HKS 280's

So someone i know is selling these HKS 280's, will it give me unstable idle or will i be fine w/ them? I was going to go w/ the GSC 272's but he's offering me a pretty good deal on the 280's. I want to know if the 280's will be to aggressive for my daily driver. What do you guys think?

280s will be very lopey, but I don't consider it "unstable." They are typically too much for a normal daily driver, especially on the stock turbo, because they excel at high rpm where the stock turbo falters. They still can work fine, though, if you are getting a great deal, but that better mean you're getting them for less than $400, otherwise it's not any better than the GSCs.

They appear to be working the best so far in terms of reliability and power.

Yup should be under 400 for sure, but should i grab the Fidanza cam gears too or are they unnecessary?

Not normally necessary, but you may want them with 280s in order to dial in the powerband optimally. If you don't know what settings to use, though, then don't bother. They do nothing when installed and set to 0/0.

Yup, I reaserched for a long time befor getting the adjustable cam gears with my HKS 272's and when I move up to a high lift cam with no cam gear data available I will be putting the stock cam gears back on the car.

Fourdoor, how well do 272 cams (HKS) run on a stock VIII? I just have an intake and 3" turboback. Just want more torque in pre-boost and on-boost, stuff horsepower

They are not going to help in the "pre-boost" area of your power curve, more in the mid to upper RPM range.

If you're wanting torque start spraying a 35-50 shot at 3500 rpm. Then enjoy the rest of the results on up to 7k-7.2k rpm.

Nope, Nope, Nope, and Nope.

Cams are not for low end torque production.

If you want a bump in low end torque you need a displacment increase (2.3 liter, 2.4 liter etc) or you need to go to a smaller than stock turbocharger that will spool up earlier in the power band.

You may be one of those people that would be truley happier with a Camaro or Mustang.

Not really. Drove them and personally am not impressed. Won't say any more than that

Have ordered a set of HKS272 cams. Will see how they run on a mail-in flash from Jestr since there are no custom tuners in the UAE.

Well, the HKS 272s will definitely work well, but they don't work better than other cams that cost $100 less. Any 272 will be good in terms of overall power, especially up top, but they won't meet your need of low-end and pre-boost torque. I think once you have them in with a retune, you'll be pleased, though.

Roger that. I'm getting them at a good price from an old friend. HKS 272 cams only, no retainers, no springs, no cam gears.

Warr, I've been reading up on the cam gears and have been told they help increase the overlap. However, in the absence of a custom tuners here, I'm wondering if it would be a good idea to get the cam gears unless Al is able to help me with the cam gear settings and the tune. Can you check and let me know?
