I've tried a number of exhaust setups on my Maxima. Before I got my Y-pipe, I had a RT Cat, 2.5" mandrel-bent piping and a Magnaflow muffler. After I got my Y-pipe, my exhaust was just too freaking loud. The first thing I did was install a Magnaflow resonator. That helped some, but the exhaust was still too loud and drooooooooooooned like hell. I finally sold the Magnaflow muffler and reinstalled my OEM muffler. That did the trick.
The difference in performance between the Magnaflow and the OEM muffler wasn't noticeable . . . at least not on my butt dyno. I'm sure I lost a couple of hp. But believe me, the tradeoff was worth it!

Besides that, we weren't supposed to get off on this tangent anyways. All because I called the oem muffler a gimmick? Just liek you I had the argument with Ethan about it not being one and in the end he won. There was a person who put a 5th gen muffler on a 4th gen car and got like 1 hp if that. I only called it a gimmick because they make it sound like it's such a great work of art but in the end it's just a very expensive oem muffler with some mechanical do dads inside.

If you're planning on installing a Y-pipe when they become available for the 2K2 Maxima, I'd strongly recommend that you do that BEFORE you make any other modifications to your exhaust system. Trust me on this one.

Re: Re: It has to be in the Intake manifold
I'd have to disagree http://forums.maxima.org/showthread....30DE+AND+cams. I know that the 95 VQ30DE cams have around 240* duration on the intake/exhaust. I'm sure that cams with simular specs to the SR20DE or ISKY/JWT stage I or II would make a big difference in topend power. VG30's see around 20-30whp with stage II cams + headwork and 10-20whp wiht stage I + headwork.

So what do you guys think about using the 2001 VI manifold in place of the 2002? I may be willing to try this if you guys think it will give me good gains. The way I see it is if the 2000 gained 32 HP over the 99 and then the 350 Z is gaining 22 HP over the 2002 max maybe the
2001 intake manifold is better then the 2002's? Nisan might have stuck a junky intake on our cars just so they could pump up the 350Z's statis.
BTW any chance the 350Z intake would fit a 2002? From looking at the picture it's hard for me to figure out how that motor is angled in terms of the intake
Just some thoughts from a HP addict

Now the 350z intake manifold may have some promise. We would have to assume it flows the same or better than the intakes we have. The only real problem I see with it is the throttle body placement.
I just found some interesting videos on Nissans Pathfinder page.

Nissan also changed the style of injectors on the VQ35 so they probably won't seat properly in the VQ30 plenum without some custom seals.

You'd have to check the upper intake manifold to lower IM gaskets for both engines. They might swap over, then again maybe not.

Re: Re: Re: Re: It has to be in the Intake manifold
Damn boy nissan went very conservative on the camshaft profile. Ignoring the lift and size of the valves my factory 87 VG30E has 20* more duration and more overlap. VE's run 248* with 9* overlap as well as the VG30DE's. That is probably why VQ's are the torque monster's they are. Cams would rock in a VQ, there would be a low speed torque loss but the gain after 4000rpm would be tremendous. Hmm JWT or custom cams + MEVI + 7000rpm rev limiter =

.I figure if we build a VQ35 with 12:1 static compression, a very short runner intake amnifold and install some cams with 280 to 292 duration with about .480" to .500" lift we could rock Hondas' world.

I think you'll find it very difficult to build a drone-free exhaust system around a Y-pipe and a straight-through muffler. But give it your best shot and let me know how you make out.

Isn't that hard eh? Do you realize that the entire front cover has to be removed in order to remove the cams?
Ruin the engine? If a custom IM is made to retain driveability I would say it's feasible.
And we know everyone wants a turbo kit. That would be easier and more productive but wouldn't prove our point about how good the VQ could be NA.

If you use 3350 lbs for the 350Z and 290 hp, the weight/hp works out to be 11.55 lbs/hp...with that much better power/weight ratio the car should be much under 5.4 secs 0-60 and 14.1 at 101 for the quarter mile, moreso considering the improved aerodynamics versus the E39 body.
Granted...the HP is very likely better than 255 but 290?? Nahh...I wont buy that for a minute...

Also, you must factor in transmission gearing and efficiency. Say what you will about bmw but their trannys are fantastic.
Who knows what the Z will really run? I can't imagine that a good driver who pushes the car won't easily get 13s stock.

you are correct; the larger displacement engine usually holds the power much longer and usually also has a FLAT powerband... therefor more useable power. Ever wonder why people are revving their engines up a slope in an inline-4 car?

Any ideas??

