V8 Into B5 II.
--------------------------------------------------------------------------------
So with my B5 A4 Quattro Sport, I proved the V8 does fit the B5 chassis, with minimal effort.
Following the success of Outlaw's new V8 heart, I have the pleasure of doing another V8-into-B5 project. Oddly enough, it's another widebody, this time though, the project is different - it's the same AHC S8 32V motor as mine, but there the similarities end.
It's a front track, it's retaining the original 5-speed 012 tranny, and it's going to maintain the OEM S8's Bosch Motronic ECU and harness, which means no MAP sensor, and it'll be running the standard MAF.
The base car is a Ming Blue Pearl 1,8 T Sport. I spent the day prepping the bay for the larger block, removed the 1,8T motor. Mounts are already available for the V8 / B5 integration, it will also be running one of my flywheels, a single-mass 7,2kg unit. In my car, there is no chatter, even when loading the tranny from low speeds, in any gear.
I'll keep you guys updated via the usual write-ups and pictures, stay tuned!

I think it'll handle the power in a very smoky way
This is the lunatic fringe I was talking about in the V8 thread in OT. I love the mad-scientist stuff. Siena, how aggressive is the timetable for this conversion? Fast enough for weekly updates or is that too ambitious?

Side note: These are old pictures, before the current owner got his mitts on her. She looks very different now - no RS4 badges, now sporting 1-piece ecodes, and M3-style trunk lip.
The teardown began today...
Outgoing 1,8T engine:

And so the teardown continued:







Little boy 1,8T:

Big bad boy S8 32V!


Fancy kicking that big lump into the B5 bay?

Similar, though S8 motor has a higher redline - 7,000rpm, and solid tappets on the exhaust camshafts to cope.
Throttle body and intake plenum are larger than A8 / A6 4,2L, and CR is higher - 11,5:1.
