[What is the diffrence between ECR33 and HR33?]

HR33      RB20E         2 litre SOHC NA    

ECR33     RB25DE       2.5 litre twin cam NA

ECR33     RB25DET     2.5 litre twin cam turbo

BCNR33   RB26DETT   2.6 litre twin cam twin turbo  

Basically, one is a hunk of junk (HR33), and the other (BCNR33) is a GT-R

These letters are relative to the cars specific chassis code.

As you can see from the codes above, the ECR33 can be turbo or NA, so choose carefully.

Thanks for that. Now I wont sound like a complet fool when I'm talking to ppl.
