I have a stock 3rd gen 3sgte from a 96 jdm gt4 in my car and I'm thinking New cams, valves, head gasket, head studs, valve springs, and a port and polish. My car is a daily driver, so i don't want the reliability to got to s***. I also don't know if the power gain would be worth the money.

the vac in my car is at about 20 when everything is warmed up.
before i put in my mbc, i would get 10psi of boost and now i run about 14. there could be a lot of reasons why u didnt get more boost out of the box. you mechanic may have done something to the wastegate,you may have a restriction in your intake or exhasut, or a boost leak. hmm, what type fuel do you put in the car and are you getting any checkengine lights? sometimes when the ecu detects bad gas, or some type of engine problem it can put you into low boost mode for safety. read over all the BGBs over at celicatech.com and learn as much as you can about your motor. -------------------- 15PSI - 30MPG - Megasquirt Tuned

I think you got it. My car throws a check engine light for me being low on water in my intercooler, because I got rid of the top mount. I'm sure that is it. Well any idea on how to trick the ecu into thinking my intercooler is full. When I got my swap done they tried, but couldn't and I don't think they thought it was going to affect anything. So you think I should go up to 14 or 15psi, or should I go even higher?
