i'd take the RB over SR just because it has more potential for power. Then again i do like autocrossing and i dunno how the RB would affect the handling.

ah, ill let you guys blow your money on these, just so that i can buy up your spare engines and parts but between those 2, i honestly don't think that the sr was engineered well, why would you go through the trouble of making it dohc if you are going to keep the rocker arms? rb is obviously a superior design, but have fun sourciing replacement parts for it, i hope that it isn't your daily driver

RB all the way turns the 240SX into a mini skyline plus I love Inline 6 cyl

An SR is cheaper and right now, is easier to find aftermarket parts for without importing. That is obviously changing.
Face facts, not many (none) of us will ever build either motor to its full potential. So why go RB for that reason. Most of us are not that rich.

RB25 would be bad ass for wangan. But otherwise, just SR. I don't see why people are doing the RB20. I have to aske those crazy Japanese guys why they keep swapping their RB20s for SRs. Stupid Japanese people.

HAHA!
(I have goals) 1st GOAL! Turbo the KA and make it the most powerfull KA ever... Whats the most a KA has had?? I think 600hp would win so thats my current goal.. 2nd GOAL! Stick the KA in my bro's 1980 Maxima (1 more year and no immisions baby) and get a more reliable RB26DETT in my current car... Only slightly upgrade the power... (like 400 maby?) I could do this in the next 4 years... (unless i get this job in spokane)

rb25det is hype, rb26 is not. If i had to trade my sr20det for any engine it would be an rb26dett and only if my goal was strickly for wangan. I however enjoy drag racing as well and adding the extra 2 cylinders would knock me into outlaw which i would not be able to compete in. I do wangan with the sr20det works great, nice center of gravity...just right i think. To all of those who think the rb20 or rb25 is the best engine to put in an sr20det , have you ever done wieght comparisons? full engine tear downs, piston and rod balnce, wieght and specification tests and checks? Have you raced both in all arenas of racing? and done real bare Knuckle comparisons? I have had eperience with both. I prefer sr20det for the novic and intermdiate driver and in my opinion the rb20 is not worth the trouble, the rb25det is good for sub 450whp levels and the rb26 is the best option but only for advanced driver or intermdiate who plans mostly wangan or top speed racing... this is my opinion based purly on first hand experience with all of the above stated engines... The h22 is nice but how many competitive honda drag racers and road racers are swapping out their b20 vtec and b18s for them? Not many, same in japan the sr20det is more favored for everything in s chasis. Just my opinion. All excellent power plants and power making platforms tho...saying that the rb has more potential for power is completly unfounded, im waiting for ngr performance in florida to get some ACTUAL dyno numbers down for the stock internal rb25. The rb26 yes is superior in everyway to sr, but rb25 is different, not as strong internally, i have seen both engines inside. Not the same, similar but not the same. The sr20det has been proven in the united states first hand to be capable of 600whp on stock bottom end for extended periods of time, i have pushed over 350whp on stock head gasket for more than a year at a time before...and raced on them every week...There needs to be more HARD proof from reputable tuners. I do have an rb26dett powered s12 in the works for wangan and drag in the near future the rb26 enegin in king the head design is also far superior to the rb25 and rb20 depending on model. Another note on rb25det i saw in the "drift" auto magazine passed out at d1 the one with "d man" on the back an article with mark slide squads s13 coupe wiht rb25det, it said he has 400hp? is this a dyno number? has the car ever even been dynoed? this is the kind of irresposible reporting i expect from these kind of editorials by members of motorex but i mean this is completley unfounded. Is this a flywheel guestimate? be wary of the hype out there guys its thick like a cloud of mustard gas and i feel myself gagging everyday...

KA24DET Cheaper than both, Greddy turbo kits are now like $2,800 and rebuilding a $300 KA would be more fun (to me anyway) then just dropping in an overpriced SR/RB. Plus support for the KA-T is expected to increase. But, to be on topic, SR over RB because of the extra weight. I'm into drifting/autoX more than drag/wangan so I'll take light weight and faster revs over 650HP+ potential.

then you'll appreciate the fact that the SR w/it's turbo system is lighter than the NA KA. (It was the factor in my own plans)

The 2JZ-GTE swap into an AE86 has been done, Jap Peoples do it for Drag racing. Theres no such thing as a 2JZ-A80. Maybe your confusing the Supras chassis code. JZA80 for the MKIV supra.
How is the RB series engine the best engine ever? Lol. The stock USDM 2JZ can take it(The USDM 2JZ is the best 2JZ, even better than the JDM Supra RZ's engine.)

There's a guy over on the NICO board who hit 597whp from his stock internals (aftermarket cams only) RB25, and another guy hit 490whp with his stock internals RB20...
The RB20 is a bit lighter than the RB25, mostly because it uses a lighter transmission, is easy to install, and I picked up my whole swap for under $1000. I'm doing RB20 because they sound 10x better than an SR, it can make the power "I" want (~350whp) and I could afford it. Turbo'ing the KA is cool if you want 250-275whp, but if you want more, you have to build the engine, in which case, a stock rb25 is better off than that or a stock rb20 and it doesn't weigh that much more than the KA did in the first place. Anyhoo, just my opinion. Nick

Haha...I guess I haven't been reading up about them as much lately. I guess, though that at those levels, the engine is pretty much maxed out until you build it. For some people that's cool, it all depends on what you prefer: revvability, exhaust note, max power levels..etc.
