i put T04S for my FD.. can i still run with stock injector and stock ECU?? can boost till how much? and am i need to change aftermarket apex seals?

 

*throws steven S D flame suit**
no no no, you will need to convert your car to single turbo and do all the supporting mods in order to be able to use that turbo. supporting mods would include fuel pump upgrade, injector upgrade and aftermarket ECU.
How much you can boost depends on your supporting mods

 

Wow.

 

You need to sell your FD quickly and immediately.

 

a lot of research to be done
ignition, fuel pump, bigger injectors, fpr, standalone ecu, tuning.

 

no kidding

 

1) You will need bigger fuel injectors. How big? Depends on how much boost. Probably 550x2 and 1600x2 is good for around 1 Bar (15 PSI) boost.

2) You will need an aftermarket ECU like the PowerFC

3) You will need the ECU to be TUNED with a wideband oxygen sensor

4) Stock apex seals are OK

5) You need an upgraded fuel pump

6) You might need an aftermarket fuel pressure regulator + aftermarket secondary fuel rails to run your larger injectors

Right now, you can boost 0. You will damage your engine for sure if you use boost like this.

 

intercooler

 

Um......in a word "NO"

You really need to either do one of two things:
1) Do your research about what is required to go single turbo. Start by reading the FAQs
2) Sell the car before you blow it up

 

That poor rx7... It never even stood a chance.

 

In fairness to the OP, he is in indonesia and I'm sure english isnt his first language.

I'd recommend finding some local smart rotary guys and go from there......
