hey guys, these questions seem real nub, plz no bashin ><

ive been searching for answers to these questions:

im trying to decide on working with the extra cash i have and keeping the KA24, Dropping an SR20 or even going for the bigger Skyline 25 engine. What is the horsepower/torque gaines and what is the overall estimated base 0-60 when put into a 1995 base 240SX (no weight deduction)

i read a tech article on each but so far i havent seen stats for 0-60 speeds and such

Im thinking with the sr20 0-60 might be 5.5 seconds depending on the boost you apply. RB25....maybe a fraction of a second faster. Just a little note, the RB engines are mainly for show as they can be quiet expensive to buy/install/care for (just thought you might wanna know).

Blacktop s14 sr20det: 220hpRB25dett: 280hp?? (please feel free to correct me if im wrong im not really looking up the info for the hp/tq, its more from memory)

S14 Blacktop is 217 Hp and 202 TQRedtop Sr20 is 202 HP and 188 TQRB25DET is 250 HP and 220 TQ

I do not know what the 0-60's are.....but the RB25 has more displacement and more potential for power if you ask me

Sr20det redtop - 2o5hp 2o5ft lbs of tqsr2odet s14 blacktop- 22ohp 2o5ft lbs of tqrb25det (skline GTS-T) 25ohp 22o ft lbs of tqrb26dett (skliny GT-R) 276hp 28o ft lbs of tqthe RB26dett was only in the GTR, there never was an RB25dett (unless you added another turbo onto a single turbo'd rb25det) and the RB25det is great because of .5 liters more displacement, much more potential for power, but not as easy to find parts for, installation isnt as easy, and maintenance may be a lil harder only because of troubles finding parts

I'm guessing typo. You mean "RB26DETT = GT-R" right?

That's pretty funny....seriously....

It takes alot of work from an RB26DETT to get 400 to the wheels, and the engine has twin turbos, the engine is built up stronger vs the RB25, and uses alot higher quality compoents...

hey, just wonderin what kind of results would you get if you took the turbo off of any turbo car, and upped the compresion. i know it wouldn't be as fast, but you would almost never have any kind of problems right?(other than the rugulars.oil etc.)

Rb swap really favors people who want a muscle sound to their 240 or who want 500+ hp. There is no reason you shouldn't get an SR. It has a lot of power potential. Its not really a huge motor like the rb so it wont take up a lot of space in your engine bay. And its a lot cheaper to install and maintain. There are not a lot mechanics in the US that can work with an rb powered 240 which is a huge factor into why you should stick with the sr swap. Ask anybody on this forum who have swaps how many times they need to tune their car on a yearly basis. Then again if you make a lot of money -$40,000 or so a year- go for it(rb swap). Its different.

The RB isn't worth it. Unless if you go RB26DETT.

But then to make 400+ whp, you'll need alot of work. New Turbos, probally HKS GT2530-GT2535s. Injectors, Twin Z32 MAFs, strenghtening of the transmission, FMIC, Tuning, downpipe, exhaust, fuel etc etc...

500+ hp on an RB25DET is stupid if you don't have lots of money, making 500+ hp on an RB26DETT is already hard enough. The RB is a nice engine, but it isn't the god of all engines either.

The SR and CA engines are a better choice for the Silvias because they're lighter, and even though you don't make as much power your power to weight ratio is better.

If you want to argue about the true strengths about the RB, then do research. RBs in north america do not make lots and lots and lots of power easily and reliabilty.

The RB20DET is a really good value for the money if you want to go RB.

Do you have any sort of experience in building RB's?

OMG! You're in Austin?! I was just there last month in the Apple Bar, Whiskey Bar, Red Fez, Fado's, and then on to Sullivan's for dinner. Nice town, lots of talent, but I looked a little out of place as a 36 yo in a college town. One of my friends there has an Acura TL-S with one of my stroked 3.5 short blocks.

Anyway, it's a 95 RB26DETT. Bought a clip, and carefully removed everything. Has aluminum fenders & hood, front bumper (has small holes cut in it for fog lights), grill, instrument cluster, complete uncut harness, AWD trans (for someone with a GTR whose trans is shot) ECU.

