vullut The FD weighs nearly 1.3 tonnes. I ran mine at 430whp it was a good happy medium for a 13b, it was fast, fun and manageable.. If you go for much more power, You're getting into the territory of big laggy turbos, and RX-7s need all the low end power you can get since it has about as much torque as a pensioner with arthritis operating a screwdriver.

[@renyn21]

This stuff is awesome, I'm glad there are people willing to film it and share it with us. Before KZbin I didn't even know this type of stuff even gets done, dyno-ing and dialing in custom built cars to this level, definitely doesn't happen around these parts of the world where most people can barely afford their econoboxes and the people that do mods stop at bolt-ons and replace the engine if something goes wrong. Heck, before KZbin I didn't even know they made stronger aftermarket internals for production engines, or that a damaged head can be resurfaced by a machinists shop. Where would I be able to learn about these things, mechanics school? That place would say don't touch anything that's not oem because "the factory that made the engine knows best and makes the best possible parts to work with the engine they made" or some nonsense like that. Plus that I can't stand being in school and forced to do stuff that I don't want, glad that's over. Like this I can enjoy the videos and learn things along the way. It's not like I can go to a track and ask the owners of custom built cars what they did to their cars and hang around at their shop to learn since this sort of stuff doesn't happen around here, I've never seen a dragstrip aside from KZbin. And even if there were such a thing around, it would be nothing like this level, just a regular tuning shop, what would be the chance they would let a random nobody hang around and learn about what they do. Plus my health and other things like earning a living wouldn't allow me to be there nearly as much as I would like. So yeah, I am grateful to all these people that take the time to show others how they build custom cars, share tips and tricks and teach others how they do things. And not just in cars but in many other subjects, like electronics, computers, mechanics and many more. I learned more from BigClive and Ave than I did getting my electrician diploma. And the likes of Finnegan's garage, motortrend before they went off KZbin, Brent from Pfi speed, Jeremy at Fasterproms and so many more I learned things from, these being a small fraction of the channels I watch, it would take ages to list them all. Years of watching things on KZbin also greatly helped with my English as it is not my native language and without this, games and spending my time figuring out how to use computers, after finishing school I know that I wouldn't of been able to even piece together sentences, like almost all of my schoolmates, unless you have your own activity that makes you deal with English or really wish to learn it, what they do in school is literally useless as almost no one actually learns anything. Forcing people to learn about a language just because "you have to if you want to pass" does not work. They should motivate the students by telling them something like "don't you want to be able to communicate with people anywhere you go, or watch movies without needing subtitles, what if there aren't any for that thing you wan to see, etc, well if you do you should look into this" being fluent and speaking correctly in a foreign language is a really hard thing to achieve, but you don't need that to understand people, communicate and get great usefulness out of it. I got extremely carried away but don't feel like deleting most of this comment as it took a long time to write and has a meaning. But yeah, Thanks for making it possible to see these things without being there, someone from the other side of the globe appreciates it, seeing some of these things is really inspiring. Waiting to see your 4 rotor come to life Rob.

It always amazes me how one can know how to make a build like this. How to come up with all the customizations, figure out how to design everything to fit properly, get the desired outputs, engine sounds, gearbox timings, pressure values, cable and tube management, body work. Just making everything fit and work as you imagined it. You need to know everything there is to know about every part and details of a car and engine, every limit and possibility etc to know exactly how to make everything work. There's nothing conventional about this. It's all about pushing boundaries and think outside the box. Anything is possible if you know the ways around it, and to know that shit blows my mind. It's like science and chemistry. It's hard enough as it is and not all people can be a scientist or lab professor. And after years and years of learning, understanding and research you can start manipulate the elements when you know all the do's and dont's like what goes into what and with what or should work with some changing to the variables, what's too much or too little, break everything down and apart to explain every step of a reaction process from one form to another like it's common knowledge... To me builds like this is like that 1% shit what has no drawing where everything is logically planned out for anyone to follow if you just have the tools, materials and handy skills. Like building a house, anyone can do it with a little experience with building. But this is not by the book like "How to build a 1000 hp drift car". This is your imagination and how to apply it in reality using extreme means. This level of customization is like that difficulty in games where it says you won't make it unless you're a professional pro xD Not just live for it, but so addicted that a social life outside the community doesn't exist. Where the regular pro goes "That's taking it too far man". I mean I've seen custom builds with jet engines like how the hell does anyone come up with that idea and then how to make it work in a street car?? You pretty much need to make all the part yourself because you can't find those when shopping for car parts online or at the store.

Yeah more torque but never be Stronger this Rotor engines you servecing every 2000miles all Hardware need to repair .... the Price of this High Rotating rpm and more than 20PSI are critical ...20PSI is nothing for a 2Jz or Audi 5Zylinder Turbo they are Laughing and scream give me more

[@buddylee19082]

Idk why but I was expecting this to make more torque? Regardless 950hp/650tq to the wheels is absolutely INSANE! And anyone questioning Rob's choice in turbo size [in his 4-rotor] simply doesn't understand the volume of air being pumped out of a 4-rotor engine. And the graph proves it! Just look at how beautiful that curve is!? Even with that dinner-plate-sized turbo! WOW!!! Rotary FTMFW!!!

Not even close. It has done nothing to prove it's self and the drivability is trash hesitating at part throttle.

[@sweissco345]

Now I’m super hyped for the 4 rotor

[@amaulana090]

I sorta wonder why the exhausts are in three different locations... I remember seeing some N/A engines with intricate and curvy exhaust headers to make the length from cylinder to exhaust tip to be the same for all cylinders. Why ignore that for this build? Is it less useful in forced induction or rotaries?

[@joshsmith6208]

forced induction doesn't care about header length because the exhaust gasses are just being forced out by the boost pressure. NA engines rely on the scavenging effect to help pull the exhaust out of the cylinders. the equal length header tubes keeps the cylinder all timed correctly so that exhaust gasses flowing out from one cylinder will scavenge, or help pull the exhaust gasses out of the next cylinder in that bank to fire.
