Gtr Nismo #283

[Bern]

check what block you have! I'd love to find out...

[EtienneGignac]

Hey Bern how's it going ?

05U standard block.

Maybe the first owner got scammed ??

[Bern]

good man...got myself an Audi A4 from a dealer auction...lol

anyway, I don't think there was any scamming involved as Nismo's never came with N1 blocks

[EtienneGignac]

Craptastic !

Hey.

Finished putting the engine back in a couple of days ago. Engine cranks but doesn't want to start.

Check fuel, good. Check ignition, good. So what's missing ?? Air...Check compression: nothing. All cylinders under 50 psi.

I guess the engine is coming back out again. We'll see if it's easier the second time...

That Rb30 is getting more and more appealing...

[EtienneGignac]

**** **** **** **** damn **** god crap **** !

Little update.

Pulled the head today, look what I found on #4:



close up:



Is that a typical detonation sign ? As you can see #3 (on top) also shows some signs of whatever happened.

The head at #4:



What do you think ? I'll also post in the tech section.

[EtienneGignac]

So what do you think guys : rebuild the rb26 or go with a rb30 ?

The car has only been bad news lately....I need someone to cheer me up.

[Joker]

I'd say unless you are hella patient and/or hella rich, stick with the RB26. Have you read what money can buy yet? 8-)

Yeah I was more thinking of something like 1000$ for the shortblock, 1000$ for the adapter and put my head on it. Done. Let's say 3000$ max. Not 385 billions like felix.

[EtienneGignac]

Smalll update for whoever cares...

Engine is now at the machine shop for an overbore.

More to follow...

You should have your pistons before the block is machined.

You should have your pistons before the block is machined.

To match piston size with bore size ? What to use for piston clearance ? Same as the one for the cast pistons ?

Edit: According to manual, stock piston clearance is 0.035 to 0.055 mm or 0.0014 to 0.0022".

[tokes]

Yes, to match it up with the bore sizes.

I can't remember off hand what the clearance is on my Wiseco's, but since they are forged it is larger than stock. There are also manufacturing variances in pistons. Your set of 86.5mm pistons can have a few thousands variance in them, so it's nice to have them on hand to match up each piston to the bore it's going in.

[EtienneGignac]

Makes sense.

Anyway the block is in for a hot tank followed by a magnaflux (see beginning of this thread for oil-in-prestone situation). It's not gonna be bored before another couple of weeks.

I'll buy the pistons if it checks all good. If not, well, I don't know what I'm gonna do. Start to prostitute myself maybe...:sick2:

Does wiseco provide the clearance with their pistons ?

Oh and my pistons are ordered by the way.

[tokes]

yeah wiseco includes a sheet with all your recommended clearances and ring gaps on there.

You were just talking about getting an N1 or an RRR block a few months ago, so a basic stock block buildup should be within your means financially :P
