well one of my points is that you dont need forged pistons or different rods to make 700 hp from an rb 26 that is a proven fact you need turbo / 's to suit and a fuel system

cams you can reprogram the r32 gtr ecu or you can fit a plug in power fc or what ever ecu you like.

take for example an rb 26 for sale fully rebuilt stock pistons 272 cams balance, ecu etc 7500 turbo /'s to suit 3-4k injectors 1 k cooler 1500 ,fuel pumps 600 add 2k for things forgotten am I close?

hey squizz,

i didn't imply that the RB20 box will be good for 10's, i was mearly saying that it will be a simple bolt-up operation if he goes the RB30 conversion which will be nice for the street.

do u think a 3 spd auto with a 4000rpm converter, factory 4.11s in the ass is streetable?

meggala,

you're right, although $7.5k would only be for the engine w/out ECU/loom/injectors, etc, twin bb turbo's would cost more on the $4-5k, full fuel system would be about $1k, ECU (Power-FC) ~$1.5k or Autronic/Motec ~$3k, injectors - ~$1k and you've forgotten manifolds and external wastegates (needed for this kind of power) which would be more in the field of $3-4k.

So, you're looking at about $17-18k+ for a standard (reco'd) RB26DETT engine where for less than that, you'll have a fully rebuilt and forged RB30 bottom end along with the RB25DET which is very capable of producing the stated ~700hp reliably.

Also, given that it is a larger capacity engine (3000cc vs 2600cc) there will be more torque and it will produce the power easier, with less boost and rpms.

Speak to Mattlowth, he'll tell u what it costs and the capabilities of the engine. his is making 320rwkw (430rwhp) on only 16psi.

I'm sure if it's pushed a bit more, it will comfortably and reliably make over 500rwhp.

Fuel stores the potential energy that gets combusted and eventully makes the car move. To move the car faster you need to convert more chemical potential energy into mechanical kinetic energy (ie make it more efficient with the same amount of fuel) or alternatively let more fuel and air into the engine to combust (which is gonna be inevitable if were talking a 10 sec car).

Getting a car that runs 14s into the 13s could be done by making the engine more efficient (ie aftermarket ECU) without a significant increase in fuel consumption, but to get from 14s to 10s is gonna require a shit load of fuel to produce the power required hence making it a crap daily driver (just one of the reasons anyway).

I hope that makes sense...

riggaP,

Yes I understand the fact that potential energy leads to kinetic energy, this is the same for everything that moves, but increasing fuel and oxygen to create additional power doesnt just relate to physics. Remeber we are only talking about the power/fuel ratio.

Of course a moving car is related to physics, but when talking about the AMOUNT of fuel that is required to put out an AMOUNT of power, it is not just physics but also involves mathematics and chemistry.

The additional oxygen and fuel is used to create a greater CHEMICAL reaction, thus this reaction uses more fuel and creates more power. The fact that this reaction creates kinetic energy is irrelevent, because the consumption of fuel has already been determined from the chemical reaction.

Thus an increase in power is a result of a greater chemical reaction, where a greater volume of chemical components are required.

I agree that physics are involved, since the final output is power and cars move! but the ratio itself relies on a chemical concept, the physical concept is simply the result. I think what you meant was that it is simple science.

I don't mean any harm or flaming, all in good fun. :)

      Baron's R34 GT-R build thread - car in Japan for 5 years -_-

      By soviet_merlin · Posted

      I'd be curious to hear more. Otherwise, have you driven a modern x-trail? I wonder how it compares. Here in Australia they are/were popular for rentals and fleet vehicles. I have been in some and my impression was they are bad. But, this may have been very different in the 2000s at a good trim level. Twenty years is plenty of time to make the model worse. I do very much agree with the 2 silver cars in the garage approach. But, not driving because it's too hot would not leave a lot of time in the year for many Australians. I don't think you need to worry too much unless the car has actual issues with overheating.

