I have this 2.62 pulley just sitting in my room looking at me and trying to tempt me. I started reading up on my350z and it seems that the smallest any of them have gone is the 2.87 and they are running a intercooled setup. So now i have this brand new 2.62 sitting in my room and i want to install it, but that would mean a intercooler would be necessary imo(so i don't have to pull a shat load of timming). That means that would be around another $300 for intercooler & remaining mandrel bends i would need. On one hand i want to push the setups potential, but at the same time i have become a little gun shy since blowing my motor. Just want to be safe since i don't plan on going through this again.


Any input guys?

 

start safe and work from there? maybe a larger pulley, see how it goes and then work down...

 

You have the W/A injection so that should make up for the lack of intercooler for the most part. If you really need you can probably increase the jet on the spray somehow.

You should also be able to pull timing to make up for the extra boost and heat. I am just saying which is easier swapping out the pullies or changing a few numbers on Emanage? IMO put the 2.62" and get the tune right. Its not like you boost ever anyway.

 

Yea but when i do look what happens

 

Chris, don't do too much at once again. Remember what happened last time

 

I wonder what the timing advance looks like on a 5.0 gen vs a 5.5 gen. Is the 2K-2K1 timing the the same as a 4th gen? Eng92 gaves us some good info in this thread for 4th gen vs 5.5 gen timing advance http://forums.maxima.org/showthread.php?t=457652

If a 4th gen and 3.0 5th gen share the same timing then from what Eng92 showed us your gonna be running more timing than what a stock 3.5 does. So that is not good. I would definately pull some timing if that is the case

 

Wrong thread...

 

I wouldn't put on a 2.62" unless you are going to pair it with an aftercooler. The aftercooler will provide safer boost and less boost (through the ~1-2PSI loss). Then all you need to worry about is your blower being able to handle a 2.62".

Good luck.

 

He is running Water/Alcohol Injection so that should help him with charge temperature.

I am torn a little the more I think about it. I know that you shouldn't push this setup too much at first and shouldn't do too much at once, but then again I know you are going to want to do it eventually and how lazy and impatient with cars you are to take the SC off the bracket. I would say go for it since I know you aren't going to push it too hard and are going to try to get the tune, etc. right, but it isn't my car and after the blowing that motor I know you don't want to do that again. Your car is going to be really fast either way. I would also consider the auto is going to be pushed pretty hard either way.

 

You just blew your motor, right? Get a larger pulley and get yourself up and running safely. When everything good for awhile and you get bored of the power you can switch to the smaller pulley and add an intercooler.

 

yep i know which thread you are talking about mike. I was really suprised by that since all i have heard about is how the 3.5 swap guys are complaining about lack of timming.

 

honestly I wouldn't even start with a 2.87 once you get the 3.5 running correctly. I would start with say a 3.25 until you get all the bugs worked out and get some kind of timing control. Its going to be a whole different world of boosting than what you where used too with the 3.0l.

 

Are you talking power wise or difficulty in tunning? I am going to be using the emanage timming harness to pull timming

 

power wise you will make more with the 3.25 pulley than you where making with the 2.87 on the 3.0l. Tuning isn't difficult once you see where your timing is using the 3.0 ECU on the 3.5. Not sure how difficult it would be but I would try to get in touch with a 350z driver running a vortech tuned setup and try to match timing curves with them. Hopefully it will be close from the start, guess you will find out soon enough.

 

yeah but i am a power hungry ***** . Thats what i planned on doing was getting a timming map from one of those guys and using it as a sort of base map to work off of.

 

I would get everything dialed in first before going too extreme. With the 2.62 you would make over 400whp easily and more than likely almost 100 more ft lbs of torque vs the 3.0 which I dont think your trans would hold.

 

haha, i am not going to be too sadd if that tranny blows. I just need it to hold on for like a month or so till spring break then i hope she goes kaboom. That way the old man want put his foot in my a$$ when he finds out i am doing a manual swap. I pay for everything, but technically he "owns" the car

 

It will hold, just take it easy if thats possible. My 2002 trans lasted about 2 months laying down 396 ft lbs of torque.

 

You put down 400lbs of torque with a SC? Wow! That must have been the T-rim

 

nah that was w/ his nitrous setup on his 2k2. That is pure abuse for a auto

 

Naa that was my nitrous setup on my 2002.

 

ahhh, I totally forgot about your old car.

 

Running 2.62 for an entire summer and this winter! on a 40,000mile blower no problems- 15 psi intercooled through Spearco. Now I just gotta work on tuning-it is a really safe to safe -tune right now!
