Hey guys,

I've just bought an R31 coupe in japan and was wondering what you guys think i'll be looking at power-wise from the engine thats in her.

RB24DET (rb26 crank, rods and tomei pistons)

KKK K27 turbo

Trust high mount manifold and external gate

rb26 plenum and injectors

rb26 cooler

HKS FCON V

HKS EVC

thats about all i know, its garenteed to have lots more mods as i can see alot of things in the pics i got that wern't listed.

so what do ya think? am i looking at over 200rwkw here?

Cheers

Karlos

Yea i thought it looked like a monster turbo. hmm wonder how laggy it'll be?

well non complied i'll be getting it for around 10k but then i'm gunna have to get it through compliance. i'm hoping if i chuck the standard manifolds and turbo back on the 2.4 will still pass emissions at regency. should cost a couple thousand plus to get it complied because of all the shit i have to return to standard! :(

Racing Porches and Ruf Porches run K27 in single and twin forms, so should be a dood thing. Is it a Blitz or original KKK turbo?

If everything is in order i woudl expect power to be up around 280-320rwkws depending on some of the mods, and boost it runs. Just be sure its actually has the internals before you wind up the boost too high, its way too easy to claim all sorts of things with regards to stroker cranks and pistons, so a quick inspection woudlnt go astray before you start turning up the wick and showing the R33 and GTR crowds what an RB20 can muster...any pics?

ok i'll load some pics onto my webspace.

worth buying one what? a spare car? i thought about getting a front cut but hopefully i can lease an rb20det and the rest for a week just to get through regency for considerably less than buying a FC.

280rwkw?! shit sounds like i'll be looking at a ****in quick car!

yeah i noticed the 2nd fuel rail aswell, didnt notice the single throttle, hmmm i must contemplate this new discovery..

i wonder whether thats 12 GTR injectors or 6 RB26 and 6 RB20 injectors.

also notice the remote oil filter, oil cooler?

wish these japanese were more informative, i wonder what clutch its got? whats the gearbox gunna be like when my last box broke with only 170rwkws?!

oh and this is gunna be my daily driver! :headspin:

Looking at how close the inlet manifodl sites to the inner guard/strut, it looks as though they may have cut the std RB20manifold off after the injectors and rail mounts, then either welded a flange to bolt to the RB26 plenum, or cut off the flange on the RB26 plenum and welded it to the modded RB20 plenum.

Does anyone know where the injectors on an RB26 inlet setup are bolted, im guessing its after the 6 throttle bodies? Perhaps the 2nd row of injectors are acoomodate dby welded sockets in the plenum, rather then using the STD GTR rail and mount, which actually the 2nd rail looks liek they use hose tails so may not be std GTR Injectors.... be fun to play PI when the car arrives

Hmm, wonder why they've used 12 injectors anyways? why not just go 6x GTR ones and use the entire rb26 inlet plenum/throttles? gtr injectors are large enough arnt they?

looks like i may need to change the whole motor over to get it through regency, not just swap int/ex manifolds and turbo. i doubt the 2.4 would pass emissions with all standard gear (inc ecu/loom) chucked on.

0HR30t the interior is in awsome nick, looks brand new, tons of aftermarket gauges etc too, just no stereo.

a few r32's came in with similar mods they were pretty good my suggestion is wait till it gets heere and talkto the compliance engineer first. I think the lease of a complete motor might be a better ideaor else you might upset the balance and set up of the old one) and itwill be alot easier alot easier to unbolt and bolt in.

hope for 250 rwkw and be very happy if you get more the car will be laggy even with the 2.4 kit but should rev very well and very high. enjoy

I think if lag is a problem i'll swap the turbo for something smaller, mabye a 2835r or the like. trouble is if i do that then i'll have to get the ECU retuned or change it altogether. anyone in adelaide that knows the Fcon's?

    • 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 😢 
    • Remember this is 1988 tech.
    • 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.    
    • heh, aint no R32 ever meeting modern targa cage rules unless the driver is veeeery short OP, good luck with the sale, since its already in the land of freedom I'm sure you will find a good buyer.
    • 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)
