Seeing I cant start my own threads Im borrowing this one.
Has anyone seen one of Keisler's lfx swaps? I noticed the majority of people posting in swap threads related to him are brand new users that have never started a thread or posted on anything other than that build thread.
It does seem like hes done some stuff in the miata community but outside of that there isnt much to be found.

I follow your channel and have watched your videos. Andrew is about to have a media blitz for the swap and I’ve bought one and am shopping for a clean car to swap. Going to be a track car.

Awesome! You're going to love it. I haven't had a chance to get it on track yet, but on mountain roads it is unreal.

Yeah i've spoken to a few folks with this swap and all are happy. For reference, my Spec E46 race car on Toyo RRs at a local track does a 1:24 while an LFX RX does a 1:17 on R7s. The tire is worth 2 secs on this track/direction but given i can build this car for half the price of my SE46 it's a no brainer for a fun track car that should demolish more expensive cars. I'm going for the shock factor and the fact that everything on it is cheap. A rebuilt M54 for my bmw was right around $8k while the LFX can be had under $1k then i had new seals and go.

Andrew seems like a good guy but you never know.
Anyways Im purchasing from Andrew. I'll post how things turn out. The thing that had me worried is everyone posting were new members and had less than 10 posts.
I realize I fit that profile also. Ive been an rx7club.com member for 10 to 15 years under the same name as here.

Or they end up bailing in short order, never being heard from again, etc. Because this is not the typical direction that an actual RX8 enthusiast is likely to take. It doesn’t really fit in to anything more than being a play race car with no real competition class to run in. I’ve seen a lot of V8 FDs come and go over my lifetime for the same reason.

I’m not an actual RX8 enthusiast but I respect the chassis for what it offers. The LFX swap will slot into all sorts of classes. We plan on using one car for WRL and AER while another is going into Nasa TT or ST.
the V6 swap is great because you’re not overpowering the car and classing it too high.
the chassis’s are plentiful and cheap and yeah I get that people don’t like motor swaps but it helps keep these cars relevant.

I apologize for bailing guys. Team was right...an emergency occurred and I didn’t want the thread to get full off non related information. Still I should have explained.
During this interim I have done a fair amount of research. Driven some others types of cars I thought would be interesting ... including a backdraft cobra
but I always find myself coming back to the rx8 for one reason or the other.
Meanwhile I did place a Cobb tune on my Porsche Macan s and do some intake and suspension work....this is a pretty good platform guys...especially for a family hauler! But I digress...
My build is going to happen, no later than the summer of 2020. If at all possible (space wise) it will be forced induced. Supercharger preferred. Seems with the 2012 and later lfx engine you can’t really get to the power range I want ( at least 350 to the wheels but less than 400). It will be a DD with hpde fun. Have not decided on an s1 or s2 yet. That decision will reveal itself.
As soon as Christmas is over I will be actively looking for a car. Again my apologies.

He’s an SC fanboi though. Ok on a torquey, lowerer revving engine, but the e-shaft hp requirement to turn a blower capable of feeding enough air at high rpm on a rotary just eats up way too much torque output. Which it takes power to push a turbine too, but it’s way more efficient. So a lot more engine stress at the same output level with an SC than turbo for a rotary engine. Once I came to understand this reality, all my desire to ever choose SC over turbo for one was lost entirely. When you look at the short lever arm an e-shaft has compared to a crankshaft and also there being less power cycle pulses in larger output magnitude over a 6+ cylinder reciprocating engine then it starts to make more sense why that is.

Appreciate the invite Brettus.... just may take you up on that👍.
Team hit it on the head....guess I am just old school? Nothing wrong with that but I am in total agreement that a turbo is more efficient ...therefore more capable.
Someone that really knows what they are doing can build a turbo system with no lag and have an envious torque curve. Brettus for one. So.....hold on to your hats.....
I haven’t ruled out a turbo system, but I do prefer the sc at my desired power level. Room may dictate the decision. We will see.
I also do plan for a water meth system....since I will only be doing hpde stuff. I like what it offers direct injection engines.
Plan on setting up the suspension like my old car with front / rear bars ( racing beats) / end links and the kw3 coilovers.
Wouldn’t it be cool if I could get one of the custom car garages on tv to do something with it? Think I would like the suicide doors open like a Lamborghini?
But speaking of power I have seen a 600+ rwhp lfx turbo in a Camaro. It also sounded just wicked good!
Guys this will be my last build...lot has happened in my life and I am now 70 yrs old. Realistically speaking...well time catches up with everyone. Even though I am in great shape... still do may thai 3 times a week etc....I am slowing down. So this build I really want to do it better than right. The car will be left for my kids/ grandkids and when they look at it I want it to be an example of doing your best.
So hold on all...can’t wait to get this party started!

20 b build will be just awesome man....will follow that one.
Been in contact with Keisler Automotive ( Andrew), and he is moving his shop to Colorado from Tennessee but he can still do turn key builds.
Basically room does become an issue especially when you want a/c... which I do!
I asked if the lf3 would fit and he said “no”. BUT he also reminded me that the lxf engine is a dual fuel set up
and with e85, cams, and others mods I could get close to 350 rwhp NA and with a centrifugal s/c at 10 lbs boost/e85 set up he has seen many engines hit the 475 range! Whoa ..don’t want that much.
No room for turbos unless you go with a rear system close to the exhaust tip.
The centrifugal sc will not have the low end boost that one normally expects from an sc engine but I have to remember I already would have ( without any boost) nearly 300 ft lbs of torque in a car that the weight would be approx 2900 lbs and with a diff ratio of 3.91!
This is getting a little exciting!
For those that haven’t visit his internet site... he lays it out what a great chassis this car has and why it should not be forgotten.

OD, I know it is still several hours away, but you are welcome to come up to Chattanooga and drive mine. It honestly has the right power for fun mountain road driving. As we all know, its not just peak numbers, but the overall powerband. I will say that on-ramps and highway blasts could definitely be more entertaining with forced induction. I have spent months trying to workout turbos on this thing, but there would really need to be changes to the car that would effect it being a comfortable daily driver. With a ported intake, tb, and e85 you can have a pretty good power to weight ratio I would say.
