They've been shown to gain or loose power depending on the car for a while really.

 

They never seem to post any numbers better then a block off plate and power rod removed...

 

Ive seen this too and its what I was referring to when I referenced the vq30 timing equipment instead of the vq35 vtc's. IIRC, the car that was tested did NOT have vtc's which means the cam timing was really just not even close to what this manifold wants

typically gain power with an SSIM over a BOP over 6500 or so. In my experience, the BOP is better is you have stock cam timing, but if you go with z cam timing the SSIM is better. When I had my cam timing adjusted, I picked up 20wtq over a range of something like 3500-5500 with no other real changes

 

for those still following, I just bought a powerlab 3/8" plenum spacer and I will be dropping the engine/trans about 1" to accomodate the extra height. Ill document both here when they happen

 

thanks gemner.. im following,... how do you plan on dropping it?,.. also.. do you already have ES MM ?

 

yeah I have ES motor mounts. Ill be dropping it by drilling 1 new hole in the passenger side mount and putting spacers and longer bolts in the other three locations. Ill be sure to grab some pics when its done

 

I'd worry about the axles...especially if you are lowered

 

should be fine. I got the idea from the guys that won the NASA nationals in their vq35 B15. If it doesnt blow up their axles I should be more than fine

Edit: plus I already have raxles on both sides for an added safety factor

 

Hmmz your right man. I just took a look at one. Kinda makes me wanna put the OEM manifold back on since I never rev past 5k anymore really.

 

HERETIC

 

well, I dont have much to report here. I did hit the track and ran a 13.7 (previous PB 13.5) and quickly found out that this clutch is toast. My 13.7 run was mostly ok on the clutch, a little problem at the start and a little slip into 4th, but on another run I was not prepared for the launch and my 2-step didnt engage, so i ended up launching at like 6k. Let the clutch out, foot off the clutch gas to the floor and I stayed pegged at 6k for quite a distance before the clutch grabbed at like 5k. That was after even lifting off the gas a little, feathering it but it kept slipping. lol. bellhousing was so hot I couldnt really touch it. I know somebody is going to come in here and say something about losing time, but it must be understood that I sold my VAFC2 since I last ran and my car runs VERY VERY rich for some reason, im talking low 11's AFR. I went thinking if I ran 13.8 or faster it would be a manifold success, since last time I tuned my AFR, the untuned run was sub-200whp and the final tuned run was 230+whp. I figure even with just a basic AFR tune and operable clutch that I would have pulled a 13.3 or so, its that bad. Anyway, when I get the clutch replaced and get some tuning done ill update this. Ill also add pics tomorrow of the engine drop, powerlab spacer, and my version of the MREV2

PS: another member (ulyses) on here rode in my car and when he got out he commented on how smelly it was (gas) and an exhaust tip swipe showed how much more rich im running than he is (TS tuned, so hes probably no higher than 13.0:1)

 

First things first, my version of the MREV2. Now that I see it a little better, it needs the top cut down a little more along with the others


And here you can see the polishing I did. I didnt go too crazy but I hit the problem areas pretty well


Powerlab spacer installed. Some of you experts can probably spot how much lower the engine is by looking at this picture. Its quite a drastic change if you see it in person. Really surprising how much only 1" or less of drop actually looks like


Heres some engine drop shots. These are the spacers i used on the crossmember and the transmission mount (this is the front of the crossmember). I just bought longer bolts (1"), the spacers, and some washers and unbolted, spaced, torqued. Pretty simple.


Last but not least, the passenger side engine mount. I drilled a new hole and put the bolt through at the new hole. Again, pretty easy. You can see where the old bolt hole is compared with the new one

 

wow.. that sure is something... thanks for the pics,.. did you 'try' it without dropping first to see how close it would be? or was it that close without the spacer?



also..how are you tuned? wideband and S/Vafc2?

