"procams do require additional valve train upgrades"

this was not directly mentioned or aimed at the rb motors

Thus meaning if you run hydraulic lifters the procams will kick the shit out of them so you will need to upgrade to solid

additional parts for the rb26 solid would possibly mean thicker/ thinner shims to compensate for the different base circle thicknesses

how do i know this? Cause i work at a machine shop and i actually have hands on experience not 2nd hand.

But if you believe you do need to go Tomei lifters in a 26 don't let me stop you

* Adjust Shims may be required for some models.

* Tomei Lifters are required for MID, HI, SUPER HI types.

* Uprated Valve Springs are also required for MID, HI, SUPER HI types.

Mid = 10.25, High = 10.8 and super high = 11.5. All of which are "Procams"

Straight off the Tomei website.

They have a smaller base circle. Thats like buying a 18 inch tyre and trying to fit it on a 19 inch rim.

I spose if you want to run a huge shim then yeah, it would work.
