Just wondered if anyone ever looked into having vq30 or vq35 cranks lightened and knife edged???? Anyone think this will help or hurt????? Im sure SR20DEN has some input on this subject??

I don't think anyone ever went this far on a maxima. That's why NA performance tops out somewhere in 13-second territory.

Yeah but I'm stock and my only previous cars were a 1989 Oldsmobile Cutlass that went the way of the dodo when some ****ing punk smashed into it with his riced out civic doing 120+ km/h in a 50 zone and a beat up rusted piece of ****, an Automa**** 1989 Mercury Topaz with 315,000 km on the clock and a whopping 98 hp so for an inexperienced stick driver I think 15.0xx is pretty good. Plus my cat looks ready to explode and I've got a Knock Sensor code.

K. But like I said maxima guys would rather supercharge their cars than play with the internals. We're lazy by nature, we bought an already fast car instead of doing like everyone and getting a civic and trying to make it fast with neons and eibach stickers.

I wonder what the difference in weight between the two. I know the VQ35 one is bigger. I know they can take about 1 lb out of a higher power h-series honda engine crank. And that crank is still good for 1000 hp. I am guessing lb and a half outta Vq30 one and a little more outta VQ35 one. You would need an experienced person do do that and get it exactly balanced. If your going N/A you might be able to take more out if you want to rev really high.

I wouldn't be suprised if there was less to take off of a VQ crank than a B Series. Then again I don't know ****.

Actually, the internals of the VQ35DE are supposed to be lighter. The 3.5 doesn't get its extra power only from the 510 cc of extra displacement and Variable Timing Control. The entire engine is supposed to be 35 pounds lighter total than the vq30de.

wrong .some of the vq 35 internals are lighter like the valvtrain but the vq30 pistons and rods are lighter

a guy took apart a 3.5 from his 350z. He said the crank was soo terriably heavy. He said it felt like the crank weighed more than the whole block. I am pretty sure it probally weighs 50-65 lbs. I am probably wrong. The pistons and rods weight less than the Vq35 rods and pistons. The valvetrain may weight less but that is not a big difference in weight. Aftermarket rods and pistons seem to weight the same amount of less.

I am pretty sure most of the power comes from the 510 cc extra displacement.

I said h series but anyway. I was referring too a 4 cylinder engine to a 6 cylinder engine. Comparing 1 pound to 1 1/2 lb. Best think you can do is take it too a place that builds high horsepower engines, show them a crank and ask them how much material do you think can be removed from this crank.
