VQ35DE 4th Gen: Shift Points and Dyno Shootout
SHIFTPOINTS
SteVTEC created suggested shift points for optimal power on most generation Maximas. Since I haven’t seen any for VQ35 4th Gens, I thought I’d create something similar using the SteVTEC format.
NOTE: Chart based on my dyno results and a 7000 rpm cutoff
SteVTEC;s Thread
VQ35 4th Gen Shift Points
Conclusion: A JWT ECU with a 7,000rpm maybe advantageous with its increased timing, but the extended rpm yields no gain (other than useless 1st gear) on a VQ35 4th gen (with my mods)
Dyno Shootout
SteVTEC also created “Dyno Shootout” charts between Stock VQ30 USIM and MEVI intake manifolds. I have appended VQ35 4th Gens to the Dyno Shootout. Its not a fair comparison due to mods, but the intent is quantify my VQ35 results versus stock VQ30.

BTW, how do like your Aeromotive FPR? What pressure are you running?

I don't have baseline VQ30-00VI Baseline dyno runs, but if I find one, I'll will add it to the list.

the stock 350z IM flows way better then the 2k2-2k3 IM. Put a 1/2 spacer and you have even better gains. powerband is moved up to 6200 rpm instead of 5800 rpm. and the placement of the tb doesnt have to be changed. you can jsut route the piping and put a filter where the coolant tank is.
and the ports are different as well. the 350z ports are bigger. the maxima ports are screwed up. the first port,3rd port,and the 5th port are smaller diameter then the second, 4th, and 6th port.
i say the Z IM flows better then VI

If I were you, ie RWD VQ, I would run the OEM 350Z IM. If it clears the hood that is.

And I choose being .05 slower over a retarded looking hood scoop.
The entire point of modding a maxima is keeping looks low key and stockish. If I want a hood scoop on my car I'll by a '73 Firebird with the 455 SD and the giant hood chicken, not a maxima.

There is a list of things I promised myself I would shoot in the cranial region before putting on my max. It's pretty short, but it includes hood scoops, spinners, giant aluminum spoilers and last but not least, lambo doors.

about the lower im for the 350z.Im thinking that it will be the same as the maxima one, unless it's the new rev up motor those are different I'm not sure though so dont hold me to it.I'm gonna mess around with it in the next few weeks.just look at it like this people said a 3.5 swap couldn't be done for cheap.Its only a matter of time b4 someone figures it out.I give it till the end of march till it becomes offical.Nuff said!!!IMHO

Oh and about the Z upper, check out my sig.
#34
IIRC there different designs.I'll check up on that.That IM design it would work but the reason why it might not fit is becuase the left side is higher than the hood is when it is closed.<this is my thought i could be wrong.
