Do I need to upgrade my clutch?

Yes. The stock clutch won't hold the torque this build makes. We include a clutch kit rated for the power level. Skip it and you'll be replacing a burnt clutch inside six months.

Do the diff bushes need doing too?

Check them first. The factory rear diff bushes are rubber, and on a hard-driven Z34 they crack. Twin turbos put a lot more torque through them. If yours already clunks on and off the throttle, replace them as part of the build.

Will the VQ37 handle this power?

The VQ37 bottom end is strong. We've put this power level through them and they hold up fine when the tune and supporting mods are right. That's what this package is: everything the engine needs to run this power safely.

Why is this price on application?

Every Stage 3 build is a little different. Some cars need extra work depending on condition, history, and supporting parts already fitted. We quote the actual job rather than a sticker price that hides the real cost.

How long does the build take?

Usually one to two weeks. We'll confirm timing when you book in. You'll get photos and updates as we go.

A turbo kit voids the factory powertrain warranty, full stop. If your car is still covered, that's worth knowing upfront. We warranty our own work (parts and labour) but the factory won't.
