Mark And Duncans R32 Build

[Risking]

Sounds Like Hard Work

BTW Risking - Isnt it a CAMS requirement to have the Oil System Isolated from the cabin?

There is no such ruling that I was made aware of nor have been able to find. It only states that leakage into the cabin must not be possible.

2.5 All oil storage tanks situated outside the main structure of the car must be surrounded by 10mm thick crushable structure. In any case, no oil storage tank, not located within the main structure, may be situated aft of the gearbox or final drive casing.

2.4 Except if the cables, lines and electrical equipment such as battery, fuel pump etc, are in compliance with the requirements of the aircraft industry as regards their location, material and connections, they must be placed or fitted in such a way that any leakage cannot result in:

• accumulation of liquid;

• entry of liquid into the cockpit;

Should the cables, lines or electrical equipment pass through or be fitted in the cockpit, they must be fully enclosed in a cover of a liquid-tight and fireproof material. No oil, fuel or electrical lines shall be situated beyond 600mm on either side of the car’s centreline and must not run adjacent to the main fuel cells or within the crushable structure.

2.5 All oil storage

My tank is fully sealed inside the cabin ( ill put up a current photo latter) and my breather runs out the OSR inner guard via a filter. All my lines which run inside the car are in accordance to the 600mm rule. I did get knocked back on this the first time it was looked at.

According to the rules unless you have a fully sealed rear fire wall OR have all breathers exiting to the outside most dry sumps I see floating around are infact not in accordance to the rules.

Back to my on a budget..... or something like that engine build.

Talk about bearings

Main bearings i'll start with..

i pulled out the crank lastnite of my N1 motor. all the bearings look pretty good for someone who has no idea how they are ment to look. all were Nismo items and i noticed the numbers on the bearings changes alot.

when buying new bearings say acl for example, i can only see two part numbers. standard and oversize.

but nismo offer around 6-7 different grades

whats the score here? do i go with acl? and how do i know which to buy? i take it i will need to get out the verniers and measure the crank in each place?

should i leave this up to the engine builder?

[Duncan]

nothing wrong with the ACL gear we have been running it for years. and its the right price.

And, despite my history, I would definately leave it to the engine builder - give them the block and the crank and ask them what size bearings after they've checked it out. then once you get the bearings check it all out with flexigauge.

acl have 2 sizes in big end, and 3 in mains

http://www.aclperformance.com.au/NissanRB26DETT.htm

Plus their "extra" size which is 0.025mm over standard for a little more oil than normal on a standard crank.

[haw001]

Duncan, aren't the "extra" .025mm UNDER standard for more oil?

[haw001]

Measuring bearing sizes is not that hard with the right set of feelers, but, and this is a big but, you could get away with it if you kept track of each bearing placement on removal or if they were all the same. If none were really damaged, and you could look them up from Nismo, then it would be very easy to match with and ACL version.

As long as you crank came with your block, then it's been tunnel bored and shouldn't need much more than a good clean with some wet sandpaper.

Of course, if you've got an engine builder doing all the assembly, it's all pretty pointless as any decent builder you're paying money to will check everything first and tell you which bearings to buy.

[Duncan]

yeah yeah under not over for bearings. technicalities.

I wanna see pics of your car getting crushed goddamnit

[Neil]

I wanna see pics of your car getting crushed goddamnit

shit we should have taken pics of it on the trailer,,,or did you take some Duncan???.

Crushing pics,,,are you in one of your nasty moods again,,,.

[Duncan]

lol yes.

no i wish i did but i didn't would love to see the rest of it getting made into a coffee table but I missed that too. at least the damn thing won't draw our blood again (except maybe that glass left on the grass)

[Angus Smart]

Yeeerp i kept note of where every thing came out of all numbered etc etc. tho some of the nismo numbers are no longer listed on their website or in any web stores..

i might give it another search around for the numbers and see what i can come up with. tho i guess i may aswell just let him buy them as they are not that expensive.

[haw001]

No pics, I couldn't take them through the tears. Actually it was all over so quick I didn't get a chance. The cage may have survived the roll down the hill, but the massive jaws of the crusher made mince meat of it in seconds!

[haw001]

Just get him to order the acl race series. They are cheap, about $150 for both sets.

[Angus Smart]

what happened to this car??

yeah acl are good price, ebay usa and stores for around 100 usd. but 150 sounds better.

[GTRsean]

what happened to this car??

yeah acl are good price, ebay usa and stores for around 100 usd. but 150 sounds better.

Got my ACL race series (no discount price) $260 from Rocket industries. Mains and big end bearings.

I'm sure you can get em cheaper, but thats what I paid.

[Angus Smart]

Your item is being processed by customs in AUSTRALIA. Sweet pistons and rods will be here tomorrow or thursday, usps says the 3rd but this could mean america's dates.

i will get onto the bearing thing soon. there wasnt any known problems with acl bearings? old stocks? etc etc?

[Neil]

what happened to this car??

Massive roll-down a hill at targa tassie 2007,,,the cars finally gone to GTR heaven and Marky's wife can now breath a sigh of relief.

I'm sure pics will be forth coming,,,nothing like taking the piss,,,I have them but crappy SAU can't resize them.

Looks like you two are on your own this coming weekend,,,I have to put my rear end back in and get ready for oran park the sunday after.

Love as always

Neil.

[Beer Baron]

so what are you going to do with the cube that was the old car? po mo art? lol.

[GTRsean]

The ones I got were 2 months old by the date stamped in the shells.......

[Risking]

Andrew dont go and buy any aftermarket bearings without grinding the crank to suit them.

Factory bearings are graded so you can get the correct clearance without the need to grind the crank. You just select different bearing grades to suit any irregularities in the crank or tunnel.

Aftermarket bearings like the acl's should have the crank ground to suit them not just thrown in.

I would normally grind the crank so its a tight clearance and I know it will need more, mic up the crank and tunnels, flexi guage the clearances to confirm my measurements, then work out what needs to come off each journal before re-grinding the crank to the exact clearance.

Its time consuming but rewarding when you know each clearance its right.

Alot of people will take the 10thou off the crank, flexi-guage it (not knowing how to do it properly or accuratly) then assemble it with whatever clearance the crank happened to be ground at.

Thats just the way my machinist has taught me to do performance engines and it works for me.

Another vital is to check the crank is straight. You'd be suprised how bent yours may well be even though the engine was a runner and in good condition.

Dont touch it with wet/dry or any sandpaper.

If your going to measure it up use a micrometer, vernier callipers are not accurate enough to calculate bearing clearances if you decide to do it this way. If you need a set of internal mics your welcome to borrow mine.

[BezerkR32]

all the bearing sizes are stamped on the front of the crank. there is a chart you get from nissan and you use it with the numbers stamped on the crank to disipher bearing size. after market bearings are all the same size. crank grinding or linishing is a must when using them. micking the crank and then the tunnel is much more accurate than plastiguage also.

Yeeerp i kept note of where every thing came out of all numbered etc etc. tho some of the nismo numbers are no longer listed on their website or in any web stores..

[Angus Smart]

I've been looking at that guide in the nissan manual, which has led me to ask these questions as i figured from what i read there are many different combinations needed. as the numbers/letters vairy on the crank and on the block.

its going to be a job left up to my engine builder

and i ordered all my Arp parts.. but nothing has come off the cc, or there is no contact in america from the guys. they are in what i can figure out Minneapolis. i dont think thats anywhere down south where all the problems just were..
