alvin, no need extra injectors and controller for it lar, ur blowing it out of proportion
you already stated you need to change ur regulator (i suggest pump too), injector and afc, thats more than enough to provide fueling when boosting. just change to an injector thats big enough, i guess at <0.7bar with maybe a td04 can use gsr's 390cc injectors. maybe can cut price down further by just rechipping, having someone to make a modified chip to replace the afc
the thing that would probably cost alot would be the exhaust manifold since it'll need to be custom made
stay low boost, put nice bov, give enough fuel and be content with it. if ppl wanna race with u just think about the petrol prices (which will rise again yippee). shouldn't cost alot that way :lol: all u need is discipline good luck!
dolly...
not enuff.. really... need the extra injector... i've said it again i'll say it once more... its because of the n/a ECU can't detect boost... so at high boost the engine runs lean.
Fuel regulator + SAFC + stronger fuel pump + larger injectors... all won't help you. Tested and proven. GSR injectors are TOO BIG... you'll kill your O2 sensors running on them!
The ONLY way is extra injector + injector controller.... even with emanage or whut ever after market piggy back ECU also won't help you... coz' n/a ECU doesn't support boost sensor! (standalone... now thats a whole new different story!)
You can't just set your fueling according to RPM and hope for the best... it doesn't work that way with turbo. AT different RPMs, different throttle positions, different boost, all will require different fueling. An n/a ECU supports the adjustments according to RPM and throttle position... but doesn't know how to detect boost....
The extra injector + AIC is to conpensate more fuel while your turbine is building up pressure (boosting)... the AIC comes with boost sensors, so they can detect how much boost you're running on and release the appropriate amounts of fuel thru your extra injectors... (according to your settings that is).
Hope these info helps u to understand better.
