Has anyone installed oil squirters into a b18b ls block? If so what all do you have to do to get them to fit. Ive found the oil galley where they go. Some people say there not required. But im still going to use ITR pistons and there cast so.

 

a good question i would like to know the answer to also......any one that has had it doen what machine work had to be done?? What kind of instructions or measurements would have to be given to a machine shop to get them to be plug and play in the block?

I have thought of this but never did it to my own LS

 

anyone?

 

I know it has been done i the past.There isn't any real power or reliability to be had so nobody really bothers with it any more.If you really want to pursue it give Endyne or Benson a call,I'll bet they both have done this in the past.

you realy dont need them if your engine is going to be N/A with stock honda parts. The only time you will need oil squirters is in high horse power or turbo applications, so that they can cool & lube the pistion bottom, but there nice to have anyway.

Actually, you'll need them if you use stock honda parts in a LS/VTEC or B20/VTEC, reving to 8000 or higher. The whole reason the oil squirters are there are to cool the weak cast stock pistons. If you use forged pistons, you shouldn't need them, at all.

 

So how would I go about installing them?

 

It is pretty difficult to do it right, honestly.
The only way I've seen anyone do it right is by making a 1/2 tall standoff, probably out of AL, one side being flat, the other is pipe threaded. Drill and tap the oil galley in the proper places and screw in the standoffs. Usually, they are epoxied in, so they are perm. Then, drill and tap for the squirter bolt, which is a very very uncommon thread size. You can't just drill and tap the block because of a few reasons. Number one is there isn't enough AL there for the threads to grip, you might get 3 good threads, which isn't nearly enough for such a fine thread. Secondly, the surface on the bottom of the block isn't flat, so there won't be a seal, and oil pressure will leak between the squirter and the block. If your squirter bolts blow the threads out, it could mean disaster for your engine.

 

look you really dont need them b/c stock type r pistons are a combo of cast & forged and a cheap alternative to oil squirters is to ceramic coat the piston skirts.

 

Actually, you want to ceramic coat the piston tops, not the skirts. The skirts are the sides of the pistons and need lubrication, so they should be coated with a coating that provides this.

 

You are right, Ceramic Coatings do go on the piston top. However, oil squirters are not necessary. Stock honda components will withstand revs of 8000 RPM for extended periods of time with proper maintanance. Type R pistons are designed to withstand the stock powerband to 8000 RPM +. I've worked on several cars with oil squirters. Turbo DSMs use them. They use them, however, b/c the combustion temperatures can cause excessive strain on the piston and the inner dome of the piston needs to be cooled to prevent failure (DSMs also have cast iron blocks as do CA18DETs). Honda pistons (most) are a combination of cast and forged. In a properly built motor with efficient cooling and oil delivery oil squirters are not neccessary. For the price you would pay to have the squirters installed and working properly and preventing leaks, you could spend the money and buy upgraded cooling components to lower the coolant and oil temperatures or perhaps a method of cooling the intake charge that will in turn lower combustion temperatures and we all no cool dense air equals power. Squirters may be "nice" to have, but they are not neccessary for that set up. I would be more worried about are the stock sleeves on a b20 failing and maybe searching out a crank girdle for the LS-VTec. You'll be fine with no squirters and no girdle, but if you want to go ahead and be safe throw a girdle on it before you waste money trying to machine in oil squirters.

 

Well, I disagree. If you are using Honda pistons, use Honda engineering and install oil sqiurters. Same being said for the crank girdle, if you are using higher revs and R/S ratio below 1.7, use the girdle, Honda did.

 

I think you will be fine by installing an exturnal oil cooler, it will cost you less or just get an gsr block and use your Ls rods and crank.

 

oil squirters are NOT "neccessary" on <U>ANY</U> engine, regardless of piston material, but they are an added bonus for a street car.

you might as well keep them if you've got them on a daily driver. On race engines, they are not needed, and actually rob horsepower (although its a very minor amount). Not sure if I'd go through the hassle of machining a non vtec block for squirters.

I've had no problems with non-squrter engines yet. I've got 8500 rpm ls/vtec's with cast pistons running over 50k miles with zero problems, and NO GIRDLE.

<U>don't believe the girdle HYPE. </U>

 

Like I said, Honda engineers installed them for a reason. If you understand economics and production, you'll know that a car company doesn't do something "just for the hell of it". If it isn't needed, it isn't installed/created/engineered.

The End.

He has a LS block.Honda chose not to install squirters in that block so thats proof that it doesn't need them.

if u want the same effect as the oil squirters just run some h-beam rods or somethin..that h-beam helps splash more oil up under the piston almost as good as oil squirters sprayin up under the pistons

Right, because they designed it to run max of what, 7200 RPM or something? Geez, I give up with you people. Think outside the box.
