Project 240K

After receiving back the powdercoated parts, and waiting on a new set of idler/tensioners for the engine, i was finally able to put it all back together.

Unfortunately the photo’s make the grey look a lot lighter than it actually is. A 500HP ATI RB26 balancer was also used, though at the moment, i have not installed the front pulley.

Unfortunately the RB26 loom had been damaged at some stage of shipping, a replacement had been organised, but it would have been a shame to have thrown away an otherwise good loom. I researched into getting a replacement plug, but this as going to turn out to be as expensive as a replacement loom. After a look at the ECU schematics for the RB20/RB25 and RB26 i realised that all share the same actual plug.

I sourced a cheap RB25DE loom and set to work transferring the wires between them

The pins are released simply by inserting a needle into the loom, pushing the pins into the new connector allow them to simply click into place! The hardest part was keeping tack of the pinouts and getting them right. an ECU pinout was invaluable.

After a couple of days, and a couple of hundred dollars later, i received back my modified aluminimum sump. Luckily after the changes, the bowl still accepted (with some minor modifications) the Tomei Sump Baffle.

The original RB26 oil pickup was also used unmodified.

Whilst the engine was out to fit the sump, i also bolted up the RB25DET gearbox using brand new RB25DET mounting bolts/nuts.

I wanted to replicate in some way the original KPGC10, KPGC110 and Z432′s S20 engine scheme, and after a search on the web, i found the following which i liked

I decided that i would colour the plenum and twin turbo pipes in red, and the top and front engine covers in grey. After speaking with the powdercoater, i settled on a red textured coat for the pipes and plenum, and a metallic grey similar to the infamous Z tune R34 GT-R

After a couple of weeks, i had the powdercoated parts back.

Meanwhile, after measuring up the standard RB26DETT aluminimum sump , we cut off the front differential and driveshaft, and sent it off to an engineer to have the aluminimum plated and welded up.

Since i am planning to have the engine covers powdercoated, i got to work removing the plenum, camshaft covers and front covers. While doing this, i will take the opportunity to install new belts, idler and tensioner and an N1 water pump.

The condition of the engine looks really good, obviously it had been well looked after. I also found a set of HKS spark plugs, so i assume the previous owner spared no expense on the maintainence of the engine.
