balla Posted March 16, 2012 Posted March 16, 2012 Might have already been posted but can anybody tell me the difference between the 03 engines to the 06 engines. is there any internal changes or only the intakes? Quote
daveparkin Posted March 16, 2012 Posted March 16, 2012 Use the Search function - the answer is out there! The 06 rev-up engines added Exhaust Variable Valve Timing. They also had a higher rev limit. Quote
Lexx Posted March 16, 2012 Posted March 16, 2012 Oh dear God. Do I really have to tell you where the search button is? Or to spend a bit of time searching the forum maybe? You've been here a while, so you should know how to use these functions No intakes we're changed between 03 and 06. The HR engine in 07 introduced the twin intakes and that's a 80% new engine over the VQ35DE. 03-06 main change is higher rev limit, EVVT, and a few other improvements to get the extra 20hp. Quote
Bakes100 Posted March 16, 2012 Posted March 16, 2012 Also LED rear lights, these add around 5whp Quote
