Rb26det Into 33gts-t

[sam_33t]

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?

Not a question for QLD dude...

Moved to FIP...

hmm should sit in the same engine mounts shouldnt it and cant you get an adapter plate for the gearbox...dunno whos done this

for the money it would cost you to buy the motor and put it in you could get your rb25 going faster than a stock rb26.

Actually why didnt they release RB25DETT for GTRs?

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

So its a 5 figure adventure.

think of the extra power (and reliability) that could be acheived by spending that much on a rb25

[R31Nismoid]

Well i did that...

Its around similar in cost

RB26 has more potential, but it does cost more overall

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 use the original mounts

*standard gearbox should fit

*you will need some1 to do all the wiring

*need to modify exhaust to suit

*custom intercooler piping

all i can think of right now

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..
