I was entertaining the idea of swaping out my ka24de engine with a rb25 or rb26. I wanted to no what the bad part is about swaping out and putting one of them in? Money isnt a big issue i no the amount i would proble need but i want to no the mechanical difficulty is with this? IS there any reoccurring problems with this swap? just give me your input on my indea.thanks

um downfall to an rb25, besides being more costly than say an sr20, too much power for a p**** is all i can think of...

A lot heavier and thus much worse handling, hard to find parts.

Yes, finding parts for it might be difficult and doing an rb swap is rather costly...but worth it imo. If you are gonna do an rb26 swap, be prepared to be spending at least between $8,000-$10,000 btw.

Yes, it is more weight, around 150lbs more for a rb25 swap. the weight isnt important tho, its the weight shift. it really depends on engine/transmission and how you mount it (i.e. crossmember or aftermarket mounts), but realistically your looking at 2-3% overall weight shift. if you look at the numbers in a 3000lb car thats only a 60-90lb shift forward. just to put that in perspective, 12 gallons of gas weighs roughly 100lbs so there is more of a shift between a full and empty tank, than a RB swap. IT DOES NOT DESTROY THE WEIGHT BALANCE OF THE CAR

thats a sticky, research before you open your mouth.

Well. From what I can interpret , you misjudged my response and got a little butt-hurt, Sally. The point is if cost isn't a problem do it, thats usually the only restraint in building a car, but since you've priced it out that doesn't matter right? The RB25 is pretty much bulletproof so there isnt much to complain about. Take your somewhere else if you cant handle the internet...

wow guy relax, thats how you get banned.

He was correcting misinformation stated by someone else. Rb25 is a good motor. I have owned several rb20/25/26. Weight shift is not noticeable, and parts are infact easy to find. I get my parts thru the dealership. If you go with rb26 you will need a rb25 oil pan and trans. Rb25 and rb26 will require some slight firewall hammering to.

Dude no one here insulted you, they just answered your question.

Did you forget to take your medication or was the store out of tampons?

Either way someone ban this fool. If this is how he reacts when someone answers a questions thats been probably covered many times before imagine how he'll react to other things

Here man, http://www.prescriptiongiant.c....htmlI know its a bit pricey but tell your mommy that its good for you

the only thing I can think of is emissions and some parts.

if you go rb25, which you will (once you see rb26 price swap) The drive shaft will be costumed made. And prepare for some awesome I6, but there is a RB forum with great write ups regarding to information.

also you got trolled by a response towards another person.

Your stay will be short if you continue to act like that nooby-doo. If you don't have much time on your hands to search for 15 mins then maybe you shouldn't be doing swap? Don't b**** when people give you easy to find answers.

Consider me corrected. I've heard from numerous locals their cars handled worse with the RB and my point was parts aren't quite as easily accessible as, say, a KA. I was simply going off that and hadn't read the sticky, but now I know. I suppose suspension tuning could offset any negligible effects the engine had on handling.

OP, why are you so upset? They didn't say anything negative toward you, simply educated me.

Maybe someone took a peepee in the op's breakfast. Look no engine swap is completely bullet proof you can run into a problem at anytime with any sort of engine so just do it. I mean if your worried about the unforseen future then just keep your stock junk in there and drive it.

Man, the F word has really become a part of the American dictionary. It has a verb form, an adjective form, and an adverb (not seen here, but it exists).

i've seen plenty of rb swaps in pictures, but after i saw an rb20 in an s13 for the first time in person and was able to get close and examine it, i would never swap an rb into an s-chassis. it just looks too tight for my liking.
