I need help identifying the year of my Gen 1 engine





I have a Turbo Busa in a sand rail and I'm having electronic troubles. Can anyone pinpoint the exact year of my engine based on the number? W701-143082

That link claims that an 01 has "very small cats in the exhaust link pipes" and that is flat out wrong.
Can you get pics of the ECU?
The starter clutch setup was changed in 03 I think, I don't remember how they differ, but they do. 99/00 ECUs are 16 bit, 02+ are 32 bit. I think the later ECU is physically thinner.

They added 2 or 3 more plates to the gears for the starter clutch. I only know this because I purchased one from an 01 and went to bolt it on my 06 and was like oh damn lol
