Garm, I respect you on this site for your contributions so I won't be disrespectful to you like I would, say Poopy Peter or somebody else as stupid. But, on this subject I think you and anyone who thinks like you are just flat wrong. Spreading the message that adding forced induction without proper engine management to ANY car is ridiculous within itself, not to mention the fact that you're doing it on a car with a 10.5CR (or whatever it is) that was designed for fuel economy. I mean, at the VERY LEAST I would recommend at least doing a rising rate FMU and a map/maf clamp but even that is still a recipe for disaster in the long term. Just because you got away with it for "almost a year" doesn't make it safe. There are kids on this site that don't know any better and if they read a post that says "you can boost your Yaris to 7psi without any engine management" they'll go do it, blow their motors and come back and blame you instead of their own retardness. Boosting a N/A motor is hard enough with the proper components...but slapping on a turbo with no supporting mods? What about the effects on ignition timing? A/F ratio? Fuel pressure? EGT's? It goes on and on...

I'm all for doing stupid shit, but I draw the line when I see people (especially someone so key on this site like you) recommending to other people to do stupid shit.

can't do a rising rate


this is a returnless fuel system buddy ;)

buy a wideband, put in some larger injectors, and go to town. the car will take care of timing at 7psi.
