  • Build a 4 rotor drag car and make it work I guarantee you your channel will blow up big. Plus that's really exciting unlike whatever that is you got going on because you're just spending mom and dad's money on BS. You went in that thing because that shaft is very expensive.

  • Us Puertoricans the kings of the rotary engine who you don't like to acknowledge very much, we make upwards of 1,600hp with a 13b. But you build a nice car for what it is.

  • I just stopped by to say that Ken Block currently has (arguably) one of the very best performance cars that's ever existed on this planet and a team of tuners that knows it thoroughly so you almost had no chance of truly beating him..now that I've gotten that out let me say what I actually wanted to say which is that no one with an opinion that matters gives a FUQ because your 4-R car IS (not arguably) the baddest car currently circulating the internet and I mean, does anything else really matter..that's rhetorical but I'll assist with a "NO"

I'm not a wealthy guy at all but wanted to contribute to the RX7 and now I just feel ripped off. You probably won't even see this and again my message will fall on deaf ears, I'm still $50 down and no shirt! :( FML. Has anybody else bought a shirt and not yet received? (Bought in October)

  • The 2jzgte vvti gtus is going back to 13b rotary! www.mazdaforum.com/forum/mazda-rx-7-33/joe-maddox-super-rare-1-100-1989-fc3s-gtus-rx7-2jz-gte-vvti-build-43602/ I have found and saved the rarest Mazda FC RX7 ever made! Now this car is rare. Really rare! Let me break this down really quick... Ever heard of the rare 100 GTUs rx7s? Only 40 have ever been claimed and only 15 are confirmed at the time of this posting! Here are the rarest rx7 FC3S models: 1500 10AE Turbo models 1400 infini 1000 winning limited 150 final edition convertible 100 GTUs... out of that 100 they made three color options: red on black black on black white on blue There was only 100 GTUs models created between 1989 and 1991. If you own one of these rare models sign your car up to the registry list here on any of the rotary forums! There are rumors about a restamped GTUs model... The entire origins GTUs owners thread on the rx7club was modified, icemarks claims deleted, registry list changed to have a confirmed section and the mods agree there are not enough GTUs models to have the restamped. If you want the full story behind the restamped models: www.mazdaforum.com/forum/mazda-rx-7-33/restamped-mazda-rx7-45926/ www.rx7club.com/2nd-generation-non-technical-pictures-198/restamped-mazda-rx7-1148475/ If you have a real GTUs you can register it here: www.mazdaforum.com/forum/mazda-rx-7-33/official-mazda-rx7-gtus-owners-club-thread-44477/ www.rx7club.com/2nd-generation-specific-1986-1992-17/mazda-rx7-gtus-1148362/

    Lifted_AboveLifted_Above18 päivää sitten
  • Lol you act like 1400 hp is a lot but there are sbe ls engines making way more hp and lasting longer than your engine. And valvoline is just a oil. Nothing in it makes it better than any other oil. Your oil didn’t protect your engine when the pump went out the oil filter did you clown

  • What would it dyno naturally aspirated? Is a 4 rotor practical without turbo? Considering a rotary for a boat but don't want to compromise integrity by having power adder(turbo, supercharger etc). My Dad was a Mazda mechanic his whole life, I inherited his 72 RX2 2 dr SCCA spec race car. The work you do with the Rotary really has brought alot of attention to it. Nowadays everyone with youtube is an expert till you say the words "12A" . I get alot of confused faces when they ask what engine is in my "Opal" ... LoL

Both before and after that experience I have only ever changed oil. I tell you this to impress upon you-I did not expect to watch this video through. But I did. Really, inexplicably fascinating.

  • Rob nice rotary. Since you're going to rebuild it you should modify the rotor housings to solve one of the major flaws in rotary engines. The loss of compression through the primary spark plug hole. Weld some material into the hole and make it into a slot thats no wider than the apex seal, then get some custom plugs that when installed they line up with the slots. You would be surprised how much compression is lost through that opening especially at boost or how much cxhaust contamination you have depending on port timing. You would probably have a substantial hp gain just from that modification. If there is a problem with ignition, I haveca cure for that as well from my years of working on rotories from 1976-1986. Lost count on how many I built over those years but my guess would be several hundred. Good luck. I still think the one piece carbon apex seals were a good design. In all of the motors I built and raced, I only had one fail, but saw many two piece fail.
