i'm addicted to revs..... i want to max out my rev on my coupe!


thinking about getting
Nissan VQ35 CNC Ported Big Valve Cylinder Heads (KK3671)
Nissan VQ35 High Performance Short Block 3.5L High Compression (KK3879)
280degree Tomei cams


I'm wondering if this will max out my redline to 10.5k!!!!!!
By the time you buy all this, install it, and make it run right, you could have bought a factory crate VQ35HR, and put a TT kit on it.

10,500 rpms is high!! making power near that high is going to be the hardest part. i had my fully built all motor GSR rev at 10,000,, course it made power to about 9,300rpms.

I visualize two inline 3s after a stock block VQ35 spins to 10,500rpms. I could be wrong though, give it a shot. Figure it will take about $20K in the motor and drivetrain alone to pull all this off.

yeah i know theres alotta work to be done to reach 10.5krpm but i'm good if its even at 8k or 9k rpm.

yea i know. that's the next step that i'm trying to figure out. its like the WRX, i heard that top end really sucks.

how many members do you see around here with a F/I setup?? ALOT! i thought i ween myself from being in that "group." I'm mainly an N/A guy either way. thats why i want them higher revs.


i guess a cosworth plenum + cosworth headers + cosworth high compression short block and tomei 280 cams as well as tomei headers will do.

that SHOULD raise my redline. course i need to figure out, "by how much?" it'll be like an s2000 with a v6!! LOL no just kidding

motors can be built to rev high, rly its about the valves, u dont want to float one or bend one. timing is crucial. but making power on high revs is the hard part.

But again... I wanna see it. Just do it (tm Nike check.)
yeah i'm trying to make a plan for my car. I'm just trying to get a more powerful N/A set up with higher revs. That's about it.

Getting up there and making power at those lofty RPM's can be done reliably with the money you are prepared to spend. The real trick is making power up there AND having the car be enjoyable to drive on the street. It's all about balance. Without the precise balance of cam, intake, heads, and most importantly variable cam timing, the car is likely to be a pig from idle to 5K. Unless you only want the thing to be a 1/4 mile car with 8K launches, I don't think your going to like driving it around town too much.

That's why buying a stout factory HR motor and putting quick spooling turbos on it would be the best bang for the buck. You get 7500-8000 RPM capability out of the box AND outrageous torque/power through the powerband. NO N/A setup can give you that without nitrous. The atmosphere just isn't heavy enough to provide enough O2.

Who cares about reving to such high rpm? Just make the motor as powerfull as possible and let the rpm limit take care of itself.

I hope your oil, water pumps and accessories are also up to being able to spin that high.

Hmmmm an engine swap to an Hr would be a pretty kool idea... wonder how hard that would be! but then, trading in my car would be easier...
