turbo and converter matching?

[turbo96max]

I have an 86 gn that im replacing the engine on. I have a set of ported irons with 177/150 stainless valves ported and polished. a 210-205 cam, and for now a pt54 with 42.5 injectors. The car has a 3800 stall westcoasts converter that felt tight more like a 3400 but nevertheless when purchased was supposed to be a 3600-3800 stall 10 inch non locking.The converter is like new but I was thinkig about getting it restalled. I will be going with a 6175 or 6775 turbo as the last upgrade. The car is a daily driven car, so i want to find a middle ground btw performance and gas efficiency. i was thinking lik a 2800-3000 stall, once i get some injectors and the upgraded turbo, how well will a 2800-3000 stall converter spool up he 61 0r 67 considering it will be a full ball bearing turbo??

I would go with the 67 bb and a set of 60's if you plan on staying on the street, if not then a set of 72's.......

What chip do you have?

If no TurboTweak then.....Turbotweak

I will be staying on the street, and i am leaning towards the 67 bb, i need to get the alky kit, and i was actually thinking about changing the setup back to lock up.the previous owner had it set up for non lockup? is tha a bad idea? either way what stall you think would be good?

Not sure...I would check with one of the trans guys to be sure...may be a answer in the trans section.

I have been asking plenty of convertor questions for my PT6776, but mines a journal bearing. Of what Ive been told, you would need @3200 for the BB turbo67, and 34-3500 for a journal.

I would normally run a lockup converter on the street, but for track a non-lockup is ok.....a non-lockup is going to spin the engine about 100 rpms more.....a 3400 stall would be about max I would go.....
