well .. hell .. interesting turn of events. i've been talking with brandon from flyin miata and he's been extremely helpful. he suggested that my alignment issues and whatnot could suggest that the head is not a 97 .. and in fact, a 99. He told me to check the back of the head and if it says BP4W.. then it's a 99. well .. go figure, that's what it says (picture)
this never even occurred to me as a possibility because I was told i bought a rebuilt 97 engine.. i guess now i actually bought a rebuilt 99 engine?!
so that's good and bad ....
bad, because this is not something i was prepared for and now have no idea what needs to be changed with my setup to make the engine work with the rest of my car!
with this new information .. what is necessary to get the car and engine compatible?
below is my list .. what else do i need to add?
-99 intake manifold
-99 intake manifold gasket
-something about an MSD RPM switch.. what's this?
-egr pipe compatible with 99 head and FMII turbo exhaust manifold
----assuming the one FM sent me with the 95 turbo kit is no longer compatible
-fuel feed rail.. my 95 one feels a bit tight
so .. what can i add or remove from this list?
what changes will i need to make within megasquirt to account for a different engine?
EDIT: another thought .. since it's a 99 head ... does it mean the entire engine is a 99? does that make a big difference over a 95 or 97 engine? as far as compression or anything with the cylinders/crank?
