RB26DETT W/ RB25 Tranny??

I have yet another engine question for u guys. Wut if I were to have unstablehybrids.com get me an rb26dett engine with the rear wheel drive tranny of an rb25? Would that even work?

YUP !

but you would need to talk to them though :flash:

Yes....it will....there are a lot of other modifications we'd have to do to the car....but its doable....just about $12K or so to do......YIKEs.....

your engine/tranny conversions are doable....but why? the engine alone costs between 9-24K...and to have them custom bold the tranny..well i don't even wanna think about how much extra that is...also...what kind of car do you want to put this on??? You gotta consider that the RB26 motor is exactly what it represents..2.6 liters of displacement..which means it won't fit in the engine bay of a dinky civic/integra, and not even the 240sx. basically the RB26dett motor was designed specifically for the Skyline GT-R V-spec...i'd suggest you think of OTHER engine mods unless your uncle is Bill Gates or you have a rich relative about to die

Why? Because entrepreneurs form the driving force of any industry.

Your statement about displacement being the primary factor in size restriction is a bit off. You can fit 5.0L V-8s into Miatas which previously held 1.8L engines. You can fit 6.0L V-12s into compact C-class Mercedes engine bays. It's common knowledge that every engine was specifically designed for a certain chassis, but that doens't mean that it is flat-out impossible to create a hybrid. And no one should ever impune those who spend large sums of money developing hybrid masterpieces; it's only because of THEM do the prices get cheaper (i.e. the first of the SR20DET/240SX transplanters payed the price of having to pay big cash for nonexistant R&D to make this happen; it's now relatively a cost-efficient modification for everyone else).

This is very possible. It has been before, and it can be daily-driven.
Check C-West S14a out with an RB26DET.

well that and... a lot of people in japan have already done the RB26 transplant, they seemed pretty happy in the pictures the Options took of them. Morpheus is right, have you ever seen the engine bay of an S14? I think there's enough room for 2 engines to fit in there. also, displacement doesn't indicate outter dimensions. the RB20det is the same block as the RB26, just different lower end that makes it a 2.6 liter. shoot, a 400R's 2.8 liter engine's the same, if someone makes a stroker kit to go up to 3.0, you get the idea.

hey, for $12k, I'd go for it... if I had $12k :( I don't
when I do, well, let's wait for me to end my studying days and move on to working days.

Until then CKGUY, go for it, then I'll ask you how you did it :)

morpheus, just 2 clear this up, the rb26 wuznt just dzined 4 the v-spec skyline gt-r. and i am more of a car person than a motor person, but from wut i have bn told, the displacement of and engine is how much oil it can hold(??). If that is tru, than it wouldnt b 2 much of a problem 2 put the engine in the car.

The RB26DETT powerplant was specifically designed for the GT-R Skyline. The 2.6 liters of displacement were marked at that size to hold an advantage in certain classes of racing. But this isn't even what I'm talking about from earlier. What I was saying is that automakers draw up each engine with a specific chassis or platform in mind, BUT this ideology doesn't mean that it is impossible to use some other engine to create a hybrid.

The displacement of an engine is the total volume of the cylinders. The volume of one cylinder is found using the bore (cylinder's diameter) and stroke (distance between a piston at top dead-center and at bottom dead-center), and that figure is multiplied by the number of cylinders.

If the displacement of an engine is how much oil it can hold, then just about ever passenger car in the world would be between 3.8L and 4.7L, considering that most cars require 4-5 quarts of the lube.

Morpheus is right, the rb26dett was made for the Skyline GT-R's and GT-R V-Spec's. he is also right about the displacement thing he mentioned earlier, i have a 83' Mazda RX-7 that originally had a 1.2L Rotary engine in it, but i blew the motor and stuffed in a 5.7L TPI Chevy V-8 in it with actually ease!

Nice! :D It's great to see some other '70s or '80s rear-wheel-drive import road king taking in domestic muscle. I just love to see those 280Zs powered by raw V8s! The RX-7 mix is also a nice setup. It's a bold statement for Stateside folk to make imports their own by doing this.

thank morpheus, your probably the first person to compliment me on my v-8 swap in my rx-7. i told die hard rx-7 guys about this and they freaked out! they said that it was demoralizing the fact that i put American muscle into my import. they all said the same thing to me, how come u didnt put in a bigger 2 rotor, or put in a 3 rotor, and i even got people telling me i should of put in a 4 rotor. i want to tell these people that i dont have a 3rd gen RX-7 for the millionth time, and if i did own a 3rd gen. RX-7 i probably would of dropped in a 20B 3 rotor, but since mine is a 1st gen. RX-7 i needed something more than the rotory for my driving style. hell the V-8 i have in my RX-7 now has more than 3 times the HP as my original rotary, and i even get way better gas mileage with the V-8 too, i used to get 17mpg in the city and 22 on the highway with the 1.2L rotary, but with the TPI V-8, i get 21mpg in the city and 29 on the highway, due to the 6 speed tranny i got in it. to add to that, i do high 11's in the quarter mile with it, and do 0-60 in 3.8 seconds!!! id like to see a naturally aspirated 2-rotor do all this and still be street, emissions, and california smog legal!!!:lol2:

who ever said the engine cost 9-24k most be smoking something i bout my rb25det for 4200 and then i bought my rb26dett for 6

LOL!

Perhaps they don't cost that much, but I bet there are a few ignorant fools out there who will probably end up getting ripped off and paying that much anyway. If someone gives ME $9K-24K, I'll keep my mouth shut, give them an RB, and use the extra cash to buy an S13. :hehe:

dude with 24k you could do hella more then buy just A S13 all the stuff im doing to my s14 so far cost me 15g including the RB25 and theres still at least another 9k of stuff i want

Oh of course. I just said it that way in case I only got 9 grand, cause that wouldn't leave too much extra cash for parts (after buying the poor sap an RB for the lower price you mentioned), but yeah, the more money the merrier I would be.
