I have a 1990 TII with the 13b-t ..... I am going for a T-66 turbo and I am looking for an exhaust manifold with thick inconel flange (T4) and 348ss (or other) pipes that can bolt a 44/46 mm wastegate. The problem is that I can't find any.

Does anybody knows were I can get this kind of exhaust manifold ?

Thanks for your help !

If you need more details, just ask !

 

Also, a divided manifold would be the best !!!

 

If you want Inconel, you are really going to pay for it. I'll just give you a hint at what it costs, if you were to buy 1- 2" u-bend pipe which on it's own isn't nearly enough to buld a manifold, that one piece of pipe is about $220. Custom flanges would be extremely expensive. It is also very hard to cut and work with and definitely not for the amateur welder. You don't need Inconel. 321ss is good stuff but it isn't cheap either. It is however cheaper than Inconel and easier to find. There are a few companies out there that sell stainless manifolds but depending on which grade stainless they are, you may need to build one yourself or have one built.

 

For your piping needs http://www.burnsstainless.com/Incone...coneltube.html they don't even have pricing on their catalog you have to call them to get pricing. Just like rotarygod has already stated you don't need to make it out of inconel, stainless is fine. And if you still want it to hold up to the heat of a rotary get it coated with jethot-2000 degree coating from http://www.jet-hot.com/pages/headercoatings.html will still be cheaper than then inconel.

 

http://www.burnsstainless.com U can find all here. But u need to build it u self ore get somone to help u Hope its helps ..GL

 

the price of it is not a problem .... I know I can pay around 800$ for a good one, but I don't care to pay for good things... And I want a inconel one because the car is going to be a track car (road racing, lapping, ...) and I don't want to change the manifold every year ......

thanks for your help !!!!

 

Flanges $1200+
Tubing $500+
Cutting/fitting $500+
Welding in a gas perged enviroment $500+

There are reasons that only race teams with million dollar budgets use inconel...
Just my $.02 from having worked with the GODFORSAKEN stuff.

 

You can make 500rwhp through an HKS cast manifold with excellent spool, and it will last ten years on the track. Why not that option? If you really want the slightly faster spool of a divided tubular long runner manifold, they cost around 600-1000.00, and will last you three to five engines at least . Carl

 

This is bad2ndgen's site http://www.alienauto.com/ since he has experience with inconel and rotary's you might want to contact him. Hope you don't mind the plug bad2ndgen.

 

Oh god! I don't want to work with that sh#t!... Thanks though.

 

But if the price is right and this guy doesn't seem to care about the cost it might be well worth your time. But I know how you feel sometimes the money doesn't out weigh the headaches.

 

Im not saying I wont do it, I will just cry the whole time...

 

thanks for your help ! I'll check this out ....

 

We can and have done inconel manifolds they are very expensive. You really have no need for it though. It's not really too hard to work with just expensive material costs.

 

ok ! I will check it out !
