rb vs sr
hi everybody.I had my heart set on doing the s14sr20det swap for awhile.but a friend told me that the rb25 swap was much easier and produces more power (that part was obvious) but I'm really starting to like the rb neobased on everyone's experience, which swap is easiest or more straightfoward?

Re: rb vs sr (GoSideways5)
It depends on what year your 240 is, if that’s where its going.With an RB, you won't have much room for the radiator, and its 180lbs more than an SR (or is that 180 more than KA, I forget). I have not done the RB swap myself If you have seen an RB stuffed into a 240 engine bay, I wouldn't describe the process of getting it there easy or even working on it very easy. I helped with my SR swap, have helped with other SR swaps, and all except the wiring is strait forward.
The RB has more potential for HP because of displacement, it sounds cooler, but it costs allot more and there isn't as much aftermarket as the SR so it’s going to be harder to get parts.
Do more searching, but what you will most likely find is opinions disguised as facts.

Talk to these guys. They've done a bunch of SR and a few RB swaps.

Re: (DRFT(kinda))
your friends an idiot...I haven't done either but the SR came stock in this car. It pretty much drops into place, then has to be wired up.
The RB25 is from a compleatly different car and IIRC requires at least a modified/different crossmember....
there is no way its easier, or cheaper then an SR....

Re: rb vs sr (GoSideways5)
Holy rb section batman! It's an rb swap guide for the 240sx on our very own nico website. Who woulda thunk it? zerothread/185294
That should give you a degree of understanding in what needs to be done.

Re: (180fan)
Belive me man I couldn't manage the 240 section, Id be(am ) to big of a troll....better man then most
Seriously though Teddy's was great, read up on what it takes to get an RB in an S chassis...I wouldn't be the one to listen to but from my understanding the work, and money involved is significantly greater then an SR.
One thing is for sure....Your friend is no longer allowed to give advice on the 240.

Re: (Red coupe)
thanks a lot guys, definitely helped in my decision makeing and I'll probably start a thread monitering my progress when it gets going. the friend I talk of was actually just saying he heard this, and I didn't think it made sense either, but I figured I would ask around.
Re: (GoSideways5)
lol yeah alot of people hear alot of things Ive kinda learned to just stop listening if they cant explain.....
Like we said those each of the engines have a section, and in each section (seen here), any of the ones that are popular 240 swaps will have plenty of guides, and other information in the stuck topics at the top...Also don't forget to check out the KA-T forum as another option that is more on par with the SR swap...(just please don't make a KA vs SR topic...that would likely get you killed)

Oh don't worry bout that. I already have. I trust these guys pretty well. I knew then for about a year before my deployment. Been talking to them on a constant basis and so far so good......ddgsxr504 wrote:Well make sure you come to us for Q's once you get back and get your car.

Re: (DRFT(kinda))
Personally I like the SR... but then again I'm biased look at both motors and see what you plan on achieving in the future.
IMHO, the RB in stock trim is impressive and sounds a lot better than the SR. I find it to be more of a nice daily driver type of motor, since it has decent low end torque and good HP to back it up when it comes to spirited driving. As for installation issues, all you really need is a reputable shop that will mate your wiring harnesses together, custom engine & transmission mounts, electric cooling fans and IIRC front halfshaft. If this is what you decide but have trouble locating a place to do a quality harness or need mounts for a decent price, shoot me a PM.
The only drawback I see of having an RB is the aftermarket market support compared to the SR. Also, I find the OEM coilpacks on RBs tend to quit due to old age.
The SR on the other hand has almost unlimited aftermarket support and for being a popular motor, used parts or parts motors are very easy to come by. Installation requires mating the harnesses together and the physical grunt work of putting everything back together.
In the end whichever swap you decide to complete, you will find that whichever route you choose, you will be happy with

SR has awesome aftermarket support stateside. The RB's though are really beginning to pick up. If the cost of the parts/engine/swap weren't so expensive, I'm sure there'd be more folks on it.
Depending on how far you decide to go with an SR, you may have regrets later and kick yourself for not going RB. I have personally been there and although I've dumped quite a bit into my own SR, I've come to terms with it. Either way you can't really go wrong. Depends really on what you're doing though. If you're hardcore about circuit racing, I'd opt for the SR. If you want more power and to do less stuff to make good power and have the cash up front to do it, then I'd go RB. But I don't really see any disappointment in either engine.
