iirc, the Z33 HR parts fit on the 370z(like the intake manifold, exhaust heads, ect.) so if it works on a HR 350z, it technically should work on the 370z

i am not entirely sure though so if i am wrong, someone please correct me

You would spend all that money for looks? What if this robs HP? I'm still skeptical until proven otherwise.

^ agreed.

Hoping this works out!

People buy 5k + body kits... and 4k+ wheels... whats the difference.

I'm just saying if I got all of my desired mods and my car looking the way I want, I'd do it in a heart beat.

edit: pending it doesn't loose horsepower. Time will tell.

I believe you are correct, I'm just thinking for those who may not know that so they don't get confused.

Because based on that idea, this could technically, potentially, fit on a 350z HR motor as well, correct?

I was just making sure that it wasn't a typo.

Interesting. I hope the gains are worth the trouble. Subscribed =)

I wonder how much room there is between the hood and the top of the manifold. I know the front brace will need modification to fit, but is there even enough room available?

With the brace out of the way, there's a fair amount of room between the stock manifold and the hood. I'd say probably 2-3 inches.

No I would not but it doesn't hurt to show some encouragement and interest, especially since this still in development. Plus it looks killer, and I'm leaning towards it being horsepower positive rather than negative.

You can definitely make positive horsepower gains with a forced induction kit.

as some of you asked for a weight comparison I bolted together the stock upper and lower Z34 manifold vs. the now welded lower GT-R/Z34 Adapter and R35 upper plenum.

Both units are completely comparable as all other parts like TB, fuel rails, hoses, bolts, etc. will stay the same - we only weigh the 2 parts that differ !

The outcome suprised me more than I expected because as you can see in the pictures the scale shows exactly the same position for both - 6.5 kilogram / 14.3 pounds !

so at least we are not going heavier

Nice work!!

ZBro16 · 04-23-2013, 09:33 AM

sub'd. nice work.

ChrisUR · 04-23-2013, 05:25 PM

today I port-matched each runner on both sides (upper flange and lower flanges) and grinded away any welding ridge. The flanges are 100% gasket-match so there are no edges disturbing the air flow !

next step is test-fitting the whole assembly with fuel rails, throttle bodies, etc. to check for strut bar options and general fitment.

then I will powder coat the GT-R Adapter and it should be ready for final installation and first engine fire-up
