    P0507 error code and next steps

    Hey guys, I'm getting the P0507 error codes and we found the problem to be a cracked/leaky intake manifold. So it looks like I'm in the market for intake manifolds for replacement. My current setup is a FAST LXS 78MM intake setup with a Thunder Racing throttle body. In your opinion, what is the best intake manifold/throttle body setup currently available on the market today for the LS1 motors? I have a 1999 Camaro Z28 with the 5.7L LS1.

    Thanks!

    With stock internals and exhaust (headers) the best bang for buck would be a LS6 intake. You can find them used for about $350-400. Now if you have cam and heads a FAST 90, some seriously flowing heads, cam and a stroker crank then a FAST102.

    I plan on getting the trick flow 515HP head setup, so would it be better for me to get the FAST 90 now? I also have headers and full SLP off road exhaust on right now. I'm also running the K&N air filter ram air intake, but I was thinking of changing this to the SLP lid intake, is that worth it? Does the SLP lid intake come with new tubing to connect to the throttle body with?

    SLP Intake , no it is just the lid.

    Does that Trickflow head comes with a Cam?


    If in the long term it would be best to do a H/C/I (Heads/Cam/Intake) all at the same time. Reason being is because of a tune that will be needed. You can do the intake for now without needing to get a tune right away but at least a mail order tune like from Frost to get some benefit from the FAST 90.

    With the LS6 you really can't lose $$ on getting it now and selling later. I got mine for $300 and sold it for $400 3 yrs later. You can also use your throttle body with the LS6, not sure about with the FAST90. May need to add a new throttle body to go with the 90.

    I may look into getting the LS6 for the short term just to solve this issues and get the fast 90 when I'm ready to do the heads like you said. That does sound like the better option. Here is the head combo I'm looking at: https://www.summitracing.com/parts/tfs-k306-515-460

    That combo will put you with a good tune about 410-420 at the wheels. The cam is a 228 which makes it better than stock but also a nice daily driven with a nice bump in HP.

    Is the TB a 3 bolt like the stock one or a 4 bolt? Seeing how Thunder Racing is no longer in business, it's hard to find a pic of one. Funny thing the owner that was the brain trust of TR is the guy that tuned my car. Long story short, he got divorced from his wife, she got the company and he walked out with his experience and knowledge. TR went out of business within 2 yrs. He has a company called EPS (Engine Power Systems). Great guy.

    Here is a LS6 for $390.

    Have you been able to find where your crack/leak is? Some of the epoxies out there are so good, that a repair would be just as strong as the original material, and even cost less than the cheapest intake manifold. If you are looking at making major changes in the near future, why not try a good patch job for now, saving up front money and time? The worst that can happen is the patch doesnt work, and you have to buy a manifold, which is where you are at now.

    It's not really visible, we detected it using Carb cleaner and an advanced scanning tool. It's on the left side (I think bank 2) if your looking directly facing the front of the engine.

    I don't mind getting the LS6 for now just so it can pass emissions in the state of Maryland. I may even keep it for awhile, because I'm not sure when I'm going to do the other mods.

    if you pull the FAST 78 off, check the lower shell of the intake, mainly the valley cover bolts to make sure they were swapped out when the 78 was installed. If not people have reported that the factory valley cover bolts will crack the lower (bottom) of the intake manifold. Fast intakes can be disassembled.

    This might help:
    Porting, Prepping and Painting a FAST 90 Intake Write-up (tons of pics)

    As stated, there are ways to fix the issue. Explore that option first before dropping money for an Ls6, unless time constraints are an issue. Sometimes the fixes are easy. Good luck!
