Hey guys,

I've searched and searched but can't find any information that tells me exactly what I need to know.

Harmonic balancer on my car has come loose over time therefore destroying the keyway on the crank snout.

As opposed to me ripping engine out and fixing that particular problem, I may as well give her a freshen up while she's out.

I don't want anything wild, a standard rebuild would be perfect for me as my car is daily driven. Eventually down the track I see myself possibly fitting a hi-flow, ecu etc. No wild power though. Id just like that peace of mind knowing that I have an as new motor.

Wreckers quote me 2.5 to 3k in and out for a replacement, im guessing for maybe 1 or 2k more I may as well rebuild my motor and know its new.

I can't get one straight opinion on who to see in Victoria, prices, whats involved etc.

So I ask the guru's here, what am I looking at price wise for a standard rebuild on an RB25DET, drive in drive out.

I ask you guys because I would like opinions on trusted workshops that you would recommend I do this. Do it once, do it proper.

Sorry for the long post but I want as much info as I can get. Read too many horror stories about people getting engines rebuild only to blow up on them 10k later!

Thanks,

Evan

To start with you will need to source a new crank. The one you have cannot/should not be repaired. If anyone tells you otherwise, then you can automatically slot yourself into the engine failure bracket with the rest of them.

Basically a straight rebuild as a freshen up will cost you about $5k but it really depends on what you are doing. Rings and bearings can just be thrown in without too much cost but to do a thorough freshen up, there is a fair bit more to it.

Ye the new crank cost is going to be the killer part out of all of it really.

Stock (or just replacement pistons) are cheap etc. It'll be mainly eaten up in labour & machining costs along with the crank.

Prices will vary but be expecting around the 5k marker as stated.

A 2nd hand motor could be sourced and installed for half that - So you really have to ask yourself how long you are going to keep the car.

Inside of 5 years, IMO forget it.

Buy a 2nd hand motor. Sell the RB25 head/parts and overall the replacement has cost you 2k.

some very good information there guys, thanks a lot. Takahashi - they are not far from where I live, have definently heard of them and their good rep. Might pay to just give them a call and ask I suppose.

Nismoid - Your idea is good too, my only problem with it is being able to test the engine before buying it, especially if it's out of the vehicle, can it still be comp. tested?

Without a crank - 4k give/take. With a crank 5k give/take.

Thats in/out and assembly costs. Either way soon as you include a crank its double the cost of a replacement 2nd hand motor... 2x over infact.

So logically speaking even if the first motor is a dud - you would still almost be infront getting a 2nd - 2nd/hand motor.

creatd is too slow. i have been waiting 18 months for them to finish my engine

18months?? wtf are they doing crafting the block by hand???

so 5k in/out...

what about if you stripped all the accessories off and took them in a long motor?

      S1 rb25/s14 starting problem

      When you crank your car, and hit it with a timing light, can you see a steady crank timing?

      Oh, forgot to add, A few months ago I was getting mixture codes and the car was using crap loads of fuel. You could smell the unburned fuel in the exhaust, it was crazy strong. Economy was over 17.5 l/100 and usually around 19. I smoked the engine and found a leaky CCV hose which I replaced and then I replaced my two pre cat O2 sensors, I also replaced the MAF. This fixed my mixture codes and improved my exonomy but I'm still 14 - 15 l/100 when pottering about town so something is still amiss. Throttle response is much better and it has more pep but I'd like to know why it's still so thirsty (and I'm hoping that whatever it is gives me a bit more poke).

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      Hello all, currently finishing up a rb25 swap into my s14. Having issues with starting, car has spark (confirmed by pulling a plug and watching it spark), has fuel(confirmed by checking pulse/voltage at injectors all spark plugs are soaked in fuel). Car cranks over and pops into the exhaust with a heavy fuel smell but no attempt to start or run, I have torn the timing cover off and triple confirmed timing, turned the CAS in multiple spots both directions, attempted to start with coolant temp and maf unplugged, checked my fuel lines and made sure they weren’t backwards, checked voltage at cas/injectors/coilpacks, made sure all the grounds in the harness are connected and added a few grounding straps (1 from chassis to block, 1 from chassis to head, and 1 from chassis to igniter chip) I am getting stumped here. As a last ditch effort I made a full grounding harness tonight that’s going to run from the battery and add an extra ground from the battery onto the coil pack harness/igniter chip/ intake manifold/ Wiring specialties harness ground/ and alternator. I’m hoping maybe the grounding harness will fix it here but posting here to see if anyone has any other ideas on what else I can check. My fuel pressure is unknown right gauge will be here tomorrow.  IMG_3206.mov

      yeah I was shocked when I checked my spare OEM on and as below that's how they come from Nissan. (side interesting note new NEO gearbox and replacement park lack the brass bush on the tips and its just all alloy) unsure about damage to the box currently back at 1110 to be pulled down/inspected and selector fork replaced as he built it previously and given the never before seen failure on his billet forks he is replacing it under warranty. He said he has used always OEM the keyway tab without issue for years so it could be an unlucky coincidence. I did talk to him about the sharp corners and stress concentration too. Re: hard shifts i got 7+ years out of the OEM one and the fork itself failed not the keyway. so could be bad luck as I said or an age thing + heat cycles in box and during fabrication of billet?
