Did you do a leakdown test? From this picture it looks like your downpipe is covered in oil...was your manifold coated in oil (rings)?
Attachment 209862 Take better pictures for better analysis. |
I thought having a sensor that close to the exhaust source would kill it in short order too? Shouldn't it be as close to the beginning of the cat as possible?

No leakdown test ,because here in Greece stupid engineers dont know shit about this.
Downpipe has a huge amount of oil in it. |

what's that in the coolant galley? Is the vertical scoring as apparent in real life as it is in this picture? |
I've been in your shoes. Now is the rebuilding stage. Decide how much power you want because you'll only want to do this once. If your looking at pushing 350 rwhp or have a good budget, go with forged internals. If your looking for modest power, you can do a rebuild on the cheap.
|
That engine is done. Either go get another one from the junkyard or spend a lot on machine work. Whichever is cheaper and easier. If money is plentiful, build it up stronger. That galling on the cylinder wall means that little pieces of piston and maybe rings went through your turbo's exhaust turbine also. Inspect for possible damage. Any pieces may be trapped in front of your cat. Expensive lesson to teach you some restraint. Unfortunate. If you don't have a knock sensor, that may be a helpful investment also...
Some of the valve reliefs on your pistons are very shiny compared to others. Are you seeing evidence of contact there? |

So guys, i have 2 choices if the engine block can be fixed with overbore pistons.
1. Rebuild with forged internals. (I m wondering if m.tuned rods are ok.)I m thinking of m-tuned rods with wiseco overbore pistons (how much overbore ?) (off topic) 2.Used motor with thicker head gasket for lower compression. |
m-tuned rods are fine.
you don't want a thicker headgasket or lower compression. Paul's making over 300hp on a stock '99 1.8. |
1. Fine if you want to spend the $.
2. Don't need thicker head gasket. Lots of people run with the stock head gasket. Just a bit less boost, proper fuel, timing and you will be fine. It's strictly an economic decision for you. |
Hello again! I ordered wiseco pistons with 0.50mm overbore and eagle h-beam rods. How much hp will my engine be able to handle with this setup?
The machinery shop asks 550$ for overboring and fitting the parts. Also I m selling the gt2560 for a gt2876. That failure wasnt so bad at last... |
go with the 2871 over the 2876
|
blew the welds on the intake? jk. Same weird shit happend with my integra that was jrsc, never took it apart, swapped it and it was fine
|
Have you considered bigger injectors as well?
|
I have a forged motor, 550 injectors, gt2860rs, and I'm afraid to put it past 10psi without getting it to a dyno. lol
That price for machine work is awesome...just make sure you pick a good one. |

No need for upgrading the injectors as I m going to work it out with an 8 injectors setup. So 305s+245s= 550s . Brain why do you suggest the 2871 over the 2876 ?
I found one 2876 for cheap. |
Single injectors would be much more efficient, easier to manage (not to mention install), and support the factory flow characteristics.
The stock injectors are placed where they are for a reason (like placing fuel into the airflow right before the intake valves, and at the proper angle. Messing with this probably won't turn out ideal, unless you're doing flow analysis on your custom manifold (some have actually done this). |

Beside this I m running an emanage with the injector restrictions we all know. |
