CAST PTK TopMount manifolds
Here was my quote from Wescast-
CAD Modelling for tool build - $10,000
USFPrototype Tools (Mold Plate and corebox) - $18,000 USF per hand (may be able to reduce the cost if we can get a LH and RH on the same tool)
Part prints - $5,000K
Machined parts would be sold at $290 each
So thats 51,000 before any parts. With a run of 50 pairs of manifolds you're looking at an 80,000 dollar initial investment.

damit i would sell my aps in a second for your kit. I WANT GT35. lol
The key is to make a set of manifolds that will work as cast on severla LSx based platforms. Not just the F-Body.
We know for sure these manifolds would work on C5 and C6's. The engine bay is the difference between platforms and a manifold kept closer to the head will have the best chances of fitting the majority.

Looks good AVB!
sounds silly, but i have seen some cast manifold that look similar to tubular designs (see the Ford Cosworth engines of the 90's). could this be done? i would think these would match the flow of tubular headers yet still have the strength of cast iron....
Just thinking that with some coating it would also retain some of the looks of the PTK kit aswell.
Still a great idea.

The idea of 1 7/8's runners I like, but am wondering if it would have any negative effects on spool. As for bling... bosses have been discussed which could be used to secure something like a stamped sheilding similar to NickY's. That way they could just be put on for shows.

What's up bud!

have a look at the HKS Supra Twin Turbo kits. i think they use cast manifolds but look like headers.
Like the idea about the heat sheilds mate! nick reacons they make a massive differance to!
also have you seen this stuff???

it could get around casting costs, but not sure how much they would cost...and it looks very cool!!!

I think a manifold simular to the one in the picture would be about as uiniversal as it would get,it should work on about anything .As long as its a front dump,straight or almost straight.They would look fine coated,I wouldn't worry too much about the bling factor,I'd rather have trouble free which those should be.They should flow enough for any thing except mabye all out race applications,look at the success of the various factory manifolds that are in use in turbo applications.
Anyone in this thread saying that a PTK manifold would fit into an fbody actually own or seen a PTK kit installed in a corvette? Or seen how wide the manifolds are? Where the turbo's are placed? I have not taken my manifolds off and tried to fit them in an fbody but i have owned a 99 SS and now an 01 Z06 with the PTK kit and i would bet there is no way the PTK manifolds would bolt into an fbody engine bay...and if they did..no way in hell turbos would go onto them with the hood on and the radiator in place. Someone prove me wrong and i will be suprised. Infact i will go out to my garage right now with a ruler and get some numbers if someone wants to check.
ok
from the coners of the heads the kit extends about 1' out on both sides and 1' foward to the end of the body of the turbos. about 5" out on pass side between 4 and 6 and 4.5" out between cyl 3 and 5
hight wise at the highest point its even with the top of my fast 92mm intake. this point is at the 2 heat shields seen about 6" foward from the engine on the manifolds.
Here is a pic of what i measured off of to give you an idea of the size of this kit.
No someone with a camaro or ta go measure and find out if it will fit

First of all thanks very much for posting this. This is exactly what I was hoping to get out of this thread 
With the manifold being cast, it isn't going to come out as far away from the block/heads. It will however, be made to use the existing PTK downpipe. Because of the smaller physical size, hopefully when needed, downpipes can be fabricated to fill the gap left by the original manifold and that helps or routing it differently is an option.
I tried looking at F-Body engine bays to get an idea of where there would be issues. I can see there would be if same routing of the downpipe and using the same layout of the wastegate were attempted. I can't tell though if the turbo location/position itself would not clear the shock tower and/or hood and if it did clear, could make it impossible to get a down pipe attached at all. This is of course assuming that the radiator is moved forward as well.
I don't know when but I'll have to plan on taking a trip to a local shop and get my PTK manifolds in there.

hey guys i work at a foundry if i had a mold, i could get them cast . we could do them in cast steel oc wearductle or castiron < and we could machine them in house too . That would kick A#S !