 

It would have rubbed by just a little under 3/8" if I hadn't dropped it. It was pretty dang close. I'm currently not tuned at all. I'll be utec tuned next time it's tuned

 

we dropped the motor in the Joe's car (b15 w/ a VQ35) about 1.75 inches at first, lol. The oil pan was kinda low, we ended up raising it up about 3/4 of an inch. It's nice and low.

Curious to see the dyno numbers because we have more than enough room to fit an 350Z intake....

good work on dropping the motor.

 

Cool thread, I'm going to keep following it!

 

im curious too. cant wait to get some sort of tune and go for it. might be a bit

thanks for the idea. on a side note, the axles survived a 1100 mile drive, so looks like the angle is fine to me

 

drive line angles is a myth... anytime you lower a car the drive line angles change, so whats the difference if you drop the motor?

It should have really helped you CoG. Does the car keep traction better in straight line acceleration?

 

hard to say really. When I was running at 253 whp i didnt have much of a problem in any gear keeping traction. Now that im untuned i bet im around 240 or so, so for obvious reasons my traction is a little better. oh and my clutch is slipping bad, so info about hard shifts is out the window. lol, got some stuff to work on over here

 

would there be any kind of gain without VCT and a completely diferent timing map(vq30)

 

i was going to say the same... VQmonster did it down here and had not much difference if any... good if he did though... it was the same as the SSIM down here

 

any updates on this? Great job by the way.

 

Well I've been looking around for intake manifold upgrades and didn't exactly find what I was looking for. I've noticed on the new maxima they switched over to a composite intake plenum....So I'm very interested in seeing if it will bolt on to my 02 and what kind of results will come of it? I'm thinking it should produce more power with the smoother air flow and reduced heat transfer. Am I a little late in mentioning this or am I the first?

 

You're late. It doesnt fit. The heads are different.

 

I was looking into doing this on my I35 but I already ordere my spacers for my stock manifold. oh well

 

nice thread, any updates

I'm sorry your answer doesn't convince me very much. It's fine if the heads are different because I'm interested in swapping the plenum, not the lower intake manifold. As long as the ports from my lower intake match the composite plenum ports I should be set......well, I would also have to look at the bolt pattern for the TB.

 

That doesnt fit either. I've already tried it personally.

 

Told.



Interesting info here tho.

 

well, you convinced me for a little while, but then I realized you have a VQ30DE. I don't, my 3.5 has a completely different plenum and I'm assuming the lower manifold is a lot different also, because the bolt pattern is not even close.

 

He is talking about a 3.5.... Promise ya if this was a bolton affair, I'd have already done it.

 

I have a VQ30DE-K in my car and a VQ35DE sitting in a corner in my garage prepped and ready to drop into any 95-01 maxima. I've also helped install the VQ35 your refering to with the black plastic intake manifold into a 4th gen. One of the first in the world to do it. And yes I tried swapping manifolds.

But I dont know anything. Go ahead and waste your money. Buy one, try it, cry that it doesnt work, start a new thread on the .org stating that it doesnt work. Then listen to everyone say "you should have searched because we already know". This is already common knowlege that it doesnt work.

Where have you been?

 

 

You know what; I'm not trying to step on your toes. I just wanna make sure we're on the same page here. I'm a little skeptical when it comes to what is said in the forums, because most of it is somebody just giving there two cents or guys who know it all, but really don't know anything. And I really don't have the patience to shift through that kind of stuff. I like solid, informative answers with proof to back it up. Also I did do my searching, I would'nt even be having this conversation with you if it was this common on the forums.

 

desto, can you use a different txt color, older headers like myself kept the throwback maxima.org theme where the background is white and i cans see a word that you wrote.. just be regular and keep it black bro

 

the dark style has been around since before you joined...

details?

 

hahaha

 

Slow...

Without anything to control cam timing and the dual VIAS assembles in the IM, etc.. its a waste of time. It loves nitrous though, but what VQ doesnt?
