sch seem obfuscated, there is just a "SDTE" at the beginning.
tech is clear and contains various float values, probably a model.

Can a script to extract and repack the file be created? or more i dont know files are required ?

iv double checked the quickbms script list there is nothing that works with these formats though.

Nothing can be done without information about the format and obfuscation.

You have been very lucky:

Both RES extraction and SCH decryption supported.

The script supports also to re-encryption of the sch files, the first time it generates a file with txt extension, edit it, then reuse the script on the file with txt extension, a sch file will be generated.

The second .zip is not, random files thats the game .exe and some files related to it i think that the setup creates upon installation, that is all like i said also i thought obviously since games usually store the format and file info inside the exe i thought it could be of use but at any rate...

Also that .tech in the first .zip has usefull game data iv know before posting here, thats why i uploaded it with the other ones thats why i need to get it unpacked or in some human understandable readable form , yes it contains the float values for gears,transmission,game physics engine,chassis etc and the other constants wich the game uses i think.

Exactly, random useless files containing no game data.

For the tech files instead try to open a topic in the 3d section but keep your expectations low, I really doubt there will be any 3d model popping out easily from there and the chances that someone will check it are very low.
Anyway, try :)
