Then go and get a tune. So i'm looking at $910. Intercooler can be added at a later date if I want to go further. Put in a few of the other things that come up and I should be able to stay close to my $1000 goal (preferably) Seem like a good plan?

The VS cam makes a lot more power than rockers thrugh the entire powerband. You won't feel the gains from rockers until the 4000 rpm range. That's why 105 springs are recommended for rockers, So you can run higher rpm's to reach where the power is.

The VS cam can be ran on stock springs with stock shift points & still make a load of torque. And all hell breaks lose when you stiffen up the springs and run higher RPM's.
But I definately understand the value for the price difference. But don't feed into the BS about rockers making the same power as cams (even a small one) it isn't true.

dont compare a VS and S1X. way different.

You can compare the VS to 1.95 Roller Rockers...

OR...

and XP to an S1X

Or the IS3 to an XPZ

But that's about it.

Yeah I must have read wrong. My bad

I agree except for the VS compared to 1.95 rollers. I'm sorry. I've driven both with similar mods minus exhaust. Not dissing the rockers, just saying the vs cam feels a lot stronger. (especially in the low-mid range). The rockers only seem like a fair match from a 60 roll or higher

Looks like the S1X (+$25) needs the 105# springs (+$50) and a better timing chain (+$80). Costs are over a VS cam. So is it highly recommended to pony up the $155 more? Also this is for a daily driver so that is something else to take into account. More thoughts and opinions?

S1x is overkill if you are trying to get low 13's. If that's your main goal, get the VS cam. If you think you may want to go deep into the 12's in the future, it's gonna be much easier with the 1x. given it's super high powerband

If your goal is strictly low 13's, you should just save the 155 and put it towards something else.

VS cam, 90# springs, headers, 3.2 and tune_ thats an EASY low 13 with good tires if you can drive

What are the supporting mods for a cam? Are headers necessary? Thanks

nothing good lol. blue will say something about his 1.8 60' times on the stock tranny, and he's right. if you're nice to it and don't romp on it around every corner it'll stay in one piece. i've read that you can help it with a tune, program for 4-2 skip shifts and bump up line pressure to make shifts quicker and keep stress off your clutches. DD friendly? eh...

Cams provide a lot of top end power over a stock gtp. Without headers, you won't be taking full advantage of the power up top.

LOL.

Yup.

Shift kits help exponentially on automatics especially with increases in power. With the transmission shifting faster there is less time the clutches make contact, thus producing LESS wear on them. I think I had a best 60 foot of 1.78...but I only ran high 13's...then again...I was mostly stock with a few bolt ons....still on manifolds...stock tune...etc.

Basically...don't drive your car like an idiot and you'll be fine.

Thanks for the info!
