I have researched that the 07 "HR" Engine is streets ahead of the previous 03 model. (Ie. noticably faster) However, I was aware that in 2005, the 350z had a slight tweak in its performance and I was wondering is the difference between the 05 and 07 that great? Is the HR engine just simply the best and anything less is totally worthless?

Basically, I am trying to find a reason why I should buy a cheaper 05/06 over an 07/08. If the HR engine isnt "night and day" difference over the 05/06 then Im happy.

I should mention that I am only interested in straight-line speed. So benifits in handling, ride, etc don't bother me. Although I read there is a problem with oil consumption in 05/06s... is that ACCROSS THE BOARD affecting the majority?

Regards,

Thanks.

 

I would personally go with the HR if your looking into horsepower. The gains are much larger from just bolts ons and a tune. Its overall by far the best engine to be on the 350z. Although I do drive an 06 my engine I would love to have an HR..

 

Well like any car the newer model will have better performance its just how it works. You could always buy an 05-06 build motor and boost the crap out out of it then difference isn't important except cheaper to boost older z's

 

if you have the money for a HR, get it.

 

Test drive both to obtain your own opinion If you can afford the HR, go that route.

 

De is faster.........

 

Take a look at 100% OEM down to the tire. The VQ35HR motor bumped me from #10 to #28. That is a fact.
