well i got my car back from ricks rotary after installing my PFC and having it safe tuned... he told me he wasnt familiar with the safety of the Downpipe i have on my car for the street with stock injectors... he recommended me to put bigger injectors because he has dealt with plenty of cars in that stage... i dont plan on raising the boost as of yet... do you guys think i need to replace my injectors soon for the reliability of my car?? or am i safe for now?? any suggestions would be appreciated...

the mods are...
Engine rebuilt with 3mm apex seals
Efini turbos
Efini y-pipe
Greddy intake
Greddy pulley kit
Blitz FMIC
Koyo Radiator
Blitz BOV
PFC
Bonez Downpipe
Bonez Midpipe
Blitz Nur-spec Cat-back

Thanx,
Sean

 

ooops scratch that... he said he wasnt familiar with the safety of the "Midpipe" i have on my car with stock injectors... not the downpipe, sorry.... can anyone help me please?

 

You are fine w/ stock injectors to 12 psi. Some people say 13 psi but not recommended. Giving that the PFC is tuned for the entire mods you have currently. Just take into account that w/ a straight through exhaust boost spikes and creep can become an issue. W/out proper boost control your are walking a fine line.

 

i second the above post....but i also say get the injectors and crank that boost up!

 

You should definitely upgrade the injectors.

I'm quite sure Rick would have recommended sending off your injectors to be cleaned for the rebuild, why didn't you get them bored out then? Now you have to go through a lot of hassle and time to upgrade them.

You should also have ported the wastegate in the turbos to prevent boost creep. Your best bet now is to run a restrictor plate to maintain your target level.

Sorry if I sound harsh, it's just you could have planned things out a little better and saved yourself a lot of hassle.

 

take close monitor on the air fuel ratio.. get a wide band...
that will tell u if u need a new injector.

 

hey thanx for the help guys... well i actually bought the car after the original owner had the rebuild.. well i guess i should start investing in new injectors... anyone know where i can get a restrictor plate?

 

Well, if you have a Commander or the Datalogit, you can monitor your maximum injector duty cycle. If you're under 80% you should be okay.

 

How do you get you wastegates ported? Can you do it yourself? What good does it do? sorry still learning

 

If you search theres a write-up somewhere around here on it.

 

Do you have stock ports it sounds like? If thats the case and you can keep your boost down to around 12 you should be good for close to 300HP to the wheels and stock injectors.
