K24 Swapped and Supercharged 2006 Lotus Elise

Do you want to know what fast is?  Strap yourself into a 2006 Lotus Elise with a Honda K24 Engine Swap and a Supercharger installed.

Not to sure how much interest there is for something like this on k20a but in case you are interested or know someone that is interested. I am selling my VERY prepared K24 swapped (and supercharged) 2006 Lotus Elise.

The thread on LotusTalk can be found here:

- 2006 Lotus Elise, Solar Yellow, a little less than 22k miles
- Sport Pack, and I believe touring pack.
- Hardtop
- 2 Owners, Clean Carfax (No Accidents)

After going through a few iterations of powertrains I settled on the (relatively) stock K24A2 + blower, I am very happy with this choice in the end, and the recommendation was largely the brainchild of Derek of Hondata (the guy knows his stuff!).
- Stock K24A2 from a Manual TSX with mid 50k for mileage
- K20A2 VTC gear for added range on intake cam timing (although in practice it doesn’t need much)
- Moroso deep sump trap door oil pan (Eliminates oil starvation)
- Magnum Powers MPx90 blower on DC5 JRSC manifold with a 3.25” pulley making ~14psi of boost
- Skunk2 74mm throttle body (cable driven ;) )
- MercRacing second generation Bell “drop-in” intercooler
- BOE heat exchangers (same as Rev400 kit) in the passenger side rear with fans.
- Bosch Intercooler system pump
- Lotus Sport 3-pass upgraded aluminum radiator (no more blown stock radiators!)

- Innovative Mounts Honda K-Series swap mounts – 75A, 3 mount kit.
- Innovative Mounts shift mechanism
- Innovative Mounts Lotus K-Series Gas Pedal, Throttle Cable, and Bracket
- Innovative Mounts Louts K-Series Clutch Line
- Custom wiring for K-Series into Federal S2 Elise/Exige (I am one of the few people that actually understand these and do it for others).
- Hondata Dash Converter box to use Stock dash with Hondata Kpro ECU.
- Hondata KPro v2 ECU
- Custom dyno tune


The car was originally setup for E85 and clearly has the capacity to do so. I did convert it back to 93 octane, simply to broaden the buyer market since I know many don’t have E85 readily available. However if the buyer wants to convert back for some added power and safety realize the capacity is all there it just takes a new tune.
- In-tank Walbro 255hp
- Integrated engineering surge tank with built-in Bosch 044 fuel pump (Eliminates fuel starvation)
- DW 1300cc fuel injectors
- Hybrid Racing Fuel Rail
- Aeromotive fuel pressure regulator
- All custom lines for return fuel system

- 3” Intake with Vibrant velocity stack filter
- Custom equal length exhaust header with V-banded collector. Made from all quality parts sourced from ASP (well known header builder in the Honda community). Ceramic coated black.
- Custom exhaust with 3” straight-through Magnaflow muffler. I am also including a pricey but higher quality 3.5” Borla XR series muffler with stainless packing material. I never got around to putting it on but the goal with the Borla muffler is the quietest system with the highest flow.

- K20A2 6-speed.
- Complete new forged close ratio 6-speed semi-helical cut gear set from Gear-X with “longer” 6th.
- Synchrotech carbon lined synchro set.
- Transmission build performed by King Motorsports in March of 2013 now with about 2k miles on it.
- M-Factory mechanical (helical) Limited Slip Differential
- Clutch Masters FX350 clutch
- Clutch Masters 11# flywheel
- SCC shift cable replacement (no more broken stock cables!)

- DBA4000 rotors on all 4 corners
- Carbotech XP10 pads on all 4 corners
- Extra set of Carbotech Bobcat (Street) pads
- Motul RBF600 brake fluid

- BOE (Full) toelink replacements.
- Nitron 46mm Race Pro Singles on 450/600 springs. While these are not the big dollar 3-ways, don’t confuse these for the regular “Nitron Singles”. The 46mm Race Pros are derived from the Race series dampers and are far more desired as a performance damper.
- Stock front sway bar drilled for one extra stiffer adjustment point. (I actually had a BWR bar on here but it induced far more understeer than desired and going back to stock balanced everything back out)
- V2 steering arms and V2 shims for added camber up front
- Corner balanced and aligned
- Dunlop Z1 Star Spec tires

