Are STi injectors top feed?
INJECTOR DYNAMICS ID1300 Compatible with STi 04-06 / Turbo. Note: All Injector Dynamics injectors are top feed.
Are stock STi injectors side feed?
06-07 STI injectors are NOT side feed. And they are identical to 06-07 WRX and FXT injectors.
What is the difference between top feed and side feed injectors?
A top feed injector receives it’s fuel from the top of the injector, where the injector top plugs into a fuel rail. The side feed injector receives it’s fuel from the side of the injector, where the injector is nested in a fuel rail.
What is side feed?
Side feed injectors (like the STi’s) get pumped fuel into slots on their side and top feed injectors get pumped fuel through the top of the injector. To change from side to top feed you will need to change your fuel rails.
What is injector dead time?
These all have the same definition. Fuel injector dead time along with the other 4 definitions is the amount of time it takes the fuel injector to go from open to close. Voltage is what causes the Injectors to open/close, and depending on the amount of voltage, the injector can open faster or slower.
What are pink injectors?
The 565cc “pink” injectors are high-performance injectors for Subaru found on the high horsepower STI, STI-RA, and S202 Impreza models. Fit Denso Pink STI 565cc Fuel Injectors. Fuel Injectors 16611-AA370 16611AA370. For Impreza WRX Forester GDA GDB VF30 VF34.
How do side feed injectors work?
For side feed injectors the fuel enters through slots machined into the sides of the injector. The fuel rail is combined into the inlet manifold or cylinder head. Top feed injectors: As the name suggest fuel feeds into the injector from the top.
How important are injector dead times?
Having accurate injector dead time settings (also known as injector lag time or latency) is critical for a quality idle as well as maintaining air/fuel ratios when there are lots of accessory loads on the engine (ie: headlights, heater, etc.).
What CC are pink injectors?
This page http://users.erols.com/srweiss/tableifc.htm says that they are 231cc at 3.0 bar pressure…
How many cc are STI Pink injectors?
565cc
The 565cc “pink” injectors are high-performance injectors for Subaru found on the high horsepower STI, STI-RA, and S202 Impreza models. These injectors are factory rated at 525cc but because of the common “under-rating” system of Japanese manufacturers, these injectors have been independently tested to flow 565cc.
How are fuel injectors fed fuel?
Side feed fuel injectors are injectors where the injector body is surrounded by fuel. The fuel is fed through a hole or holes in the side of the fuel injector. This category can again be sub divided into two groups: throttle body and manifold.
What’s the difference between side feed and top feed injectors?
Side feed injectors (like the STi’s) get pumped fuel into slots on their side and top feed injectors get pumped fuel through the top of the injector. To change from side to top feed you will need to change your fuel rails. I don’t know if there is a performance benefit to one over the other.
Can you change the STI over to top feeds?
If you try and change the STI over to top feeds, you may have to wire in WRX connectors so you can plug them into the engine harness. The TGV injector “seats” are also different. You would have to source WRX TGVs or APS TGV deletes specifically for the WRX.
Which is better top feed or side feed?
So going with top feed (such as the 860’s helix injectors) why would it be better (or not better) to go with say, the sard side feed 850’s? I take it I’d need extra parts to install top feeds on my car?
Can a WRX be used as a top feed?
I only mentioned the WRX because it uses top feed injectors and would have the correct injector connectors for the top feeds. If you try and change the STI over to top feeds, you may have to wire in WRX connectors so you can plug them into the engine harness. The TGV injector “seats” are also different.
