the engines will pretty much bolt up to your ride.
for suspension, other than the aftermarket stuff you usually find, you could try looking for the superstrut suspension that comes off the JDM Levin GT-Apex, GT-Z, BZ-R. the nice thing about them is that they come with the OEM 2-piston calipers and big discs.
another option would be fitting the 2ETE (SOHC) or 4EFTE (DOHC) 1300cc turbo engine from the starlet. mean little engine, imho.
