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?
6g72 can handle 700hp with no issues but 600 reliably. Go speed shift your RB25 Tranny..lol..Getrag OWNS you bitch.
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.
My 3000GT is stock. 320 is stock. I have 0$ in my build...LOL..fucking dumbass.
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?
Hmm..I already know that you twat. I am talking about a custom Aluminum/Stainless Oil pan. Go ahead..build your "drag" rb26...when you starve the engine of oil I will laugh. You need a custom oil pan with baffles for your front sump RB26. Oh and the stock RB25 oil pan has to be notched fucking dumbass or else the oil return will not clear, that would make it not bolt on. Also just so you know, go ahead and leave out the head return lines for the oil...so when your engine oil pools in the head I will laugh at you as well.
As for the others, its not needed.
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..
Yes I have primarily delt with S13 RB's but s14 RB26's. I know my shit man and would spin circles around you.
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.
WOW...you have some money in your car...WOW...LOL..AWD will OWN you on a close circuit track. I hate to inform you but you will be having issues with oversteer while I have torque steer that is keeping me in the corner, thus...helping me get out of the corner ALOT faster. You have 300zx brakes and they are not 13"s. Your caliper will explode if they are the aluminum ones and you over brake the car. Please go weigh your car, 2880 is more like 3200. You probably dont even know how to properly adjust your suspension to make it work in your benefit.
But IMO a less powerful SR would be a better choice if road course is your thing.
I hate SR's, I like RB20/30. thats it. I got my 3000GT because after I put in 5g's I have 600+ at the wheels. No no labor included, I do my own work.
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.
want a cookie, you have the car..WOW..I already know what you can and cant use. with a mount kit you CAN use stock intercooler piping so STFU.

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.
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.
To the OP, check out freshalloy.com or skylinesdownunder.com, they have a lot more info.
