Thermostat housing in the way of bigger turbo

So we've gone with a larger turbo and the thermostat housing no longer fits in the car. We'd like to keep the thermostat because we live up north and from what I've heard the thermostat is responsible for heating the car up quicker? Does anyone know of a thermostat housing for the zebec that just goes straight out of the block (toward the riverside fender), instead of the stock foci one that makes a 90 deg bend (towards the front of the car)?

We have a thermostat bypass, its just a big aluminum tube that mounts to the thermostat hole but is this something that you'd run on a daily driver? Also how would you run the coolant lines to the oil cooler on the back of the block?

You could buy a Bostig unit and have it machined to accept a thermostat in the side... you'd have to fab up a connector for it, and I think you'll have to fab up a few curves to allow some of the available tubes to fit well enough.

Thats is a possibility, the bostig thermostat housings are gorgeous but the price tag is scaring me off a bit to modify one, I'm not THAT confident in my machining skills haha i found them here: http://http://www.bostig.com/bostig-billet-thermostat-housing-for-zetec/

I was hoping that there would be a stockish version for another car equipped with a zetec? I will look around but someones gotta know

If i did have to go the fabrication route, I was brainstorming while falling asleep last night, I could make a 1.5"-2" extender plate, similar to a throttle body spacer out of a block of a block of aluminum and just keep the stock thermostat

Could you extend the OEM one farther away from the head? Get a piece of aluminum machined with both flanges and extend the housing out how every far you need it so the hose clears the compressor. Or, are there any in-line thermostat housings? You could delete that, bolt on a flange with hose barb to the head, and then split off your hoses with T fittings.

You've turbocharged your car, but aren't 100% of the job that the thermostat accomplishes?

Somewhat alarming, but i'll let this play out.

^That's nice (good ol' Top Speed)... did they recommend a hose that fits to the radiator as well?
