In your opinion what is the safest boost lvl for an EJ25 on stock internals if you want it to see 60-70K miles would 5psi of boost be woth it? If you have experience with running low boost on a stock EJ25 Please tell me abou it I am very interested.

If you do end up doing it the safest would be a standalone that is fully programmable and tuned professionally, by a conservative, well known tuner.

the safiest would be no boost, SUPPOSEDLY those pistons in the new age RSes are weaker, but that is just what I hear, Don't take my word for it, turbo it and tell us

Hush you know what I meant, the safest w/ boost...

Or you could just put some Nitrous on it

That's what I did... Zex Wet kit and now Turbokit & 92k miles on the motor so far

Only a couple bottles of Nitrous...

And like... 5k miles turbo'd w/ just a rrfpr and J&S safeguard...

Not Nitrous and Turbo at the same time...

And my point was that it was higher mileage when I started with the forced induction stuff

I have a TEC-3 sitting next to me now I just need to install it

Phase I block
110,000 miles total
20,000 miles on boost - 5.75 psi
10,000 miles with no intercooler
No piggybacks, no management: just an RRFPR 4:1, and 93 octane gas.
**no problems**

Just took her apart, getting it bored out +20 and putting forged pistons in. Block looks brand spankin' new. No cylinder wall warpage or scoring or damage of any kind. No head warpage, no piston shadowing on the cylinders. No signs of detonation or oil burning.

Little bit of wear on the top surface of the head gasket, replacing those while I'm at it.

So, yeah it CAN be done, but then again, you're running a higher compression, so hey.

Try it out! The difference will be like night and day. No...that's a bad description. The difference is like a remote controlled airplane and a 747, especially with a bottle warmer.
