GT-R Restoration



For last week, I decided to work on the R33 for some minor tweaks here and there, it probably needed some small upgrades but with better parts.

The normal RB26 engine is well known for pump related failure and this was also the case. So I decided to replace several parts that came directly from Japan.



But first, I replaced the R32 wheels with the R34 wheels in the storage, and the Cusco front and rear bushing sets (V$ 400) were replaced as well.

The engine mount and the transmission mount kit was also replaced with Nismo ones (V$ 200) for better stability.

The brake pads were replaced with Nismo ones for V$ 150, as well as 2 bottles of MOTUL RBF 660 brake fluid (VS 50) were flushed.



The idle was quite not good after a long test run, and I replaced them with NGK Nismo ones for V$ 250.

The coolant system seemed okay so I decided to flush and replace the radiator and the catch tank later on.

The battery was replaced with Optima yellow tops (V$ 150) and the oil was drained in order to work on the turbo setup with some replacements.

The oil and the fuel filter was too old, so I replaced it with HKS 68mm ones and the OEM one (V$ 40), and I took out old manifolds and the turbo, and scraped the old gasket out.

Greddy T88 Turbo with Greddy Manifold seemed to be a pretty good option for what I could get, and I didn't need 4-figure horsepower at all.

The installation was pretty okay, compared with PITA twin turbo disassembly. All of the parts were fitting pretty well without any issues.

The notorious air flow meter was also replaced (V$ 300), alongside with Tomei fuel pump (V$ 450) and the timing belt (V$ 150) for more reliability.

Tomei Poncam Type-R Sets (V$ 600) and the adjustable pulley (V$ 250) was also installed!



I also copped the old Nismo exhaust system for V$ 300 from a local community.

The exhaust pressure was also an issue, so I had to get one to get rid of excess pressure to prevent power gain.

The engine runs pretty great after the map, and probably it needs better ECU tune somehow to achieve more balance. Needs more polishing!

I am planning to replace the transmission components and other parts that needs more strength.
