Re: CAMS
Sorry, what I meant by "internals" I meant everything that supports the new cams due to the higher lift and increased duration. If you are going that far into the engine, I would suggest working on everything at the same time,...complete engine rebuild. Heads, cams, valves, rods, pistons, flywheel, clutch, and anything else that you were planning to do. Makes the labor cost a little lower vs. having to take it apart everytime. Then again, if you can do this on your alone then,............................ just ignore me. :-)

Re: CAMS
To start with, it is really pointless getting cams if you don't have an ECU to raise the rev limiter. When I dynoed my car stock, my power wasn't dropping off at the limiter. Even stock, it could probably used another 4-500 rpms. For cams, it should need another 1000 rpms. I can't respond about the 260 cams, but I have a set of the JWT 264 cams with JWT single springs in my Maxima. We've done a lot of ECU tuning to get them to run right. There were initially a lot of driveability issues with the car not wanting to start and stalling whenever lifting off throttle. There are very lopey. Think about what a Mustang is like with a 292 cam. You can definitely hear and feel the lope. I have Place Racing solid engine mounts in the car and at the 950 rpm idle the car rocks back and forth. This is a built motor with head porting, port matching, a ported variable intake, ported exhaust manifolds and a healthy set of 8.9:1 pistons to handle a good amount of boost. NA, it has no pull below 3500 rpms. There is a very noticable loss in low end power. At 3500 rpms to 5000 rpms, it feels like a normal Maxima with good smooth torque. At 5000 rpms, it hits cam hard. The car pulls extremely hard from there to my 7600 rpm limiter. It actually feels very similar to the car was when it had a stock motor with a supercharger running 6.5 lbs of boost. If often unloads the 245 tires from the aggressive torque ramp-up. Despite the low compression, it will easily outpull any NA Maxima and in fact runs door to door with a Z track model. [img]/w3timages/icons/wink.gif[/img] I don't know the power mix from the porting and the cams, but all the work adds 60 hp to the wheels on my car and keep in mind that I am still losing at least 10% in power from the drop in compression from stock. From my discussions with Jim, they did the 260 cam for better driveability and emissions, so they should make less power.
