bore and rebuild or replace block

[Asenseofpurpose94]

Well I have a 99 gsx which quit on me a few months ago and I just got the time to tear it down and pull the engine. So I found out yesterday I spun the rod bearing in the third cylinder and destroyed the cylinder wall pretty badly. After inspecting the piston (all pistons being completely burnt and blackened at the top) I noticed a small ding in the top where it must've hit the valve ..so only options that I can think of now are either look for a new engine or bore mine out and go forged. Only problem is this is my first time rebuilding an engine (that's not a little 1 or 2 cylinder) so I'm not super confident. What would be my best option and would going forged be worth it BC I don't have the money right now for a bigger turbo and fuel system?

any pics of cylinder wall so we can see if it can be bored or needs replaced?

yes some pics will help.

Sounds like you have more than one failure to figure out.

1) spun rod bearing #3
2) cylinder wall scoring
3) burnt pistons

I would figure out if your block is still good and do forged internals if your power goal are over 400. If you plan to build it yourself do a lot of research first.

If it were me, I'd take the bare block down to get inspected before I made a final decision on either route, and get a local shops opinion.

A reputable shop will be able to tell you whether or not it can be fixed with or without breaking the piggy bank.

For example, I had a motor bored, all went well... spun a bearing down the road, took it back in and they broke the news they had to sleeve it to fix it this time. Still not a big deal but it was more expensive the second time around.
