HKS 272/272 or 264/272 Cams?

[Sayajin]

Hey guys. I know that this subject has been touched on before, however there has not really been a post (or one that I found) that directly contrasts either the 272/272 setup or the 264/272 setup. I have heard contrasting things from people on both sides and I wanted to get a comprehensive opinion set up. Also please let me say I don’t want to hear anyone talking about well get 264/264 setups, that is not what I am asking you about. Thanks.

I have read that some people feel that the 264/272 setup is the best. It provides the high end power and you do not compromise the low end power of have to worry about very rough idle. I have also heard that this setup is pointless because by using these cams, it removes the advantages from having the 272 in the first place.

I have also read that the 272/272 setup is the best (remember 264 is not an option!) becuase it provides the greatest power gains available. You lose some low end power and you idle very rough, however the great power gains make it worth it.

What do you guys think? Go with the HKS 264/272 setup? or the HKS 272/272? Thanks a lot guys!

Thanks for posting that link. I am soon going to be getting some cams. That made my decision easy as pie. I'm sure others on this forum will be thanking you for the info too.

Cool, so it seems that the HKS 272/272 setup is the best one.

if you go by the website that was posted your non option 264/264 set up produced the best numbers. i was gonna go 272/272 for my car

 

[heavyD]

264/264 is the best option for most. You have to rev the engine higher than 7000 rpm and have a large turbo to get the most out of the 272's.

 

[Sayajin]

Well I plan to get the FP3065, so I think I could consider that a big turbo?

I have very high (future) power goals which is why the 264 setup is not the best for me.

Based on the review... wouldn't 264/272 be the bes option... just a tad slower to full boost with 1HP and about the same lbs/ft.

Is a 264/272 setup equal in price to 264/264? I have heard that the 264/264 will not have any difference in idle when compared to stock... while the 272/272 is pretty harsh... what should one expect out of the 264/272?

 

[ldstang50]

there's a guy on the evo forums evolutionm.net that has a side bite of his evo running 272s all around there is no lumpiness or bogging in his idle at all. but then again its an evo and im not sure of all the differences between its motor and the eclipses motor

 

[neuralracing]

I have a coworker with an Evo8 and he has 272/272... with HKS springs and Crower retainers and valves... and he had to do quite a bit of tunning the vacuum to get the idle to be "less harsh".

 

[ITSME4G63]

well get 264/264 setup!

 

[Corman12345]

You have to remember that the cam comparison test was done using a small 16g turbo. The gains would have been a lot higher with the 272/272 setup using a large turbo

Mind sharing the facts you're basing that statement off of?

For what it's worth the idle from the HKS 272/272 cams isn't bad, and I can't really tell the difference between the 264/264 combo . It just sounds like a car with, well, cams. Definately very cool.

 

[Corman12345]

All I am saying is the test make the 264/264 combo as good or if not better than the 272/272 and It probably is with the small 16g.. But if you plan on making huge power with a very large turbo (race setup) the 272s will make a difference. You just have to keep that in mind. I am not saying either of the setups are bad, It just depends what you want out of them.

 

[Wipf]

Lets take it back a little bit.. There really isnt anyway for me to tell you what is better for you if I dont know what they are going into.. You have to remember that the cams will only help you if you have the right support for them.. If you are running a small turbo and say man I want some beefy cams that is bad news because all they will do is inhibit you by making you lose torque and honestly not increasing any horsepower because of the range where the cams start making power, is for the most part in the 6500 7000 range if you are running some 272's.. All the cams are good but different ones compliment different set ups better.. Hit me back with what your set up is and I will give you my opinion..
Take it easy..

I have hks 264 and 272, but they are not installed yet. I was wondering I have my 2.0 block bored out to .030 over and all new valves will the new lift of these cams hit the pistons or is it pretty safe?

 

[FASTSPOOLINGST]

No, it shouldn't be a problem. Your bore size has nothing to do with the vertical placement of the piston in relation to the valves when the pistons are at TDC. And having new valves in your head will not affect anything either. If you had your block and head decked, which you should have if it is a rebuild, you my want to go with a thicker then stock head gasket to compensate, to be sure your pistons will not hit the those pretty new valves u just put in.

 

[Darktalon92]

Here is what I think. 264/264 is best for all turbos from 18g and smaller, 272/272 is best for 20g, 50trim and up.

I have an 18g with the 264 combo and its perfect for me, my friend with a 50trim has best results with the 272 combo.
So to answer your question which is better I would say 272/272 is you have a big enough turbo.

 

[neuralracing]

Dam... i always come back to the Dilema of what I should do as far as the turbo upgrade... it all boils down to that. I want something that spools very very quick but at the same time has a good top end... I first thought of the B16G... but I think I will fall short on what I want and I hate to buy one thing to then have to sell it for pennies on the dollar and buy the next. I want to get things only once... So it looks like the 272/272 might be the way to go for me now... just wondering how I will handle the idle issue being that I do not have a stand alone yet.

 

[Darktalon92]

The idle is not that bad, just a little bad from a cold start.

 

[Boosted98gsx]

Or if you're plannin on gettin a monster turbo, just call up hks and get a 274/274 grind

(And yes it does exist)

 

[out there]

Or if you're plannin on gettin a monster turbo, just call up hks and get a 274/274 grind

where did you find out about that?

 

[Boosted98gsx]

one of my friends used to work for tchargers.com, and he bought those grinds.

 

[Sayajin]

Well here is what my tennitive setup will be. I am actually doing a lot of upgrades all at one time so it will get there somewhat quickly.

Im looking for about 550WHP or so. I am currently running a Busher Stage 3 Shortblock

HKS Cams 272/272?
FP3065
750-850CC Injectors
Supra Fuel Pump
EVO Manifold
GM MAF
all supporting stuff...

I am actually redoing my entire fuel system and what not. I just wanted to put my basic setup here since someone asked becuase it would better allow them to answer my question about 272/264. It seems that with the turbo I am getting however, the 272 would be the better option.

[stangtt]

Most definitely go with 272's with a FP3065.
