Does anyone think or know if i need to upgrade my injectors for the TD04 or will the stock pinks be fine?

You dont need to unless you are going over stock boost or if you have engine management.The stock ECU is reported by many to run 440's fine.If all your doing is putting the TD04 on and not really changing anything else then there is really no point.

I wouldn't be so sure about that... at least the data logging I did with my TD05 at ~11.5 PSI, was already maxing out the stock injectors and MAF.

Yup,and that would pertain to the exeption i pointed out in my post "unless you are going over stock boost or if you have engine management"

.Some people just want to run stock boost with a supposedly more efficient turbo.In which case there is no need for bigger injectors when no more than stock boost is used.And im sure 9-10 psi would be just fine.Not to mention that all our cars are a little different.

That'll last all of 1 week before they're itching to turn up the boost

FYI I ran a TD-04 and TMIC on stock everything for a while before the Revtronix chip came out.

I was fine up to 11psi, the TD-04 doesn't flow too much more than the VF-11. Also, I did not notice much of a difference between 9psi and 11psi.

I am at 5000', which does make a difference.

Yes if you get na rails those will fit. I bought mine from him a few years back. I ran those with a vf39 up to 18-20 psi. Then my transmission exploded.

You WILL need a lil' computer to pull fuel at anything below 14 psi. I run my vf39 at .9 bar on stock ems and fuel injectors now. My wideband says that's I'm ok in that deptartment.

Those look just like the ones that I pulled off a Legacy EJ20G motor, that flow-tested at 440 and 444cc.

Mine fit in the 1991 EJ22T rails just fine.
