What is that turbine housing wrapped with? Looks nice!

 

We have never added a set to a motor and never had an issue as a result of not having them.. Personally i like not having them.. the oil pressure remains much higher on the 2.4L without them..

Mike - If you have never added the squirters to a 2.4L block then how can you say the oil pressure is higher without them ? And where is the oil pressure higher - block, head, where ? And what pressure is too high and what too low ?

I'm not being a smart a$$, I am just trying to understand...

I doubt anyone would have an issue without running oil squirters on a 2.4L, but to me it seems like it would be better to do it.

 

I have ran many motors starting from 2004 with no oil squirters and have not seen anything that would make me want to run them.

What I have seen is most of the forged pistons end up hitting them and you have to bend them to clear and if its a high rpm race motor most of the time they will break off and fall in the pan. Lucky the way they break does not seem to cause any problem.

Not sure if its a no BS shaft race motor thing or the fact that you have to mod them to clear is why they break.

 

I gave you bunch of reasons why not to run oil squirters, very important reasons why not to, and so have two of the most reputable guys in the evo community and you still say it would be better to do it?

reading comprehension is your best buddy. they are not required nor needed in a 2.4 as mikey stated 2 great shops have already chimed in and stated dont bother with them. My knowledge comes from reading and calling shops for more clarification. I built a 2.4 twice and no issues. Chances are likely if there was any type of issue without them AWD ENGLISH RACING AND SLOWBOY WOULD HAVE found out awhile ago and informed us all

 

geeze, you guys live in such a black and white world. "if it doesnt break, it must be fine!" there are pro's and cons of oil squirters. are they "needed"? no. are they going to cause problems? no. are the pistons and rings going to last longer with them or without? probably longer with them. on your average street car they are obviously not "needed" but if i was building a road racing car, you bet your *** i would run them.

 

Okay since you wanted to bring up the pistons/rings... In build motors what part usually goes out first? It is the bearings not the pistons/rings. Why would you take away oil from a part that is statistically known for failing first?

Mikey

 

sometimes its bearings, sometimes its ring/piston wear, sometimes crap just happens and something random breaks. im all for eliminating as many wear/failure points as i can.

 

like i said, they have their purpose. ams uses them in the 2.3rr but not the 2.1 drag motor. it all depends on the intended purpose of the motor. im most likely not going to run them either.

 

what about the 4g63 built motor do you need them in that or would it be better to cap them off like honda guys do so that they have more oil to parts like bearings and such?

 

imo, i would just do the balance shaft delete, buy a kiggly hla, and keep the squirters. the first 2 raise oil pressure a bit and squirters are beneficial, especially if they are already installed.

 

Guys - We are all trying to make these motors as best as possible. Let's try to help each other out however possible.

Mikey - Thanks for your reasons for not using squirters. As I acknowledged your reasons are why drag racers don't use them. For those of us that road race (or did) the more common practice is to use the oil squirters. (Thus my bias.)

Aaron - I totally agree that an engine builder would have to ensure that the the piston does not hit the squirter. I also believe that most would be fine running without the squirters. I just feel for a road race car or one that is pushed really hard for long runs, the squirters would be added benefit.

Rockman - I was just saying that I never said squirters are required and then you posted saying I did...It's all good.

 

I honestly still wouldn't use oil squirters if I road raced... A lot of road racers lose motors with bearing failures due to oil starvation! I would be willing to bet most of the failed built blocks had oil squirters. I can't fathom the fact of taking oil and throwing it on a piston that is forged. Just my .2 and you guys are obviously going to do what you want. Even a lot of people think that the oil squirters in the 2g is what causes crank walk... Marco which has one of the fastest 4G63 in the world say they can cause crank walk. Every high hp built motor I know of doesn't have oil squirters, R34, 2JZ, every built Honda etc... It is just not needed on Forged internals.

Mikey

 

Well the ZR1 and the 911s have them (as do most of the crazy exotics that most have never heard of), but I am guessing that is because they run dry sump systems. The aforementioned all have forged internals too. Maybe that is the issue, most of my experience has been with cars with dry sump setups.
