Wondering what may be better for circuit use. Moroso aluminum pan or having the stock pan baffled for better oil control. I'm fairly nieve on this, so any comments are welcome.
btw: this is for a b20z block.
TIA

The kicked out Moroso pans have gates and are baffled. They also have the added advantage of one additional quart of oil, the cooling and weight saving of Aluminium. No contest in my mind but they may not be legal in many competition classes. Morso now has a dry sump pan if your serious I would consider it or if your made of money Spoon has a cast lower end reinforcing Aluminium pan.

Hi.

I have a Civic with a B18B1 motor (stock stock!) in it. I have at least 5k plus track miles on the engine (that includes 11 NASA/EMRA races), and never any oil control probs. First thing I did was install a pressure gauge, and I check it often when running. Never drops below 62-68 psi when above 3k rpm and hot.....

Now my Lotus, on the other hand, starves for oil even with the special race pan. I had to install a 3 qt accusump system to fix that prob....

So, I'd say for an LS B series (don't have any experience with any other Honda motor) that you should just use the stock pan....

I was under the impression that the Moroso pans, other than the 1.5 pan, were designed for drag cars. I don't think the baffles would help for roadracing. I seem to remember someone posting here saying that it didn't help them. Can't remember who though.

 

Get the Mugen baffle pan. It looks like stock, but has baffles to prevent oil starvation on road courses.

Hey Todd Reid,

All I have to say about guage protection is by the time you read it, low pressure, damage has already occured and all you can do is minimizing it.
This is not the clearest picture of the Moroso pan but it will give you an idea of location and direction of the gates and baffles. The arrows indicate the direction pick up oil is prevented from flowing and location of the gates. I use it on my D/SP Integra, B17A1 for Solo I, II and lapping days. I have never experienced oiling problems before or after changing to the Moroso pan, just cheap insurance.

Thanks guys. I have the Moroso pan on my car now, but had heard the same thing about it being built for drag purposes. Just wondering if anyone had bad luck w/ it under road race conditions. I guess i'll keep it on.
Thanks for the fast response,
Jeff

 

the mugen unit is a stock unit with baffleing added inside. nice quality. look is OEM, but does it cure starvation? i was under the impression that morroso makes 2 units. one for drag and one for racing. seems that it would be sub optimal to design for both situations. best is to call and ask to get the right info

FYI -

high-G, sustained left handers can starve the oil sump if your oil level is low. for track days make sure you check your oil before every run. low when youre racing means anywhere remotely near the bottom dot on the stick when hot. better to be above 1/2 way. for longer races/open testing days, best is to run a catch can and overfill 1/4 qt and double check at every pit stop.

there may be other situations where starvation can occur, but in the case of sustained high-G left handers, im not convinced the mugen pan will do the trick. i remember thinking to myself when i had one in my hands that it would prevent sloshing (quick splash), but not starvation due to a sustained high-g turn because the baffles look to be designed to control splash not oil location. this is my opinion. others will dissagree. it one of those things that you buy as insurance. everyone i know who runs one, has done so without problem, but there are a good many folks running without that seem to do fine.

 

To add to DN post: If you have vtec engine, do not let your oil get low! The vtec system is actuated by oil pressure. Guess where the oil is pulled from? You got it, the same system that lubes the crank, etc. If the oil is low, you can damage other parts. I have personally seen a B16 self destruct. It froze a piston & sent a rod thru the front of the block.

 

Just to add.....I have a friend with a '00 Si that broke apart a rod bearing autocrossing. He was about 1/2 quart low and there was a long, fast left-hand sweeper. He is now building a 5th Gen hatch with a B18C5, and will not put anything but a baffled pan on it. Too bad most rules don't allow one.

Yes, My car with a H22a motors will even cut off hi-cam sometimes due to oil starvation.. I have to overfill it by 1/4quart to stop this from happening.. I am going to purchase another oil pan and put baffles in it.. Or might just call moroso and see if they offer one for road racing..

 

I had this problem at Sebring this past weekend when going through a few long sweepers I have never experienced this before and was wondering what is the best option to take care of this problem. I have a B18C and I want to do it right the first time, I don't know whether I should invest in a bettter oil pan or an Accusump system or both?
