i think what Ep was trying to get at, is those cars idle like shit, and idle at a lower RPM, what will happen at a 500 or under idle, the oil pump isn't pushing the amount of oil a motor needs to function properly at idle, and hence, killing bearings over time.

that and well, there's a handful of people you DON'T want to contest, you just take as gospel, and Ep is one of them.

 

500-750 rpms is a HUGE difference than less than 500 rpms, especially when it comes to oil pressure.
And yes, you do drain out little flakes of metal out of your oil every time you change it. What do you think is in your oil filter?
Take a perfectly healthy engine, and cut the oil filter in half. You will all but panic when you see the amount of crap in there the first time.

And to your point, I would be willing to bet that the shorter stroke of the dsm engine plays a major part in that. I had an Ex that drove an eclipse with no IACV. But, they don't need it to idle. On our cars, (KA engines) when the throttle plate is closed, its closed. The only thing keeping the engine idling is the IACV. The glued screw is the idle adjustment. when you take that off and seal up the hole, the engine will die as soon as the throttle body is shut. that's why you have to set your idle off of the throttle cable when you don't have a IACV on a KA.

Also, just to further the point a bit more, watch your RPM gauge closely when you start your engine. I bet it takes less than .5 seconds to get over 500rpms.
A stumbling engine can be below 500 rpms for 1-2 seconds.

thanks man, appreciate it.

And yeah, that's the point I was getting at.

sooner or later I'll figure out how to get my point across without needing a total dissertation.

lol

 

its an eaton m62 i believe. im going to run it by cutting the lower intake manifold right below the flange and making a simple box aluminum adapter with a flange for the s/c so i can use a gasket. i figure there will be a space on the backside of my adapter to simply tap and mount the iacv unit.

 

if it is off of a frontier or whatever, it is a m62.
what's the power goal?
boost level?

just curious.

 

ehh, im not sure of the boost level stock. its the blower off a thunderbird v6 s/c coupe. im going to run 470's or so with a rom tune. i should be able to make 180ish, maybe a bit more if i'm confident with my bottom end.

 

Well, you're right, I am definitely out of my element. lol.

I understand that excessive idling at low rpms can cause oil starvation. I thought we were just talking about the car bouncing off 500rpms and idling up after less than a second, which is my experience with DSMs and no idle control. We do have a bypass screw (independent from the throttle stop) which can be used to bring the idle up after deleting the idle speed control motor.

I didnt know about how the KA IACV works tho so thank you. lol

Also my stroke is longer than a KA24...I drive a 2.4L DSM

 

yeah, just that isn't that big of a deal. I've watched the needle all but hit 0 on those cars with no iacv. and since it is so long, it stumbles on itself to get back over 500 rpms. so it could take a couple of seconds.


no shit huh... you just stroked out or what?

 

that's not so bad.
should be able to get more, especially with the bigger injectors and all that jazz.

rhart is designing his set up, but he'll be intercooled.
I'm really curious to see how different the two end up power wise

 

Meth injection FTW! Thatll get ya over 180 with enough boost haha...470cc should be good for ~240whp..its all in the tune...gotta watch the knock..

Empire: I run a 9.5:1 comp 2.4L block from a 98 galant... 87.5mm bore x 100mm stroke.
