Engine to 20v MAP

Assuming the engine needs to be changed then the following is recommended: -

• Japan and South America only 

• Toyota Corolla Levin / Trueno 

• AE111 (GT-APEX or other variants)

• 4 cylinders in-line 

• 20 valves (5 valves per cylinder)

• 1.6 liters (1587 cc)

• twincam  (DOHC = Double Over Head Cam)

• 4 throttles 

• with VVT (VVT vs. TPS a 1/2 smart system)

• running on MAP - vacuum sensor (D-Jetronic) 

• aka "Blacktop".

Why this engine is recommended?

It's platform is A Block, which sits into all AE86 nicely and 100%, no mounting change required. In the case of KE70 then the only extra thing needed is the AE86 engine's cross-member. Or one from the AE70 is also useable. See Upgrading Power Steering

Please remember to transfer everything from the half-cut into the project car. Throw-away all the old wiring looms and use all wiring looms from the half-cut. Modern EFI system is proofing more and more complicated and often their grounding routes makes them highly sensitive towards EFI operations. It is suspected that the current (amperes) passing through the different routes is also part of the EFI's ECU operations.

Now that the engine is decided, we'll move on to see what else are needed.
