Ferrea 6000 valves
Do you need the valves really? They are size-wise just the same, aren't they?

3 angle valve job
Done by 4Piston?

Are those the re-visioned or the first version ones? This are pretty big cams for almost 500 ccm/cylinder and your defined engine speed limit at around 8600 rpm. But they are your choice for the next level step of your project. Did they included any kind of hardware VTC limiter? Don't relay on software VTC limiter, especially not if you use the stock Honda ECU.

3 angle valve job is being done by 4Piston. Everything is being done by them.

The cams are the re-visioned ones, not the 1st generation. I have not paid for the cams yet. What cams do you suggest? I am all ears, I have not made any mistakes ordering anything. I have time to reconsider, I can send 4piston any valve springs combo.

I do not need 80% of this build Markus. I wanted it all like a thirsty fool to a fresh water spring

Ok, I am interested in measuring it flow-wise before and after. Just ship it to me :D.

Depends on your plans. If you keep the stock near small block concept and miss the stock cam (you are going to sell it I saw), then I would recommend a DC DIC or TODA A2. Preferable the later, which has a much nicer torque curve potential, but it is maybe easier to get the first for you. In case of a future revival of the small block to get it capable for 9500 rpm the RR3 might be one of the candidates like DC 3.2, but my favourite is still the TODA A3. This is a 15 year old design, but it is the best compromise regarding valve timing if power should hit at around 8500 rpm within a 2 Liter NA-4 cylinder regarding durability and performance. The valve springs of TODA have a lower spring force then the OEM, as they use a different kind of resonance safety concept. This is one of the most efficient valvetrain drivers I ever head on my analyse tools. The RR3 are much bigger and harder to the valve train, this are race application high maintenance cams only and are fine with peak power speeds around 9200 rpm. The differences in costs to adapt their potential is around 4k USD within the power aggregate.

Hunting and collecting, those are really prominent and though challengers :D

I have owned a fast Honda for over two decades, collecting. I also was a cocky youth that happened to be a pool shark and would place bets that if I won I would get to drive the losers car. I always picked the best cars I could never afford hahaha. That is hunting.

Nothing to add, just broke and do not have money to proceed further until after the 1st of the year. I should call this build the never ending story going no where at the moment lol...

I am used to things not going my way, so there is nothing here to faze me. I know this build will get done and it will be worth it once it is done. The biggest hurdle at the moment is raising the money for cams and getting the engine back in the car so I can begin the install install stages of everything.

Thanks to all the members hanging out on my little build thread, your positive words and support have been more than helpful and I feel blessed for it. Have a wonderful holiday to you all.

@LotusElise
If the S2000 AP1 PCX valve springs are good til 9,000 rpm stock with AP1 cams, would you think the valve springs would be able to handle Toda A3 cams if the desired rpm for the build is 9,000 rpm? I am not looking to go over 9,000 rpm anyways.

I am asking b/c the valve spring order I made for (AP1 PCX) was canceled. However, I have already invested in the dual valvespring set up by means of already purchasing NEW : PRB dual spring seats, Supertech Ti retainers, and PRB steel retainers if the Supertech Ti retainers are not recommended by 4Piston when they do their testing. This is why I ordered NEW PCX yellow outer valvesprings (In. & Ex. sides) w/ the use of the PRB inner valvesprings that I already have. Now that the PCX valvespring order was cancelled I have options. However, if I cannot use the following NEW : PRB dual spring seats, Supertech Ti retainers, and PRB steel retainers - I will have to sell them most likely taking a loss on them. I mean I am only talking $350 already invested.

Do you have pressure and lift data of them available? Lift height and spring force rate as well as the resonance frequency has to fit at least.

Happy Christmas Gabriel! A wise guy once said, believe in your dreams is the first step of realizing them. You are in the same boat, I've started my engine built in 2015, which was 6 years ago. There is still a way to go, while I see the finish line. I believe many of us who started a project see added challenges like family, work, and other stuff which all also need attention, support and passion. You are on a good way Gabriel 🆙. You have great passion for your family, engine and car project and your moderator job at K20a.org, which I appreciate very much, you do. A perfect motivator to get it finished and to drive it later on. This project will get finished, I have no doubt on that.

No I do not have information on the those springs. My order was canceled on them b/c they had not received them in over 3 weeks and looked like it was going to take another few weeks. So I am at a point where I either use my 2002 PRB oem dual springs with DIC's or go with an entirely different cam spring combo.

Happy Christmas to you Markus. Thank you for the honest words from the heart brother, the words are more than helpful to keep the faith it will get done when time decides it to be for each one of us. You are right projects take time, it is not always how fast we get there it is the lessons and experiences that make it count. I am thankful for my daughter, family, friends, and for you asking me to be a moderator here. The vibes are good here and the forum has always been a favorite of mine, thank you Markus. I hope you have a great holiday with your family.

Merry Christmas Mr Witches and Lotus guy and good luck with your builds, I look forward to seeing them here and on YouTube kicking butt.
Merry Christmas @2Cent, I hope we can do some videos soon. The 1200 hp drag engine will be built next. Plans are End of May working on the DAMPFHAMMER.

Great to read this from you.

Thanks, we will do our best to utilize my 2 weeks holiday: get rid of unnecessary things in our shelfs, have a good time with my two Ladies, reading some literature and designing the intake manifold for the 1200 hp drag engine. Aaaand my wife bought a business (Ergotherapy Praxis with 7 employees), where I invested half of the budget, she likes me to be the go-to guy there. She has already a long list of tasks for me, I will definitely not get bored :D.

The Eibach dual springs have a nice resonance setup, the are good for 9200 rpm and they are locally available at your place, as well as they have a low seat pressure, being more efficient on the friction stuff. Those can cover 13.5 mm lift cams, which would cover TODA A3 cams or DC 2.2 (OG series).

Gasp! I did not realize you were shooting so high!
