The engine is a surprisingly snug fit all around. With the headlights removed, it's easy to drop a camera into the engine bay with the hood closed to check engine clearance. The cam angle sensor is the closest point to the hood and clears with a just-comfortable-enough margin.
The clutch slave cylinder was a completely unanticipated near miss. The bleed screw is so close to the Hayabusa's oil passage plug we actually had to remove the bleed screw's rubber cover!
The clearance between the oil pan and the subframe is very cozy here. This is one of two areas we would have designed differently if we built our own subframe, just to give ourselves more breathing room.
This is the other tight spot that we would have done differently. The main cross tube is directly under the lowest point on the Hayabusa engine. To address this challenge, our subframe would have the tube a little farther forward, under the steering rack.
In the end, even though it is tight, it all fits with the V8 Roadsters subframe, so we'll stop complaining.
Things are getting seriously close now. It's all details from here on out….
