...sorry for the small highjack.i had a rb26 in stock form it made 267rwkw then the turbo broke and bypassed the head and found a new home on my piston's and started main course on my sleeves.to make 350kw on it i would say turbo,exhaust mani,wastegate,gasket and arp bolts on the head and you will have to sort out a aftermarket oil pump to keep that hungry head happy.so all and all rb26 is king but to expensive to build.for that reason a 25 is a better option.but hey that's just my 2cents..back to the topic at hand.congrats with your build!many many happy miles!

I notice i say 267 RWKW, that should be well over 300kw(flywheel) what boost did u run the turbo's? injector size?

Stock injectors,1.4bar.no meth nothing.i was stupid to push those turbo's so hard but its school fees.no point crying over spilled milk or turbo's in this case.

Yes, its well proven they dont last long over 1 bar, think u might have maxed out the injectors too. 1.4 bar on ceramic turbo's, pump feul on 440cc injectors........ wont last long

tiny tiny update

my gear lever was really really loose due to a worn bush going tino the gear box from the lever.
changed it with a nissan v6 bakkie bush (same size) and WOW all i can say is it made a world of difference. now i can really feel all the RB goodness, what an awesome gearbox, so precise and close, love it

really happy with how its running

Glad u got it sorted. a small part can sometimes make a huge differance.

ya, that little part made the HUGEST difference in the whole feel of the car, so much better

the RB gearbox is really really nice, couldnt feel it properly at all before.

the bush i removed was about 1 third of the size of the new one, it was almost at the point of being so worn that it would just fall of

basically wasnt even doing anything.

all sorted now tho

good some new (used) goodies a couple days ago

needed wheels ever since i did the engine swop and came across these which are the exact style i wanted just not the right width, they 7j, so gona get the rears widened to 9j to take some 255's, got the wheels at a good price, so all in all with widening etc will work out alot cheaper then getting a set of wheels imported and so on.

here they are:

also got an oil temp, oil pressure and boost gauge to help monitor my rb's health and running

when i get some time later next week i'l install the gauges, not sure if i wana dash mount or pillar mount or what yet, then gona send the rear wheels to hi tech mag repairs for widening on monday (unless anyone knows of a cheaper place)

will post better pics when they on the car

new goodies are always so exciting

p.s after these upgrades next is z32 brakes all round and coilovers(not sure on which ones yet)
