Rb26 Or Rb 30

[Dynamix]

yes. but 3.5 years ago when i built my motor, i wasnt thinking of that.. if im gonna do an external pump it gonna be a propper dry sump set up..

but now days i can make a pretty good wet sump. anyone got a s2 rb30 block etc etc??????? (with the factory idler hole tapped)

So buiild a dry sump setup will be fairly expensive though, as you'd know. What pump are you running on your built motor?

hey ive got till the end of 2010 till im licenced

Jesus, how did you manage that, you did a decent job whatever it was, well done

[Mohsen]

this is that patrol engine

i think it would go very nicley in a 1 ton hilux

Exatcly.. or build it tough enough to take it. But remember you are doing this to a stock internal rb26dett with about 1/3rd more power than facotry, its days are going to be numbered ever quicker with a rev limitng driving style..

All depends how much power you'e chaising too, preped stock rods, forged pistons, acl bearings, greedy oil pump (either r33 crank or collar the r32 crank) balance every part in the rotating mass, get someone who's good at bolting it all together and you have a 400kw motor no problems. No as dear as some would make out to be and 400kw is nothing to sneeze at..

im doing an engine like that now...Red R Racing prepped stock rods, ARP rod bolts, ACL race pistons, ACL race bearings, Nitto oil pump and collar, Red R Racing 9 litre sump, Tomei oil restrictor, Ross balancer, N1 water pump, Red R Racing prepped and ported head, 260 deg 9.15 camshafts, New Nissan head and main bolts, MLS 1.2mm Head gasket and a full Nissan gasket set. Its based on my old 10.3 drag engine but will be used for circuit work...should make 400+kw on its ear and be ultra reliable. $15K turn key...not too bad considering my old drag engine if copied would work out around $2K to $3K cheaper as it didn't have some of the goodies listed and made 450AWKW all day.

RB28 FTW!

These days its easy(er) to make power pretty cheap, you could even throw in a set of rods for around 700 that come with arp bolts and it wouldn't hurt the wallet to much at all. You could even get away with doing things cheaper if you decided to use an N1 oil pump, stock balancer, stock water pump ect, but I wouldn't suggest or go with it either.

On a side note Paul, when you say turn key, what does that *really* mean as it can be left open to inturperitation..

Also as you mentioned, whats the plans with the RB30 you're thinking of building?

What kind of build you recomend for an every day street car, no circut work and no draging?

only looking at the bottom end ofcourse.

ACL pistons and bearings, Nissan main bolts, ARP rod bolts, Resized conrods, N1 oil and water pumps, prepped block (bored decked honed etc), polished crankshaft, crank collar, new idler and tensioner and fully balanced bottom end.

RB28 FTW!

Now that i think about it.. Rb28 was the diesel motor i was thinking about.. it came in the R31 GT-D and has a twin cam head..

has anyone ever done anything with that motor? a diesel motor would be considerably stronger you'd think!

its an RD angus. The D designates deisel obviously. And it has a sohc. I did 750 thou on one. great engine.

Apparently it can take the twin cam head with some minor mods and is a bombproof engine with cylinder walls way thicker than the usual rb to withstand the high compression of the diesel.

I believe the Rb crank drops straight in as well. Definte potential.

Concept... wonder what that would make the capacity..

are the blocks easy to pick up??

I'll let you know later today. Back a few years ago when mine finally died we searched the country for a running replacement and couldnt find one.

A rebuildable stuffed jobbie may be a different proposition tho.

Jesus, how did you manage that, you did a decent job whatever it was, well done

yeah, not one of my brightest days. reffer to my sig and im sure you get the picture

[T04GTR]

yes. but ripps or anyone that revvs there rb30 past 8k still hASnt told me how the oil pumps stays alive.. or what oil pump they are using...

oh.. i built mine with a jun pump.

[R31Nismoid]

Its probably the billet gear/caps etc in it holding it together perhaps rather than prepping the crank

Robbie uses std main caps in his race engine.

[N1GTR]

Dave, rips has said on video (correct me if im wrong please Rob) that their motors use Tomei pumps.

If i had a different balancer id be happy to push mine over 8000rpm, thats a jun pump and large sump. But the thing is - they dont need over 8000rpm to make decent power

[Dynamix]

I'm pretty sure you'll find its quality parts (eg ati balancer), balancing everything in the rotational mass and good assembly. There's really no other secret than that...

[Dynamix]

Off topic, hey N1GTR where do you get those little car pics for your sig?

[N1GTR]

A mate got a pic of the car and did it for me - i think there's a thread about them somewhere if you search

Back on track: RB30 > RB26

i see your mate was kind enough to leave the tangs off the front of your car.

im more than confident of this...

my rb26 gt-rs > your rb30 gt-rs
