I love your loyalty to this project. I am not selling my RB26 bottom end now. :devil:

lol Thanks... its been 2 years in the making so no point giving up on it now..

Doesn't that tell you something ??

Yea I put it down to us increasing the oil clearance this time by another ½ a thou, and the fact when I tried it last time it was after It had spun a big end and a main bearing.

Anyway, I spent today doing as much as I could in the 36 degree heat! I spent a good 2 hours cleaning out the Sump and Head, I couldnt believe the size of the bits of bearing the I got out of the sump, I ended up filling it with water and putting a few welding magnets in the water to pickup all the small particls and large flakes a bearing. The head took the most time as I didnt have the tools at home to remove the valves so it flushed it slowly cleainng out all the oil and any small traces of bearing I could find... which was only 1 or 2 specks.

I installed the Sump, Oil pump, Rear Main Seal, Exhaust manifold, Turbo and the Head today. I held off with the water pump due to a couple of the bolts looking a little worse for wear I shall pickup some replacments from nissan this week.

Anyway heres a couple of picctures of where I am upto.

I have been looking over my figures for the head bolts of what I had written down a year or so ago, can somsone confirm these for me.

1. Tighten to 22 ft/lb

2. Tighten to 80 ft/lb

3. Loosen bolts completely to 0 ft/lbs

4. Tighten bolts to 22 ft/lbs

5. Turn bolts 85-90 degrees clockwise with an angle wrench, or tighten to 76-83 ft/lbs when torque wrench is used.

From looking over the nissan manual these appear to be the rb26 standard torque settings, and ARP recommeneds 109ft/lbs as the final figure is this tru for the rb20 also?

I am using ARP studs for the head.

85ft/lbs with moly lube will be sufficient.

Thanks anyway, The head is already bolted down and studs have 30w on them. I used the last of my molly lube on the ARP rod bolts.

its generally 20-30 more ft/lbs when using 30W oil for that size stud...so 109ft/lbs sounds like the right torque for 30W oil.

No updates really...

The engine is sitting in my garage while I contemplate If I should do a external oil pump setup on it or just a billet pump.

The clutch is off at Jim Berry's being rebuilt so once I work out whats going on there It will be back in and running again..

Could always drysump it :(

Any ideas what I should do?

Nothing much to update, Spent last Sunday putting the engine back in the car hat a mission it is to line the gearbox up with the engine! I wont be doing that again in the car.

Today I was planning on getting it started etc so got all the wiring done, water and oil lines hooked up radiator and starter motor in... put 7 ltrs of oil in and started to fill the radiator and my feet were getting wet! Somehow I have lost the plastic bung out of the radiator I suspect one of the dogs as picked itup as a chew toy like they have done with the silicon tubes.

So I am on the hunt to find a new/replacement bung for the ASI radiator, I have emailed ASI so hope I can get a replacement from them.

    • So the original radiator is leaking now. Looking at getting a fully aluminium one next. Am I correct in saying that the Series 2 Auto Stageas have a separate trans cooler from factory (located in between the rad and intercooler in my previous post/message).   Currently looking at Fenix $460, Blitz $700, GReddy $800, and KoyoRad $740. What are everyones thought on Fenix ( ive read a few comments saying theyre cheap Chinese rebrands etc and how their build quality is... well.. chinese...)  compared to the others? Worth the extra couple hundies?
    • Man, different parts but the same numbers is terrible @dbm7! And it doesn't help that most online shops don't list the part numbers at all. They just give a list of compatible models...
    • Slow when hot could also be because its getting more dynamic compression, OR things are getting a bit tighter once it is all expanded. If it were an earthing issue, typically I'd expect you to have it have issues all the time. Unless it's really a combination of both things. Where the higher compression, and things being a bit tighter, is giving that bit of extra load and you do need a slight clean up on the cables/connections.
    • Yeah, this is one of the most annoying things about nissan part numbers... I've got an unrelated example... Image is of the AT output shaft ~ they have the same part#, but clearly the shaft on the left is beefier design to that on the right ...the difference (essentially) is the 'lighter' shaft on the right, is for engines up to RB25DE (this includes RB20 variants) : the shaft on the left is for RB25/26DET(T)....are they interchangeable? Yes...but obviously one shaft is going to be stronger than the other...and, the lighter shaft is around USD115, but the heavier shaft closer to USD150...same part#... ...epc-data usually tells a tale ~ the amayama listing for 39100-23U60 has a note "Longest side is between 60 and 105 cm" ; no such info is there for 39100-23U70 ...and given the great disparity in price between the 2 parts, it makes me at least curious (to the point of caution) where the 'extra money' went? ...ie; these 2 parts have a cost difference that (to myself at least) isn't explained by 'plastic boot'...ie; with amayama there's AUD700 price difference ...plastic versus rubber?...I'm not seeing it like that...and 60cm ~ 105cm...??...that's a huge disparity....something hinky going on here... I'd try searching by VIN, not model... /2cents
