Actually it is a RB20DET. I'll be getting rid of the GTR badge on the engine and going with something like Silvia RS-X or Silvia RB

I have Imprezza seats. Yes, HKS Carbon Ti. For the time frame-1987, which is what I'm going for, it would be considered a Spec R since it's following the 200ZR, which was a Z31/300ZX with a RB20DET. But yes, like stated above, I'll be ditching the GTR badge.
