A few 3s-fte questions for the gurus.

[Percentage]

So, I was looking into turboing the 3s-fe and I still have a few unanswered questions.

1. Is running water lines to a ct-26 necessary? I know many other turbos don't need/have them.

2. Will an oil restrictor be necessary, or does the ct26 have one built in. If so what is a recommened size for a -3an line.

3. Will the flapper afm need to be run on the boost side in order for the car to idle. I know when turboing an NA nissan, this is necessary.

4. Can I utilize stock injectors at 6 psi of boost with an fmu? Also, what ratio FMU?

5. Finally in terms of ingnition timing, should it be 1/2* per 1psi of boost pressure?

thx for the help in advance.

I know you guys have turbo'd 3sfe's, any insight would be rockin'.

turbo life decreases if you dont have them on a turbo that was designed for it.

Will an oil restrictor be necessary, or does the ct26 have one built in. If so what is a recommened size for a -3an line.

-3AN is the size of the line, need of a restrictor depends on your oil pressure. I'm not using one on mine, just make sure your return line is BIG.

3. Will the flapper afm need to be run on the boost side in order for the car to idle. I know when turboing an NA nissan, this is necessary

It shouldnt make a difference on what side its on. However you cant use a atmospheric BOV after the flap and thats where most people make the mistake. Creating an air leak will cause the car to not run properly.

4. Can I utilize stock injectors at 6 psi of boost with an fmu? Also, what ratio FMU?

Probably, FMU is a bandaid solution. Maybe a 1.3:1 ratio.

5. Finally in terms of ingnition timing, should it be 1/2* per 1psi of boost pressure?

Good luck adjusting that without a standalone. I'd say start with 20degrees full timing
