After about 3 months of buying parts, I finally have everything for my little big turbo install. I’m putting a turbo made by Corksport that’s based on a Mitsubishi 18g modified to bolt right into my Mazdaspeed3. I finally have everything I need for it.

The list:

  • Corksport electronic boost control solenoid (improve spooling and better support for >21 psi boost)
  • Bosh 3 bar map sensor (to support >21 psi boost)
  • Corksport 3.5” intake
  • Corksport turbo (basically a Mitsibishi 18g chra in a td05 housing made to fit the stock exhaust housing of my car)
  • eBay downpipe
  • Turbo oil in/out gaskets
  • All the hardware and hoses to make it all work

I”m going to tune it on 93 octane pump gas, these cars get a little weird when running different mixtures of e85 and full e has just only recently been made a more viable option on these cars, but I don’t really want to mess with it and the problems that can come with it. A lot of guys see their high pressure fuel pumps getting gummed up and it kills the gas gauge on the gen2 speed3’s. I already have all of the supporting mods, and will be replacing a couple things like the Cobb turbo inlet pipe and intake I already have. With these mods, I’m guessing I”ll be at anywhere from 340-360 whp. Right now, I’d say it makes 280-290whp on a good day on 21 psi. The stock block is pretty good up until you start getting over 400wtq, so I’m definitely going to keep the tune safe in that area.
