However one outlet few people have gone is sleeving the an block and producing excellent numbers but little information on how it was done and how much it was sleeved.

Capecreations21, you were on target about not being understood on a hot rod forum! The smaller, lighter engines in many European vehicles (especially the exotics) push their peak torque and HP way, way out on the curves compared to American Iron V8's. Heck, some of the Ferrari's hit Peak Torque above 9000rpm, and push out to 13,300rpm or higher. Now I'm not saying that your Nissan V6 is going to hit 12,000rpm, but you need to find a shop that works on the tuner crowd's engine needs vs American V-8's. There's a reason you don't take your Ferrari to a Chevy dealership for service, and the same applies to machine shops, IMO.

I hope you'll keep posting your progress on the Nissan V-6, especially a You-Tube video of it cranking out >10,000rpm on the dyno, complete with the graph of power output!

For sure I see where you're coming from.. If a specific shop works machining X American block the steps and procedures could be different than that of X tuner block. I am from cape cod and on the island I think maybe there are 2 machine shops neither one specializing in anything in particular and I think this is the type of job to go to someone who has built high revving motors before like you said.

Everything is currently taken apart and out of the block and the heads are bare but I'm sure it will be several months until I find a shop to build it for me and the money to do so, def will post pics along the way however for sure. Got to keep doing research. There was a post saying that the Infiniti q45 motor has 94mm forged Pistons that you could potentially bore the Nissan block out to fit. Maybe that's an option.
