+Evans Tuning What's your opinion on the 4.77 FD on a ap1

[@blasphemicwhale]

LHT swears by the Skunk2 header on a supercharged setup, and an OEM intake with K&N filter on NA, and they have almost 50 supercharged s2000 builds completed at their shop, with tuning

[@DJToneRI]

So much experience and valuable information here. Clear and concise just the way it should be

[@sungod1976]

I thought honda changed the banjo bolts in mid-2002 vs 2003. Great content and public service with this video. Thank you!!

[@coolguy91975]

+sungod1976 Yes, this was the only issue I found. Otherwise it's excellent.

[@superstreetking95]

I thought it was for 00s-early 2002???

[@TheChannel1978]

Also think Banjo bolts got upgraded from MY2002 onwards. My engine was lost due to a dropped value. When the replacement engine was sourced we swapped valve retainers for ap2 versions and checked banjo bolts. They were already the newer better type with more spray holes, and the replacedment engine was a 2002. This man has good advice, I learnt it the hard way

[@joedoole3527]

One thing I think you forgot to mention that could be important to road course guys, or any racing enthusiast really, is that while you may only see minimal gains across the board with an aftermarket header/exhaust system power wise you will also see a significant reduction in weight compared to stock components and that is certainly no waste. Yes the quality parts, especially for the S2K are pricey, (gotta pay to play!) there are some gains to be had. We typically see the J's racing design and its quality replicas produce a solid 5-6whp gain across the board from ~4500-redline. We also have seen gains of 10-12whp with the Hytech header + exhaust system when used together compared to stock as well as a significant difference in weight. While the overall power gains may not be as impressive as with other engine platforms, weight savings is always a good thing as decreasing weight is the single most effective way to increase performance in every aspect. Braking, handling, acceleration, fuel mileage, etc. are all increased when weight is decreased, so that can be a factor for some in their choice of aftermarket parts as well. The F series engine is indeed very well engineered from the factory though, and we have made over 250whp on stock short blocks, stock cams, and bolt-ons. Aftermarket valve springs are a good option as well because the stock cam/intake manifold/head can all flow higher than stock redline, so with tuning and some light head work 260-270whp is easily attainable with stock cam profile, stock compression, stock bore/stroke etc. At this point, the stock header still flows enough air overall to not be a restriction, however the runner and collector design can stand to be modified to speed up that flows velocity and promote better scavenging therefore increasing power potential somewhat.

[@philspaghet]

Yeah, best bang for buck is just to keep the stock air box and cut out the divider and remove the snorkel, way more volume and you're still shielded from the engine bay

[@seanm.collins9888]

@@philspaghet best bang for buck is to leave it stock and take a track instruction course.

[@philspaghet]

Not sure if it's mentioned but if you boost make sure you upgrade that diff. It tends to snap with power like that.

this guy knows his shit! just look at his hands lol

[@hovsepmaksoudian8824]

Hes ok.. but hes missing things for a total ballance .. with the s2000 its hard to make power.. but you need to loose weight.. thats the Key with the s2000.. remember this for NA setup!

[@rightfight100]

Should I go K20 coils on my stock AP1 for now before I go supercharge?

[@aurielcastro9903]

Yes 04-05 coils are a great upgrade.

[@mrmidnight32]

Idk if I can take any of this seriously when his first recommendation is intake.. Especially after all of the testing and research ive seen done to show the stock airbox is not a limiting factor...

[@ayowser01]

NoOneImportant556 I think a snorkel into the oem intake is the best option outside of a Mugen, ASM or the like.

[@TheChannel1978]

Yeah, that sounded really off. You don't get 10-20hp from an intake and a test pipe with a tune. I can say from personal experience the information on banjo bolts and valve retainers is accurate and important if you own an AP1

[@calartian85]

LHT recommends altering the factory air box. Delete the splitter at the intake, delete the baffle wall inside the box and the from the left over baffle wall material cut out a piece and glue up a cover for the little door under the filter tube. Works great.

[@tannerlierman1489]

Great video

[@gravityhammer25]

Very informative thanks! S2000 is a great platform!

[@android-ud2nf]

what intake, test pipe, and exaust would you reccomend for not only power but for a really good mechanical sound. not just rasp

[@vtbbs2k]

I believe that banjo bolt problem was fixed mid 2002 around engine number 1025300. Also change retainers they crack pretty easy changed at 97k found hairline cracks on 3

[@vtbbs2k]

@alexandre dubois if you’re not going to force induction it’s not that big of a worry but I’m getting ready to turbo and changed them and saw small cracks on three of them. Not really a way to tell if they are bad they can be seen using a dental mirror to inspect. But there really isn’t a way to know or feel. Cracks were so small on mine I couldn’t tell until I removed them.

