RB25DET or SR20DET

[GT Ranma]

Ok, I am still debating where to put a RB25DET or a SR20DET(S-14) into my 95 240SX.

Now, I put it in this Forum because I want to hear what RB25DET owners thing about thier engine. They are compairitivly priced, so that really isn't to much of an issue. (I know I have to but parts to make it fit, not that I know how much that will be.)

What I really want to know is what everyone thinks about thier engine. Does it get good/horrible gas milage, is the torque to much for normal every day driving. That kind of thing ^^

I owned a 1995 Silvia K when I lived in japan, so I know how that engine acts ^^;

Loved itGreat for what it isIts daily driven in Japan, isnt it?

RB25DET

[GT Ranma]

Well, I live in Arizona now, so it'll be daily driven in arizona ^^;

Hrm, I've seen some RB25DETT engines floating around, are they stock and/or any better then the RB25DET?

*nodnod* I see. Doesn't spin the tires every time you try to get on it? ^^

Man, you better put your flame suit on for not searching a bit better but I'll answer a few of your questions as best I can.First, an RB25 will probably be more expensive to swap in than an SR if you buy the mounts, custom driveshaft, and pay someone to do the wiring for you. Second, RB's get good gas mileage as long as you keep your foot out of it. Third, on paper, the RB doesn't really have appear to have THAT much more torque than an SR so it's not like your going to do a huge smokey burn out every time you drive (unless you want to of course).

There are many more thorough answers to your questions and you'll find them by searching a bit more...

wow where have you seen a rb25dett? cause im almost certain that engine dosent exist lol.

and i hate to be such an ******* but just search! this question has been beaten to death. just do your own damn research. judging by you having to ASK this question im gonna say SR just because i dobut you want to deal with a RB swap.

There is no RB25DETT. If there is, it's custom built.

There is also alot more information out there on your question. You need to search this forum, and many others:

skylinesaustralia.comskylinesdownunder.com240sxforums.comzilvia.net

If you don't know a thing or two about engines/displacement or efficiency, then just go for the SR20DET. It's a very strong engine, just like the RB's.

If you do not know why you need 6 cylinders, what it takes to have 6 cylinders, or how to do custom wiring and source rare parts, then go with the SR. It'll satistfy. Or RB20DET.

tho there isn't such thing as RB25DETT(but there is 26), there is a company that makes a manifold for TT's on a 25, don't remember their site though.

. . . Um, yeah, well, I know all that. So you didn't tell me anything new. As I said, I wanted OPINIONS . . . Why don't you type in 'Opinion RB25DET' and see what you get.

Hrm, 50lb of torque can meen alot depending upon where it is in the powerband. My 1995 Silva K would spin the tires when it hit the powerband, and that had Yoko Z rated tires on, not cheapos.

It's odd that I can find that the SR20DET can get about 26-33mpg, yet search for anything about gas milage on the RB25DET and all you find are people arguing about if it has good gas mileage or bad gas mileage.

Also, I have owned a 1997 Skyline GTS-T, and that sucked gas like it was free, I can't really see the GTR engine being any better. But then again it was pushing well over 300hp.

As I said, I know all the technical details, besides gas milage/handing, and just want to know what people think about doing it. Also, if you doubt we can do it *shrug* You might be right, we never did a RB25DET yet.

Edit: Yeah, TheOne, that's what I am talking about. So, they don't come TT, that's what I thought ^^ Thanks! I knew I had seen some RB25DETT stuff floating around for sale. I'm not completely insain yet XD

RBs are just a pain. (in every aspect)

What are you running on krayton?Yeah, even to just buy replacement gaskets is stupid expensive. But then again I can always have my bro still in Okinawa run down to a junkyard and pick up whatever I need XD (Long as it's not custom)

he has a 25

and you can have someone in japan go get the parts? then what?wait a week for it to get here?

its more than the cost, its the availability of parts.

[krayton]

where in Az are you?

i still say go with the SR for less headaches and the jdm coolness

but if i had to do it all over again id go ka-t

. . . And how is that any diffrent from ordering from the net and waiting a week or so for it to get here? I live over 70 miles away from the nearest Big City, and over 30 miles from a crappy little one.

SR or RB is going to be just as hard for me to get parts.

@kraytonI am in 'Deer Creek Village' :p It is south of Payson, real middle of no where.

Hrm, is it really that much of a hassle? I drifted and street raced for 2 years while I was in japan (and yes, the Okinawans make us americans look like children). I blew a turbo, lost an exaust, had to get my engine rebuilt and had the hose going to my intercooler rip off. . . And that was ALL on my Skyline GTS-T, my Silvia didn't have a single problem the entire time I raced it . . .
