can somebody tell me what the differance is between a 6k and 7k ecu,
and will a 7k sti ra ecu be ok in a sti

thanks matt

 

Ive got a 6k ecu in my v2 sti which has a rev limit of 7000 rpm, the heads have been removed and on inspection I found they had hydrualic tappets.

I am not sure if the sti ra has solid tappets in the heads, if they do I suppose the rev limit would be slightly higher.

What car do you have?

 

I'va a 6K in my V2 STI too.

 

I thought the v2 sti redlined at 8,250?

 

I think it was the version 3 onwards that redlined at 8250rpm.

 

a sti 2 but its got a z4 in it
