Overbore, and build the bottom end. Or... Buy another b16 bottom end.

 

buy and build a b18b bottom end.. should work out to be cheaper too

 

Keeping the same block for resale purposes.

Want to do this as cheaply and labor-free as possible (just removing the head, turbo, and piston kicked my *** today).

Don't think a hone will work those scuffs out huh?

 

A hone will get the scuffs out allright- but your piston will be slapping around in there and you will be burning oil. Either bore it or get it sleeved.

 

the cheapest most effective way to do it without sleeving it is, but a block gaurd bring it to a machine shop and have them weld it in and make sure they drill out the holes for the coolant!! have them bore it 20 over and there you go. i myself wont build a customer a motor for a turbo application without sleeves. i have seen too many stock sleeves crack and just dont trust them. but i know that works well and that is probably your best bet.

My goal is not to build this motor for heavier boost.. it's to simply get it back on the road.

If I wanted to build it, I sure as heck wouldn't use a blockguard... I'd go w/ Darton/JE/Crower.

 

look man im not sayin that is the way to go. but if you want to get it fixed right you would sleeve it. but since your not you should atleast use a damn blockgaurd. you asked i answered.

So what you're saying is...

Anytime a normal person with a normal car has a SLIGHT problem in a cylinder.. the whole motor should be removed, gutted, sleeved for over a grand, and have all new pistons, rods, bearings etc installed for another 2 grand.

I didn't think so.

Three of the cylinders made 220psi. Only one cylinder was low with the cracked ringland. This is not as of crazy of a fix as you think... it's not like the sleeves are cracked.

 

You cannot hone that block .... its half assing it to say the least. It may get you on the road again but you will be consuming a lot of oil which will lead to other problems down the road.

 

Well, my #4 piston looked about twice as bad as that and I honed it out and I did a compression check today and it was 235psi.

I've honed dozens of cylinders much worse than that and never had a problem. I wish I still had the pictures of my cylinder before and after.

Try it if you cant afford $1000+ on sleeving.

 

Just expect to rip it apart and do what you should have done in the first place sometime along the road; You won't be happy constantly refilling your crankcase w/ oil.

 

Again I totally agree with this. Do it right the first time or be prepared to do it over again!

 

If you brought that engine into a Honda dealership, they wouldn't even hone it, they'd replace the piston/rings and put it back together.

"Light Verticle Scoring is Acceptable. If it catches the nail of your finger, a hone maybe neccesary. 20 Cycles @ 50 RPM with a rigid stone hone should be suffecient to smooth cylinder surfaces. Advise customer to replace oil in 1000 miles after they have taken the vehicle."

Really, if he's not going to being boosting this engine and is actually selling it very soon and he cant afford to resleeve it then he's going to have to fix it the best he can. And I dont see anything wrong with it.
