Hey all,

The time has come to sell my favourite motor, I love it to bits but its time to move on (getting into drifting, have an RB25DET lined up).

The good;

Rebuilt RB30e bottom end with RB25DE pistons and RB25DET oil pump (ACL rings and bearings, about 50,000km old).

Head is R33 RB25DET with VCT adapted running 255/8.3 surecam reground cams and Greddy adjustable exhaust cam gear.

Intake manifold is factory RB25DET with twin 60mm throttle bodies

Exhaust headers are stainless Fujitsubo Jasma large primary for RB25DE (roughly matched for peak power of current motor)

Flywheel is Billet Lightweight and clutch is VLT standard.

The Bad;

Engine is sad, something wrong in the top end (I think perhaps bent valve) blows a little bit of blue smoke on rev down and has a bit of a rattle

Also engine loves to rev and used to run an RB26DETT oil pump but cracked it (RB30e harmonics) I would recommend fitting a billet crank collar while engine is out.

Also clutch does struggle with the power (slips on gear change) would be wise to upgrade while engine is out.

This is ideal for someone keen to build one for themselves (save a fair bit of money), the bottom end is fine just needs a bit of work on the head, quoted $500 for a couple new valves, new stem seals fitted (which I can include) and a machine. As all the hard work is done (head modifications, new tensioner location etc).

Engine made 151kW at 6000rpm (peak torque at 5000rpm) with 2.25" press bent exhaust and stock headers on factor RB25DEt ECU and Injectors. Fitted 3" mandrel system and Fujitsubo headers (Which have 3" outlet) and it picked up heaps of top end, never had it back on the dyno but ran a 14.28 1/4 mile in a 1400kg+ car (R31 Ti) on factory street rims (15" & 205s).

If you were to put aftermarket management on this (haltec/microtec) and just run the TB's open (though it down include y) intake pipe the response would be great and there would be a pretty decent power increase (from tune) imo.

Price might seem high or low, I don’t know what its worth but splitting just head headers/cams/intake/flywheel I could get make more than that (but don’t particularly want to wreck the motor, otherwise I might fix head and decomp it then turbo but would be a shame).

Happy to post at buyer expense.

    • So for the wide band is a Bosch 4.9 correct for the Link G4+ along with a Can bus? Just get the Link gear or is generic ok too? Eg here: LINK LINK DIGITAL WIDEBAND CAN MODULE WITH BOSCH 4.9 SENSOR : KYP Performance House  
    • Bit difficult to follow. Have a look below and see what the standard R32 layout was like. Note there was a restrictor in place immediately before "turbocharged pressure control solenoid" that, if removed, magically got you 1 bar boost.
    • I might be way off the mark here.. there must be a T junction under the manifold. That takes manifold pressure through a check valve prior to the T, one side splits out to this bleed off orifice, the other straight to the wastegate actuators. 
    • Carrying out some engine due diligence before my first drive in a 260RS that has been in storage for 10+ years, and found two lines that are susposed to be plumbed into the boost control solenoid. One of the lines (the wastegate boost supply line) to actuate the gates, had a bolt in one end blocking it. The other line (main boost signal line) from the very rear of the intake manifold (RB26DETT) and runs up to the boost controller had this pill in the end of it as seen in photos. Other than the obvious (T28 Ceramic turbos might well be cooked)  Can anyone shed any light on if there is any validity at all with this mod, bleeding a constant fixed rate of manifold boost pressure off through this 3mm hole?  Is it deliberate?  Was this a 90s Jap mod done to RB26's? Or has someone just fitted this without any idea of what happens to ceramic T28s if they are not gate controlled?
