In fact, I told nurseryboy about this and he was impressed. However doing my research the final cost of doing this mod would be in the neighborhood of $10 to $15K That's right..$10 to $15K! Here's the breakdown:
Stroker Kit - $5500 Additional parts - $4.5K (manifold, injectors, fuel rail, tune, etc)Labor - $5 - $6K
Yes, I called up a well known tuner shop in NYC/NJ area to see if they could do it and they can but they also mentioned the other costs as well.
And lets not forget, this involves boring of the stock motor which means thinner walls which equals to more prone to mechanical failure. At that price unless Nissan is sponsoring me motors when the blocks crack and a shop doing the labor for free as a sponsor and all the other goodies are given to me for a discounted rate or free, it's not worth the money.
It's nice to dream though...
If you're going to stroke an engine, you should go with a known builder who specializes in VQ35s... Boring it will thin the walls, which is why it's pretty imperative to sleeve them to add the strength back. It's almost cheaper to buy a shortblock and build from that, and part out/sell your original engine after the new one is installed!
I believe SFR sells both long and shortblocks for Altimas. If you throw on their turbo kit for our A/Cs and want to build from there, you might as well get your engine stroked out since you would need to build up the internals anyways.
