Talking Difference between 20b and 26b swap?

Hi guys ! I'm new here so I don't really know for sure if im posting this in the correct place but I've always dreamt about making a 26b turbo swap in my fd3s and I wonder if anyone knows the price difference between that and doing a 20b turbo swap? Also if anyone knows the struggle to get it in there
Sorry for misspelling, I'm from Sweden so my english isn't really flawless!

Thanks

it all depends what you want that makes the price change, defined auto works just built a 4 rotor for there fd, and there one of the best in the usa!

Thanks for responding !

Well, if I'd get myself a 20b I'd aim for let's say ~750WHP.
But with a 26b I'd aim for 1000WHP since it's not that hard.
Do you know the price difference between just the engines? Ported and all seals fitted etc? I've heard that it takes a lot of time and effort to build a quad rotor compared to the simple 20b which was production made.

Thanks

The primary difference is the entire 4 rotor setup would be custom, where as the 3 rotor setup has atleast half or more of a long block available with tons of knowledge available. You can find a lot of information on how to get the 3 rotor working, and if really on a budget, run it with the stock twin turbos/ECU. The 4 rotor setup on the other hand is almost completely custom, no off the shelf intake, exhaust, or subframe setup would work. It would need a ton of fabrication and if you needed a tuner, it would be very difficult to find one. Regardless, it would still be worth the time and effort if you have the available budget and if you have to pay shipping/taxes already - it may help negate the differences. I suggest you contact multiple 4 rotor vendors and get a realistic timeline and budget together and compare the pros and cons with them, if you're serious. I don't think many people here have the real answer of costs for this type of work. I would not anticipate either to be under $20k in the US unless you went with a bare-bones 20B or a setup already built and ready to go. It may be different in Sweden though.

I would also ask yourself, what do you want to do with your car? If it's a street car, a 4 rotor would be vastly overpriced for the typical person. You also have to think about the drivetrain because absolutely none of the stock equipment could stand up behind a 4 rotor, let alone a properly built 3 rotor and even some 2 rotors.

Just to throw some numbers out: a well built 2 rotor running in the car with around 600rwhp costs around $10-15k average doing as much labor yourself as possible. A well built 3 rotor setup running in the car with around 6-750rwhp would average around $20-25k USD here. Obviously this is doing as much labor as possible yourself. A well built 4 rotor shortblock - ENGINE ONLY, would be around $25k USD by itself, not including intake, exhaust, ECU, wiring, fuel, transmission, rear end, axles, etc. You can see why there are not many 4 rotors driving around with the $$$:HP ratio jump between the two.

Super thanks for this answer.
I was thinking to use it on the streets even though the cops won't like it hehe but still more of a beast that u can take to the track and have a blast. IF I'm gonna do this I won't hold back on anything, everything will be dead serious. So obviously with a gearbox etc etc etc it will cost up to 50k USD at least.
