The turbo and intercooler will be sourced somewhere else.
And yes my NB is red, I have posted some pictures online some time ago (also on this forum i.i.r.c.).
Work on it is slow, but as a matter of fact I will be working on it this Saturday.
As long as my rusty Lexus IS200 does not break down too often any more, progress should be steady.
thnx for the answer. His full ecu cost €1000 and a ms-3 will cost €1300. I think that i will spend the extra €'s. Because the ms-3 is pnp and the bs-autotune is not, so i need to cut in the loom. I don't mind to do it but keep it pnp as possible. I'm little bit lazy
Both options are plug and play into your NB-FL wiring loom and fully support VVT. Buying a decent BP-4W head could easily cost 100 euros and then you will have more work and less torque: it does not make sense to me.
BS-autotune should have no problem tuning the MS-3.

I have yet to see a 2560 make more then 300whp on a miata. I have known a few people who have gotten close, but not actually hit it. It is a longshot to say you will get there. I would go with a slightly larger turbo to start with to hit those numbers. The new EFR turbo's are what you want, or if you must stay garrett a GTX2871.

Do it, get a MS3. Other ECUs may work but I have learned from experience that MS is far more popular than most others, at least at the shops I go to. A 2560 -MAY- be able to make over 300 but your torque will end pretty quickly and you're really pushing it; An EFR 6258 will go above 300hp, give great torque and has fantastic transient response. We have a few vendors who can do EFR manifolds now, For an economic build (and if you want to avoid extra work) I'd suggest picking up the Trackspeed manifold. He's going to have solid lines like the FM set so the coolant lines wont get heat rot (I hated replacing them..), already has the manifold and a downpipe is in the works. He's also working on a transmission replacement for when you get sick of swapping out blown 5speeds
