2.4 G4CS. Is oil squirters needed?

Hello guys, I haven't been here in some time. I have a 2.4 g4cs that I pulled from a '90 Sonata. My goal is around 500-600hp. The machine shop that I'm working with says its really difficult to put the squirters in this block. He'd rather I had a Mitsu. 4g64 block instead which he says has the provisions for the squirters. Can my g4cs block handle this kind of power without oil squirters?

 

Thanx

With forged pistons it shouldn't be a problem. The G4CS has provisions for the squirters, they just have to be machined in. That will be the same with every original non-turbo block, even 2.4 mitsu blocks. Only turbo motors got the squirters.

Yeah, I know they would have to be machined in. It's just the engine builder I'm using swares by the mitsu 4g64. He says in his expirence the 4g64 is easier to install oil squirters in than the hyundia g4cs block. He also states the mitsu block/crank is stronger. But he says he'll build on my g4cs block if I decide, it just may not hold up like the mitsu block with my hp goal.

They are the same castings so I don't see where there would be a difference but then again I do not build engines for a living. I believe your hyundai block will be fine even for your HP goal (dsm'ers have done it quite often). Hyundai and Mitsu cranks are cast. Find a crank from a truck 2.4, they are forged (I know for a fact, got one). With your HP goals you'll need forged pistons anyway so I wouldn't sweat the squirters no matter what block you choose to go with. I left them out on my motor.

May I ask what vehicle this is going in?

Kane thats what I thought, that the 4g64 and g4cs were essentially the same blocks built by mitsubishi. But, this engine builder believes these two block are not and that the 4g64 block/crank is better than the g4cs block/crank. I'd would think maybe he's lost and have no idea what he's talking about. But, he's been building DSM motors for some time with good success. And he was highly recommended to me over some of the higher profile DSM shops in the midwest. Also, you mentioned that the cranks in the cars are cast and the truck cranks are forged. When I looked in Topline's catalog all 6 bolt 4g64, g64b, and g4cs cranks had the same part #'s for both cars and trucks. This builder say that the g4cs has no provisions for the squirters and he definately wants squirters in a high hp block. He said the squirters are what saved one of his customers engine when all the coolant was lost and the motor overheated.

Topline is an aftermarket rebuilder. They don't care what it came from so long as it fits. When I worked for Advance Auto we had a Scat crank come in as a rebuilt unit from A-1 Cardone. Apparently a built motor found it's way into a junkyard and then got sold as a core.

 

A properly built car shouldn't lose it's coolant and the operator should notice climbing temps. :wink:

 

If your engine builder suggests it, go ahead and do it. It is not going to hurt anything by having them in there. I'm sure the DSM guys will take the Hyundai motor off your hands pretty quickly.

 

Still haven't told me what vehicle this is going in :?:

The oil squirters R ther to cool the crown of the piston only is stock form, originaly Mits engines were built to run for long durations at boost in stock form & to make the pistons last the oil was sprayed underneath to cool/remove heat from the there. Remember it was for long duration boost levels & CAST pistons. There doesn't seem to be any evedience to support squirter if yr doing short duration boost levels with FORGED pistons.

My 2.4L I had them machined in as it will be on boost for long durations, circuit racing etc, It also has the added advantage of supplying oil for the wrist pin in my eagle floating pin rods, giving them plenty of lubrication.
