Definitely. Once I get this thing sorted, I will be going back to them. Brian and I talked quite a bit. Dude knows his stuff. It's nice to have someone explain things as we go. 


As it sits, I'm looking at 3 options.


1. Replace my CHRA with a 35R

2. Replace my CHRA with a GTX35R

3. Buy one of Turblown's TD61 or TDX61's and weld a T4 flange on my manifold.


Obviously, 1 & 2 are easiest. I can do it all myself and likely head back next weekend as scheduled. 3 is definitely the more desirable and definitely more power yielding. Welding the T4 flange on my manifold while still using the rest of my kit will require more skill than I posses. That means dropping my car off at Daves, and letting them fab it up. 


#2 seems like it would be an upgrade, but I don't know how the small turbine and T3 will do with an upgraded compressor. I have yet to see a lot of results from the GTX setups on a T3.


I'm really torn... I PM'd Turblown for some insight. We shall see.

I'm feeling pretty retarded right now. 


I looked at my core and piping and everything is clear and clean. So after reading Ben's post, I decided to pull the waste-gate and look it over. BINGO!! After disassembling the waste-gate it was apparent that it easily stuck open. Carbon was badly built up around the upper part of the shaft making it stick in the open position. The shaft slid but it wasn't smooth at all. I cleaned it with carb cleaner and scrubbed it down. It glides like butter now! I also noticed a large gash in my diaphragm on the sealing side. 


Tomorrow I will be calling Tial to get a new diaphragm, and swap my 12lb spring for a 15lb spring. I am pretty convinced that this was my problem the whole time. There is no telling how long it's been like this. It may have been working extra hard for the 15lbs when I originally installed it. I feel pretty stupid for not checking its operation and diaphragm condition during the new engine swap. I guess I overlooked it due to no apparent issues and only having a few days to get everything swapped over. Live and learn I guess.


As far as my turbo, I am still on the fence. Turblown mentioned, like my advice here, that there is nothing majorly wrong, but a new CHRA will be in the cards. I'm not sure if my overspooling damaged it or it will live on for awhile. I have yet to decide. Either way, his price on a replacement was unbeatable. 


I am calling Tial tomorrow
