264 or 272?

[nogospyder]

I am in the middle of building a 2g head and i am planning on getting hks cams but don't know wheather to get the 264 272 or a combination of the two? I already have crower springs and 1mm os valves.

 

[bTIDDY]

what are your goals with the car. Also if you are making alot of top end meaning big turbocharger than go with the 272's now if your running 16g size or so i would stay with 264's

 

[nogospyder]

I'm running a ported small 16g right now but as soon as I can finish the head I plan to put in a t3/t4. I would like to end up between 350 to 400hp.

i would go with 264/272

I would believe 264/264 combo would make that kinda power, I would say whether your going for top end with great low end(broad powerband) get 264/264. But if your going for better top end with low end loss get 264/272 exhaust. If you want a motorthat cams a bit and is only happy with half-full throttle get 272/272. Either way you slice it I think any cam choice you make you will reach those numbers and still have great top end.

I would go with the 262/262 HKS cams. The 272 is really only needed on track cars running 500+ HP with big turbos. The 272 exhaust wil make the car Idle like shit and street low end sucks untill the turbo starts to spool up around 4k them pulls hard. The little gained from the 272 exhaust is not worth the headakes it gives you on a street car.

Thanks i'm going with the 264/264, but will i still want to have the cams degreed and tuned on a dyno?

 

[ITSME4G63]

I heard the 272/264 combo is good, but this isn't going to be a racecar right? You drive this car everyday, I would stick to 264's.

 

[greathuskie]

RRE doesnt carry the 264 exhaust cam in stock because they think the minimum cam combo someone should do is 264/272 if that tells you anything

thats what i went with as well

FRom the results on this link, the 264/264 gets my vote. I have an auto , so i need the most i can get down low and i'll let the turbo work up top with the tubular 02 3'dp and 3' catback, oh and extremely ported head, with a custom ss tubular exhuast manifold.
264/264 = Spoolup is same as stock and off boost was as good as stock or better
Compare that to the 264/272 = the torque is the same and only 1hp more. The 272/272 IMO is not acceptable for street compared to how the 264/264 came out. (272 combo my last choice of all cams for the street)

for daily driving how much difference is there bewtween the 264/264 vs. the 264/272? also how much MPG is lost with them?

That test was only done with a small 16g turbo which does not have a lot of top end anyways. So the top end is not that different between the set ups. It would be nice if they did a test with a larger turbo to see if the 264/272 and 272/272 combos fair better.

Also the link says that the there was a boost spike :

"The boost level was set to 19psi, but as the turbo came on boost it would spike to roughly 23psi and then fall off to 19psi as the RPM's climbed. This boost spike can be seen by looking at the torque curves. "

This will be more evident with the 264 cams and may have spiked higher with them causing the low end numbers to be higher.

if you definetly plan on upgrading to a t3/t4 turbo as you said, then i would go with 264I/272E even though your currently running a 16G....the 264/272 cams would run just as well as 264/264 and more importantly your car will already be setup for t3/t4 future upgrade. less time and $$ you'll have to spend on your car down the road. why even bother going through the work twice?

however, if you change your mind and stick with a 16G then stay with a 264/264. not sure why some of you are opposed to the 264/272 setup. regardless they are a good combo for a street car.

 

[95TalonTuner]

i would go with 264/272

please dont reccommend cams for someone's setup that you know nothing about.

original poster: the answer to your question is fully dependant on your turbo. you saying t3/t4 tells us nothing more than that youve seen 2f2f alot (not a rip ). saying t3/t4 is like someone asking what kind of car you have and you saying "blue".

please be a little bit more specific and im sure we can help you with a proper answer.

Thanks i'm going with the 264/264...

Good choice. I think they are the better choice for any 2.0L who will rev till ~8000 rpm. 272's are better for BIG turbo, and engine that will rev at HIGH rpm and get others supporting mods like Intake Manifold.

A local guy ran low 11s @ 132 mph with FP Green and HKS 262's

Everyone knows 132 mph is enough to enter 10s. So I guess these are good cams

But keep in mind you always need to "balance" your setup. Some guys ran 10s with 1G stock cams, and others guys ran 13s with HKS 272's.

 

[TSIfreek]

Cams are one of the last places when building power. The turbo you choose is 75% of your HP goals the cams are there to bring it all together unless its an all out race car but how many of us have a dedicated ''race'' car? Very few.
For a street strip car that runs low 12.s high 11s the 262 combo is just easyer to tune and will pass emisions when the times comes.
HKS cams are simple 262- street/strip both intake and exhaust
272- all out 9000RPM race motor that sees little street
If you think you need 272 on the street put them in and find out the hard way by having to put smaller cams in because the low rpm torque on the street sucks.

I've been running the HKS 264/272 combo for awhile now with my FP ported Big28, and I absolutely love them. The car idles a little lumpy, but what car doesn't idle a little lumpy with a set of cams, and besides if you don't like the lumpy idle which IMO sounds awesome, you don't need to be involved in this type of hobby. Anyways... I went with the 264/272 combo because I needed a little more topend with the Big28, in which the 264/272 combo helped tremendously, and if I decide to go to a bigger turbo on down the road the 264/272 combo will work just fine with a FP Green or 50 trim variant. IMO I would go with the best of both worlds 264/272. Just my 2 cents worth

hmm. you might want to check his post. yeah, i believe he did ask us a question. therefore any logical person would have provided some input. btw just in case it wasn't clear to you the first time, he asked a question and questions get answers.

so how about you help the guy out and giving him an answer instead asking a few other questions and trying to slam others in the process. i guess you prefer to come off like you know so much. 'uh, so many variations of t3/t4' WOW einstien...there's a real brainbuster.

the point i was trying to make is that if he planned on upgrading to a bigger (t3/t4) turbo he would be better off with a set of 264/272's. at the end its his choice, none of us will be twisting his arm. wait, i take that back you seem like that kinda guy.

ok, fine. just give him bullshit answers.

EXACTLY! so shut your face.

how in the world can you suggest 64/72 without knowing what turbo hes going to run. that was the enitre point of my post. even above you clearly state that there's "us, so many variations of the t3/t4".

its like im talking to myself. good ole tuners doing it again!

 

[KeltonDSMer]

I'm with 95 on this one. Saying "I have a t3/t4" does not mean anything. It is like asking someone what kind of shoes they have and them saying "white ones"; or asking a honda boy what he's done to his car and getting "stage three" in response.

A 46trim compressor (frank I) in a TO4B and a 69trim turbine with a small A/R t-housing is a lot different than a 56trim monster in a TS04 with the T350 turbine and a large A/R t-housing. Saying t3/t4 is like saying "I have a MHI turbo"---it could be as small as a 9b or as large as a 25G and no one would know.

I don't see why people argue so much; we don't even really know what this guy wants out of his car.

i'm sensing too much hostility, why don't you try squeezing one out...maybe you should get your boyfriend to help you out....and afterwards pop a prozac. you might feel better.

if he plans on going bigger then a 16G I would go with 264/272 setup. obviously his t3/t4 would have to be bigger then a 16G.

you clearly have nothing to add to this converstation. maybe you should head over to the hangout so you can shoot the shit and never get technical. this is the second cam thread in two days that you tried to call me out on. please, rather than calling me a f43g, correct me. id love for you to do that.

Agreed.

FWIW, I've had no problems with the 272 Exh. Cam. Then again, I know how to time an engine.
