Gonna be a major teardown of R32. Next time Oscar, it's not a good idea to laugh when a $15000 bottom end lets go mate, not everything is a joke. Engine failure is serious stuff. Let's just say you've been very fortunate with your car. Looks like nothing to do with tune, just oil supply starvation from launching at 9200 with a stock sump. This bottom end is all going in the bin probably, I'm not just gonna chuck some bearings in and "she'll be right". Fab take note and be very careful what you choose to do to repair your 26.

Just finished discussions with the old man on which path to go down - HKS 2.8, OS 3L or keep a 2.7L capacity. 3L option is too much at $29k, HKS 2.8 is tempting for 800ps stage 2 but too much for stage 3 1200ps option right now, so it'll be a 2.7L capacity again.

On order first thing tomorrow is Trust sump extension, 86.5mm CP pistons/rings, crower rods, R33 GTR crank and R34 GTR block - all brand new from Perth where machining for block and balancing of crank will be done. Trust Dog box is going back in too.

Don't worry, I'll be back stronger than ever.

How was the oil supply over looked when the engine was built to start with? I don't know much about 26's, although it'd be Russian roulette with nearly 5 times the factory power to happen reliably with the factory sump on any car. Seems like a good opportunity to see if there is anything else that could be improved.

What can I say?

I :whistling: LOVE carnage in my motorsport!!! Speedway is turning me into a sadistic prick.

There is nothing better than pushing a car or engine to its limits and beyond.

I thought that my RB would be the first in town to go pop considering the 2006 standard rebuild, standard cast pistons, 200+ HARD 1/4 passes with limiter launches, 2 burnout comp wins, wearing my 4 M/T's to the wire and peak holds of boost above 1.7 bar.

The only thing keeping it alive is the N1 oil pump, tomei oil restrictor, sump baffles, oil changes @ <100km and good luck!

On a serious note Ben call me if you want to sell your 16" wheels & M/T's $$$CASH

I reckon these with new bov's and a serious weight reduction I may be able to give the 10's a nudge.

wats up orderd a new r33 gtr crank bearings and rings ill get a new clutch as well were tearing this motor to a bare block clean evry thing make sure it dont happen again and run the bearing in proply so i can burn sum rubber at drags and get sum decent et down the strip its on ozzy wen its back on the road best burnout :):ermm:

You're right Kurt as at 7k rpm and above there is no oil left in the sump on a RB26, it's all in the head.

So $11000 and counting with the new build for the engine. Just got back from the rock, gotta pay for this new bottom end. Xspeed have machined and assembled the brand new 34 block, 33 GTR crank and 86.5mm CP pistons/rings and crower 74mm rods. All brand spankers so I'll have to run in a new engine from scratch. New kings bearings have gone in and most importantly, a TOMEI 1.5mm HEAD RESTRICTOR for the bloody oil issues. Have a Trust sump in the works too, which should cure the 9k + rpm limit. Will be boxed up on Monday so I sould see my brand new bottom end maybe next week. Still gotta pull the engine out still, which is a major mission on a GTR at nearly 400kg with transmission. I can't see this car being done for a couple of months though. HKS turbo is leaking on compressor side so that'll have to get serviced/resealed on the housing.

Oscar I'll see you some time on the weekend OK

Track is becoming a good place to hone your technique on getting the car down the track faster. New manifold is getting ordered this week. Gains from their design is said to be spooling 200-400rpm sooner and 6-15% more power. Can't wait.

Wouldn't you have already had a good manifold to mount a Trust T67 ? Was yours cracked ?

GTR engine and driveline is fully removed from blue car. Finished it about 2hours ago. New bottom end is assembled and sent. Anyone says they can remove an RB26 and transmission from a GTR in 2 - 4 hours as I've heard so much people talk shit about before I'll give em a grand to watch it happen. The GTR must be the worst car in history to work on for rebuilds, give me a RWD car anyday. The engines themselves are great though. I picked up Fabs gearbox to my chest on Friday by myself, try doing that with a GTR box and you'll be walking no more.

Trust manifold that is mounted to now would be a good design and quite nice for a more mild amount of boost. The stainless steel manifolds are quite well known to crack like mine has. So I have ordered a steam pipe manifold from Kyle at 6boost. This will ensure I will not have to replace it again as they come with a lifetime warranty against cracking or defects.

Good work on getting the motor and gearbox out.

Motor is apart totally. Whoever at Jakes performance let this engine go out like this is a bloody dropkick. Rings have bugger all tension (which would explain the engine breathing) and stock nissan main and big end bearings which have copped a hiding. Number 2 conrod bearing let go with number 3 on its way out. Conrod cap 4 and 5 were swapped around and get this, my engine mount bottom nuts were both gone ! Engine was just literally sitting in the car !

