I've heard around that the oilers in the GSR blocks are just for cooling the stock rods and pistons. But after forged go in, they're not needed anything as the crank and rods oil the cylinder walls. I'm building a boosted car and was wondering what the advantages and disadvantages to taking these out vs leaving them in would be. let me know.

ReDHaTcHyGuy

the reason they say u don't need them is cause the forged piston cool easier than stock , and blocking them off will bump up your oil pressure, when my buddie built his motor he chose to leave them in , he actually went to honda and bought new ones..he figured honda put them there for a reason plus it wouldn't hurt to have the extra cooling even on forged pistons... go to golden eagle's website they sell the kits to block them off , there is probably info there that may help

built blocks dont need them, they are just needed to cool the stock pistons. take them out.

pros - more oil pressure

bump for more good info!

But wouldn't your pistons running cooler be good for them as well?

no, the forged dont have problems

So what would be the correct way of cutting them off? Just tappin the holes and put a screw in or do you have to shut off both sides?

come on... I know more people know about taking these out!!!

Your not going to cut anything. Just tap and plug

Cutting off meaning block the passage way

ive always reused the oil squirters.

think about this. s2000 has forged internals from the factory, they still have oil squirters. honda did this for a reason.

i always thought that you dont want too high of an oil pressure for turbo anyways, whats a CON to keeping the oilers? ive always decided to keep them on

that says it all right there. i am going to reuse mine

I kept my oil squirters, I dont care what anyone says, Forged pistons benefit from it too.

Any ideas why a high reving Honda block such as the F20B (destroked h22), does not use oil squirters while the h22a1 and a4 do?

I always block them off in my forged builds. I cut the nozzle off and then spot weld the base shut.

aluminum is one of those metals that gets significantly weaker with increased temp. Also, forged pistons typically have a higher coefficient of thermal expansion, keeping them cooler could mean you could run tighter clearances..although no one actually does.
There is a reason honda built the vtec engines with the oil squirter/oil cooler combo, eliminating it is definitely bad, especially with forced induction.

I don't know why but I always hate these "I'm going to take my oil squirters out" posts.

For street and endurance engines you should leave the arrangement as is. They will do nothing but help your motor regardless of what you have for internals. For highly tuned drag race engines you can find a few horsepower by plugging these orifices. This reduces the oil that falls on the crank, which then robs it of horsepower.

If the oem piston expands .001, it is curtains for the block.
Having said all that, you can run the squirters or not. There is no wrong answer to the question.

Im with this guy, but i dont think you should plug them on a street car
