For those of you that are road racing/track day'ing an H22 powered car, which oil pan are you using? An OEM baffled pan, the Moroso pan or something else? Under long left corners and some side to side transitions, my Prelude is starting to have oil starvation issues even with running a little extra oil.

As always, thank you for your help!
Brian.

don't know of anyone who makes a good one that works. Most of us H22 guys have to use OEM with custom baffles. FYI. the Moroso one does NOT work, it's really more for drag racing.

If you do find someone who makes them please let me know! Mine works ok, but I still get starvation from time to time.

Hey Walt! From what I have gathered, the later generation Moroso pans are better for both drag racing and road racing. However, I have read a lot from 2003-2006 about people that had issues but nothing more recent. Have you tried one?

I lost a second motor in my road race car this past weekend so I just ordered a Moroso pan for my Prelude today.
I also plan to run an accusump for added insurance.
I will let you know what I think of it when it gets here, I will be suprised if it doesn't look good.

accusump here. But only after melting the bearings, crank, and rods in my h22

mugen22

Please do keep us informed! What generation Prelude do you have?


If you don't mind me asking, how much did that setup cost?

Thank you,
Brian.

I have a 92 Prelude Si that I race SCCA E-Production.

I just noticed King Motorsports in your signature, you should talk to them as nobody knows more than they do about road racing Hondas!

I´m also very interested in that topic ... please let us know if somebody knows something ...

Its not that bad, I got the 2qt bottle, 7' stainless line, manual valve, block adapter, fittings, and oil pressure gauge for less than $500

Are you saying you did custom baffles? Have any pictures of what you did and where you got that parts?

I have been concerned with oil starvation too and have not been able to find much information out there on upgrades to help.

After doing a lot of asking around, some research and more asking around, I decided to give the Moroso pan a try. I haven't officially finished the install yet because I decided to clean my header since half of it was off the car anyway!

Moroso Pan Good:
Nicely constructed
Fit the motor with no issues
Oil pickup is huge
Oil capacity is huge-easily holds 6 quarts of oil and will likely need more once I fire the motor
Drain plug is magnetic
The squared off sides should keep oil where it needs to be
The "trap door" opens under acceleration allowing more oil to flow toward the pickup. This seems to be when the OEM pan struggles.
Better ground clearance

The Bad (applies to H22a4):
Walt is correct about the fitment. Not the pan, but the clutch cover/stiffener requires a lot of trimming, shaving, grinding. I plan on emailing Moroso my photos and concerns as all they need to do is make that end of the pan 1/4" shallower and it would be a non issue.
The pickup only uses 3 mounting bolts instead of 4 like OEM. This is more of a concern than a negative.
Cost. For as much as it cost, it should fit like Mugen!

Looks a lot like the z10 pan i used to own, pick-up and door/baffle setup... Good luck this time.

any updates on this??

DO NOT BUY THE H22 MOROSO OIL PAN FOR ROAD RACING. I am sad to say that it is worse than the H22a4 OEM pan. At the track Monday, VTEC cut out more times and for longer durations than before.

The reason I hadn't updated this is because I wanted to contact Moroso first to see how they handle the situation. Oil level was good, oil was new, VTEC solenoid screen is clean and it only does it on long left corners. My oil light did NOT come on but I do want to check my ECU to see if it shows a code 22 for VTEC malfunction.

So in the meantime, DO NOT BUY THE MOROSO H22 OIL PAN for road racing.

I wonder if you put a horizontal baffle on the right side of the pickup if that would help keep oil from sloshing to the right side of the pan on left turns...

I had one as well, but ended up sending it back due to fitment issues, and I mentioned to you already. The other thing I like about the OEM pan is that it bolts securely to the engine stiffener. Too bad no one makes a direct 5Gen replacement oil pan that is road race ready.

Update 8-26-2011:
Do NOT buy the Moroso H22/H23 oil pan 20912 for road racing.

I spoke to Moroso and they confirmed the pan is designed for drag racing. WTF?!?! I mentioned to their tech/customer service guy that the description on Moroso's site states, “Whether you drag, oval or road race, Moroso has the pan your engine needs..” as the description for Moroso oil pan #20912. Please see the screen capture below. THIS PAN IS FOR DRAG RACING OR STREET USE ONLY! Why does their website list road racing as one of the pan’s uses?

Moroso has offered to add a shelf to try and make my existing oil pan work, but at this point, I don't know how many more chances I want to take. I am leaning toward finding a way to modify the OEM pan. Sucks to have my season end early because of a generic product description.






Keith, did you ever install your oil pan?


That is sort of what they are talking about doing but this oil pan is pretty shallow versus a stock pan. After looking at their B series road race pan, the baffling is much more obvious and the depth of their pan is the same as stock. I don't think there is anything they could do to save this pan. The could make the left side (the side with the kick-out) deeper and add a trap door that opens laterally, but I was told, "that would be very expensive because of engineering time." At this point I am sort of sitting back and trying to figure out a game plan.

Are you still running a factory pan? Did you modify it at all?

Thank you,
Brian.

I'm running a 100% stock oil pan. I just over fill it. Not optimal, but I haven't found a better solution.

I thought about milling the lower part of the OEM pan off and having a new sump welded on with kickouts, but I haven't gotten around to it.

mugen22

How much do you over fill it? I used to add about 1/2 extra quart beyond the full dot on the dip stick.

The Moroso webiste still really bothers me but I guess it is really my fault. I should have realized that a product description that says, "designed for front or rear wheel drive" and, "fabricated from aluminum or steel" is as generic as they get! That said, if it is a drag race pan, than they have no busines saying oval and road race anywhere in the description. Ok, moving on.

I have been doing a lot of reading and there are a lot of interesting baffle kits out there for the K20/K24 and F20C that may be my motivation. The OEM pan has spots where brackets could be bolted internally and the baffle could be mounted to the brackets. I will definitely consult with you and the guys up at King about it. Then the decision comes down to aluminum or stainless, bolts and/or rivets...

BTW, does anybody know where I can buy a new engine stiffener/clutch cover? Majestic doesn't show it anywhere.

Thank you,
Brian.

I think I've gone as high as 3/4 to 1 quart, but it's been a couple of years since I've had it on the track.

Thanks Billy! Seriously, it was under Alternator Bracket?!?! I don't think I would have ever found it.

I have it on my car but my next race isn't until November 5th.
It's too damn hot here in Phoenix!
Who did you talk to at Moroso?

mugen22

PM'd you!

I don't want to call out this particular guy because he was at least responsive and attempted to accommodate me. Keep us posted with how you do!

Thank you,
Brian.

Something as simple as this might work:

I'm taking the car out for the first time this weekend.

I give a second vote to just install an accusump. I run with the 2.5qt version in my road racer. It solves all starvation issues even in the most demanding left turns. Some cars the oil pumps are not strong enough to fill the accusump again, but the H22 is not that engine. I run the stock pan, in long enduros, and it works great.
