Last 111, First Street Legal K20 Swap? (Part 3)

Last 111, First Street Legal K20 Swap? (Part 3)

It’s been a while since we had an update on this car and a lot of people were starting to wonder what happened to it. Between the many obstacles to overcome, developing some custom parts, going back and forth on decisions, the owner of the car (and myself) having two having kids, this became a sideline project in the shop. Our usual chats shifted from the K20 swap to sharing our experiences raising two young children. Although progress was made slowly throughout, I wanted Part 3 to be the final part of the blog.

Restoring an Evora 400

On a Saturday evening earlier this year, I stopped by the shop and unexpectedly saw an Evora in our parking lot that looked like it had been in an accident. I later received an email confirming this, and it had been towed in for an evaluation.

It’s been over 3 years since I put the Honda K24 into our Lotus Exige and it was the first car that I made an engine harness for. Although the harness was reliable and never gave me any issues, I felt that my harness building skills have improved much since then. What I really wanted to do was get rid of all of the unused wiring and the mess under the dash.

Trackspec's K24 Exige- Global Time Attack

A few months ago, we decided to register for this year’s 2021 Global Time Attack and Super Lap Battle Finals at Buttonwillow. The Exige wasn’t built for time attack, but we thought it would be a fun place to compete and see how capable the Lotus with a K-series really is; even if it is heavily outgunned in its class (because of the rule set, the car falls into Limited, a class that normally sees cars with forced induction engine setups making well over 600whp). We decided to set our own goal of a sub 1:50 lap, which may be the first naturally aspirated Elige to do so. The best time this car had done previously at Buttonwillow 13CW was a 1:51.7 on Falken RT660s.

With the 25 Hours of Thunderhill postponed to 2021 (thanks, COVID) the final race weekend of the year took place at Buttonwillow in the form of a double header, Super Touring sprint racing and a 3 hour and 15 minute night endurance race as part of the Western Racing Endurance Racing Championships. We were able to use the month of September to properly prep both the Lotus Exige and the E36 BMW M3.

If you grew up in the 90s and were into cars, then you’ve heard of the Honda B-series engine and how amazing it was. It was the “hot rod” engine of its time and my gateway into modifying cars. The planning, researching, parts sourcing, building, and then seeing how it improved the car’s performance is what got me hooked. In the early 2000’s, Honda came out with something even better..

At the last two-day track day at Buttonwillow with Speed Ventures, shifting in the Exige started to get notchy. It would sometimes be difficult to get into gear, but we kept driving it. By the last session of the day, we were not able to get the car into gear after pulling off into paddock. If the engine was off, it would go into all gears, so we suspected it to be a failed clutch that was not fully disengaging...

Fuel starvation is a well known problem with this platform. It’s mostly noticeable on long left hand corners because the fuel pick up is on the left side of the tank. It’s typically not an issue if I keep the fuel tank full, but every time our got down to about 70%, it would starve. This can cause a lean condition and be harmful to the engine, especially with forced induction.

This past Monday, June 24, we decided to take a team day-off to go to the track with Golden Gate Lotus Club. In addition to drives, meets, and fun outings, GGLC hosts great track & autocross events. Only three run groups, so you get SEVEN sessions! Not to mention, they always offer snacks, coffee, fruits, and sometimes even lunch!

It’s no secret that Reverie makes high quality (wind tunnel tested) aero parts for the Eliges and I’ve always liked their front splitter design. Although Reverie’s mounting solution works great and is solid, I decided to attach the splitter directly to the chassis, and not to the front clam. My reason for this is so that I can easily remove the front clam without having to remove the splitter first. This did require cutting the front lower portion of it so that it could just rest on top of the splitter…

When we first acquired the Exige, Victoria and I had multiple conversations about what we wanted to do with it. Our original plan was to keep it street-legal, and just use it for canyon driving and the occasional HPDE events. I knew that it would have a much higher resale value if it was kept street-legal. Plus, being that this is our first Lotus, we liked the idea of being able to take it out every now and then. We also wanted to take it on long road trips and enjoy some of the fun back roads we have here in California. …Well, that idea didn’t last too long.
