K20C4 Engine Swapped Civic Si Gets Dyno Tuned

The wait is finally over. After a year in the making, my K20C4 swapped 10th gen Civic Si gets dyno tuned. There were some initial issues, but the car put down some solid numbers in the end. The car is finally complete and ready to hit the track. Many more videos and information to come on the swap and other car content.

This build is more important than a lot of people know. When people do these builds, they are paving the way for us in the future with these 10th and 11th gen Si’s. Thank you so much for sharing your journey.

[@drivenlowkey2437]

All that hard work paid off man! The 2.0t sounds way better than the L15! Makes me want to k swap my FK7 😂.

[@OrangeChicken417]

Awesome build, but man these new K Series/L series sound like vacuum cleaners. Nothing like the K20/K24s of old.

[@jesseperrella]

Hell yeah!!!! Healthy numbers man, it is so awesome to see you finally pull this off.. well deserved.

[@hussali8838]

also a full breakdown of what you need to compete this swap on the 10thgen si would be much appreciated!

[@Jxshss]

You’re the man bro. I wish i knew how to tear down a engine and fully swap something like this. Seems like alot. But you definitely give some inspiration

[@itscaptn9502]

So happy to see this especially from a development standpoint. I want this for my car someday but from a reliability standpoint over a power standpoint. As u said I wanna be able to beat on this car without worrying

[@yardbird253]

Man, nice build! A k20c4 si! 👍🏽👍🏽👍🏽

[@thuseemahalingam9780]

+1 for Drob, he tuned my Si as well. L15 with 27won W2 Turbo and vp racing speed sauce. Car runs great! Awesome guy to work with. I already had plans to kswap if I blow the L15. I've been following your build for some time on and off, so definitely something I'll be looking into for the future of my car. Well done to everyone involved.

[@darkhalo7854lol]

i really doubt your engine is gonna blow, at most probly bend a rod. thats their weak point. someone built a L15 hatchback to 420hp on stock block. he bent 2 rods when he was at 360hp from driving the car really hard.

[@darkproduce15]

hey, just fyi...Andy Cline has a set of cams from skunk 2. it's for the k20c4. it's a pre-production set and he's yet to pop them in the motor and use them! So...we're all just waiting...

[@zoriox8667]

What a marvelous build! I plan on trading in my 10th gen civic sport sedan for an SI in a couple years and this series has inspired me to get into modding! Might even do the same swap in the future, keep up the good work!

[@gavindanitz]

The Si is a great upgrade! I made a video recently on whether the si is worth modding which you may want to watch.

[@zoriox8667]

@@gavindanitz already a step ahead lol, watched it yesterday. Love the channel and really appreciate the brutal honesty while keeping stuff lighthearted!

[@Dimelowcrew]

Nice build bro! 384whp is plenty for a light car. I agree Drob is the best tuner for this platform, I will be tuning my car this coming week with him hopefully everything goes as planned.

Where were you getting the e85. I don’t know too many local stations that have it. The steering wheel is nice too.

[@nickmannino8466]

A lot of racing soon👀👀👀

[@EsenbekAliev_]

I like the idea, from outside it looks like another riced out shitty civic with a big wing, but inside it has almost 400whp and lots of torque... great build!

[@HA-xt2lu]

You got a short shifter or nah

[@Hadesccc]

Hey what’s up bro , where can I get the swap done at?

[@miketeo4627]

I know its maybe a little late now since you finished your build, but, the ecu for the 11th gen Si can control VTEC. So, could someone in theory, use the 11th gen si ECU to actuate VTEC on K20?

[@eladdurango4545]

i want to try this swap

No tachometer ?

[@4CDMA]

Try to retune with MT Tuned (Manolito). I think you hit 400 like mine accord on CTR turbo

[@gavindanitz]

People get too caught up with the numbers. Different dynos will read different hp. Some tuners will tend to fudge numbers when customers come in the with expectation of reaching a certain goal. Every car also has slightly different variances. There’s a million factors as to why one car might read 15 hp more or less, even with the same mods. I know Derek creates tunes which make good power at sustainable limit for the car.

@@gavindanitz also you can look at you MAF numbers and multiply it on 1.25. It was be +- a engine horse power.

I have not

[@adamb1057]

Just tuned my Si with a Phearable tune and for 2020 civics they specifically mention not to turn off Rev hang because it causes intermittent throttle issues. Not sure if this is applicable here or not

[@ColeStrahle33]

only took 5 hours to upload 🙏

[@darkhalo7854lol]

L15 only blow up around 500 hp on stock block from what's been seen. 350+ hp you'll start bend rods if your running too hot. i have a 290hp L15 CVT and I've been doing completely fine, i just do my maintenance like normal. ppl say cvt is shit for power but i disagree. sure is bad for 350+ but why would you even want to go any further than that on a L15. your better off getting a type r. like i said going past 350hp youll start braking stuff.

[@darkhalo7854lol]

ty for coming to my ted talk lol

[@brokentradgedy]

That wings gotta go

[@555sexydrive]

Good stuff, my deceased Si had a built block that was going to go in, but eventually the plan was to go with a K20C. Though the built block and Pfitzner gear set never went in as some lady decided I didn’t exist and hit me from behind doing at least 50 with zero braking on her part. A K20C did happen though, this was ‘21, I don’t typically buy used because most people suck, but found a low mileage ‘20 Accord Sport 25 miles from me. Called the dude, said want to see it, was about to buy a ‘22 RDX ASpec, what I was planning to buy in October of ‘19 when moving back to the US after being away for a bit over 26 years. This is dragging on, haha, but I bought the Si, because the FK8 looked pretty bad to me and I wasn’t excited about having an auto travesty, the Si coupe reminded me somewhat of my very first new car a DC5R Teggy (looks only). Anyways, got the Accord, probably should have bought it initially, but didn’t even know they existed, the 10th gen wasn’t even sold in Japan, later one was but in hybrid form only. Hope all the troubles you went through to get to this point are a very distant memory and the newfound power brings nothing but smiles for you. Just came across you, think because you either showed up as a suggestion on IG or someone I follow there highlighted you.
