What everyone here is overlooking is that the fact that slides turbo is not a DIRECT swap.
The difference between a Japanese bush bearing turbo kit, slides and a gcg is as follows.
When i fitted my GCG... I had to change... ZERO (apart from the copper washers which is given) parts. Every bolt, every nut, everything just went back on.
The japs sell a turbo, they sell it in a kit. THey come with the dumps, elbows, bolts, washers, gaskets etc etc. These kits are 2000+. So the GCG looks more appealing now.
Slides turbo, from what ive read, there needs to be some modification to the oil and water lines and some of the banjo bolts (please correct me if im wrong). This *stress* COULD *stress* bring the cost up a bit. Additionally, *stress* MAY *stress* be overlooked by some people when installing the turbo, especially when its 2nd hand...
I am awaiting some results of tests....
