Maaan... Lol... Just when I thought buying the modified oil pan would be easier... I think I'm just gonna try it the "noel" way and compress the oil pan... I'm hoping someone who just drilled the block without removing the oil pan will comment and tell me everything will be OK lol... So far, only person I know who did that is my friend,and (I'm assuming since he has it in his manual) @Bill from Hahn RaceCraft... Does Hahn ever get on these forums?
Yes. Go to http://www.hahnracecraft.com. Contact sales@hahnracecraft.com for questions about costs.
Here is a link to @rabtech's install from the old forum - RABTECH Hahn Racecraft Stage 2 Turbo project with instructions. Pure Sexy Finished with Videos. | Polaris Slingshot Forum. It's not a complete step-by-step how-to, but has some useful info. @rabtech removed his pan before he drilled his block to make sure no metal particles got into the oil pan. I figure it's worth the several hours to pull the pan for peace-of-mind whether you drill the block, weld a bung in your pan (requires pan removal/reinstall), or swap your pan for a pre-modded pan (also requires removing your pan, swapping pan components and reinstalling).
if you're nervous about drilling and tapping the engine block, ask your friend for assistance. Just remember that there are no guarantees as far as DIY installs.
Do you have the Hahn Turbo install instructions? It explains the drilling process and using grease to try and catch any drilling particles. PM me if you need a copy.
