i was readig about a stroker on a 3.0 block with the 3.5 crank and rods...did anyone try this and was it successful???

i have a 3.0 motor and was thinking of it, but then i had an idea......how about a 3.0 block with a 4.0 pathfinder crank and rod??? will this work??? or how about a 3.5 block with a 4.0 crank???

i want a stroker kit but the one that aebs is selling is too much.....let me know what you think....

 

No and no.

The VQ35 crank and rods will fit, but it will push the piston into the head or extremely close to it. Won't work without a ton of work and probably won't be worth it over s regular VQ35 swap.

The VQ40 would have even worse problems. The VQ40 has a bigger block. Since nissan had to design a completely different block just to fit it, something tells me it is not going to fit in the VQ30/35 block. There was a shorter stroke on every aftermarket stroker kit I have seen for the VQ35 than the VQ40 has stock.

You can use the VQ30 crank and rods with the VQ35 block and pistons, but this will be lower compression and a whole different story. It would be good for a turbo though. I think Tilley is trying it on his turbo car.

 

Tilley is doing a 3.2L. He is using the VQ35 block with VQ35 pistons, but a VQ30 crank and rods instead (better revability, stronger rods). The opposite (VQ30 pistons and VQ35 crank) would give 3.3L. The 3.2L would be a great N/A motor for someone that likes to rev the f*ck out of it like Krismax, and probably an awesome FI motor too, basically the best of both worlds.

 

IMO a 3.5L woud be easiest bet, drop it in like Mr Claw.

 

The VQ30 rods are not stronger. They are just not put on as much stress as the VQ35 rods with its longer stroke. Remember the Vq35 at ~7200 is the same piston speed as the VQ30 at 8000.

The VQ35 rod bolts tend to be a weak link though. The VQ30 has stronger rod bolt/nut for the piston speeds we see.

Moral of this thread is unless you can build and customize you own motor, just swap in a normal VQ35. A VQ32 hybrid brings the piston into the head and the VQ33 hybrid is lower compression. Neither is really suited for the majority of people on here. Changing the bottom end is not worth it until you get really serious.

 

I do believe SR20DEN was testing stronger ones from ARP, right?

Other way around

 

I just possibly found a cheap alternative too better rods for the 3.5 just need too test it.

 

1.9mm Pwns jOO!!!

 

I know i workin on that.

 

Tilley how much is a full 3.5 swap cost in labor and parts? How long does it take for a full swap? Thanks
