I've built and installed a MegaSquirt EFI system controlling a Chevy throttle body injection (TBI) setup. The turbo is hanging back by the transmission and hooks up to a custom exhaust using two rear EFI manifolds from a 90s F150 4.9. It's still a work in progress, but coming along nicely.
I'm still finishing up body work while slowly putting together the turbo setup, and still a few weeks away (at least) from getting it driveable. It's been an interesting challenge so far. I'm hopeful that 7-8 pounds of boost from the little Subaru WRX turbo will really wake up the 240 -- although it already ran fine on the old single barrel carb.
The turbo hangs back by the transmission and is supported by a fixed hanger attached to the transmission and a flexible hanger bolted to the bed floor. The tiny intercooler is horizontal to the air flow under the truck, and I'm not sure how much cooling it will provide, but probably better than nothing.
Right now the turbo is drawing air through a cone filter above the intercooler next to the bed floor. I'm still debating whether I should route a pipe to the front of the truck or just leave it there.
The intake pipe is routed between the headers. I plan to wrap the headers to help reduce heat in the doghouse and also keep the intake air a little cooler.
I build a custom intake plenum to direct air into the TBI. It easily fits inside the doghouse.
