CA18 oil squirters thread size/pitch/length?

[240Clarke]

Can anyone inform me of the thread pitch and size of the CA oil squirters? Piecing together a delete kit and my motor is still at the machine shop. Also, how many mm length?
Thanks

[240Clarke]

Anyone?

I'm no help, sorry. It's not a common question.

[240Clarke]

I know its not. Just knew if anyone was to know, this would be the place to ask. Not having fabulous communication with the builder, waiting for them to give me the same information I asked for here, even though my short block should have been done by now. And they cant even assemble it until I give them the squirter deletes...

[float_6969]

and the builder can't measure the threads?

If your builder call himself or themselves a builder, you shouldn't have to ask this question as you are paying premium dollar for their expertise. The answer to your question is: M12X1.25 He can figure out if that's metric or standard (I hope). Good luck with that build.

Sorry man, I gotta ask what myth did you hear about when it comes to the CA18DET that's forcing you delete the oil squirters?

[float_6969]

I was wondering the same thing

[dhen]

CA18DE blocks are more common than DET blocks in the US and the DE blocks don't have oil squirters. Other than oil squirters, the two blocks are the same. If you've got a good DET block you could probably sell it for a profit and replace it with a DE one.

Just a thought.

i hate to jump in like this but i had to delete mine do to my wiseco pistons any thoughts on it

[float_6969]

That's why we don't recommend Wiseco pistons here unless you're a DE w/o squirters already. The long story short on squirters is that they reduce the chance of detonation by keeping the piston cooler than it would be without them. Especially on forced induction engines, they work.

[bimeur]

Or you have another solution i've made on many ca18det's with Wiseco pistons :



you delete the red pin, you turn the squirter enough to allow the piston not hitting it.

That's it.

Food for thought:

Thousands of people turbo their 2JZ-GE engines, which didn't come equipped with oil squirters like the 2JZ-GTE did, yet still enjoy great reliability and impressive power numbers.

I still want my squirters though.

Matter of fact, one of my squirters broke during install (make sure the little holes in the block that the little pins insert in (the thing circled in red in the pic of the last post) are clean of gunk/debris so they can actually slide in as you tighten the squirters down). I actually had it rewelded to fix the crack that formed on the soft aluminum from being tightened down crooked. No issues so far.

[240Clarke]

I don't have cast pistons. Turbo squirters are not necessary with forged pistons. I'm sure they extend the life of the motor slightly, but they aren't needed. With so many motors turbo without squirters, I doubt the CA has some design flaw that doesn't allow the motor to function without them.
And as for the builder, CNC Engine Dynamics, I just had poor communication with them and didn't know they had already taken care of it for me.

[zil40]

thanks i got the pistons a long time ago. I blocked the squirters on my last engine just was wondering what you goes thought about it

[float_6969]

I don't think anybody is saying you can't turbo a motor with out having squirters. Of course you can. Squirters help keep the piston cool, regardless of the piston type (cast or forged). A cooler pistons means a decreased chance of detonation, PERIOD. If you're motor isn't running near the knock limit of the fuel, then you probably wouldn't notice a difference. But if you are near the knock limit, and you're having to retard timing/add extra fuel to prevent detonation on an engine with out squirters, there is a good chance that the same setup WITH squirters won't require that timing retard/extra fuel, or at least not AS MUCH.

To simply say you don't need them with forged pistons isn't taking all variables into account.
