Rb's

[StupidBikerBoy]

Non-N1 bottom end RB26 cant handle more than 550 and be reliable. RB20 bottom end cant handle more than 380 and be reliable. Rb25 is just a POS..I have yet to see one run for a solid year of what I put my old RB20 through.

Was it you who raced Ch@dbee with the RB26 powered 240sx and lost??

No, wasn't me. And considering the the 26 is actually 320 to 350hp stock depending on year and a 240 is lighter, Chad obviously out drove him or he had issues. Im putting down close to you with no problems and I drive the shit out of it....

I cant speak for RB20's but I have seen more than a few RB26's putting down over 550 "reliably". And a 26 will DAMN SURE handle more power than a 6G72. What good is 600 whp if you cant use it?

it puts down 320 stock, I turned the boost up to 14psi from 7psi. I put about 5k into it and I have 600~650 awhp

Thats funny, I have less than that in my build and put down similar numbers. And I even spent a little extra on a few parts just for extra reliability. And have 4000 rpm of full boost to play with.

Since when has a CUSTOM oil pan cost 120? maybe a stock pan...but not a custom pan which is what I am refering too

Let me drop a little knowledge on you. A RB25 pan will bolt right up to a 26. If you really have been working on RB26's for 5 years, you should have known that. So why would you use a custom pan if its not needed?

As for the others, its not needed.

RB26 is a great motor, dont get me wrong, but in a 240sx it is TOO MUCH without AWD...my AWD would destroy your RB26 car on a track, I have raced RB's they are nose heavy and have oversteer like a mofo...you are either going to burn up your breaks or burn up your tires and your suspension is going to get a hell of a workout as long as you dont speed shift the transmission and blow a syncro.

Sounds like you have only dealt with s13's. Not a big issue in S14's, and nothing a little suspension work can't handle on either..

As far as a 4000lb. car destroying mine on the track, my 2880 lb. car with 13 in. brakes, tein flex suspension, and similar power thinks that is funny.

But IMO a less powerful SR would be a better choice if road course is your thing.

You are wrong again. You can use a stock driveshaft on RB20. You can use stock intercooler piping on all of them. You NEED mounts or a crossmember. Down pipes for all of them.

I have more experience with 26's. On a 26 YOU CANNOT use stock intercooler piping without atleast modifying the hot and cold pipes. You CAN use an R33 cross-member to mount the 26 (would come with the clip), which as I said is a stock nissan part. Downpipes are a given. So, no I am not wrong, and I have a car that can prove it.

Not to me it isnt

Dude, you brought up the wiring, not me. Wiring has to be done on any swap, so there was no point in even pointing out.

Think what you want, I have been working on RB's for almost 5 years now. I worked on more RB cars than you have ever seen...worked on more Sr cars than you have ever seen. I DO NOT like RB's in 240sx I dont mind RB20's in 240sx because its not too much for the chassis although it does weigh alot and makes it nose heavy. Now...RB26 in a Skyline is fun because you have AWD..

Im glad you can assume that you know more about RB's than me, but you obviously have only dealt with 20's and 25's. Personally I wouldn't waste my time swapping one of those, only 26's. Don't mind 20's in a 240??? They are just as heavy as a 25! As far as not liking RB's in 240's, you are entitled to your opinion, but I find that funny coming from someone with a 4000lb. mitsubishi. There's a reason why there's not many around modified. Enjoy it while it lasts.

You are giving out a lot of misinformation. Im not going to continue to argue with someone that doesn't even know what he's talking about.

I challenge you to prove anything I have said as false.
