I believe thats exactly what I said, you'd have to cut the hood. And to be exact, the RB30 block is 44mm taller than the 25 or 26 block.
Yes, right at 2 inchs...I can make it fit without cutting the hood.
We can internet race all night long. Im sure thats possible, and so is the opposite. It depends on quite a bit. Parts for a 6G72 are typically more expensive and theres not really a big following for them. And you have to be joking about a 6G72 destroying an RB26 240. 1000 lbs less weight AND more power potential.
What does your 6g72 put down? I have less than $5k in my RB26 build.
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. Its not about how heavy or light the cars are. Its how you get that power to the ground and keep it there. Just look at a Ferrari, some of them weigh 3800pounds but they sure as fuck will haul ass. Shit the Bently GT weighs about 4200 if I am not mistaken and its fast as fuck.
See now I'm starting to think you don't know anything about RB's or swapping them in a 240. You're way off.
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..
1. Show me one person that spent $1200 on the oil pan. Mine cost $120 shipped BRAND NEW. And you only need that on the 26 swap.
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.
2. To do it right and get "correct power" doesn't require any more than any other engine would, especially an SR. This is not the 90's, RB parts are not hard to get anymore.
get it right...
RB20 will require at least 3000 to get the right power reliably.
RB25 will be ok for a while but its a POS engine to begin with.
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.
3. Driveshaft and IC piping is the ONLY things you have to have custom. You can mount an RB in a 240 with STOCK parts.
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.
4. Wiring is an issue with any swap
Not to me it isnt.
As I said before, RB is not always the best bang for the buck. Yes an RB25 swap is a little more than an SR, but it has more potential. Stock for stock the RB25 would kill the SR.
To say that an SR is faster in a 240 is just rediculous.Yes you can make one faster than a mild RB, but at the cost of reliability. The RB has more displacement, flows better, more valve area, has a MUCH stronger bottom end, more potential, etc. The only advantage the SR has is weight. The 26 is essentially Nissans race engine. It is capable of 400+ just by tweaking it in stock trim. Theres plenty of RB26's running around the US pushing 600+ on stock bottoms with ne issues. There was a GTR that dragged in aussie land that put down 1800 HP on the stock bottom. You may do 1/3 of that on a stock bottom SR.
