What do you guy think it would take in mods to get my 2000 Max up to the same HP as my Ma's 2002? The reason I ask this, I drove my moms the other night and what a difference 33 HP makes.

 

CAI and a Y pipe. $600.00 +/- should get it done.

 

with mods, you may be able to approach similar top-end power, but I don't think you will be able to get close to the low to mid range grunt that the 3.5 engine has....

 

thought u want to get 2002hp out of a 2k

so both 2k and 2k2 are auto?

 

Yea they both are Autos

 

2000 Maxima
222 hp stock+
15hp Y pipe ($400)+
6hp intake ($100)+
8hp UDP ($175)+
3hp Catback ($100)=
254hp ($775)

Ballpark figures, but taken (and readjusted) from Stillen catalog.

 

Where can I get a Cat-back for $100?

 

Me wants one two. Catback for $100, let the Rubman in.

 

Just a catback without a muffler? Any muffler shop can custom bend one for you. I paid $221 for them to install the muffler I brought them ($50), add on a resonator ($75) and build me a custom catback and install it ($95).

I ended up putting my stock muffler back on because it was so damn loud, but if I had to do it all over again, I would pay ONLY the $95 for the catback with no resonator. They can always add a resonator later.

 

Would a catback on its own add any H.P., if so how much?

 

There are different theories on this. Here's mine.

The catback seems to have a few restrictive bends in it. I think that the stock muffler is extremely well designed (as did my muffler shop).

IceY2K1 told me that someone dynoed the 5th gen with and without the stock catback/muffler and only gained 3 hp by taking the stock one off. My feeling is that the 3 hp is lost on the stock unit mainly in the catback.

Here are some pics of mine....

 

Think I'll get one made if there is actually any H.P. gains to be had. Thanx for the info.

 

With those mods, a 2k2 should still take out an 2k-2k1. The torque curve on the 2k2 is better. I havent seen a 5th gen break 14's with just bolt ons. (Automatic/2k-2k1)

 

If only life was this easy. How many 2000's with these mods do you see with 215 hp? Thats right, none. Dont beleive everything you read as speicailay if the info is coming from a vendor.


Also I posted info on my before and after dynoes with my greddy exhaust. I gained 10 FWHP and 11 FWTQ..

 

The most HP I've seen out of a 3.0L 5th gen was I think 205 HP at the wheels. That car had ypipe, intake, UDP, exhaust...basically all the n/a upgrades. That translates to roughly 240-245 HP at the crank. This is basically the most you can hope for on a 3.0L 5th gen. Although this doesn't quite match the rated HP for the 2002's (255), it does match the actual dyno'd HP for them...the 6speeds seem to be dyno'ing around 205 at the wheels on average.

So, in short YES with all the mods your 3.0L 5th gen can match the ACTUAL HP for a stock 2002.

 

Here's what I have:
FrankenBerk Intake
Stillen Y Pipe
2 1/2" Catback
Unorthodox Racing UDP
Stock muffler

I'll be going in for a dyno run when it cools down a bit. I'll post it up here.

 

So which gain do you disagree with?? The Y pipe?

 

Even if you did this, it wouldn't "feel" the same. What you are really feeling is a very generous torque curve that comes on early.

People buy hp, but they drive torque.

I own a 2k2 6-spd and a 2k 5 spd and the low-rpm torque on the 2k2 is night and day with the 2k.

 

Install a super charger!!!

 

What about a High Flow Catalytic converter? Randam technology advertises a 20% hp increase because it's much less restrictive than the stock one. Im sure thats optimistic, but Im sure there is some HP to be gained.

Ill let you guys know the difference i feel when i get my Y pipe and RT cat installed tomorrow...

 

that'd be me

 

I haven't had mine redyno'd since I added the udp, rt cat and b-pipe and switched to CAI.

With SI and Y pipe, I put down 203.7. I imagine that when re-dyno'd, I'll be around 215 AT THE MOST which is what 255 should put down with 15% loss.

dyno

However, no way can a 2k/2k1 make up for the torque loss.

As for no 2k/2k1s in the 14s with just bolt ons - that is just pure nonsense. Of the three 2k 5spd here in tampa that regularly go to the track (that I know of), all easily run 14s.

 

Well said its the torque and torque curve not the horsepower, that makes the 2002/03 quicker and feel quicker to ya.

Not stock but they don't have many mods either.

 

One thing I have learned from modifying my Mustang... You can NEVER trust the HP gains reported by a catalog or a manufacturer.... They usually are just all lies.

 

Yeah, those numbers in the stillen catalog are B S. Just doesn't happen that way.

But still, a 2k/2k1 5spd with all bolt ons should dyno around 215 .

 

Hmmm...well, I dynoed 190.1 to the wheels, and I'm an auto. With 25% drivetrain loss, that should translate to about 254 at the crank. Those numbers were with JWT intake, Cattman Y, and UR UDP. I would say the CAI probably gains a little over the Hi-flow, but I'm not sure how much. So I would say it's possible, but you'll never get the torque out of it N/A. That would be the bonus of that extra half litre. If I ever get my 5spd swap done, I'm going to have it dynoed, but I wouldn't expect any better than 205 or so. Guess we're screwed...
