I’m new to the forum so take it easy on me. I have done hours of searching and have not found what I’m looking for. I have a k20a2. I know I can easily make more torque by using a k24 bottom end unfortunately rules don’t allow it. I know bolting on I/H/E to help but with the rules I am very limited. I have not found a build that falls within the rules I’m allowed to run. I will post the rules below and hopefully with the vast knowledge on this forum you can point me in the right direction. I don’t have a HP goal I’m trying to reach. I just need usable power and torque on corner exit. Thanks in advance for the help.

Yes it is! Hopefully something can be done that’s close to being legal atleast 🤣

Thanks so much for the feedback…. What about the block? Pistons, rods combinations? Higher compression? Can’t wait to get this thing built to see what kind of numbers it makes after being tuned

@Them Witches I have a narrow build window and knew it would be best to ask all of you what would be best. I wanted to keep the bottom end stock if possible. As far as the head I was thinking a 5 degree valve job to help with corner exit. Lightweight springs and retainers. Stage 2 cams.(Deciding on the right cam is what started all this).s see one type of header. Kpro and a good tune. That’s basically all I had in mind when starting this. I wasn’t sure what brands. Honestly the more I researched the more confused I would get. One thread would say a certain cam is the best. The next thread it would be garbage. Just so much out there. I hope to start a thread and get direct info for my build. So far the feedback has been great! Thank you all

I am running the DC5 chassis. I have attached an example of what the chassis will look like. The only thing that has to be stock is the floor pan and fire wall. The suspension just has to mount in one factory location. The entire body will not be used and replaced with a stock car body. This is a car a friend of mine built for the same class I’m running in

This is the type of track we run on. This track is 4/10 of a mile with 17 degrees of banking in the turns and 7 degrees on the straights

@Them Witches thanks for all your help. I feel confident I can make the car turn and get the gearing right. I have never built a Honda engine and wanted to make sure I got the most potential out of the engine. Your advice has been priceless.

That would be a good goal for me to reach. Like I was talking with @Them Witches if I can make that much HP/Torque with the proper gearing the car should be what I’m looking for.

My goal is to be done by the first of next year. Budget is not a factor in this. The racing season is winding down this year. The car is a Bare chassis at this point. While the engine is getting worked on I will continue to build my roll cage and install the suspension. Everything will be brand new. I don’t want to be in a rush. I want it to be right. I have been successful in the past with other cars. Last thing I want to do is throw this one together and not live up to the standard I have set for myself. And as far as gearing goes each track I go to will be different banking, straightaway lengthy, turn radius and length. My home track will be 4/10 of a mile. Some others may be 3/8 to 1/2.

I’m not 100% sure but if I ran that setup I’m sure they would figure out a way to not make it legal 😂

I’m not opposed to doing some work in the head. The issue would be it just can’t be obvious if it were ever taken off

Just had a conversation with the tech man. He said that setup would be illegal because it would be forcing an “additive” into the engine and would in his mind cross the line of being N/A. Was told that the rules for next season will allow cold air intakes. So that’s a plus atleast. Looks like it’s time to “cheat” up that head 🤣

I will check into it. When I copy and pasted the rules I left some things out because I wasn’t expecting such in depth help. The things I have learned up to this point should definitely help the engine push the limits of legal abs slightly past. I can wait to get this build started

Just had another conversation with the tech guy. CAI will be legal. Just can’t drop below the crank. No funneling of air of any kind to intake. The factory air box would have to remain stock with no modifications if it were used
