Heres the Beta part list and pricing for the G35 intake manifold swap!
Heres the Beta part list and pricing for the G35 intake manifold swap!
I recieved the following information from the good man John at infinitiparts.com today. The price is $821.86, rahter expensive. There is a decent possibility our lower intake manifold will work with this(part #'s don't match though). If this is true the price will be much more affordable. I am probably going to order all of this stuff minus the lower intake manifold tomarrow for $538.
BTW, they give 20% off all infiniti parts. Below is a copy paste of the very informative email I received from John.
Let me know what you guys think!

Pricing is as follows for the items requested;
Item Retail Your Cost
Lower Manifold $354.30 $283.44
Center Manifold $268.40 $214.72
Upper Manifold $268.40 $214.72
Manifold Cover* $109.60 $87.68
*The illustration makes this look like a gasket, but it is not the plastic cover for the G35 engine cover.
Lower Intake
Gaskets (each) $19.68 $15.74
Throttle Gasket $2.66 $2.13
Upper Manifold
Gasket $2.56 $2.05

Ethan, is that really worth it. What makes you think that will give you the power you are looking for. The G35's are dyno-ing at about what a 2K2 6 speed is..Isnt this true ?? What do you think ?

I think you've got too much money. Give me some
Seriously, it seems like you're throwing down $1000 here and a $1000 there, monthly. Wasn't this Maxima suppose to remain stock because you were tired of dealing with problems due to mods in the 95 SE and SC I30 
My apologies about the G35 intake manifold. It appears that you were entirely correct in saying the G35 does not have a VI mechanism. Goodluck with the manifold.
I assume you're doing the manifold swap because you're a bit worried that the VI 4th gens will surpass the 2k2s? j/k

I should try to save some money one of these days, as soon as I make it I spend it. This is my last mod I swear 
All I want to do is beat my frineds modded up the kuzoo Mustang.BTW My trap speeds will own all NA maximas

My last invoice was over 5K from Steeda ! . I guess Im well on my way again !
I just found another G35 dyno graph. The stock auto G35 put down 210 RWHP and 232 RWTQ. This dyno is making me a little iffy on the swap.. hmm.. The 6spd will probably put down 220ish HP and 240is TQ. This is still quite a bit better then a 6spd maxima.

Sure. I dont want to take any potential glory away from you if you are the first with a manifold swap, but it you are awaiting a test pig......I'm here. I do have some questions.....
1) On a scale of 1-10 (1 being frankencar install, 10 being engine rebuild) how would you *potentially* rate this modification?
2) We had a discussion of intake tracts yesterday....what sort of intake would I need for this? Could I use an Injen CAI?
3) How would this affect the ECU which I assume is programed to run the variable intake system, since this G35 manifold wont have it?

1. I would rate it a 3. I dont think it will be one of those mods that will blow you out of the water.
2. I would have a custom one Fab'ed ! To make sure everything sits where it should.
3. Thats the big IFFY, that I have. Can the ECU do this ? I dont think so ! But thats just my .02 !
This swap is not as simple as it sounds. But we need a guinea pig, so step forward young man !

2) The Injen intake will not work becasue the postion of the throttle body will be altered and there for the intakes tubing will no longer fit. A franken intake would be your best bet.
3) Good question. The ECU may adn probabaly will trigger a check engine light indicating there is a problem with the VI sensor, this should however should have no effect on the drivability of the car.
If you want to go ahead and do this first I want you to realise there is a decent possibility it will not work. If it does not work you may find your self with $500 dollars worth of useless G35 manifold pieces. You could check the return policy of the parts vendor you order this stuff from. There may be a restocking fee or even worse a no return pollicy.
Let me know..

I think I'll just play chicken (for now) and let you venture into no mans land and be the first to try this. When are you looking into doing it and is there anything I could do to help (short of doing it on my car)....donation perhaps to speed things up??????
I dont know guys. Im thinking JWT Cams, and other soon to come MODS will be a safer bet. We just need to hold our horses. I had a Ricer boy in my neighborhood look at my car, and say, " You Maxima guys are coming up huh ..?"....
..Yeah. Coming up your 9 Inch tailpipe's **** !

