^^^The 6th speed is better for cruising on the freeway, but puts less power to the ground than the 5 speed. It's not a big difference though, maybe 3-5hp.

I think 00MaxSE should either upgrade to a 5.5gen with a 6 speed or "downgrade" to a 4th gen. By the time you're done with everything, swapping in a 3.5 into a 2k max will be almost the same as just upgrading to a 5.5gen. We're prolly only talking about a few hundred dollars difference, so a 6speed would be worth it. If you want pure speed and to save a bit of money, go with a 4th gen.

 

If you absolutely want to swap, go with a 4th gen. Shaving 200 pounds is easy, and that will bring the weight down to 400-450 less than a 2k. If not, buy a 2k2 and call it a day.

Another advantage of the 5-speed is the lighter flywheel and solid, 1-inch thick shifter rods instead of cables. Feels better jamming it into gear, and from my experience, seems to shift quicker.

 

I definitely agree about the rod linkage being better, but I did not know that the 6 speed puts down less power to the ground. Where did you hear that, foobeca? I'm assuming it's just because of the gearing and heavier flywheel.

 

200WHP is a brick wall for a DE-K ? Have you ever seen a dyno chart of a DE-K with light weight wheels- STOCK ? Lets say 15" steel wheels on dinky 205-60-15 Potenzas that came on the GXE 5spds, do you know what they put out stock ? bout 10WHP less than 6spd 3.5Ls. One .org member got 198WHP stock out of his and posted a dyno chart on the .org while back. Ya all gotta remember most 3.5Ls out there do not have every mod SR20DEN has, like flywheel, pulley, light weight wheels, AC and alternator bypassed for the dyno- which all add up quite alot of power themselfs. I know how much I gained from installing a Fidanza and UD pulley on my car- whopps I forgot I FREED up HP by installing these items. Nissan performance mag got 15WHP across the line and in some parts of the powerband up to 20WHP from JUST a flywheel on their 3.5L Altima. I am not going to be telling people what my car puts out, but I will try to post my video of what it looks like going mid 13s in a 3.slow 5th gen all motor. I'm going back to the strip this week.

 

first SR has stock flywheel unless its some secret he told you second he has never taken alt off. and i believe hes dynoed with stock 17's and got 25X's.

Ok get the times and post them ,I have ECU ,underdrive pulley ,stillen intake ,midpipe ,y-pipe,and b-pipe with greddy muffler.
i have no tuning and still have stock exhaust manifolds.I put the same exact mods on my 3.5 and ran 5 tenths faster and thats using a 3.0 ecu to run 3.5,UNTUNED.

I will be going to track weds with slicks (ive never used them) and see how much faster i can run over my best 13.35

 

I don't know exactly what your mod list looks like but i know it includes some extrude honing, plus ALL the bolt-ons plus a/f tuning. The fact that 3.5's dyno so low stock says more about the restrictive pre-cats and stock IM than it does about the motor itself. Headers, that's an extra 20 WHP right there. You're looking at 240+ WHP with simple bolt-ons. It'd be higher than that if the 3.5 had a better intake manifold. The stock manifold is tuned for mid-range grunt, not top-end. Please name some DE-K's that are putting over 215 to the wheels with JUST bolt-ons.

If SR20 had extrude honed parts of his motor like you did and had an aftermarket flywheel he could've had at least another 10 WHP easily. The 3.5 heads flow better, weighs less, has less reciprocating mass, has a lighter valvetrain etc. so it's not just a bigger motor. It's better in almost every way. It's just not as smooth...who cares?

And just for the record, SR20DEN had the stock flywheel when he dyno'd that 263 WHP. It's so heavy that he proved the his car made more HP in 4th than in 3rd. Talk about inertia...

Why don't you tell everyone your COMPLETE mod list and give as a dyno chart to examine cus until then, you're full of it...

 

I will give ya a timeslip sometime this week, it should indicate fairly well what kinda power it makes vs my traps.

BTW there was a 3.0L at Maxus that dynoed over 240WHP with low compression pistons, I am not claiming to have 240WHP or anything (nor will I ever reveal my dyno charts), but to all of you who think 200WHP is a brick wall for a 3.0L- you need to check yourself.

If I can make 200WHP with bolt ons on a SR20DE, I sure as hell can make lousy 200WHP in a DE-K. Moddying Japanesse/ German cars isn't something I picked up ONLINE like most of you did, I work in the trade for a living- for longer than 99% of the people who posted here- DRIVE !

