Where did you get yours? How much? How do you like em? Worth it? Anything else?

Thanks

There has only been one instance with cams on a 4th gen.

JWT- $1100 or a GD for ~975.
He dynod ~212 w/o JWT and stock IM.
Depends on what you think is worth it, typically 13-15whp ..

There are a few other options such as VQ35 cams, check this forum there's a thread on the subject a few pages back.

they're not a big thing with 5 or 5g owners, b/c most of us can get some decent gains w/o them, and like to keep the low end we do have right now.

There are a couple of folks with them in their 3.5's, but you stated 99 which has a 3.0 from the factory.

i have jwt 3.0 cams in my 3.5 (4th gen) I think they suck. I have used 3.5 cams in a customers car and it felt alot smoother and still pulled too 6500 real well.

Yeah f*ck the cams. Intake manifolds are a much better place to look for power.

Iron Lung is still running around with his JWT Cam setup and stock manifold. Last I spoke to him he pulled off a 14.1 @ 99 NA and 13.2 @ 111 on 100 shot spraying 3rd and 4th only.

He was the one with 212whp I was quoting in my first post ... , I think I still have the vid when he ran w/open headers. I'm sure with some better launches & weight reduction he could be in the 13's easy.

so, what, they arent really worth doing until getting the last few ounces of HP out of your motor. Money aside, would you rather go boost >first<?

I want to get JWT cams for my DE-K, but I'm affraid the low end power will go down ALOT and I will not gain much on top end. I need some more info on these cams, I am going to be tearing my motor apart anyways soon to do my timing chain tensioners.

JWT VQ30 cams are crap...

With the JWT spacers you can run any one of the several aftermarket cams out there for the VQ35 like JWT, Nismo S/R, Tomei, HKS(forsale yet?), etc..

Cams typically shift the powerband upward and are a must for NA ultimate performance.

DEK/MEVI+JWT or TS raised limiter+Tomei cams would be a beast.

I wish more people would try cams besides JWTs one-cam-fits-all NA/FI/N20 VQ30 cams.

BlackBIRDVQ

iTrader: (15)

Problem is JWT doesn't wanna sell those spacers no more I thought ? Tomei cams are not a problem for me. I don't wanna be inside the motor again as taking the VIAS off is a pain in the azz. I'm going with TS ECU with raised redline, I would like to hit around 250WHP if possible with all mods completed.

They won't sell them to individuals but they will to businesses, which is where Tilley's shop comes into play.

Cattman can order them also....not sure how much though.

I think Larrio might be getting Tomei's 264s, if so, we'll FINALLY have a dyno. It would be interesting on his car, since he has a DEK and 7100rpm limiter.

250whp on a street VQ30 is pushing it, don't you think? 250whp is hard for a VQ35, but a vq30? GL.

BlackBIRDVQ

iTrader: (15)

I don't think 250WHP on a Street VQ30 is pushing it, that is about 300crank HP with 3L of displacement, a street driven emission friendly SR20DE with NA mods will hit 200crank HP with simple bolt ons, and there have been cases of 250WHP mild head work and I stress MILD SR20s. I got another Liter of displacement to play with, 250WHP is eassy to attain on a VQ30, I just don't wanna spend 3K dollars on head work with DPR to go past 250WHP - just yet. Trust me I have thought bout just sending a set of spare DE-K heads to DPR for Stage V competition head job, since doing cams is like 3/4 of the way to doing head repleacement. Talking with DPR they noted that VQ30 heads have ALOT to be gained from and he can almost guarantee another 30WHP if not more from their head work. I showed them my dyno sheets and he seems to think over 300 crank HP is not a problem.

I'ma talk to Tiley and see if I can score some spacers from him and order up some Tomei 268s.

iTrader: (3)

Will you finally show a dyno?

iTrader: (4)

I dynoed 209 whp with just bolt-ons, no internal engine parts touched. If I would switch to the 00VI that is all the rage, I would pick up another 5whp (10 according to some), with cams and some mild head work, I would think 250whp would be no problem. Its just not worth the money.

JClaw

iTrader: (17)

I'd rather do all that work to a VQ35 and end up with greater results.

