I paid $300 for my 89.6 crank and you can get that all day long. If you are going to spend over $1k whats another 30%?
Because there was no way I was going to drop $1k on pistons? I agree, if you are going with custom pistons or aftermarket rods and really building something than the 81mm crank doesn't make sense, there are known options that are better and with custom pistons you can get the desired CR for your application.
I however, bought my whole entire SETA bottom end for $80. I think for $80 it's a no brainer to just stroke it and use the 81mm crank then.

I think I might have similar goals as you, 77320i, in terms of making good power without blowing anything up orhaving to reinforce the front diff too much
Yea that makes a lot of sense and what I was in the middle of until there was an incident where my cat/downpipe section disappeared out of my garage. I couldn't find one online and anyone on R3V or E30Tech said they were willing to ship but then never responded back to me and nobody had anything local.
I looked into the cost of the kit and the price of the manifold and just thought, what the hell. May as well do it now while I can enjoy it and before I get hit by a bus, some moron takes me out, or I become senile and incontinent.
If you are doing that then I would say put in the cam for sure while you are in there, lighten the flywheel, buy ARP hardware for the head, rods, and mains, Total Seal gapless rings and then talk with VAC or someone about what bearings you should get to deal with turbo abuse. If you do that you'll be in a great shape for the turbo and since you are N/A it will be easier to load the engine and break it in without overloading it with boost so your rings will seal quite nicely.
There are a lot of people making good power on a formula similar to that.
