Boost Brothers 3v Kit OR Why I need new pistons...
After reading post after post about "Chinese" or "off-brand" parts, I wanted to share my actual experiences with a turbo kit from eBay.
Earlier this year, I picked up a "Boost Brothers" turbo kit for my 08 GT. I only gave $1100 for it. The kit arrived, I unpacked it and was extremely impressed with the quality of the welds and the finish of all the parts.
I started to acquire some supporting mods....
60 lb/hr injectors
BBK fuel rails
Aeromotive Stealth fuel pump
Kenne Bell Boost-A-Pump
Glow Shift Wideband, Fuel Pressure, and Boost Gauges
Turbonetics manual boost control
I began the installation and shortly after became frustrated with the fit of the piping. It is tight to say the least and I was forced to make some minor changes to the y pipe from the exhaust manifolds to make it not hit the pipe that connects to the factory over axle pipes. Some fasteners were missing or the wrong size. Also, the kit requires the use of a factory exhaust hanger on the transmission crossmember that my car did not have, so more fabrication.
After 2 full weekends and 1 week of evenings after work, the kit was on. Keep in mind, I am an ASE certified master tech, and I was working on a lift in my fully stocked home shop. This was not over a week laying on my back on the driveway. I would have lost my mind trying to install this kit without the car on a lift.
I searched for a shop to tune the car and eventually decided to deal with Jeff Chambers at CRT Performance. He sent me an SCT Xcal3 with a start up tune. The car fired right up with the tune and I drove it for a couple of weeks on the start up tune with the boost turned down. I worked out a couple of bugs and then it was off to Norwalk to hit the dyno.
First, let me say that Jeff Chambers was probably the best part of this whole project. He was able to identify a problem with the placement of my MAF, sent me home to fix it, and rescheduled me for a week later instead of wasting my time and money trying to tune the car an underlying problem.
The next week, Jeff hooked me up. 470 hp, 490 ft-lbs, 11 psi on 93 octane and near factory driveablity out of boost. The car HAD amazing power in 3rd and 4th gear but it took a little long to spool for my liking. I am guessing the lag could be attributed to the generic "pt67" unknown specification turbo that came with the kit.
That was Saturday, 6/11/2011.
Yesterday, 6/13/2011, my evening ended with an expressway on-ramp, 11 psi, and a cloud of smoke. I was not far from home, so I limped the car back, positive I blew the oil seal in that cheap turbocharger.
Tonight, I removed the turbo and found some shaft play as well as oil everywhere in the hot and cold side piping.
Unfortunately, my findings didn't end there. I was low on coolant and found it in the crankcase oil. Also, I had codes for cylinder 1 and 3 misfires, so I pulled those plugs. Both plugs were soaked in watery oil.
I'm not sure what broke or how, but lets just say that you can check the oil with the dipstick through the no. 1 spark plug hole.
I'll keep everyone posted as I learn more......
