where to buy exhaust & turbo flanges?, go'n six, might as well blow the 4 first Options

Hey guys,
I'm going to run a turbo on my -4 for a season or two because the local club rules are just begging for it. Hopefully by then the six will be ready to go in. Anyway, the EFI has been on and running for almost a year and I've got all the turbo parts - just need to plumb it all together, and I need flanges.

Anybody know a good source for turbo and exhaust flanges? It's an IHI turbo. Haven't had much luck so far with the header people.

I decided to reply again.

I really really want to be involved with the production of a Turbo header for the 914.

Give me the specs on your turbo (everything) so I can determine what length the primaries need to be. We have the original engine and trans "jig" that was used for the 914 SSI's... so I have a good start. We also obviously have the tooling for the stub flanges to head.

I REALLY like what you are planning to do, but I'm just working on a junkyard turbo to keep me happy while I'm gathering six conversion parts. Low-buck, low-tech all the way.

As far as primary tube length, I'm not even going to worry about it on my project. There are so many packaging problems to solve that they are just going to end up being whatever length gets them plumbed to where I need them. I'm just using cut up 1.7 heat exchangers. Stubs would be nice, but... I'm too cheap. Like JP says, "cheep is gud".

Just FYI I am placing the turbo directly opposite the starter. This is a nice location in that it keeps the turbo out of the engine compartment and keeps the primaries relatively short, albeit quite unequal (not such a big deal). Only cutting is to pass pre/post-turbo intake and oil line through the right-rear engine tin upright. Downside is that there isn't much height for oil drainback (but enough), and packaging. You look up there and think there's all sorts of room, but once you start stuffing the turbo and plumbing in there it gets really tight.

If the header isn't overly ugly when I finish I'll send you all the pictures you want if it'll help in your R&D efforts (file under "design techniques to avoid"?) (IMG:style_emoticons/default/blink.gif)
