not sure what the use for all those lines are for. when I turbo a car i try to use as few T's as possible.
i dont know what ECU he used, I used a Split Second when I did Eryns car. could never get the tune right. I used an AEM FIC on my car when i had the 5S turboed. It fought with the stock ECU all the time. I suggest a stand alone to do it right. maybe a megasquirt or Link. to keep costs low. -------------------- 2001 Celica GT-S Turbo

Hose with 6 check valves = to bleed off boost so the MAP sensor/ECU doesn't freak the hell out. The OEM MAP sensor you have is not capable of "reading boost", it can only do vacuum to -25psi or so and up towards what is known as "atmospheric pressure", which is often erroneously displayed as "0psi". Normal atmospheric pressure is 1bar / 14.7psi (at sea level), so the "0psi" on your boost/vacuum gauge is actually 14.7 psi. When I decided to force-feed my lazy 5S-FE, I choose to use a 3S-GTE MAP sensor and larger injectors (MK3 Supra NA 315cc injectors part #23250-70080, double check this part number for accuracy) with the OEM 5S-FE ECU and an upgraded 255lph fuel pump. No need to screw around with a bunch of check-valves to bleed boost pressure from reaching the MAP sensor. Which is just about the simplest way you can deal with boosting this engine. I wonder if the 7A-FE engine can deal with a similar setup using a MAP sensor from a turbocharged engine... -------------------- Toyo'd, Eibach'd, Kayaba'd & BEAMS'd :D
