Very nice. Saw it at the sau dyno day last year, and it sounded mad. Bet you suprise a lot of people when it just goes!

And maybe a properly bled ATTESA system!!

All the bits on the table, not going back in. Probably sell the rods. And Spool rods I'll be getting.

Getting ACL's from rocket tomorrow arvo. Let the $$$$ roll!

Ha ha, true you are, they are cheap these days.

As long as you ain't taking the mickey, here's why. The internals are rotating at a thousand revs at idle. The crank, rods, pistons are throwing off oil that has lubricated them as well as oil draining from the head oil returns. This all ends up back down in the sump along with frothy aerated oil from the turbos. The oil level will not be true as it will be mixed with air and sloshed around in the bottom too. It may bubble into the dipstick tube and run up the dipstick to give a false reading. Cheers.

Check it with your engine off. Oil sloshing around when engine is running?

No problems just cost time and money for labour, new gaskets, sealant etc, but you will need to hone the bores to suit the forged pistons to get piston to bore clearance right and bed in rings as far as I know.

Mine were always off. Still did it. Tried the old extra ground to the ignitor trick, no good...... Carton to the person that gets rid of this damn hiccup for good!

Yep, they ain't cheap. I was going to keep stock rods and put bolts on em too but after all the mucking around, I'll just end up getting some spools. New head bolts might be what I'll be doing. Will have to check funds lol.

I want to know how important using head studs, (eg ARP) are compared to the stock hex bolts which seem to be pretty good (600HP at crank). Especially if used with a metal head gasket. Don't want to replace things that don't need changing for no reason, especially if aims are not 700HP+ and 34 PSI. I know it's a peace of mind thing, it all adds up though!!

Whoa, the bearing prices are over half of what I got quoted at Repco lol....(almost passes out). Cheers for the info. I asked about an ACL gasket rebuild kit today and they include the headgasket, but I'm planning to use a different one. Seems like a bit of a waste.

Doh! It sort of had to happen anyway.

Cheers. Just do'in it Jap style LOL!! Now to save lots of plastic notes up......

RB26DETT r32 / 90 AMPS

Nice to hear it's on the road! Should look mad when it's done. Yeah, space is a premium and lots of storage boxes are my friend. Gonna get block cleaned crack tested and bored, honed then build it up myself. Clearances and keeping it all spotless is what it's all about . I'll take my time doing this build and have to save more dough up!

Hey Sinful, Nice to know that your engine is fresh aye Yeah, the r33 N1s were great for a bush bearing turbo and when I first got the car it put out 296RWKW on 18PSI. Put the 2530's on and at first they were a little slower to come on, but with poncams and tune it is a great street car. Very sensitive to cam timing these 26 engines are!. The 2530's make the same power with less boost. When this engine is done we'll see what the response and drivability is like, I can't wait.

Cheers R. Yeah the gear outside diameter is bigger too as well as wider. Here's some pics of the main and bigend bearings. Mains are Green (standard 5 bearings).

Pic of oil pump disassembled. Screws were locktited. Oil pump on the right is from the engine (r33 95 model). Oil pump on the left is an old N1? pump I had lying around. It has slightly wider gears, less teeth and a different internal design and more screws for cover. Gonna see how much billet gears will cost to get made just for curiosity sake. A new pump will be used either way.

Thought that the 2530's were good for around 400kwish at a stretch? They are rated around 320-350hp each.

Check out spool rods $645 all up I'm seriously thinking about getting them instead of prepping stockies.

Mum has one,manual. They have tall gearing to improve fuel ecomony in the manuals, kills acceleration. I thought the excel she had befored was a better car/shopping trolley, but getz has more goodies.

True lol. Amazed it ran ok for so long! Pulling out oil squirters, the bolts have a valve and spring inside and seem to only open when engine oil pressure is high enough!!Mad engineering. Block is bare now, cleaned it and wrapped in gladwrap ready for machining. 86.5mm should clean it up nicely. Checked the crank and bearings for damage/wear and thrust and all seems to be great for the use and abuse it had/has taken. Measured mains and big end journals, big ends are all the same measurement. No out of round issues either. Now I have to choose between ACL race series bearings, or Nissan bearings. I compared an ACL to a nissan shell and they look almost identical. I'll put it down to what I can get easier. I've heard and been told the ACL's work well. The R32 and R33 GTR engines have a few differences in regards to colour coding on bearings, as I have the R32 workshop manual. Just going off the markings on shells. Crank is a long pump drive(r33) and oil pump is good. The crank cam gear keyway will need to be welded and machined as it's stuffed.

#3 #4 #5 #6 Last pics are of #6 piston.

Hmm, true that one. I want lighter but stronger internals.. Cheers for your input Just pulled off everything except for crank and cradle. Not too happy with what I found with cylinders 4, 5 and especially #6 piston. It was doing great to still be running ok. They look like something has been in there judging by the score marks and pitting/chips on pistons. Pistons have no busted ring lands and no broken rings Reading the engine failure thread ages ago, I'll assume in it's last home it blew a rear stock ceramic turbo and sucked in some crap... Maybe. When I bought the car it had R33 N1's since it was imported, now running 2530's. Engine is complete stock internals, 86mm bore so I will get it taken out to 86.5MM (20 thou over). scoring is around 8 thou deep on worst areas. Bearings are in good nick, no picking up or scoring, they were stock nissan too. Crank big end journals were smooth and no scoring. I'll pull the crank out tomorrow. Anyway here's the pics: My work space...just one carport is mine![ tta hment=168899:head_yo.JPG] #1 #2