Thank you very much for the info!

great info! great vid

[@ryanh5712]

I put on a J's rep Seibon hood before seeing this video, but after seeing this video I removed my intake box cover, got a test pipe and the vtec transition is something to waste gas on. I also feel a smile factor going on and idk if it's cause of the transmission or the HP gains.. My next curious thing to mess around with will be to buy a Ballade sports 70mm throttle body and have my 05 plenum bored out to 70mm. Will that be worth the $180??? thanks evans tune for cheap solutions, for gains!

I have a s2000 but I don’t wanna go forced induction what should I do to get power

[@F22C1]

Hey Jeff, would a turbo s2000 benefit from aftermarket cams like the BC turbo cams? What about an intake manifold designed for turbo set-ups? You've answered a lot of questions I had in this video, and I thank you for that. :)

[@EvansTuning]

+Le Enderman Glad you found the video to be informative. For under 800-900whp, the stock S2000 cams are more than sufficient. The intake manifold is sufficient up to the same power level. Honda did a really great job on the cam profile that works well on a forced induction set up on an S2000.

thank evans , I posted this on our kraftwerks s2000 facebook group.. it answers alot of our common questions. you have tuned a couple car there. we have alot of questions about e85 for our specific set up. like what pump and injectors to go with. we don't have a definite answer. I my self run e85 on the grams 1000cc and grams pump.. but injectors are being maxed out..

[@EvansTuning]

+johnzal79 Thanks for sharing the video! We're happy to hear it's been a great source of information for many people. We have already filmed a video regarding fuel systems which will be out shortly. In the meantime, to answer your question, we'd recommend using ID 1300cc injectors, Walbro 400 LPH E85 specific fuel pump, and the SOS fuel pump re-wire kit. This combination of fuel system components will support about 550-600whp safely on E85.

[@NateDaGreat808]

Does the K20 coils and have different dwell timing than the s2000? Or is it a true drop in. Wondering cuz I'm using a platinum pro plug in. Wondering if I been to change the settings. Thanks. Nathan

[@ShayneJdm]

What about fuel injectors?

[@Khanman1]

Do the airbox mod instead of new intake

[@isabellab617]

Is it possible to get around 400hp N/A? If so, how? I know it might be expensive, but ftw, I need to know

[@AlyxTF]

It would be near impossible and if it was, it would cost a fuck ton. Better just to get a high end supercharger and get the same results

[@AlyxTF]

+DerpyOrange there's a ton of ways to do it NA, but nothing will end up being as cost effective as a turbo or supercharger

[@isabellab617]

+BlameThe WhiteGuy +DerpyOrange I was thinking: intake (ITB's +13hp), exhaust(+15hp), ported head(not sure if it's called this way in english; +10hp), racing camshaft(+/-35hp), comp. ratio 16:1 (yes, there are guys running ratios as high as this on S2000's; +30hp), lightweight valves and springs(+10hp), etc. There's already a 113hp gain, which means the F20C now has 353hp. 🤔 Correct me if I'm wrong with the gains of each mod.

[@AlyxTF]

+Eduardo B. Lpz those are all "hypothetical" gains. You will literally never see 15hp from an exhaust and most likely you'll get like 40-50 hp from all that

[@danielyoyoechavez8847]

[@Ap1s2k]

Hey Evans tuning; I want to go e85 and I have an inlinepro block and the cylinderhead already done , i just don't know what injectors / fuel pump to get. My end goal is to go turbo with a gtx3076r and get as much hp as possible out of that on different tunes. I have an AEM infinity ECU and would just like to know what to get.. Also my car is apart and i have a brand new ACT Clutch with OEM Disk & OEM flywheel throwout bearing and pilot bearing.. won't be enough idk what to upgrade the disk to as im not done with the whole build yet and don't have a turbo yet but do want to drive the car this summer N/A Just don't wanna take things apart again after to swap a clutch because it slips due to added power...

What fuel pump and injectors should i be looking for when im aiming for 600-650 whp ap1 turbo?

[@lovinmuzik1108]

Nice info video. All is needed is picture for dummies like me 😂😂

[@fastb4ck620]

What would you tune with for a 00-05 with just test pipe and intake?

