My brother bought a supercharger kit recently and he's wanting to start w/ less boost than the kit was setup for, also came with a tdr intercooler but we're thinking if we can get a crossover tube for cheap we'll do that with smaller pulleys. (TDR intercooler kit is a time consuming install) The problem is the car is 1.8 swapped and has a new oe style clutch and the factory open 1.6 diff, and this JDM 1.8 seems to be burning some oil so he's wanting to do it more in stages.

 

You would want a larger SC pulley for less boost.

 

I was thinking smaller crank pulley, but whatever works.

Here's what he has, https://www.miataturbo.net/miata-parts-sale-trade-5/fs-brp-superchrager-kit-extras-53032/

 

Let me see if I still have my old crossover tube. If so you can have it for the shipping cost. Give me a day or two.

 

That'd be awesome, thanks for the help.

 

Bump.
