Ok, I will start off by apologizing for my post. I recently bought my first Z32 and I am learning about the VG30 engine. I migrated from an S130 (which I still have, just going thru an RB25DET conversion). With my apology out of the way, my question is in regards to the intake plenum. Are they the same for both the N/A and TT models? Same with balance tube? I have done some research but have been unable to find anyone with a simple yes or no answer. I want to pick one up so I can get it P/C'ed. Thanks all.
