1.8L DIY Turbo Set-up with BorgWarner EFR-6258
#42
Sweet EFR setup, I've really been thinking about doing a 94 miata build for some time now but I just bought a 08 mazdaspeed3 I'll have to put those plans on hold for now.
Your profile says western NC, I'm from the Asheville area myself if you wouldn't mind I'd like to check it out sometime.

Yes, the entire turbocharger moved forward compared to a standard FM set-up. FM has the flange centered on the exhaust manifold while my DIY manifold moved the flange closer to cylinder #2. Not sure if this would require replacement of the silicone tube. I'm sure FM would be able to provide guidance.

The dip in the torque curve is actually related to boost control. In the post I mentioned there was a slight overboost at low-speed when the wastegate becomes active. With a little tuning, this overboost condition is gone and the torque curve is 'flatter'.
