I5 forum, wahoo!

So I've been doing a pretty major overhaul of my 1990 200 TQ Avant and I've been trying to find a source for a aftermarket manifold/header.

While I have found someone who will make manifolds/headers for people using EFI setups, I haven't found anyone who makes one for the stock CIS setup. With the manifold sandwiched in the small space between the engine and the turbo there isn't much space to work with.

Has anyone here seen or heard of any options besides Dialynx or the two-piece from the stealer?

Is there anyone who might be able to cast one out of something other than iron? Nickle maybe? Maybe some of us can get together to get a few units made at once.

I don't feel like it makes much sense to use the stock unit as mine was cracked in 3 places and it will probably crack again if I get it welded up. However if I can't find anything better I will use that method. I'm not as concerned with it increasing performace as much as increasing reliability, however I don't want to lose much/any either.

Any good metal work shops in the New England area that might do a custom/one-off piece would be good to hear about because I don't know about any of them.

The CIS system takes up too much room to do a custom tubular manifold. If the CIS is gone there are many options for exhaust manifolds as you stated.

I think the two-piece which allows for some expansion is the reliable option while keeping CIS.

to justify putting a header on. Toxcheep seems to get around this somehow.

on his 80 while it was 10vt, he has since gone to a 20vt monster that produces 500bhp:)

The big issues is the airbox and airflow plate being in the way. EFI is in your future!

Cheers,

you used a 20vt head gasket... what is the advantage to using it over the stock 10vt head gasket? I'm gonna order a head gasket and head
bolts today and was wondering if I should with the 20vt gasket.

With the header it's really about having one that's not gonna crack. I would go with the two-piece manifold but the price is hard to swallow.

while I'm at it, how much do the ARP head bolts run?

cheers

For headstuds, see<ul><li><a href="http://store.summitracing.com/default.asp?target=esearch.asp&amp;Ntk=KeywordSearch&amp;N tt=Audi+5+Cylinder&amp;PartSearchFlag=On">http://store.summitracing.com/default.asp?target=esearch.asp&amp;Ntk=KeywordSearch&amp;N tt=Audi+5+Cylin

more about CIS than just about anyone...

I don't know who anyone is yet, I guess I'm just too new around here. What are their forum names?

Cheers,

Myke is known as Toxcheap and Den is famous for the car name ... evilwagon. like i said, i don't believe Den gets on. check out their site @ www.toxcheap.com

Does anyone know if the summit racing 8mm nuts are copper?

Eagle day has copper nuts for less. ( 4 for 2 dollars)

The plated internal hex bolt kit they sell has been invaluable. With the washer kit and some of std. hex head bolt kits its pretty everything you need.<ul><li><a href="http://shop.store.yahoo.com/eagleday/sohebo.html">http://shop.store.yahoo.com/eagleday/sohebo.html</a</li></ul>

And they are multi layered... like 4 layers...vs the mc's 1 layer... Is this making for a thicker HG? Yea i knwo what you mean James about those hex nuts......

I'm not sure about a 10V gasket.

The KW was a thick 1 layer fiber piece with metal rings around the piston openings. The UrS4 gasket looked like a superior product and was about the same thickness at the KW.

I'm not going to look to see if I saved it either, as I don't want to step on any toes.

Myke will let some of the secrets go, but I also know that he's the type of person who thinks that "hey, I/we spent the time and money to figure it out, so should you, or at least attempt it and put some thought into it first". I'm sorta the same way.

as koop says, gotta figure it out for yourself. Maybe if you were tryin it and were having trouble, he might, but i can't speak for him.

Is better than any CIS modified to the brim(correct me if I'm wrong)
But then again the tricks Myke and Den used had to be a lot cheaper than switcing to EFI. Thats the whole plan, speed on the cheap! ;)

I'm going with a stock manifold that has one crack in it and I'll have it welded/brazed up before I put it on. At some point I'll try to find out some stuff from Myke and Den but for now it's a matter of getting the car running. I'll update you all on how it all goes!

Cheers,

I have a 2-piece MC exhaust manifold ("Port Matched" to gaskets) with wastegate mounted + 1.8 Bar spring installed, I also have downpipe & cylinder head (also "Port Matched") less camshaft & followers. If anyone is seriously interested contact me directly at: quikqtr@yahoo.com
