MK3: HKS Performance Camshafts

[supertoy]

Hello, does anyone know where I can get a pair of HKS performance camshafts for the 7MGE engine, how much should I expect to fork over, and how much horsepower and torque can I expect from it???

thanks ---j---

Very rare. Occasionally come up on ebay.

Expect $1200 used (not kidding)

Until you see high HP numbers from exhausting pretty much every other mod, you get almost nothing. They move the power around through the range, but won't increase it much. Typically only in the domain of large turbo Supras. Toyota did a great job on the stockers for anything less.

1,200 $$$, basically no power and people actually buy those things!!! What mods should I do before purchasing a pair, I've done the basics; headers, test pipe, Flowmasters, and air intake system???


Will going with a 3" exhaust system (from headers-flows) give me more power or back pressure???


What other mods should I do before purchasing the cams (nothing to extreme like increasing compression or port/polishing)???


Did they come out with a bigger throttle body for the MK3 n/a's, if so what kind (brand name/s), where can I find them, and how $$$ much do they run for???



Will a one piece aluminum driveshaft give me more power/torque or is this just a myth???

thanks ---j---

If you aren't running a big turbo, I have yet to really justify it. There are gains, but in the order of 1-3 percent. A complete waste on anything CT-26 based. Open the head up for more power, but you don't want to do that.

That said, a port and polish are required as well to take advantage of the cams to any degree. Bigger cams will outflow the head, as a built head will outflow stock cams. The stock arrangement is surprisingly well designed to work together. Changing cams pretty much requires changes to the head to do much.

MKIII NA has next to ZERO aftermarket. Even the turbos have very little. Throttle bodies do not exist to my knowledge. There is one upgrade for the turbos that bores out the stocker, and of course the turbo A had a larger one, but that's it for us.

Lightweight rotating components do not give HP, they simply don't rob as much. There is a difference. It will rev more freely, and allow more power to be spent on the road than getting the shaft turning. How much...hard to say. Nobody's really tried hard to do one on an NA, or has really posted the results.