[@EvansTuning]

+Fastb4ck Either an AEM EMS or a Haltech Pro Plug in for a PNP, cost effective option. Hondata Kpro is also a great option; however, it does require changing hard parts on the engine. This will add to installation costs, but the benefit of Kpro is that you are retaining OEM reliability with the factory computer.

[@agusjoao2711]

Hi mate, one question, what about engine interiors like oil pump, crank, conrods or pistons? What are the best options or manufacturers for them if I'm planning to install a turbo? Many thanks!!

[@speedblazer94]

Can you install a wideband on a stock ecu? Is it even worth it?

[@davidcrandon2329]

Yes. No.

[@Vikseemungal]

Do you offer an etune service?

[@EvansTuning]

+Vik Seemungal We discontinued our eTuning service about a year and a half ago. We are; however, open to and currently booking times to travel to tune within the US and Canada.

[@jamesandrew58]

Do you prefer the Haltech Platinum Pro or AEM Infinity on a AP1?

[@EvansTuning]

+James Andrew Cardenas Each system has their own place on the AP1. AEM Infinity is better suited for a high power turbo build (600whp+). At these power levels, traction control and knock control are pretty important and Haltech does not offer traction control. In addition, Haltech's knock control is not as fast or refined as the Infinity. Having said that, Haltech is more than fine for about 90% of the set ups that come through our shop and is a rock solid system.

[@jessechen998]

what about supercharged with water/meth injection with Australian 95 octane?

[@aaguirre123]

I looked at the part numbers for banjo bolts and oil jets and they are the same for the AP1 and ap2. Should I still replace them? I have a AP1. Thanks for the information.

[@davidcrandon2329]

Yes. Same part number because Honda makes only the upgraded ones now. You have to check your VIN # to see if you have old or newer AP1. Banjo bolts were upgraded in mid 2003 model cycle.

[@kevinzamora1868]

I wanna mod my 03 s2k and I wanna push as much hp as I can without getting a turbo or supercharger yet. I’ve already got a cold air intake, a short shifter, ACT racing clutch but I wanna mod to push more hp what do you guys recommend?

[@vkoptchev]

Any idea if the European AP2 spring retainers and banjo bolts have been changed? it's still F20C.

[@tomtom255]

I think any 03-and newer has the newer banjo bolts and retainers, at least here in the states. I assume Honda would have made these standard even though it's still the F20 and not the F22...

[@TheFunat9000rpm]

What do you guys recommend for engine management for a supercharger application on an Ap1?

[@EvansTuning]

+Florian Firlus Either an AEM EMS or a Haltech Pro Plug in for a PNP, cost effective option. Hondata Kpro is also a great option; however, it does require changing hard parts on the engine. This will add to installation costs, but the benefit of Kpro is that you are retaining OEM reliability with the factory computer.

[@ninofajardo1288]

What size test pipe 60 or 70mm?

[@AlyxTF]

Always the biggest size possible lol. If you have an aftermarket exhaust make sure it matches or exceeds the size of the exhaust as you don't want it to bottle neck

[@Tommikegetitright101i]

I want to get a test pipe and a intake but I don't what to spend a 1000$ on a tune from AEM :( help me

[@EvansTuning]

There would be no point to modify the car if you don't plan to have it tuned. You won't be able to take advantage of the power you can make doing those modifications. AEM and Haltech would be your 'cheapest' option for tuning (assuming it's not an 06+, in which case the Hondata FlashPro would be the way to go); however, you should always keep in mind that the cost of engine management and a tune is far less than the cost of an engine rebuild.

[@F22C1]

Considering supercharging my car in the future. Would it make sense to run the smallest possible pulley, even if I might switch between 93 and 100 octane periodically? Ex: Don't want to use 100 octane on long trips, yet don't want to swap pulleys every time I wish to do so. Can you pull enough timing, while still using the small pulley, and safely run 93 octane? Or is pulley swapping an inevitable fate with superchargers?

[@Balo657]

Hey Evan, I got a 2002 S2000, I want to upgrade my car but stock ECU can't do any tuning, so is the AEM V2 the only option I have?

[@EvansTuning]

AEM, Haltech, and K-Pro are all options. Check out the link in the video description for more details.

[@Balo657]

Thanks! Opinion putting nitrous on a s2000?

[@EvansTuning]

+Balo657 We don't recommend nitrous. Typically, people will use it as a 'cheap' means for extra power. When you factor in the cost of the kit plus having to regularly fill the bottle (let's say 15+ refills) you'll start getting close to the cost of a supercharger kit. This would be a far more reliable option and would net you more power.

