Hi, would you need to change fuel injectors if you get CTR Pistons and put them into an ITR engine? Also, would you need to get your ECU Reprogrammed to handle the increased compression?

Thanks,
KJ

 

what cams r u using??
if you using some big cams, you should change injectors and reprogrammed ECU

 

You don't need to but it would be smart CTR's in a ITR motor will yield high compression numbers and knock with follow unless you have the proper fuel delievery.

 

yupyup
if you are using stock cams, i think just reprogrammed ecu or VAFC is ok

 

Yes, I'm using stock cams.

Do I need injectors? Or can I just increase fuel pressure and lean out the mixture where I have to with the V-AFC?

 

Just get a Fuel pressure regulator and VAFC should do it
i dun know whether you should lean out the mixture or not. But i want to know too since i want to get some toda pistons, i think if u lean out it will knock

The reason for getting the fuel pressure regulator is because the V-AFC can't really add fuel, so you use the fuel pressure regulator to make it RICH EVERYWHERE on the powerband and then use the V-AFC to lean it out where you need to.

 

are you planning to change cams?

 

No, I'm planning to sell my car so I'm only doing the pistons because I need new ones anyway.

 

KJ! U selling your car? How come? Thought you were going to keep it as a winter car?!

 

Hey man, long time no talk!

Message me on ICQ (I'm using a different computer now), I'll tell you the details. hehehe

Later man
