After a couple years wanting to do this swap, I have finally decided to go ahead with the build. I waited to see if i could locate a "C" OR "D" series engine but it was hard to find so i settled on a "B" series, I figure i shud be safe with a 10psi tune around 450-500 HP.
Parts List include:
Medium Street Ported 20B Engine
To be Rebuilt with Als Apex Seal and Stock Mazda Seals and Gaskets
FD3S Titanium Exhaust sleeves
Defined Autoworks Stock Subframe Kit
Defined Autoworks Shortened Lower Intake Manifold

Turbonetics GT-K 850 with a 0.96 AR exhaust housing
Tial 60 MM wastegate
Tial 50 MM Blow Off Valve
Thats Basically the Route I have Chosen to go, Any inputs and suggestions are welcomed.
Presently My 13b Single Turbo is out of the car, since no one appreciated the parts i had on this engine and didnt want to pay my asking price, I am having the engine transplanted into a First Gen.
Next step is to do a wire tuck and have the engine bay re painted while i wait on the subframe mounting to arrive from defined autoworks. Pictures to follow, estimated time for build approximately one year as i dont want to rush the project.
Nice!...good luck with the build!..keep us updated.
