EFR comparison 8374 vs 7670
Geoff's pulls are the Blue ones, mine are in Red.
The big differences between Geoff's and my car is mine is a 2.2L and his is a 2.0L... and I have s3 cams and MIVEC... I believe Geoff has s2's?

What boost are you planning to run the EFR on when its all settled in? How is the transient response?

Mine is a top mount that I made for myself. Twin external MVS gates.
Geoff's has shorter runners (better)
Merge collector (same as mine...but a little shorter length/higher angle)
and he uses smaller diameter runners.
So Geoff's manifold will have better boost threshold than mine.
as far as commercially available manifolds for these turbos.. I REALLY like Geoff's Full-Race top mount setup he made for his own car for the IWG turbos. great manifold
