Mazdaspeed HG vs Reroute?
I know I read somewhere that the ports in the Mazdaspeed MX5 HG force water through the head better than the 94-up 1.8 gaskets but for the life of me i cant find that thread. As good as reroute or not?
We are building a 97 motor for track use only.
Thanks

It's the 2001+ HG rather than the MS HG IIRC.
From what I understand the 2001+ HG is better than earlier Miata OEM cooling systems, but not as good as a proper re-route.
You shouldn't run both either, it's one or the other.

The optimal solution is to run the 99/00 head gasket with a reroute. There is a big long thread on m.net about it where we compare them all. Jasonscb also put some additional holes in his and says it is working fine.

Go figure I put my reroute in before we "discovered" the revised 01+ HG. My solution will be to add a front t-stat/t-into the upper rad hose rather than removing the reroute. The dual t-stat setup isn't all that bad, but Hyper's way of going about it and over complicating it and using a nice big metal pipe over the exhaust manifold.

Jason states his car ran cooler, based on his comparison w/ and w/o the 4 new holes he added. I can't seem to figure out if he was running a reroute at the time. Does anyone know? I wonder if he recommend the risk of ruining a gasket again or if he has a new way of punch those holes.
