New software to correct the FWD hobbled low end cam timing will be needed.
Hey guys this Steve...the guy from altimas.net getting with crawford Z on the fabrication of the test Product....If you have any questions i'll be happy to help and answer them if i can.
sr20den, we understand that there will be some sort of low end grunt loss involved, i cant remember the numbers lost on the Z but it really wasnt a large amount considering that most of us are running anywhere betweem 235-260 lbs torque to the wheels.
now when it comes to low end cam timing , and some sort of software adjustments ...what exactly do you mean??? what do you forsee happening and what would be a rememdy?

same concept with what we are doing with the altima at crawford Z. were either are coming up with a custom upper and lower plenum and mating it to the 350z intake manifold ...the intake manifold will be machined and "tweaked" to fit out FWD applications. then we might just use a modified stock upper/lower plenum or a custom upper and lower plenum. we just have to wait and see come next month. im dropping off the car come the 24th and they will have it for 30 days to build the test model. during that period of time , doug will determine and fabricate the pieces.
now in terms of A/F , im going to be safe and purchase safc2 or a smt6.
they are porting my throttle body also...from 69mm to 73-74 mm. just to get some more air in there. we will see what happens.

no , they will have to pay extra for the ported throttle body....but since i will have 2 throttle bodies ...i am going to be able to dyno both the stock and the modified throttle body.

manny , we dont have to use another intake manifold. we chose to since the 350z's manifold is slightly larger and gives us some room to play with when fabricating the plenums.

And also SR20den may have been able to make a good plenum setup for himself .....but where is the link for ALL of us to buy this .
I also want a plenum that peaks around 7k rpm and looses alot of low end ........

ordered the 350z intake manifold today ...so i should have it by the end of the week. just in time to drop the car off on tuesday of next week.
got a great buy on a brand new z intake mani. 250 shipped to my house. dealer wanted 340.00 so im pleased.
i will keep you posted. it might be a while for more info , im going to PLDC (army nco school) its 30 days long. so if you dont hear back from me for a while , everything is still going as planned.
