hey guys, jus wondering if anyone could give me some info on putting an rb26det into a r33 gts-t? is there alot of modifying to fit the engine? also i imagine this is an expensive thing to do?

very expensive... being that i wouldnt run the risk of using stocker turbos.

So its a 5 figure adventure.

Whats your power goal? and how much do you want to spend? For 250-300rwkw, keep the RB25, do some internal work for anything over 280rwkw (rough rule of thumb). 250 - 270 is a good figure to aim for with a 25 as you can achieve that power with little more lag than stock, and keep the internals stock. Any more than this and your up for some big dollars

If you want morepower and little lag go for a RB30DET exelent base for 300 - 400rwkw less stuffing around than a RB26 and less lag.

my 2 cents

cheers

You can only use one engine mount the left one needs to be modified to clear the turbos and associated parts. Standard RB25 box fits. Sump needs to be modified.

Drive in drive out works out to be in the 10-14g range. Ive priced it all before....

Its pretty straight forward, RB25 box will bolt directly onto the motor, you can use the rb25 loom to run the thing, IF, you convert to a single turbo setup, <much wiser move IMHO, properly selected single eg, gt30 with a .64/82 rear will be on boost earlier most likely than the stock twins> if you stick with twins you'll need to get the loom from the 26 wited in to suit, as you will need to retain the dual AFM's and o2 sensors etc..

i used stock r33 mounts to the motor with nismo mounts to the subframe, and box..

as for the sump theres a couple of optiosn you can do.. use an rb25/30/20 style sump, you'll need to bash the side where the oil pick up is, and prevent it from leaking, <slightly dodgy method> or modify the gt-r sump, by chopping off the diff housing, and cleaning it up, then welding up the holes left from where the diff passes through it, that'll fit in perfectly and clear everything..

you can also get some extended units from various places, ive had one developed for me locally by a mate of mine, will hold about 10 litres of oil, and pretty crucial if your going to be belting it on the track, if its just a streeter you will be fine with the modified stock sump..

    • I don't care for these at all, but at least the underside looks straight and not rusty. A good basis for a long life. Many cars from Japan have been lifted with forklifts and f**ked almost irrepairably.
    • Yes, but it's not dumb or dodgy. You can build a perfectly good boost controller from a pressure reg, a relief valve (looks same same as a reg if all from Norgren or SMC, for example) and a check valve. I ran one for years. Only superceded with  EBC because I could get one for cheaps and wanted finer control.   THis mod is certainly not a sketchy boost mod, provided the boost is kept below the "spin to death" threshold of the turbos.
    • With ordering the belt, you're doing water pump and the idler and tensioner at the same time too yes?
    • This is just a dumb way of keeping the wastegate closed to make more boost. Undo it and either follow the factory setup or redo it properly. Manual boost controllers just use a spring preload to determine when to close in response to boost pressure so it no longer vents to atmosphere.
    • So for the wide band is a Bosch 4.9 correct for the Link G4+ along with a Can bus? Just get the Link gear or is generic ok too? Eg here: LINK LINK DIGITAL WIDEBAND CAN MODULE WITH BOSCH 4.9 SENSOR : KYP Performance House
