i am wondering how much boost would be too much boost with the stock valve springs, and what is the rating on the stock springs? im getting an II 64mm turbo, 100hp injectors, airdog 150, and i already have the edge ez.

thank you in advance!

 

I have about the same set up and push 48psi max on stock springs running about 3800 rpm no issues here but i think anything over 50psi would need springs and push rods.I've got them but haven't found the time or need to put them in! I'll wait till I blow a head gasket or eat another piston!

 

thanks for the info, i ran acrost a website yesterday and they had me thinking because they changed the turbo then springs and then injectors...