BlackBIRDVQ

iTrader: (15)

I have nothing against each motor, but I reather stick with my silky smooth and reliable 3.0L. Everyone is in love with the 3.5L for its power, but in real world 3.5L has TORQUE over 3.0L, there aint much HP over a DE-K when looking at the dyno sheets.

Larrio

iTrader: (10)

the 3.0 has much more potential in the long run than a 3.5 (IMO)

the shorter stroke, high revving engine is nice to have. The 3.5 has the edge in technology and displacement. There is a reason why ppl start switching over to 3.0's in the Z's at a certain point

ICE: check your PM, I have a update

NmexMAX

iTrader: (22)

People are dropping 3.0's in their 350Z's?

JClaw

iTrader: (17)

I'd like to see an N/A VQ30 put down 295whp without any internal work except cams. That is the current N/A reccord for a street, internally stock VQ35. Good luck getting there with a VQ30.

Seriously, VQ35 will eat a VQ30 alive same money invested. It's the same ******* thing with more displacement. It just likes to rev a little less. So what? We aren't driving Honduhs here. You don't NEED to rev the f*ck out of it to make power and find out that you're producing 2 pounds of torque at 9000 rpm.

Is that doable in a maxima though? That would include the full 350z wiring harness and ecu conversion, to take advantage of the cam timing and other electronics. Also, that includes long tube headers which can't be done on a maxima, intake manifold that won't fit uder the hood either. All that extra torque is hard to put down with fwd as well. The guys that have put a 3.5 in their maxima have unimpressive dyno numbers considering the money and work. You make it sound like its as easy as putting an intake on, just slap the engine in the car and voila, 295whp....its not that easy.

JClaw

iTrader: (17)

The reason 3.5 swap dynoes are "unimpressive" is that nobody has had their ignition timing advanced to anything resembling what 2k2s and 350z's run. Vq35 heads can handle it but the 95-99 ECUs will still continue to run the engine like a Vq30, and that means (relatively) sh*tty @ss timing. I hope to be able to get it done without rewiring anything other than the Odb1/Obd2 harness adapter.

Headers on a 350z don't give much gains for the $$ because the stock ones are already so good, I doubt our FWD aftermarket headers are much worse than what these guys get, since it doesn't take much other than headers to get a 2k2+ maxima to dyno the same as a stock 350z.

I never said 295whp was easy on a 350z, it's a RECORD.

You guys are comparing fully tuned VQ30's with all the bolt ons to 4th gens who just had 3.5s swapped in and say it's "unimpressive". Give us the time to breathe. Financially I'm not in the best of situations right now, so putting money on my car is dumb. When it gets better I will advance the f*ck out of the timing, tune it, dyno it, and show you it was worth it.

I have to strongly disagree with this. People can choose to swap in totally stock VQ35's with no other mods and call it a day. Take Nismo3114 for example. The entire swap cost him around 1000$ + his Y-pipe. Stock crappy exhaust manifolds and all.

Yet, he goes to the track, and first time, pulls a 14.06 at 100.7 mph. Considering the money invested, that is VERY good bang for the buck, over a second faster than stock. You make it sound like this swap is expensive. For the results it gives, IMO, it isn't. It's cheaper than the majority of Honda swaps. I'm sure you have more than a grand invested in your car.

How many 4th gens pull 14.0's@100 mph with a thousand invested N/A? Not many, not to mention the extra potential of the VQ35.

Guys since this thread is about CAMS, I was wondering how much Tomei cams go for? I googled around and found nothing about tomei cams for the vq35de :-(. Thanks

JClaw

iTrader: (17)

You will pay a little more than a grand for any of the cams (Tomei, Nismo/JWT). They aren't cheap.

I was on the 3.0 bandwagon to but i have a 3.5 in my car now and i must say . It is just as smooth as my 3.0 was ,revs just as high as my 3.0 does. weighs 35-40 lbs lighter in my case than the 3.0 does.

And to my amazment with the dek on the 3.5 the spot were i HAVE to let off the gas 7600+ ,its still pulling really hard. Harder than the 3.0 did up there.

