Just to keep any heat out of the lower manifold. I have no doubt it would help things on the theory level, but it probably falls into the same category as deleting the throttle body coolant lines- helpful in theory, unnoticable in practice.

Oh I misread, between the head and the lower mani. Probably not unless you milled the flange.

Yeah, that's too much effort for a difference you'd need lab equipment to notice.

He's making overflow tanks :-)

He asked me what aluminum I'd like a few days ago, lol

so basically, if i send my tb's and plenum to z1, they will port them out just like that?

I don't think he was talking about sending his tb's to z1. Just the core exchange discount of his intake mani and getting the modified z1 intake mani, which runs $300 vs just buying their mani for $595.

AZ responded. Looks like its a way off being busy and second time they've told me they have no idea on pricing without seeing everything. I don't know about you guys but I'm not down to ship stuff, get a reall high quote, then have to pay to ship back. Looks like I'll be finding prices local instead.

I see him online everyday but no response to several pms. I did just get one from them but it doesn't look good.

looking forward for final result

Update.

AZ is out. IPS Motorsports in columbus is in. I stopped in the shop and talked to the porter for awhile. His prices seem very low and we can undermine even Z1's manifold with what I believe can be a much better job!

Also I talked to the tuner. We will do everything for you guys! We will dyno my car as is. We will install the lower mani. We dyno again. Then we will tune it. Then we will install the upper mani. We will dyno with the stock tune. Then we will revert back to the lower mani tune and we will tune off that for both mani's. Then do all that with the TB's.

You will know what power you make with each item you buy and add on and you will know the before and after of everything without someone lying and changing dyno numbers. It will be legit, I'll make sure of it as I do all the motor work!

Stay tuned.

why not go all out and make a good looking/functional upper mani? it would be awesome over the stock plastic box lol

here's a 700whp 370z from this months DSPORT mag i saw.

So, it's a 550whp Z? :rofl2: Where's that DSport shill that claims ridiculous numbers on a stock Stillen kit when you need him?

Cause that mani must cost $700 plus.

That's from a HKS Supercharger kit, of which I THINK only one was ever made.

I would be surprised if more than one or two copies of that manifold exist.

Yeah, that is this car which I think ended up low 500whp on the dyno.

That mani is probably more, it was a one-off to fit the dual SC setup by revyou, unfortunately any manifold project is going to be a huge cost both for the shop and buyers.

easy now i'm just repeating the numbers i read in the magazine lol

also i'm pretty sure the cover listed it as twin turbo'd but its a supercharger system? lol wtf? and i believe it was listed as 731.8WHP

i just want a intake that is functional AND looks good. is that too much to ask? lol :bowrofl:

Yeah, it's just a **** mag with bs numbers across the board. :rofl2:

never read it before but while waiting on food at sheetz i picked it up to check out the Z lol

seeing 700+whp number drew me in lol regardless i like the intake mani is all felt like throwing it in the mix here with all the manifold talk.

It's not bad to read on the shitter, just take 25% off the top on all their numbers. :rofl2:

good to know. thanks buddy :tiphat:

Just give me function. I can't say its offical but the cost of porting these 4 items will be close to the cost of the Z1 ported mani which is just a single item!!

well ok then lol now lets just hope they put down some impressive numbers.

if so then i might have to get in line.

regardless still gotta factor in the cost of a re-tune with this or the Z1 mani. dont really see a way around that unless you self-tune.

Needs to be like for like compared against the Z1 manifold if you want any results you collect to be meaningful.

Z1, whether you choose to believe them or not, has provided such results with their marketing information. You would need to do the same if you want to present the product as superior. Otherwise you're going down the Akuma Motorsports Intake vs Stillen road.

Also, you, or the guy actually going to be making and selling these things, will need to get a vendor account on this site or the site operator will be highly displeased with you.

