That's almost like the one going in my car.

i have a question, if there is a difference between the C5 and the Z06 then why does vararram, haltech, blackwing, ect. have the same part number for the two?

 

What, no little flags? thumbs down

 

Differences are mostly internal, from the windshield being lighter to better springs/shocks to the MAF, heads, cam, intake (of course newer ls1 have the LS6 manifold) and even the block (some LS1 have an LS6 block)! See Roberts post on the full list.
As far as the flags go, they are there to know when to charge the vette tax. Makes things easier for the dealers to know when to adjust pricing...

 

There's your lil flags . Of course the ZO6 Nitrous Control Panel is aluminum and is lighter and faster than the plastic one...which I find odd because it was measured on a regular C-5.

Now that's sweet!
Maybe it will come in titanium next year!

 

algws6, the CAI are prob the same cause the mounting diameter is the same. Kinda like all the other interchangable parts, however, the Z06 did come with it's own air box that flows more than the c5, part of the maf/throttle body intake upgrade for more HP. Meaning, external mounting does not mean internal dia is not 80mm compared to 75mm.

Airwolf, don't you just hate the vette tax.

Beer, that's some funny chit. I can't use a panel that was fit to a C5.

White, yes I forgot the Titanium cat back on the Z06 for weight savings and power, and oh it sounds so sweet. I always get asked, what headers you running, none, hehehe.

robert, the intakes between newer C5s and Z06s have the same part number and i know first hand that the TBs are also the same. yes the airboxes are different and the only differnce between the mafs is the screen. this is why all the air intakes/bridges share the same number. i hope i don't come across the wrong way but i just want to sort out the facts.

 

So, your saying that the late model C5s also, use the 80mm maf and throttle body? I know they used the ls6 intake. I know the Z06 much better than the C5, so I am not saying your wrong, but do know for a fact that the Z06 has the 80mm set-up. I'll look it up in my vette service manual, when i get a chance, as the other vendors that may know, seem to want to make it like it's some kind of a secret? When I figure it out, I'll share it with the world. Thanks
Robert

 

yup, i am saying intakes, TBs, and mafs (with the exceptions of the screens) are the same. call your local dealerships and find out. this is why when people send thier TBs out to vendors for port and polish the core does not matter on vettes.

 

Al,
You are correct. You can also take calipers and see for your self since you havce an 04 ZO6 LOL. The internet is not always the best place for all the facts.
Dave

 

However, owning a C5 and a Z06 can be more benifical than you think. I have mine pulled out and on my bench. Calipers are at hand. I will have the measurements and will post all info for the entire world to consume. I am not afraid to share, and will have all the facts for everyone on my next post in this thread. I am checking part numbers also and verifiing that the above internet facts are infact facts, as Dave so inclined us to doubt. Why someone would hold back supposed knowledge is behond me, and not my style.

we are talking about plate setups right? There are only two openings for the intakes for LS1s (other than the TPIS modded one, and maybe the NX intake) that I know of. The ls1/ls6 small three bolt ~75 mm. And the 90MM 4 bolt on the LS2/LS7.

The plates only need to be one or the other AFAIK. I could be wrong...but thats how I always looked at it.

 

Al as far as bolting up and interchanging, that's really not what I am looking for, I realize this. what I am trying to figure out is where the specs of 80mm for the Z06 and 75mm for the ls1 are measured at, and if the they are one in the same for late model F-bodys once they went to ls6 intake. Did they move to the Z06 maf and throotle body at this manifold change, or stay with ls1 stuff? I hope I made some sense there, cause the noriginal question was basically a dedicated Z06 kit. i wonder if it really dedicated or just works or both? Does not the ls1 and ls6 flow different numbers? I don't have all the answers and am not afraid to ask and find out.
Robert

 

LS1 and LS6 what flow different #s? Intake? Intake opening? MAF? TB?

AFAIK the LS2 TB and intake opening is 90mm. I am not sure what the LS2 MAF is.

The LS1/LS6 stuff if I remember right was like 75 or 77 mm. All the TBs and intake openings are that same dimension AFAIK. Including truck stuff. 6.0,5.3, and 4.8.

The regular LS1 MAF is smaller than the z06/truck MAF. I have no clue what those dimensions are. I think it was ~75 for the LS1 and 85mm for the Z06 and 6.0 truck. That may be where you are getting the different measurement.

But for a plate kit to be dedicated for a Z06...hmmm. Not sure how you would do that. Maybe give the plate for that LS1/LS6 intake style and include a TPS setup. Something like that.

 

Here's what I found so far,
ls1's went to the ls6 intake in '01, however, I find no reference to using the larger ls6 MAF and Throttle Body on the later f-body.
Furthermore,
ls1 maf = 75mm
ls6 maf = 80mm
lq4/lq9 maf = 80mm

ls1 throttle body = 75mm
ls6 throttle body = 80mm
lq4/lq9 throttle body = 80mm

So, I at least see different part numbers between the 80mm stuff and the 75 mm stuff. Also, the Z06 MAF after '01 came screenless, so there is no way it has the same part number as the late f-body (even if they use the 80mm stuff) unless the f-body comes this way. Anyon have anymore insight?

Now it sounds like the plates and maf kits will bolt up, at least so far, but now the question is sizing on maf and throttle body.
Robert

 

LS6 throttle body is 80mm? Are you measuring the blade? diameter?
I pretty sure the LS1 and LS6 intake openings are the same.

 

Well, so far it seems the ls6 throttle body is 92mm on the in end, and 75mm on the out end. I am not currently in possesion of my inside mics, but the blade is smaller than 75mm. It seems there is the "Venturi Effect" built into the TB and this may be where the speced 80mm size comes from. The intake opening on the ls6 intake is 75mm, so again this is where the venturi effect comes into play, concerning the 80mm tb. This also indicates that the 75mm tb and maf would also work fine on the ls6 intake.

So what the answer. who is correct and who is wrong. You stated in an earlier post that the gm dealer I check with was wrong. Hmmm just like I have mentioned before the MAF fits, 80-85-90 units it just depends on where you measure it at. Funny thing is it really does not make a difference, if it bolts up and the holes are the same your good.

On the GM dealer, you said he stated the mafs were the same, they are not, different part number and different tune to go with. The '01 had the screen, the '02 did not, they may be phisicaly the same, but diff part numbers, that was my piont on that. dealers often do not know as much as the end user.

Who was right and who was wrong, I am not sure that any of this was about that. More so, just getting the correct info, and no one wanted to be specific, so let the reader decide. This is where the bs comes into play sometimes, certain vendors (if the hat fits wear it) do not want to give straight answers, so then those that don't know for sure have to ask. So which is worse, the asker, or the non answer'er.

Seems now we are just clarifing the different mafs/TB used on the diff cars, for info/tech sake.

In conclusion, it looks like ND, NX and NO have a kit other than a nozzle set-up to fit the Z06. Now whether these are dedicated kits, yes I suppose if that's what we want to call them, but, do fit many applications. So a dedicated Z06 kit?
