Stock rods usually break or bend before stock pistons.
You will want some way to tune the timing on the car. Raising the compression from 7.8:1 or lower(worn motor) to 8.5:1 or higher after deck/head milling usually turns the car into a detonation machine with the stock ECU and the boost levels we normally run on pump gas.

Well John and I both thought he said forged pistons on 1g rods.
The factory mitsu pistons are much weaker than the rods, so he should be just fine on 1g rods. I am just not a fan on spending money on used rods w/o replacing everything that is serviceable on them.

Where?
I am fitting some 2g pistons on some 1g rods.

I don't know. For some reason I thought he was saying forged pistons. The last time someone asked about using a stock mitsu piston was so long ago...:angryfire:
Whatever. I don't really see the point of even bothering to put 2g pistons on 1g rods. If your stock motor is good, use it. If your stock motor isn't good, go with forged internals.
This isn't like the 3000gt's where the only rod option that is worth a shit is $1100
All that being said, Andrew...any machine shop with 1/2 a brain can follow the instructions on vfaq.com. I would shop around. I personally do not use the carquests, napa's, and red roosters for anything more than just flywheel machining (and that is rarely) as I have seen my fair share of mess-ups from "machine operators" at parts stores.

I've got a 4 bolt rear end if your interested

I might be interested in the 4 bolt!
I am going to use a standalone aftermarket computer on the car so it can run comfortably on the 8:5 compression.
The engine needs some freshing up. The motor right now is burning (or leaking) oil right now and I just want to do a simple rebuild just so I know it is fresh. I think I am even low in compression in a cylinder somewhere so new rings wouldn't hurt. I even have ARP head studs that I want to install. I haven't put my car on the dyno in fear of being laughed at because it will have black smoke at WOT.
I am not rich so I can't afford Forged internals and if I were to do so, it wouldn't be on this car right now.
I did find the vfaq machining data so I am set there. So back to the main point of the thread where would people recomend doing the 1g rod 2g combo
I will check out the place near the university. I am close to there anyway.

I would do a comp/leak down test, and some base line dyno numbers to see where you are at and where you want/need to go.