What's missing? MAF's, FMIC, headlights, brakes.

Like I said, I bought it for myself, flew to Nebraska to buy a *pristine* 97 240 SE to install it in. Less than a month later, an 80 year old man in a Grand Marquis pulled from the shoulder of the Fla Turnpike directly in front of me and *stopped*. He's lucky he's alive, so am I.

Inspection under the valve cover reveals little to no wear on the cam lobes, extremely clean. Haven't done a compression test, but I've bought dozens of swaps from this vendor & have never had an issue with him. He bought the whole car for himself when in Japan, due to a screw up, they cut it in half before shipping!!!!

Asking $5500, shipping would be expensive with the front sheet metal & all. Would consider delivering in the southeast, Austin would be a haul, though.

Have more pics. In addition to the transplant car being totalled, I'm also in the middle of a divorce & can't get my kids in a 240 anyway.

Wow!

By looking around here, it seems the prices on these have dropped like mad in the year or so since I bought the clip.

I paid $5,000 + shipping for the clip, now I see they're selling for $3,000.

Wow!

I have a video of a guy with an RB25DET in his '95 240. He only has an upgraded fuel system, and turbo. He is making 587hp with no major upgrades to the engine. He stopped at 587hp because the stock headgasket was about to blow... The car could of made higher numbers...

I'm not sure what you mean by muscle sound, but the RB is not a loud engine at all...

So the RB is a huge motor? The SR is not? Just because it has 6 cylinders its huge? The RB20 and the SR20 have the same displacement, so why would you make it sound as if its some monster of an engine... The RB is alittle bit bigger, but not enough to really make a difference. As for the mechanic thing... they are both made by nissan why would they be drastically different? If you did an engine swap why the **** would you bring it to a regular mechanic? All cars need tuning...

Anyway, the SR is not the be all end all engine that fast and the furious has made it out to be. The RB is a great engine, after all, Nissan did put it in its signature car...

The Rb is not loud??? Have you ever heard an R32 drift in person?? I have, and i live in jersey. Its is definetly totally different from the SR power and TORQUE. I would never bring my car to a regular mechanic *****er(im gettin my sr this June from JGYcustoms). As far as I know Secret Services(florida), Import Intelligence(pennsylvania), and JGY Customs(virginia) are the only shops on the East coast that would even deal with the RB swap. I dont know bout west coast, but im pretty sure you guys have a couple of shops that have some experience given you guys have a huge nissan craze down there. The *****en point is if the mechanic has never done an Rb swap before, hes gonna charge you a ****load cause he has to spend time figuring it out. Do some research before you start talking.

I know John from SS, great guy. But Florida, although a peninsula, encompasses more than the coastline of the Gulf of Mexico.

The guys at Velocity Resources (Orlando) are ready & capable as well.

B&T Motorsports did me a very clean SR swap for me...they were slightly careless, but definately good work...if u use them, do price checks first tho...i coulda sourced all the parts for them for much cheaper then what they got me

If you want torque, try using this thing I call a KAT (KA24DET for you newbs out there, *cough* SSal007 *cough*)

"Having" torque is rather subjective. The SR will have decent torque because of its square bore and stroke while still being able to rev higher than a 454. Naturally, the KA will be a torquier engine, lending itself to earlier power delivery which is handy in corner exits. And the RB is just pimp. Not that I'm biased or anything, but 6 cylinders, the ability to rev higher than both engine and an iron block sounds good to me. :) But hey, it's just "for show," right? :rolleyes

Rb20 makes more power, SR20 makes more torque, pretty basic facts, not really an argument.

I hate these damn threads....

Anybody who thinks any of these motors are a bad choice has their head firmly planted up their own arse.

Damn, I guess youre right. I just though the 6 cyl RB would have more torque.Back to cost...With the prices they charge for an SR you could buy a RB25. Of course, you have pay more to installthe RB25. Its hard for me to understand why someone would swap a KA for an SR. I'm not dissing the SR but if I were spending that money, it would be for an RB.For the power most guys are looking for (250-300whp) KA, RB, and SR will all get you there
