Hi all. Right I have a couple questions. There are 2 engine codes for my car. And they are SR20De and Sr20DE. First question is thow do I find out which one mine is. And what is needed "if it can be done" to make my engine the same spec as the Gt version? If anyone has any info on this it will be much appreciated. My car is the gx version and I assume it is the 130bhp model engine but can I make it a Gt engine for the 150bhp???? Many thanks in advance people....
