Those injectors have a really short body, they are definitely not the same as we use in the 2GR-FE.

Do you have room for a taller injector? something like this?

 

I want something that’s 500 or 600 cc and fits bolts on.

This is the closest I can find to your form factor. Available in 550cc.

I have searched everywhere and I couldn’t find any company that makes port injectors that’s fits bolts on to the 2GR-FSE engine.

As you may be aware those are the same as FR-S/BRZ/86 so I checked Deatschwerks and they do have some options however short nose.

Hello, in my search for port injectors for my 2ur-fse i found out that the ones in the 2gr-fse also fits. How did you find out that fa20 port injectors fit the 2gr-fse

Added a picture of the injectors i need to replace with bigger ones

 

Please post pictures of your 2GR-FSE. We love engine pron on this forum.

There are some similarities but they are not the same. I doubt they can be interchanged. I don't think either one can be interchanged with the one you pictured.

 

I have only changed the pistons to forged and rods ARP2000 but bore and compression is stock

Which pistons you are using ?

 

Hey mate, not sure how you’ve done on the injector upgrade but you have the same injector model in blue colour on LFA engines. They will flow a lot more since they only have port injection.
