Well progress has been made!
I pulled out the old G52 which you can see in the above photo, as it turned out its even got a complementary hole in the side of the bell housing. The other thing I noticed is that somehow a tooth has been broken off the 22R flywheel which perhaps explains the occasional disinterest in cranking the ute had. So all in all I'm glad to be rid of both the 22R and the G52.
Anyhow I went about test fitting the 1GGTE using GA61 mounts and as expected the drag link fouls the sump, no big deal just give it a bit of hammering. What I hadn't planned for though was the handbrake pulley (that little thing sticking out of the firewall below the clutch master) getting in the way of the rear turbo inlet. Funnily enough also the clutch master fouls too. Luckily though thanks to a member on Toymods I was alerted to the fact that VZN130 4runners (V6 ones) actually run an internal pulley on the handbrake cable so its not there on the firewall at all. So I had a look into a 4runner and sure enough he was right, not only that but they also have an internal clutch master and a remote reservoir. Bam problem solved!
I think its a fitting time to start up a to do list also:
There is more, but I'll update it as I go.
