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.

      Duncan's V37.......race car?

      By MBS206 · Posted

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      Duncan's V37.......race car?

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
