Overview
Club member AFRacer built one of the first SR20 Turbo 1200s back in 2004-2005. He used an automatic-tunneled 1200 to make the fit easy.

Rear. Here's a pic from behind the engine in a automatic tunneled 1200. The coolant lines running behind the engine should be run elsewhere to allow more space behind the engine. Also the brake and fuel lines need to be redone from at least half way back so they're not inside the tranny tunnel
Left side. Plenty of room for headers, put a shield next to brake cylinder

Fuel System
The fuel system will consist of a high volume low pressure electric pump (Holley) sucking out of the gas tank into a surge tank, then the Walbro will suck out of the Surge Tank to the engine.
Walbro 255LPH inline fuel pump, high pressure for EFI and plenty of volume for high horsepower

Brake System
The SR swap only adds a few hundred lbs to the car, so it doesn't necessarily require bigger brakes. However you will likely be going faster, so it's a good idea to upgrade the brakes. Use a large diameter rotor to increase braking leverage while reducing pedal force needed -- the S13 Brakes swap is the easiest way.
