What injector to use???
What injector to use???
As most of you know doing a K20Z1 into my 01 civic. It is going to be all motor, nothing in the motor is going to be stock except the crank. When motor is tunned it will be in the area of 425-450HP. Have AEM fuel rail but can anyone suggest what kind and size of injector to use for my application. Thanks for the help
you should really make 1 thread and ask all your questions there because you are congesting the section up.
try searching for your answer and do more of a read up. K20A.org .:. The K Series Source . Honda / Acura K20a k24a Engine Forum is the best site to get all your information through READING
and yes the ep3 is a 2002-2005 Civic Si

you can make alot of power but bring your expectations back down to earth.
pick up some 410cc rc injectors and some plug adapters unless you like soldering. those should be fine for the hp range you will make all motor.
550cc might be overkill unless you are stroking it to a 2.3 or something

When Im done with the swap I will post dyno sheet and you will see that 425hp isn't impossible, then I will tell you how to do it then maybe you can follow.....< read with some sarcasm.
As soon as it is done I will post the dyno sheet for everyone to see. I'm not saying it will be the fastest but I will tell you it will be a beast without a turbo either. Thanks for the response guys
It is a show car, but If I wanted to drive it daily I could. You guys are saying no to 425hp, when building a motor everything you do is working with percentages, and the head is where you get all your power. And yes my pockets are bottomless!!!!! I'm 20 grand deep already not including all the custom work I have done to my car. The paint job is more then people put into there whole car, I wil post pics and the dyno sheet as soon as it is done.

The truth is that 425bhp (not even whp) is tough to acheive with a K20. I would say your best bet is starting your build around the IPS K10s (which I am not sure that they are that easy to come by now with the whole IPS deal). Now this may put you in the 300whp range, but it will by no means be DD friendly. I would then replace that 2.0 bottom end with a built k24 bottom end, because if you don't have a built, balanced, ect. bottom end with the crazy compression ratio that you will have to be running, it will not last. This and only this may put you close to the numbers you are looking for, but you will have thrown daily driving it out of the relm of possibility.

lol you its hard to even get 300whp from an N/A k20. People barely make it over that mark and it costs **** loads! not worth the $$. If you really have money to blow, go turbo. You'll achieve more with less $$
I know with the Kmes or the skunk II stage three cams along with some addtional work 300whp can be acheived. The K10s were supose to be crazy (way beyond the Kmes), but did they even run a production of them?? But I agree, it is costly. What I don't understand is if this is going to be a show car why even build the engine for that much NA power??? So you can put the dyno sheet on a plaque infront of the car LOL?? I would think that a turbo would have more "show appeal". What would be neat though is to mod the front of the valve cover, so you can look in and actually see the cams.

the only way i can see this done with out a turbo to sleeve and bore out a k24 block. make it a 2.6 - 2.7, have 15:1 compression and running nitrous... and some sick cams
as for DD, it will never be streetable... it will be a horrible ride...
and if all you have is a fuel rail and don't know what size of injectors to use, you better read up... your going to have to convert to a returnable fuel system, upgraded fuel pump... blah blah blah
if you refute what i am saying... from the deepest part of my heart, i will call you a F UCKING IDIOT...

First of all The motor is being built by a shop, and it is my father who is building it, and he has been in business for 40 years building all types of engines not just imports. So I would take it from him that if he can get 425whp out of this engine, then I know he will. second of all the only thing that is going to be stock is the crank, cause it can handle 500hp easy. So EMK20a2 I'm going to have to disagree with you. Like I said when the motor is done and the paint job is done, and it is tunned I will post the dyno sheet for you to see, then I'll send you a business card of the shop and then me and you will talk bout not being able to pull some serious horses out of this engine. And just beacuse the car is a show car doesn't mean that it won't be running down the track at englishtown during survivor series.
. I don't care if your dad builds engines for the Andretti race team he WILL NOT get 425 NA hp out of a K20Z1 with a K24 bottom end let alone a K20z1 with a z1 bottom end. It just is not happening. There are so many people on K20a that know a billion times more than you or anyone in your gene pool knows about these engines, the combined knowlege is overwelming. And these #s are laughable to say the least, they are just unreallistic with your knowledge and to think that it will be a daily driver is insane.I don't care what you post, I would not ever believe it, it is that unreallistic. It is not so much the number (however, unrealistic it may be for anyone short of having the knowlege of IPS) it is the fact that you still think it will be a daily driver

