do you remember how you got to that number?

@1jzjohnson
Sorry for the late reply, my had died since I uploaded the mod.
So, to make this kind of mod, you have to edit the engine scripts - Under ( parts/engines/einvage_duhen_ishima_.../src). In the SRC folder you have to edit each engine part seperatly.
This way you can edit the price, (virtual) cylinder number, the number of valves, bore, stroke, Boost for the turbo.
Basically it is messing around with numbers untill you get the result you desire.
All you need is notepad, and checking other engine types also helps.

good mod but for future mods you do you should tell people how to do it in the discription
