Should you be considering fitting a V8 1UZ-FE engine and/or transmission into your Supra.

 

The speedometer signal in the early LS400 A341E Lexus transmission is not compatible with the Supra speedometer.

This issue can be remedied using a Speedometer Signal Interface such as this;

Prefferably, avoid the earliest versions of this engine and transmission, which can be identified by the 50042 ECU and A341E transmission.

 

Much less conversion work is required with the later models, which can be identified by the 50350 ECU and A342E transmission. :hi:
