TheNeedForZ

Greetings, I have a question about using a 4WD 4L60E (from a 2004 GMC Sierra) in a 2WD application (my engine is a 98 Camaro LS1, Car is a 260Z). Is the 4L60E used in the 4WD application (trucks) basically the same as the 4L60E used in 2WD application? or are they totally different animals ? I do understand that they share the same bolt pattern, I am not sure if that's where the similarity ends, but I hope I can use the 4WD auto trans in a 2WD application without too much modification.

It does look very clean/decent. But the 5000$ Portland deal is very appealing.

Aluminum retainers are available from Nissan Motorsports, but is only slightly lighter than the steel ones according to the how to modify book. Titanium is also mentioned but is not considered cost-effective. I think the most effective valvetrain weight reduction start at the valves themselves since there is a chained effect. A lighter(titanium) valve require less spring force to control, meaning a weaker(lighter) spring is allowed. Weaker springs will allow lighter(weaker) retainers and rocker arms.

Interesting info on the emissivity test. Was the test done on emissivity alone or did the entire heat flow increase overall? With a radiator, I believe a bigger portion of heat is conducted away thru contact with air. If you put your hand near the radiator you will feel the heat but if you touch the radiator it'll be very hot. If the anodize coating promote heat radiation without hurting any contact transfer I'd say go for it.

really? you sure you didn't just miss the three casting letters and think the KEW ones are modified pieces? ...I kid, I kid. Anyway, you can take off material here or there but what Kameari shows is how modifying stock piece to 60g results in breakage in the strength test. In contrast, the 57g KEW pieces are lighter and passed the strength test. That's how they boast superiority, but it's their ad... *cough*titanium valves*cough*

I don't think those are modified stock pieces. There are three cast letters on the side of the rocker (looks like "KEW" = Kameari Engine Works?) that are not found on stock pieces. Those letters are above the surface reather than under the surface so the letters are not carved. I would bet they are new pieces. There is only one way to know for sure how they did it...you order some...and then let us know

Anodized coating have thermal insulation property, not something you want on a heat exchanger. Fresh aluminum surface will have a very thin layer of oxide after exposed to oxygen, but anodized layer is much thicker.

Who would be dumb enough to use sand? I always use thinned-down concrete in my engine-suck-porting job. That way after the porting is finished, all the ports will have a ceramic coating. BOING!

That solved a small mystery for me. In the Wangan Midnight PS2 trailer there is a glimpse of a flywheel with 7 bolt holes instead of the usual 6. Always wondered about that flywheel. http://video.google.ca/videoplay?docid=3353582178439412350&q=wangan+midnight+ps2&total=23&start=0&num=10&so=0&type=search&plindex=3 That's a video of the trailer I am talking about. You can catch a glimpse of the 7 bolt hole flywheel at around 1:21

you mean ITB as in Independent TromBone? http://en.wikipedia.org/wiki/Variable_Length_Intake_Manifold IIRC there are systems that switch between two lengths of runners like Paul mentioned. There is also a type of system that connect/disconnect two plenums to create different amount of total plenum volume.

It's even fast in the reverse. good job.
