Nissan GT-R VR38DETT Forged Engine by QT

In today's turbo engines, which almost without exception produce brutal amounts of torque, component durability becomes a limiting factor very quickly.

In the case of the VR38DETT — very quickly.

This particular engine was previously built elsewhere around 60,000 km ago. There were no major issues affecting its usability, but it was opened pre-emptively — and not without reason.

We encountered several things that were done a bit "oddly," which we explain in more detail on our YouTube channel.

Practically everything in the engine was replaced, along with carefully selected machining work.

• CP forged pistons for 95.5 mm bore

• Carrillo connecting rods + Carrillo rod bolts

• OEM oil pump

• OEM timing chain tensioners

• OEM head gaskets

• OEM full gasket set (every engine gasket and seal)

• OEM head bolts

• OEM crankshaft bolts

• OEM camshaft bolts

• OEM valve stem seals

• KING connecting rod bearings

• KING crankshaft bearings

Machining work:

• Cylinder head ports cleaned up

• Block + heads resurfaced

• Light honing of the block

• Crankshaft + rods + pistons balanced*

• Crankshaft main housings inspected

• Crankshaft inspected

• Valve clearance adjustment (solid lifters)

Other work done to the car:

• Linney inlet pipes

• Turbocharger service

• Stainless steel charge pipes

• Front differential service (incl. bearings and seals)

• Bellhousing bearings

• Injector inspection

• Triple catch-can setup (valve covers + crankcase)

• Wiring harness tidy-up

The project was carried out by QT Performance.
