If you are so concerned about displacement, get a Clubsport!!!

or alternatively:

M3 is 3.2 or 4.5 (?) if it's the V8

2.6x1.7 turbo multiplication as per motorsport regs = 4.42, so basically the RB26 is equivelant to an NA 4.4l, but is even easier to get HP out of. Seriously get the car, drive it for a bit, play with what you get then decide what you want to improve. if it is STRICTLY a road car what the F do you need more than 300hp for? even my stock R32 with a pair of -7s is quicker that all bar the top Porsches/Ferraris/Lambos etc to 100... The way you are talking I would personally be suggesting maybe this

HAHAHAHAHAHAHAHAHAHAHAHAHA

Hey mate I kind of get where you're coming from, you had the evo which was a beast and don't want to take a step down. But that doesn't mean you should throw money at a giant step up either. With the amount of money you seem willing to throw at this you should have the fastest gtr in the country bar a very select few.

How many killerwasps did the sti have btw? Sounds like a beast! Which model was it?

The 3.0L rb26/30 is really really common compared to more exotic engine builds. I'd just be doing this with clever turbo choices and a good tune. Is there really that much of a difference between 3.0 and 3.15 in the real world?

No.

Great point though.

Mines an 87mm bore, stock is 86mm.

Drivability is the key here. Also GTRNUR has a good motor in development around that capacity.

No point having a laggy 3L, a responsive 3L will be way down the street before you have much going on.

Capacity isnt the be all and end all (although i highly doubt the OP realises this judging by his posts). Turbo choice, cams, part selection, rod stroke ratio etc all play their part.

I personally would love to one day to the 3.0L conversion myself (talking years down the track here). But I just want to know how it all goes together.

OP, see how n1gtr has >28000 posts, that tends to indicate a fair bit of knowledge.

Another point: you can spend as much as you want on a car but an experienced, knowledgeable person can build a faster, more reliable engine/car for 10% the price.

Called a couple of GTR sellers yesterday, I'm trying to a get a pretty cheap one even if the KMs are high, I'm getting rid of the engine anyway. I don't mind paying 40-45 even 50k but does anyone know any GTR's from 35-40k? I mean genuine R34 GTRs. If not then I have couple of high probabilities.

Galois I'll dig up videos I have of my STi, it was an 04.

The other option, just as a point of interest, would be buy an r33 gtr and spend the savings on mods as well making a real weapon lol. Not sure why you want to rush into this so quickly though, it's not like taking things slowly is going to waste your money. You don't even own an r34 gtr but you already don't want the engine...

I think I'll be getting the OS Giken 3.15 motor, it seems to be coming from a solid company and I calculated it, I could make it work into the budget. Now because this thing is so expensive I want the best tuner in the country. I would be willing to go interstate for a tune if its necessary. Does anyone know a good tuner with a good workshop?

I tell ya what, send me $125k and I'll build it for you and send it back down. The price includes the purchase on the car you don't have yet.

I have everything I need to build you an absolutely reliable rocket;

R34 GTR V-spec

"High Octane" stroker

Assortment of turbos (we'll stick with low-mounts)

I'll put a Autronic in it

I'll install a fresh PPG dog box we have here.

We'll dry sump it.

We'll tune for E85.

it'll make around 500AWKW and will have usable boost under 2000rpm, and rev to over 9k.

Deal?

Galois the R33 is not an option, I know I'll get abuse for saying this but compared to the R34 it is kind of ugly, personal opinion though. I want the R34 for the looks and the performance, if it was just performance I'd get the R32. I considered the Supra too but I've made up my mind.

For the amount of coin your looking at laying out, if you can see your self in an R32 then maybe you should do it.

Because then you would have the money to bring it upto spec in any way you find it deficient.

Plus enjoy the lower weight.

can i have your autograph ?

Does anyone know where I can rent like a little workshop to work on the car, some things I can do without a mechanic. I just need a garage kind of place. They don't seem to rent places for 2 weeks I checked it's all per annum rents and I don't think they would think it's worth it. I just need a big enough place to paint, replace small things etc. By the way I have experience so that's not the issue, I can't do it at home, not enough room.

I just saw the Autosound LS1 powered R34, it's a twin turbo and it weighs less than the RB26 with more displacement. Now Autosound did do this build so it is possible and I suspect it's alot cheaper than the OS Giken RB315. Questions is with this build can the 4WD remain. The 4WD is one of the R34 GTR's best features, can the LS1 work with the 4WD? This sounds like a stupid idea but look at the facts.

