This list of mods are to change the car as an all rounder that enhance performance but also the looks and daily usability. Olly has done a lot of modifications to his EP3 Type R over the years but this list is what he thinks are the most important things that you should focus on to get the most out of the car in all aspects. This list is ordered in “importance” order. With the least important first. It starts with a refreshed or new rocker cover, this freshens up the engine bay and gives the car a more new feel just by looking at it. A Mugen Style Spoiler is next and this is the best aesthetic mod you can do to the exterior of the EP3. We then move inside the car for the double din head unit with CarPlay or Android Auto and some upgraded seats for comfort and support. It is then onto power upgrades, both the inlet manifold and 4 2 1 exhaust manifold are important additions to the car when going for the most power with an ECU Remap. More importantly, and something you should change as soon as possible, is an intake or induction kit and a cat back exhaust or even a blackbox. This makes the car far more enjoyable to drive and means you car really clearly hear the VTEC crossover. Most importantly for this car is the handling. They are already great from Honda but with good tires, springs or coil overs, a fast road set up and a Limited Slip Differential, the EP3 is elevated to another level!

[@OllyRoss]

Nice man! Sounds like a pretty sweet car!

[@barrymclaughlin6190]

Final drive definitely worth doing aswell

[@myrealnamedoesntfit]

Man. On my 250k mile EP3, I'm just wondering when I'll find the time to address all the normal wear and tear items. Hopefully this summer, but I've been saying that for the past 5 years. Best stock car I've ever owned, just keeps going.

[@OllyRoss]

That is pretty good going man! They love to carry on going! Probably worth looking into the perishable bits though. They could cause you more problems in the future if you don’t start ticking them off. Such a great car though isn’t it!? Smash its head in and it still works perfectly

[@randyluna8472]

I recently purchased a work truck, so that is my daily now,my EP3 si is now on jack stands, not to stress myself I begun the tear down in sections, like a big puzzle, a little at a time, once u begin u start picturing the light at the end of tunnel...trust me once u start you'll feel glad u finally started

[@myrealnamedoesntfit]

@@randyluna8472 yeah, can't wait. Got about every common leak going on and I know one (maybe both) of my CV boots kicked out grease a long time back. Couldn't find a tear in the boots, so I just cleaned it up. Muffler rusted off ages ago. Tried a cherry bomb last summer, but the entire exhaust was so corroded that it broke off where I attached the muffler with the u-bolt. Thankfully I hung the muffler. Definitely gonna be some work, but damn it's a fun car to drive. Got my wife a 2023 Bolt EUV a couple months back and that instant torque is cool and it's a comfy road tripped, but if it wasn't for the price of gas, I'd be taking my EP3 on road trips. So much more fun. I get so bored driving a modern car, let alone an EV. lol

[@randyluna8472]

@myrealnamedoesntfit I began buying parts about a year ago, I pace myself so I don't break the bank, I buy quality parts even though it's a little more expensive but having great reliable parts work best plus they last alot longer, I do alot of research and always try to source the best price, it's a process for sure but take ur time, have fun plus it's a good learning experience & in the end you'll be able to say I did the work myself & it will be that much better, these are fun cars for sure plus it's pretty cool cuz there's not that much left around where I live, it's a forgotten jewel, can't wait to roll it out super clean & restored to it's natural glory

[@joshsd7767]

I love an EP3 I'm a massive fan of your build. Your channel is what convinced me to buy mine in the end. When I got mine I fully intended to modify it but with how much I enjoy it stock and with how few miles it has on the clock (under 46k!) I've left it alone.

[@OllyRoss]

That is so wild man! I am glad it has lived up to how I made it come across on videos. Thanks! Jheeze, I can see why you haven't done anything with it!

[@TheMightyBHD]

Nice video dude ! as a non Honda owner looking to dip his toe into buying one with little car modding experience , this is a great informative video :)

[@OllyRoss]

Thanks man! I think you will have great fun with it as they are such a raw drivers car!

