I'll share mine when I get back to the house. Still working on it and have done all the work myself save for machining the head for the valves and installing valve guides. Yes it's expensive. The hypertune V2 was by far my biggest adder of costs and potential headaches so far. Haven't touched the trans yet!

Hahaha long!

Was kinda talking about machining costs, assembly costs, porting costs ect

Tomei stroker $5,800

Tomei oil pump $1,500

Racepace Motorsport sump $1,500

Machining and assembly $3000

Head $10,000

Custom cams $1,200

ATI balancer $1,000

Nissan gasket kit $400

Water pump $200

Nismo 0.9 mm head gasket $400

Thats about it off the top of my head.

Forgot headstuds.

Also you did't use the spool stroker kit :P

Add a few thousand for miscellaneous stuff like new seals, gaskets, timing belt kit etc. I'd also say that machining and assembly cost is maybe a tad low?

Would DEFINITELY have done this had I seen it before doing mine myself. They have the pistons to match their cnc combustion chamber as well.

Tbh, as a BC 2.9 owner I wish I just bought another standard engine and didn't rebuild it at all.

Because the 4 times its been apart since could have been avoided, and yes while laggier I would have had way more time you know, actually drive the car and spending the money on track days, becoming way faster behind the seat with a 2.5 than 2.9L myself is today on a forum.

That would be nice but aren't they like 12k for a bare block?

How come it's been apart 4 times since? My biggest fear with building a motor is getting the right person to do it, to many people out there think they know what they are doing, take your money and then you end up with problem after problem.

So a stock 34 motor you reckon lol?

For what reason was it pulled apart 4 times ?

For what reason was it pulled apart 4 times ?

4 different reasons.

Point being as the poster a few posts up above said, your engine is only as good as the person who built it. And the more custom things you do, the more you are reliant on how good your builder is to get it right. I had this exact option many years ago, in the hands of someone who was very highly rated on this very forum, at the time.

Put another stock engine in, or for very little money go forged which will surely last longer.

And for not even that much more, why not use a 2.9 kit? I mean, it's apart, and it seems like sound logic.

Sure, if the builder is great your RB28 can still be fantastic.

But yeah. It doesn't always end up that way.

As a result, I am a proponent of staying off the unknown path as much as possible. Saving Engine rebuild money and putting it into DIff, Brakes, Suspension, Tyres, and track time will result in a faster car, even if you make 320kw on -9's instead of 450KW on a 28 or a 30 on a nice twin scroll single.

One of the cars will be left in the dust in the above example and it won't be the 26.

