    Very nice bits, would be worth quite a bit all that mucking around! I have reservations about stroke, cams, torque delivery, longevity / reliability. Interesting comparison to LS3 w/FBOs, 25% heavier, 20% more fuel / displacement, 20% less torque, 25% smaller combustion chamber, 25% less stroke... is like a high revving HP only formula one engine in a car same size as Zeta.

    Gearing and trans tricks obviously helps it off the mark though. Would require a bit of rowing like a ricer, I don’t think it would pull that well in-gear say 3rd from 20-100kph. Or tow more than a carbon bike and a tray of skinny latte! Overall gobsmacking amazing effort, needs decent cams, stroke for the street. Only shame is to read that the lubrication issues can kill it less than 10k km, big end bearings.

    So while definitely cool little buzzy formula one thing with great sound... big financial risk and over complicated vs LS3 w/FBOs. Like a Jag V12 or the NSX V10 in that regard, probably find a bargain around for obvious reasons. In sum nice legs, shame about the face, as a keeper I’d buy one of the dozen or so crapped out ones on car sales and do an LS swap!

    Yeah nah I understand about having docile manners and smooth takeoff. My trans is tuned to takeoff in second unless I plant it, has 2.92 diff. As a result the most important characteristic is off-idle slippery fluid coupling (TCC) and mild acceleration with cam fully retarded sometimes 4 cylinder mode. That’s like 50rwkw takeoff to 30rwkw at cruise! Thanks for posting, given me a great insight as to the nature of the engine and why.

    Yeah that’s what I did while it was out on bench overhauling lots might as well swap pistons, rods and add variable valve timing and ARP etc - 14:1 CR 6.1l high squish smallest chamber - 640 BHP. All race engineered by top firm cost less than $10k. Quotes for your four cams alone are $2.5k same to fit! Stroker will be same, so reckon add $15-$20k to purchase price and you’re sweet as... a supercar (or a late model hot Commie)!

    Very nice car The Stig. I've always prefered BMW over Merc personally. Although, some of the later model AMG's are pretty cool. What's it like to drive around town? It sounds like it might be a bit peaky? I went for a spin in a new M3 back around 2005. It was pretty cool for a N/A 6.

    I certainly wouldn't call it 'peaky' under any circumstance. It has a split personality though, differentiated by either the press of the 'm' button or use of the exhaust remote control. It's a fast car in 'relaxed about town mode', it tries to rip your face off in 'm' mode. I've added a graph above for your reference.

    Impressive. The tq curve demonstrates what i meant by peaky. Sweet spot at 6k rpm. Then steepish decent. But, HP ripping your face off by that stage. Hence the mask? Haha
