Tones of questions again....

I know that the engine code for a gtir engine is 54c stamped on the block.

How can i recognize a bb engine that a gtir engine? Importante for beacause i dont want to swap the gtir motor because i think its a little more challenge.

Where can i find the wiring harness plan, sheet, map, ???? information to be sure my swap goes ok with the electronics?

It's impossible for you to take a gtir instead of a BB.

The gtir has a 4 trottle body intake, huge intercooler, T28 turbo. That's about it for the exterior of it.

You can use the FSM for the wiring diagram

FSM
what is it.?
where can i buy it, on the net?, at nissan's?

okok factory service manuel...
well i have mine for my sr20de....
but i'd like the wiring diagram for a bb sr20det!
