f22a1 n/a build opt.

[4DRCB7ftw]

im planning on going all motor as of rite now might switch back to turbo but idk a n/a sohc has always had some appeal to me, because if it works it hummiliates ppl lol jp its just funny ... anyways the build as of right now
bisimoto lvl 2.3 camshaft ?? opinions on this cam?
would that pair up with just n/a i kinda figured with the major exhaust lift compared to the lvl 2 id get better top end

pro series bisi moto valve springs with stock retainers? possibly idk i think it wouldnt hurt the extra 200for titanium doesnt sound 2 great

2.5 inch exhaust all the way back straight pipes to 3" muffler i beleive.
short ram intake may go to cold air

tuned with hondata once its all together.. i know theres plenty of options i was wondering if this all would match up and flow nicely... i may save up a lil more and maybe get an a6 intake manifold wanted to know if that flows better and if i need anything special for that to work and save even more for a port and polish but that adds up quickly...

if i do get a cam and retainers with that exhaust and intake would i maximize the effects of a port and polish?

I have done a lot of research on non-VTEC Honda Naturally Aspirated builds. They are just cool to me. Now I am no expert, nor do I claim to know everything about them. However, from my research just throwing a cam in there, even with an adjustable cam gear(which you have to have) and a tune, won't give you the results you want. You need a higher compression ratio, which means new pistons. A new cam also means you will be revving higher than before, so the stock bearings should be replaced (idk about the F22A1, but it is true with the B18A1 ) With the new pistons and higher compression ratio new rods would be a good idea.

IMHO there are better ways to get more out of an NA F22A1 then starting with a cam upgrade. There is a thread I read about getting a lot of power for around $500. I can't recall everything from it, but some of the parts included were the F22A4 header, H23 Intake Manifold and Throttle Body. F22A6 Black box. F22A6 Camshaft and F22A6 ECU. Then you could get a quality exhaust and a quality intake so it could breathe better. After you do that you could go to upgrading your fuel delivery and electronic/ignition systems.

I am very interested to hear what other people have to say about this as I am planning out my NA SOHC build myself.

Like I said, I'm no expert, just my .02

This is true but it will only help if he has the a1 or a4 motor.

OP: As far as Bisimoto parts go you can email or call them and let them know what you plan on using your car for and what kind of build/hp range you're shooting for an they'll be able to help you out alot more as far as the right combination. Him and his staff have always gotten back to me quick and were great with eveything.

The a6 intake manifold has a daul port design. The a1/a4 intake manifold only has 4 ports where the plenum and runners meet. The a6 has 8. 4 of them are closed at lower rpm for better low end response and once you get into the higher rpm range the other 4 are opened by vacuum to let in more ir so yeah it'll flow better. Getting the head ported and polished is also a good idea. The f22 head is one of Honda's best flowing heads so opening it up even more will give a noticeable difference. You may want to look into getting everything port matched also.

dang okay im trying to spen around a grand for now anyways would it be best for me to just get the head P&Pd and then go get her tuned with the bolt ons?? id probly have like 100 maybe left over cuz i know a shop that will p&p for around for to 500 as to the depth of it idk gotta talk to em i know they did my freinds just a minor brush up and clean for 120.... and about the a6 intake mani i have an f22a1 so how would i go about putting that on do i need a different ecu like with the h22 intake mani? seems like a hassle for just a manifold maybe worth it idk...

i was planning on just opening up my manifold with a dremmel lol

[KB7]

A new cam also means you will be revving higher than before

I know you said you are no expert, i am just trying to clear one little thing i saw up, but just changing the cam wil not allow a motor to rev higher. the amount you can rev is dependent on piston speed, which is calculated by the stroke. The f22 has a very long stroke compared to the dohc vtec motors. which translates into very decent torque numbers.

Going after your IM with a dremel can actually hurt it's performance. There is a reason people take their stuff to reputable shops for that kind of stuff. It takes a lot of experience and know-how to get stuff like that right. I would get the H23 IM and take it to a shop to get port matched with your head. Though I would get just bolt ons and other minor stuff before a p+p.

What I was referencing to was that a higher cam profile would benefit from a higher shift point. The larger cams work better at higher RPMs, therefore a tune to allow for revving higher is needed. I am well aware that a cam, in and of itself, will not allow you to rev higher

[Joey GT-R]

Why do you want a 2.3? That cam is designed for nitrous, and I didn't read anything about spray....

If you're only trying to spend about 1000 right now. Your best bet is just a Bisimoto header with a chipped ECU and tune. It would probably net you the best perfomance gain right now.

[mr_naler]

Some people have talked about doing this, I'm not sure if anyone has. I haven't looked that much into it. It has a significantly larger intake profile(.401 compared to .34 or something like that). I don't know if this would be beneficial for an NA application, but some seem to think it could be.

[Brandoncb7]

about the a6 intake mani i have an f22a1 so how would i go about putting that on do i need a different ecu like with the h22 intake mani? seems like a hassle for just a manifold maybe worth it idk...

The iabs are controlled by vacuum. As far as an ecu if throw the p12 in your car it's supposed to give around 10hp. Just another simple thing for more hp.

[4DRCB7ftw]

how much will a bisimoto header get me? is it even worth it? i know i want to get a tune for it for sure so that would probably put me at 1200 with a tune. would this be more reliable than a turbo set up?

[Brandoncb7]

Bolt ons and a tune if done right will be more reliable than pretty much any turbo setup. As far as the Bisi header is concerned.......it's worth every penny.

[4DRCB7ftw]

dam lol makes me wanna go for it..... but dang i just wanna get around 200 to the wheels give or take 10 or so man with a tune thats my goal.

[wed3k]

start saving

[jhondayaaj]

Agree with above. I spent 5k on my old sohc setup and got 165 whp with bisimoto setup. You have to think about an adj. fuel press regulator, and a higher pumping fuel pump fir the tuners sake. And a adj cam gear as stated before. 200hp is hard to get to on our engines if you don't have the funds to get there. I only had bisimoto header and his level 2 camshaft and cam gear and bolt one and fuel management and a tune and only got what I stated. No p&p no higher compression piston either. Good luck though.

[4DRCB7ftw]

lol screw it
