Yes.

 

he has a full swap 3.5...with an a33b ecu

 

I'm assuming you mean a 3.5 swapped into a 4th gen, likely without the A33B ECU.

So with all those mods AND the fact that you don't have AC and power steering, you think it's easy as pie to whip up another 45 WHP from cams?

 

I want those when they come out. **** every other mod...just get cams!

 

I've known that since before the thread was started, but thanks for the reminder.


My post was to whoever was asking about current TS ECU offerings.

 

Actually, it's in a B14 and it's running an AEM. I've whipped up 50 hp on a set of JWT cams, springs and retainers before, and that's on a 4 cylinder. I'm pretty used to N/A 4 cylinders running 180-200whp on just 2 Litres with almost no internal work. My DE was running 170 with just cams and very basic bolt-ons.

Here's a Video of my IHE VQ35 run:

I'll tell you what, it would probably be easier to drop the weight then to try and reach 300 whp. Now 275 whp would be a very respectable amount and that should be easily attendable enough that you don't break the bank. And then go turbo for the fun of it.

 

that's a first.. 50 hp with just adding cams, is that what i can get..
so... if headers, zim and 3" maf get me in proximity of 250 whp, then adding
cams will kick it up to what... 300? just asking

 

In order to become faster, yes, but for ‘bragging rights’ (I reached 300 hp whether it be whp or bhp) you will need everything and then more that is stated in this thread.

 

Prove it. I don't believe that, not on anything DOHC, and especially not on a 4 cylinder.

You have to keep in mind that VQ's breath fairly decently by the nature of their factory designs. Now, that isn't to say they breath really well, just hard enough to improve upon in really large amounts (i.e. the 45 whp from cams). This is because it is a fairly modern, DOHC V6 from Japan (and by "from Japan" I mean it traditionally prefers revs). You can argue that fact all you want, and although the VQ doesn't set any records it certainly isn't an easy NA platform to get big power out of.

 

can start with a better designed intake, the intake in that video looking like it was sucking power by the ton

 

What about head work and oversizing your valves by 1mm would that be a benefit?

 

Oversize valves are unnecessary. If you guy are serious about the 300 WHP thing, please look at my post where I listed to the most important items. This is how those who have done this before have gotten there, or close. It's not that complicated. It's not cheap or easy though.

 

Check out the dyno numbers on SR20forums. The lowest is about 30whp increase.

I'll assume the 3.5 breathes better in stock form, so you may be right.

Either way, I'm quite determined to hit 300whp and trust me, I don't plan to open up the bottom end.

 

I'll be happy if I for some miracle break 240 whp with my vq30dek NA but thats a pretty big miracle

 

well, im glad to hear that youre being realistic

 

Then I guess I'm in the 3.0L part of the forum.

 

what?

 

Well, as an SR guy, I'm having a little trouble imagining that 3.5L owners are having this much trouble hitting 300 without disassembling the bottom end. Based on our judgement, 100whp/Litre N/A is not unfathomable. Most people on the SR-forum are reaching 90-95hp/litre without any bottom end work, some are actually hitting that 100whp/L mark without messing with the pistons.

This might sound a little conceded, but I'm making 255 to the wheels. I'm taking your word for it that I prolly won't see any more than 30 out of a set of cams, however, I'd imagine if you add in a tubular manifold and thermal spacers, I'd be there.

 

History doesn't lie. You'd be the first......

 

Well then, wish me luck.

 

Adam at Z1 is a total douche and an Idiot. I've told him that a couple of times. What your VQ needs is some headwork, and a good set of cams. You'll also want to look into a good tuning device to work with the VVT, or even full stanalone (which will net more power)

There are a few people on my350Z with around 300whp with just boltons and a tune.

 

Don't 350Z's start off with more power?

 

They have better heads and different tuning.

 

Different UIM too.

 

what you dont seem to understand is that it is harder to make more hp/liter with a larger engine. how often do you see 570HP 5.7 sbc's running around on stock internals? or any version of NA and still at 5.7l?

yes, but its 99.9% tune. the z is damn near identical to the maxima engine, only difference is the uim (no better than SSIM) and exhaust. then the tune comes and they get a better a/f ratio and more timing...hence more power

 

no...everything in the engine besides the uim is the same...cams, heads, pistons, crank, valves...

 

No. On what year VQ35? if they are 4th generation maybe...But the ecu tuning is different, that much I know.

and SBC's are 2 valve Pushrod motors. Not to good for hp/liter.

 

Yes. Your correct. I did see somewhere on here a back to back comparison of different IM's and iirc the SSIM made the most power with the setup it was tested with.

 

As was already mentioned, this is incorrect.

 

all of them besides the revup and before the hr came out (02-06)

much? i said that in my other post. that is the real, important difference. more timing and better a/f

 

^^ The VVT maps are different as well.

 

2002 max's and Pathfinders VQ35DE do INFACT have different heads, and they flow like ****.

 

I have compared part numbers and maxima/altima heads = non-revup 350Z heads. The only reason revup heads have a different part number is because of the stiffer valve springs and revised retainers.

 

Revups have VVT on both intake and Exhaust Sides of the head, better rod bolts, and a better oil pump as well. The first VQ35's heads do flow like crap. I'll see if I can dig it up for you.

If you don't think so, how can a car with less drivetrain loss, and same mods put out less power?

 

yeah i know, but that doesnt really affect the peak numbers he's talking about.

 

youre going to have one hell of a time digging/making that up. maybe you mean early pathfinder heads, which =/ maxima, altima, murano, fx35, g35, 350z, quest heads

 

As far as some I am concerned the rev up oil pump isn't better, esspecially if your going the get max HP out of a VQ, which is the title of this thread.

To get as much hp out of a NA VQ you will need revs, and dandymax proved that the pump couldn't rev to 8k.

 

I'm not going to argue some points, but Someone tore down a pathfinder VQ and compared it to the 350Z vq, and commented on how everything from the cams, to the heads were ****.

The Revup does infact have VVT on both intake and Exhaust side. I'm 110% sure of that,

 

chances are it wasnt the pumps fault. the case wasnt designed to run with a 3.0l, its designed to match the vibrations and whatnot of the hr. the pump is good to a stock revlimit of 7500, which means its most likely good to 8k+ in the same engine
