Hey guys,
I was wondering if anyone can tell me if there is a different engine number sequence between the ordinary 155kW 6G74, and the 163kW VR-X 6G74. As in, there is something that distinguishes it as a VR-X motor. Reason I am asking is i am looking at doing an engine swap in my TE, and if i decide to buy a VR-X motor, i dont want to get ripped off.
For example,
155kW 6G74123456
165kW 6G74ABCDEF
Any help is greatly appreciated.
Cheers,
Chris:D

VRX engine is pretty much the same as the 155kw engine in the TJ apart from the exhaust.

Find a TJ engine, put a flow through exhaust on it.

nope as above, just a high flow zorst gives the extra 8kw

In the first series with the 150kW motor, there was a difference, the VRX motor had
different cams and ecu etc (from memory). The later ones with 155 adopted the VRX
engine.

The difference between the 147kW and the 150kW was a cam revision

The 150---->155kW upgrade was just a computer tune.

The VRX had the exhaust = +8kW (It also already had the computer tune in the Series 1 VRX thats why they also output 163kW)

This may not be the answer to your question but I quess it might help.

Did you try to email Mitsubishi in Adelaide and ask them. I don't think you will get answer to your question here.

Mitsubishi Australia does not answer question posted by the general public. Need to ring
dealer spare parts divisions.

if u actually buy a vrx engine, without the ecu or exhaust, and paying more because they say its a 163kw engine, then ur getting screwed, end of story ;)

Yeah was speaking to a wreckers once, they wanted $1500 for a Ralliart Engine they said it was 180kW, I said its really only about 165-167kW (180 - 8Kw for exhaust, 5Kw for ECU if not more coz its a ralliart, and a whopping 1Kw for headers) and he argued me on it, wasnt gonna buy it anyway so I wasted his time :)
