There's a handful of different reasons ranging from heavy clutch kicking, revving too high, poor assembly of the engine when it was rebuilt, damaged crank prior to rebuilding but wasn't picked up before it was assembled......and the list goes on

I'd need to see every single piece in detail to be able to tell you exactly how it failed.

I know the old owner and heard story's that he loved to reclutch it everywhere.. Also the high revving he use to do as well, I believe the crank that was in it was in good form and it good balanced and all

No, but it will have been damaged by the same f**k-knuckle driving as damaged the motor.

speaking of engine damage, does a few bounces off the limiter cause any of the above issues, i set my limit to 6000rpm but when the tyres loose grip its bit hard to stop it bouncing off it, id imagine in the drift and drag area they'd be doing this all the time..

My limiter is set 300 higher than I plan to take it just so I never hit it

Yeah, that is the heart and soul of the problem and one of the solutions. Limiter bashing is very bad. Occasional limiter clipping is probably OK, but Murphy's law dictates that you will break an oil pump drive even on an occasional limiter bump. If the engine won't self destruct by running at faster revs than some notional rev limit, then it is better to let it just rev up over that notional rev limit occasionally, rather than hit an electronic rev limit possibly more frequently.

thanks for the info, will raise it back up and be careful then

cheers

Can also retard timing tapering back from your desired limit a few hundred revs.. Ill be getting this done on my next tune. that way you lose lots of power before limiter so you wont be going near it deliberately. And it softens the limit somewhat I believe. i.e. my limit is 7700 atm, start retarding at that to a 8000 limiter..

Has anyone got feedback on this idea?

And back on topic, how much kicking has one got to do to abliterate a thrust bearing!?!?

Haha yep f**ked on a hole

New level,

Not using anything off that motor apart from the head and cams

Started all over, bought a block girdle and crack, rods bearings main studs, motor should be finished been built this weekend

That is shockingly bad. Whatever the problem the owner would have known this engine was seriously broken LONG before he took his foot off the loud pedal.

Go out and buy a stock RB25, go from there. You can keep some ancillaries from this engine as spare.

Personally I'd take it to a different engine builder.

Hahaha funny thing is, when the owner was trying to sell it he was saying the day after it bogged down and it got hot he started it up and there was no knocks or anything... BULLSHIT lol thing would of been knocking its head off,

I got the car pretty cheap knowing something big or small could be stuffed didn't think this much damage would of been done in 2000ks tho

Yes I have started again with a NEW bottom end and the motor is been built by a different person (not the person that built it the first time)

Wow man, I just had a read thru this thread....

What a heartache, half of me feels sorry for you...

The other half says 'serves you right' for NOT test driving a car before purchase! Mate, that is such amatuare mistake to make. Sounds like you got caught up in the moment, the word 'skyline' tends to blind ppl to the obvious sometimes. Hopefully this whole experience opened your eyes a bit and has made you more cautious about buying things without inspection in the future.

What I am interested in tho is,

What was the total cost to get it runing again at the end of the day? (includes original purchase price, parts and labor)

Cause from what I have seen, it sounds like it could of cost a fortune.

Lol first of all mate, I bought the car off a mate, already knowing something was wrong with it, etc (head was already removed from car) no one new what could be wrong with it and on purchase I knew it could turn out to be a f**ked bottom end, and it doesn't bother me as I paid for the car at a low price (what some people would pay for rego and insurance)

I only had to build the bottom end, but I've also gone with nitto rods nitto oil pump ho volume sump new garret gt3540 new plenum new throttle body

Just seems like a hell of a lot of trouble to go thru to get a working/running Skyline.

There are 33 out there (running) for like $5K. I was just interested as to why you've chose the 'hard road' so to speak?

Might just be me, but anyone that sells you a lemon is no 'mate'... Unless he didn't want to sell it to you because of the issues with it, but you insisted, in that case he is quilt free.

Everybody's logic is different, but I just don't see the sense in buying a wreck? I could maybe also understand if you had always wanted a skyline but didn't have enough cash and then this popped up at the right price, so u grabbed it.

I'd still love to know the total cost of this exercise $$$? But if you don't want to say, I will respect that.

Either way, best of luck with it. Hope it works out.

Could have a running car for $5k but it wouldn't be anywhere near what his car is going to be and sounds as though he paid that little that if he wanted he could get a stock rb25 motor drop it in and still have done well