- Radium modular clam removal kit
- S111 rear diffusor exhaust hole block off plate. Diffusor powdercoated black.
- DZUS quarter turn hardware full set (Replaces all diffusor and undertray little bolts for faster access)
- Removed stock plastic side scoop grates for as much airflow as possible. They come with the car if you want to put them back on.
- Removed stock battery and replaced with BOE battery kit and lightweight Odessey PC625 battery.
- Sector111 “Booty” trunk organizer
- Sector111 “DarthHolder” cup holder

Interior Condtion:
Generally in good shape. The leather only shows very minor wear with no tears or anything. If I recall it has a special lotus trim shop pattern on the leather which is a nice touch. There are few minor scratches here and there but nothing serious. The most wear is seen on the driver side plastic sill. Also of note is that due to the swap with the K20A2 transmission the center console cover is not installed so that there is enough room to move the shifter into reverse with more ease. The stock console does come with it if the next owner wants to trim things around to make it fit. I would give the interior a 8 out of 10. See the pictures below.

Exterior condition:
The exterior is in decent shape and the paint/clearcoat is in good shape due to having few miles and being stored the vast majority of its life. There is no fading what-to-ever. The exterior shows does show wear than the interior with the front of the car showing the most simply due to catching the brunt of all the rocks, bumps, etc. There are little scrapes, marks, and occasional chips here or there that are consistent with a car of its age. The wheels are in good shape but all have one minor rock chip. The biggest issues with the exterior are:
1) There is minor fiberglass damage on the bottom edges at the front from the car being so low. Its pretty small and you really dont notice it unless you have your head on the ground.
2) On the underbody of the car at the rear on both sides there is a crack about 2-3 inches long on the side sill. You can not see it from the side or even the bottom unless the diffusor/undertray panel is removed. I am guessing the previous owner took the car to a crappy oil change place that thought they could simply jack the car up at the rear from the “pinch weld”. The previous owner did not disclose this to me, but I am disclosing it to the next owner. Its not a huge deal as its not structural, not visible and hasn’t spread. But it is something to be aware of.
3) The original star shield did its job of protecting the paint but is getting old and like most all Elise/Exige with the original star sheild is showing some dirt around the edges and really should be replaced.
Overall the car looks great from a few feet away as the paint is in good shape, the body is straight, etc. Just when you get up close you start to see the car showing its age. I would give the exterior a 6 maybe 7 out of 10. See the pictures below.

Mechanical Condition:
Mechanically the car is sound. No real issues to report. The biggest thing to note is that due to the swap the car does NOT have AC. The performance is downright staggering. It makes a stock Elise/Exige seem tame and makes “normal” sports cars seem like a honda civic. I am sure my Elise is faster than my M3 at half throttle and makes it seem like it transitions like a school bus. The car was originally tuned for E85 where it made 383whp and 278 ft. lbs of torque at the wheels. I retuned the car for standard 93 octane pump gas and I am guessing it probably makes somewhere between 350-360whp and just shy of 260 ft. lbs of torque at the wheels. That type of power weighing it at just 2000 pounds is very fast! Even though the Elise/Exige are not known to be good drag racers, I once took my car to the drag strip just to see what it would do and on E85 and regular street tires it went low, low 11s and could have dipped into the 10s with a bit more seat time I’ll bet! Also remember that because the car has a positive displacement blower the power is there immediately with zero lag what-so-ever. Between the powertrain, suspension, brakes, etc. everything about the car is very immediate and raw. Its hard to truly appreciate it until you drive it.

Price and Closing:
Asking $40,000.
Truthfully considering what you are getting that is a steal. Stock, Clean Carfax, 2 owner, 2006 , Sport pack, Hardtop, Elises, with 22k miles are worth around 30k. Then consider all of the money, time, effort required to get a car into the current state. I don’t even want to think about the total amount of money and time invested. It’s hard enough to simply obtain the parts, and I’m not sure if any Honda swapped Federal S2 Elise/Exige have ever gone up for sale. Ask anyone who has successfully completed a swap like this how much time, money and effort goes into it ;)

Ideally I would like to sell the car to a fellow Lotus Enthusiast that is a DIYer. It really was my baby for the past few years and I would love to know its going to a good home.

The car is located in a suburb of Milwaukee, WI.
I would prefer email/text contact as I am constantly busy. If you are going to call get a hold of me first by email so we can coordinate a time.
