This is for all of you who know about boosting or spraying the D17. Its to my understanding that the intake manifolds are plastic. Now for the people who have sprayed or boosted, how have you gone about not cracking the intake manifold from the pressure? Does the manifold take so much or have people been swaping them out for aftermarket manifolds. I havent been on the site in quite sometime and wanted to see what everyone was doing or if this posses a problem. Thanks for your input.

I run at 9 psi , and have spiked at 12 a few times w/ the stock manifold and its holding up fine.

Hey captain you should be fine. I got a custom intake manifold on my motor b/c i was gonna go turbo. It has side mounted throttle body to. But im selling my motor now, got k20a2 swap

But if you had a built motor and were going to run more boost wouldnt it be a must to upgrade manifolds?

i have mine set a 8psi with a 35 shot of nitrous and the car still runs fine. alot of new cars have plastic intakes. my friend has a 01 trans am. it has 330hp with a plastic intake and supposibly those cars love nitrous.

plastic intake manifolds have nothing to do with anything. I mean, a majority of your vehicle is comprised of plastic. They make very strong plastics, trust me.

I'm not saying it will explode of crack, I am just thinking that it would be logical that it would happen under alot of boost or the nitrous freezing. Not trying to start any debate. Just curious on the issue. Thanks guys. If anyone knows of anyone selling a block...let me know.

yes is does seem logical that it would crack, but im hitting over 12psi and its still in one piece

Crack the manifold...doubtful. The thing about the stock manifold is how restrictive it is. It doesn't allow a whole lot of airflow. When building the motor and boosting more pressure, I will definitely be getting a new one.

What all do you have done to run 8psi daily ?

nitrous mixed with gas is hard to freeze!!!

The stock intake holds up fine. People who have
bout the KMS manifold lost power....and 500 bucks
