I agree that solid lifters will be better for performance but not practicality. With solid lifters, your supposed to check and reset the lash like every few hundred miles or something like that. If your not building a track only car, stay away from solid lifters.

 

I think having the oil-squirters is a really good idea. It lubricates the wrist pin and the cylinder walls, and helps to cool off the piston. On a turbo car these all matter. The 4G64 is not turbo from the factory, no squiters. The 4G63 is turbo, has squiters.
The squiters can increase the life of the motor, and could help prevent detonation to some extent. The only real downfall is increased cost...

Vote YES to oil squiters!

 

As promised, I am going to have a few weights for you today!

Pistons are on the scale now, and will be listed here in a bit. As I get more pistons on the shelf, we will be sure to yank them out of the box and weigh them!

All rods are EVO spec rods.

MGP - high performance, aluminum rod, proven in 1200 plus HP in 4G63T.
Manley 14022-4 - H beam
Eagle CRS5900MB3D - H beam
Stock Evo
Manley 14403-4 - I beam, stock length
Pauter - MIT-220-480-1500F
Manley 14499SB2 - I beam, long rod 162 mm

The solid lifters are only to be used to degree the cams. I would never advise anyone to run them full time, even on a drag car unless they are a glutten for punishment.

 

Let it die, plus you don't have a clue as to what your talking about.

Lubricating the cylinder walls....

 

Great info and thanks Mike.

I'm suprised the long rod didn't weigh more than it did vs the stock length rod.

Can't wait to see the results on the pistons.

 

Go home newbie...

you neglect to realize that your making statements with broad generalizations. "4G64 isnt turbo so it doesnt need squirters, 4G63 is turbo so it needs them" Have you ever thought that maybe some people turbo the 2.4 block in SOHC form and make a good amount of horsepower without squirters and dont have trouble? They also make supercharger kit for the 2.4 SOHC that puts just as much punishment on the internals, they dont run squirters and they hold up fine. Other manugacturers dont run squirters, they are OK. You say the squirters "can" increase engine life and they "could" help prevent detonation. lets see some proof, lets see stats, lets see comparisons, without that stuff, your just beating around the bush. Im not trying to flame you, im just saying that when you make a statement, include some type of real world example or some facts to support what your saying. Weigh out the cost vs the gain. Lets say for example, if someone proved that squirters would make an engine last lets say 10,000 miles longer then without, then you can compare and say "well, hmmm... how long do I plan on running this motor, how long do I plan on keeping this car? how many races do I expect to get out of this motor before I send a rod thru the side of the block?" then you can actually make a good comparison of the investment vs. the return

 

you know all this scientific crap is cool but how about some real world facts...

I have ever heard of ANYONE ever having preiginition problems on a 4g63/4g64 because squiters were missing. My own car was a dyno for for 3 hours any never had preignition. I daily drive my car and beat the **** out of in traffic and have no problems.

If a piston is expanding enough to seize or ruin a cylinder a wall an oil squirter is not going to prevent that.

 

he was actually providing good info.

No one stated squirters will prevent total failure. What they do is prevent premature wear and promote long engine life with good cylinder pressure (especially if the engine is driven at high RPM's for extended periods of time). I agree that in most applications, they aren't needed. But it is very wrong to assume that they do absolutely nothing. Considering that most rebuilt modified engines are only going to last 10,000-30,000 miles before they are blown up again, maybe it would be better if they are not installed.

 

Exactly. I dont feel they are needed either and SBR is in agreement with this as well. Considering the fact that they built my motor and I asked them directly if the squirters should be installed.

Not alot of people in the Evo community run this motor...yet. Time will tell.

 

My man, your sounding like a bad engine oil commercial.

Premature wear of what? As I stated before, the only thing that should EVER wear are the rings. Nothing else should ever touch or rub the cylinder walls except the rings. If your pistons are touching the cylinder walls then you have a bigger issue than whether or not you have oil squirters and if you do have them their not going to stop the failure that is going to happen.

Also, please explain to me how good cylinder pressure relates to oil squirters.

The only thing that the oil squirters will ever do at their best is control heat at the bottom of the piston....that's it. So that means instead of burning a hole through the piston from detonation it instead holds on for a few moments longer.

If your that concerned with heat on the piston tops, call Swaintech and give them your pistons and your credit card number.

Can we rest this squirter thing now and get back to the original discussion?