If this gearbox was made by the same company that made the RS5F50 (A) (V) (4th gen 5speed) then I expect it to eventually break. Lets hope the gears themselves hold out fine.
And yes Ethan, we couldn't have asked for a better street clutch than what Nissan has given us. Lets be thankfull they at least got that part right. And since they put such a strong clutch in these things, added alot more power and torque, we can assume this gearbox would have to be alot stronger than the previous ones. Now if they'd just start giving us kevlar syncros we would have a gem of a gearbox.

my uncle is thinking about opening a Nissan dealer here in Northern VA. hopefully it will go through and hopefully i will have access to all of the 350Z parts to test most of what was just talked about. who knows when that will happen though,

Y2K, we all have our opinions, drop the exhaust thing. Just do what makes you happy, but let everyone else do with their $$ as they want. I dont have a problem with people trying to save money, but cutting corners is so stupid, when you drive a 30 K car . I haven't seen too many Skylines with stock exhausts !

The only real problem I can see at the moment is that Nissan is still using crappie brass syncro rings in 2nd and 3rd gear. I suppose thats all most people need but I am not most people and my 3rd gear syncro is shot. I just flipped 7000 miles on the odometer. I have also noticed that my HLSD has malfunctioned once or twice.
If this gearbox was made by the same company that made the RS5F50 (A) (V) (4th gen 5speed) then I expect it to eventually break. Lets hope the gears themselves hold out fine.
And yes Ethan, we couldn't have asked for a better street clutch than what Nissan has given us. Lets be thankfull they at least got that part right. And since they put such a strong clutch in these things, added alot more power and torque, we can assume this gearbox would have to be alot stronger than the previous ones. Now if they'd just start giving us kevlar syncros we would have a gem of a gearbox.

Y2K, we all have our opinions, drop the exhaust thing. Just do what makes you happy, but let everyone else do with their $$ as they want. I dont have a problem with people trying to save money, but cutting corners is so stupid, when you drive a 30 K car . I haven't seen too many Skylines with stock exhausts !

Once again, my only interest is in presenting the facts. And I intend to keep doing precisely that. Those who can't stand the heat should stay out of the kitchen.

Fresh Alloy reports 290 hp out of VQ35

Each camshaft has it's own part number (left exhaust, left intake, right exhaust, right intake). The Maxima and the Z car use exactly the same cams.
It appears that they both use the same lower intake manifold but I didn't get part numbers on that. The Z's upper intake is in two pieces just like it appears to be in the pictures. A bottom and top piece but the dealer only had a price listing for the bottom part i think (about $268).
The Z does have different part numbers for it's fuel injectors. It lists a Bosch and a Unisia - Jecs part.
So if the Z does have the same cams, same valves and same heads that only leaves Intake, exhaust and some ECU mapping tweaks to make the extra power. I suppose we'll all learn alot more once someone finally gets a Z on a dyno and posts a graph.

Re: Fresh Alloy reports 290 hp out of VQ35
I can't see more than 5 or 10 hp coming from the intake/exhaust, expecially if the intake manifold is the same (i.e.: no extrude hone or anthing). The exhaust on the 2k2 is already quite good anyways. I think the engine is being choked in the ECU.
If this is true it may be worth our while to talk to someone like GIAC, en masse, to convince them it is worth their while to compare the Max ECU with the Z ECU and come up with a chip.
On a side note, I wonder if the VQ35 in the G35 Coupe is going to be making any more power?

Matt I was just wondering about the lower intake manifold, thats good news about it being the same part. Now I am trying to figure out where the 350Z's intake manifold would end up on a maxima. My guess is it would settle right next to or on top of the Front strut tower. Hmm.. maybe we could get it to work but I would need to know the measurments on it before trying. The 6ht gen maxima intake may however be a perfect fit. This is going to be fun

whooo hooo replying to this neverending post is interesting. as far as cams go, its not that hard. yes the front cover and all the major accessories have to come off, but its still fairly easy. The cams are right under the valve cover. I have cam locking tools so its even easier. i've done countless swaps when i worked at roush for the DOHC escape motors. honestly it sounds like the best idea to get a crappy car for driving to work, and then buy a 4'th gen and swap motors. I would put a VQ engine with some work in a 4'th gen. I love that pull all the way to redline. a set of good cams and a good ecu would easily give that vq motor at least 50+hp. but at that point you need a bigger fuel pump, possibly bigger injectors, and the MAF sensor to go with it. Heres A GREAT IDEA! See if the connections for the VQ3.5 fits the 3.0. See if it is bigger. I bet it is. A bigger MAF on the car will flow much more air, and im betting you would get at least 10 hp. just think if you could swap the ecu and the injectors!?!?!

From what I have taken apart and seen already it looks as if it would be easier to remove the entire engine to do a cam swap vs. doing the work inside the car. This engine is VERY easy to work on as long as you dont attempt to remove cams or cylinder heads. It does look as if it's fairly easy to remove though. The other problem with a cam swap is that currently there are none. And if we did get cams made we would have to get a new ECU prog to extend the crappie 6600 RPM limiter. This motor should have been built to make peak power at 7500 rpms.
As for the Z manifold just imagine looking at your intake manifold and turning it 90° clockwise. By the way, I have started on the 'project'.