Good luck! Definitely watching and waiting for results! :tup:

hey now i like my akuma intakes lol

also i ended up putting down more HP than another 7at Z the same day with stillens and a f.i. exhaust :stirthepot:

:wtf2:

Maybe. That's why we will dyno with every part tuned and untuned. I'm untuned now with LTH, CBE, custom cai and the data log looks perfect. Its a little rich so actually more air flow could only help. We shall see whats needed.

that just seems weird since most of the time people are running very lean after exhaust and intakes are added. idk i'm not a tuner hence why i let someone else do it for me lol

any time frame on completion and dyno runs?

its nice to see something new trying to be done for the platform since no one really has messed with the lower mani or TB's. i mean GTM has that GT-R conversion kit for like 1500 :shakes head: and i think i may have seen one other place with TB uprgrades but cant remember where it was or cost.

found it lol oh google you rascal you.

Mines Motor Sports

Mine's has a TB upgrade for $1600 with core exchange.

Would z1's really matter? If I dyno again as is and put down 295/246 that I do, add our mani and it puts down say 10hp increase in the mid range where it counts and maybe a few up top so the peaks read 299/250, does another manifold need to be even mentioned if our mani shows goods gains and is half the cost or even less with better porting done?

The vender thing I'll have to talk with the owner on. I might just say, here's their website. Call or go there or mail your stuff in to get done. Wouldn't be any different than saying Discount Tire did a great alignment for me, go see them.

This ECU tends to work contrary to what you would expect. Don't be surprised if it gets richer as airflow increases.

If you get too far outside the expected envelope, in either direction, the car will just start dumping fuel, without throwing any codes or anything.

Example, put a 2.75" intake on the car. Does it go super lean and throw a code/go into limp mode?

Nope, soldiers right along, pegged at 10.5:1 in open loop, sits right in the expected range in closed loop. Clearly uses the MAFs for open loop only, relies almost exclusively on the O2 sensors for closed.


All this is to say, once you do your intake mods, if the car is flowing too much more than the ecu expects, even if it is tracking right on the MAF table, it's probably gonna start dumping fuel until you tune it, so don't expect a lot of gains beyond what you already have when adding parts.

Just my personal experiences and those of close acquaintances, I'm sure there are 10 experts on this site that will disagree. :tup:

There's a shop I linked in another thread that will do it for $200 if you mail in your TBs.

Only matters if you say "It is better than Z1's manifold" which you suggested it might be in a previous post, that's all.

I dynoed with cai and CBE then the LTH. You can see the sniffer tail pipe in the pic. The sniffer though is about 0.5 higher/leaner than actual though since that's read at the stock wideband. So I could use some leaning out still and some more timing.

I still need TB's so my cars not down. Anyone have some? :)

not a bad looking graph.

sadly the graph i got from my tuner didnt include my AFR on the bottom :shakes head:

i mean i didnt ask for it but every time i see one its on there hence why i just assumed it would be on mine. i got the graph pic saved on here if needed. its decent for just intakes and exhaust.

yea people are reallllllly touchy if a vendor/sponsors name pops up in a possible negative light. different wording and you should be ok.

Lol wow! IPS can setup the TB's on a CNC but that will mean new butterfly's. We will have to figure out the cost vs increase in power vs what just knife edging the stock TB with PnP will do.

This guy quoted me $200 with a 1 week turnaround (including shipping both ways).

Maxbore.com throttle body boring service and repair


I'm gonna do it, just haven't gotten around to it.

Gotcha. Well all i want to say is their porting is rough because they said really smoothing it did nothing power wise but cost went up. I think we can port smooth so it looks quality and price is lower. Power wise I bet they are even. I mean let's be real, we are only removing a mm or two from the part. One company can't out do another on that point.

i mean these are always a sexy little option lol

More Engine Development – 414whp with Kels *Video* : OnPoint Dyno

There may be a knowledge issue, but that can be gotten around with enough trial and error.

I suspect that Z1 probably ruined a fair number of these plenums before they found the results they wanted. Your guy gets one shot at it, if it works it works, if not it doesn't.

Like I said, I hope it works, can't wait to see results.

Yeah if you can go to HR heads, get big cams, hella expensive ITBs etc.

Good stuff..
