My friend and I put headers on my car last weekend. Took us 4 hours as well but we had a lift. It really wasnt that bad, even got the heatshields out intact. Once the bolts are out of the driverside one, flip it upside down and it comes right out. The only hang up I ran into was that neither o2 sensor would come out of the stock headers and got damaged.

I had an idea the other day. It is a lot faster if you loosen the header bolts a few turn each, then just remove the studs and bolts in one go. You have to take them off on the driver side anyway... Its a lot easier reaching in there with a 1/4 ratchet than it is with non ratchet hand tools... Just an idea

Maybe my header studs were just really loose, but I remember taking them off was really easy with a 1/4 ratchet. I did no even have the tool of the star shape, i just used a small socket that fit over it pretty tight

So there was two people. Makes a hugh difference. I have a lift also.

Man shorties must be way way easier.

We had three people doing the longtubes, didn't change much. It's a long and grueling task that you have to take very slowly if you don't want to muck everything up.

I assume. Only thing I know about the LTH is the extended O2 that takes time. But shorties are just bolt up and attach test pipes. No clearance issues. Mmmmm. Now that I picture it i can see how bolting up the LT would be a pain. Especially the bottom bolts and bolts in the rear being the pipes are long and most likely in the way.

Exactly.

Add in to it that they're ceramic coated and you're warned over and over to touch the coating as little as possible and to even try to install it while it's inside a damned plastic bag... Yeah.

And I actually have to take mine off so I can wrap them and put them back on to get my under hood temps under control.

Going to be awful, since I don't have a lift this time.

Z1 just posted up dyno results of a 350z Nismo with the soon to be released Z1 headers and full bolt ons making 322WHP.... pretty impressive.

Tomei Z33 ExPreme TI Catback Exhaust @ Z1 Motorsports - YouTube

I saw that today on Zatlanta...it's ridiculous how Z1 is able make that much power. I cant wait for the headers and some other non-engine work that might give us more power.

Results as promised

Any dates yet?

Where is Tomei on the 370Z stuff anyway? I like that exhaust on the 350. /threadjack

any updates?

I've got money burning a hole in my pocket!
I'm trying to hold out for these....

I wonder of the 350 headers would be good on the 370.. The momentums were for the 350 after all...

With the amount of ppl interested in these headers, Z1 should have a group buy for when they're released ;)

Not understanding? The Momentum headers from the 350 work on our 370. That's current what I'm running. And the numbers are just as great. That's what this whole thread is originally about. Plus I heard the Z1 headers will be out soon enough. So there coming. You guys have to understand business along with finding a good manufacture to work with to help Z1 produce such a great product. This mod just blew up overnight with short supply. Just know Z1 will provide a great product that's trouble free.

I think he meant to say "I wonder if other 350 headers would work".

To that point, I think the Momentums were very oversized for the engine they were originally designed for, and have a very nice collector design, so I'd be pretty surprised if other 35DE headers get any gains. A lot of them will absolutely fit (I tested some DE long tubes, fit fine with only minor adjustment to a heat shield needed), but they were awful, performance wise.

That is what I meant to say thanks for clarifying - type like crap on these smartphones. Was curious if other 350 headers could work but you answered that too, much appreciated!

I don't think they are very oversized. They were designed specifically for use in their turbo kit. But you are right, with no turbo they are pretty large

The dyno i posted earlier was the numbers for the momentums with cats.

Yeah most the headers won't do much. As stated the momentum headers were made for turbo on the 350 with the momentum turbo kit for faster spool times. Better air flow for us! All the headers from all z34 and z33's will are interchangeable as long as you use the cats from the same motor. Actually a few friends just installed the OBX long tube headers from a 370 into a 04 350z DE. Said they went in smooth....well as smooth as headers do lol. For the DE guys, its an upgrade to swap to the 370z stock intake manifolds.

Man, a DE or, more likely, a RevUp with an HR/VHR mani (Prolly HR is better since spinning to 7500+ isn't smart on a DE or RevUp) and PPE headers coupled with some aftermarket cams...

Holy moly. That's probably a 320-330+ WHP N/A combo for a car that came stock with ~230-240 WHP at most...

This article is from a company that did a custom step long tube header setup, and larger intake manifold and only did 272whp on the DE.....but look where they ended up lol

Nissan 350Z VQ35DE Engine Build - Modified Magazine

Yeah it's impressive, but they spent as much as a V8 swap or TT kit would have cost them, that's always the rub about these hardcore N/A builds.

I think if they could get from 220ish HP stock to 300+ with just intake manifold, headers and cams, they should probably count their blessings and enjoy it lol.

Z1 posted on facebook about 6 weeks away from the headers. Just FYI guys!

Did they say anything about the price??

anyone know if VQ35/37 headers fit on a VQ40DE?

Nope..

So if we get the Z1 momentum headers and the ART pipes made for the 350z, they would line up perfectly with the CBE?
Guess I'll have to wait until these come out before getting ART pipes.

Z1 is making the headers to fit the HR so you don't have buy new cats for the DE like original Momentum headers. Friend with the OBX headers from the 370z on his DE went in for a tune today and put out a whopping 252whp/240tq..... looks like the DE isn't as bolt on friendly Shovelman lol.

Hmmmm..........Ok, what's on your mind?

not all z33 headers will fit a z34 and vice versa.

That is correct. Rob at Z1 said that they tried Tomei HR headers, but it didnt fit.

I also heard that pricing might be in the $800 range...but take that with a grain ofmsalt.

I replaced my mustang with a frontier! It's a va de motor, so I was hoping they night work

But would it work with 350Z art pipes? Waiting is so difficult.

Confused.

The Z1 headers that people are waiting on will be able to be bolted on a 370 straight up? or there's something else that needs to go along with that?

Agree, and will they work with my FI test pipes? Also all this talk on gains, is it even worth it? You guys are starting to confuse me here.....

From what I understand, Z1 is copying the design of the momentum headers from the 350Z, but will alter it so it will mate with 370Z cats/test pipes.

Ok what about gains? Some people are saying big gains and some are saying very little and not worth the money...
