Morning Mangs,
From all reports it is a little beast of an engine, with the earliest VG30DET Redtop (mine) being the pick of the bunch. The heads flow better on the single turbo model, and the latter silvertop version didn't make as much power due to emmissions laws.
However, the engineering team clearly put no thought at all into making it easy (or even just not stupidly hard) to work on, unlike the RB.
It's actually not too bad on the engine out front (oil filter issues aside ), there's plenty of room in front of the engine in the 31 spec engine bay. But having to pull the whole bloody thing apart to do anything is a PITA.
Legend, Thanks!