    • No, I refuse to buy their cheap ass crap! I do need to order a bunch of different nuts/bolts to refill my nut/bolt wall though. Maybe you could go for a walk through Bunnings for me? (Or send me some stuff from your work? )   I really struggle to work out how the US standardised to Metric in what the 70s or 80s, and yet, half a century later, there's been little done to actually bring it into fruition. It truly baffles me    On the whole Fastenal thing, I went reading their site (My god they sell a lot of varied stuff!), and it seems like it really depends what store you're near if you can walk in and just grab a few small things, or if that branch is primarily distribution with only a small window of "counter time" available (if at all). That definitely makes it harder, as move locations and it drastically changes your ability for success   For things like your M6x1.0, if you want to work on your own Skyline, and you also have a "home workshop" I'd recommend setting yourself up a small Nut/Bolt wall/section. It doesn't even need to be big at all. Most things depending on the diameter, will be a specific pitch, like the M6x1, M5x0.7 etc. Bigger bolts is mostly 1.5, except for a small number of things and that will come down to torque. From memory bolts for the brake calipers (and other things that need a lot of torque) will end up being a 1.25mm pitch. Save up a few dollars, and order a range of nuts/bolts. If you want to minimise cost a little, buy something like M6 x 40, and M6x70mm (1mm pitch) in both. In addition, buy yourself an M6x1mm thread chaser. That way you have long bolts that you can cut down to size, and then chase the threads out. Funnily enough, I find what I'd pay here for ordering 5 bolts, I can pay about 50% more and you'll get 100 of them.   If that doesn't quite work out due to space / ability to buy plenty up front, then each time you need some bolts, order 100 of what ever you're getting. Put them in clearly marked containers. Over a few years, you'll acquire plenty of different sizes, and will end up ordering less and less. And the cost for 100 bolts won't be much more than you paid for your 5 you needed to order anyway  Just takes a little planning ahead, by investigating what nuts/bolts you'll need, and ordering them before doing the job.     Edit: If it's also primarily for working on just the Skyline, for some reason my brain is screaming that at some point, either Nissan, Nismo, (Or possibly a third party) was selling a "kit" of every nut and bolt in a Skyline, purely for people restoring/rebuilding. It'd likely be quite expensive, but would give you every/any nut/bolt you need for stock/factory things. I'm not sure if it's still available, or even if it actually fully came to market, it's just something niggling in the back of my brain that you could look into further if that sort of thing interested you? (It might have been for the R32 GTR or something specifically too, and not just any Skyline)
    • 90lb/min @ 20psi is wonderful, not so much of a problem with the G35-1050's compressor efficiency (aside from how bad they roll back at higher pressure ratios).  The issue is more to do with the turbine's flow, which is why I'm not sold on going an even higher flowing compressor with the same turbine.  I'd say go back over Motive DVD's testing of the G35 1050 and Hawkins's comments regarding exhaust back pressure issues with it, I'd need to go back but I have in my head he went to the biggest hotside and ended up sacrificing a lot of spool (so it ended up behaving like a bigger turbo) and still had EMAP issues.  I've heard various other experiences along the lines of that. At this stage at least I rate all I've seen about Xonas (for transparency I've not used one directly, but I have spoke plenty with people who have) to have low exhaust restriction for the response they offer for any given setup - basically they allow the engine to breathe, which is good for the engine and makes making power a lot easier.  You arguably don't have to even push quite the same amount of airflow through an engine to make the same power if you don't have the bum plugged up with exhaust gas struggling to escape the engine due to an underflowing turbine.   In terms of reliability, to be fair I've had great luck with Garrett turbos as well - my GT3076R lasted forever, then I sold it and the next owner had no issues, then that car got sold and it was still going strong last I ever heard about it.  The trick is with the old GT-series turbos the compressors etc were no way near as efficient as what we have these days, it was almost hard to push them into severe overspeed situations without having a boost leak or something - and that is what often starts the failure situation.    In terms of your G35 I'm pretty sure you're running yours within sensible limits, something people with Xonas and Precision turbos aren't often so inclined to do.  The "compressor maps" are "Joe blogs ran 45psi through his 6466 so I can do the same" and built their setup to send it to the moon.  I've seen EMAP and compressor speed data where people have actually set that stuff up on Precisions and Xonas which have been run hard and the comp speed numbers are very very exciting at times - like I've seen 76mm Precisions run at rpm that you ideally shouldn't run a G35 1050 lol.   I know people who have run G-series Garretts hard and hard a failure, then replaced them with Pulsar turbos as a cheap "get it going" stop gap with the intent of doing a proper upgrade when THAT fails... and are still running the same thing.   Like anything, ymmv and it's not always to do with the quality or trustworthiness of said product. I've been provided with a bunch of compressor maps for Turbosmart turbos and will update my list based off that, they could prove to interesting reading and an interesting alternative as well.
    • Just cage it, call it a race car, and then fall in love with the chirp chirps through pit area!   Also, this is coming from someone with a completely locked diff...
    • I still have an old R32R left over from when they were a thing in the early 2000's. It was, for its time, done about right. But its time was 20 years ago.  I did try and update it a while back but it was cruelled by a (recommended) muppet of a tuna who couldnt tell his MAP from his TPS. The original spec was: Power FC, 700cc Sards, Nismo pump, 2860-5's, cams (Basically Poncam A's), Z32 AFM's and a half sorted oiling system. Thereabouts 430rwhp irrespective of what was done. So, yeah, very 1990's. I eventually got sick of it not being very refined and bought a Link G4 PNP with some 1000cc Bosch injectors. This was tuned badly and I put the car in the shed for a few years whilst I sulked and went and did other things. Ive come around to the idea of getting it going again so it has a new gearbox installed and some other minor things in the planning. So my questions are, variously (In the context of keeping the Link) What other sensors should I be running eg It has no wideband on it at the moment, nor fuel pressure. $? Is it worth chucking the old ignition system (ignitors etc) for new ignition coils? $2k? Cam/crank angle sensors? Can keep the aircon? $? Anything else? Sorry to launch another what should I do with my car thread but, you know, what should I do with my car? Random photo for historical context.
    • If you think that's harsh, go experience a KAAZ 🥲 Thoughts and prayers for Dose. I had mine modified by a diff shop to make it less brutal, no idea what they did but it's not as brutal as before. The Asian in me was being tight before and went KAAZ instead of a Nismo, lesson learned.
