Ah cool, glad it worked out. I didn't realise there was a swap for that car, I'm guessing RB26 from later Skylines?

It’s the LZ20B. It’s great in that little light car.

Notes: This car was decent stock, but I could have done with a little more turn in, and a little less oversteer on exit.

The Stock LSD settings were actually not too bad, but I preferred lowering them to make the exit oversteer more manageable

I have gone for an equal frequency front and rear – which is unusual for me, but it did feel marginally better than my usual front-biased style. Front biased frequencies and ARBs are in brackets should you wish to try.

600 PP seemed like the logical point for this car (550 would have required detuning). But there were many ways to hit 600 PP by either adding large turbo upgrades for huge power, or moving to SM tyres, or lowering weight. I achieved similar times on Deep Forest either way, which I thought would prefer the all-out power setup due to the long straights. But the braking zones became harder to manage and the back end kicked out unless very fine throttle control was used, so the power was lowered. SM tyres felt lovely with weight reduction 1 applied (1383 kg), but ultimately I went for wt. red. 2 on SH tyres. The suspension was still useable during any of these setups.

If you wish to put her on SM tyres then you’ll need to either reduce power via the ECU or add weight via ballast to keep 600PP. I recommend setting the LSD Accel to 15 on the SM tyres, they can handle it.
