Holset knowledge needed

No. The grill just barely fits. I did lose two of the bottom mounting screw holes due to trimming but there are plenty left to hold it in place. The intercooler is 2.5" anything larger would not have fit. I just got lucky on my calculations for size. I did however have to reduce intercooler piping from 2.75 to 2.5 as it passes into the intercooler and vice versa coming out. The throttle body is 3.25 and the Holset is 3.0 so it's been a hodge podge of a mess to get to his point.

The radiator cross support had to be hacked pretty hard since it protruded in over an inch. It will need replaced with a piece of flat stock and welded back in place.

I also lost my center hood latch in the fitting process due to size constraints. I will have to weld some gussets on the fenders and use thos pop in and out hood latches that are so damn expensive.

And I have two spal 12 inch fans mounted in a stagger with a homemade shroud and my water pump clears by less than a quarter of an inch.

I have learned these early A's are a whole different animal than the later ones.
