edit: Picture attached. Stock crank pulley and bolt with Eibach bar. I was actually planning on shortening the crank bolt at some point because it was a little too close for my comfort.

I'm not questioning the experience behind the sump setup but I was thinking about this the other night and I'm wondering if having two pickups in the sump is a potentially risky option. If either of the pickups can grab air instead of oil then the pump might suck only though that one and not pick up oil from the other. This means you need to make sure both pickups stay well covered in oil which is hard when they are on opposite sides of a sump even with the best baffling. In a multi stage dry sump setup it makes no difference as each stage is sucking independently and you also have a swirl tank to take out the air, but on a single stage pump you're risking oil pressure loss during high G cornering / braking.

I'm sure your already doing this but I think you really need to find some way to proof the oil setup when you first run the car. Maybe an oil pressure light on the dash / careful logging and slowly building up G's on the track.

While Id like to get a better understanding of the inner workings of that system myself, Im pretty sure John wouldnt let something like that leave his shop.

90-93 cars mount the FSB further back in the chassis. Deviate is a '95R, so it will have more clearance between engine pulleys and the FSB. I don't know what the exact difference is in the locations, but I do know the 1.8L cars locate it further forward.

We did move the sway bar.

I think we have it covered but thank you for your concern, and skepticism. Not our first rodeo

Those are some pretty parts. Looking forward to hearing them in action.

Mind blown!! I didn't know this, I was curious why my fm away bars fit different on my 93, when they fit fine on my 94. I dismissed it as tweaked mounting points for the end link on my V8R tubular arms. The end link hits the coilovers in the soft setting. I guess this means I have a excuse to upgrade to a racing beat tubular for my year.

Looks great, thank you for posting. Nicely engineered and built, I like the flapper doors.

I was wondering what you meant earlier when you said there were 2 pickups on the pan. Does that single tube have two openings or is there another tube somewhere?

Where did you get the trick bracket/clamp for securing the coolant return pipe to the passenger side shock tower? I may need one of those for my coolant return hard pipe.

This is awesome. I saw a mini with a honda swap and ITBs it sounded amazing and might be worth it just for the sounds.
