Good to hear that you are putting on a little larger turbo.
I will be most interested to hear how the .48 exh, 60 trim compressor T3 works out on your 1.6.
I can't remember what valvesprings you were using?
Standard Ford singles are good, but nowhere near enough pressure to allow 7800 rpm.
Anyone who has a 7000+ rpm standard Ford single spring 1.6, has a faulty rev counter
