6spd, VQ35 swap on a 4th gen

6spd, VQ35 swap on a 4th gen
I've gone through the all motor threads but I cant seem to find anything on this--
My question is: Is there any fitment issues or any other problems I may encounter by doing a complete swap(6speed tranny, VQ35, ecu and wiring harness)?? I'm under the assumption that's all I need... other than upgrading my fuel pump. Has anyone done this??
I'm looking to either doing the VQ35 on my 5spd or a complete engine and tranny swap.

I am intrested in doing this as well. It use to be said that a VQ35 in to a 4th gen could not be done and now look it seems like everyone is looking to that route. So seeing that there are at least a couple of members who have preformed this swap we know it can be done. But what modifications are needed is the question.
for the cuising gear!

I have until the fall before I actually go through with either swap.

The 6-speed is WAY stronger than the 5-speed and has better gearing. If you plan on doing a lot of drag racing a 6-speed with a light flywheel would be best. Also, look for a '04 6-speed as they have a 4.13 final drive instead of 3.81 (02-03). Not to mention that the 5-speed has ****ty gearing for an N/A car (you have to just barely shift into 4th. It hurts your momentum and trap speed alot).
And if you're really hardcore, there's a 4.42 final drive availble for the 6-speed. It also makes launching a FWD car relatively easier since the 1st gear is 3.15 vs the 3.28 1st gear of the 5-speed.
And finally, there's the Helical LSD available, which is muuuuch better than the Vicious for 5-speeds.
But the downside is that the tranny swap is a real pain in the @ss.

lol <--at myself...just want to make sure i'm understanding this... So all in all, if i'm putting in the VQ35, 6spd tranny, 3.5 wiring harness, and 3.5 ecu, the only modification i'll be needing to do is the tranny mount??

The wiring is a fawking nightmare. Not to mention the immobilizer, ECU and ignition switch all have to come from the same car. And then there's the E-gas. Tell you what, it's not worth it for 15 pounds of torque below 4000 rpm. My car was trapping 105 mph at 3050 lbs with me in it on a stock 3.0 ecu. You're just going to have more traction issues below 4k.
The 6-speed is a great idea, the retarded 2k2 ECU is not.

According to FAST, they are cable controlled. I wish I could find an 04+ Front end

The '04 shifter bolt hole locations look to be different according to FAST. It also looks like the 6th gen tranny housing is shaped diferently than the 5.5 gen. The starter is in toward the front of the car in an odd location. The 5.5 gen tranny is the best bet.

i don't know if the maxima people knew this or done this before but, An altima owner just installed in his 5 spd the lsd from the maxima. he also installed the final gear ratio 4.13 I think.

you can play with wheel sizes too right? I don't know much about the maxima lsd, but if you are getting traction from BOTH wheels, you don't need to worry so much about the torque.
he also did flywheel clutch combo. That will help with the rpms, right? how bad is the rpms dropoff?

mounts are different. 6 speed mount is bolted on. 5 spd mount is on the tranny and the bracket is welded onto the frame.
shift cables go through the holes in the firewall without any problems.
all the hardlines bolt into the stock location. the only thing is you will need the bracket that the clutch pedal bolts to.
if you have the parts you could do it.
and there is a parting out of a 6th gen in the parts section if anybody is itnerested.

i am not taking the vq35 so that is up for grabs.

He has agreed to sell it to me for $740. He said he preferred to sell it to someone local either way. Either way, thanks alot for the heads-up.

Sweet.
Umm, I might be making way more power than you Not with the auto but after the 6speed swap
I gotta keep it on the low till I know for sure.

Hahaha, yeah. Helicals are better because they react instantaneously whereas with a VLSD you've got to roast the inside tire a bit before it'll start to transfer the torque to the other wheel (among other reasons).
#38
I mean, I think one would be better off installing a quife (which is helical) rather than try to install the Nissan helical lsd. My opinion is that is not worth the hassle and cost either way. I'll stick with my viscous.
