In this episode of The Skid Factory we check out the latest upgrades to the JZS171 Crown Wagon and address one of the biggest problems with the platform. Al sold the car to his mate Brad after the exhaust, intercooler and ecu upgrades and since then Brad has had a bunch more work done at Golebys including a highmount turbo, head studs and gasket. It makes good power but getting it to the ground is now an issue with the factory open centre differential. The Internet told us that a diff from a Subaru BRZ / Toyota 86 will "Bolt in" so we sourced one from the local Subaru wrecking yard. The G series diff from the BRZ / 86 is a Torsen Limited Slip Differential and supposedly will bolt into not only the JZS platform but also the XE10 Chassis and possibly others! The "G series" Crown wheel and pinion can be swapped from vehicles like the MX83 Cressida MA70 supra and some models of the Toyota Hilux to change gear ratios but this isn't a simple swap. If you've done this before let us know in
