Top Mounts
So do you think utilizing cast manifolds to design a top mount twin would eliminate most of the heating issues, such as needing a hood to aid in cooling.
Thinking if the manifolds led to a ~6" section of 2.5" pipe coming from manifolds into turbo from underneath. The turbos would be placed parallel to the frame rails running front to back. They would have a 3" downpipe over the manifold then a straight shot down and into the rest of the exhaust system. The downpipe would not crowd the hood like previous kits.
A heat shield would be used on the exhaust housing. (DIY stainless pot heat shield
)
The downpipe will be wrapped. The coils will most likely be relocated, or possibly shifted up.
So do you guys think this would possibly eliminate the heat issues must kits would run in to.

Thats why I'm talking about using a factory style cast manifold that will not crowd the hood like those kits do.
The PTK kit has all the primaries running up towards and near the hood, this crowds downpipe placement as well.
With the cast manifold itll be able to feed the turbo from below and not the side or top...IE the turbine inlet will be facing downward. This will allow the downpipe to exit the outlet until it passes over the manfold then exit down very tucked to the engine block since the manifold hugs the block.
This will pretty much eliminate the need for a hood correct?

You're saying top mount but then you want to install the turbo's underneath like a convential turbo system.
A turbo mounted on the side of the engine like the TTiX and APS kits does take the heat away from the hood.
The Ligenfelter system also works that way.

No no no
I guess pictures will help me explain.
The turbo will be in this position but with in the exhaust turbine inlet facing down allowing the pipe feeding the turbo to come from low and not running near the hood like this one. Then with the added room the downpipe can also be routed straight down over the manifold unlike ones like ptk and this where the primaries take up room.
The pipe running to the turbo will be basically be in between the ac compressor and top of cylinder heads.
Will this eliminate the need for aftermarket hood?

With a set-up like that you're going to have all kinds of heat problems. You'll have to relocate your coil packs, washer & cooling tanks and what not.
Your hood will need to shielded, etc ... as well as anything else around it.
The way to go is with the turbos underneath.

I don't think that I'll have that many problems, I plan on moving the coils already I'll be covering the tanks I'm just worried about the hood. And are you saying this about the lingenfelter kit sits you are partial now that you have one. This setup will be compact like that of a supras but also using cast which gives even more room and heat retention.

the only thing i have seen that uses the stock manis (apart from the sts) is custom HP look-a-like kit. that had 3.5inch downpipes!

I'm not making it like the hp it'll be a top mount like ptk but with turbos running front to back not the way they are placed in the ptk.
I'm not wondering how to doit but whether or not there will be heat issues with turbos located a few inches further down.
