R18A1 Part List

Always positive first then negative, and when you put them back on negative first

Actually it's Negative then Positive when removing the battery. Positive then Negative when hooking up a battery. You will get less sparks/arcing this way. You can just disconnect your Negative side only if your not removing your battery but wanna kill power.

This order holds true especially if your disconnecting something on the car with the battery still hooked up (amps/lights/etc).

Reason being is the Conventional vs Electron flow theories.

Someones explanation of the 2.

I could try to explain it in my own words for someone who can't grasp it but I can't say i'll do that good of a job.
 
so will the r18a1 parts fit r18z1 for 2015 civic? i read it would but didnt know for sure
 
Yes. 90% of them fit. Parts availability should be pretty close to identical for your car anyway so just check and make sure before you buy something very specific. You looking for anything in particular?

For example the 06-11 has a dogbone torque mount on the passenger side of the engine and the 12+ does not.
 
mainly just bolt ons its the wifes daily. header, air intake tb spacer. i seen skunk2 has a nice header
 
If its the wifes daily, DO NOT DO THE HEADER! Unless she likes a really really loud car.

(the header is technically a "test pipe" on this car. It replaces the catalytic convertor so if you need to pass emissions the car will not pass with that "header')

Intake and TB spacer should work fine from 8th to 9th.
 
whats going on! new to this forum and was wondering if anyone has done any other mods to their engine? im looking to do some soon

Welcome to the site. What are you looking to do?
 
I am looking to do some bolt on mods ie intake, header, exhaust. Im new to the 9th gen and really haven't worked on it much. So just looking for advice. its a four door ex automatic
 
Good morning everyone.... So I was thinking of not doing much to my motor since I drive an ex. After thinking of it I decided I was going to start. Over the weekend I threw on a cold air intake and the difference is amazing. The amount of space you get after taking the
stock intake out is insane. Next MOD header and exhaust..... Any ideas??

You really need to look into hondata flashpro or ktuner and a custom tune from vitviper. Your car will start adjusting timing/fuel as you install mods which will negate any gains you get from aftermarket parts. You'll need to be tuned to see gains.

the car will adjust to itself has I put mods on is what you are saying? what would you recommend doing? I am trying to stay in the cheap range lol
 
It will. Your only option is having it tuned with one of those options above. Otherwise it's truthfully really a waste. You'd be better off getting lightweight wheels (for reduced rotational mass) to make it feel more powerful. Otherwise it'd be best to do suspension upgrades. The si is basically the same way. Upgrades really require a custom tune.

thanks man I will look into it. I have already lowered it and did some cosmetic work for looks, but defiantly could use some good light weight rims. I will continue to do the MODs for now and get this thing tuned. when I bought this car I heard a lot about the flash pro and the upgrades. its not your normal 2000 civic lol. but again thanks man
 
Good afternoon. I own a 2013 Honda Civic Sdn EX 1.8L I4. My car is all mine now, so just looking to make some changes to it. I am planning to get the Skunk2 Tuner Stage 2 Camshaft (https://www.skunk2.com/shop/engine/...-series-camshaft-305-05-0205-305-05-0205.html) and Hondata Flashpro. However the camshaft looks like its only been designed and tested for 2006 and 2011 Honda Civics. Has anyone gotten this? If not, do u have any other suggestions?

That link you posted are for the H22A and F20B engine. You have the r18z1 engine. Honestly, I would not even bother with cams on the r18 engine. There were people who did dyno tests with these cams on the r18a1 8th gen (and they were tuned) gaining like 7 wheel hp. It's just not worth the money on the r18 engine in my opinion.

Sorry, my bad. I wanted to post this: https://www.skunk2.com/r18-tuner-series-camshafts-stage-2-305-05-0075-305-05-0075.html (copy-paste error)
Anyway, yes nothing much to gain, but as long as nothing to lose, I just want to give it a try. If it will fit, I will try it on. I am not looking at an earth-shattering performance, just a little bit of difference after 12 years! Thanks @webby

I’ve not seen anyone with the r18z1 engine try those cams. I would reach out to skunk2 to see if they can comment on them being used in the 2012+ engine without issue?
