Luis brought his 1992 Nissan Skyline GT-R in for some in-depth maintenance and to have the whole setup dialed in on the rollers! Up first, we were tasked with diagnosing a low oil pressure condition — after inspecting everything possible outside of the engine (including oil for signs of bearing material/wear metals), we concluded that it was almost certainly what always causes low oil pressure on a factory-sealed RB26DETT: rear housing bolts on the oil pump backed out, causing internal pressure loss. And that’s precisely what we discovered!
Up next, we reassembled the engine with brand new OEM Nissan timing components, N1 oil pump, N1 water pump, and all the OEM Nissan gaskets & seals to complete the installation. With the mechanical work wrapped in the shop, the mint-condition NISMO LMGT4 wheels came off, the stock wheels went on, and then she hit the rollers to get dialed in by Vlad via Haltech.
With N1 turbochargers feeding 18psi, Vlad was able to increase power output to 444.31whp & 375.02lbft on 93 octane! Solid results!
