ACT XT/Race Sprung 6 Pad Clutch Kit
ACT NS3-XTG6 is the Xtreme pressure plate and 6-pad sprung ceramic race disc combination for imported rear-drive Nissan Skylines: the 1989-1992 R32 GTS-T with the RB20DET and the 1993-1998 R33 GTS-25T with the RB25DET, both with the five-speed. If your RB is making real boost and the clutch now flares in third and fourth, or it lets go every time you launch on sticky tires, this is the ACT kit built for that job. It is not a daily-driver comfort clutch; it is the one you choose when holding power matters more than pedal feel.
A single-cam-turbo RB in an R32 or R33 makes modest torque from the factory, but a larger turbo, boost controller and fuel upgrades can push torque well past what the stock organic disc was sized for. ACT rates NS3-XTG6 at 630 ft-lb measured at the crank, which it lists as 123 percent over the original clutch. Two parts make that possible. The Xtreme pressure plate (ACT N013X) uses ACT's diaphragm design to raise clamp load and reduce deflection, and the 240 mm (9.4 inch) six-pad ceramic disc (ACT 6240306) keeps a sprung center so torsional vibration from the driveline is still damped. Ceramic pads tolerate heat far better than organic material, which is why the kit suits drag launches and track sessions. ACT describes the feel as moderate to heavy pedal effort with aggressive engagement.
Do a fourth gear roll-on from low rpm and watch the tach: if rpm rises faster than speed as boost comes in, the clutch is slipping. Before you condemn the disc, bleed the clutch hydraulics and confirm full slave travel, and check the bellhousing for engine oil from a leaking rear main seal, because oil will ruin any new disc. Our slipping diagnosis guide walks through the checks, and the flare vs slip guide explains how to read the symptom.
ACT lists NS3-XTG6 for JDM 1989-1992 Nissan Skyline GTS-T (R32) 2.0L RB20DET and 1993-1998 Skyline GTS-25T (R33) 2.5L RB25DET, rear-drive, five-speed. It is not listed for the twin-turbo GT-R or the R34, and swapped cars vary, so match your flywheel, the 1 inch input shaft and the 240 mm disc size to your build, or send us the chassis code and engine and we will check before it ships. More Skyline parts are in the rebuild kits and clutch section.
The XTG6 is the top of ACT's single-disc range for this car. If the RB is moderately built and still sees regular street miles, the NS3-HDG6 pairs the same style race disc with a lighter heavy-duty plate, and the NS3-HDSS uses a street disc for smoother engagement.

No. ACT lists it only for the rear-drive R32 GTS-T with the RB20DET and the R33 GTS-25T with the RB25DET, five-speed. Twin-turbo GT-R cars use different clutches.
No. NS3-XTG6 includes the Xtreme pressure plate, the 6-pad sprung race disc and an alignment tool. Buy a new release bearing and pilot bearing separately.
ACT rates it at 630 ft-lb measured at the crank, 123 percent more than the original clutch.
It can be driven on the street, but expect moderate to heavy pedal effort and quick, aggressive engagement. If most of your miles are commuting, the HDSS or HDG6 version is easier to live with.
Yes, if it is resurfaced and within spec. Many owners fit a lighter steel flywheel at the same time since the gearbox is already out.
