Hey guys whats up?

Questions: :rolleyes: (1) Will porting my Intake Manifold and/or throtle body throw me any codes and check engine lights?

(2) Will it affect reliability?

(3) Has anybody done it? And what were the results

:skep:

Thank you all.................... :)

 

Anybody????

I really don't want to proceed without your valuable advice :steering:

Thanks

 

Here is what I did.
1)I ported and polished my throttle body. There is a good article on exactly how to do it by chuckster. He's on the forum. I can't speak for him but if you ask him I bet he'll email you a copy of the article.

2)I didn't port my manifold. I don't think that is something I would want to do, especially on my LS1 manifold. I don't think I would gain anything and probably would hurt performance due to flow velocity changes. I swapped my intake manifold with an LS6 and got a good boost in performance for the dollar invested, and it is an easy change.

3) I also installed a set of SW headers 3" mid-section, and xpipe w/ hi-flow cats.

4) I haven't affected my reliability, so far.

5) My results were:
Prior to the above changes the car was stock with: VaraRam, smooth tube coupler, Corsa xpipe, and Corsa Daytona exhausts. RWHP=318, RWTQ=322.

After the headers, intake manifold swap, and throttle body porting, RWHP=347.3, RWTQ=356.6

I personally don't think you will feel any difference in performance SOTP from porting your throttle body, and I wouldn't swap the intake manifold without doing headers and pipes. If I were only going to do 1 thing, I would do long tube headers to start. Just my $.02

Good luck! :thumbs:

 

Thanks you VERY much for the response...

Will just porting my throtle body with everything else stock help or actually hurt the performance of the car? Or just like you said I simply will not feel anything.....Do I REALLY need lets say a Z06 manifold or lets say a C.A.I to go with that???

Big thanks for responding...

 

As I said, I would not recommend swapping your intake manifold without putting on s set of long tube headers. Porting your throttle body is a nice weekend type project. It will take a lot of sanding and patience to do but when it is finished they do look great. I took the time to polish the outside of mine also. It looks like chrome, so asthetically it was a plus, but I didn't notice any difference by porting/polishing. Maybe if I measured it on a dyno I would see some improvement, but I didn't do that. It was a fun project though. Maybe someone will jump in and give you some other opinions/advice. BTW, I think my polished throttlebody looks really :cool: on the outside AND inside now. :D
