mah Neo RB25 build

[slow40]

so bored today thought i'd throw up my progress on my garage project,
some of you've seen this on other forums, but thought i'd post it up for my fellow zilvians!

motor: R34 NEO RB25 stroked with 26 crank

i chose this motor thinking NEO's fixed the crank collar (found in the series 1 & 2) problem resulting in oil pump failure (WRONG! :smash: )
has RB26 Rods
Solid lifters
Newer motor
Pull type clutch..yada yada

on to the pics :bigok:

[slow40]

so this is where the fun began :bash: :bash: :bash:

went to reseal the oil pan and inspect the snout for the good oil drive and came up short

http://i110.photobucket.com/albums/n106/project89silvia/crankcollar011.jpg

gotta roll with the punches i guess :)

ended up finding a super deal on a rb26 crank with the long drive and jumped on it, new ARP fastners, ACL bearings, stock 26 rods.

http://i110.photobucket.com/albums/n106/project89silvia/crankcollar022.jpg

also some 26 CP pistons

"so i thought..."

BUM BUM BUUUUUM!!!!

the stress...its killing me.

seriously...its killing me:bash:

EDIT
....and then you posted. lol sucks about the stock crank, but at least your replacing it with nice parts:) should be a stout little engine once its shoehorned back in there.

[slow40]

lol, patience my friend

can't wait to upgrade this turd

and the money shot

http://i110.photobucket.com/albums/n106/project89silvia/OilRestrictor017.jpg

[slow40]

that's how she sits as of today...

still need my harness back (been waiting over 3 months!?>! wtf!)

got the trans mounts bolted in, driveshaft is in, exhaust is somewhat together.. need to mock up interfooler piping and radiator, fans, fuel pump/filter, wideband, relay for battery relocation, some more stuff i'm at a loss right now. will update when i can. any questions comments shoot!

[Xandy Boosts]

she's beautiful

that is a greedy manifold I bet :rofl:

[SR20d2fourT]

Dang. I'm jealous. Trade me for my rebuilt KA w/ 5k on it. hahahaha, yeah okay. Awesome progress. Nice paint too!

[slow40]

lol, thx guy

[S14DB]

What's the Head drain for?

[BoroDrifter]

I'm impressed! Looks great. I feel for you on the harness. I waited almost a year for a megasquirt harness I had being built. I had to write a letter to the BBB and the Missouri Attorney General. Only then, after legal involvement and a lot of stressful phone calls did I get it. Motherfucker still owes me an EDIS too...
Hope all goes well for you.

[slow40]

What's the Head drain for?



supposed to help "trapped" oil in the head return down to the sump faster.
rb's have a problem with excess oil in the head during sustained high rpms.
their's a fitting that's probably more effective, but i just worked with summit for the 90. kinda wished i waited for something cleaner like this
http://i110.photobucket.com/albums/n106/project89silvia/rear_oil_drain.gif

just pop out the upper freeze plug and stick it over

thx man, just curious who did you harness??

[debby]

wow, great project, can't wait to see what's going next!!!!

[slow40]

thx debby!!!!

[McRussellPants]

Those drains don't really work to well imo.

We did it on the Z and it didn't really help. Two 10ANs from each Valve Cover to the pan and there was no change in oil pressure drop through the corners.

did your z have an rb? also did it have an upgraded oil pump?
it's pretty common amongst the guys on SAU.
it helps to take additional steps to help the oil return back to the pan.


1.Block off one oil feed in the block (RB26’s have this standard)
2.Fit an appropriately sized restrictor to the other feed. The size of the oil pump is one of the determinates for the size of the restrictor, ie; a high flow, high pressure pump needs a smaller restrictor. Constant higher RPM needs a smaller restrictor etc.
3. Fit an external oil return from the rear of the cylinder head to the sump
4. Drill out the oil return galleries in the head and block
5. Machine around the oil return galleries to facilitate access for the oil

i've done 2 & 3 :-/
may be overkill but doesn't hurt

[02BRB20]

wow, lots and lots of duckets

[rican_nick]

nice build man.

[driftstyre]

great swap, really clean too. I didn't know you could fit the R33 crossmember right on there. Cool.

[slow40]

^ yep, uses same bolt pattern

[turtle m3th]

Oh hell yeah! keep em' coming man...

[slow40]

i'm trying man,lol

should be able to fire her up when my harness returns :hyper:

[s13coupedrfter]

Love the build, can't wait to see this car in action.

[BoroDrifter]

thx man, just curious who did you harness??

Um...Mark Gearhart? I had found him on Club4ag. He worked out of some shop in Florida as a freelancer. His specialty was Megasquirt n spark with EDIS for 4AGE 20v Silver tops. He also was known for swapping SR20's into AE86's.
What I got from him was damn good work. He just played games with me for almost a year and shorted me $150 worth of stuff. All together everything was just shy of $1000
I sent him a full stock AE86 wire harness (new)
All my 20 valve sensor clips
My Megasquirt n spark to program
My stimboard in case he needed it
Money for harness build, MS programming and testing and a complete EDIS 4 system.
After months and month and months of nothing and playing phone tag run around bullshit, I got my MS back and nothing else. And it wasn't even programmed!
Then a few months later I got my harness. The EDIS was shipped but never got to me and I guess he didn't insure it. So I lost $125 in the end.

It took so long for him to do the work I had to sell the car and write a contract stating I would hand over the harness and MS when it was all there. Pain in my ass... :smash:

[slow40]

damn man, what a hassle. least it worked out...somewhat

think i'll be getting mine here soon, just got word today that he's taping it up!

[BoroDrifter]

damn man, what a hassle. least it worked out...somewhat

think i'll be getting mine here soon, just got word today that he's taping it up!is it the same guy?