Bearing failure was not from oil supply issues at all, as they were not welded to the crank or conrod like Fabs. The car has just been absoluely hammered at a very high rpm for way too long before I bought it. Still going to address oil issues though, cause I ain't doing another rebuild on this car. Not in any hurry to get it back out drag racing, definitely be next year for the R32. I'll race the last night round in the v spec.

^^^^ sucks, but i suppose you gotta expect things like that when its someone else's project first. my car is looking more mismatched than ever....... but i think it has a nice drift pig look to it :D i might have to get out the spray can to match some panels up lol

Nothing a bit of time can't fix cam. You've been pretty patient so far so it should go pretty well.

No racing for me this weekend as my manifold hasn't arrived yet. I'll be out on the 13th if they still run that test and tune, if not then it'll be the following bracket.

I know what it's like to find engine mounts missing bolts BK, I found mine with one missing and the other only hanging on by a couple of threads. Last tome I allow someone else to work on my car. That is the main reason my manifold cracked, the twisting of the motor caused the wastegate pipe to hit the chassis rail while the engine and exhaust was a full temp causing the pipe to crack and split wide open. $1200 later I've got my problem fixed.

Who is the 26yr old Skyline driver caught hooning last weekend?

Did they have proof or was it just a phone call from the public?

I would like to see the so called 'evidence'.

    • In a few years from now, you'll regret that. It'll eat away at you, knowing the truth of the ugly hiding beneath the beautiful exterior... 😛
    • I don't think the G2 profile is particularly dangerous for the engine per se, more just are you actually ok with the turbo lag trade-offs? If the answer is yes then go for it. I personally don't think I'd be ok with it because I spend so much time at lower RPMs and I really enjoy the feeling of being able to stay in 5th gear on the highway and just roll into the throttle to get boost. Or staying in 3rd gear on "gentle canyon cruises" without feeling the turbo lag too badly. The 525 pump should be able to run flat out on factory lines but I would bet the pressure drop from pump to regulator is quite impressive. I don't know how much it would be exactly but I've seen figures like 30 psi thrown around.
    • It's interesting seeing everyone talk about what level of risk they are happy to tolerate.  Building a GTR always has a level of risk, you could be that lucky guy that drops 20k on the engine build alone and still has the thing go pop on the dyno. Life is fun like that.  The way I see it, the thing is a toy to be enjoyed. I'd be happy to turn up the power on stock motor and limit the risk with sensible tuning and engine protection. If it still goes pop, it is what it is. The car isn't a daily driver so it can happily sit while a plan is made to sort it out.  Given this thing will be a street car only, I really feel it's worth the (relatively small if managed well) risk to turn the power up to around 350KW on e85.  I don't think anyone getting into the skyline game now is doing it out of logic. Surely it is a purely emotional decision so I'm not sure how important it is to think about the engine build logically. The heart wants what it wants.  @joshuaho96 little note for Josh, I run my 525 pump flat out all the time and through the factory lines without any issues. (excluding the melting connectors, that's sorted now. we'll pretend it never happened lol)
    • But the Nexus S3 is very expensive and won't be as purpose-built for the application as a separate electronic boost controller :^) More seriously my pet issue here would be that the Walbro 525 running at 100% duty cycle is going to require more FPR than the stock setup can handle. I'm also pretty sure from what I've seen elsewhere you might want to slow down the pump regardless unless you're going to come up with some way of upsizing the fuel lines coming from the fuel tank. Factory 8mm fuel line doesn't actually flow very much if you want to keep pressure drop down between the fuel pump outlet and FPR. If you really want to "keep it simple" I would run only as much pump as you need and source a fuel pump controller to slow down the pump in the vain hope of being able to run stock-style FPRs which are pretty dinky. Or just use the HICAS lines and it should be mostly fine. OP should also really think hard about what profile they'd want out of the turbo. My pet choice here would be the G1 profile rather than anything higher power but YMMV. I already think ~stock turbo lag is pretty bad so I don't want to make it worse. In "gentle canyon cruising" I found that I spent a lot of time around 4-4.5k RPM. I also recommend DIYing labor if you're detail-oriented enough. Costs are high for labor + if you do it yourself you can be your own quality control.
    • GTSBoy is again on the money. My actual advice? Sell the car. (really). For what it's worth as is, you can sidegrade into something much better. If you care about function then this is the actual move. If you want a Skyline to perform, set aside about $100K to do it. This is NOT a typo. You will see right away these are two very different mindsets. Realistically we're talking full restomod for any Skyline still kicking around. Have an honest think about which one you are.. and what you want to do, and how much you want to invest in this (with no return).
