Hey guys, i've created an rb26 saving account where i put my money into where i can to save up for the cost of a full rebuild for my motor, car is old now and theres a possibility it mite be on its way out, so im just being prepared thats all....

I've decided i would like to run the car primariliy for the street, hill climbs occasionally on street roads, and track maybe once a year(if that).

I'm after reliablilty more than power, an 11sec gtr street car would be nice:)....and want heaps of response out of the car

Here's the plan of attack, please feel free to share some ideas, and give advice on parts i could do with/without for my goal of ~300-320awkw max.

My car is a 95 r33 gtr vspec.

Parts List:

Standard Rb26 Head + Block - bored to 86.5mm for oversized pistons (is an n1 block worth buying if im aiming for this power goal and reliability)

Tomei 9.15mm Lift In and Ex cams + Tomei adjustable cam gears.

Tomei Headgakset Kit 1.2mm thick 87mm Bore, including the Oil restrictor fitted to Head.

N1 Oil Pump

Replace Water Pump with Brand New factory item

ACL Race Big End and Main Bearings

Stock Rods + ARP Rod Bolts

Forged Pistons (dont know which brand? maybe Tomei, JE, Wiseco?) - need help here - .5mm oversize

Arp Headstuds (which i already have in engine - which can be reused right?)

HeadWork - dont know if its worth replacing all valve guides, retainers etc...can it get quite costly if i do???, and would you reccommend it?

Sydney Kids Oil Mods (all of them)

Dont know if i should get bigger Sump?

HKS GT-SS Turbos or maybe R34 N1's

Nismo 550cc injectors sufficient?

Apexi Power FC D-Jetro

Bigger Intercooler?

Tomei/HKS Dump Pipes

Bosch 040 Intank Fuel Pump

Is there anything else ive missed, or things i dont really need for my power goal in mind that can save me on costs, id like to keep it as low as possible.

I was told my head is now on its last stretch, and shouldnt be machined again, so ill definitely be buying a new head, maybe a block aswell, so i can get the whole motor put together and dummy tested etc while mine is still running.

Let me get some advice please, this will be my first big rebuild, i already have 10k.

list looks decent except you should upgrade the rods also while its apart, Go with the GT SS turbo's for awesome response and yeah you should look at a modded sump also to prevent oil surge.

It pays to fully rebuild the head with new guides and so forth, as for who, get a list of recommended shops in your area and go visit them, ask them plenty of questions but make sure they have delt with RB's before.

10K will cover the build up for the motor, the turbo's and bolts on will chew up a fair wack more :)

Thanks simon, i wish i was in AUS< as there are so many reputeable workshops over there, im in NZ, and theres a really good rb workshop local, who ive gone to in the past as they know the rb engine so well, all other garages generally point me to them as well as they do have the know how on the cars....

How much for a full head recon anyhow???, and is an n1 block a bit too overkill for my power goal in mind?, how much should i expect to pay for an rb26dett head and block?

Thanks, ill purchase some eagle rods for the car aswell, i hear ou can get 2 types, like h beams or something?....whats the difference?

Also, im buying all the gear myself, and then handing it over to the workshop to put together, much cheaper this way for me. What am i looking at spending for a full head recondition, and ca oyu mod the stock sump, or could i buy a new one?.....i hear bigger sump means a bigger restrictor in the head gallery aswell?

Certainly no need for the N1 block

Stock block is no problem.

stock cooler - more than adequate

sump - wouldnt bother really for 300-330rwkw (GT-SS range)

Other than that your parts list and plan looks spot on.

It will each up your money perfectly :D

Thanks mate - yeah i had a long thought about it, and it seems i'd have to spend roughly that amount to get it reliable and safe and the way i want. Any good deals i should know about for any of the above mentioned parts?.....my main concern is what to do with the new head ill be buying, should i give it a full recon or not?

Good plan, i like :D

A non N1 block will do fine, but 86+mm doesn't leave much meat between the bores no? Try and get away with the min boring required (common lowest dominator cyl)

New guides, springs, retainers and a port match to your manifolds and plenum is worth it imo. Actual heat work not so much.

If you ain't seriousally tracking it, a sump isn't needed. Just do the overfill thang.

Use a Autronic or Haltech if you have any remote interest in "showing" the $ u spent on the motor... (dunget me wrong, PFC will do the job)

Stock IC is fine.

Teh issue is, if you do decide to lean on it a little.. track work etc... then you'd want some sump tricks and some surge tank bits. 10K is already enough hey :(

EDIT: damm i shoulda F5'd before posting. You could def get away with no headwork... but i reckon if you going to spend the dooolers, do the head right in case you wanna bigger turbs / cam setup later... likely if you ever want that brutal pull.

How much to buy new guides/springs and retainers roughly?.....i wont be taking it on the track much, but hill climbs are something i may do....Well i just want to bore enough to fit oversized pistons(.5mm oversize)....so like you said the least amount necessary..whats the overfill thang you say to do in regards to the oil mods???, and also, how much could this motor rev to safely?

thanks....

    • I don't. I mean, mine's not a GTR, but it is a 32 with a lot of GTR stuff on it. But regardless, I typically buy from local suppliers. Getting stuff from Japan is seldom worth the pain. Buying from RHDJapan usually ends up in the final total of your basket being about double what you thought it would be, after all the bullshit fees and such are added on.
    • The hydrocarbon component of E10 can be shittier, and is in fact, shittier, than that used in normal 91RON fuel. That's because the octane boost provided by the ethanol allows them to use stuff that doesn't make the grade without the help. The 1c/L saving typically available on E10 is going to be massively overridden by the increased consumption caused by the ethanol and the crappier HC (ie the HCs will be less dense, meaning that there will definitely be less energy per unit volume than for more dense HCs). That is one of the reasons why P98 will return better fuel consumption than 91 does, even with the ignition timing completely fixed. There is more energy per unit volume because the HCs used in 98 are higher density than in the lawnmower fuel.
    • No, I'd suggest that that is the checklist for pneumatic/hydraulic adjustable systems. I would say, based on my years of reading and complying with Australian Standards and similar regulations, that the narrow interpretation of Clause 3.2 b would be the preferred/expected/intended one, by the author, and those using the standard. Wishful thinking need not apply.
    • Yes they do. For some maybe. But for those used the most by abusers, ie Skylines, the numbers are known. The stock eyebrow height for R32/3 Skylines is about 365/375mm or thereabouts. The minimum such heights are recorded in adjacent columns in the database.
    • Hmmm, interesting. Makes me wonder whether there is bias as well. It's the cheapest fuel, so it is used for all kinds of ill-maintained shitboxes which are bound to have issues regardless. Nicer cars tend to require higher octane rated fuel and can't use it anyway. FWIW, the official NSW E10 facts page is decent.
