I am looking from input from tuners along with guys that have been on both sides of the coin.

Alot of guys out there run either GSR cams or ITR cams when sticking with something OEM. Aftermarket comes to Pro1s, 2, Tuner1 etc. I have seen where guys are not happy with numbers produced from a Turbo spec cam and I am unsure as to why that is?

Me personally, I am looking for 400 with my LS-V:

b16 head w/ p&p
full crower valvetrain
old style S2 intake mani
750s

b1 block
eagle rods
je 9.1:1 pistons

Garrett t3/t04e 60/63 turbo
Peakboost FTW manifold setup
Tial 38mm gate

s300

To me, this seems like a pretty "common" setup for guys who are not going extreme. With setups like this, which cam choice would be beneficial? Why is it that turbo cams do not make the numbers they should or why do they fall short and not liked?

Also, from an OEM or Aftermarket NA cam setup, which way would you guys go?

Just alot floating out there and I would like to hear input from various people and tuners as to what they have used, seen, and experienced with cam experimentation.

TIA guys!

You are correct, trying to start a discussion here.

Thanks for the input for my build although I would like to have a discussion about this.

Why do people not see the numbers from the use of turbo cams? Whats the advantage of NA cams? How can the Bisi 1.2 turbo cams pull 30+ over the ITR cams on a FI setup but no other company can seem to perform with their turbo cams?

I was told by T1 that R cams will make the most power on a small setup like mine or yours.

When something from the factory was designed NA, it seems to be NA. When it is a turbo factory car, turbo cams seem to work a bit more efficiently.

I think it has alot to do with flow, as we all know VTEC heads flow great right out of the box, people with factory turbo setups need to add those turbo cams just to get to where we are stock, and none of them can carry power like we can at very high rpm without extensive headwork and all the other supporting mods.

It also seems that the extra overlap associated with NA cams benefits us with increased scavenging, studying boost plots of NA cams on FI setups you will see a gain in HP at less boost using the same boost controller settings which means boost is being pushed out the exhaust but its apparently not affecting anything negatively. I am no expert but this is what I have gathered with the numerous Cam threads recently.

im my boosted crxsi i have sk2 stag1 tunners in my 95 teg i running blox stage 1tunner also . heard good things about both cam in a booosted set up. the itr cams r kool but unless you know how to measure them u can get ripped off .i go both sets of my cams off ebay with the oringnal papers and boxes. for 500 for both sets .its up to you on what cams you wanna run .i guess money and avaiblity is the question

Great help! Im sure he appreciated this response. Thanks for wasting everyone's time moron

Like others said, go with ITR or maybe tuner1s. Pro1s are too aggressive for your set-up

Thank you sir!

Thank all you guys for your input. I have heard all of the above, and seen all of the above, cams used with great success in a small setup like mine.

I also like the fact that you guys turned from my setup to cam talk in general. Thats what I was looking for.

As you all can tell, I dont do much posting but Ive been around a while. This thread seems to hit on a debate that I have search for many, many times. The are many sugestions as to why N/A cams seem to be the cam of choice but not many explain why.

This is what I notice, and feel free to correct me if I'm wrong. N/A Cams, Skunk2 Pro's in particular, make great HP numbers. More so than a turbo cam setup. The only problem is that it makes most of the power in the upper RPM rannge due to longer duration. Turbo cams, seem to build HP quicker and maintain a more useable powerband only to fall off at the top due to shorter duration. With that said, can someone expain why?

Great Thread by the way!
