@chrishuyler3580 3 года назад

I agree, he's building his rotary the way I would. I haven't gone turbo with mine yet but my N/A build shares a lot of similarities and if/when I go turbo, this is how it's gonna get done. Keep the primary injectors for drive-ability, small quick spooling turbo, clean up all the emissions stuff, etc.

@dubbleA100 3 года назад

The best part of Rotaries besides the compact block is that we can make them flow air like a V6 just by porting. If you want to make torque on a rotary just change your turbo setup or add spray, the V8 guys run turbo and nos so why not us. Also don't forget that back in the day the banned Full Peripheral port motors because of the unfair amount of power they were making for their classes ☝🏿 Don't sleep on Rotaries

@ryanatha3555 3 года назад

agreed it's blasphemy

@josephsamsor1698 3 года назад

Jon athan a k series is actually a really good swap. It keeps the driving dynamics close to factory and the engines are just perfect for horsepower and keeping the weight distribution right.

@Shiftheads 3 года назад

@@josephsamsor1698 You do realize a ls weighs almost the same and sits far back near firewall so really you have great weight distribution and a reliable engine with parts that are dirt cheap. I get wanting to keep the car true to the heritage but to say a LS would be worse in the car just isn't true

@josephsamsor1698 3 года назад

Intoeverything I never said it’s worse. The person I was speaking too clearly thought it was a bad option, even though it’s a great option in about every way. For me personally, a well built k series is cooler in a rx7 than an ls but both are good. Personally I’d want to stay rotary since it’s such an expensive car in the first place.

@israelcardona5170 3 года назад

They say that just in case (which it will) the motor gives out because of lack of balancing and poor measurements on side seals.

@ztyhurst 3 года назад

That's on them... The poor little FD should not be punished with an ls if they can't build a rotary correctly.

@minilurk11 3 года назад

@@israelcardona5170 how do you know it wasnt balanced? Also the side seals were measured fine. Rotaries can and will last

@israelcardona5170 3 года назад

@@minilurk11 never mentioned in the video just like the corrosion on the EVO block was never mentioned either, they didn't use same rotar's with the crank and so that's a no, side seals on RX8 Rotar's need to be properly measured and not just go by feel like they did in the video, also changing out the Flywheel without changing the front counterweight is going to be its big down fall especially they're going to rev it to 10,000 rpm like they said they will...

@patw9175 3 года назад

Not to be all hail-corporate but after Project Farm's oil showdown I'll probably be going with Valvoline from now on. They support Speed Academy and since I've been looking into what makes one oil different from another it seems like a way better value to what I normally put in my cars and motorcycle (mobile 1).

Bring on the modern FD build. It's good to see the platform "mature". I'm curious about the premix ratio, 100:1? Don't do an LS swap, do a C6 build now that those are cheap enough.

@RGHTBrainDesignDrive 3 года назад

Guys, that EFR7670 0.92 A/R will top out before 6750 RPM as EMAP starts to overwhelm it. You'll be running a TON of backpressure by 10k RPM. Realistically your needs would have been best met by an EFR 8374/8474 with an external wastegated (dual 40 or 44mm) on the 1.05 A/R housing. For anyone reading this, larger porting = more sensitive to backpressure. Larger turbine wheels are necessary comparatively to a reciprocating engine.

Not bad, I guess 400WHP is pretty much the limit of the turbo and response is stock-like?

@brianawd 3 года назад

aDaWaN Lucky7 made 450whp on the same turbo with a street port. I would say response is better then stock

@kylehufford9645 3 года назад

Something that I see, You mentioned the Phelonic spacers keeping the heat out of the fuel rail which is very smart. However then your routing your fuel line right on top of the engine. I would suggest heat wrapping the Fuel Lines or trying to re route them so they aren't heat soaking on top of the engine. Just my 2 Cents. Love his build series! I can't wait to see this engine running in the car!
