Looking for CAMS for 2.0L Beta engine, that people are impressed by and have used. Want to stay N/A but need more.

 

On the cheap side, the older 96-98 elantra 1.8 intake cam, $120 DIY install good for 2-4 hp @ the wheels, the newer 2.0 beta II cam from the 2001/02 elantra maybe better but we need to see about idle and long reliability in the older motors. I've heard good things about HVE cams and CAT cams but myslef have never seen them in person.

 

Brendan are you refering to using the Elantra GT intake cam instead of the older 1.8 intake cam?

 

Yes, that is what he is refering to. Red is currently using it in his motor, until he gets his hollow core turbo cams in.

I'll be running it in mine untill I get my hollow core cams in as well.

It will work fine with the stock valve train...however, with the extra .8mm of lift some have expressed concern of the longevity of the HLA's and the Valve springs. I personally do not think the .8mm is significant enough to worry about long term. The HVE cams have more duration and about the same lift. RPW also sells beefier valve springs for those that are worried.

 

I have qualms with the cam because last i heard cams designed for Hydraulic valvetrains are VERY different then mechanical cams. They don't look all that different, and will bolt in, but will cause severe valvetrain wear, and should cause poor idle because of the difference between the begining of the lobes. Of course, this might work perfectly well and just be another weird thing with Hyundai.

 

I'm also the one who posted on FXTreme (as well as here) that the cam styles between hydraulic and solid are radically different and could cause harm.

I have later found that this is true, but only for highly modified camshafts. The problem lies in the "ramp rate", or the speed at which the cam is allowed to ramp up from 0 to 100% of it's lift. In an HLA system, the ramp rate cannot be as fast as a solid-shim system because of possible damage to the oil membranes inside the little lifters.

But on a stock cam, the ramp rate isn't going to be anything like an aftermarket cam. So long are you're just going for the Hyundai stock cam, it isn't going to damage anything. The 2.0L Elantra GT intake is fine to use in the older 2.0L hydraulic lifter heads.

So...would performance cams for the HLA equipped motors then be safe for the Solid Shim motors? It sounds like it from your description.

If so, this would give the new 2001+ elantra folks some cam options.

 

No, performance cams for the old motors will make you car run like crap, and might cause some valvetrain damage.

 

So.. will an elantra GT cam work in a 2000-earlier model Tib?

 

Yes, Red has it in his 1997 Tibby now.
