jspec and US difference
Ok I did look honestly as hard as I could and I couldn't find the difference between a Jspec 13b-rew and the US 13b-rew. The one thing I have noticed was that the jspec has a metal intercooler pipe rather than the normal plastic one I am used to seeing. What other differences are there? Should be a quick question, haha

You wouldn't want to install a post 95 long block due to ecu differences, and there is no difference between earlier long or short blocks. No differences between short blocks.

a simplified rats nest.... honestly the most other than engine management and a few reliability updates, the only REAL difference is the suspension and wheel an tire setups as they have maintained their HP after hitting "280" with a more efficient setup
