to car thieves, and the turbo ended up blowing out the 4th cylinder. It hauled ass though

but if I could do it over I would have spent the extra 1000 before blowing a motor because you spend atleast that rebuilding it.