[@edbayly]

Thanks for inspiring my build mate. Awesome vids and great advice, Mine is geting mapped on Thursday! 🎉

[@OllyRoss]

Damn! That is wild! Thanks for watching! How are you enjoying the car now it's been mapped for a bit?

[@edbayly]

@@OllyRoss I got it mapped by Romain on your advice and I have not been disappointed! It is a total game changer right?! So impressed with the power in 1st and 2nd gear now specifically but more power everywhere. I've gone for haltech elite so still having some fun setting up launch control and shift lights myself and want to get oil and coolant sensors in next - the OEM temp gauge doesn't work with Haltech so have got no idea how hot she is (Romain did however set a Rev limiter to 3k if coolant overheats so should be safe). Honestly mate, this whole project was off the back of following your channel, I always wanted an EP3 but seeing you doing it - the ups and downs - really inspired me and shaped what I did to mine. Thank you!

[@chillfill88]

Just got a EK today😊 big project incoming. Has been sitting for 13 years 😅

[@OllyRoss]

Siiiick! 💪🏻💪🏻💪🏻

[@jonmcclane7433]

Greetings from Indiana, you have a beautiful Honda. I’ve tuned my 8th Gen Civic Si, and added a Catback Exhaust and AEM Cold Air Intake and you’re right it transforms the Car.

[@OllyRoss]

Thank you! Yeah, it really does make it so much more fun and engaging to drive!

[@j_jc18pl24]

Working on beefing mine up now suspension wise, I’ll definitely be getting a spicy alignment 🫡

[@OllyRoss]

Nice one! I have a video on all the bits that make these handle so great if you want all the sauce? kzbin.info/www/bejne/hpXSnqiPgriciKMsi=gVW_ipARb4uljdlH

[@east83music]

sick ep3! 👌🏽

[@OllyRoss]

Thanks! Appreciate it! 🙌🏻🙌🏻🙌🏻

[@iainstewart6200]

I would suggest some form of brake upgrades also

[@OllyRoss]

You could do a more aggressive pad but it depends on how you drive it too. It was too much of a variable for me to add it onto my list but it is a valid one for sure!

[@manxracer5541]

Tegiwa strut brace would finish engine bay off nice clears the tegiwa induction too....

[@OllyRoss]

I think it covers too much up in the engine bay on these. I like the clean look for this car. the S2000 needed one though

[@driver3490]

@@OllyRossYeah i think it's also pointless for a daily driving machine.

[@manxracer5541]

@driver3490 going off that then may as well keep the car stock ffs ha

[@JordzyBrev]

@@driver3490got a strut brace on my type r and it’s my daily, handles unreal

[@brickhead48]

Air Intake Bigger Inlet Manifold Exhaust Decat Manifold Remap to ~240hp Then get some coilovers and boom, you're sorted

[@OllyRoss]

Yeah, for a basic set up, that is pretty sweet 👍🏻

[@dominicrichardson5546]

Bought an EV1 2.0 type S a few weeks ago and I'm looking forward to building it into a 4 door type R

[@hondahondahonda5964]

I’ve already started only get partial vtec though unless you kswap

[@dominicrichardson5546]

@@hondahondahonda5964 my plan is to either swap the full A2 cylinder head on or swap just the cams and make a vtec killer. Much cheaper than swapping the whole engine

[@hondahondahonda5964]

@@dominicrichardson5546 I’d probably start with cold air induction my type s has a decat Toyo 421 and it makes world of difference next for me is the induction then eBay special splitter and skirts just for looks I guess it’s all about budget really but tbh type s is a good car I have switched out the seats and brakes stuff like that and it’s a type r on a budget hahaha 🤣

[@dominicrichardson5546]

@hondahondahonda5964 I've already got a tegiwa intake as I found one cheap on FB, might do exhaust but I don't want to be a stereotypical loud honda guy.

[@Jay-dn4pd]

Can u remember what measurements u adjusted your coilovers to? Sits really nice 👊🏻

[@OllyRoss]

I don't know unfortunately. Motion Motorsport set it all up so I just let them set it to what they think is good. My guess is that it is around 30mm lower.

