Turbonetics ST
in all fairness, my car is a weekend warrior and stored winters (end of Nov through March). Last year I drove my car every chance I had and put just under 6000 miles on it. So 10-13K miles over a 2 year period is what I could consider normal for a non daily driver in my area.
In comparsion, my DD was driven just under 6500 miles last year.

I have about 10-13kmiles, driven normal 2 years boosted. I think the reason for me not having any issues is the tial 40mm wastegate along with open dumps. Like I said before. Powerlab is a superior kit but unfortunatly it wasn't avaliable when I was on the market for a single turbo kit.
I had one of the first Turbonetics kits on my '03 z33 (summer '05). The piping at the time in addition with free flowing exhausts (3" straight through single muffler designs, etc) caused the wastegate to fail and hence overboosting was present. This happened to my set up, as I was running the JiC DE Type 1 Ti (single muffler 3" exhaust) on my car. The gate's spring was 8psi, but it was allowing for 10.4psi to get through (405whp).
Turbonetics "fix" for this was to re-design part of the piping to put the wastegate in a different place and they sent out the fix to anyone who had the earlier kits. One of the drawbacks to implementing this fix was having to pull the turbo. Having so many projects, and so little time to work on our cars, we used an old Tial 35mm wastegate that we had laying around and replaced the inferior TN gate. This fixed the overboost issue. Therefore, it wasn't the placement of the piping, necessarily, that caused the overboosting, but rather their wastegate is inferior -- they just didn't want to admit it, and/or it was cheaper for them to make a couple of pipes.

ok guys i here alot of good and bad of the turbonetics kit i'm looking into the 350hp+ and was looking into the tuner kit cuz i have everything i need that the tuner doesn't have. i want a daily driver, so is the wastegate the only issue that came out of the turbonetics kit? I would appreciate the info. thanks.
