I have a couple of questions for anyone....<br><br>1) how can I get the turbo to SPOOL faster without spending an ungodly amount? <br><br>2) Has anyone tried to shimmy the wastegate AND also run the DP, cat-back, air intake ??? Has this caused Fuel cut problems???<br><br>3) I am looking for a DP, cat-back system and manual boost for a friend's supra....if anyone has these items and is looking to upgrade let me know...<br><br>4) Finally, has anyone done the above mods and kept the stock HG??? I have heard that replacing the HG, even with the stock toyota one is FAR better than the original one. My friend's MKIII had his HG replaced about 4 months ago. However, it is not a MHG nor does it have the ARP bolts or retorqued to 72 ft*lbs. Do people think running 11 PSI and lower would be a problem??? I have always been under the impression that running ABOVE 11 around the 13-15 PSI range requires a MHG, but that below this you really do not need it....comments ?? thoughts??? <br><br>thanks

I have done the above mods, and I felt the difference. I'm currently running 8psi. Switching to 11psi make the car so much sweeter to drive. <br>Running above 12 psi, make sure you have fuel( bigger injectors, fuel pressure reg, f-con or upgrade curve on computer.)
