Ok I know this is a well talked about topic in this forum because I have been reading posts after post. I just wanted to get an opinion from someone else on this forum. I have a custom made 420A 14b turbo manifold and had some problems when I installed it. It didn't line up like it should have as if it wasn't angled right on the block. It had a gap on the bottom that just didn't seem right as if it was worped or something. So I just took it off and put the car back to the way it was. I saw on here that someone actually attached a square flange(turbo) to the round flange on their stock header. I was wondering how that worked out because it didn't look that effective in keeping the exhaust gases in the pipe but that just me. I know there are a couple of guys on here that can make the manifold, but I don't really want to spend money on a new one. So I guess I have two questions.
What does everyone think about attaching a turbo to a stock manifold?
What should I do with this worped manifold? Can I take it somewhere and get it fixed/fitted right for cheap/good price?

well, i m building my turbo kit and I have been looking for turbo manifolds for a while...
you don't have too many options...
1 buy a flange, pipes and weld all that crap together....it will crack eventually....
2 find someone that welds better than you and tell him to do No 1....it will crack too, just later....
3 break the bank and get a Hahn one or equivalent
4 there are some on eBay for $200 shipped, but I don't really trust it
I ve been looking for one for the past month, after considering all these options, I went with #3... cause I don't want to have to fix things that require welding, simply cause I don't know how !
i personnaly would not spend time/money on that stock f*ckd up manifold you got...
Good luck with your setup

ok so how much does a hahn racecraft manifold cost and how reliable are they? Also doesn't it come with the 16g flange on it. Does that flange fit a 14b turbo?

Yes they come with a mitsu flange, which means the 16g and the 14b will bolt up. Making a custom manifold doesn't mean it will crack and if a good welder does it it probably won't crack. I have had mine for 14k miles now and it cracked once right on my crappy weld, I re-welded it and haven't seen a nother crack. I'm considering getting a manifold from www.thestreetsource.net though, A bunch of guys have his manifolds and they are good quality. Call him up and talk to him, you will have to special request a mistu flange if you want one though. I don't think it costs extra.

Um no. The 14b will bolt up but it will be sideways.

Yeah, GREEEAAAAT QUALITY....
Just buy an HRC kit or at least the turbo and manifold. You'll save so much time and money in the long run.
If you think buying an HRC kit is "breaking the bank" then you SERIOUSLY should NOT be going turbo. The kit is a small fraction of the total cost.

You sure? My friend with a honda got a manifold for his car with a 16g flange and it put the 14b right where it needed to be. I also thought that a 16g was a direct bolt in for turbo dsm's and didn't require any modifications to the manifold?
You are the first I have seen complain about the quality of his manifolds.

I've heard of a very few people saying that they had to get the flanges machined flat, but never anything like that. Other than those few with the flanges, everybody said those mani's were great quality.

So I had a header put together and I was wondering what are the chances that it was actually got worped? I know GSgoinfast custom made his and that is what I was going off of. so I am not to worried about the quality because I am just trying to get my foot in the door and when I find that the whole system works I will begin to tweak it and upgrade shit after a while. Did anyone who custom made their manifold have a gap on the bottom when they tried to match up the holes and put it on? If so how much of a gap and I guess if you did't that means that I have to get that freaking piece machined flat.
cause I don't want to have to fix things that require welding, simply cause I don't know how !