1. Cheaper Build

2. Lighter Build

3. More torque

Now I would only want 600-650hp but the torque, the weight and the price would really make this tempting. I love the straight-6 in the R34 but I've looked at the price and this seems feasible. Street legality is obviously laughable, this thing is like 125% increase in displacement but we'll talk about that later. What do you think?

I think most people on here think you're getting way ahead of yourself and just writing off an engine you haven't even bought yet mate. That said, if you want to spend this much and don't want that engine why not put something really interesting in.

Isn't the ls2 a better option then the runaround ls1? Can't remember, read about a similar idea ages ago.

Why not put a supercharged 6L monaro engine in? More torque than you'd know what to do with. Not sure how much they cost, but what about one of the audi, merc or bmw v8s? Mountains of torque and 8k redline stock.

Obviously you are thinking too small. I would be looking at a new BMW N74 V12. It's the engine that comes in the 7 series BMW twin turboed and a 7 speed gear box. Awesome torque and power. Might be a bit of a hassle putting it into an R34 though...

You could always just buy an R35 instead of a 34. 3.8 twin turbo has a dickload more torque than a 26 and you would probably spend similar money trying to jam an LS engine in there and make it work with the awd system.

Another idea would be to GTFO...

    • 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.
    • Hi,  Just joined the forum so I could share my "fix" of this problem. Might be of use to someone. Had the same hunting at idle issue on my V36 with VQ35HR engine after swapping the engine because the original one got overheated.  While changing the engine I made the mistake of cleaning the throttle bodies and tried all the tricks i could find to do a throttle relearn with no luck. Gave in and took it to a shop and they couldn't sort it. Then took it to my local Nissan dealership and they couldn't get it to idle properly. They said I'd need to replace the throttle bodies and the ecu probably costing more than the car is worth. So I had the idea of replacing the carbon I cleaned out with a thin layer of super glue and it's back to normal idle now. Bit rough but saved the car from the wreckers 🤣
    • After my last update, I went ahead with cleaning and restoring the entire fuel system. This included removing the tank and cleaning it with the Beyond Balistics solution, power washing it multiple times, drying it thoroughly, rinsing with IPA, drying again with heat gun and compressed air. Also, cleaning out the lines, fuel rail, and replacing the fuel pump with an OEM-style one. During the cleaning process, I replaced several hoses - including the breather hose on the fuel tank, which turned out to be the cause of the earlier fuel leak. This is what the old fuel filter looked like: Fuel tank before cleaning: Dirty Fuel Tank.mp4   Fuel tank after cleaning (some staining remains): Clean Fuel Tank.mp4 Both the OEM 270cc and new DeatschWerks 550cc injectors were cleaned professionally by a shop. Before reassembling everything, I tested the fuel flow by running the pump output into a container at the fuel filter location - flow looked good. I then fitted the new fuel filter and reassembled the rest of the system. Fuel Flow Test.mp4 Test 1 - 550cc injectors Ran the new fuel pump with its supplied diagonal strainer (different from OEM’s flat strainer) and my 550cc injectors using the same resized-injector map I had successfully used before. At first, it idled roughly and stalled when I applied throttle. Checked the spark plugs and found that they were fouled with carbon (likely from the earlier overly rich running when the injectors were clogged). After cleaning the plugs, the car started fine. However, it would only idle for 30–60 seconds before stalling, and while driving it would feel like a “fuel cut” after a few seconds - though it wouldn’t fully stall. Test 2 – Strainer swap Suspecting the diagonal strainer might not be reaching the tank bottom, I swapped it for the original flat strainer and filled the tank with ~45L of fuel. The issue persisted exactly the same. Test 3 – OEM injectors To eliminate tuning variables, I reinstalled the OEM 270cc injectors and reverted to the original map. Cleaned the spark plugs again just in-case. The stalling and “fuel cut” still remained.   At this stage, I suspect an intermittent power or connection fault at the fuel pump hanger, caused during the cleaning process. This has led me to look into getting Frenchy’s fuel hanger and replacing the unit entirely. TL;DR: Cleaned and restored the fuel system (tank, lines, rail, pump). Tested 550cc injectors with the same resized-injector map as before, but the car stalls at idle and experiences what feels like “fuel cut” after a few seconds of driving. Swapped back to OEM injectors with original map to rule out tuning, but the issue persists. Now suspecting an intermittent power or connection fault at the fuel pump hanger, possibly cause by the cleaning process.
