Hi Guys

I've been thinking about building a RB26dett and putting it into my 33, although i have a few questions regarding it.

1.Since ill be keeping it RWD would my current RB25det box bolt up to the 26dett without an adapter plate? also would the tailshaft need to be a different length?

2.Could i place a R32 RB26 in a R33? or would it be best to keep to the same model (r33) so the loom is quite similar?

3.Am i looking at a good power differance compared to the 25?

4.Will it drop straight in? (engine mounts different?)

I did try and search but i couldnt seem to find what i needed answered.

hopefully someone has done this and kept it RWD,

Thanks for the help guys/gals

Richard

There is a bloke in Townsville that has done this conversion.... You can find him on Qld street scene (www.queenslandstreetscene.com) and his user name is RB25_forever.

He'll be more than happy to answer any questions that you have :)

Ask Marty what it ended up costing him aswell lol. I don't see the cost benefit. The amount of money that conversion cost him could have had a fully built RB30/26 or RB30/25 with what ever turbo selection you wanted, instead of a 220rwkw stock internal RB26 that ended up letting go.

It all comes down to what work you could do yourself, if you could do everything yourself (engine out, engine in, wiring new loom etc) than it wouldn't be too bad.

Just the cost of the engine, ECU, sump modifications, wiring harness, exhaust modifications, intercooler piping, mod plate etc. I would do the clutch, engine mounts, fuel pump and a couple of other things while i was at it.

It all adds up. All the little things that you don't think of start costing a bit. Trust me on that one.

i have done a 26 conversion to my 32, it might help with ya 33

i guess you know you will have to get the 26 sump modified for rwd

you might have to change ya engine mounts on the 26 with ya GTS-t ones

with wiring you will prob have to wire in a resistor pack for the injectors thats with the 26 wiring loom

you will get around the 300wrhp+ on a stock 26

Anyone have any specifics? I have a 26 with loom im trying to power up. As i don't have the factory body loom i need a bit of info

I'm just trying to power up everything properly.. do i just run positive to the 2 relays near ecu or do i run it to the plug on the driver strut tower?

Is it an R33 RB26 loom you are using? Do you have a series 1 or 2 R33?

Ive got an r32 loom going into a race car with no loom whatsoever. Ive so far sorted out the power feed for the resistor pack and found the injector feeds in one of the big plugs on what i assume is the passenger guard part of the loom near the afms.

I'm sure you must be able to just run one or two power feeds to the loom somewhere on these plugs but i can't trace where. not having seen the original car makes things a bit tricky.

      I have more than enough digging, laying blocks, moving gravel, airrating, feeding and top soiling the grass, and setting up the veggie gardens growing some seedlings,  and then removing all the unused rock to keep me busy for the next few months at least,  hopefully the rain stops soon so I can get a few hours in this arvo, but, before that Sunday is washing day, is every body happy, you bet your life we are Nice country road day drives are a day off whenever I'm muscle sore from all the landscaping at the moment, but, more epic multiple day drives will start once the majority of the big jobs outside are completed

      Recommendation for engine oil funnel spill free

      By MBS206 · Posted

      I thought I'd come back and add something I JUST learned. A Toyota LandCruiser with a 1HZ, mates perfectly with a bottle of Nulon brake fluid. As in, it perfectly screws in. Great make shift funnel when you cut the bottom of it off. This may work for your Corolla.   Unfortunately, tipping a 10L drum is much harder than a 4 to 6L bottle, and they no longer include the easy pour tap which was just perfection to use previously.

      Fuel Pump Control Module & Dropping Resistor

      By EndZee · Posted

      Guys since i bought r33 gts25t coupe 1994 automatic a/t(manual swap 350z gearbox)  all i got is problems, always problems. Lets start with that when i turn key into ignition(ON) fuel pump doesnt always works. Sometimes i have to turn key twice Off/on/off/on until it primes. Its new, dw300 - 340lph. My gearbox broke so i did gearbox swap, install different intake manifold, injectors and i take pipes. Car was sitting in garage for more than half a year. I did assembly all not that long ago and when i turn ignition cant hear prime. All of sudden it stopped working. Theres many videos on YouTube how to make relay mod on r33 straight from battery so i did and it doesnt work! 😰 30 - battery positive  87 - positive from fuel pump to relay 85, 86 - one of two wires from original fuel pump wires(light blue, grey) and it didn’t work. so I check on ignition and took original BLUE relays wires from trunk, next to fuses. (I believe it’s IGN+ and ECU pin 18. it didn’t work…  tried connecting (IGN+ from og relay) and (ECU 104 from 1of4 FPCM wires) to my new relay 85/86 and it didn’t work.  I unplug FPCM. Didn’t work. im thinking what’s wrong   fuel pump is working, if I leave IGN+ on 85 and 86 straight to ground it works but it’s just nonstop. Since it getting constant 12v after key in ON. light blue wire gives me 6-8v.  so how this should be connected? What causing ECU not giving — on pin? Or I did sth wrong and that’s why it doesn’t work? I need negative signal on ECU that control fuel pump. What this should be?

      M35 Brake caliper replacement

      By Duncan · Posted

      You can use your VIN to look up the factory part number somewhere like amayama, and then look to order new if necessary. https://www.amayama.com/en/genuine-catalogs/nissan Depending on price you might want to rebuild instead. @GTSBoy I had an interesting insight into US market parts when the Titan rear calipers were sticking. New calipers were dirt cheap, about 20% more than a rebuild kit....they are just considered throw away maintenance items