 

That's pretty unfair, since 6-speeds have more drivetrain loss and some damn heavy 17's. Give them the same transmission and the same wheels and they'll definately be putting down more than 205whp. That's why I'm keeping my 5-speed and sawblades.

SR20DEN has the stock 26 lbs flywheel as far as I know, and I'm pretty sure his dyno was on stock 17's, which weight quite a bit.

So you ran mid 13's on street tires with your 5th gen? Congrats. Do you have a full timeslip? I'm interested to see the trap speed, 1/8th and 60 foot.

Also, none of us have 3.5 4th gens have light flywheels so why would you be compairing our numbers to yours? Shouldn't we be comparing mod for mod? What did you put down with H/I/E and no tuning at all?

In fact give us a complete mod sheet so we can see and judge how much work and money you have on your car, vs the results.

I'll start:

VQ35 swap, Cattman headers & Catback, PR CAI, no PS.

Stock 2k2 intake manifold, stock ECU w/ 6550 rpm rev limiter, no A/F or timing tuning at all.
No weight reduction, full interior, heated/power seats, sunroof, ABS.
Yokohama 215/60/15 Avid T4 mounted on the stock sawblades.
Stock Suspension.

Those runs were done on true, 100k mile, rain & dry, everyday street tires, in absolute street trim, with 25 psi in the front tires:

Best MPH (Left) Best E.T. (Right)



The second timeslip is a bit pale, but if you look closely it indicates 8.88 for the 1/8 mile and 13.680@104.54 for the 1/4th.

I have done considerably better on slicks, but I'm talking about absolute street trim here, since I assume that's what you're going to run.

 

I'd like to see a timeslip AND complete mod list. Kthx...

Even if a DE-K makes the same peak HP as a 3.5, the 3.5 will always have more area under the curve. No replacement for displacement there...

I call BS on the 200WHP SR20DE with bolt-ons. Every single one of those that's approaching 200WHP has AT LEAST JWT cams and high-compression pistons and perhaps a stroker crank. Bolt-ons, try again. SR20VE maybe, DE not a chance. If you call those things bolt-ons, your credibility goes out the window right there...

Once again, mod-list please.

 

JWT cams are not bolt ons ? Let me put it to you this way, JWT S6M cams gain bout 45WHP over stock cams when combined with a HS Gen 6 race header. Stroker JWT engine with high compression pistons, cams, special ECU tune, and 02 induction RACE intake manifold has pushed over 250WHP and was still able to pass emissions, cylinder head was stock unmodified. There are bout 30WHP still hidden in the cylinder head to be exploited by Dan Paramore Racing.

My Mod list-
4 stroke 6 cylinder aluminum block and head engine, using a plastic composite intake manifold with bored out throttle body installed in a 4 door family sedan.

Just like you will never be able to find out what SR20DEN has done to the intake manifold on the 2k2s, I will not tell you my lil secrets- and extrude honing the intake manifold gains you 5 whoppn WHP at peak which I guess to some of you is mad powa.

 

I know what SR20's mods are, and i know for sure that your mod list is more extensive than his. With the exception of a better intake manifold, 3.5's will make more power mod for mod. More displacement, heads flow better, more efficient valvetrain, less reciprocating mass. It's unfair for you to compare your heavily modded 3.0 to bolt-on 3.5's with stock 3.0 ECU (which runs far less ignition timing than the stock 3.5 ECU) and no tuning. Like i said, until you're willing to tell us how much power you're putting out and your mod list, you're full of it and have ZERO credibility.

And no, cams aren't a bolt-on mod. It's considered an internal modification.

 

Building a Maxima from scratch is "bolt-on" according to BlackBird's conception, as long as you have someone else do the welding. But that's cool man, as long as everyone else understands what you mean and you don't try to be deceptive about what mods you have.

 

I call B.S. on the 240whp NA on a DE-K unless it's revving to 8k and somehow you find a way to have it keep making power up to 8000rpm.

DE-K 3.5
stock 180whp 205whp
typical bolt ons 200whp 230whp
+ tuning 210whp?? 260whp??? maybe more

I like the 3.0's smoothness, but I like the 3.5's grunt. You can't just compare peak numbers. A stock 3.5 might only have a few more horses than a modified DE-K, but has a lot more torque. I would rather have a engine that is 205whp/230wtq than an engine that is 205whp/190wtq.

