Hey guys,

 

Wondering if any of you that have built or had built an RB short block would mind posting your estimated build cost.

 

I am in the process of getting quotes and they range from 5k to 15k

 

This is short block only.

 

Peak rpm 8000

Power 700hp

 

Professional job with quality parts.

 

Any input is appreciated.

 

Don't mind the look of the spool short block on their website at $6600 thoughts?

This is only an approximation based on mine.  There would be a lot higher examples and possibly a bit lower but you'd get a pretty good engine for that.

$1500 pistons

$1000 rods

$500 bearings

$1000 Machining

$1000 Labour

$15k looks a bit OTT

Ewan's $5k is more like it...although you might want to fully balance the lot.

For NZ$8K Rips wil biuld you a fully forged 2wd RB30 short block  or for $13K a complete engine.

Everyone forget all the little things that add up, oil pump, studs, gaskets, new factory oil cooler, hoses, drilling out oil returns, Welch plugs and the list goes on 

+1 for this. Also depending on what engine it is. If rb26 I would b adding in an extended sump so that's another 1500+ and while the motor is out I would also be doing the front diff

With no labour for assembly as I'm a mech my long motor cost me 11k 

That's spool I beams, cp pistons, spline driven oil gears, new oil pump for the housing, new water pump, new timing belt kit, seals and gaskets, cometic head gasket. Arp mains, arp head bolts,new valve Springs, exhaust head porting, head reco, block decked, bored, tunnel bored and chemical clean, crank linished and collar fitted, random fittings for external oil feed for vct, sump modifications, a few other bits and peices

Yep to the pins and fasteners yet no the rb26 bearings. My motor currently only making 335awkw on e85, yet will go alot higher once I have more funding to upgrade the turbo and manifold as its currently just the stock rb25 manifold with an internal gate hypergear atr43g3

Yeah this bit. Wish that I had this done but when the unexpectedly high (to me at the time at least) engine rebuild costs mount up it is so hard to justify.

If you're gonna rebuild... build a stroker! It's so little.. for so much more!

If staying 2.6, put another stock engine into it....

HUH? If ou need a new crank then perhaps....but if your crank is healthy than 2k on rods and pistons...whats the cheapest stroker kit these days?

Why would you leave the factory throw crank in there when for a little bit more you could have a stroker?

You're paying for machining, assembly, studs, gaskets, pumps and consumables anyway.

Baffles me why guys go to all that effort and leave it standard capacity.

LOL Price? They all seem 6k. For me thats another 6-9 months of saving over an ebay piston/rod deal for 2k:( Baffles me that peple have the disposable income to shell out on stuff...by baffle i mean envious. I am still trying to piece my car back together after 2 years of being off the road and tired of being broke and spending all my spare cash on cars :(

      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?
