upto how much psi can greddy kit or apexi kit can push?

As much as you want it to.

I know Greddy comes at 5.5 and can be adjusted to 7 or something, but it will take 15 maximum after you put more $$$ into the kit.

15 max??? I was told that that was pushing it, I was told like I think 8 max, but I could have been told wrong, I dont know.

you can run 20 on the greddy kit... i dont know why people say its only 15...

You can go as high as 20-25lb on either one of these kits, but you have gone past the efficiency range..meaning you are not making any power due to significant backpressure. I would, however, say that the Greddy will do fine up to 12 and the Apexi IHI turbo can handle a bit more and still be within optimal efficiency. Both are great turbos, which I wished I would have purchased instead of the crappy Turbonetics that I have now.

Ive heard a stock sohc motor can handle upto 10psi daily drivin, and upto 16psi on the track . . . feel free to correct me if ive heard wrong . .

i have a greddy kit for my z6. the bottom end is rebuilt. before it goes in it will have hondata, dsm 450cc, stock 2" dp for now, 3" dp back exhaust w/ no cat. 1st gen dsm smic...and like 2" pipes from turbo to intake manifold. i am going ot have it set at 10psi. i hope all this stuff tuned on a dyno will be a good, fast, reliable swap.

more like... 8 daily, 10-12 track.... 12 is really pushing it... but there is someone running 16 on stock internals makin 300+whp.... but that is crazy... and it will blow
