Hey guys, threw a rod on my skyline and am in the process of a rebuild. I'm going for stock internals at this stage due to the fact I'll probably sell it for a gtr upgrade in 6 months or so when I have the money. The question I've come here to ask is, what is a safe amount of power to run through stock internals with my following mods, I really don't want to push it to it's limits, although would love to be able to make some decent power without worrying about something going bang again. If someone can help me out a bit, it would be much appreciated!

Specs are as follows

- Gtx3582r turbo, mild Steele exhaust manifold, all custom alloy piping, HDI intercooler, Greddy intake manifold with 90mm throttle body, Bosch 1000cc injectors, split fire coil packs, turbo smart 45mm hypergate wastegate, turbo smart supersonic bov, m spec alloy radiator, Apexi power FC ecu with z32 Afm and hand controller, full 3 inch turbo back exhaust with dcat, walbro 500kw fuel pump, twin place ceramic clutch. And it's a series 2, 33 gtst.

If you're going to sell it in six months why take a risk? Sell off all the gear you mentioned and return it to stock - you'll probably make more money that way and less chance of blowing it up.

Thanks for the replies so far. At this stage, still unsure whether I want to keep it or not. Will be finding out how much it is to go down the forged track, but if its ridiculous amounts of money, I dont think its worth it unless im aiming for big power. The question is, provided the engine has a fresh rebuild, would it be able to safely handle 270-280rwkw? Thats as far as I really want to go, power wise. I bought the car for 7 grand, so I dont mind spending a bit of cash to make it reliable, so maybe forged is a good option?

bit off topic but why the gtx3582 if your going for sub 300kw? or did it come with the car? Maybe try selling that off and getting something like gt/gtx 3071 will be much better to drive at that power level. That powerlevel a good stock 2nd hand motor that hasnt been rebuilt will do it no worries so a fresh one definately no problem aslong assuming things like your tune and maintance is kept up.

Hey, yeah the 3582 come with the car. And thanks, that's definitely something to consider. I've got a pair of tomei 256 poncams here to put in her aswell. With the fresh rebuild I was going to run 300+ but just unsure on how reliable that is, even with a good tune and maintenance kept up to date, I've heard many stories of idiots blowing their engines... But I kept in mind these are guys that thrash their cars redlining flat every gear. I only really drive this car on the weekend. The guy that had it before me thrashed it a bit by the looks of things, so just trying to do things right this time. I would love to go forged for that extra security and peace of mind. So nothing's set in concrete here, just need some help on what path is the wisest to go down. Thanks for the info so far.

Yeah what you say makes complete sense. I'm a little undecided whether to keep it or not. So what I'm saying is if I do rebuild it, I will probably end up keeping it for a good couple years. The main question is, what power can I aim for with stock internals that's going to be reliable? With the mods I have I can easily achieve 320+ But is that real smart?

I think its been said on this forum many times that a std rebuild engine is not always as reliable as a std factory built engine, and there are lots of people running 280-350rwkw on std engines, for how long is down to tune and maintenance and how you treat it

Went and talked to my mechanic today, who's a good friend of the family. The damage done to the block is somewhat repairable but he has also given me the advice many others on here have, and that's to just drop another rb25 in. His already found me an engine for $600 and it's in really good condition, don't ask me how he pulled that one off, because I thought they go for around $1200. His advised me that if I'm going to keep the car, to get a set of forged pistons and rods, head gasket. But also as many of you said, if I'm going to sell, drop the engine in, a tune and sell her off.

    • What copper washer do you guys use on the bleeder bolts? The existing one I have I had no idea where to find it in a local store, I did buy some online but that are only 1mm thick whereas my old one is 2mm+ thick and when I put the new washer out and squeeze the top radiator hose I can hear a bit of air but not with the old one. Does this matter? The new one doesn't leak, but the inner diameter is a bit loose whereas the old one threads on the bolt.
    • Howdy all, after being out a few weeks ago on a spirited drive in my GTR I have 2 issues that oddly have appeared at the same time. Whilst accelerating quickly through the gears all of a sudden i’ve lost power at the top of third gear (below redline around 6000rpm) for no obvious reason.    From that point onwards the car has been running rich on idle, won’t really rev under load without a ton of black smoke and the odd backfire, and dying as a pull up to a set of lights unless I keep the revs up around 1500rpm. In addition when shutting down the car that same night (I was 10 minutes from home) I noticed one of the turbos was significantly noisy on wind down when shutting off the engine. After letting the car cool down overnight it starts up fine, although once it gets to temp the revs start to creep up and down, the exhaust is darker than it should be and it also sounds like it’s running rich (fat note) I’ve put a new set of plugs in it - no change, the old plugs all seemed OK with two of them being somewhat richer/fueled up than the other 3 with 1 being borderline. I’ve smoked tested the intake system via the front of the Turbos, found a split vacuum hose going to the factory boost gauge sender, which I have since replaced.  Also found another leak on the gasket coming off the rear turbo outlet, have also replaced this. After fixing both of these leaks - still have the running rich issue. I’ve also tried another pair of AFM’s - no change here After pulling off the front turbo intake pipes, there is obvious shaft play in the front turbo, which now hisses loudly on light revvs although I can’t see why this would make the car run funny even under idle. I’m curious to know why it’s running rich before I potentially replace/rebuild turbos. The car is completely stock <50,000kms  other than an exhaust. Oil and coolant are all clear. I haven’t bothered with coil packs as it looks like they won’t be the issue due to condition of the plugs. Any help appreciated as I cry myself to sleep!
    • No probs at all. I used to love trying to dig up obscure info for those in need where possible going back 20+ years on SAU.  I did have another look and couldn't come up with any closer match. I'm leaning towards those skirts in your first pic are custom fitments, cut down/extended or from another car entirely and modded to fit an R34 sedan. I would've thought someone in Japan had them and taken a photo at some stage over the last 2 decades but there's nothing. Someone out there must know surely.
    • Welcome mate. Any pics? Even with a DE I'd be well happy if I had that as a 1st car.
