By responsive, you mean less lag? Probably due to a smaller
turbine. Inconel 713C is standard.

Always go with the manufacturer recommendation or an exact
replacement. Peugeot recommends for the 86 turbo: Bosch WR7DS or W7DTC.
I dont think the NGK BP6ET correspond fully to a W7DTC.
On the Lancia I also had went with some platinum (NGK) and
when I went and put some Lodge Golden HL (at George Nunez
suggestion) I immediately felt it.
