Actually UCF-10 isnt 1UZ-FE
U means 1UZ-FE
C means C class (top spec)
F-10 is chassis (F meaning celsior I think?)
Feel free to correct me
U = UZ-powered
C = 4-door saloon (luxury), I think
F = ??
10 = coil suspension (at least it does here - Oz - and in Japan
11 = Air suspension
I've included a brief chart showing the JDM-Celsior grading system for the Celsior - this may assist.
1 A specification Sedan 4550* FR AT G 4.0 1UZ-FE E-UCF10-AEPNK
2 B specification Sedan 5300* FR AT G 4.0 1UZ-FE E-UCF10-AEPGK
3 C specification Sedan 5500* FR AT G 4.0 1UZ-FE E-UCF11-AEPQK
4 C-Fspecification Sedan 6200* FR AT G 4.0 1UZ-FE E-UCF11-AEPQK(F)
The following link
http://ourworld.compuserve.com/homepages/stepho/newcodes.htm provides a basic run-down of what the various parts of the model codes mean...
From that site your model code would be as follows:
A = Model type (Saloon)
E = 4 door sedan
P = 4-speed, floor-shift automatic
G = Higher grade, general (refers to appointments/trim levels)
K = twin-cam, EFI, economy engine
A = Destination, in this case USA.
Hope this helps.
