K-Series Motors are very popular here at TDC. We have tuned a lot of them, Worked on a lot of them, we even have one of our own (Hubert's 600+whp RSX-S). But this one was a different kind of build that we are all very excited to see finished. Nhia brought us his RSX-S with high hopes of making more power out of his K20 N/A build. K-motors can be very responsive when having the best parts, and Nhia wanted to do it right.




We installed all the parts listed below:
1.) RDX 410cc fuel injectors with clips
2.) IPS K2 Iron Core cams
3.) Supertech dual valvespring, steel retainers, seats, and seals
4.) Skunk2 Racing 3" Muffler with 3" KTeller Piping
5.) Hybrid Racing Timing Chain Tensioner


His Modifications already on the RSX:
1.) Injen cold air intake
2.) RBC intake manifold with Karcept adapter and Hondata intake manifold gasket
3.) Kiddracing Krusher header
4.) Hondata K-PRO



These pictures was featured in out TDC auto blogger earlier in the week.



The head all set up and ready to go.



Hybrid Racing Timing Chain Tensioner Installed and ready to go.



Skunk 2 Muffler all set up and welded together. We actually had Nhia come and show us exactly where he wanted everything to line up for ultimate satisfaction.



And here is how she lays until tomorrow for the tune on K-Pro.

We will have the charts posted as soon as we complete the tuning on this RSX. So keep posted on this build!


And on the roller:

Update on numbers.



Roughly 140K miles and still decently strong.

i don't think i would ever turbo a motor that didn't come with one. that's just me being unreasonable probably, but it's how i am. so for me, it's a breath of fresh air seeing someone do an n/a build on a honda. when i had my Si ('06 K20Z3), i priced out and entire top end from Skunk2 for $2,200 that they dynoed and put down 298hp. i'd say 100 hp for $2,200 is a pretty good deal. it was definitely cheaper than a turbo kit at the time. plus, for my purposes, any more than 300whp in a fwd car is just useless. torquesteer ftl.

props to this guy for "doing it right."

^I agree. For most people and uses, N/A power is the best route. Especially with the K series engines. They respond so well to bolt-on parts, and make great power for the investment.

what all is included for $2200?
i'm going to assume no engine management (did it even exist for the 06 si back then?), no dyno tuning, no installation, etc....
i don't see 298 hp happening with stock compression...so?

their parts are so expensive. cams-$756, header-$837, valve springs-$254, Ti Retainers - $208, Pro Intake Manifold - $525, throttle body - ~$400,
we are way past $2200, even at wholesale prices, and you won't make 298 hp without some form of engine management (Flash Pro exists now - $695), probably a clutch, and probably higher compression pistons.

the car above has a lot more than $2200 in parts and he is still a good 25 hp away from 298 crank hp

i was just going off of what they did to their SiR. all of the motor upgrades cost $2,200 then. idk what they are now. and i can't remember if that included the engine management, but hondata did offer theirs (K200/300/Pro). and Skunk2 put theirs on the dyno and it made 298hp. check their site. maybe it's still up there.
