This is what my rebuilt 6-bolt consists of

This thread is pretty rediculous overall. The same info was asked and answered on the old engines demise in the other thread. using the 7 bolt front case/pump on a 6 bolt requires modification and use of the 7 bolt pan etc, all so you can run the crank sensor. We don't do it simply because we havn't had a problem with the random misfire issue on any of the 6 bolt swaps we have done without DSMLink and until there is a problem for us using the 1G CAS, that is the method we will continue to use. This thread needs to die.

You didn't use a 1g cas? Why wouldn't you just use a 1g cas. I have never heard of anyone swapping a 6 bolt in and using the 2g cam and crank sensors. Why did he need to modify the front case other than the bs elim?
The 2g crank trigger is much better than the 1g setup.In the 1gs, spark is triggered off the cam, and as the timing belt stretches at high RPMs, it throws off the calculated ignition advance.Spark triggered off the crank position sensor(as it is in 2gs) is a much more accurate way.

EDIT:I'm pretty sure its the timing belt thats causes the random misfire code as well
