Can't decide on which cam combo to go with.

[streetdsmpwr]

Here is my setup:
Injen Intake
ETS Street 7" FMIC
1G BOV
Hallman Pro Rx MBC
FIC 750 cc injectors
Aeromotive A1000 FPR
Walbro 255 hp
Megan Racing Turbo-back exhaust

Going to be put in before cams:
Megan Racing O2 Housing
Ported Evo III Exhaust Manifold
Ported Evo III Big 16G

Just a little info on the setup; This is a street driven daily driver, so I do not want to go with a 272 style duration cam for my intake. I do not plan on revving past 7000 rpm since the 16G does not have much to offer after that. I want my cam setup to be fit for my 16G, and I do not plan on going bigger than that. I also plan on sticking with the stock intake manifold. I've been interested in the FP cams, especially the 1x. The FP 1x's seem like a really good fit for my setup, and I do plan on buying some Manley springs. I'm not sure if I should go with a 1x/1x (264/264) setup or a 1x/2 (264/272) combo. One of my friends told me a 272 duration cam on the exhaust side would help my turbo spool quicker. I'm also open to any other cam brand. Any input is much appreciated.

get regrinds and go with stright 272's the hks copies. a friend of mine got these and they are great. also i dont see anything listed for fuel control do you have an safc or dsmlink?

he has done some of the dyno runs, so you may find it helpful

the 272 cams may not be to large for what you want .. depending on what 272 you choose....

also i presonally like the Web 546/547

I have a flash-able ECU which I flashed with a keydiver base re-flash and fine- tuned myself with ECUFlash.

I have glanced at that thread before. It just doesn't seem like a 272 cam can help me when I'm only going to rev to 7000 and I have a stock 2G intake manifold and head. It's my daily driver and I don't want to give up too much low end.

Don't write off 272's, they make good power and when set up properly with the correct supporting components they can be reliable. The right springs, valve heights and proper valvetrain geometry are crucial for longevity and quiet operation. It's not as easy as just swapping them out as many want you to believe. The FP's and Kelfords seem to be the least agressive in terms of ramp rates and don't beat up the valvetrain too bad.

I'm not looking for big peak power, but a very broad power-band good for both street and strip use.

I'll chime in since I am in the same situation with the same turbo. I haven't really seen and posts of cam comparisons with evo 16g's, and there are craploads of people running this turbo. THere is of course the infamous AMS cam comparison, and I have studied it up one side and down the other. AMS Infamous DSM Camshaft test | HKS | Crower| Jun | Web | Eagle Talon | 4g63 Cams But in looking at the graphs, there appears to be very little difference between the 264's and 272's in terms of power or spool at any given rpm. This cannot be right can it? I have a chance at a set of used hks 272's for a crack price but I don't want to lose all my bottom end or waste time and money on something that will never benefit the car. It's never gonna see a S259 or Holset, I'm stuck with the 16G for awhile. As posted above I guess it depends on what 272's you get. If anybody knows of some real world results with a EVO3 and big cam combo I would love to see it, and it would be useful to a lot of people. Is it possible to run a stock intake cam and aftermarket exhaust?

Looking at the AMS test, it looks to me that the 264/272 combo is the best street/strip combination. It had 10 more peak torque than the 272/272, only 1 less whp, and has a better powerband than the 264/264. Looking at the graphs, the 272/272 did have more usable power up top, but I don't want to loose 10 wtq just for a little more top end. I'm trying to decide now whether the go with 264/264 or 264/272, 272/272 are out of the question now.

264/264 or 264/272, 272/272 are out of the question now.

I would go with the 264/272, then 264/264, then 272/272 but the 272s need be a little big for a 16g.
