oil squirters vs. ceramic coated piston tops or both

[crazytsiawd]

Looking at getting a bit more info on what route to go, would there be much benefit if i decided to run ceramic piston tops with oil squirters, kind of leaning towards just the ceramaic piston tops.. car wont be running any autox events, and will be used out at the drag strip and some fun on the streets.

Easy answer, whatever you want to do.
Some people will say you don't need the squirters so don't use them and others say that cooling off your pistons is always a good idea - I fall into the later group.

If you block them off you will have to deal with high oil pressure so I would just use them. Check out EVO squirters, that is what I put in my car.

Also the six bolt had squirters and very few crank walk issues. Seven bolt they were eliminated and had more crank walk issues. The new EVO's have squirters, that tells me that they should not have been eliminated.

Always run squrters.

7 bolt had oil squirters also. they're "Integrated" into the block and don't bolt on.

But OP should run squirters, even though you can get away without using them, why wouldn't you want to cool the pistons? its a no brainer for me.

I don't run them. Found the piston scrubbing on the opposite side of the squirt. I find that running them in a car with under 500 WHP is not an issue.

Run them. If you have a clearance issue between them and the piston, simply adjust the squirter nozzle.

Or just do both.

Its only the 2nd gen squirters that where an issue. 1g squirters are narrow and always squirt. 2nd gen had bullet style squirters with a spring and check ball. They are only supposed to open and higher oil pressure and feed the crank while under idle and low engine speeds. Then when your oil pressure rises during accleration the check ball would open and allow oil to squirt. Problem they found was that the 2g squirters would get sludged up. Even in a pretty clean engine. They would get stuck open and rob the crank of oil pressure during cold start ups and during light cruising. Your engine slowly starts to eat the bearings, mainly the thrust bearing. Magnus motorsports has a write up on this. They wanted to know why the 6 bolts are not walkers while the 7 bolts are. They cut up 6 blocks on a jig saw. Most oil passages are all similer between the 6 and 7 bolt engines. What they did find was that almost all of the 2nd gen squirters where indeed stuck in the open position even when high pressure air was blown through it in the way that it should close them. They weld the holes shut on the 7 bolt engines and run grooved pistons that are ceramic coated instead.

I always have ran squirters and never experienced any oil pressure problems. Even other manufactuers like GM and other have moved to putting squirters in their factory engines. The Generation V SBCs are all going to have squirters N/A and boosted.

here's a thread on my squirters, 2.3 using evo squirters had to bend them to fit
