Had a 2009 Ariel - and after tricking out the Ecotec 2.2L S/C et al to 450 WHP, a Motec 800, Meth-Water injection, larger coolers, fans, pumps etc. and racing it every where from Sebring to Calagogie Canada - I decided to sell it. Oil capacity is 5 Qts. Just now running across a bunch of Atom parts in the shop that got buried behind the Nissan GT-R and the FF GTM stuff - so decided them put it up here on . All parts worked perfectly when removed from the Atom for the sole purpose of increasing performance. This is a NEW GM oil pan that I bought as a strategic spare when I had the chance. Brand new never installed. With the low ground clearence i was concerned that if I ever had an off - or did a little off roading there was a good chance that i would crack the pan - it is SOOO close to the ground and so vulnerable. But I always kept it on the track - never went Baja driving so - never needed it. I added a ton of details pics to make sure you get the right pan since I don't have a part number - I should look again. .
