And some turbo pictars
Posted: Jun 11, 2007 3:18 PM
I've been trying to post these suckers for a while now, and I just got them to work today.
This is the GT2871R (left) and GT2560R (right) from the turbine side. This is the reason why I felt the need for a larger turbo. The GT2871 has a .86 AR housing around a nine blade 53.8mm, 76 trim wheel. The GT2560 has a .64 AR housing around an eleven blade 53mm, 64 trim wheel. The GT2560 turbine can flow about 14lbs/min at best, while the GT2871 can do 21lbs/min. The rest goes out the wastegate. The difference was a 1000 rpm higher boost threshold on the GT2871R at about 3k rpm and a big gain from 4k all the way up to 6k.
This is the 2871 and 2560 from the compressor side. The 2560 compressor is ideally suited to my engine, but the turbine is too small. The 2871 compressor is a bit large, but the turbine is better suited. Its the best off-the-shelf turbo for the 2.7i and turbodiesel manifold combo. The 2871 has a 51.2mm inducer and a 71mm exducer diameter. Its a mean looking wheel, especially with the compressor housing off. The 2560 has a 46.5mm inducer and a 60mm exducer diameter. The 2650 was much louder. It really screamed when it spooled up. The 2871 is still audible, but much less alarming. Also, the 2871 can be fitted with a GT28RS style WG actuator, allowing for universal compressor orientation. I had to modify my 2560 to blow in the right direction. The 2871 compressor and turbine share the same flanges as the 2560, so the swap was a bolt in operation. Damn nice, I say.
This is the configuration as of June 2007. Major updates include a Split Second MAF and a load of duct tape around the bellows to keep it from blowing up. You can't see it, but its also got a set of 19lb injectors and a different chip with a little more timing advance. It's waiting on a stronger clutch and some cooler plugs, then I'll see if I can turn up the boostage once again.
Thats the car. No front valance, no bumper covers, no hood roundel. The drivers door is missing the bumper strip, and it slightly misaligned. The bondo on the passenger rear door is cracking, as well as the bondo on the drivers side upper c pillar. Its a total peice of shit.
The rear is still showing the damage from the accident a few months ago. A spare tail light bolted on, but doesn't fit or seal against the body.
