The "ULTRA" in the SAF are upgraded to the M-113 A3 standards,
with Detroit Diesel Engines producing 275 hp (previously of A2
standards and firing on 212 hp Petrol Engines) and changed Allison
Auto Transmission following the A3 upgrade programs available from
United Defense LP

While the ACV300 produced by FNSS Defense System of Turkey has the
same M113 platform but upgradable according to several different
upgrade kits available.
The ACV300 manufactured for the MAF has its engine uprated to 300
hp Diesel also from Detroit, as well as matching Allison
Transmission Gear Box.
Full air-conditioning and NBC protection is available for the
ACV300, but nothing indicates if the MAF version will include
this.
To all intent and purpose, the ACV300 would actually be identical
to the improved version of the M113A3 developed by United Defense
LP

The basic hull of the Ultra and the ACV300 comes from the M113
which is a Aluminium box; with add on laminate steel plate for
armor protection, and composite materials available to both
types.
See the following site for the FNSS work in Turkey.

While the ACV300 will probably be equipped with the Bushmaster
'sharpshoote' cupola armed with a 25mm gun, the ULTRA feature an
Overhead Weapon System featuring a 25mm Gun without a cupola, with
the gunner inside the hull of the APC/IFV.
