Well, I've been planning the swap for some time. I am about to buy all my parts this month. Before I proceed I would like your advice.

I'm looking to get as close to 300hp N/A as possible. Here's my parts list so far--none of it is bought... yet.

3.5 motor of course
EMU-A32 timing equipment
Alum Flywheel/Exedy stage 2
UDP
Header/Y-pipe combo
After market cams
Timing advance (not sure how far yet)
HR Pistons (to raise comp)
I would also get the rotating assembly balanced
HR retainers & shims
Phenolic spacers
Big bore MAF housing

I've been lurking this forum for awhile now. My questions are:
Is this gonna get close to 300? What else should I do, or buy or what should I not do that's on the list above??

Thanks in advance folks.

VIP Maxima

are u talking about whp? if so, its gonna be very hard. 350z guys barely do it.

Your going to need some serious luck, there are only a few 300 whp NA Z's around and there intake and exhaust systems are much better. Your going to need a more aggressive cam, a custom exhaust, higher compression, LOTS of timing, upgraded fuel system, and probably a few other thing I forgot. Also you might look into a different tuning system, doesn't the EMU fry coils a bit to much.

Your gunna need to add some cams and SSIM to that list, maybe even larger injectors. didnt 96sleeper make 272whp n/a?

I would do a custom exhaust. Its going to come down what management you use. Your going to need something to raise the rev limiter and be able to advance timing. Your target for timing should be as high as 40 degrees for WOT. If you can balance the lower it will make for smoother revs.

Might want to add HR heads to that as well.

300hp is not likely, even if u tune the hell outta the car u will probably still be about 30hp less than what you are looking for, unless you come out w/ a mod worth 30+ horses lol j/k

And I think you'd have better luck getting their by using the full VQ35 and ECU. This way you could put even more aggressive cams and which will result in higher hp. And in the end you may need to do custom ITB's to gain more hp over the SSIM. And also get the V-manage.

DasYears

yeah, full 3.5 swap would help. but in the end, it will mostly just get you area under the curve unless you use a v-manage to retard the cams extra up top. 285hp w/full swap > 300 hp w/3.0 timing equip IMO because of the added tq, driveablility w/big cams and total area under curve

NmexMAX

iTrader: (22)

A33B + V-manage, like everyone else has stated.


I'd have to vote for new Cattmans.


Any idea which ones yet?
This would go with EMU as a given.


Those w/FAST. Mine is 'broken' The 07 (HR head equipped)Altima pistons are different than the HR Z pistons, correct? They share the same heads, but the CR is different so I'd imagine the pistons are different. nismology?

The best suggestion in here so far is the full A33B ECU swap.

nismology

iTrader: (8)

Let me qualify my statement. The type of cams it would take you to get to 300 WHP would hardly idle w/out CVTC unless you got the adapters made to dial out excessive overlap. If you do that, you're going to compromise other parts of the powerband in return for a more steady idle. Either way, dialing cams in isn't going to be as easy as getting adjustable cam gears. Just something to think about.

DasYears

exactly, with 3.0 timing you will sacrifice so much power before 6k RPM that 300whp wouldnt be as good as 285whp w/a33b timing

nismology

iTrader: (8)

You're right as well in a sense, but that would only apply if they were dialed into the fully retarded position. I was focusing primarily on the issue of idle quality. The cams could of course be dialed in to have the best possible idle quality and low-end power, but midrange and some top-end power would be sacrificed. Conversely, if maximum top-end power was the goal and the cams were dialed in as such, the idle would be VERY rough at anything below 1500 RPM, if it idled at all.

DasYears

maybe he will use medium cams with 3.0 timing and NA means nitrous available.

Of course if money isn't an issue, there's always http://www.aebsracing.com/products.p...ct=vq35stroker ...

*insert old domestic saying here*

I generally don't agree with that they say (replacement, displacement, blahblahblah) overall but for NA, it's that and tuning where the power is at, IMHO.

nismology

iTrader: (8)

^^ Don't think that's in production anymore. The new hotnesses are the BC & GTM stroker kits. In any case, the bottom line is that 300 WHP w/out CVTC @ stock displacement can be accomplished with aggressive cams, headwork, tuning, and 11.5+ compression. Idle quality and bottom end power will be in the dumps, however. Give and take...

Tatanko

iTrader: (34)

No, it doesn't.

DasYears

lol, it was obviously a string sentence: medium cams AND NA means nitrous availabe. you know, ?? obviously NA doesnt really mean nitrous available

Tatanko

iTrader: (34)

My bad. Didn't come across that way

DasYears

yeah haha, i noticed that when you posted, but o well. lol

hacim105

iTrader: (6)

I'm glad you understood what I was saying about going with the full A33b. Some didn't immediately understand the purpose of that is to have a higher level of aggressive cams and retain a near normal idle and low/mid power.

That's why i'm jealous of the new Z's with the variable intake and exhaust cvtc. Their cam possibilities will be even better.

DasYears

even better, the g37 has the same number of cam profiles as the brand name suggests...infinit(y).

your not goin to see 300whp. sorry. oh and for the money invested your better off spending it elsewhere imo. good luck tho!

nismology

iTrader: (8)

Any particular reasons why not?

Well this is the all-motor section.

Torgus

iTrader: (10)

let me rephrase that. i don't think he'll see it on pump gas.

MaxBlack97

iTrader: (11)

so now in other words ur saying on pump gas he wont ever achieve 300hp but on race fuel there is a possibility? IMO if he can see it on race fuel he can make it on pump gas

Torgus

iTrader: (10)

look i'm all for it. i just don't think seeing 300whp na in a maxima is likely if at all. other than stroking it.

nismology

iTrader: (8)

It's been done in the 350Z realm on pump gas. It can be done in the maxima realm as well, on pump gas.

Torgus

iTrader: (10)

afaik it's only been done by 2 350z and there breathing is better on both sides. which is why i think we would have to do it on racee gas.

newbie 3.5 question with all the damn intake mani's from the vq30 did they do the same with the 3.5's to like mevi, Vi all thats ****?

Sprint

iTrader: (10)

its not going to be worth it with all the money you are going to spend

nismology

iTrader: (8)

It hasn't been more common in the 350Z world because people are afraid of it (seems too radical) or don't want to spend the money to build a motor. Ditto with maximas.

And the ones that have done it are non-revup 350Z's which are indentical internally to maxima VQ35's. Any mod that they can do, we can do with the exception of headers (obviously). The modded FWD IM does better up top than the stock non-revup plenum/collector IMO. I guess we'll have to agree to disagree.

hacim105

iTrader: (6)

I disagree with this statement. To have a 300+ hp NA maxima would be amazing. Anyone can slap a turbo and fuel system on a car. Making 300 hp in a FI'd 6 cylinder car is not that impressive, because it happens all the time.

But to make 300 hp NA takes more time, skill, knowledge, research, etc. Yes it takes more money but there is much more mad props with it.

hacim105

iTrader: (6)

I think I understand what you're saying, however, I don't know what you're talking about when you say ALL the IM's for the vq30de. There is the stock IM, the MEVI, and the 00VI. All of which were produced by nissan just for different cars. The stock IM also know *** the USIM was for the maxima here in the US. The MEVI was in maximas overseas and the 00VI was in the 2000 and 2001 maximas.

The 3.5 has the IM that comes on FWD cars, another for RWD cars, and one that was on the SUV's. The one on the SUV's wont work without the heads. The RWD needs to be modified to fit. Hope that clears it up for you.
