Rb26 Sump Wats Needed To Be Modified To Fit Gts-t Body

[skylinekid]

i have heard so many ppl saying just use the 25 sump just use the 25... i dont think that is the best option high energy makes a 6'5 lt sump for the 25 but im unsure if i should get sumthing like that for the 26 block... ne suggestions

o and if neone knows if everything from a 25 like ac p/s pump alternator just bolts straight up to a 26 block but its an n1 block so neone got ne ideas on the subject

rb25 sump will not fit the rb26 - hence the need for adapter plates for the 4wd rb26 sumps on the rb30. either build a custom one, or have the rb26 sump modified to remove the front diff and welded up.

i believe the belts and spacing on the accessory pumps are different from rb25 and rb26

RB25 sump will fit rb26 if u want it rwd. To retain 4wd u need those adapter plates imho

RB26 sump is thick, provides strength.

The diff needs to be lopped off, and material removed.

Any decent fabricator will be able to knock it up for you if you show them and give them some specs and stuff.

I've had mine done, RB26 motor/26 sump, RWD. Works a treat

26 is drilled for both sumps which are interchangable except for the rb26 oil pickup which sits further out than on 25's meaning the 25sump will not fit unless you bash it out a good 10-15mm to clear. To use the 26 sump you will need to lop of the diff casing and plug up the driveshaft holes, make sure you trial fit it to the motor and the motor into the car before final fittment as it sits very close to the steering rack...(you need to take a fair amount of material off on the drivers side).

Im in the process of doing this now, Im sticking to the RB26 sump and modifying to suit.

The standard hi energy sump fouls the front sway bars, Also it help if you get a 10mm spring steel adapt plate in there.. If you're wanting to run a/c and P.S the pulley system on your rb25 should be swap over to rb26 including your harmonic.. or what ever it is call...temp. sensors has to be swap and a whole lot of other crap needs to be swap....

I got an extended hi-energy it holds 8.5lts and what ever the oil cooler holds.

Almost forgot the most important part. extend your oil pick up to suit new sump.

[DCIEVE]

Thats one hard to understand post! If the high energy sits lower than the std 26 sump (I assume seeing as your talking about extending the oil pickup) then it will likely also protrude lower than the engine x-member. We got my sump to about 8litres without going any lower than stock, sits perfectly level with the x-member.

surely there must be sumone who specialise in this sorta stuff. and would already know wat to do to be able to give me a bit more capacity as well as fit straight in neways thnx for ur comments

[DCIEVE]

you have all the information you need to either have the sump made or do it yourself, its really not that hard

[Adriano]

Performance Metalcraft sell a modded big RB26 sump for $1400, im sure for an extra $100 or so and they would make it RWD. Or i could do it for heaps less if you like.

[benm]

Slightly off topic but how much does an RB26 sump + diff weigh? any ideas?

[hungry6]

When you put the Hi energy sump in the front section of it foul o the sway br, well on mine it did. Also the pick up of the rb26 in abit to the side and it would help the engine a fair bit if it was moved further back infront of the trap door. But I cant remember it hitting the x member. Im getting old and my memory is failing. next time I get near my car I will take foto of mod sway bar and sump. I have photos some amongst the pron, too many to go through and find it.

As for rb26 sump and diff weight, just chuck it on a scale and find out.. weight is not somuch of an issue regarding street car, more so torque and power and skinnier mates.

You dont have a fabricator yet?

With your custom big setup, you'll be needing to find one quite soon id imagine
