RB30DE WITH RB25 5 SPEED

I built this engine in Jan 2004 . RB30E bottom end withRB25DE pistons which gives 10.5 - 1 compression . RB30E extractors modified with new port matched flange plate and 1 x secondary pipe lengthened to suit . It bolts to a standard bolt pattern cat converter .

Serires 1 RB25DE head . V.V.T. connected via oil pressure feed teed from oil pressure sender .

Cams have been reground by Surecam in Sydney 255degrees duration with 8.2 mm lift .

I built the twin throttle body manifold and has RB25DE throttle bodies fitted and 1 x RB25DE air flow meter . The A.F.M. is controlled by an Apexi SAFC 2

Malpassi fuel pressure regulator fitted with50 mm gauge .

RB25DET injectors 370 cc

RB25DE 5 speed gearbox . Steel billet flywheel from the Rodshop in Vic . RB30E turbo clutch and pressure plate and starter motor . Scattershield of 1/4" steel plate around clutch flywheel area .

This is a well sorted combination that idles smoothly at 700 rpm , lots of torque and returns great fuel economy . The oil has been changed every 5000 km and only used Shell synthetic oil ( $ 60 - 5 ltrs )

Comes complete with wiring harness , RB25DE ECU and Apexi SAFC 2 . Also included is a workshop manual for the RB twin cam engines ( cost me about $ 250 ).

I had this setup in my r31 station wagon .

PERFORMANCE

1/4 mile 14.15 @ 97.6 mph 16/8/2006

Max speed 141.18 mph ( 227.2 kmh ) average speed over a timed mile at Lake Gairdner speed trials March 2006 .

In Brisbane and can ship interstate at buyers expense .

If your drivers license restricts you from having a turbo powered car , this could be the engine for you . As you can see by the perfomance figures it would leave a stock rb25det behind ( dont know about neo engines).

Best to phone me on 0413 546380

$3500

as written on r31 skyline club, VERY interested!

Whats been done to the bottom end?

also, are you using the factory RB30e fuel pump?

That is pretty much the EXZACT engine ive been planning on building, its perfect...

Bottom end . I put in new big end bearings , rb25de pistons with new rings , replaced all gaskets and seals . Steel billet flywheel .

I used a Bosch 040 in tank fuel pump .

      R32 Nostalgia

      From my youth: GTi-R clutch change is a massive pain. The gearboxes are fragile? But the car is super cool and I want one 😢

      Driveline vibration is resolved. I ended up loosening all my engine mount and trans mount bolts, giving it a good shake then retightening everything and it's gone... Let's just say I was surprised that fixed it.  I've been happily driving it around again but unfortunately put zero time into my direct port/constant pressure WMI setup. I'm on vacation next week, so I'll try and finalize it then.  On a different note, I spent all week fuel/ignition mapping 2x 216L V16 engines. Turbo's were burning glycol and we swapped them out for larger units. We also had planned emissions testing on site, so I figured I'd be there the same week to use their instrumentation and massage any emissions issues out if needed. This was a first for me. Fuel management is similar in certain ways to automotive (i.e air density as load variable) but very different in others. It's all PLC based and AFR's are controlled by air and not fuel. They use a control valve between the turbo and air manifold to control pressure which in turn controls AFR's. Due to this, target AFR tables supplied by the OEM are in pressures and not mass which really through me off. They use air pressure vs fuel pressure tables. I also relied on an O2 concentration sensor the emissions team had in the exhaust. Ignition timing was also all over the place and we were losing a fair bit of power. They're now happily sitting at 16-40BTDC depending on load. We were making about 1600kw at 900rpm at 90% load. Engines were running a lot smoother as well.

      Oil pan for RB25DET NEO Stagea "version"

      By Duncan · Posted

      meh, it was a good video, clear about the issue and how he dealt with it. A bit heavy on the RTV and very brave to put an RB in anything without rebuilding it first, but otherwise I thought it was good Dose, I'm not sure that having the pickup forward is a big issue; yes of course the oil could shift under brakes but the sump should never be empty enough for that to be a problem (unless you also have a higher volume oil pump, and that oil can't return from the head to the sump quickly enough)
