New to me 1997 240sx

[LivelyZ]

Hey! Just bought myself a 240sx, 1997 , body seems great. It has a Black top Sr20det which he claims was from a s15.. Is there anyway to truly tell? it was just a motor swap with the hardware from the sr20.. intake manifold, air intake, turbo, etc with the 5 spd stock tranny. I think I did alright on the deal, has a few spare parts.. axel, diff, control arms, etc. 200k on the body and somewhere between 60-100k on the motor (who knows?)

From what I can tell around the maritimes theyre harder and harder to find unmolested. I believe it is the LE (sunroom, leather, etc).

Anyway, questions would be, what would be the worth of the car? seen a few on kijiji for 9-11000$ canadian with swaps, and a few that need work with the stock ka24 for anywhere from 1991-1998 from 3000-7000$ . Drift tax?

is there a serial number somewhere on the block to tell me what turbo and motor is in it?
