Rb26 Rebuild

[adam Foster]

im building a rb26 got my gtr

car has a aurtronic ecu and cdi

has garret -5 turbos

555cc injectors

im wanting to build a reliable hard reving gtr which doesnt spin bearings

wanting 300plus kw at the wheels maybe 350

has a os triple plate clutch

just after some help on mods to motor oil issues etc head work? cams? pistons rods needed.

maybe someone near newcastle to help or build

can the gearboxs handle it drive shafts etc

Have a good read of the 'oil surge', 'broken N1 oil pump' and 'breather' threads for alot of the info you need on oil controll issues.

At 350rwkw, dont get too caught up with internal modifications... Get the engine prepped and built by an experienced RB builder, keep everything stock exept a set of forged pistons, oil pump (and matching crank collar) and set of drop in cams. Everything else gets measured, machined, ballanced and prepared correctly.

Get the biggest sump extension you can find/afford, a good oil pump (nitto seem to be the best option for the money), enlarged oil return galleries, block restricters, mines style rocker baffles and an accusump (if your budget allows).

If your going to rev it 8k+ invest in a good crank ballancer.

Your going to need an external 044 at a minimum or larger, bigger injectors and I would invest in a duel entry fuel rail.

Two rb20det afm's are the same size as Z32's but they plug directly into the rb26 loom and have enough resolution for 400rwkw-

I broke my first GTR box (3rd gear) at around 380rwkw... That was with an R3C (os tripple) clutch- For 350rwkw I would sell the OS clutch and buy a Jim Berry full monty, it will help the gearbox last longer. The rest of the drive line will be fine.

Contact Paul from Red R Racing for engine building etc...

brilliant advise i second that....would throw in a power fc but

[T04GTR]

keep the autronic. i did.. arias/eagle piston and rod kit. nitto oil pump and a performance metalcraft sump. and a 33 crank. or crank collar. and assembled on the loose side of factory bearing clearance specs.

Thanks guys helps heaps is there someone up newcsatle way good with rb motors

[adam Foster]

are the n1 oil pumps no good

Yes, Red R Racing is who you want. Forget the N1 unless you like to gamble (ignore Nismoid ) and get a Nitto.

if you want this to be 'hard revving' you will need:

valve springs (singles ok, but doubles much better if you can afford them)

while your doing them get some baby cams to open the engine up a bit at high rpm and get the valve clearances set too (important if you want to spin it hard)

get a good balancer. N1 balancer is a minimum, ATS or Ross is better still

get the basic rods/pistons/bearings kit like t04GTR mentioned above, and get them weight balanced too

fit a small oil feed restrictor, 1.1mm if you are going to be revving it.

good oil pump is a wise idea too.

big sump too since you are going to rev it

with all that gear 9,000rpm should be a walk in the park.
