Savington recomended I tap and plug my oil pan now while it's off the car and then just install the new oil lines when I get the kit. As far as the TSE Damper, it's on backorder so I'll add that later as well.
The bummer is I'll need 2 tunes, and need to install all of this turbo **** on my own or pay a shop again.

Every single turbo motor we build is 8.6:1 for a reason.

You can but you're going to have to do it wtih ~17-19psi on a GT2860rs and do it with ~18* at the spark-curve peaks while I did it with 12psi at 25* of spark with at least +6* of spark-headroom becuase I never, ever head detonation in my car. That way, when it's 105* out, and you have the tach hung at 6500rpm in 6th at TWS on the front-stretch, you know you get to drive the car home.

He's saying that the 8.6:1 motors produce more torque and have a greater safety margin than the 9:1 motors. You can run more timing on an 8.6:1 motor than a 9:1 motor, and the drop in compression and increase in timing advance produces more torque than running less timing and more compression.

Gotcha. That makes sense.

I had forgotten that AIM told me that secret to power with a BP is as much timing as possible.

I've had this car since it was bone stock for almost 5 years and want to get many more out of it. If it means waiting, I will.
Savington recomended I tap and plug my oil pan now while it's off the car and then just install the new oil lines when I get the kit. As far as the TSE Damper, it's on backorder so I'll add that later as well.

Installing the turbo hardware should not be that bad. Plan a whole weekend for it and you should be able to get everything swapped. As for tuning, I assume that you already had the MS2 tuned for the stock MSM setup or are you doing the initial install of that to?

Savington is correct in saying that you should have your oil drain plumbed for the oil return fitting now. You can either drill and tap it and screw in the fitting, or have a shop weld the fitting on. Either works, I think welding is actually better, but I have had mine tapped for 5 years an never had an issue.

My buddy works here: 1989-2005 Mazda Miata: JSC Speed
I'm going to get as much of the internals as possible from him. Can you guys browse through and recommend some things? I'm particularly confused on rods, some are within 2g, some within 1g. How important is that? Was also considering SCAT rods and supertech pistons (sold by 949racing). If through JSCSpeed, I was going to get the K1 or Eagle rods and possibly CP Pistons or Wiseco. How important is it to get that coating done on them?
Thanks for everyone's help thus far. It's nice to get so much information from one place.

I got my complete engine gasket kit from MAZDASPEED MOTORSPORTS DEVELOPMENT - Home Page
These prices are about as good as you can get for factory/oem parts. Just have to have some race results to get an account. Oh and you usually have to call them to get the results accepted.
The only seal that I have had issue with is the valve stems. But that is a matter of cooking them rather than being bad. Also it wasn't until after I had built the engine that Viton ones became available (or I found out about them).

The stock MSM setup isn't as bad as everybody makes it out to be, especially on E85. I'm not sure you can get all the way to 300 with it. But I bet you can get close and put that planned budget into making the motor better. ![](https://www.miataturbo.net/images/smilies/smile.gif)
edit for clarity. It CAN make good power but other stuff does spool quicker and have much higher power capability.
