Engine Rebuild

[PhilGTR]

hey guys,

I was just wondering what would be involved in an engine rebuild for an rb26? Like what parts would be invloved? B)

[StageZilla]

hey mate depends on your budget, power target. u could just get a set of bearings and rings and a gasket set and bolt it together stock, or for extra safety and power u will be best with....

forged pistons, treated gtr rods or even forged rods for safety, new piston rings, new bearings, all new oil seals on crank and cams, new block core plugs, full gasket kit is also needed. aftermarket oil pump (JUN, or so) for more power, and also a larger baffled sump is a must on any gtr with decent. then the rest of the gear u can either reuse or buy new better aftermarket stuff, like cams, crank, etc etc.

i've recently posted a thread with detailed pics of my rb26 rebuild in the Forced Induction section, its called "jun 2.7L engine build" or something like that, plenty of pics to see whats going on

cheers

A standard rebuild is generally just:

Take out of car and disassemble

Clean and crack test (and maybe xray) block, rods, crank, pistons.

Hore (light) or Bore (heavy) the bore of the block to match pistons

Clean it again

Measure and machine (if necessary) crank

Pressure test head to make sure it seals. Replace valve guides and seats if necessary

New Welsh Plugs

New Big end and main bearings

New Rod Bolts

New Rings

New Oil Pump

New Water Pump if necessary

New Rear oil seal

New Gaskets including head gasket

Put it all back together and back in the car

Often people decide to go bigger or forged pistons at the same time since they cost about 1500 and the rest of the job is $6k+, might as well do it when it is all out. Rods, Crank etc etc at the same time depending on how much you want to spend

So you'd be looking at close to $8k+ for a "complete" rebuild.. ouch..

around that figure

Yeah I did it a fair bit cheaper but I did all the work except for machining myself. Was still over $2k and say 60 hours of labour including work, deliveries, research, costing etc

And of course my motor only lasted 2000klm until it spun a bearing again so I need to do it all again and have another look at what I got wrong.

You can keep it cheaper using aftermarket bearings (ACL or King are about 1/3 of nissan), make sure you get a full VRS (Gasket and seal kit), RB30 water pump is dirt cheap, standard oil pump, all up would save you a say 500-800. As would getting access to parts at trade price.

Duncan you are a cheapscape mate , you dont get much for $2k .

As for your spun big and bearing , i would say it was your machine shop , who ever did your crank but you should have checked it when you assemle it to make sure the clearances were correct . I'm you will do that the second time around , like double check this time .

If you need a good crank place p.m. and i'll give you his details.

PhilGTR, a good engine builder will checl everything when the engine is disassembledand replace evetything that is worn .

Always rebor, hone and deck the block , new pistons to suit ( with rings ), check crank , new bearings, ( big end + mains )new oil pump + water pump , new gaskets and seals and service cil head and new timing belt , tensioner and iddler .

Thats a very basic rebuilt fo any engine and by the time you pay for R+R at least $7-8 k for a good job .

[Duncan]

hahah yes I do need a good machine shop, I'll give you shout once I get my act together And yep, I will double check next time, the funny thing is the stuff I got the experts to do is the stuff that went wrong

horsepowerinabox sell pre done rebuilds for rb26's for $5500. All you have to do is bolt on your head and drop it back into the car. They use forged pistons too.

stay well away from venolia forged pistons i've heard (they sell em in the High octane shop in a full rebuild kit for $5000 with rods, gaskets. etc)

lots of bad reports on them, but i hear High octane offer other brands now because of the issues.

Thanks guys,

I hope i dont need a rebuild soon. I think I just need to get some new coil packs and spark plugs for mine. Are the Splitfire ignition coils any good?? I seen them for sale around $490ish from perfectrun.com.au.

I saw a rb26 rebuild kit at high octane for $3860 with CP forged pistons. So from what you guys are saying, thats only part of the kit?

[RNGTR]

Only advice I can give is dont skimp on anything.....

[gdogzgtr]

I am currently getting engine rebuild and have only paid for parts and it has cost 2K for forged pistons and 2500 for upgraded oil pump, blue print, water pump, N1 bearings, timing belt, metal head gasket and new crank. I am looking at trying to get about 330 awkw and was informed that all pretty much a must. Only things left would be oil sump, oil cooler and upgraded cams. Passed up on them as not necessary for daily driving. Good luck with it all and as I was told do it once do it right otherwise it will cost you more time and more money in the long run.

Phil shoot me a line if you want some advice with it as I've been through it all before

My friend and I have just spent the last month striping and prepping an rb26 to fit in to a VL and he blew 6 grand on the short block. But it is built for around 800-900Hp. cp pistons, Jun rods, machined crank collar and N1 pumps etc.

And that was with us building it. So if you are getting someone else to build it I would put aside 9 grand for a strong engine.

Cheers,
