fastisnice Posted March 9, 2004 Share Posted March 9, 2004 Basically i want to get HKS cams from Gaz and i want to know which profile 264? 272? whats best suited for my car? im aiming for very high BHP outputs...anything from 750-800 to 950 (with NOS). I still want my car to be drivable, i heard that if you go too wild it can mess up your idle? is that right? thanks Quote Link to comment Share on other sites More sharing options...
eyefi Posted March 9, 2004 Share Posted March 9, 2004 best to get yr engine builder to spec em. longer duration means choppier idle, higher lift is shorter spring life. high lift & long duration give a peaky power band, low lift and short duration give broader power bands. there r loads of considerations. its all about trade offs and optimization.

Guest Terry S Posted March 9, 2004 Share Posted March 9, 2004 264 intake, 272 exhaust Quote Link to comment Share on other sites More sharing options...
Syed Shah Posted March 9, 2004 Share Posted March 9, 2004 Yep, go for staggered cams, 264 and 272. Supposedly more suited to the 2JZ than using the same intake and exhaust cam duration i.e 272/272. There is an article on this on http://www.mkiv.com or http://www.to4r.com , can't remember which. What turbo you going for? Quote Link to comment Share on other sites More sharing options...
dude Posted March 9, 2004 Share Posted March 9, 2004 Some say stagger em some say not , check out this spec and make your own mind up , and look at the ET BTW my slicks are here so if you want those DR's let me know before i keep using em and wearing em out !!!

Wez Posted March 9, 2004 Share Posted March 9, 2004 Some say stagger the profiles but the cars I have seen with the same profile on inlet and outlet are performing very well for example Nicolas Kias has 272 / 272, there are a couple of cars running 264 / 264 which go well. I am in the same boat at the moment and can`t decide between 264 / 264 or 272 / 272. If I go for 264 / 264 I will loose a little on top end but my midrange torque should be better and visa versa on the 272 / 272 setup.

If you go the HKS ite and look at the power graphs the 264's look the best bet by far and they stay non interference !!!!

MONKEYmark Posted March 9, 2004 Share Posted March 9, 2004 i went with hks 264/264 and no problems was advised to go with 256 but thought i would take a chance on 264`s was a bit wary of the 272`s as it would mean a lumpy idle and loss of bottom end power. read they were mainly for big power cars. have a look at this horsepower freaks supra with aem ecu with 850 hp at the wheels, it has 272/272 cams and idle is great. they have set it to 1350 rpm tick over http://www.horsepowerfreaks.com/videos/HorsepowerFreaksAEMDemo.wmv thought you was ordering in your own parts to save money?

Wez Posted March 9, 2004 Share Posted March 9, 2004 Looking through this page http://www.moreboost.org/cams.htm its only the JUN and Crower that turn it into an interference engine as they have more than 10mm lift. I think the 272 / 272 will over more top end power but I think I would prefer the midrange torque from the 264 / 264, this is also my daily driver so i don`t wanna have to rev the nuts off it all the time. Is there anyone with 272 / 272 combo who can comment on how it drives or even better who has a dyno sheet they can share. Quote Link to comment Share on other sites More sharing options...

Who told you that , the 264's are only just non interference on stock settings , using vernier gears puts you at risk of becoming interference !!!

According to that there is a .65mm safety margin , IF the head hasnt been skimed !!!!, everyone i speak to says treat the 272's as interference and thats good enough for me , if the car in my first post can run 10.05's on 264's why go any more !!!! , the 272's will defo give a shit idle !!

Syed Shah Posted March 9, 2004 Share Posted March 9, 2004 He is making that time with comparitively little power. He takes his drag racing very seriously and the car is setup for it. Those of use who wish to run those times without turning our cars into straight-line only machines require more power. Hence larger turbos and 272s etc. Quote Link to comment Share on other sites More sharing options...

Syed Shah Posted March 9, 2004 Share Posted March 9, 2004 That is one of the many points we differ on mate. I prefer a proper suspension setup for corners, and a load of HP to do the 1/4. Rather than suspension/tires/gearbox more suited to straights rather than corners. Not a hardcore drag car (Dave H on SF for example, and the shop cars), but still not exactly suited to corners etc. Quote Link to comment Share on other sites More sharing options...
dude Posted March 9, 2004 Share Posted March 9, 2004 Did you not see Migs link to the HKS coilover suspension , with that and a pair of stock wheels with DR's thats all you need to run 10's with under 600hp so why have a wild engine and big turbo that are no good in the twisties where you want instant power and loads of torque not masses of lag and top end power , i dont understand , that car in my link with 18's and radials and the settings changed on his coilovers would be a killer round the bends Dude:flame Dev Quote Link to comment Share on other sites More sharing options...
Syed Shah Posted March 9, 2004 Share Posted March 9, 2004 Depends on your expecations in corners, a proper suspension setup for corners needs more than coilovers. Also, IMHO autos and corners don't mix (but we should leave that to differing opinions before I start a manual v auto flame war). A single turbo can be changed much faster than a transmission/suspension setup as well. So you can have a smaller turbo for twisties. Finally, I CHALLENGE you to run times like his with that sort of power, bet you won't and hope you do. Quote Link to comment Share on other sites More sharing options...

Guest Terry S Posted March 10, 2004 Share Posted March 10, 2004 The reason staggered cams are suggested is the design of the head. Correct me if I am wrong gentlemen but do JDM cars not have staggered cams from the factory...........If so do you think Mr Toyota did this for fun? There is no issue running the same profile, just it would appear certain experts agree staggered is more suitable to the head design.

Wez Posted March 10, 2004 Share Posted March 10, 2004 Hello Terry, Its very true that the JDM are staggered and by 9deg but the US / UK spec is only staggered by 3deg and uses the same head design as far as i am aware. This may have been due to the difference in turbos. Quote Link to comment Share on other sites More sharing options...
