I have read every thread there could be on HKS camshafts, here and on the UK board. It was tough I really wanted to go 272's, but man with all the crying about needing cam gears, then others saying you don't....then you got the know it all that don't even have cams but are telling you what the perfect set ups are,
I really like it when the idle is lopey, make the car have hair on its *****.
On stock turbo 264 seems to make more torque than the 272 and power overall.


Bought my simple 264's which should pull strong enough from the bottom end and hopefully till redline 7000-7500....bought it from PURE TUNING.

Aaron at PURE TUNING has all kinds on camshafts, he actually was offereing me
his TOMEI 260 with 11.0 lift pair for 4 bill with less than 500 miles........dang thats a deal, don't have the money for valve springs......he even has custom billet grinds for any duration your are looking for.

I really wanted 272, with all this bs engine stalling, check engine light, not to mention plugs fouling, I know Jose down at Dynamic turbo is has 2 pairs in stock.....most shops online store don't have it because they are back ordered.

 

if you get a reputable tune done like dynoflash you wont have to worry about stalling or throwing any codes.

 

What kind of racing do you do?

If you autocross you'd probably want the 264s. If you drag race or road race you probably want 272s.

If you sort through all the crap in the forum.....the bottom line comes down to the fact that most people want the additional top end pull that the 272s have.

The people that have upgraded from 264s to 272s say there is a noticable difference in top end and next to no difference down low. When racing how often are you below 3k anyway?

Going with 272s allow you to grow your car whether it be with race gas, alchy, more boost or bigger turbo.

If you get cam gears you can tune 272s to run however you want them to. If you like lope change the gears to -3/-3. If you like solid idle change them to -4/-1. Its not like its one or the other you can tune the car to run better up top or down low. I think cam gears are worth the money because you can get what you want when you want it and probably get more of it as well.

 

why don't you go with 264intake/272 exhaust.. won't you get best of both worlds??

 

i myself just ordered 272's and can't wait to see what happens when they're on, i've heard of all the problems people used to have with the 272's and i also heard the al had a breakthrough flash for em and that everything ran nearly stock... it is the reason i went with the 272's. Like stated above, you don't race unde 3k-3500 rpms anyways, atleast i don't

 

Hey I'm new to this site as well.. And just as curious to know which setup would be best 264i/272ex as apposed to the 272/272. I'm into drag racing as well and would not want to sacrifice the capability of a circuit race. What set up do you suggest i use?

 

There is no reason to go with a 264/272 combo of any kind.

If you are spending the money on cams for racing then get 272s. If you just want a little more grunt but have to have a like stock idling car then go with 264s but I feel that is a waste and odds are two weeks after you get them you will feel the same way.

Almost everyone that has upgraded from 264s to 272s recommend going with 272s right from the start. If you are worried about idle quality just get cam gears and set them -4/-1. You can find a set of used cam gears for $150 which is well worth it considering you can adjust your powerband to suit your needs.

 

Hey I just had HKS 272s installed today at Turbotrix. Yes the idle is lopey,but the top end rush is amazing!!!!!!!!!!!!!!!!!!!348 whp by the way,stock turbo,bov,on 93 pump@21psi

 

I did 272 I and 264E....sounds strange ?? Well If you reserch the stock cams in the car, the exhaust is smaller then the intake... I found that it keeps the boost up. I road race the car and it has LOADS of mid range TQ and still pulls to 7,500 rpm .... Thats what I did... good luck

 

Whos that guy........

 

+1

 

Thanks for all the great input, keep it coming. I would like to hear from anyone using 264/264 your opinion, does it suck? noticable power across the powerband? where does it feel like the power drops.

Don't get me wrong, I would wanted to have straight 272 on the car, but mixed answers of needing cam gears, and some said I did not need them. I just wanted to keep the OE gears....not having to retard cam timing. I agree off a roll your way past the 3k mark, but how often do you spend time at redline?

I was talking to a very good friend who works at HKS today, said the 264/264 will have usable power across the power band, not just mid and top end. He did say that you will see a difference on the 272/272 up top, but 264 will pull strong bottom to top end also, but how much more pulling power does the 272 pull vs 264 is it night and day.....2 car lenghts?

Well, I will see how it performs, I don't drag race the car......I still want the have response down low thats why I went this route....I like to attack the local back roads, more than just all out straight line, because I feel thats where the car shines. I like going flatout but here in VA....but if you get caught your going to jail for a while.

I have heard that the 272/264 set up being used on the 3SGTE engines with great success, and has caught on in the 4G63 crowd.

 

While road racing or drag racing I spend most of my time above 5500 rpm.

Most people tend to quote this test:

However, there is a HUGE difference between a 94 DSM and an 05 EVO. You'll have people telling you that the stock turbo wont make any more power on 272s than on 264s then you have people that have done the swap and notice a major improvement up top.

bottom line with the 272's, is i dyno before and after installing the cams and walked away with 28 more hp and absolutly no loss in power or tourque across the graph, simple tuning was done with an afc on top of a dynoflash, but not tuned by big al, that is without camgears just straight dropped in and adjusting for safe a/f ratio

 

hks 272 / 264 setup is the best.

I go down to 2000 rpm on some of the braking on auto-x, and it's almost like having a supercharger, the power is very immediate and it spools incredibly faster than 264/264 combo of even 272/272 combo.

But there is a bit of power missing up top. That's the only thing.

But this is all usuable power, and you don't have to take it up all the way up to 8000rpm to access it.

I don't care what dyno says, the way the car drives and respond is the much more of how good the car is than some dyno peak numbers that people care so much about.
