Switching up Your Car Engine: Can You Do it in Malaysia Legally?

There are a few reasons why many change their car’s engine – it can either be because of car engine failure or simply to swap it out for a more economical or more powerful solution. If you are in the market for a new car engine, just like any other part of a car, there are rules when it comes to engine modification. In Malaysia, the Road Transport Department (JPJ) has set guidelines that you will need to follow when it comes to engine modification.

Check with JPJ Before You Modify Your Car  in Malaysia

Changing your car’s engine will require a visit to Puspakom and JPJ –  you must bring your car for a Puspakom inspection and get approval from JPJ as some modifications are illegal, while others may be subject to some hefty fines.  In general, a special Puspakom inspection, better known as the Puspakom B2 Inspection, is necessary for:

  • Private vehicles with road tax that has expired for more than three years
  • Modified vehicles (modification of car engine specifications, chassis, or vehicle body)
  • New or used imported cars that need to be registered with the JPJ
  • Change of Car Plate Number
  • Other requirements as requested by the JPJ

According to Section 12 of the Road Transport Act 1987, modifications made to any vehicles before or after registration must be done legally.  Additionally, your car may even be inspected by the Director-General at any time. 

How to Change Your Car Engine Legally in Malaysia

Now, let’s circle back to modifying your car engine. Here is a detailed guide on what needs to be done before and during your Puspakom B2 Inspection.

Types of Car Engine Change Application

There are various types of engine changes and with each type, JPJ has implemented these in specific categories. Here are the breakdowns. 

  • Category one: Engine change of the same make and capacity (cc), or with a capacity not exceeding 25 percent of the original engine* (private vehicles only).
  • Category two: Engine change of a different make or capacity that exceeds 25 percent of the original engine.
  • Category three: Engine change that involves fuel type change.
  • Category four: Engine change on Proton-made cars with Campro engines to Mitsubishi-made engine.
  • Category five: Engine change that involves changing of the gearbox (from manual to auto).
  • Category six: Engine change for commercial vehicles.

*The original engine refers to the engine mode installed in your car by the manufacturer when you first bought it. 

List of Engines that are Similar

When replacing your engine, you will need to research which engines are suitable or similar to the one you want. Here’s a list of engines that are similar based on the brands.

  • Overall Test: The overall inspection involves the identification of the registration number, chassis and engine, etc. The applicant will then receive a B2 report and a fee of RM25 will be charged.

Approval from JPJ (For Category two to six)

For situations that fall under category two to six, applicants are required to get an approval from the officer in charge at the Automotive Engineering Division before their car gets inspected at Puspakom.
