I was looking at the 6758, I'm curious to know the spool on a 1.8 and what kind of power one would see at 20psi.. With this Absurdflow manifold. My only concern would be bracing, which looks like it would be a pain in the *** to figure out. ![vash](https://www.miataturbo.net/images/smilies/vash.gif)

Or Abe/ARtech will weld your OEM waterpump inlet pipe so you can flip it 180deg. and use it as-is, he does this for cheap. Then run a cheap radiator hose "t" if you are still doing a heater core.

Yeah, I would. Top down in the 40's is a little brisk, but I can handle it. ![Sad](https://www.miataturbo.net/images/smilies/sad2.gif)
Regardless, it's a huge tug-o-war over what kind of setup I will go with, el-cheapo GT3071 and leave everything else as-is, or muchacho 6758 twin scroll.
I've been wondering what boost levels I can push into this block without blowing it, I never really looked. I'd guess the head gasket would fail first..
