200 20V cheap exhaust manifold

[OrMar]

Hi there,
I have decided to abandon my big plans with 200 (to go 3071 route) and to do it on an '94-'97 S6.

However, in the meantime I would still like to do something with 200, but on a low budget. Maximum this car will ever see is mild RS2 (330-350 crank HP), so I was thinking about one of the following manifolds:

STR


XS-Power


Or even some SS manifold, like this:


I plan to support it (and/or turbo) and to put flexible exhaust pipes somewhere at cat area. Car is not a dayli driver and I don't have a particular problem if it cracks once or twice per year, so I have to weld it.

I understand Bram had some experience with both STR and XS (and prefers STR), but my question is what would be best solution in my situation, out of these 3 ?

Thank you,
Mario

At the end of the day you pay for what you get, thease manifold will break because they are cheap replicas.

If your going to modify do it properly it will cost less in the end! trust me iv seen it happen before time and time again.

In my opinion if you're only going to drive it as a 2nd car you will probably br in a better cituation to take a little longer to get the stuff, and you will get less p!ssed off towards your car and have a better time with it!

Just my opinion though!

I definitely plan to do it properly (wagner and so on) with S6, but I can't start that in next 6 months, and would like to boost around in something cheap until then.


So, let's resume:

1) is each piece better (in terms of flow) than standard 3b manifold ?
2) will any of these have problem flowing 350 chp (I guess not)
3) which one do you people suppose will be last one to break ?

P.S.
Maybe i should just check ebay and buy used original RS2 item ...

[quattro]

Used rs2 best option and you can sell it on and claw some ££ back if you get a wagner! IMO

[OrMar]

Whichever item I buy now, it will stay on this car. There is one genuine RS2 item for sale on german ebay right now, so i might go for it.

BTW, how does this look for intercooler solution:



It is a Mercedes Sprinter item - I hope it will fit, and that there is no particular difference between diesel and gasoline intercoolers.

The amount of boost you are talking about will blow the plastic ends off it.

[OrMar]

Funny, never noticed that tanks are plastic. There might be some welding en route, than ...

I thought I recognised the IC. I would have thought the plastic could withstand a reasonable amount of boost though

[OrMar]

I thought I recognised the IC.

Recognised it as Sprinter item, or recognised this particular piece ? I bought it yesterday on german ebay.

I would have thought the plastic could withstand a reasonable amount of boost though

Somehow I believed that truck diesel engines are working with more boost than gasoline engines - will have to re-check that.

the Sprinter core is good for small engines... on an 2.2 5cyl. it will couse to much Pressure Drop

[OrMar]

And on smaller engine it wouldn't cause pressure drop ? Could you, please, elaborate that for noobs like me ?


Also, if anyone have a good link with description of intercooler technology and types, you are welcome to post it here.

Thank you,
Mario
