This is to anyone with good experience with HKS 264/272 cams:

I just purchased the 20g-9 from Buschur. Should be here this week or next week. I already have HKS 264 in/ex cams and was trying to decide if I wanted to go with HKS 272's when I do the 20g-9 turbo. I want a street monster but at the same time I would like it to pull hard up top on the track on straights. Here is the way I am thinking of it:

Because the turbo flows more than the stock turbo, my 264's should be a torque monster with the low end grunt of this turbo. I figured this turbo isn't really a high RPM turbo, so coupled with 264's this turbo should respond better mid range and pull extremely hard? And still have "some" top end left. If I go with 272's I will loose the grunt this turbo can put out coupled with the 264's. Am I wrong on this or should I go with 272's and get the best of both worlds because the low end grunt of the turbo would make up for not having the 264's and then 272's will make up for the less flow the turbo produces on the high end.

Anyone have any good advice?

I am also open to other cam choice but don't want anything any more crazy than the HKS 272's as I drive it on the street around town a good bit.

Any help would be appreciated!
Thanks,
Zach

 

I went with the 272s on my stock 03 turbo and havin't noticed any loss of low end grunt. I think your money would be better spent on something else than a new set of cams. I don't think you'll see much of a difference going from 264s to 272s. Just my opinion.

 

I was thinking the exact same thing....maybe alky/meth injection

 

anyone else think anything....

 

I had the 264's, and then traded them out for 272's. I made the same torque at the same rpm with the 272's as I did with the 264's. The top end above 7000 rpm really opened up though. I didn't make much more peak hp (just a couple), but the hp curve did not fall off like it did with the 264's beyond 7000 rpm. Go with the 272's if you plan on running above 7000 rpm like most flashes allow you to do.

 

272s and meth...

 

since most people vote on 272's, is there difference between comp cam 272 and HKS 272?

 

I guess I have a freak motor, because replaced the 264 exhaust cam with a 272 untuned ecu, and did a fun run with a couple of friends, walked a 272/272. and lost to a 280/280 by half a car, going flatout on 3rd and 4th gear....did 3 runs same results.

 

Dont bother with the 264s, get the straight 272s.
