Car Importer

Build the car as it appears in Forza. Choose its upgrades, add motor swaps, then share it with the team.

1. Start with the car

Year, make and model Starting class and PI

Read the stock car's PI in Forza before installing upgrades.

2. Motors and conversions

Start with the stock motor. Add each available motor swap, then select it to fill out its upgrade tree.

Motor you are entering

Add a motor swap

Base aspiration

Add an aspiration conversion for this motor

Aspiration you are entering

A motor swap can already have a turbo or supercharger. Enter that as its base aspiration instead of NA. Additional conversions unlock their own turbo/supercharger upgrades. A different motor needs its own tree; unchanged parts on the same motor stay shared across aspiration conversions.

3. Check the available upgrades

Enter a motor's normal upgrades once. When you select an aspiration conversion, add only new or changed parts. Unchanged parts are shared automatically; other motor trees stay saved when you switch motors.

Engine upgrades entered now require the selected aspiration

Use this for turbo/supercharger upgrades unlocked by a conversion. Leave it off for parts that work with every aspiration on this motor.

Keep Stock checked when Forza shows it: Stock is the base state and never rolls as a reward. Uncheck it only when the actual upgrade menu starts at Street, Sport or Race. For a part removed by a conversion, choose “Not available with this conversion.”

Add an upgrade not listed above

Category Upgrade name

It uses the selected motor and aspiration setting if its category is Engine. Enter its options below.

4. Review the car

Expand an upgrade to edit its options, base state, or prerequisites. Tier 0 is the base; higher numbers are upgrades. Different options at the same tier are sidegrades.

I checked the selected options, base states and prerequisites against Forza.

Community Cars are shared on the website for hosts to select. They stay out of random selection until reviewed. Existing reviewed cars cannot be overwritten. Downloads are optional backups.
