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

was going to post exactly this. its the little bits that blow it out. few hundred on this, few hundred on that.. maybe replace this and that while im here.

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 :(

    • This is the territory of the "Stage 1/2/3 Golf GTI/R" or otherwise off the shelf tune with (relative to before) minor mods. It's easier now. Downpipe and Tune and boom, big increases. Stage 1 OEM+ is where it's at. This is where the niche evolved into and it's really easy to see why. It's rare to even NEED to consider changing turbos or going to aftermarket ECU's or building bottom ends for more power. Stage 1-2-3 will get you a LONG WAY. Civic Type R turbo GR Yaris/Corolla Anything with B58 (MKV Supra/x40i) Anything BMW in General Anything Audi in General Any turbo AMG RenaultSport Turbo offerings Korean Elantra N/I30N Ecoboost Mustangs Focus RS? List goes on. I would argue in the future it won't even need to go on... M3P is pretty rapid out of the box...
    • There is a way, but it's not with the same cars. You need to find the same vintage of car, that we had. Realistically, that was an affordable car with aftermarket parts around. So what people need to find is a car that had a decent base in its day, and can be modified. They're looking for a car year make of 2010 to 2015 really... Aus could have done it if Holden didn't fold as V8 commodores were cheap, and if Ford didn't get expensive thanks to COVID, then you could cheaply play with FG Barras. Realistically, those are just a bit heavier, four door skylines. I'm sure the US and UK have similar cars they could find.
    • Haha I do that.. thats when it chirps..The bit point for me is almost non-existent. Otherwise I stall it. But yes, in terms of performance, the clutch is solid af.
    • Greg speaks wisdom. These dirty old Datsuns are only value when they are cheap. When they are not cheap, there is no value. Sounds contradictory, but it's true. We are now 20 years past the hey day of modifying cheap 90s JDM cars for small amounts of money. This is a different world. If you are rich and can afford not to care about what is effectively wasting money on an old Datto shitter, then I have no reason to argue against it. But if you are wanting to experience what we all experienced back in 2005 (and I bought my car last century!) then there is no way to do it.
    • Short answer: No. Medium answer: No, because you still need to conjure the things out of thin air to bolt them to a NA to make it a NA+T. Long Answer: No - The things you need to conjure - meaning a turbo, intercooling, manifolds, exhaust, intake/manifold/piping, clutch, injectors, fuel pump, AFM (?), ECU + Wiring (woo, N/A loom fun) have to come from somewhere. You could have many scavenged these things from an OEM car that someone had upgraded from and use some of these. This will be cost prohibitive now, especially so in the USA. You'd probably pay the same for newer, upgraded components that are better than old OEM stuff from 25-30 years ago. None of these big ticket items are re-usable for the N/A car. Why not buy new and upgrade while you're there? The only real consideration is turbo and fuel sizing and determining whether you want to stay within the bounds of the OEM engine or get into rebuild territory. These limits ARE lower with a N/A motor and especially N/A gearbox at the starting point. And if you're gonna upgrade those then you may as well consider having them built to begin with. Because everyone here knows you're never far from that next engine rebuild once you start making the power you want... The cars you see on the internet and SAU etc have been built over decades. If you're really clued in... you would sell your US car to somebody for what you paid for it. You would then scour AU JDM pages or SAU and buy a car like Dose's on this forum with your powerful American Dollar. This will save you so much money in the long term. Importing it could be tricky. Or it might not because USA. I have long said the only reason 90's Japanese stuff took off was because a) Japanese people had Japanese cars so that is what they used b) Australians could import these cars to Australia with very minimal changes and use them on the road here c) Neither country had well-priced access to US or EU Sports Cars. I don't believe the JDM scene would have taken off in Australia at all if we had EU priced EU BMW M offerings, or more especially the AUS V8 Scene would never have existed if we had the multitude of US cars like Camaros, Mustangs, Corvettes at the prices you folks do. After all - Do the math. I would say put a V8 in your R34 and that's the smart way forward. It is. I did it. I know this from my own experience. But at that point there's no reason to simply not buy a C5 or C6? It would be simpler and easier and cheaper and bette-
