FRS-BRZ Port Fuel Injector (interesting) - Page 4 - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

I know that there are also different types of fuel injectors. What is best for each application? Whats the difference?

The DI injectors for all practical purposes will not need to be replaced and nor is it very easy. For more fuel focus on larger port injectors and fuel pumps.

On my car 900cc fuel injectors on E85 was only good for 400 whp running IDCs in the 90s on my personal FRS. Now I know everyone's dyno is different but this was on a dyno that baselines at 150 whp stock.

They are in the 220cc range from what I remember but they actually flow more in this application since fuel pressure is 55 psi.

Thanks! And one last question... Im thinking of getting an hks supercharger which would give me only 50 hp. I was wondering which injector cc should i upgrade to if i want to get another 50 hp?
Im sorry if this is a fucked up stupid question.... Im really trying to study about cars right now.

Has anyone tried to run PURE port injection and completely remove DI because of the seals going? Cause my seals went and I'm trying to see if anyone knows how to change settings using rom raider to ignore DI and i intend to just remove and weld the hole closed

Yes. Many people. Carolina Dyno has a thread about it.

And they sell a delete kit.

Use the search next time please. This thread is ancient and had no relevant information to the question you are asking.

You didn't even bother to search enough, and deleting it because of the DI seals failing is a stupid.