[@hams2k677]

Holy fuck that spoon exhusst sounds sick af

[@OllyRoss]

I absolutely agree! Haha

[@hams2k677]

@@OllyRoss why did you change it? I have a euro r accord. I can't help but want to swap it. I have the fujibisto exhaust on mine but it doesn't have a kick to it lol

[@OllyRoss]

@@hams2k677 It was way too restrictive for power. I switched it up to gain another 30hp with the cams

[@pirotehs]

I have good tires on mine. LSD could be good upgrade. Nothing else is "must do" on this list. Stock car is good.

[@OllyRoss]

I guess it depends what you want from the car. I definitely recommend the diff though!

[@irelandshane1984]

No lightened flywheel or final drive? I have a CL7 Euro R with these and wakens the car up!! Still to map it and get exhaust and intake etc but might be worth considering. My cars a daily 👍

[@OllyRoss]

I haven't done either of them but the final drive could be up there as something too as I have only heard good things!

[@K03sport]

I think the eyeball plate delete should be on the list 👀👀👀

[@OllyRoss]

Hahahahaha! Love it!

[@muradali237]

I've got most of those things you've suggested except lsd (need a good reason to drop gearbox) and inlet manifold. It's hard to find a good inlet for a decent price these days so it's delaying me from getting a map.

[@OllyRoss]

Yeah, that is the problem with all the parts going up in price nowadays! So annoying

[@WilshysVids]

i have mine at motion just waiting for an inspection and quote ,

[@OllyRoss]

I hope it wasn't too bad!

[@eJay9oh7]

So I got excited before doing research and bought the spoon down pipe and exhaust is there a way to get 3 in headers and keep the spoon cat to make gains

[@OllyRoss]

The short answer is no... however, I am pretty sure the Spoon header has no cat in it, it's just a resonator. I don't think the 4-2-1 will make too much difference though. Adding a 3" cat back would probably be enough to see gains. Each exhaust port of K20 cylinders is 2" I believe.

[@Mgshooter]

Where can I get the power steering fluid cotton bottle cover ?

[@OllyRoss]

Mine is a Skunk2 one but there are loads of brands that make them. Just search for: reservoir sock and they should come up 👍🏻👍🏻👍🏻

[@josekanario5494]

Hola, tengo el skunk2 exhaust y no esos petardazos and dont pops like yours. I have to ECU remap for get this pops or its just skunk2 echaust?😊

[@OllyRoss]

Mine doesn’t actually pop or flame anymore, that was just one run on the dyno. I believe that it needs to be mapped in if you want it like I had it with my Spoon exhaust. It may do it without a ECU remap if you have a 4-2-1 manifold

[@josekanario5494]

@OllyRoss ohh ok thanky for your time. I'm thinking about buying the FK8. Have you had a chance to try it?

[@ItsBuster]

I'm going for Eibach Pro-kit springs. i dont want my too low as they scrape over bumps etc. What suspension set up do you recommend?

[@ItsBuster]

- can you map these and still get that loud crossover?

[@OllyRoss]

dropping it by about 30mm seems to be the sweet spot for these cars I would say

[@OllyRoss]

(I could be wrong here) I don't think you can unless you have something like ITB's. The reason the cross over is so obvious is because Honda mapped in a dip in power at the cross over to make it more obvious, this actually hurts the performance though. Ideally you want it to be as seamless as possible as that is the most efficient which means better performance.

[@babayaga5544]

Which brakes do you run?

[@OllyRoss]

I have the DC5 Brembos with S2000 discs

[@WilshysVids]

whats the total cost excluding the car payment ,, as in the restoration and mods

[@OllyRoss]

I am not sure yet but once I finish off the car, I will do a video on this very thing.

[@Playboyap]

Is this a k20a3 ? Can I put these same mods on an a3 ?

[@OllyRoss]

The UK Type R has the K20a2. I am sure it would react well to some of these mods but starting with a base of the a2 would mean you would get better results
