Higher Speed
After unlocking "Auto Modellista" you get to change certain car's engines. Since
when you change an engine your not allowed to tune your car here is a tip to get maximum
speed. As an example i took the Toyota Sports 800 and put in a 2JZGTTE. With just that
alone the car tops out at 165 mph. Go to tune and then pick "easy tune" do
maximum speed ++. this adds all performance parts to the car. After doing this i took the
Sports 800 onto Osaka Highway and got it up to 210mph and it was still going!
Fast car
The Nissan skyline, with a lvl. 3 reduction, full-turbine, racing muffler, a full-turbine
and a cpu chip and lvl.4 engine tune up, max out to about 565 horses. I was reading a
thing a guy posted about some, xjjx220 car that keeps going past 210. This car hits, 222
with just these things added!
note: I have tested and the skyline is one good car. The speed may be a little less but
it's over 210 and definitely near 220.
