I know what everyones gonna say but im well aware of injector duty cycles and dangers and such... My question is simply will the stock fuel system work with a single turbo setup. The reason im asking is because i know you have to do the block off plates but im not sure if that stops the stock fpr from working.

the reason i ask is because i might be a little short on cash when i get around to putting my single in and want to know what my options are until i can afford the upgrade.

 

i'm running a to4s with stock fuel system other than a supra TT fuel pump...up to about 8-9 psi.

to keep the AF ratios under 12...i have to run about 90% fuel injector duty cycle.

so yes, it can be done.

I have the vacuum line straight to the fuel pressure regulator. Nothing is impacted by block off plates.

I have 1600cc injectors/etc in the bin...just haven't installed them yet

if you can only afford one or the other then its far better to ge the fuel first and turbo latter.

 

as long as your a/f is good then your ok. You'll prob be maxed to around 350ish rwhp but I dont know what that translates to in terms of boost for your turbo

thanks guys, thats exactly what i wanted to know... ill probably run around 8 psi until i can get the proper fuel upgrade
