I wonder how this turbo would spool on a 1.6. This might be in my future. Good numbers!

Just a note: This setup is with a ported head and square-top intake.

The work I did on the intake ports was smooth the surfaces and removed the casting flash and remove the ridges from behind the valve seats. The exhaust ports were smoothed and the ridges behind the valve seats were also removed like the intake ports and they were polished. The combustion chambers were smoothed and polished and I removed the machining ridges from around the valve seats. Pics are in my build thread.

Trackspeed engineering is working on a kit that includes this turbo. They are only supporting a 1.8 however.

Allegedly this turbo spools like a 2554 and is capable of 400+ rwhp.

It does spool quickly. When you punch it, the boost hits instantly.
