Cam ?

[99M6Z28]

I am working on a budget so I wanted to see what everyone opinion is. I want a cam but i know I need an intake and headers also. How much will I choke my cam if I do the cam first? I want a TR224/224 LSA114. Is this too much cam for stock heads and intake? Can I get buy with just headers? Or will I need headers and intake? Any help will be appreciated!

To optimize the gains from a cam, yes you should do the exhaust work first, headers,Y-Pipe, CB etc. As far as the "Intake" do you mean LS6 manifold? Lid/filter? What part of the intake are you speaking of? Lid should be one of the first mods for the car. And finally no the TR224/224 won't be too "much" of a cam for stock heads, in fact it is one of the favorite cams out there because of it's gains and reliabilty for a DD car. If you track run the car you might want to go bigger. The TR224/224 with a good tune will pull nice HP/TQ gains from 1800 RPMS on up with other bigger cams peaking it up top, above 5000 RPMS.

I already have a Mac ORY-pipe, and Borla exhaust, SLP lid with K&N filter, all the free mods, and I am about to port the TB. This is my DD. Is th LS6 intake necessary, and how long can I get by without a tune?

minus headers, expect about half of the gains a cam would give you.
me getting a 224/224 cam gave me a 39 rwhp bump with tuning

I plan on headers just not at this time. I would also like to get an LS6 intake in the future.

Ahh, the beauty of Mass Air Flow. You should be 'okay' with the stock tune for now, as that cam isn't that big. I'd consider bumping up the fuel pressure a tad though...

[99M6Z28]

With bigger injectors or what? I am kinda new to the internal mods.

You're stock injectors are fine, bigger injectors only come into play when you add more cubic inch displacement. An AFPR (adjustable fuel pressure regulator) can alter you're engine's fuel pressure. The bigger the cam, the more air you'll flow... the more fuel you'll need.

I just ordered the TSP 224R on a 112LSA and i am hoping it will turn out good for a daily driver on stock tune with an M6. I did a lot of research and this cam is very popular because of its great gains and drivability. Ill let you know how it goes after the install if you havent made your decision.

With that LSA You're going to want a tune ASAP, anything lower than 114 and the car will run very rough. As for getting a cam before your headers and intake I suggest doing all bolton mods first. Then get a custom cam matched to your heads and optimize your setup. I bought my last car and it already had a cam and ls6 intake, loudmouth exhaust. It was a mail order tune and still ran rough. I bough heads, headers, and got it tuned. Ran so much better and I gained 70 HP and had better gas mileage. Now I'm getting a custom cam made to support all I have done and match what I want out of the car. The car has a 112LSA cam that ran too rough without a tune and headers, It back fired all the time and sounded like Sh*t through the LM. From that experience I wouldnt do the cam before I could let it breath properly and get the most out of it.

youll need to tune it. i drove my car around with a 224 cam for about a week.

Will the 112 pass emissions even with a good tune?

Probably not, but if you detune it and got some good cats you might make it by. Alot depends on what your county is looking for during emissions testing

[99M6Z28]

Flobeats385 that sounds great! Let me know how everything goes with the install. Also, what are your current mods?

[Hurley711]

PA is kinda tough with emissions, how does the 114 pass and the 112 doesn't? I don't undersatnd the diff.

The 114 Has more negative overlap than the 112. 112 is a little more aggressive and harder to tune, but makes a little more power up top. You can still fail emissions with a 114, you just need a good tuner, the stock tune won't work.

Hey man if you want good torque and drivability get the Comp cams 116/220@114lsa - that cam with stage 1 heads and full exhaust put down 402hp@6000rpm and 390ftlbs@4800rpm - look on www.thunderracing.com - I have the CheTr cam 214/230@117lsa it idles stock and put out 390hp@6300 and 375ftlbs@5000 with my car with cleaned up stock heads and full exhaust!

[Flobeast385]

sorry its took a while, i just now got my TSP 224R cam installed along with 918 springs and PR. tomorrow i just have to put the radiator in and fill the fluids and let you know how it works out.

[99M6Z28]

That sounds great. I decided to wait on the cam for a while so I got a set of long tubes. I am gonna do the supporting mods first but I would still like to hear how it turned out. Did you do it yourself? Any problems and how long did it take?
