I have planned on making a build thread for both of my Elises, as they are both ridiculous in their own right. Here's one of them.
So I had been in the market for an Elige to build something stupid fast with, preferably something already turbocharged to save me a bit of trouble. Even better k swapped to save the trouble of sorting that out, although I have no doubt stupid power would be doable on a 2zz I think the k20 would be a better platform.
The Kings Performance Lotus came up for sale in late June 2015, which I only had to sleep on the thought of buying it for a day before deciding to put in a deposit. A bit more sorted than I had intended to buy, but certainly on the right track and well in the direction I was wanting to go with the build.
The goal is to make a killer street car. Something close to an end all. To have a Lotus keep pace with the Supras, Corvettes, Vipers, Gallardos and GTRs at drag and roll race, and dominate them and everything else when corners are added to the mix.
The plan is to run this car at national level drag and roll race events, e.g. TX2k and Texas Mile. Locally I will track and autocross the car because why not. Depending on how the car behaves I may run it at higher level road course and autocross events. I will also probably daily the car in the warm months
This is not my first rodeo.
There are a lot of videos, forum threads, etc on this car already.
WORLD’S FASTEST Lotus Elise K20 Turbo - Honda-Tech
Some controversy there over a “drag lotus” or “that’s not an Elise because it makes too much power or has a k20 or whatever”. To which I say, an Elise doesn’t come with the 240whp a VF2 or Rev300 makes so is that not really an Elise either? How about a Rev400? Where is the line drawn? Frankly I don’t care. I put some 35k miles on an NA 05, I think the VF2 was a marked improvement. Some more power on top of that even better. Better coilovers and steering arms better yet. Ditch the fragile C64 trans, more confidence in the car, an improvement in of itself. Etc etc One toe link failure or oil starve is all that you need to figure out beyond doubt the Elise could use improvements.
My goals are above.
Constructive comments and suggestions for meeting these goals are appreciated and will be taken under advisement.
Before I start adding my contributions to the car, here is the build list as far as I know.

Between the last two owners, I would guess there is near or over 80k in the build, and I am sure I will pay my dues as well.
Issues to address:
K20a2 AC compressor does not fit due to clearance with firewall, will see about a smaller compressor, or fabricating a bracket
Inadequate amount of rubber. Until I decide to go all out in a certain direction, this is what I think will be most appropriate for one tire setup being used for everything and being capable of driving to and from events like a true street car.
I have on order
front Team Dynamics 1.2 which will run 225/45r15 Toyo R888
rear Bogart 3 piece 18x12.5 and 335/30r18 Toyo R888
Both powder coated black
Plan is to cut the rear fenders as needed and add flares (depends how I feel about the rubber sticking out)
Easy handling improvements:
V2arms or similar and proper alignment and corner balance and lower down to ~118/123 f/r ride height or as the geometry allows.
possibly buy a set of 550lb front 800lb rear springs for track/autocross
Tune for E85. Pulled the 1650cc injectors from my SSM car and swapping those for the 1200cc that were in the car from King’s. 1650s were oversized in the SSM car so it works out. Waiting to hear from Kings on how it comes out but the expectation is well over 700whp on Mustang dyno. The ECU will also hold a map for 93 pump gas at around 500whp which may be more manageable for races that involve corners.
I have some concerns about the adequacy of the charge cooling system when tasked with road course duty. In a forum post bbs350z says that it had no problem keeping IATs within 10c of ambient in Arizona heat, and Fernando, the owner of the car with King’s Performance told me he had no problems with Florida heat either, but he never road coursed the car and used ice in the reservoir for very low temps when he drag raced. Maybe (hopefully) it’s fine, more experimentation needed.
I have already ordered a second set of trunk mounts for my comically huge maximum allowance SSM wing to move it between my 100% prepared SSM car and this car which I may run in XP for kicks and grins. Will probably move my 275 A7s between cars also.
Probably will move the sparco wheel to my SSM car and the momo team from it to this car.
Have a few other ideas but need more experimentation.