I have made a promise to this engine i will keep it at or around 7500 tops because i dont want my oil pump to explode like my 3.0 's did. wish i put another in the 3.5


And for cams maybe down the road ill get the 272 nismos or a 268 but no jwt for me

A JWT or TS ecu would be just the thing to take care of that.

Aftermarket 3.0 ECU's are just approacing 3.5 stock timing or slightly more advanced. The timing that SR20 is running now is unattainable with the 3.0 ECU options we have. SMT-6 anyone??. BTW, how much does an SMT-6 go for anyway??

IceY2K1

iTrader: (3)

I've seen them for less then $250 on eBay.

Stephen Max

iTrader: (59)

Why would that be?

IceY2K1

iTrader: (3)

I wouldn't care to have JWT or TS's "one map fits all" approach for this type of application.

This is something you need to finely tuned on a load based dyno to eek out anywhere near maximum power, therefore the SMT6/SMT7 or another piggy that can control timing would be ideal.

jim goughary's SCCA 350z with a maxima lower IM
top secret 350z
nismo JGTC 350z



like i said, "at a certain point". For race use, most don't even bother with the vq35

Because TS 3.5 timing > TS/JWT 3.0 timing...

The 3.0 heads are the limitation. 3.5 heads have superior cooling due to the revised coolant passages and long-reach spark plugs and thus are more resistant to detonation. And like Icey said, a piggy-back computer like the SMT-6 is the only way these guys running the 3.5 off of the 3.0 ECU's will approach 250+ WHP (with stock 3.5 cams of course).

Stephen Max

iTrader: (59)

Can't you get TS to program your 3.0 ecu with 3.5 timing? JWT might give you one of their stupid arguments, but TS is a bit more cooperative, no?

IceY2K1

iTrader: (3)

Honestly, I don't think TS does much/if anything with timing.

I'd have JWT do a 100-octane program for timing and then fine tune the AFR with an AFC, if I had a 4th gen. ECU.

Nealoc187

iTrader: (23)

Most people that get really serious about their motor, be it NA or FI, go with a standalone (AEM EMS, MoTeC, F-con Vpro, etc), or at least a fully programmable piggyback a la Hondata, Zemulator, etc. Once people get to that point with VQs the current ceilings of HP for NA VQs will be a thing of the past. Proper engine management, along with proper mods to allow it to breathe as required to start raising the NA bar.

Granted this isn’t about cams but it should answer some of your SMT questions, also I don’t know if its worthy of its own thread or not. A Mod can make that decision...

Aftermarket 3.0 ECUs are weak in the timing advance, I’ve been able to exceed the timing done by JWT ECUs and not face any detonation problems in this cold air we have in Mass right now.

However the SMT-6 can't understand the cam sensor signal, it's to complex for the SMT-6. As such you end up only being able to push the crank sensor signal. When I push the timing advance too far it just throws 0101 codes left and right, which causes a loss of power. The 3.0 ECU has a timing tolerance that's RPM dependent and so far the upper tolerance limit isn't even close to detonation, but it sure as hell throws 0101 codes if you exceed it. So in order to really push the timing on the 3.0s were gonna have to advance both crank and cam signals. This in theory should not cause 0101 codes to appear and allows us to dial in the maximum useable timing advance for each specific RPM range. The only device capable of that is the SMT-7; however this has its share of problems as well.

Since the SMT-7 is designed to be a universal fit for more complex and modern ECUs, it's wasn't designed to be Maxima ECU specific. I’m currently working with Perfect Power on getting the '95~'99 cam sensor signal code programmed into the SMT-7, if I can make the deadline it should be on the next SMT-7 firmware upgrade. Provided they can make sense of the oscilloscope signals I send them.
This is one of the unique features of the SMT-7; you can upload new firmware so the module increases its memory of signals it can process.

And to keep this thread on track you can use the SMT-7 to gain back some of the mid range loses experienced with using aftermarket cams.

Edit: Also keep in mind Maximas are not the only car that has this problem with the SMT-6 , for example newer VWs suffer from the same problem. The SMT-7 was designed to advance crank and cam signals to allow for problem free timing advance.

Or we could convert to OBDI and use a 300zx ECU and run whatever the hell we want
