i have a darton sleeved ls/vtec, 84.5mm pistons, sc61 to4s cover, and my question is, i plan on running a 2 stage boost controller low pressure @ 14 and high @20-22 or more?? i plan on running a 38mm tail on my mini-me and wondered at these boost levels are you guys runnin the high pressure wastegate or the standard one. thanks in advance

 

You want at least a 0.7bar to 1.0bar spring.

 

im sorry i was under the impression that there were two different wastegates high and low pressure, i know i can switch out the springs but can i put a one bar spring in a low pressure wastegate?????????

 

The HP wastegate is over 1.0bar. They basically use 2 springs such as a 1.0bar spring and 0.5bar spring to make a 1.5bar HP wastegate.

 

Thanks for the clarification

 

Anytime.
