…and use a previously created I4 in it (very oversquare 2.3l family), but… surprisingly it doesn’t fit. Why surprisingly? Well, because I’ve played a bit with that body, and I know that it can fit much larger engines transversely. So I’ve made a quick test engine - as big I6 as could fit there, still transversely. Effect - a bit undersquare 2.5… longer than that I4 I wanted there. Like, WTF is this magic? (and yes, I tried reclicking the suspension - it didn’t change anything)
Well, I don’t know what exactly Automation considers when deciding whether engines will fit or not but that I4 is substantially bigger than the I6 in everything but length.
I know, but the arrows clearly show that it’s too long. I’ll try later to make some other engines with similar dimensions as that I4 and check if they will fit.
Making a new one would make more sense in this case. But still, I wanted to use this exact engine, which should logically fit there - and since it doesn’t, I’d like to know why, to not be forced to make new engines every time when such weird thing happens again and forbids me using an engine planned to fit somewhere.
Edit: as I wrote, I’ll try later, as I’m currently unable to.
Gearbox size is based on the size of the engine in the game. Since the I4 is “larger” (bigger displacement per cylinder) it will probably end up with a larger transmission.
There was a conversation on that topic among the beta testers a while ago and the conclusion was that IRL transmission size usually correlated with engine size, and that you couldn’t really correlate gearbox size with gear count or engine torque.
I’ve encountered a problem like this before, only it was with the head type. The engine with a SOHC would fit and even allow me to increase the displacement, but if I switched to DOHC I had to decrease the displacement to make it fit. You may want to try different heads on your new engine to see if that may be your problem.
I did two trims of the same car, same size engine, but the power and torque was higher.
Only things changed was: compression, cam, sport/standard intake(weight is the same),
fuel octane, air/fuel mix and ignition setting.
Everything else was the same.
So… the trans case size is based on the size of a single cylinder(like max/min size of turbos),
but the weight scale with the torque. Ok. Seems semi reasonable.
That is correct. Engine scale depends on mostly bore (the physical size you see the engine as). That is the scale that affects gearbox size, which is a limitation of this rather crude but workable system. Weight indeed is calculated with how much torque the engine produces.
