The reason I say to run that ECU, is simply to reduce the wiring nightmare. Few reasons... The VQ35 ECU uses drive by wire technology. This would mean wiring in the gas pedal and making up a subharness for that. The biggest thing, is that ALL VQ35 ECU's come with NATS (Nissan Anti Theft System), which uses a transponder key and matching IMMU. Basically, you would have to get a ECU, IMMU and key, ALL from the same vehicle in order to just start the car. Now, if you have a Consult, or access to one, this isn't such a big deal. However, it still has to be wired up.
If you use the VQ30 ECU, you can get away with using the VQ30 pulley. You have to make a mount for the crank trigger pickup sensor.. but, it's not hard. You don't have to switch the timing cover over.. You use the VQ30 flywheel and VQ30 pickup sensor. This will let you run the VQ30 ECU.
So, using the VQ30 ECU drastically simplfies this install. Yes, you will lose your VTC.. but, it's not THAT big of a deal. You might lose 5-10ft lbs in the low end/midrange. Using a 96-97 ECU means that I can have clark at JWT tune me a nice map to suit the VQ35's demands. So, besides the loss of CVTC function... it's really the best way to go IMO. I mean.. I don't mind wiring up a VQ35 ECU and harness... I had to wire up the NATS system in the Sentra.. and get that working. But, for the average Joe... I don't think most people would enjoy wiring one up. Unless you're really good at reading/interpretting wiring diagrams and voltage/resistance values, adding in resistors/etc where needed... this wouldn't be for the faint of heart.

lose the vtc? your not done bud... u made something pretty good there but finish the thing.. if some shcmuck in a crx can make his vtec work then u can sure as hell make a jumper harness for that vq35 ecu to work.. not sayin anyhting negative about your swap i like it as a matter of fact but "Make it happen capt".

Trying not to get off topic here, but why would you want to use the VG anyways? Besides a marginal cost factor, the VQ30 would even be a better alternative than the VG IMO. The VQ35 is just straight nasty.

Well if that wouldn't pull the teeth off third in a B13 box I don't know what would. Probably want to plan on a swap to the now virtually nonexistent P11 gearbox. And, the six might indeed be a tad heavier than the four, but my goodness it oughta be interesting in a straight line (accelerating, not stopping - well come to think of it, that might be interesting too - - ).
I STILL think it's a cool idea ***; there may be a few folks out there who'd have a great time with it - I know I spent about that all told on my VE swap.

If you don't have the patience
to do it right the first time,
how is it you have the time to
do it over and over again?
just a word on the CVTC thing, how about a set of JWT cams? will they not eliminate the CVTC? maybe i'm way off, i havent paid attention to VQ/VE/VG maxima stuff in about a year now.
also, look around on maxima.org for tilleys99, hes been doing VQ35/VQ30 hybrids for a while.
IIRC, a real nice(read: painless) setup is VQ35 block, VQ30 heads, JWT cams, MEVI (middle eastern variable intake manifold).
all of the VQ stuff is real cheap considering its durability/quality. apparently they're real easy to build too.
make this setup for a P10 and i'm in, otherwise i'll have to wait and find myself a nice B13/B14.
how is the clearance in the enginebay of the spec V? enough room for say, a reverse ypipe and an SC61? maybe a nice intercooler and some pipes??:evil:
i'm very interested in the outcome of this project.

The difference between turning a solenoid on/off, and pulsewidth modulating a continuously variable cam solenoid is HUGE. Vtec is on/off using 12 volts.. that's cake.. just like engaging VVL solenoids.

i believe if youve gone this far with this project you can do anything man. the more you perfect it the more demand youll get for it when people see it hauling ass, or hear it driving by. i fu*k with you bout sc61 but seriously. perfect it.. sell this
Spec'S need all the help they can get

or maybe use what he says to use....

I am very interested in the install kit for a Specv to VQ35. I have both at my disposal and would just need to install kit/instructions and I guess wiring.
Please e-mail me the details ser5150@msn.com
I have a 2005 Spec V Nismo Header, Cat back and cold air right now.
