$1000 is not much - how do you like the performance gains?

Interested in any info you have to share - this could be my next project.

Thanks for posting.

Currently have my wastegate set to 3psi so power gains are not significant. Will be installing a heavier spring in the next few days (6psi) and will give an update. Feel free to send me a message about any specific questions you may have. I couldn’t pass up the opportunity to have boost for $1000 but the time spent fabricating was significant so that is a consideration if you have the tools available to DIY. Having a shop fabricate the parts needed would get expensive fast.

Update:
Scavenge pump was leaking from front most compression fitting. Got that sealed up and reinstalled, then went ahead and threw in the 6lb wastegate spring. I’m not sure if the spring ratings are inaccurate (ebay wastegate) or if I have reached the max boost with this turbo for the diameter of charge pipe (2”) I am now seeing around 4.5 - 5 psi max but do not hear the wastegate open. The power is definitely more noticeable at 5psi and I will more than likely keep it in this range as my AFR’s are happy and no CEL as of yet. For reference my turbo is an ebay special, T3/T4 .5 compressor AR .63 turbine AR
