This mod is great, I love all the customization options. However, I believe this mod is a little unrealistic, at least when it comes to the 2.0 4 cyl. For example, when I try to recreate an engine such as a Honda K20 Z3, using the right parts almost always gives me way too much power. Almost double what I'd realistically expect from simple bolt-on mods.
I love this mod and infact use it all the time, its the most fun thing to just sit there and delve deep into an assortment of engines. that being said there is one issue i find with this mod which is the fact that adding a turbo to an engine does not add an intercooler to the car or changing the intercooler option in the engine does not put the intercooler model on the vehicle.
Previously i want to rate it 5 Stars, but i rate it only 4 stars bcz, the custom engine for the Roamer, and D-Series was a bit unproper, the engine looks fall to the ground and that's very annoying. Please fix it, and i'll give you five stars! Keep your good work!
