After seeing the absolute hell it could raise on Route X, I’ve started slowly tinkering with the drift LS swapped Silvia. My end goal is to make it usable to beat the WTC700 championship, as my build maxed out on the S14 and it just wasn’t fast enough on the first two tracks to make it happen.
So far I’ve only upgraded it with a custom transmission, clutch, racing brake pads, sports hard tires, wide body+offset, and racing suspension on default setup. I haven’t reduced weight or added aero yet.
I compared to a stock Qs and made note that there was no change indicated in the weight distribution ratio stat stock vs swapped, but there’s certainly an odd feel with the new engine with no power or brake applied. The engine adds 200lbs to the front, and from the major weight increase so far on one end, it’s adopted some characteristics that remind me of an RR car. At “low-medium” speeds (relatively speaking, given this thing can hit close to 270mph with barely any time spent setting up the transmission) off throttle it gives a sensation a bit like what RR liftoff oversteer feels like. However it’s more like it’s penduluming around the engine bay, with the front wheels gripping reasonably well and just not enough pushing the rears into the road. Adding light throttle balances the car a little, but slightly too much unsurprisingly snaps the rear, given the 1000hp power plant. A spoiler would undoubtedly assist massively, but I want to try some suspension adjustments to see how far small traction improvements go. In it’s current state feathered throttle and several gears too high is necessary to keep it on track in the corners.
Someone mentioned the part availability is tied to the engine, and I believe that’s true (or rather I think power upgrades are tied to the engine, weight/stiffness upgrades are tied to the body/chassis). The only power upgrade I have available is the high RPM turbo (though interestingly the engine swap makes a racing exhaust standard), and I have weight stages 1-3 and chassis stiffening available. I don’t have the drift car so if someone else does it’s be interesting what weight options ot has by comparison.
Another funny tidbit, the turbo, which would increase HP by around 160, would only add 0.4 PP. Installing rear bumper B added ~2.5 PP.

Obviously it doesn’t need any more power, but I will experiment with that eventually. For now I’m going to see how drivable I can make it bit by bit without just resorting to RS tires.
I think this swap is really only useful for a drift or drag build to the common user, and will pretty much mandate deeper tuning knowledge if you want to use it for anything else.
