can anyone tell me how hard it is to put one in or how much it would cost to have put in and what exactly it does.

I'm assuming you have an L36?
I installed the GT1 cam in my bonnie. It is a VERY nice mild cam. It dosen't kill the low end and it is capable of making great top end power.
With higher compression and most of the bolt ons available it made 233 whp.
It put a grand prix gt at 14.2 in the 1/4 with most bolt ons minus heads. They are lighter and better geared though so keep that in mind.
I was able to install mine with little experience but it is very involved and a lot could go wrong.
As far as how much it would cost to install, I'm not sure. You would probably have to get quoted by shops close to you.

do i need any certain modifications done before i put on that cam right now a have a secret weapon intake a drilled 180 deg. thermostast

You might want to PM BigNews1 and ask for him to take a look at your thread. I know he'* sidetracked with an issue or two.....but he'* done some amazing work on his car using modified stock parts.

You might want to consider having stronger valvesprings installed at the same time, though I believe some people run the GT1 on stock springs. If you get new springs, I can't remember for sure if you would need different valvespring retainers or not. Someone else will be able to tell you for sure, or you could ask ZZP when you're ready to order your cam.

Chances are you will want a different PCM program to complement your cam, but it isn't vital. The car will still run on the stock PCM, but you will probably be running lean in all RPM ranges. Also, you might need a few of your trouble codes tweaked. The GT1 is not known for setting a "random multiple misfires" code, but I think it happens in a few cases.

All in all, you have to invest a bit of money to get a cammed car to run at its full potential. You can't just have the cam installed and expect it to run perfectly. There are issues that need to be massaged in order to develop full power.

Already on the job, boss

Altiery54, me and MIke (95naSTA) will send you down the right path.

With the GT1 you should install 100lb or 90 lb valve springs with LSx style retainers. The 100lb springs are a little better because they don't build pressure as fast as the 90lbers. In other words, the 100lb springs will put less wear on your timing chain and damper.
When installing the cam, be sure to replace the timing chain and damper too.
ZZP does offer pcms that go with the cam. This should have the modified spark/fuel maps to make your car run correctly with it.
BUT
If all you have is a 180 thermo now, I would just say do basic mods (CAI, high flow cat, PEMs, etc.) first, get familiar with the engine, and then plan out any major modifications.

i am thinking i might just take it easy and do some more basic stuff and then see where it goes from there thanks for the help i very much appreciate it
