Hey guys,

Just putting this expression of interest out there for a long block.

The engine was built by Advan Performance Centre in NSW and was a no expense spared build.

The engine is a 1996 S2 RB25 and was rebuilt with the following specifications:

BLOCK

- R34 GTR N1 crankshaft to bring engine capacity to 2.6L

- H beam Carillo connecting rods

- Mahle forged pistons

- N1 Oil pump

- N1 Water pump

- ACL Pro Series bearings

- New welsh plugs, gaskets etc. done during build

HEAD

- HKS metal headgasket

- HKS 264 degree intake and exhaust camshafts with VCT removed

- HKS Cam gears

- HKS Valve Springs

- HKS Timing Belt

- New seals, guides, valves etc. done during build

- Oil restrictors

- ARP Head Studs

- Machining, porting and polishing all carried out by Advan Performance Centre

This is a big HP engine built to withstand the 700HP and 8000RPM limiter is runs all day long. Engine has now done just under 20,000km and is healthy as ever. Only ever run on Motul Chrono 10W40.

* Currently the car is making between 360-390rwkw on BP98 on 1.5-1.6BAR of boost pressure through a GT3540R in a R33 GTST. The car is an absolute animal when it comes on and is a real handful to keep straight.

The engine is still in the vehicle so can be test driven if required. I'm hoping not to pull the motor out until I have a buyer interested but will see how I go.

Asking $8000 for the long block but I am open to reasonable offers if the price doesn't seem fair.

If some one wanted the complete engine setup with manifolds, turbo etc. I would be open to discuss that as well.

The car has run a low 11 second pass with this package in street trim on a shitty track. Put the engine into a VL or a S chassis and you have a 10 second car.

Any one that has done an engine build like this through a well known workshop knows how much money gets put into these builds and the brand new parts alone are worth more than what I'm asking for the engine so I think it is fair.

If there is any more info I can think of I will update the thread. Just quickly writing it up so I may have missed something!

Thanks guys.

Phil

Will give a free bump as well. Seen this package in its early days after build and it sounded like a f**king mental angry chainsaw on crack! Would be a perfect buy for someone looking to save a few dollars

      @Butters I can't tell you why but the bigger HKS step 2 cams improved low and mid end immensely. Turbos started spooling about 1k RPM less than before and the idle/vacuum was rock solid, it was an absolute thrill to drive, 3rd gear pulls hit 180kmh where previously only managed 160. Conversely, the milder poncoms in there now have a funky idle making it harder to get off the line, drives poorly in lower revs, laggy and makes less power/torque throughout. Feels better after I swapped the EBC but unless I put it on the Dyno again, I can't say how much better.

      Hi Sydney kid   do you still selling spring and blistein shocks for Nissan 260rs? Air any suspension upgrades? Please advice     yudy

      Cams are not needed at this power level, they will create lag. The cam gears are a good idea though.

      @Murray_Calavera yeah, I guessed as much, cooler temps, more boost, less knock, more timing, hello power. Unfortunately not quite within reach ATM, could upgrade my whole fuel system to support but still wouldn't have E85 to run it 😂  Anyway, I changed cams again, 260/260 poncam B and everything else the same except an EBC upgrade. Now I must say I was quite disappointed with the result as it was like running stock cams (didn't try to dial them in as they're supposed to be optimum already) but after awhile I suspected my new EBC was underperforming not to mention difficult to use. I recently swapped back my old EBC and it drives much better now, boost comes on sooner, more stable, no spikes etc, feels all quicker and faster than with stock cams. Planning to fiddle with the cam gears and see what happens but maybe skip the Dyno as I intend to revert to the HKS cams cos they really made the car come alive; low and mid end was unbelievable and it just wanted to rev to the moon, finally knew what people were raving about, RB26 really loves revs. Anyway, Dyno 03 is quite disappointing, in Dyno 02 although peak power was less and trailed off at the top, the low and mid end improvement more than made up for it.

      @Darrel It's so tempting to say e85 is borderline magic. It cools the intake charge, so if you're flirting with the edge of the turbos compressor map it helps dramatically cool down the hot air the turbos are pumping. It is very resistant to detonation so you can crank the timing, I don't really want to say you won't be knock limited anymore.... but you probably wont be knock limited anymore lol. I wouldn't be surprised if you made 20% more power swapping to e85 (provided you have the fuel system to support them, bigger injectors maybe bigger pump etc).