      Baron's R34 GT-R build thread - car in Japan for 5 years -_-

      By BaronOBeefdip · Posted

      Back again. I returned to Japan in Jul/Aug to spend time with the car on my birthday and remind myself what all the sacrifice and compromise is for. It happened to line up with the monthly morning meet in Okutama, which I have been wanting to go to for a long time. It's a unique event at a unique spot with really rare, interesting, and quirky cars. It's where all the oldheads and OGs gather. The nighttime scene at DKF certainly has its place and should be experienced if you're into cars, but there's too much bad attention and negativity around it now. IMO the better time is Sunday morning at DKF or Okutama; it's more chill and relaxed. I'm glad I was finally able to go, but not sure it's worth the drive from all the way from Nagoya immediately the day before, unless I was already staying in Tokyo for the days right before the meet, because you have to wake up quite early to make it in time. Funnily enough though I didn't drive the car all that much this trip because it was just too damn hot. While there were zero issues and running temps were nominal and the A/C was strong, RBs already run crazy hot as it is. Sure, it took it all like a champ but something about driving these cars in the ridiculous heat/humidity bothers me and makes me feel like I'm asking too much of it. I'm just me being weird and treating the car like a living thing with feelings; I'm mechanically sympathetic to a fault. Instead I was mainly driving something else around - a KX4(silver) 2001 X-Trail GT, that I acquired in May. There's a few different flavors to choose from with Xs, but visually it's the Nissan version of the Honda CR-V. Mechanically it's a whole different story as this, being the top-trim GT, has an SR20VET mated to a four-speed auto and full-time AWD! It was a very affordable buy in exceptional condition inside and out, with very low mileage...only 48k kms. Most likely it was owned by an older person who kept it garaged and well-maintained, so I'm really happy with how it all worked out. It literally needs zero attention at the moment, albeit except for some minor visual touch-ups. I wanted something quirky, interesting, and practical and for sure it handily delivers on all three of those aspects. I was immediately able to utilize the cargo and passenger capacity to its full extent. It's a lot of fun to drive and is quite punchy through 1st and 2nd. It's very unassuming -in the twisty bits it's a lot more composed than one would think at a glance- and it'll be even better once I get better tires on it(yes, it's an SUV but still a little boat-y for my liking). So...now I have two golden-era Nissans in silver. One sports car and one that does everything else; the perfect two-car solution I think👍 The rest of the trip...I was able to turn my stressed brain off and enjoy it, although I didn't quite get to do as much as I thought. I did some interesting things, met some interesting people, and happened into some interesting situations however, that's all for another post though only if people really want to know. Project-wise, I went back to Mine's again to discuss more plans and am hoping to wrap that up real soon; keep watching this space if that interests you. Additionally, while working in the tormenting sweatbox that is the warehouse, I was able to organize most of the myriad of parts that my friend is storing for me along with the cars, and the 34 has a nice little spot carved out for it: And since it can get so stupid hot in there, that made it all the more easy -after I was standing there looking at the car and said 'f**k it'- to finally remove all the damn gauges that have mostly been an eyesore all this time. Huzzah. The heat basically makes the adhesive backing on the gauge mounts more pliable to work with, so it was far less stressful getting this done. I didn't fully clean it up or chase the wiring though; that will happen once I have the car in closer possession. Another major reason to remove all that stuff is to give people less reasons to get in my car and steal s**t while it's being exported/imported when/if the time comes, which leads us to my next point... ...and that is even though it's time in Japan is technically almost up since it's a November car and the X would be coming in March, I'm still not entirely sure where my life and career is headed; I don't really know what the future looks like and where I'm going to end up. I feel there's a great deal of uncertainty with me and as a result of that, it feels like I'm at a crossroads moreso now than any point in my life thus far and there are some choices I need to make. Yes, I've had some years to consider things and prepare myself, however too much has happened in that time to maintain confidence and everything feels so up in the air; tenuous one might say. Simply put, there's just too much nonsense going on right now from multiple vectors. Admittedly, I'm struggling to stay in the game and keep my eyes on the prize. So much so in fact, that very recently I came the closest I ever have before to calling it quits outright; selling everything and moving on and not looking back. The astute among you will pick up on key subtext within this paragraph. In the meantime I've still managed to slowly acquire some final bits for the car, but it feels nice knowing there's not much left to get and I'm almost across that finish line; I have almost everything I'll ever want for my interpretation and expression on what it is I think an R34 should be. 'til later.

      Thanks for that, hadn’t used my brain enough to think about that.

      Also playing with fire if they start to flow more air down low than what the stock twins can. It's not even up top you need to worry, it can be at 3000rpm and part throttle and it's getting way more flow than it should.
