Cyl boring -quick question

Can cylinders be bored out without taking the engine out of the car?
I have a couple of cylinders that are low on compression and the pistons will probably need replacing, I was just wondering how expensive this would be.

I would be getting all 6 cyls bored out and new pistons for them. What pistons would be good replacements? (would probably pay a bit more for good quality ones.

If you could, it would be harder than just pulling the engine out.

I would stick to standard ACL pistons, they are strong and well priced. I asked about getting stronger pistons but they were all going to cost around $1500 for a set.

If you are going to spend the money for new pistons, take the engine out & get the block machined professionally.

Check for valve leakage.

Re: Cyl boring -quick question

You should be able to get an ACL Race Series rebuild kit for a touch under $1000. They have better pistons/rings/bearings etc, but aren't over priced. I am building and engine to handle about 250rwkW using ACL gear, it's really good stuff. It is a pain pulling the motor out, but you are better off doing it the right way once than having to pull it down again 6 months down the track. My engine has cost me about $2000 to build with A LOT of work done to it, most was done at mates rates, but it shouldn't cost you a hell of a lot more.

Re: Cyl boring -quick question

I got my kit for $710, but that was WELL under trade price. Retail was above $900. You don't get guides or anything. All you get is pistons, rings, bearings, gaskets and welsh plugs. Cost me $140 for new valves, $89 for a high volume oil pump and $65 for a timing kit.

You might be able to get away with just rings and bearings, depending on how worn your bores are.
