For anyone who has done the V-6 swap using a 164 motor, what is required to install a late-version front-mounted 2.5 distributor? Do they use the existing drive gear that runs the 164's oil pump (and keep that pump), or is there a different drive shaft/gear required? does this distributor integrate into the 164's wiring harness and ECU without alterations?

You need to use the GTV6 oil pump because it has the top end slot to drive the distributor. Otherwise forget to use the 164 harness and just use the GTV6 L-Jet electronics. That means that you must also transfer the GTV6 plenum and injectors to the 3L 164 engine. As you cannot use the 164 flywheel you will have to check the balance of the 164 flywheel and adjust the GTV6 flywheel to the same balance. Also you will need a 4mm spacer between 164 crank and gtv6 flywheel. If you are interested in 3L power you should discard the iron exhaust manifolds and rather use tubular headers as the cast iron robs about 15Hp. Also for a revving engine would recommend the QV cams on the 3L, brings about 7-8Hp. Just about it. If you go for an ECU even more power will be gained, then discarding the restrictive airflowmeter.
