Replacement Rotrex Supercharger for the GTM Stage 1 kit

Infidel

From the site for a Stage 1 SC:



The GTM Supercharger kit has two different Rotrex compressors to chose from: the C38-81 trim and the C38-91. Combined with our custom compressor housing we will offer three different stages .

Stage zero up to 450 HP (CARB approval in progress)
Stage one up to 500 HP
Stage two up to 550 HP

Also from the site:

We are pleased to announce the GTM Stage 1.5 Supercharger Kit for the 370Z. The Stage 1.5 uses the same supercharger head unit as our Stage 1 Kit (the Rotrex C38-81) with the intake system of our Stage 2 Kit

How much do they want to rebuild the unit?

Thanks for the reply. I saw that on GTM's page. I still need to know the correct trim, C38-81 or C38-91.

From what I find online, the units are not rebuildable. There is an online vendor who advertises rebuilds but if I stay FI, I will just purchase a new unit.

My money is on the 81, just call GTM. It's hard to believe the Rotrex isn't rebuildable.

ETA...Sure enough, went on Rotrex's website and they can't be rebuilt. Score one more for Turbo set-ups
