SPFI Conversion Manual

Featured Replies

Here is the legendary SPFI Conversion Manual write up (Single Port Fuel Inection = SPFI, a version of Electronic Fuel Injection (EF) also called Throttle Body Injection (TBI) by GM fellers :) ). This explains how to implement SPFI onto EA82 and EA81 Subaru engines. It was written by Kelly Huff who we are all indebted to for his effords in compiling this information. A big thanks goes out to all who have pioneered this conversion making it possible for the average do it yourself mechanic.

 

I would highly suggest downloading the .PDF document and keeping it yourself. While this domain and server I'm posting it on has been running since 1998; nothing lasts forever. I hope that it lives on indefinatly through people who have the passion to keep it and pass it on to all those who wish to undertake this proceedure.

 

Good luck and thank you.