    • My experience with Rising Sun Exports Before agreeing to the sale I tried to do as much research as I could (obviously), his Facebook reviews are 98% and he goes Live at least once or twice a week. I contacted 2 people in the UK who had used him for their imports, both had positive feedback. His explanation and talk through of the import process was thorough, answering any query no matter how stupid it was. It felt as soon as the money was sent, communication dropped off. I asked for shipping updates every 2 weeks or so, not wanting to pester him, he never had any updates. I wasn't informed the car had been dropped off at the port, I only found out by his Facebook story. I asked for the photos taken at the port, knowing he would need some for insurance purposes. I received a few 5 second clips and that's it. When asked again, he said his staff had them. Weeks later I asked again, he tells me he doesn't have any, but does have 50 photos from the original advert. I never received them. I eventually got the documents sent via WhatsApp after I mentioned the port was requesting them. I purchased a CarVX report, to find out the vehicle is a Grade R with recorded accident damage, first recorded in 2017 when it was first auctioned. He never told me the grade, then again I didn't ask. His response was "Grade R means nothing, it wasn't chassis damage". Still, I would have liked to have been informed about it. Jon prides himself on being open and honest when it comes to inspecting cars, it's his main job doing so at the auctions for customers. When the vehicle arrived in the UK I noticed a few little cosmetic issues. It's a 21 year old car so it wasn't going to be mint condition. The side skirts are cracked on each corner and the sealant is failing. The front grill on the bonnet/hood isn't secured very well, mounting studs are missing. Both minor things, but again, it would have been nice to be told. During a Facebook Live walk around video of the vehicle, he mentioned it has a front Whiteline anti roll bar/sway bar. While on the inspection ramp, I noticed the stock item has been installed. When first questioned, his response was "the ARB? Switched? Since when, it never had them". Since sending video and photo evidence I've not received a response. I'm probably being over critical of the overall condition of an old car, but all I wanted was honesty (which he claims to have). I'm aware I wasn't his only customer, he's busy doing XYZ but other reviews praise him for great communication with regular updates and photos, I felt I didn't receive the same treatment. 
    • I was able to get some underside photos while the car was on the ramp The suspension is all Altezza/IS200/IS300 so getting part's will hopefully be less of a headache
    • Welcome to my 2004 Toyota Mark ii IR-V Fortuna (series 2) With a 1JZ-GTE powerplant under the bonnet (hood) it'll give me plenty of scope for power upgrades. For those who aren't familiar with imports, the 1JZ-GTE is a 2.5L 6 cylinder VVTi engine with a single turbocharger. This has the factory R154 5 speed gearbox, along with a aftermarket 2 way LSD differential (brand unknown). Under the arches are a set of CST Zero 1 alloys, 18x9 +30 225/40 up front and 18x9.5 +15 265/35 on the rear. The car was quite low in Japan and there's evidence of the wheels catching the rolled arches/fenders. The tyre's aren't great so I'm in two minds whether to replace both or just the tyres and put up with the wider wheels on the rear. The car still uses stock brakes with the addition of some braided hoses. The exterior is stock with the exception of a BN Sports front bumper and a replacement Fortuna grill  Moving to the interior, the steering wheel has been replaced with a dished MOMO steering wheel (which will get swapped for my Momo Tuner for the time being) Defi Link Gauges are mounted above the climate controls and on the A pillar, the Oil Temp,Oil Pressure,Water Temp and Boost gauges should help with spirited and track driving  The stock seats have been replaced with some retrimmed Recaro bucket seats. Being a larger build these are a little snug, unfortunately the orange isn't for me so I'll look into replacing these down the line. Other modifications include a twin plate clutch, Blitz intercooler, Evolve alloy radiator, a stainless exhaust with decat, HKS EVC-S boost controller and coil overs
    • Apologies for the long read My R34 GTT was up for sale at the beginning of spring due to a few repairs creeping up. The strut tops needed replacing, roof and bonnet (hood) painting (yay for 3 stage pearl) and the underside stripped and treated. I sold the car which allowed me to be in a much better place financially. Leading up to the sale I was already thinking about the replacement. In an ideal world it needed to be a good all-rounder. Something I can mess around with, modify, do track days, do the school run, go on long drives etc.  Options included but not limited to... Laurel C35, Evo 8/9, Civic FD2, Impreza Hawkeye, Aristo and even an Audi S4 Avant (I've already got the Mazda 6 wagon). But there was always one car at the top of the list The Toyota Mark ii JZX110 I found an advert on a Facebook group for an example in Japan, from a seller called Jon at Rising Sun Exports. A few messages back and forth and Jon calls me from Yokohama one morning (or afternoon in his case). He briefly explained the import process, the costs involved and a repeat of the advert. After much deliberation, the price was agreed and the sale was locked in. I've never imported a vehicle so I jumped into the unknown head first. The money transfer was completed through wise.com (fees apply), very easy to use and the money was with him within a day or two.  The car suspension was raised for the vessel and the car dropped off at the port. It was 7 weeks later when the bill of lading was received and the freight invoice sent to me, followed by the export certificate a couple of days after (both digital copies) In the mean time the port had been in contact. I needed an agent to deal with the NOVA (notification of vehicle arrival) along with the tax/duty invoice, this was £75.00. The port also had a fee of £100, I'm guessing to cover the cost of the 10 day 'free storage' and for moving the car off the boat etc. They need a copy of the vehicle invoice, freight invoice and export certificate to allow the vehicle to pass through customs. The vessel arrived on Tuesday 5th August, the tax/duty invoice was generated and sent over. This is generally tax 20% and duty 10% of the vehicle value. Although the invoice came in at a higher amount than I had calculated. Once HMRC had received the payment the vehicle could be released from customs. I thought once the tax/duty was paid you could collect at any point, that's not the case. Your agent will need to book a collection slot, I requested Thursday 7th which was accepted, with a 9:00am slot allocated. It was a 5:00am start from Norfolk heading to Southampton. We eventually found the compound, upon presenting the bill of lading and some ID they released the car (they drove it out of the compound to the front ready for us to load up). The email from the port stated each slot had a 10 minute window, which seemed abit farfetched but the staff said it's not a strict rule. We were there for approx. 30-40 mins in total. A week prior to collecting I contacted my garage and explained the situation, I was able to get an inspection slot that afternoon. For the registration, DVLA require the car to be insured, for this I used a company called Adrian Flux who can insure the vehicle using the VIN number. 
    • Hey guys, looking for these side skirts if anyone can help me out.
