How to tell a JDM VG30DE from a US

[darthkril]

Is there a way to tel lthe difference between a JDM motor and a US ??

On the NA, I don't think visually other than the vacuum fittings and other small details about how they hook up differently due to the whole RHD thing. If I remember correctly the brake booster hookups to the plenum are usually the give away.

I know there were some valve difference on the NA's for certain years but not sure which years, pretty sure it would be on the first years for obvious reasons.

If it's the TT's they are a little more distinquishable as the turbos are sometimes smaller on the JDM models and the downpipes are sometimes different from the US market ones.

Anybody else wanna add to this?

thanks for your reply. I am going to be going through both motors and I will confirm that info.
