That manifold will outlast the car, sch40 is very thick. It's not made out of tubing like some other manifolds.



Nice job on the manifold, you are obviously a skilled TIG welder. [/quote]

Yes, it is very thick. The only downside to using mild steel is that it will rust. But so does your turbine housing, so it really isn't that big of a deal.





That is just a cosmetic issue. The welds won't rust. hehe Those are 308 stainless.

I would think about maybe ditching the smaller 35mm WG in favor of a larger one. That looks like a small turbine housing on that turbo. I guess time will tell though how it all works out. [/quote]

The wastegate flange can be changed to something else. Make a suggestion as to what you would like to see on there. Racegate?







Kind of ot but, you said that the turbine housing is small. Will the car be nice and responsive? Or is it going to choke it?

I'm just saying the size may be a bit small. Most people run at least a 40mm. Of course each different manifold design can compliment a smaller or larger WG though. I have no experience with the turbonetics wastegates but have herd some people complain about them. I've never herd a complaint about Tial products, thats why I went with one.



What a/r and trim is that housing/turbine wheel? I doubt it will "choke" it but I'm sure if there were a larger turbine housing on it the .7 front could be taken full advantage of. It just looks a little mismatched is all (turbine a/r to compressor a/r). The rotary likes a big fat turbine housing Who knows you may find that you'll have to go with a .6 on the front because it might hit the strut tower once it's in the car.

You can't beat that for 300-450. It takes time to make these. If I were to make custom manifolds I would charge at least 450 for a divided tubular manifold, maybe a bit cheeper for a simple one. I would say you are offering a good deal

I see what you are saying. Alot of people talk **** about the deltagate... I have installed at least 20 of them, and I have never had a problem with boost creep.





The new evolution wastegate from turbonetics looks promising. The one that I can get right now is what's in the pictures. The other version of it is going to be v band clamps. hehe No more thought about how the wg flange is positioned.







I don't know the specs of that turbo. We bought it from a friend. They had it on a rotary car. The motor let go after 2 passes...





I'll borrow a larger turbine housing and change it out on the dyno. We'll see what differences there are that way.

I think it's just the heat and airflow the rotary puts out that doesn't make those wastegates very compatable. I think it may be a different story with 4cyl piston engines and WG choice.



Thats once thing I'd like to have on my next WG, V-band. But I'm not sure I'll ever need another WG now that I have a tial



If you put a larger turbine housing on at the dyno watch the AFR. I'm sure it will rise as wel as the HP numbers. Get ready to add fuel.

Well, as far as heat and flow are concerned with the rotary / deltagate. I cut a hole in my friends stock manifold, and welded an elbow and wastegate flange to it. It controls boost from 3psi to 12 psi just fine.



That has been on the car for about 6 months with no problems.







V band is the ****. I wish everything was v band.







And yeah, changing the turbine housing is going to lean it out. We have larger injectors, good fuel pump, and a afc. It should be fine for 10psi.

yes but stainless it'self is very expensive



I'm not sure about the steel you are using

I can make it out of stainless for the same price.





Stainless is just bling factor. Mild steel is perfectly acceptable for applications like this.