[slow40]

nah, different guy...thankfully

[slow40]

just got word my harness is being shipped tomorrow



muhFUCKING WOOOOT!!
hell yes

[Yum-Yum]

ahh i have this motor, damn didnt know there was another company for clutches..your keeping the pull type?

[slow40]

yeah it's still pull type,
i had a shop rework the stock pressure plate to accept the somewhat "cheap" disk, just to get the car running. rated at 450 ft lbs.
soon as i up the boost i'll be replacing with an Exedy Hyper single.

[JRas]

is that original paint on the car? or a repaint?

sorry, I know I am supposed to be more amazed with the rb25 got side tracked.. it's just so shiny and perfect

nice 350z track wheels btw

hopefully that harness comes soon

[slow40]

i just washed it that day before i pulled the motor.

not sure man, to be honest with you..i thought so too
when i bought it, it looked stupid clean for original paint
but i looked for overspray, checked inner fenders, carfax came up good.
no wrecks, i'm 3rd owner.

they may have just waxed her real good???
although one of the mirrors is extra faded, almost a different red
:confused:

[Ameer]

Nice setup! You encourage me to get back in the game of nissans. Currently I have a old BMW to go to and from college. But my s13 was fully built and a big distraction. Update me on your swap when its finished. BTW, are you going to stick with the same turbo or upgrade?....peace

[jackjack]

i hate it......... no wait........ i love it :werd:

[origin_s135]

very nice, jesus makes me wantto trash my sr by just looking at your setup. lsdjakldjasld

[slow40]

thx guys

are you going to stick with the same turbo or upgrade?

still not 100% which turbo to go with yet, for now i'll break it in on the stocker, eventually pull a wad outta my ass for mani/turbo/inj

got my harness back, should have updates soon

[Neejay]

Any updates?

[undercoverdjay]

You'll love your RB. I'm in love with mine. Hell it sounds better than my Z32 TT.
Great job with the rebuild bro. Definitely

[240srhatch]

nice build man

[IIIXziuR]

Damn Straight 6 looks so mean. RB25 in S14 is the business.
Nice swappage dude, keep up the good work.

[slow40]

thanks guys

Damn Straight 6 looks so mean. RB25 in S14 is the business.

I would love to see a video

[I10cruiser]

subscribed! hahah good build worth the wait for the vid!

[BLKS13]

Grrr, Only 2 pages! I know your busy but C'mon! Nice work man!

[BOSS NGA]

nice swap man. I have a RB25 aswell its a verII I love that damn thing its so fun.

[CKAMC]

Ugh

25 Neo's are one of my favorites

cheaper than a good 26 and makes almost the same amount of power stock

nice build, hope to hear it running and maybe see how a base tune turns out

[slow40]

same here man, curious as to what i gained with the .1 litre, IM, 3" exhaust turbo back. hoping at least 300wheel at 10lbs.

[MELLO*SOS]

Nice build, can't wait to get my RB finished and dropped in..

What fans did you go with?

ps interesting your old rusty water pump was a RB20 pump (no slotted hole).. Wonder if nissan did that from the factory or someone just threw it on there.

GL with the rest of the project keep us updated.

[slow40]

i went with FAL 12 pushers, i wanted to run pullers but clearance wasn't as good as i'd hoped.

i think all rb water pumps are more/less the same iirc

[midnight zenki]

So w/ the 26 crank & rods what does your effective displacement sit at now? I would assume 2.6, yes?

[Harbe]

looks good but all that work and stock tubo

[slow40]

looks good but all that work and stock tubo

yep, already have a big snail, just saving up for supporting mods ATM.

So w/ the 26 crank & rods what does your effective displacement sit at now? I would assume 2.6, yes?

yeah the crank bumped me up to somewhere around 2568 cc's (2.6).

[Enlefo]

Freakin awesome man, mad props.

[TheTimanator]

looks nice. What part of TN are you in?

[slow40]

^^ northeast of nashville about 20 miles, in goodlettsville.
hey you should come join www.tennspeed.net (http://www.tennspeed.net)
lots of locals on there. i'm same username

Freakin awesome man, mad props.

awesome, you're on here over 2 years and first post is my build haha. nice


i'm ordering some injector grommets to compensate for the greddy manifold, since mine are the o-ring style. going to the dealer tomorrow, if i get them in by the weekend, i should be able to start her up hellmuthafuckinyea

[slow40]

http://i110.photobucket.com/albums/n106/project89silvia/yadayada078.jpg

[slow40]

[mr_240sx]

wow sweet build....car is coming along nicely!

[slow40]

thank you sir

[slow40]

o werd...
as promised here's the walkaround vid.

http://youtube.com/watch?v=T4FVSusJumg

i have a fuel leak in the video, ha caught it as i was shutting the hood...whew. new line is on.
catch can will be on soon. the ticking is from a bad valve seat due to Revolutionary Performance not setting the right clearances i believe.
don't think it'll damage anything, just annoying as fvck and i'm not getting 100% outta my cams. probably take it up there sometime this week.

i will say though, it's pretty responsive. i've put about 60 miles on it. it's so easy to get going even out of boost. fell in love with the car all over again
i wanna put the power fc on and start playing with it a little bit, hopefully eliminate what appears to be fuel cut and adjust some settings.
other than that, just glad to drive it again, been sitting since last august..

[slow40]

unfortunately i'm selling her already, due to some unexpected events :-/

[rockit181]

Wait I don't get it what just happened? Is this car legit?

[slow40]

this car is legit

[David Steele]

Just some advice when add tighter clamping studs to a block you get the engine block align honed. Otherwise you're going to be pulling your non abundant engine block out again in due time .

[whatbrokethistime]

car is sold.
