4G61 Swaps 4G63...

[RY83NA]

I have a 91 GSR and it has a 4G61 motor in it im thinking of putting a 4G63 motor in it are they the same engine mounts and harness....????

Have a look at CBGSR's thread, 4g61 and pumping out over 230kws now.

Can use same harness, i used a CB GSR engine loom on mine, had to add knock sensor, and air temp wire to use on VR4 ecu.

I am also interested in this swap. I have a mate with a 90 gsr that the timing belt is gone . I have a spare vr4 engine without the turbo. I might lend to him while he decides what to do. I was thinking of just putting in without the turbo and bolting the 61 intake and exhaust to it.

I was told that the engine should bolt on the same mounts.

Any info would be great.

Remove 61. Replace with 63. Skids... pretty simple.
