HKS 272's

[Onefast99gsx]

Well i pretty much said f**k it and ordered HKS 272's. I spent about 2 weeks of dicking around trying to find great reviews on about 3 other makes. I guess for the extra $120 or so, it's a good feeling not to think about the research anymore. I spend an incredible amount of time researching stuff.

Question: These are not predrilled and tapped. Does anyone have a how-to for that? I guess like drill size, tap size, how deep, etc.. Also what's the best way to center it? Does everyone do it in a lathe and horizontally drill it.

Thanks for the help!

Why aren't they? I've never even heard of that. Doesn't sound like something I'd want to do to such an important and expensive part, but good luck.

They don't come drilled for 97-99s from HKS.

Take the CAS bolt and the intake cam to a machine shop, they should be able to do it for you.

That makes sense. I thought he was refering to the cam gear holes. That'd be pretty retarded to sell somebody a pair of HKS 272 cams without that.

Would it be easier to switch to a 95-96 CAS? Although I suppose the 97-99 head is missing holes for the sensor?

If you can't find a machine shop I'd try HeadWerks in Bloomington.

Are those the "best" performing cams for the motor (4g63-T)? I've heard others but same problem with which cams are the "best" or good ones.

I don't exactly remember the thread size and pitch, but as ecoli said, just match the drill bit and tap to the CAS bolt.

I drilled mine and it will make you very nervous, one slip and OH OH,......

Oh, and good choice on the cam selection. :D

Thanks 1ViciousGSX & CDeutsch. I think i found something on dsmtalk about the bit size, depth, etc.. I will verify. My brother is a professional machinist. He's the one that would be doing the work.

I thought so to on the choice selection. You may know that i've been asking about cam selection on here for about a month now. I almost bought the FP2's but so many people saying they're buying them and that they'll post a review and then you don't hear shit from them. They were $595 shipped. I got them from ExtremePSI. They still have more 272 combos on the shelf. So with the 272's, PTE 50trim, 780cc, Magnus, DSMLink, Fidanza, etc, that i all have, this car should rock at the track. I predict about the 2nd week of May before it's all done. Silver 2g GSX, with 19" RH C5's, wrapped in Parada Spec2's. I just can't wait to take it out.

Thanks again!

Sweet! Good luck with the build. The 272's were a good choice! They're consistenly the only ones I've heard of that don't seem to need adjustable cam gears. Not to mention the results are equally as consistent.

I look forward to see your car in person.

Bah, you can't make power on those cams. :)
