Well just got a quote for my rebuild (RB25DET), was wondering if you could all look through it and give me ideas on what is priced good what not. and altertnatives?

ACL Mahl Forged Pistons with rings(20thou). $1400

Tomie metal Headgasket................................$550

Nissan Gaskets..............................................$200

Bearing Set (Tri-Metal)....................................$300

Welsh Plugs....................................................$80

Machining, close & hone, shot peen ..............$2000

Rod Bolts........................................................$280

Head Bolts......................................................$200

Labour charge

28 hours........... $2150

Totalling... $7290

Also i am only planning on getting 250rwkw out of the motor... so the stock rods should be up to the task?

Is this about right? anything i should change? any ideas where i can get parts for cheaper from... ?

Thanx in advance

you probably don't need to spend that much on a headgasket... imo

and you could probably save a couple of hundred on the pistons by going Arias or Venolia

stock rods will be fine for 250rwkw

other than that it sounds about right, good luck with it

btw what happened to the old engine?

Don't skimp on the bearings.

 

Either go Nissan or a set of King HP Bi-metal bearings or Clevites.

 

What brand are they?

KING HP rigns a belll, not 100% sure, but will double check...

Also i was thinking, no need to go for metal head gasket as i wont be pushing that much power, to really need one?

Rebuilder told me vernolia pistons are abit thin or sumtin, and doesnt like them?

But alot of people seem to be running Arias with no problems, can anyone give me a price on arias 20thou over?

Turbo seals went, oil went to the intake in the engine detonated...

$2000 for machining ? a bit on the rich side i thought , then again depends on what they are going to do .

Does that include cil head work and crank regrinding , for that price it should and its still high .

I had arias pistons in my rb26 40 thou oversize no probs , trade price around 1000 - 1100 including rings .

Machining including head work needing to be done... valves need to be reset...

The quote was from MRC

$7000, if that includes motor in and out of the car.

Then thats a fair price, i paid a similar figure for mine which is very reasonable.

including

Arias pistons,

GTR Rods - which i reccomend you factor in as they are cheap as, and you'll have a tough bottom end then indeed. With room to go for more power later

and all the other stuff :P

If thats what he said, its time to go and find another engine rebuilder that actually knows RB motors.

Its to much money to risk IMO

You do not need to use a GTR crank to run GTR Rods.

My RB25 uses GTR Rods with stock 25 crank.

You run the GTR crank it makes it like 2.6 or 2.7 ltr, cant remember which.

Rb 25 is the same bore as rb26 , the diff is the stroke 71.7 mm for rb 25 ( 2498 cc) and 73.7 for rb 26 (2568 cc ) 20thou over (.5 mm ) will give you extra 30cc aprox .

You have to make sure they know what pistons to use as well to retain your compression ratio of 9 to 1 . Unless you want to change that but make sure you know what you are getting dont relay on them .

rocketindustries.com.au was where I got my pistons... (great price and service)

cams from nengun.com (great price but delivery was very delayed)

everything else, water pump, bearings, timing belt, gaskets etc was all from Nissan but I can't remeber which one... I think it was Blackburn

      Stagea Front CV Axle Question

      By dbm7 · Posted

      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

      Stagea Front CV Axle Question

      By Duncan · Posted

      I don't know for sure, but I'd expect them all to be interchangeable given the diff end and hub end don't move/change between any C34 series. Often Nissan will change part numbers and the aftermarket follows those year ranges; but the original part number change doesn't mean other parts won't fit. The change could be a change in material, internal parts or even just supplier. For example, all the RB gearbox to engine bolts are no longer available and there is a new part number instead. The only change is they went from cadmium plated bolts to zinc plated due to the issues manufacturing with Cadmium. They look different but work the same.

      Stagea Front CV Axle Question

      By soviet_merlin · Posted

      One year is a bit concerning. Did you try contacting GSP? It says 5 year warranty on the box if I remember correctly. I'm also running their driveshafts on my S2 Stagea.   You could check the part numbers on Amayama for your year. Here's the link for my 1998 which gives the 39100-23U60 part number. Well, that and 39100-23U70. https://www.amayama.com/en/genuine-catalogs/epc/nissan-japan/stagea/wgnc34/6649-rb25det/trans/391 What does it say for yours?

      Stagea Front CV Axle Question

      By S1_C34 · Posted

      I ordered a GSP Front R/H Axle from here - https://justjap.com/products/gsp-premium-front-driveshaft-r-h-nissan-r32-r33-r34-skyline-gtr-stagea-4wd#description It lasted around a year before one of the boots blew out. I'm lowered, but I have GKTech roll center adjusters. One year seems a little premature. I think I'm going to spend the extra money on an OEM cv axle this time. This website - https://tfaspeed.com/collections/nissan-stagea-wgnc34-x-four-parts/products/nissan-stagea-awc34-260rs-rb26-right-front-axle-drive-assembly Makes it sound like the readily available OEM CV axle will only fit 11.1999 Stagea and up (mine is a 2.1997 S1). The JustJap listing didn't mention any years or anything for the GSP axle. Amayama shows '11.1999' and up as well for that part number. As well as 'plastic boot type'. See attached picture. So I guess my question is, does that axle (39100-23U60) really only fit S2 Stagea? It's the front driver side. If it does, I'd love to buy that instead of rolling the dice on another GSP. I've found that OEM one cheaper here: https://www.partsfornissans.com/oem-parts/nismo-jdm-r32-r33-r34-skyline-gtr-r32-gts4-right-front-axle-3910023u60 and here https://www.nissanparts.cc/oem-parts/nismo-shaft-ft-drive-3910023u60 Just a little confused because the JapSpeed listing for the GSP front driver axle doesn't mention any specific years or anything and it fit my S1 Stagea fine. So will 39100-23U60 fit my S1 Stagea even though technically it says '11.1999' and up? What would have changed? Thanks.

      CD009 RB Conversion

      Thanks for the info. The only "Issue" I've had with the shifter is I always found the throw between 4th and 6th gear too close. I'm always worried to shift into 4th accidently and sending my motor to the moon. Adam LZ recently came out with a video and stated Serialnine revised their shifters to correct this and will change all the revised parts for 150$. Strangely enough, I contacted Serialnine right after and they denied it and said it's bullshit. I found that strange as he's a distributer. I'll keep this forum post updated on that saga.