The thing that drives me insane about people like you is that you come accross like you know everything about these engines when it is obvious you know nothing. Hell I am not even sure you know anything about cars, you did not even know what an EP3 was. Trust me, this is coming from someone who has done a couple of swaps including my own Kswap; you WILL come across a problem much bigger than what injectors, or what radiator. I can't speak for any of the other knowlegeable swap members on this board, but because of your ignorance I will not help you when you post up a question.
And that type of ignorance on K20a is not going to get you much help either:

Never said I know everything bout these engines this is my first swap, But the question is that your saying a machine shop cannot get that kind of power out of this engine? Not saying that anyone doesn't know more, just saying that when it is done I will post the dyno sheet and then you will have to believe me. alls I was doning was asking a question for help, and alls you guys do is disrespect and downgrade. I don't give a **** if nobody believes me, dont' care what you think. Started off as a question and it turned into a pissing match. Guys I'm not hear to fight with you just here to learn more about the swap. Members with the most knowledge about the swaps just seem to not want to help, except for a few. Got to start somewhere right?

lol... is that a threat... come on, if the pro teams that have over 20 g's in a NA motor can't get much over 350hp what makes us think that you can get 425?
i don't ask many questions because all i do is research... read read read... that is the only way, seeing what people have done. what has worked and what has not is the only way to see what you can do.
if you have certain goals, many may be attainable with a certain plan. you don't need over 300 with a light NA car to get into the 10's or 11's
if i were you, i'd listen to me... i know more about a K than you will ever know in your life time...

I am not disrespecting you because you are asking questions, I think that is great. I really like helping people out. After all who was one of the 1st people on K20a to point you in the direction of a radiator?? What drives me crazy is that you are asking us for help on simple stuff, and then when we try to bring you back to reallity about what this engine is capable of and you act like we have no clue. You need to be a little more humble and less ignorant, and maybe we could point you in the direction that you need to go to get close to the number that you are looking for.
I was humble and was asking questions, and yes you did help me out and I appreciate that, and yes you know a lot more then me about the k-swap obviously this is my first k-swap. I'm just telling what the machine shop told me bout this engine, that he could get double the poweer out of this motor. He just didn' tell me right away that he could get this power, he researched and called many people in the business about this engine. I'm just telling you what he said he could do. I'm not ignorant every bit of info that I recieve from any member I appreciate and thank you. The disrespect part of it I'm not cool with.
you know what though.. you posted on k20a.org that you stated you were doing this with nos.. then i see the post get deleted?... so where in all this does it say that you were going to use nos.. i dont see it in your first post.. dont see it in your ..
its like emk20a2 and hondaluver and everyone else on here and k20a.org is saying.. you gotta read more into it before you say something.. i have been up there along side K20 motors since they first came out and been researching into it everyday since then. I aint saying i am a big shot person who knows everything.. but when you got big companies like IPS, skunk2, and import builders and many more not even hitting those numbers on there fully built motors then that has something to say. The day hasport debuted the mounts to put a k20 into the EM2's, i called and ordered them the next day. Did the swap. and made a do-it-yourself write-up on how to do the swap, even went as far as how to wire up the engine harness yourself.
Using nitrous as one might call it is no longer considered the ALL MOTOR category. Its considered part of the turbo category.

And even told me that the RSX radiator will fit right in
. JK
, no your DIY and posts have done alot for this swap, there just must be something a bit different about the radiator fitment from our years/models because that was a b!tch LOL
Yes double the power may be somewhat realistic, but that is 420 crank hp which would equal roughly 350whp. This is a far cry from 450whp that you are claiming your car will make. 350whp would still be hard, it would be on race gas and it would not be a car that you would want to drive everyday.
you have on 04-05?? cause in the 01-03 the only mod you had to do was trim around the radiator cap area.. well thats all i had to do when i used the rsx radiator
