Curious what something like this usually sells for..... I'd like to say I'm interested, but I have a feeling these things are still a ways out of my price range without a drivetrain.
5.3 with paddles would be cool, but I personally prefer an old school manual even in a supercar replica or kit car, its so hard to find true 6-speeds on the actual exotics these days (I read less than 1 percent of late model Lamborghini and Ferrari produced with manual trans now)...... I'd love a manual Porsche transaxle in this chassis with LS9 (or LS7 with a twin turbo kit). It would also be quite cool to build a higher revving naturally aspirated LSx motor with individual throttle bodies and either 180 degree headers or a Lingenfelter flat plane crank kit to try and capture that higher RPM, NA, snappy throttle response sound and feel that exotics and other F1 inspired cars tend to have. I know actual Lambo owners would find it horrifying, but I think it might be an overall better car than the original (would certainly be cheaper to maintain and get better mpg, haha!)
TNH, you got me all excited with the idea of a Lingenfelter flat plane crank kit so I called my buddy Jeff there to order one. He told me that they did make just one as a R&D project but it was way too fragile for any intended use, and there were no plans whatsoever to develop and/or market it.
I'm sorry, I hate spreading false info and I shouldn't have been repeating what I heard about these 'kits' without looking further into it. I just went back and re read a lot of the info I had on the LPE flat plane project after seeing your post here, and you are right, it looks like they were showing off more of a one off type project, although I am still a little confused about it because I have seen 'build threads' on LS swap type forums where people have mentioned the exact cost of these kits (or just the cranks) and some have even claimed to have them already in their possession....although I could be the victim of good old fashion internet lying on those ones. After re-reading I do see some people bringing up their flat plane crank projects made by other manufacturers but being discussed in the Lingenfelter threads which I mistakenly thought were parts bought directly from LPE. I also remember seeing (or thought I remember Lingenfelter talking about offering these to customers years ago on their own website. Here it is.....very short and vague, but they mention something about building it for customers and he sent him a PM regarding cost, back in 2011 too....

I also saw a 'complaint thread' basically about a bunch of people saying the LPE setup was too expensive "just to get a little bit higher revving engine and a closer to exotic sound'. .....unless they were talking about the cost of the one off setup after hearing whatever that was from LPE and assumed they were talking about kits?? I was also assuming there was a kit in the works because I remember seeing them discussing and showing pics of a flat plane crank set up in motors that were being put in street cars, as well as multiple builds that they said (at least back then anyway) would all be getting dyno'd with the flat plane crank as if they were getting ready to run these things off an assembly line or something.
well darn, I'm sorry I was wrong about that. If you do really want a flat plane set up, you may want to google and read everything you can on the threads related to the LPE stuff because there is a lot of talk from people claiming to have the proper valve trains for this as well as custom cranks (and I'm hearing prices as ridiculous and probably BS as $750, others at $1,500-5,0000 and even a few people saying $12k. There was a thread on the SLC race car builder forum where someone was claiming to have some pretty serious components for an LSx based flat plane setup.
Now I'm really curious how real any of this is other than the one LPE put up videos of. There are vendors posting in the LPE threads I read claiming to have cranks for LSx's or claiming that they could easily make them for customers if anyone wanted one.... so it may be that some companies are offering this sort of thing publicly.
EDIT: I'm still trying to find some links to make me look less bad, haha....I just realized a true bone head mistake of mine, I kept seeing 'flat plane crank for real street car' headlines during google searches and mistakenly thought they were referring to 'real street carS', as in cars ran on the street by customers, not their one off car that runs the 'real street' class, lol.
Edit again: check out this thread....that guys first post makes it sound like not only does LPE offer a flat plane crank set up for the LSx, but everyone knows it and its way too overpriced. I just find it strange to see anyone talking about LPE in that way if they didn't offer that product or at least say they were going to offer it at some point.
