Okay, so based on the info you gave me yesterday, it looks like the paperwork has been fiddled with just to get this car imported.
It's showing as a PULSAR
FNN15 4WD GA15DE 1500 01.95- Or an FNN15 4WD SR20 SR-V.
These come in N/A non turbo form.
Nothing changes the fact that this is not an RNN14 (GTI-R).
It is not a run-on of models with different chassis numbers or anything that can be imagined from that.
My suggestion is that it has had a front end collision and fitted with an FNN15 front cut (firewall, rails and wheel wells) welded onto an RNN14 rear end and RNN14 front panels fitted. Thus you end up with what looks like a RNN14 GTI-R but the FNN15 stamp on the firewall.
Something is dodgy and if the seller cannot provide the CORRECT information, it is a rebirthed vehicle and as such, illegal in most parts of the world.
