this next semester i will be building up an sr20 for a turbo in my engine building class and have seen some peolple on here say they have added squirters to their na blocks. i have done a search but can't find a post that says where i can get these, i've also tried on the rest of the web with no luck. any suggestions?

^^^^youre wrong^^^^
the area you speak of is simply a hole for the rod bearing to gain lubrication

oil squirters bolt into the block right under the pistons and squirt oil onto the pistons underside

theyre pretty hard to get a hold of.... if you look on George Roffe's website he has pic of them that shows the part# then you can probly order them thru courtesy.. I also heard that the KA24DE engines use them and they are the same... not 100% on that but itd be worth lookin into finding a junked KA24DE for parts, unless you can find someone parting out a DET block...

I was lucky enough to get mine on here, ive seen them go on eBay for $55 and i know Andreas used to have some 4 sale......not for $55 though..LOL anyway best of luck to you...

You are right not for $55

I sell mine for $15 each one which comes to a total of $60 for 4 plus $5 for shipping which is $65 total.

With me altleat you know you will get your part.

I think its a waste of time. I saw no change in egt from stock to the squirters. This was done on my na motor. for the machining process to the tapping and the install. spend the money on better parts.

You are not serious with that quote are you. Oil squirters will not cause the EGT to drop. Oil squirters are for cooling the pistons for high compression and high boost. Oil squirters spray oil on the bottom of the piston which cools or removes the heat from the piston, thus allowing your piston to take a higher abuse level.

yup not supposed to change EGT... just a little extra insurance if you decide to run stock cast pistons or to keep your forged units a lil cooler on the underside....

the DETs are well made engines they mustta had em on there for a reason.......

P.S. $65 shipped is a good deal and Andreas IS reliable!!!

Hey supercowboy,
I'm curious about the motor in your nx. Can you detail how you squeezed 185whp out of that thing? What kind of cams are you running? What's the compression?, etc. Maybe you could put it in a new thread?

The theory is there but I didnt see any change. This will not make any power.

What is the differance from a hot and cold piston? How can this aid in more abuse? If the piston was getting that hot wouldnt that cause the small end of the rod to fail. This is only a bronze bushing.

DET also have bigger oil pumps to support the turbo and the squirters. The de pumps really cant support that type of volume. you must shim the pump bypass to .040 just to get some more oil pressure. This causes the pump to flow less volume.

andreas??!!

(andreas) i have done a TON of searching on all the nissan forums and your name always comes up and you always have good knowledge/advice to give. i have many more questions about my rebuild and things i want to buy, whats the best way to communicate with you(PM or email?)

Oil squirters are not desighned to make more HP they are there for cooling the piston. Which will allow you to run higher boost levels, higher compression levels and leaner mixtures.

What is the differance from a hot and cold piston? How can this aid in more abuse? If the piston was getting that hot wouldnt that cause the small end of the rod to fail. This is only a bronze bushing.

Its easier to burn a hole in the piston with out oil squiters. The oil squiters remove the heat from the the bottom of piston and also leasens the chance of detonaiton. Think of the oil squirter as a water sprayer for an intercooler. It aids in removing the heat.

The hotter the piston the more likely it is to melt or take out the piston crown

The small end of the rod is not in the combustion chamber so it is not exposed to the hostile temps that the top of the piston is. The broze bushing is also highly lubricated with oil.

How is that possible?

I beleive the squirter aids in getting the piston pin more oil. Why would you direct a small amount of oil to one part of the piston. wouldnt this cause the piston to be cool on one side and not the other. dont forget there is alot of windage under the piston.

This is caused by detonation

The faster it moves the more friction they can make the more heat it will create. A 200hp motor spins up faster than a 140 hp motor.

Supercowboy, I have answered the question twice. If you think I am wrong just pick up an auto book on how motors work and have the book answer your questions.

If you belive I am wrong then I am wrong. SO I can not help you or either I am not versed well enough to answer your question.

Andreas I never said you were wrong.......I just have a hard time believing The oil squirters cool the piston like you say it does.

i realize adding squirters won't add horsepower. my intension as andreas pointed out, is to keep the pistons cooler. as we all know hot spots on a piston can cause detonation which i am trying to avoid since i will be boosting a detonation prone 10:1. can't really see anything bad with doing it, other than the low oil pressure. i can say with confidence that a piston will be hotter than the oil hitting the bottom of it. how could it not cool it some?

well i looked at other options and i thought of getting the pistons swain coated. anybody think this would be a comparible help? thanks