[@splice247]

aem v2, the new aem infinity, hondat kpro, i would say go with an aem standalone, as a krpo is just a chipped stock ecu but cost the same

[@soto575]

if you make it 2.2 is it worh it ?? i hear some people doing that in a ap1 and still rev it at 9 rpm and making some good gains around 10 hp i dont remember exactly .

[@joedoole3527]

Personally I don't think the F22 swap into an AP1 is worthwhile. If you are looking to replace a tired or dead F20 then this is maybe something to consider, but to swap a healthy F20 for a F22 is a waste of money. The power difference between the two is minimal in stock form, and you would make much better use of your money just fortifying the F20C with aftermarket internals rather than an OEM F22 2.2 swap.

[@soto575]

Joe Doole i am not taking about swaps many guys they putting stroker kit upgrades to the F20C engine to make it 2200cc displacement. and some of those guys they saying that you can rev the ap1 with the 2.2 liter up to 9 rpm.. which in the ap2 you can not rev it more that 8. and by doing that they make a good amount of power. but i dont know how reliably is it

[@G23teknik]

Great video. Please do one on k series prefferably on the k20a2.

[@TheARJ15]

Whats the best way to ecu tune an ap1? I know the Ap2's are Hondata compatible but what is the best option for earlier s2k's?

[@superstreetking95]

Ap1 ecu's are unfornately not flashable unless you have a chip installed in it, best thing to do is stand-alone ECU like AEM, ECUmasters, or Haltech.

[@DJLOUIE1000]

What ECU upgrade to you suggest for a 02 S2000? Bolt ons for now but SC in the future. I've heard of AEM Series 2, Infinity and Kpro.

[@joedoole3527]

AEM is hands down the best option for a modified S2K in my opinion. I'm sure Jeff will chime in eventually, but K pro isn't really a great option for these cars because by the time you purchased the Kpro, an early RSX ecu, the required sensors, valve cover etc you are already in the realm of what AEM would cost anyway, but without as many features. There are quite a few good Hondata tuners out there, but less of them can reliably tune the S2000 on the Kpro, as it isn't as straight forward of a conversion as many would like/hope. Haltech has some good options as well, but from a reliability, user friendliness, and overall performance standpoint, AEM ems gets the nod for the S2000 every time in our shop.

[@indecisivegearhead]

Jeff, when upgrading to a walbro 450 pump would you recommend going to an aftermarket rail/regulator or is the stock stuff sufficient?

[@superstreetking95]

stock rail may work, but I would upgrade to a aftermarket one from Radium with larger injectors depending on the application you are using it for such as turbos, supercharging, or larger stroke.

[@KPad87]

Will test test pipe throw CEL?

[@KaDaJxClonE]

It shouldnt, if it does, move the O2 further down the exhaust. but the only O2 im aware of is right after the collector on the exhaust.

[@DJLOUIE1000]

What ECU tuning do you recommend for a 2002 with SC? I want to keep full functionally of my cluster. Thanks.

I would definitely upgrade to supertechs, Brain Crowler, ferrea racing, or Skunk 2 valves. F20c valves are not very strong especially for early model S2000s have been known to crack.

In some countries it is

[@alimehrozi2828]

false the best bang for buck mod is 4.77 gears

[@joedoole3527]

Maybe for pulling a couple tenths off a 1/4 mile time, but everything else (fuel economy, top end speed etc.) will suffer. Also, gears on an otherwise stock S2K rear isn't really smart, because there are much more important areas to focus on with this fairly weak drivetrain. We have broken stock parts with stock gears at 260ish whp launching hard on sticky tires, what do you think 4.77s would improve upon this?

[@alimehrozi2828]

Joe Doole anyone whos buying 4.77 gears is most likely going to a track with turns or autocross.. you know... what an s2k is actually for... if people wanna build a drag car starting with an s2000 is a mistake from the beginning..

[@superstreetking95]

however depending on either you have a AP1 or AP2, 4.77 gears is the best bang for a AP1. but if you do a AP2 transmission conversion I would use 4.44 gears with reinforced CT housing to make it gernade proof. especially if you plan on supercharging or turboing.

[@cutdepiefails6596]

It's simple. Fuck test pipes. 3 inch exhaust (ressonators and mufflers at will), a good CAI with a large diameter 2.5 to 3.5, aem infinity and voilá 240 whp to 250 whp. Get headers, intake manifold and some mild cams and 280-300whp will appear, reliable and strong.
