RB26 ITBs too small!

[DEFIANT 7M]

I'm just going to jump in here running. My itbs 45mm are to small too feed this monster. I need 55mm yes I said it. I may have to bore these and keep it moving. What car has 55mm itbs? Not really fond of the idea that these may by one of those 'damn I $crewed up.' I know I can go Kinsler but my gawd thats a lot of money.

Cams north of 300 duration and further north of 11mm lift than ever spoken in any sentence I've read in regards to a 7M.

And this is why the OEM engine designers use a plenum intake, it allows each cylinder to see the full flow from one large throttle body.

The original stock EFI 5.0 Mustang (4.9) had a 55. The 87 then came with a 60mm. The year of the 55 is the 86. There should be a bunch of them somewhere as many went to 65mm.
