Bell Engineering

For info regarding Bell Engineering (BEGI) kits. All prices are the base prices, BEGI is very flexible with adding or taking away stuff (adding megasquirt, powder coating, stainless steel, etc..). BEGi's prices range from about $1800 to over $3,500. They use a adjustable FPR (fuel pressure regulator) on the low end kits, and a choice of the Megasquirt ECU or Xede ECU for the higher end kits.

S Kit


Price:
~$1900
Power:
~150 hp at 6 psi
Years:
1990-2005

This is the basic BEGI turbo kit, sold for the 89-05 miatas. It runs at a modest 4 to 6 psi as it has no intercooler, and the only fuel management is a one of BEGI's FPRs. It is a very good base though, comes with a great cast manifold, and is easily upgradeable to S3 status. It comes with a Garrett 2554 ball bearing turbo, which can support a good amount of power with quick spool.
