Nissan VQ35HR engine swap
The 3vz-e engine in my 93 5spd toyota pickup has been under a lot of stress recently, and I've been considering replacing it with a Nissan VQ35HR engine. Any thoughts?

Nissan has announced it’s new next-generation V6 engines for front-engined, rear wheel drive vehicles. The new VQ series comes in two displacements - the 2.5 liter VQ25HR and the 3.5 liter VQ35HR. The engines will make it’s debut in the new Nissan Skyline (no, this is not the new GTR) and the Infiniti G35 this autumn.
Improvements include reduction of weight and friction through adoption of asymetrical piston skirt configuration, reduction of piston-side force through lengthening of con rod and the addition of a rudder frame, newly-designed cylinder block with improved cylinder block. Friction is reduced via the use of the world’s first hydrogen-free, diamond-like carbon coating.
The intake valves have continuously variable valve timing control (CVTC) while the exhaust valves have electromagnetic valve timing control (e-VTC). Not sure what the difference is between these two technologies. Intake resistance is reduced through symmetrical twin intakes, and straight intake ports. The exhaust manifold design has also been improved.
The HR in the new engine codes mean “High Revolution”. While the previous generation VQ engine, the VQ35DE had a redline of 6,500rpm and made it’s peak power at 6,200rpm, the new VQ35HR will rev up to a 7,500rpm redline. No power figures were quoted by Nissan, but expect the new VQ35HR to make more than 300 horses. In fact, the number should be about 306hp SAE, which is what the 2007 Infiniti G35 which uses this engine is supposed to be putting out.

Unfortunately I'd say the swap is about as possible as putting in a Laborghini V-12, as in sure it might be POSSIBLE, but you'd have your work cut out for ya. Why not a 1UZ-FE or Supercharged 3.4, they both are in the realm of possible swaps, and proven powerplants.

Do any of the newer toyota engines use timing chains? Most toyota motor's I've had start having a lot of crank seal sleeve problems as they accumulate a lot of miles. I'm annoyed with having to have the timing belt service done frequently too... we put a lot of miles on these engines (like 50k / yr). Perhaps we should just buy a nissan truck?
THE TRAITOR!!!

i doubt the "krazy" in your glue is enough to make it stick.
i 1000% agree to do a 3.4L swap before the VQ.
the motors are also found in some maximas (best donor source) and altimas besides the 350Z. ALL of the driveline needs to come from the donor, inc ECU, pedal, immobilizer, etc...
im laying the groundwork to drop one in my 510
