I do think it's pretty cool that someone took the time to go the route you did. And I am not trying to bash you for it. I just want the public to know that the two projects discussed in this thread are just two of a few different ways to skin this cat.

Tilley- The WHOLE harness/ECU/key cylinder/IMMU/gauges/etc. was swapped...at least it was when his brother maxS swapped the 5.5gen VQ35 into the 5th gen.
So, I'd say the wiring was probably pretty minimal.

Elaborate, please. I have all the intelligence of a rock when it comes to this... which is why someone else will be doing it for me.
I have a 1995 5-speed and my main problems are that
a) I want to keep my 5-speed tranny
b) The mention of Wiring, ECUs and all that complicated stuff causes my brain to violently rupture. I'm used to old 455s and carburated engines... Sad, really.
Just dumping a 3.5 block without even thinking about the wiring would save me some headaches but I'm really interested to know how you'd do it... be specific my IQ is lower than a Honda's torque curve right now

Which is why I'd go with 3.5 block only... I mean, keeping as much 3.0 stuff as possible will just make things easier.
Plus, the extra compression. 5.5 gen engines fit in the same engine bay and have 255HP, so with the extra compression and aftermarket headers/cat/full catback... would 300HP be possible?

First of all, it's not 255 to the wheels so it would take a lot more than some exhaust mods to reach 300 hp. Second, the VTC gives the 3.5 a lot of that horsepower. So no, just dropping in a 3.5 block with 3.0 heads and calling it a day would not be the efficient way of doing things. Easier, yes, better, no.

I never said it had 255 at the wheels.

He still got a 13.8 timeslip without the mevi...
As for dropping the whole 3.5 without the VTC in, why would you want 3.5 heads over the 3.0s?

I have to dispute this cause first off the 3.0 has a completely different cam pos sensor (oppostie side of head and has different pickups) second 3.5 flywheel has completely different teeth for the CPS 3.0 has 360 teeth and 3.5 has I think 3 teeth that are huge and 3 small) also the TB but that can be modded too work. I was thinking the same as you SR20DEN but then after looking at it its hopeless.

I am pretty sure that the valves are bigger on the 3.5 heads as well as a safe everyday drive compression ratio that wont give you problems in the long run, and since gas prices are as high as they are why would you want to have to drop in octane booster everytime you fill-up? Kind of a PITA if you ask me.

The 3.0 ECU needs to see the sensor on the front cover, the 90º reference and the 1º crank trigger. All of which can be swapped over.

SR20DEN - I think your way is BETTER since VQ35 heads flow/cooling is superior, but using only the VQ35 shortblock and VQ30 5spd trans would be the easier route.
Why someone with a 100K+ mile 4th gen in your area wouldn't jump at your cRaCK ***** pricing/slave labor is beyond me.

Mine has 115K miles but I'm in Canada...
What about the new VQ40? Why couldn't we take a 3.5 bottom end, stroke it to 4.0 and put 4.0L pistons and rods in with 3.0 heads, wiring, ECU and tranny...

3. 5 speed fly wheel is too far away from casing that them input shaft for the trans on goes about 3\8 of an inch into clucth disc which if your making power is gonna strip the splines
4. clutch wont disengage cause its too far away from trans and when it is pushed in it causes the throwout bearing to get caught on the outer sleeve of input shaft.
These are all problems that come into play I know from experience so dont flame me if you havent tried it.
