Thread: ls1 throttle body

i wanna install the ls1 throttle body on my 97 gtp, and bluegtp91 gave me a quick run down on the chat that pretty much i need a tb adapter plate, flipped throttle bracket, external maf, and tune. where would i be able to get one of these adapter plates from or have made and also would a pcm like one from zzp or overkill or something be able to accomodate for that or would i have to send my pcm to have it tuned?

oh also, has anybody done a write up on this install before for things to look for or to expect?

Not sure about the throttle bracket, or adapter plate, but when doing a different throttle body, you're going to need to get it custom tuned. A generic tune might help get it closer, but it's not going to be ideal at all.

Your gonna need a custom tune. LS1 TB's did not come on our car stock and every car behaves different, ie needing a custom tune to make them work properly with the car.

The Throttle Body Adapter Plate can be had at ZZPerformance last I knew.

Unless you're planning for some serious mods, judging by what you have in your sig, it's a waste of time and money. You won't need a tb that big for a while.

Port the stocker or leave it alone.

I didn't know your mods I was just answering your question.

Honestly for the money you'll see more gains from headers and your car will still RUN after you install them unlike the LS1...which needs a total re-tune.

For $205 get Speed Daddy Headers...then get a 3.4" pulley...those things would make your car destroy a car with no mods and just a LS1 TB/Tune.

Thats just my 2 cents worth.

ah, i just thought it'd be interesting to do really. if the tuning process is gunna be a huge pain or expensive, not sure how much the tune will run but assuming it would be a couple hundred if you're comparing it to installing headers, then nevermind. maybe later down the road then. thanx everyone

You also lose cruise control just so you know.

Oh,

So how come I have it?

I did a write up on one of these forums that showed what all needs to be done to modify the TB, and how to do it. I searched around, and I didn't have much luck finding a link for you. I found a old-old thread on CGP when I first did it in 2005, but most of the pictures had broken Img. links.

I still have the pictures in my photobucket album of when I did it. If you don't have any luck yourself, let me know, I can repost it all.

~F~

This is one I just sold. Best pics I had. You can see how the throttle cable goes on, as well as the cruise. (It was cut and clocked)
