Confirm - no reason I can't put an inertia ring gear on a verto flywheel backplate?
Turbo Mini Forums

I'm pretty sure that all ring gears are the same ID and the axial location is the same for verto and pre verto? Looks like the verto ring gear is approx .450" wide, and the "thin" inertia rings are .50" wide.

I'm sure if anyone asked me this stuff 10 years ago I would've known the answer… im getting old

yep it'll go straight on, Ive done it.

keep an eye on starter engagement tho as one of the ring gears is a bit narrower IIRC and some after market flywheels can be machined a bit different.

Good stuff. I've a stack of inertia starters that need using before I go and buy one of these fancy pants inline starters. My intercooler pipework is in the way of using one of those with the solenoid above the starter, and obviously the intercooler is in the way of the factory pre-engaged starter...

Both of my early MG Metro Turbo engines came with inertia ring gears and starters.

I think some of the first verto setups were inertia anyway ?

Although how you'd go about finding one of those flywheels now is another matter lol

9.85 @ 145mph
202mph standing mile
speed didn't kill me, but taxation probably will

Yep, I didn't know about the very early metro turbos, because I've never seen one in person. I guess the turbos got the Verto clutch from day one, and it was later rolled out to all the metros.

I have some and before you ask no

Own the day
