Nissan motorsports HR head convertion

Haulnz · 02-13-2012, 03:40 AM

I was looking at that "Project 370Z" FB campaign Nissan is doing.

Im interested in that HR head conversion they have as option 1.

Anyone know more details about it ? Or even better have done it ?

Haulnz · 02-17-2012, 10:30 AM

I guess that's a no.

I get the sense that no one has done that because the VVEL heads on the Z are an efficiency improvement for a daily driven car. That conversion seems to be intended for all-out power.

this could be interesting, I didnt realize that was possible.

I would vote for the N/A option simply because of the current easy availability of HR heads, I'd love to see the potential! I wonder how they would sort out the electronics though with the deletion of the VVEL heads.

That would be a great option to get a good power bump for FI applications. Heck, it may even prove to be worthwild for the NA track junkies as well! Maybe GTM or F.I. can chime in on this!

Look here for all the details ..

NISMO | VQ35DE Engine Parts

The heads were used on the NISMO RS380 Type C - the 350Z JDM race car in Japan.

I'm still trying to get to the bottom of the engine spec used in the PlayStation GT4 370Z's that ran in the Dubai 24-hour recently, but I suspect these engines either have these heads (the Spec 2) or they are fitted with 370Z heads that have been modified to remove the VVEL arrangement.

My guess is the reference at the top of this post is to the NISMO heads which will flow to 440hp (but the standard inlet manifolding only runs to 420hp - to get 440HP you need a modified inlet manifold).

I have a set of 6 x 52mm throttle bodies that we've dummied up to a HR head off a 350Z engine that was detonated a few years ago, and we are playing with airflow (valves sizes, angles etc) to se how much flow we can get (NA-only). The manifold is built up from Ali plate and tube but is internally polished ...

Sounds counter productive to me.

Any of you guys looking to toss out your VHR heads, send them my way.