It's been said a million times, but there really is no replacement for ...... Every mod you put on an engine will have better results with more displacement. A WAI/CAI might only give you 3-5whp in a vq, but can give you 10-20whp in a big V8.

Blackbird, I don't know why you're a 3.5 hater. Both engines are awesome and can make nice power. But the one with the larger displacement always has more potential.

 

yes 240whp 3.0 is real but FULLY built ,but with turbo comp pistons so that hurts.

You could get 300whp with a 3.0 but you could get 300whp on a 3.5 much cheaper

 

Iam wondering do the 4 th gen 5 speed trannys bolt up easy to the 5.5 Gen?

 

Yeah......

 

explain a little more.... about the 5 speed is it effeciant with the 3.5 in terms of can it handle the 3.5's power

 

Yes it can handle the power. Almost everyone here with the 3.5 swap is using the 5spd. You do need to get a better clutch though, can't use the stock one.

 

The VQ30 and VQ35 are damn similar. People have put 6-speeds in their 4th gens so I suspect it would be a snap to mate a 5-speed to a VQ35. But you'd definitely want a 5th gen 5-speed because they're stronger. Plus you can get LSD with the 2001 AE tranny.

 

Why would you use turbo pistons in a NA engine? That would kill your power.

There is no fricken way you are going to get 300whp with a 3.0 engine without FI. That's almost physically impossible. Hondah gets 240chp with their 2.2L s2000 engine and it has to rev to 9000rpm to get there. 240chp ~=200whp If honda can't get 220whp out of a 2.2L engine, what makes you think that somehow you can get 300whp out of a 3.0L?

 

Iam looking to replace my 2k2 auto tranny and heard the 6 speed is a PITA to swap, so im thinking a 5 Th Gen 5 Spd Lsd with fidanza flywheel and a good clutch, car should run awsome.

 

umm, a 5spd swap is no walk in the park either.

 

I never said it was but it is easier and cheaper then the 6 speed swap IMO

 

Yeah, and the 5 speed has a rod linkage instead of a cable linkage. I don't know much about cable linkages but I can't imagine they're as reliable or simple as rod linkages...

 

i'm nto sure about the power of each engine, 30 VS 35, and what they're abilities are, but i know that i want a lightly modded engine that will make my car capable of flat 14s. VQ35 swap with h/i/e and a lightweight flywheel and clutch. maybe this won't yeild me to flat 14s, but will this make me faster all around the powerband than a 5.5 gen 6spd?

the swap does seem pretty straight forward, besides the few mods we'd have to do (fuel rail return system, cam spacers), i want more power for my 5th gen without HEAVILY modding it.

 

if u have a 3.0 with every mod possible plus a high enough compression and high enough reving its possible and maybe better gas

 

OMG. Wow. Can a mod PLEASE clean this thread up by deleting posts 95 through 104 with the exception of post 100. All this tranny crap cluttering this thread up.

99SE-L if you have a question that's beside the main point of a thread, start your own.

 

Put the crack away before the crack puts you away. There's no way you're going to get 300whp with a 3.0L without boost or nitrous.

I don't think you could get 300whp with a 3.5L either. SR20DEN with his secret sauce IM and a ton of mods gets 262whp.

 

He said himself that 300whp might be possible.

He still has stock cams, stock flywheel and stock wheels, so perhaps 280+whp.

And there's a 350z that put down 295whp N/A with cams, plenum, tuning, and bolt ons.

 

I wasn't ruling out the possibility on a 3.5. But 300whp with a 3.0L is flat out impossible.

 

Nissan has the Race VQ30 with 450hp. NA

 

Actually I think that's 415 HP at 8500 rpm.

And you can bet that engine would set you back 5 digits. But you'd be pulling 11's all day long.

 

and I'm sure it uses pump gas right??? Link please??? I did a google search and I could not find any credible source for a race version of the VQ30 having 415hp.

 

BlackBird: Got some slips yet?

 

Nope, I will thou ! Its been raining here today like crazy, and last nite we had some big winds with me working late I didn't have enough time to go and tech the car. I will try to do it on a cool nite. Monday-Tuesday where warm and would offset race gas program I uploaded

 

Go on weekends, the track is sticker.

Race gas? Pfft. I run my car with 91, junk in the trunk and a brake dust shield trying to fall off.

 

 

Don't hold your breath waiting for that timeslip. No mod list, no dyno chart, no nothing. This guy is...........meh.....not even gonna say...
