Unfortunately the motor in my 33 is worn out after a good 4 years of ownership with most of it at 400rwhp.

I've been quoted $5.5k to rebuild to factory spec with upgraded oil pump gears. 

Would I be better to swap a Barra engine in? I can pickup a fg xr6t motor, 6 speed gearbox and ecu for $5k with 40,xxxkm on it. 

Neos are upwards of $4.5k. 

What should I do? I can see the Barra conversion being expensive.

There is a complete Neo for sale on this forum right now for ~$2.5k.

Barras are f**king enormous and heavy.  Great if you want a drag car.  Shithouse if you want a normal car that still handles.

Any rebuild should not be to factory spec.  Should be decent rods and pistons at the very least.

I have not seen a rebuilt Rb last like the factory one though. Even my tuner said once you take apart the bottom end you let the unicorn out. Rbs just can't handle abuse and barras around here are cheap and easily available. 

The neo I'd have to get shipped but that is a good price. 

Also barras weigh 250kg with everything on, Rb25 is 210kg with everything on. 40kg surely can't make that much difference? 

I'm sort of talking myself into the Barra conversion, only thing putting me off is car wouldn't be street legal..

Tell your idiot tuner to take his Bum Beanie off and learn his job properly, why the hell would you even listen to such bullshit.

Then they just aren't doing it right, the world is full of useless badly trained brain dead grease monkeys.

ah.....the "P" word.  Useless imbiciles.  I stopped considering them as an option in the 1980s.

Because the factory rbs seem to be able to last and take a fair bit of abuse. But then you can have a guy who has a forged Rb and the bearings last one event.

Because a gumby put it together. The factory isn't magical. It just knows what it is doing.

      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
