272/272 cams on stock 7bolt 2g?

[0r1landoDSM]

would i need to upgrade anything such as fuel pump or anything to run 272/272's on completely stock 2g motor with 16g?

 

[goodbuds]

yes there is a few thing's.

Cams should be upgraded later down the road IMO Stock cams should be enough on a stock setup.

Some will argue to upgrade your springs but alot of ppl have ran 272s on completely stock heads with no problems.

I came pretty close.

In my defense, I pulled the stock cams to be submitted for core value and had nothing else to put in the engine. You need a way to tune your low-rpm airflow....just listen to how bad that pig lopes at idle with a 264/272 combo because it's so lean.

It Can be done with a totally stock head. The best combo for a stock head would be the 264/272 setup. I am only running my 272s because I pulled them off the spare part's shelf when one of my cam's measure out of spec on 3/4 lobes.


Mine lope a small a bit at idle. Not quit as bad as Justin's.

you can get away with a stock set up but your idle will suck if you dont have a way of messing with it properly.

INSTEAD.
use that money and get your self some standard copper NGKs they work better with boost.
a manual boost controller. some evo injectors. and SAFC ...youll bake more power than with 272s.

^ Agreed. You can put that money elsewhere, and gain more from it than cams at this point in time. Use the money to get supporting mods for that 16g!

what supporting mods would i need if you dont mind me asking?, i REALLY love the sound of cams

 

[TSITurbo95]

Let me add, its your money, you do as you please. If you go 272 cams, you do not need to upgrade anything, they are drop in cams.

As for supporting mods. . . Fuel pump (Walbro 190/255), injectors (550+), AFPR, ARP's, DSMLink, make sure maintenance is done, etc. List goes on and on.

Others here will fill you in on what supporting mods you need to run the engine.

I will strongly suggest thet the valve springs be checked, yes the cams may run on them, but from what I know and have learned they are in most cases weak from age and use.

and how to have them checked..

As long as you do not run Kelford Cams or clones of them, The BC1100 spring will be just fine and affordabale

Around $90 a set and work well stock retainers

I ran 272s on a stock head with no problems for years the only difference in power is you get a little kick above 6k rpm.

not if you get adjustable cam gears. then you get a nice kick agter 5k to redline. yes you looks some low end but who really ever uses low end aggressively

as for the OP get your self turbo back exhaust, MBC, intake, 1g TB (my personal favorite) and that alone will increase ## top end noticably. from then its like mentioned before up grade fuel system components and tune it. that will get you way farther than cams alone.

but if you want cams then get cams, its your money you car you choice.

what if he used evo 8 or 9 valve springs and retainers instead of stock? I ask becuase I'm going to have my head rebuilt with stock valves but i wanted to upgrade my valve springs and retainers to evo 8 or 9's so i can change my stock cams to FP2's , im in the same boat he is(don't mean to thread jack)

 

[rommel rojasgsx]

are we talking bc 272 or kelford 272

 

[LiquidX]

Bogus and Jack pretty much covered a much needed question.

272 is just a number, it has no relevance to the lift and duration of the cam lobes which is what you need to know to determine if you would need better head parts. Also knowing where your rev limit will be at as well.

For the most part, most 272 branded cams are similar except the Kelford cams. Their 272 is more like a 280-288 cam from other companies since they are much more aggressive.

In all honesty, for a stock motor, just keep the stock cams until you do in fact need to upgrade to a new profile to suite the needs of the turbo.

 

[Mrdocprofessor]

Dude your fine just put them in will you get better performance with. The supporting Mods sure but you don't need them if your motor is all good

 

[AlexSza]

There are a few things to upgrade inside the head, springs for one, maybe valves, I run 272/272 in my turbo conversion 1g. Hard to tell whats stock on my setup but I know for bc and regrinds there are something about washers underneath the lifters to compensate for, I don't quite remember exactly but I did with mine, everything has over 3,000 miles on it, lopes like a drag car at about 700-800 Rpms. Just look at what needs to tolerate the cams within the head, if your going to swap cams I would definetely go with adjustable cam gears,

 

[jrohner]

If you don't even have so much as an upgraded fuel system, there's no point in getting cams. Get a pump, injectors, and something to tune with so you can actually make use of that 16G. You can't even make use of what you have now, so why get cams when you'll just have to run even less boost.
