4AGE 20V Blacktop Engine Swap Project Diary

 

This page documents the swap of a 4AGE 20V 'Blacktop' engine from a '97 Toyota Sprinter Trueno BZ-G into my '85 MR2. I will try to provide as much info as possible to help anyone who is contemplating doing this swap.

Diary of the Swap

  • Intro - The story of how I obtained it & pics of the half cut before starting disassembly
  • Day 1 (10/14/02) - Removed fenders & hood
  • Day 2 (10/15/02) - Removed dashboard & steering wheel
  • Day 3 (10/16/02) - Removed radiator, lights, & intake
  • Day 4 (10/17/02) - Removed PS pump and AC compressor
  • Day 5 (10/19/02) - Removed wiring harneses & engine ready to be pulled
  • Day 6 (10/21/02) - Just a few pics of the engine before it was pulled
  • Day 7 (10/23/02) - Pulled engine from clip
  • Day 8 (10/24/02) - Continued stripping what was left on the chassis (ABS system, steering rack, etc). Labeled all connectors on body & engine harnesses. Pics of all connectors to come another day.
  • Day 9 (10/25/02) - Finished stripping chassis of calipers & sway bar. Left strut assemblies in tact so that I can roll the half cut around by its wheels. Chassis is ready for the junkyard.
  • (10/26/02-11/06/02)- Have just done a few random things the past few days. Got rid of chassis, messed around with body & engine harness & put together their web pages linked below. Replacement Magnecor spark plug wires were found to fit. Removed injectors and will send them out to be cleaned & flow tested.
  • (11/07/02-11/23/02)- More wiring stuff.
  • Day 10 (11/24/02)- Removed downpipe flange & crank pulley. Magnecors received, injectors shipped. Update: Injector report.
  • Day 11-12 (12/6-7/02)- Dropped 16V engine from the MR2
  • Day 13 (12/15/02) - Started the C56 tranny conversion to work with the MR2 shift linkage
  • Day 14-15 (12/30/02) - Started cleaning & painting parts of the engine
  • Day 16 (1/9/03) - Battery tray removed, clutch slave cylinder rebuilt
  • Day 17 (1/18/03) - C56 tranny adapter piece fabbed
  • Day 18 (1/19/03) - MR2 interior stripped to expose wire loom, ELS# wires tapped, evaporator removed
  • Day 19 (2/1/03) - Engine harness update, tranny parts reassembled, engine bay painted, shifter bushings installed
  • Day 20 (2/8/03) - Just some clean up and attempt to mount flywheel/clutch. Find out I had ordered the wrong set! doh! That delays things a couple weeks.
  • Day 21 (2/21/03) - Proper clutch/flywheel installed, ARP flywheel bolts, 20V engine mounted into MR2, clutch & shifter linkage hooked up.
  • Day 22 (3/12/03) - Parents visited for a week. So that's the reason for the most recent delay. Interior put back together. Interior wiring looms laid in place. Positive battery cable routed from front trunk to the engine bay.
  • Day 23 (3/15/03) - Speedsource SS clutch line installed, coolant system lines routed, 87+ taillights installed, ECU mounted in trunk, ignitor/coil mounted, engine harness connected, spark plug wires connected
  • Day 24-25 (3/27-28/03) - Coolant system finished, AFR gauge mounted, Battery mounted in front trunk, throttle cable extended & new bracket fabbed, fuel line extended
  • Day 26 (3/29/03) - Exhaust system fabricated
  • Day 27 (3/31/03-4/5/03) - Timing belt arrived, O2 sensor flange mounted, car started for first time, transmission dropped to fix clutch problem, Project complete!
