the best part is seeying the faces of the z and g35c drivers when they get beat the dumbest comment i ever gotten was ata meet and a guy came up that drove a z and said "look he got the 3.5 engine cover to fit on the 3.0". i was jsut cracking up. that just proves some people are not true enthuasiasts and dont know anything except how to pay somebody to make their car look good.

Nismo3112 might be able to make a few Nissan techs heads implode where he's at. I showed some local techs (when I lived in IA) my 00VI and they couldn't imagine how we got it to work.

Cool. There should be some video from the Maxus Event. Thanks for all your comments guys. Again I must say all the props go to Stephenmax and the others that helped him. I would have never been able to do this myself.

People are pretty surprised seeing a 3.5 in my car. Not as surprised as seeing me beat a 2004 GTO and a 2005 Mustang on my all-season tires though.

American muscle guys were actually pretty respectful, Honda punks were a bit more arrogant about their 15-second cars though.

Before the run that is

Who me? Don't know yet. Tilley dynoed 233whp/230wtq with a very similar setup and I trap a little higher than him so I would assume around that.

This setup is clean. I hope Dubbya can work out the power issue.

If I remember correctly, Dubbya said 208 tq and 183 hp. The torque is not too shabby for an automatic, but the 96 ecu is holding him back at high end. A TS or JWT ecu with more advanced timing should make a significant improvement. And I need to make sure the VIAS is opening when it should.

Wow these are the dyno numbers after the 3.5 motor swap? What caused Tilley's numbers to be so much higher (233whp/230wtq)? Does he have TS or JWT ecu?

not you man should have been more clear. The guy who owns the car in the thread. the auto eats alot of the power.

But auto does not eat that much power. His car needs to be tuned bigtime. He is out about 20hp.

Yeah..a 50 hp difference is pretty significant. What was his peak HP before the swap? 183 seems about normal for an auto VQ 3.0 w/ bolt ons.

He is dynoing low because he still has the sh*tty @ss 3.0 heads as opposed to the 3.5 heads that me, Tilley, Krismax and Nismo have.

wat year patherfinder TB are you using? I know its off a 3.5 but dunno the yr. Also was there any modifications to it that was require to make it work or it bolted right up?

Anyone 3.5 swapers running Hotshot headers? I'm assuming that cattman headers works with this swap so would the Hotshot right?

2001-2002 Pathfinder.

An adapter plate has to be made in order to mount the TB onto the intake manifold.

So what's next, SAFC tuning? IMO that should bring alot out of it since AF tuning indirectly affects timing.

First of all, I need to see the dyno plots. If those are uncorrected numbers then that would explain some (probably not all) of the low power, since the dyno was done on a hot day. And it would help to know what kind of dyno machine was used.

Second, maybe I didn't set the rpm switch correctly. I tested it at low rpm and the VIAS operated, but when I reset the switch to 4800 rpm I didn't retest. My bad.

Thirdly, like you mention, the afr may need some tuning. And like I mentioned before, the timing needs to be optimized somehow.

It was done on a dynojet. Most of the numbers they gave us were STD corrected unless you asked for SAE. Also the switch over for the 3.5 is 4000 I belive.

I dynoed my car and put down similar numbers to what I got back home. The dynos were STD corrected, I asked for uncorrected dynos and it made less power. Also is was super hot in that dyno, I detonated at 6000 rpm running my more agressive B map.

But the three things I would think caused those low numbers are A/F and timing tune, its an automatic and no one was getting decent automatic #s that night, and im not completly sold on that stock 2k2 VIAS. SR's method would be the way to go for gaining alot of top end.

That's interesting. I need Dubbya to dyno here at a shop that I am familiar with.

Great, but what is SR's method? I never have heard him tell.

since the 3.5 is a larger engine, does mpg go down? and how much? i'd do this if the mpg is as good as the 3.0, with the crazy gas prices these days.