If you don't know a lot about installing things on a car this could get you in trouble. I will order the parts tomarrow probably. I have my Stillen Y-pipe project coming up in a few days so when that is done and dynoed I will begin this project. ETA 2 weeks with a dyno and write up. Thanks for offering your help dude, I appreciate it. I am a well known test pig though so I should be all right on my own. All I want in return is MOTM for a change, haha.

Well Kloogy, the sad truth is that we are the keepers of a dying platform (to the aftermarkets eyes at least). Granted, our engines our in practically evey interesting Nissan vehicle, but I just dont see JWT, or other trusted names offering us alot of help. JWT didn't make cams or chips for the VQ30DE-K at all. Who has a Y-pipe for a 2002 yet.......the cars only been available for over a year now.

Well, if your Stillen Y-pipe project is a success, let me know, I'm sure I'll jump on that since its fairly low risk.

Doesn't the G35 have a straightened air snorkel running from the TB to the air filter box? And I believe I read an org member saying he saw a G35 on the rack and that it also has a less restrictive Y-pipe. So my question is, why do you expect the upper manifold to make up the power difference between the Max? Not trying to discourage you or anything, just curious.

I found out the G's dyno I just quoted had a few spikes in it becuase of the traction control system
I hait to say it but this project is going to go on the back burner now, I just don't see big enough gains in it for the money it will cost me. The info is here if anyone wants to give it a shot..BTW in a few months we should be able to pick up these parts from a junk yard for about 1/2 the cost.
Thats a sound reply Ethan. Look at the cost to return in un-confirmed gains ratio... I would back away from this. If someone will do it first. Im willing to stand back and observe. But im not burning my $$ on this. I dont seee the facts to bak up the cost ! I think Ethan doesnt either !

I was just thinking that a VI manifold uses shorter runners for top end power. So any factory-built one piece manifold is probably going to be engineered to be a compromise between low end torque, and top end horsepower. Especially if its going in a production 4-dr sedan sold to the general public. Whereas the VI manifold can get around this compromise and do it very well. If anything it would be nice to take apart our manifolds and see if there is any irregularities or casting flash that could be extrude honed for power gains.

PS- Extrude honing is $400 for a 4cyl manifold, so...
PSS- is the 350Z manifold just like the G35's?

Theoretically the bigger the motor, the more hp you stand to gain from extrude honing (as with any modification). This mod is completely dependent on how smooth and aerodynamic the inside of your manifold is. I read an article in Muscle Mustangs and Fast Fords where a '99 Cobra owner took his stock manifold off and found it was not precisley matched to his lower manifold and that is had alot of burrs and flash on the inside. They ported and matched upper and lower and got a peak gain of 32 hp! But that is Ford and this is Nissan. It all depends on how good of a job Nissan did in casting our manifolds which can vary to some degree from car to car as well.

This may be well worth investigating since I remember reading on the Prelude board that guys could get around 10whp with this. Granted that was a 2.2L engine, so hopefully our 3.5L engines would be alot more. Do you have to send it off somewhere to have it done and how long would this take?

Yes you have to send it off. I'm not real sure how long it takes. www.extrudehone.com
Another advantage of extrude honing as opposed to hand porting, is that areas of the manifold that the die grinder cannot reach are polished and smoothed out by the extrude process. They developed a special compound that will flow with the surface of the metal but will also file away and rough spots or grit. From the primary runner tunnels to the smallest nook and cranny, everything gets smoothed and polished as well as sharp edges get slightly rounded.

People have been Extrude Honing the VQ30s manifolds for years. The truth is that there are no real gains from this. Nissan did a great job of keeping falshing down to a minimum. I doubt the VQ35 would be any different in terms of quality. If you do get the manifold honed, I've been told to expect about a month wait.
