Hey guys I haven't been on here in ages. But I guess that's what happens when you join the army. So I am almost finished with my training and about to go home. My dad called me a few days ago and told me my 99 grand prix gt had started leaking coolant around the throttle body and plastic intake. SO first off I guess my question is how hard is that to fix and how much.

I also have a buddy who wreaked his 05 comp g gtp a while back it is sitting in his drive way just rotting away. I want to switch the seats but also thought about a top swap while im at it. Just wondering if its possible to do the swap using the gen 5 blower and DBW throttle body and then custom mount the 05 gas pedal somehow. He is only wanting like 1500 for the 05 and I thought that would be a good deal for all the parts.

Let me know what you think. Again like I said, im in the army and it might be hard for me to reply everyday to question or comments so plz don't be hateful if it takes a little bit to reply. Thanks
 


The throttle body has a gasket, because the coolant actually flows through the throttle body. The gasket is cheap and easy to replace.make sure your LIM gaskets aren't leaking as well.

You can do a Gen V top swap, but you need an L67 drive by cable throttle body, which in my opinion is better since there's no lag.

As for a DBW throttle body, you may be able to, I know Bill did the opposite to an L26, but I think it's pretty complicated. I'd stick with drive by cable is I were you.
 
I'd be interested in buying that comp g trans if you want to sell it. Depending on the color i'd buy some other parts as well and can help you pull it apart. You'd have to do a whole top end swap to get the sc to work and you'd have to use a cable tb.
 
yea I would be interested in selling that trans if I get the car. So what your saying is it is just a simple gasket that needs replaced to stop that leak. I remember reading somewhere that it could be the plastic intake because of the heat and over time they tend to warp.
 
your telling me, like I said im not home, AIT in the military. So im like 700 miles from home, my dad called and told me this. I will try to get a pic as soon as I get home (Dec 19).
