Im not saying that $1500 isnt much for me personally, but some out there who spend the big $ on parts for rebuilds then a new crank is the least of their problems. Go look in the for sale section and theres a few threads with parts in there like $13K for a block or $11K for a head...add each part of that into a whole setup and the $1500 for a crank suddenly seems insignificant.

agreed. . .its not cheap going fast!

yeah like I said $1500 is not expensive when doing a build with top $ parts. look at the price of the other gear and then decide if using a used crank which is potentially bent is worth it? of all the used RB26 cranks i've seen more were bent than those that were straight. I know a number of people who've bought used cranks only to have them checked and find them unusable and then do it again a couple of times before getting a good one. it doesn't take many used cranks or machining bills to get to $1500.

anyway for the original poster who wants some advice I will give some of my own experience.

fit some aftermarket valve springs. even tomei type A (type B are much better and worth the extra $). that will allow you some headroom if you want to rev and personally I would NEVER fit aftermarket cams with stock springs.

secondly, don't use the tomei pump with your stock capacity sump. yes you have it baffled but the tomei pump flows so much more oil than standard if you run high RPM for any decent length of time you are going to pump it dry. even with the 1.2mm restrictor oil will be pumping up many times faster than it can return to the sump.

consider fitting a larger sump to cope.

the other stuff all sounds fine and good choice on the tomei rods, they are excellent. there's no problem running 500-600hp (engine) on N1 pistons and rings either as long as it's tuned well.

if you do want to run some decent power and boost though I'd consider using a tomei 1.2mm gasket (or other MLS gasket but you already have lots of tomei gear so I suggested that one). even buy the tomei gasket kit. it comes with a lot of the other gaskets you'll need.

good luck. :)

Hello Beer Baron and thankyou for that info.

From what i have gathered from doing research these past few days it looks like im going to go with a Nissan subassembly assembled and strip and recheck it as the cost of parts alone is coming up to more expensive before assembly by 500 usd or so.

So thats 500usd more for a set of tomei rods included in parts alone.

Im assuming that Nissan has a greater mark up on parts then on a complete whole sub assembly unit.

never the less i wont need to check much accept check that they have cleaned the block correctly that means stripping the motor.

Then checking the clearances correct on mains and big ends etc .

Reason i say this is because there has been a number of people who have bought complete engines from Nissan and checked the clearances etc and found problems, as well as with the R type rebuilt blocks that also have had loads of issues including the engine i bought from a company called Flatwell racing, they supplied me a engine rebuilt from nissan and it was a dud.

So be carefull out there .

I have a nismo head gasket already are these no good 1.2mm?

I have a extended sump that also holds about 7.8 litres of oil i dont know if this is enough or not ?

What is the average sump extension size ?

Hope to hear back from you thanks for the advise Cheers

Ps the cams i had were being used on standard valve springs .

they are 264 degree cams intake and exhaust .

Hello, just a small update was looking at my cams and went on the greddy trust website .

http://www.trust-power.com/overseas/ov_products.html?cate=6&item=152

This is a drop in cam shaft and happens to be the cam shafts that i have model 13526204

Seems that i dont need uprated valve springs .

So im lucky on this one :)

will keep you guys updated when i get the short block assembly have to save up for it tough one .

Thanks for that heads up had me thinking there quite a bit.

lol this ones for keeping close to stock.

The beast will come in the form of a gtr32 possibly as i dont see the point in modifying this clean car lol.

It will be a weekend cruiser and some times a day cruiser.

But i do want to make horse power and im seriously thinking of going for a rb30dett sounds exciting but that will come later.

thanks for the help will post again soon once i have the ever so big lump of cash for the short block assembly.

Hello,

Just needed to ask, i have the crank and the grading on the top says BBBBBB and the bottom figures for grading are 0000000 can any one confirm why the top grading marks are no more numbers but letters ?

Is this a more recent update on the cranks and we dont have the new enough engine manual for it ?

    • The car/ECU will have all the sensor that it needs and expect to have. I think i do not have to explain to you how the Link is way better specialy if you have swapped engine   I just do not want to deal with any "problems" cuz i have only Nistune which i learned is not that great and in my case cant even deal with that speed problem (Link can) And of course it will be way more easier to tune and diagnose and safe. And for the ECU/speed problem...i dont know.
    • Per Mark Roberts of Sonictune: Mark Robert Author At this time, no. No ETA either 2016-17 models. You will be able to purchase and install a 2018.5+ TCU though   TCU purchasing and pricing info! As we near the release of TCU tuning, I am going to answer some questions I get asked often.   What do I need for TCU tuning? At this time, you will need a 2018.5+ TCU to be able to tune. If you have a 2016-to early 2018, you will need to replace your TCU with the newer version. One good way to know if your TCU is good is if you have auto upshift in manual mode in 1st gear around 6500 rpms. If your manual 1st gear goes to 7k rpm and will hit the rev limiter unless you shift, you have the older TCU.   Why do I need to buy another ecu license/phone flash if I already have it on my ECU tune? The TCU is its own computer module. It is completely separate from the ECU. Because of this, you will be required to purchase a TCU license and, if your tuner has it, the phone flash license required to tune it via phone/bluetooth.   Do I need TCU tuning? TCU tuning is NOT required. However, the faster your setup, the more it will assist in track and dragy time consistency.   If I’m ECU tuned by (tuner A) can I get my TCU tuned by (Tuner ? Yes, since it’s a different module and a completely separate flash, you can have two different tuners. However, it is highly recommend that you have both tuned by the same tuner. For me, my TCU tuning will directly complement my ECU tuning style and features and running my ECU and another TCU or vice versa MIGHT cause some issues. At this time and for the foreseeable future, I will only be tuning my current ECU tuned customers TCUs.     I have a SYVECS AWD controller. Do I still need it? Yes! The AWD controllers main job is to control your AWD system. However, with TCU tuning, you will no longer need the auto-shift function as that will be done through the TCU. The AWD controller will still be very beneficial for racers looking to maximize traction on the launch.     Shift schedule changes: holding gears longer at lower pedal input as well as max shift rpm changes. Please note, the new ECU race rom coming out will address 90% of the shitty drivability issues these cars have through custom maps from myself and Racebox—as well as others I am sure.   Increase shift speeds: as seen in the videos I’ve been posting, the TCU shifts much faster once tuned.   Increased shift pressures: as also seen in the videos, much firmer full throttle shifts.

    • The fancy pants red shock tower brace is finally incoming from MX5 Mania, getting it shipped from 'Merica has been a long and problematic process, and GWR, the 'Merican supplier will not ship directly to consumers outside of the US, Mania basically had to order a heap of them, the colour choice was silver, or red, and we all know anything red adds 5 killerwasps of dynotorques..... Whilst it does fit over a 2.5, and I've seen a few photos and videos of it being installed and fitting, google also says it might get real close to the FAB9 intake front runner, people in the US says it does fit with the FAB9 intake, except for one person who said it slightly touched.......so there is that.....LOL..... As it seems that I am the first in AU to have this combination of parts there's no local knowledge about fitment, so I'm just a willing guinea pig in this endeavour, I'll cross my fingers and toes and hope for the best In other news, I ordered stuff from China  on the same day I ordered the 23° silicone bend from Victoria, the stuff from China arrived a day ago, the 23° silicone bend is still travelling around Australia thanks to Australia Post, and "may" be here next week
    • Very good news...I contacted Racebox about it last night. My car is a 2016 so remains to be seen if it is compatible, requires a TCU swap, or is impossible.
