Modified Spark/OBX/Meng manifold need opinions/ braced it already
I just got my Spark racing manifold back from the machine shop. I had them brace the hell out of this manifold. They braced every runner and the wastegate too. They also ported out the wastegate hole to the size of the gasket to prevent boost creep. My question to you is, Should I have expansion slots cut into the flange or drill out the bolt holes a touch bit larger? Here are the pics of what I had done. Let me know what you think. Thers no point in selling this manifold at this point because being that I am Canadain I can't afford to drop more coin and buy something different. The manifold is heavy as **** right now with all this extra metal on it. You won't be able to see the braces once its on the car.

drilling the holes slightly larger and using washers should work just fine to take up for expansion. at least it has for me in the past, and of course many others.

SIXTYdashONE- That was my question, where would you cut the expansion slots? In the bolt holes or inbetween the bolt holes from each cylinder?

Hey that looks like what I used to make with Popsickle sticks and throw them against the wall and they all busted apart!
Now that's what I call bracing!!!!! Ask Geoff about this, he had made some comments about bracing it causing it to crack more, I could be wrong though. I think the main concern was at the wastegate to the mani though. Good luck.

Yah, i will back him on this one also. Reason being is because the metal they use to make those manifolds are basically recycled soda cans. Other top quality equal lenght manifolds use a stronger guage metal.
And to answer your question from before, id say cut expansion slots for each runner, and not for the bolt holes. good luck man..

Have the same manifold! Been boosting 20psi with SC60 on built gsr for 6 months. No cracks, no problems, no bracing!

Re: Modified Spark/OBX/Meng manifold need opinions/ braced it already (dmecarboy)
dmecarboy- whats your setup if you don't mind me asking? Looks like your making good power. Got any pics?
As for my manifold, I am just going to try it out and see what happens. I have some custom brackets being made by my nieghbour for my downpipe. Its going to stop the movement of my exhaust so my turbo doesn't move around a great deal. Its going to have bushings placed in the bracket to absorb some of the shock of just day to day driving. My car is going to the bodyshop for touch ups and they are going to cut out my front bumper for my intercooler. So when I get her back its on. Maybe she will stay together, maybe not. Time will soon tell. Any comments on the expansion slots? Is it worth it yes or no?
