4AGE 20V or 4AGZE ?

there are so many turbos about it would impossible to pinpoint one turbo as "best"
what sort of power do you want? the toyota ct26 which comes on the celica turbo and gt4 is easy to find and cheap,would spool up mega quick as its only small
there are lots of turbo cars about now so i would look at the most common turbo fitted to cars around you
or choose a manifold from a manufacturer and then get a turbo to fit it

other things to consider are cooling,serious oil cooler required to keep temps in check as the turbo feed off the oil system and the rad system will need an overhaul also

drivetrain,clutch and box are going to need attention if you want it to last long,probably including a new clutch master cylinder,those old seals dont like clutch kicks
