I still haven't put mine together yet. The Eaton still sits in a box in the shop. I'm planning on putting it together this summer though. I'm just going to use an FMU instead of an extra injector setup. I'm only planning on running around 6 psi. It should be pretty fun! I found someone on Ebay that reconditions the Eatons (bearings, drive coupler, new oil and seals, bypass) and the price is decent. He wants $400 exchange or $550 if you don't have a core. That's slightly lower than Magnuson which is around $700-800 bucks. I'm thinking of doing that instead of installing my used one so that I won't have to worry about putting a used part on my low mileage engine. I figure $400 for a rebuilt blower (since I have a core), $220 for an FMU from Flying Miata, Then around $100 for the tensioner and related parts, then $50 or so for the new belt and steel parts to make a new alternator mount, then I'm hoping to keep the manifold under $250. If it all works out, I hope to have it together by August.
