My 2.0 is beat.

I have a chance to get a 1.8 for under $100

What if anything is different. I assume I need a 1.8 ecu. Anything else different?

Injectors, sensors?

 

injectors, ecu, pistons, and im not to sure if the crank and rods are diferent. but thats about it.

i dont even think you need a 1.8 ecu yours should work.
should be a direct swap no problems

 

I think this would be the first reverse swap lol

what happened to your 2.0L

 

2.0 shat on me.

I removed the turbo kit and sold it. I ran it with low oil pressure and I believe my piston is now hitting my spark plug.

I am going back to stock. Will the 1.8 be ok with my 2.0 auto trans?

 

low oil pressure would not let the piston hit the plug... even if you ran without a timing belt.. the piston should NOT hit the plug.. valves yes, plug no.

I think you need to figure out EXACTLY what happened to your 2.0. Hyundai engines are pretty robust in a NA application and can take a lot of maintance abuse.. (except for the HLAs) I would have the car's compression tested, perhaps even pop the head off, before I would go through all the trouble of downgrading your car.

 

You are right. I should try to fix it but, if I can get a 1.8 for $75, I might just do that.


I abused this engine. The first 70k was pizza delivery miles and a lot of WOT torture. Then a lot of WOT turboing. Then removed turbo and drove it with the oil tap from the head leaking pressure and a hole in my oil pan. There were a lot of grit and metal shavings in the oil before this happened.

I just want an engine that was stock it's whole life. It is probalby easier/faster/cheaperfor me to put a new engine in than tearing the old one apart, then fixing it, then hoping it lasts.

The entire plug from cylinder 1 was smashed and the had no gap and the electrode was bent to the side. The engine makes a VERY loud knocking.

I will try to get a video of it.

 

I would say that you have something loose inside the cylinder.. or did.. probably crushed into the soft metal of the head by now

 

That is what it seems/sounds like.

I am buying a 1.8. Does anyone know if there are any issues with the 2.0 Auto trans on a 1.8?

Guess I'll be the first to find out.

 

Engine is out.

Had to find a 41 mm Flex plate. The 35 would not fit.

1.8 is going in Friday.

 

I'd try to grab the 1.8 ecu as well.
