Re: Anyone using this?
I did not use the fans McCoy uses and it created a little clearance issue with the upper pipe because the pipe near the fans was in slightly different place (I have flexalite fans). I had to cut my upper (near the turbo) in order for it to ling up properly which was my own doing for using a different fan anyways. The only part I had to really modify was bending the oil dipstick. The lower fits part no problem.
I have a PTE61 with a TO4E Compressor housing (3" inlet, 2" outlet) I am pretty sure it would fit the TO4S cover (4" Inlet, 2.5" outlet) with no problem, in fact my turbo outlet hose going into the IC pipe uses a 2 to 2.5" adapter.
