hi guys im currently doing a L18 into 120y coversion just wondering what gearbox cross member do i have to use to make it fit.


Cheers Mark

why not just put a turbo motor in?? a z18 would be nice

180b gearbox crossmember might work, havnt looked under the 120y for a while
but its not hard to make a gearbox crossmember anyway

yeah why not go a z18t, coz they are just everywhere
and its so hard to convert from L series to Z series anyway

use the A series gearbox crossmember, but just enlarge the holes slightly for the bolts that go to the gearbox itself.

thanks guys for your help

team_dat i assume you would use the a series gearbox mount also?

I'd perfer the L18

in a 120Y a Z18ET is a 100% increase in power

hmm as it happens I do have a 120Y with no engine and gearbox...

shame I don't know where there are any 180B's near the farm... otherwise I'd be going that way rather than A12 and F4W60L

but also saying that the things that need to be changed/altered to fit an Lseries in a 120Y is not a small list

yeh A series gearbox mount as well.

I have an L series convestion, and just made up a mount with some angle iron, it was as simple as pissing in a cup, worked well too. I used a 240K crossmember but had a lot of dramas with the sway bar, had to get a custom made one cost me $340.
