If its a K11, you can find everything you need in a scrap yard.
Being a 1.3 SR make sure you get the drive shaft of a pre 98 1.3 or any drive shaft after 1998.

The Primera GT is a quality car, get one!! Insurance isn't bad, I'm 24 with one, and insured fully comp, all mods declared, with Adrian Flux for about £550.
Very good car, reliable and comfortable, getting about 36-38 MPG out of it too, which isn't too bad for a big powerful car.
Rip it all out. Fit something aftermarket like Omex ECU, if you're serious speak to our resident tuning Guru Ed. But it doesn't come cheap, you're looking at at least a grand for ECU, loom, fitting, mapping etc!!
IIRC the pulsar comes as standard with a T28 turbo, from my very slim knowledge of turbos, the t2x range uses the same turbo flange, IE a t28 uses the same flange as a t2 and a t25.
Although don't take that as gospel.
