Differences between the galant vr4 4g63 and 1g dsm 4g63

[socalgvr4]

What if any differences from the perspective of the transmission, sensors on the engine, or ecu are there between a 1G awd DSM/Talon and the vr4?
Basically, if one were to swap the engine from a vr4 into a talon, what would be things to look out for ? (assuming the use of the 1g talon ECU in this case?

ummm... their pretty much a direct swap. just make sure all the splines on the drivetrain are the same. I do believe the intake pipe and battery are mounted in slightly diffrent locations tho...

Sensors ON the engine are all in precisely the same place. One or both of the brackets that go from the engine to the rubber filled mounts near the radiator and/or firewall are slightly different (i believe it's only one of them). Vacuum hoses and solenoids go different places. ECUs have different timing curves, and IIRC the G's curve is more aggressive. I think those are the only differences.

Just make sure it's from a turbo talon and you should be good.

Hmmm can you confirm this, perhaps elaborate? My car came with no engine, transmission, or tcase. I picked up the engine and all the brackets accessories etc from a 1g talon. If there is a bracket that is different which I have not previously heard about I would like to know before I start putting it all together.

 

FOR SURE, the mount bracket that bolts directly to the engine block for the front mount is different. Get one from a VR4 or Galant GSX. Otherwise, the engine won't sit at the right angle in the chassis, potentially causing driveshaft vibrations/alignment issues, cv shaft premature wear, and exhaust alignment issues.

Obviously later 1G's had a 7-bolt, which means many internals aren't the same. But VR4 into 1G this isn't really a problem, as the 6-bolt is stronger. The t-stat housing is different, the 1G's have a radiator cap built into theirs, in galants the cap is on the radiator itself. The galant trannies have a taller but weaker 1st gear. The intakes off of the turbo are different, the pipe that bolts to the compressor housing is different. Vacuum line routing is slightly different. But that's all I can think of.

Thermostat housing has an extra sensor on ours. Its in the rear and is an oh crap lets turn both fans on with 100% voltage were getting hot. If you want just run the said wire to a switch inside and connect it to the tunnel off the switch so if you want to turn on the fans you can manually. Oh and the GVR4 motors are from a man's car not some faggoty girlie mobile /ubbthreads/images/graemlins/grin.gif

I always wondered what that sensor on the back of tstat housing was, and to go with that, the AC temp switch sensor is mounted directly on top of the upper half of the tstat housing (where the cap would be for a dsm). That upper half with the outlet itself points out at a different angle than a GVR4, I believe a 2G dsm is at a more acute angle than a 1g, if I'm not mistaken.

The only thing I see wrong about this topic is, why are we talking about swapping a GVR4 heart into a dsm, it should be the other way around! /ubbthreads/images/graemlins/bawling.gif
