Plan a 3S-GTE engine rebuild with phased work across the bottom end, valvetrain, fuel system, intake, turbo and exhaust. The overall budget target is $12,000; the detailed parts plan totals $16,690.
Plan
Decisions & Unknowns
What I need to figure out:
•
Choose the piston bore and displacement.
•
Compare the listed 86 mm, 86.5 mm and 87 mm options after measuring the block.
•
Decide whether to polish the existing crankshaft or use the 91 mm Brian Crower crank, and set the engine speed target.
•
Confirm intake manifold, exhaust manifold and turbo fitment, including the Gato intake and Sora Performance or 6Boost manifold options.
•
Finalize the fuel rail and injector selection.
•
Compare the Prime MR2 fuel rail kit with the Radium Gen 2 rail.
•
Compare the listed 1000 cc and 1050 cc injector options.
•
Finalize valve size and cam and crank position sensing.
Tasks
What I need to do:
•
Finalize the engine specification and parts list.
•
Measure and machine the block, head and rotating assembly as required.
•
Assemble the bottom end and valvetrain with the selected pistons, rods, valves, springs and cams.
•
Fit the fuel, intake, turbo and exhaust systems, then verify the engine setup.
