Support for cams Cams
CLARIFICATION:
ALSO, My particular comments were addressing the possibility of running rich without a tune and ******* down the car.
Lean conditions are a WHOLE different deal. I cautiously watched the injectors as an indication of what the fuel delivery was doing, watching for over 95 percent peaks in the duty cycles.
THERE IS NO SUBSTITUTION FOR A PROPERLY USED WIDE BAND WHEN ACTUALLY TUNING.
I hadnt started tuning yet.

" also u dont need a fuel pump till u get neer 400+hp stock will do fine."
But he will be close to 400 with the mods and the right tune, theoretically. At least he will have the bolt-on mods to support it. The right tune could get him very close.
It's cheap EZ insurance. There were reports of possible lean conditions with the stock pump a year or two ago, don't remember the numbers for certain. Sorry to bring them up again, but the thread I read was by Shiv.

i found a place where to Tune my Ecu ... its not in my country though
in another thread .. i have been told .. i can get the fuel pump .. but i have to tune after the installation .. and i guess that what im gonna do .. install the pump and send my ecu for a tune the next day ...
then my next step begins .. from what u guys are saying in order to get the cams ... i should get the cam gears and the headstuds, valve cover gasket and Injectors ..
then send my ecu again for a tune
^^ correct me if im wrong

Since you're opening the head, I'd go ahead and do the head studs...they are cheap insurance like a fuel pump. Do the valve cover gasket, but not injectors.
Yes:
- cams
- cam gears
- arp head studs
- fuel pump
- valve cover gasket
- flash
No:
- injectors
- head gasket
You should just buy all the parts, then get your ECU flashed for all the mods. Right when theECU comes back, install all the parts, then install the ECU. You don't want to have to flash twice, but if you HAVE to, then get the first flash for all your current mods + fuel pump, then install the pump at the same time as the ECU. Later, when you do cams, get the 2nd flash and install them both at once.

The following is a famous quote, please take it in the best, kindest manner possible:
"those who do not study history are doomed to repeat the mistakes of the past"
Most of the posts told you that headstuds, gaskets and injectors are NOT neccesary.
But buy them if you like. The World's economy can use all the help it can get.
Good Luck, what ever you decide.
I'm outta here

OK WAIT, I'm back for a minute, just saw talon's post.
That all works except:
unless he does the one stud-at-a-time replacement, Isn't it possible that he might introduce the need to actually replace the head gasket if the head lifts in the process?

"but it is not cheap and easy to pull the head off again later just to do the studs."
Warrtalon,
But you still just pull the valve cover to do the studs later (at least doing them one at a time. Going from the description anyway, I haven't tried it though)
I was going to try the one-stud-at-a time method on the studs the last time I swapped cams mostly because of the debate over needing to replace the headgasket because "the head can lift when all the studs are removed". I decided against it though.
But after all is said and done you are correct, good insurance once you start raising the boost, (edit: at that mod level anyway)
