I have a 00 civic si that I recently just turbo charged. stock internals and it was tuned with hondata and i was only pushing 5-7 pounds. sum how 1 of my vacuum lines ripped and was leaking so it ended up boosting a lot more! and i guess i blew my rings because wen its started it smokes from valve cover breather and exhaust, tho it drives almost normal. compression test was done and it reads 180-80-80-180. i believe my rings are gone but i wanted to rebuild it. would my set up be good if i replaced it with arias forged pistons and rings along with eagle h beam rods? i dnt think im going to sleeve right now since i cant afford it but im wondering if i used that set up wuld it be good? of course id get it tuned again. wat more do i need to have a safe running engine which wnt cause another mishap. please get bak asap. thanks

 

does hondata not have boost cut?

 

im not sure. does it? i had got it tuned tech3 a shop in san jose. apprently it didnt cut off since it has the engine smoking now. any help?

 

Something similar happened to my B-16, but it wasn't my fault. I was stranded out in the middle of New Mexico. Well I had a friend drive my car out to pick me up. He can't find a gas station that has 91oc so he buys REGULAR UNLEADED gas. Now what killed the motor was him boosting it to 9psi on that regular octane gas. He finally got to us and it was smoking and blowing oil out of the breather I had on the valve cover. Cracked all 4 pistons and had to replace my pistons. It still ran but it sounded like a WRX.

 

wondering if it could be a headgasket since the two middle cylinders have low compression. A leakdown test appears to be in order

 

not to be off topic but i love the way the wrx sounds. but back to the op. i agree with the post above.. cracked pistons

 

With the two middle cylinders being equally low, I would place money on it being a blown HG between them. That's a good thing, 70 for a new OEM hg and 120 for some new Headstuds (if you don't have them already) and 5 hours later you are back on the road good as new.

 

blow by rings are gone, do a compression test

 

Jesus H Christ shadetree!!! Read the freakin thread before you spout off incorrect info anyway. Compression test was done, the fact that the middle two read the same pushes toward headgasket popped between cylinders.

Go ruin another thread on another board with useless information that isn't correct please. Some of us are actually trying to help the guy out and not up our post counts.

 

oh man thanks for all the information! im going to open up my motor tomorrow and see whats the real deal problem... if it is the pistons and i replace the pistons and rods. wuld it run goood? can i boost a little more? wuld it all be safe? wat else shuld i replace while im at it? leave the head alone? thanks guys

To late already has

 

oil trick redo the compression test,

if comp stays low between those 2 cyls its hg, if not and oil trick raises the 2 and 3 cylinders, might as well replace all of the rings, i have rings with a lifteime warranty, beck and arnley from kragen
