I run a mitchell motorsport sump on my race car, had no issues over 2 years of racing. They are pretty much a copy of a much more expensive sump.

where can you buy them from?

thanks for that, i did read that days ago

Wait whTs better Abt a twin scroll sump over a single scroll sump?

Is it baffled from factory?

Slightly off topic but , I looked at a baffled sump when I did my rebuild , I discussed it with several people that build hi-performance engines and spent a lot of time researching different options and pro\'s / con\'s of various sumps.

End conclusion , for the $$ spent on a baffled sump there was little to be gained over the stock sump and every potential of creating more risk of oil starvation.

I ended up fitting a twin scroll sump kit which is a vast improvement over the single scroll item.

Just my opinion from my own research. ;D

I think it is just that the bottom half is narrower, so you\'d expect the oil to be deeper in the bottom? It does beg the question however, do group N cars have baffled sumps? Because you wouldn\'t bother if \'there was little to be gained over stock\'. Perhaps group N rules forbid sump alterations.

this is what i run

http://www.trademe.co.nz/motors/car-parts-accessories/subaru/engines/auction-609774713.htm

increased capacity to 6.5L, plus a 1 L in the oil cooler, filter, lines etc.

only done about 300kms of racing on it but seems good , just a cheaper option that still gives you some gating and extra capacity. to be fair i rally my car so the G forces arent as big as track with semis or similar etc etc.

I have one of hose in my shed not fitted yet.

I know a few guys on here run them with no issues. However my theoretical concern is being deeper but the Oil pickup being the same length as before means if you run low theres more chance of picking up air and not oil?

FWIW, I\'ve had a MacBilt sump for over 9 years in the GC8, after lunching a BEB at Manfield in 1994. This sump has been nothing short of awesome. The car\'s done 7 yrs at Manfield at InterMarques and Road and Track days, a solitary Pukekohe day, and several Taupo days - all tracks.

This is a well-proven sump for my car.

This car still has the same rebuilt engine that the MacBilt sump was originally fitted to at the same time as the rebuild, and has done 3x full logbookfuls of MotorSport events. I cannot recommend sump highly enough.

[rex-leggy]

after reading that i would go with the macbilt

just so everyone knows from what ive seen Al wouldn\'t be taking the corner slow either

[AdamOst]

Yeha im leaning towards macbuilt, but i spent all my money so will pick one up in a couple of months. Did you just get the default one or modified al?

[albaru]

Just the std one AdamOst.

[hijacka]

Can land a killer b set up for less than 1g nzd http://www.ebay.com/itm/Subaru-Killer-B-Motorsports-Optimal-Oil-Pan-Kit-W-Pickup-and-Baffle-STi-WRX-LGT-/300831844824?pt=Motors_Car_Truck_Parts_Accessories&hash=item460af9a9d8&vxp=mtr

Not sure how it stacks up against others but was looking at going this way for my build.

i dont think the base is any lower than a standard sump so shouldn\'t be any bigger gap than standard. and with all the extra oil, 2L extra over standard, the chance of running low should be somewhat negated?

[Johnnynz]

Hmm, I will measure it vs. A stock sump but I am fairly certain it is deeper, and certainly wider at the sides therefore the extra two litres would be in those sides.

If I\'m wrong and its the same depth then all makes sense but if its deeper I still see the same issue. Either way probably still better than stock.

I will try find 5 mins to measure tomorrow and report back.

[slydog]

They are the same I had the same thought when I got mine John. Just looks bigger

[loner]

I can\'t see how that cheap one would work... no extra baffling and more space for the oil to escape to.

[slydog]

They are not just winged they are also gated too. Cheap doesn\'t always mean crap. When I was looking into sumps when building my engine over half the guys don\'t run them they just run the extra 1/2L of oil . Madmike runs std sump and good times on the track and havnt had a problem yet

[Johnnynz]

Just stuck my hand in the one in my shed and yeah gated both sides.

[slydog]

Even Keith runs a std sump on the rally car. Or maybe he\'s to old to go fast now lol

They don\'t have any sort of surge tube around the pickup. So the extra capacity may offer some benefit but I don\'t think its going to offer much in the way of surge protection over the standard sump. Even a factory twin scroll sump would be better against surge imo.

same thoughts here, the only one I\'ve seen was off a car that ran a big end at Hampton downs on street tyres, don\'t know if that was the cause but it obviously didn\'t help!

I didn\'t actually say cheap meant crap, though to be honest, it very often does.

[Johnnynz]

What do you mean by a surge tube?
