There’s two engine swap options that tuners use to obtain the highest top speed for the Goliath; they’re the 6.5L V12 (Aventador Engine) and the Racing V12 (Ferrari F50 GT Engine). Some argue using the Aventador engine since it gives you a higher acceleration, while others argue the F50 engine for the top speed. Is there any definitive answer for the fastest lap time?
I just tuned this car a couple days ago. Definitely go with the stock engine. It’s a little heavier but you can do more with the extra PI. I built an S1 tune with both engines and ran Goliath. It’s a handling car, so put more suspension into it, you’ll be glad you did.
