engine rebuild

what's the going rate or cost to rebuild an 86 GN motor

That's a difficult question to answer without a few details. How much power are you looking to get out of it? What condition are your parts and are you going to reuse them? It's very easy to spend a lot of money on a rebuild. You also will want to find someone close to you that know's how to do these motors correctly. They are not like SBC's and many places mess them up.

4,000-15,000

Yep, it all adds up quick. You are not getting out of a solid stock rebuild for under 4K. Start getting fancy with forged rotating assemblies, girdles, roller cams and you can easily double or triple the price.

 

[Boost231]

should have put 15,000+

Your looking in parts alone $4,500, turbo, pistons kit, rods, crank all forged, roller cam kit etc... for moderate build and another 3,500 machine shop cost and install labor. I have mine being done at the moment. Total about 7-8k for a decent build

I had machine shop do all the work to my block, rods, pistons and heads. Turned crank, line bored, honed and magnafluxed the block, resized the rods, decked the block and heads, installed new seals and magnafluxed the heads, I put the motor back together with a hydraulic cam and stock rockers. Also with a full gasket kit I have 1800 or little more in my motor. But all of my parts were good except crank needing to be turned. I just wanted a pretty much stock rebuild not a whole lot of power. Like mentioned above depends on how much power you want and your goals. Doing a lot of the work yourself saves some money.

Seems really expensive, what's the weak link in these motors? What can an unopened motor make hp wise before its at its limits?

Usually the idiot mashing the gas.

Well let's see. The crank is cast and flexes, the block is a light weight casting and flexes, but the rods are ok though.

Some have made it into the low 10's on a "stock" short block but they didn't hold on that long.
