1G Buy a Short Block -or- have machine shop work on mine?

[91Bomb]

I spun a rod bearing and trying to decide whether to disassemble my stock 7-bolt motor and bring bare block, crankshaft etc to local machine shop and let them do their thing and also have them assemble it -OR-buy a short block and get it shipped. Although removing/tearing down the shortblock is not a problem for me, I don't know of any machine shops locally that work on 4g63's so i'm worried about winding up with quality work. I also don't know where to buy a known good shortblock but do see them on ebay for $1500 shipped for a stock one. (I'd have to send my core so that's probably more for shipping and my crankshaft is bad so I'd be charged extra for that)

So, how much am I looking at to have a shop work over my bare block, crank, etc and then assemble it for me -or- does anyone know of good stock shortblocks for reasonable price? Which of these options make more sense? This is for stock application and I'm running free/cheap mods at 15 lbs boost and would always be below 20 lbs for sure. Thx!

I stopped letting machine shops touch my engine blocks and cylinder heads after several shops couldn't get it right. The dip chewing toothless rednecks are used to v8 tolerances and don't calibrate their machines.... it's very difficult to find a machine shop to trust with your expensive toys. Most of them will blame you for the failure that their "workmanship" caused as well.

I'm not saying this only from my personal experience, I'm saying this from the experience of not only myself but others that built more motors than I did. I'd get a shortblock from a reputable vendor or find another shortblock that is used and was last touched by the mitsubishi engineers. N/A bottom ends are just fine btw. I had a 1.6L (4g61) n/a block in my talon for a long time that I put a 2g head on with a s16g turbo @23psi daily driven. This was the ragged edge for that turbo and the N/A pistons never had an issue. I'm not suggesting that everyone is going to agree with this, but it has worked well for me. When I break something in an engine I replace it with another used engine rather than messing with machine shops that will take my money to fubar my equipment.

I do have a shop here that a few local dsm'ers recommend.

But yeah I'm real nervous especially since I'd be having them put the rotating assembly together. Best I can do there is give them the specs and hopefully they'll get it right. Doubt I'd be able to check all engine tolerances and then assemble myself from watching youtube vids.

Whatever shop you chose, make them SHOW YOU the clearances before you pay for or pick up any thing. Once it leaves there shop, they are pretty much off the hook. Make it very CLEAR from the begining you want to SEE IN PERSON, the measurements, with the correct tools (dial bore gauge, mic, etc) before you pay for or pick up anything. If they aren't willing to take the 10 minutes to show you they did the job correctly, they aren't worth a dime of your money. JAM is a supporting vender on here (with a good rep) as well as Boostin', and others.

For the current prices of built blocks offered by venders currently. Makes me lean towards buying one built by JAM or Boostin P. before i would allow a shop to build mine. The down time you save with a rotating assembly arriving fits into my schedule more then building one from bottom up. But on the other hand there is something about doing it yourself and doing it right.

I would look for a recommend machine shop that has worked on DSM EVO engine in the past.

Checked out their site after reading your post. Have you purchased a motor from them? What specs and what power are you currently at along with price points.
