right cams for built 2.3l

[evil tsi]

its time to buy the cams to finish up the motor and like the thread states im looking for the right cams for my setup. all the mods in my profile are up to date. i just got off the phone with two different places and one said they didnt have a clue and another recommended a set of fp2s or kelford 272s. to my knowledge they are 2 completely different cams. the cams i was looking at were the comp 101300s and the 101400s. i plan on revving it out to 7500 and i plan on later upgrading to bigger injectors and e85. the help would be greatly appreciated.

What all is done to the motor? Any head work?

Subbed. Would like to know recommendations.

Iirc the fp3x were made with strokers in mind

I'd vote Kelford 272's if you wanna drive it on the street. I currently run HKS 272's on my 2.3L and will switch to the Kelfords for my next cam.

how streetable do you want the car to be, Im in the same predicament except with my 2.4l and am probably going to go with fp2's. Great cam from what ive read

hey revolution what kind of gains did you see from switching cams on your setup. Or did you always have the 272's in the engine? Just trying to figure out what ill expect power and power band wise before i make the switch

 

[evil tsi]

its a stock head with just crower single coil springs and titanium retainers. id like the car to be streetable and still have the power to turn 11s in the 1/4. i called two more places and one said gsc s2s and another said the 101300s(fp3s)

I'm in the middle of building a 2.3L right now and decided on the GSC S2's. I called a couple places researching and the gist of it was: Cam design is continuously improving, with the S2's being a fairly new redesign. Cams made now are far better than cams made years ago, giving combinations of better spool, better low-end, and better top end. That steered me away from the older grinds such as the HKS 272 or regrinds based off of them.

The cams you have listed are probably all very effective. The biggest deciding factor, I think, will be whether you want your powerband to be higher or lower in the RPM range. I don't think you can go wrong any of them, really. I chose the S2's because they were a good compromise. Doesn't sacrifice too much low-end and doesn't trail off in the top-end. Sounded good enough for me.

I'm running the K280's in my stroker build..

I'm running the fp4's right now and love them. I built my 2.3 as a dd and aiming to run low 10's

 

[evil tsi]

ive decided to go with the gsc s2s

 

[Ppayer38]

I chose fp2's for my 2.3 with Evo 8 16g just because of the range of power and streetablility they have but I think the fp3 or gsc s2 would be a good cam for you as it is inbetween the kelford272 and fp2

I have the S2 cams in my build. I have not drove the car yet but it does have some idle time. Let me say these cams sound beautiful. They resonate power. I would post a video but all i have is mt cell and it does not do a good job of capturing the sound. On a more technical note. At 650-750 rpm i get 7-8hg vacuum and at 950 i get 10-12. They will idle well all the way down to 650 fairly well.

 

[evil tsi]

could i get away with running single coil crowers, manley or supertechs? and stock retainers

I currently have FP 3x cams and will be dumping them soon for some GSC s3 cams.

 

[ed1380]

how are they better than the fp3x?

 

[phunny]

The cam didn't break due to failure, it broke during a botched install.

"I've never seen a thread blow up like this has for no reason at all... this engine has never run. it wasnt a faulty camshaft it wasn't a mivec engine. It is simply tightning down the cam caps with the cam rotated incorrectly. like i said in my first post its a common problem on longer camshafts and it does happen. Heck As many camshafts as i handle i've actually done this same thing with a 2JZ cams before."

And the customer service was fantastic considering it was installer error.

I am running custom grind GSC S2-"R" cams in my 10:1 2.4 and so far I am very happy with them. They have the same lift as the S3 at 11.7mm but with less duration so the lobe profile is more aggressive.

It idles well, driveability/midrange is good, and pulls hard past 8000rpm. Now that everything is back together I hope to get it on the dyno/track soon.

Got Brian crowder 272s you can't tell a difference when correctly idling.
