Message: [QUOTE="Cold Roller, post: 892457, member: 9551"] Some of you know I built my own Stage 1 turbo a year ago and it ran very well on both stock injectors and 190/50s. I had intentions of building my own 2.5 or Stage 3 turbo, but I was still not sure of what turbine size I wanted to use, except it would need to be larger than stock or the turbo would not support the larger 67.8x94mm compressor wheel properly. Then along came Charlie (Peixinho) NOW KA KCTURBOS with his turbo. I was initially drawn to the simplicity of the insert he made for the compressor housing and the slightly larger, but higher flow turbine wheel. It arrived in early December and I wasted little time giving it a spin, really! The turbo came without a VGT, so I had to re-install my old one. So how does it run? [I][B][COLOR="Red"]I can say without a doubt that this turbo met or exceeded all of my expectation for operation.[/COLOR][/B][/I] :toast: It spools as fast as stock or my stage 1 did. There has been no surging or barking at all. Surprisingly, with the stock tune there is no smoke or haze with my 190/50s. With the Spartan Agg130 it was clean at WOT with slight hazing at the lower RPM under the turbo, less than my Stage 1 (my comparison to the old turbo result - this is the tune that used to give me the best mpg, empty or towing). There is a noticeable whistle at high idle and while driving at 1500-1800 RPM. The turbo and injector combination is pretty much smoke and haze free using any tune, even ones that are not the best for larger injectors. I have seen 40 psi boost on mid level and race tunes, including those from Wildman and Innovative. The race tunes showed lots of power, fairly low EGT (lower than what Charlie told me to expect), no smoke and no haze. However on one WOT run I saw vapour (white smoke at -25*C), coming out from under the truck. As it turns out, the degas was puking. It hasn't puked since, so I either have an impending problem or it was the cap malfunctioning. I have vacuum and pressure tested the system and it appears to be working correctly. I replaced the cap just so I can't blame it if it happens again. The turbo definitely helps create more power, but traction was somewhat limited due to the cold temperature. I was a little surprised the wheels broke loose at 55 mph on a punch. FWIW, I haven't seen a temperature over 1300..... yet Charlie asked me to take it apart for some photos to ensure there were no problems. I was a bit hesitant since it is working so well. I did take it apart today and I can confirm that all the big parts are in great shape. There was one minor casting/turning flaw that I fixed while it was apart. Charlie did offer to send me another housing either now or later if required. I have been running it for 2 month in total a few weeks since the inspection.

It will probably work with a stock truck and a race tune, but this would be overkill. It is great for my 190/50s:rockon: [/QUOTE]
