GSgoingFast Turbo Manifold

[zwickyj]

GSgoingfast has a how to turbo kit, I was wondering if it was a good idea to make the manifold myself, I have people who can weld for me, what tips should I know also in trying to make a clean kit what is the first thing I should actually do? Which parts first as I can't get them all at once.

It Really does not matter what order you get your parts as long as you know what your are going to get. The only thing you can install a piece at a time is the missing link and fuel system. If you can get the parts to make a mani yourself then by all means do it. If not Mike Hart from thestreetsource.net makes a great mani and a great price.(love you too mike)

When I started piecing my kit together, I took the hahn and star kits lists and made my own followig them as a guide. As I went through, I put prices down of what other people paid for the item, and if I found a good deal, I bought it at that time. Until the end, when I just gave up and dropped 300 bucks on an intercooler pipes and bov, which is still a good deal

The problem with my manifold is that the ports on the flange are wider and shorter then the pipes that are welded to them. I will be trying to port out the slight overlap on each side of the port where the pipe isnt wide enough. Otherwise there is nothing wrong with making your own manifold.

Sort of like putting a square peg in a round hole? Well... a round pipe up to an oval hole if you want to get technical.

When I was originally going to fab my own manifold, I enlisted the help of a friend and competent welder. He suggested making the pipes more oval in shape by heating the ends that mate to the flange and pressing them in a vice.

I suspect this is what they did with the manifold I got from Mike Hart (The Street Source), as I can see marks from the vice. This shouldn't be too hard to accomplish provided you have a vice and a modest sized torch (mapp gas/oxygen or even propane/oxygen).

If you do this step, it should provide better flow without needing to port anything.

Chris, the only problem I see with porting your manifold is that the ports on the head itself are still oval while the manifold now has perfectly round holes - so you still get some flow restriction.

I had thought about heating it with a torch and putting it in a vice, and even mentioned it to my dad(was doing the metal work at his work) but he told me it would just crack and I didn't feel like arguing or risking it cracking as I did not have extra's, so I didnt. If(highly probable) I make a new manifold, I would definitely order extra parts and try this.

As for the porting, I was not talking of porting the flange itself, I was talking of porting the pipe that was welded to it. Grind away at the part of the pipe that is blocking the port. But if my friend ends up getting this mig welder he is talking about, I'll skip the porting and just make a new manifold.

Ok... I see now. Well let us know how it goes.

The guy who was going to weld my manifold together knew what he was doing - he welded two soda cans together without burning a thing... that's skill. Anyway, the point is, is that he knew a thing or two about metal and manifold making. I can't imagine why your piping would crack unless it had something to do the steel composition; so, flattening the tubes can be done safely, I'm just not sure if it can be done with all types of steel.

If you do end up building a new manifold, bronze the old one - it deserves a place on the mantle next to all of the other 420A-T paraphenalia us 2GNTers hold as sacred.

Thats a must! It could be the centerpiece on the dinner table, and we will all relic in its beauty

shoved mine in a vice and havent had any problems yet, been runnin on this setup for about 9 months.
