im asking because ive been looking around and im not really finding any si that is reasonable, so i figured id explore the EX with swap option any input would be great thanks

EE_Chris

If you found a reasonable Si, what engine would you put in it?

Libertariat

i c wut u did there



The important question is budget, know how, etc.



If you're budget is unlimited I'd tell you to put your civic on top of a subaru frame/suspension/engine.

If you've got $600-1500 I'd tell you to leave your car alone.

The best swap is a J series V6. The best power for the money is a built D series (stock engine rebuild) on boost or a boosted stock block. The worst power for the money is a K series swap. Followed by a B series swap (unless you have some crazy hookups).

what?^ the truth is that modern engines with dual (or quad) variable camshafts can spool a turbo quicker while generating more top-end power than a single cam enigine. running more than one camshaft enables twin cam engines to fill the cylinders with more air (or boost), and run cleaner and more efficiently than ever before. that's a win-win for the b, k and j-series

He said "for the money".

i wasn't talking to the guy who started the thread, sorry for not answering your question Mims3Id, i would atleast start with a ls or b20 given their fairly cheap setups for daily's but if you can afford it i would go with a gsr or type r engine

Jimster480

They are not that much more efficient. They only spool turbos faster because they come in bigger sizes compared to Single Cam engines. And quad cam engines are where? A DOHC V6 doesnt become a quad cam. While DOHC's are better than SOHC, there is no night and day difference. And having more than one cam doesnt allow you to fill cylinders with more air (and boost is also air, just compressed). The size of the cam,duration of the lift, size of valves and ports are what determine how much air can flow in or out of the cylinders at one time. And J series isnt DOHC, its SOHC. A GSR/Type R swap are FAR from the Best available swap for the car.

There are always pro's and cons of each type of swap. You cant just say that a J swap is the best swap... What about hood clearance? weight? downtime, amount of fabrication required, etc.

And I have seen turbo D builds cost into the thousands, and K-swaps done pretty cheap. You shouldn't make such generalizations about builds. It really depends on your application, budget, and skill. There is an infinite different ways to making power, that's the beauty of Honda's.

Js might be nice money wise but if it was such an easy and best build there'd probably be more of them. clearance ground or hood is kind of a serious aesthetic issue for a DD.

i also don't think honda's have quad cams...not sure on new ones. usually thats a ford, chevy, dodge thing.

Jimster480

Well when I said best. I was saying it from the perspective of the most power out of the swap with no modifications.

What are your power goals?

If you have a little time and space I say buy a crate D-series and re-build. For a good boost application all you need is pistons, rods, rings, springs, and retainers. Keep it simple.

This is obviously more than you need but it's proof that D's can make power. You don't need the P&P, TB, IM, ect. Just keep it simple.

i want something that wont take too much of my time im in the army so i dont have very much of it. i like the idea of a boosted d series. i would like somthing simple its my first build and id like to do as much of it as possible myself. and for power goals im just looking for somthing that i can use as my DD but not feel like im driving my wifes LX (everytime im getting on the interstate i feel like im gonna get rear ended trying to merge ha)

Red_Army

then I'd say just boost the D. pretty easy not very time consuming and relatively cheap.

mechanix619

Sounds like a boosted D is your best bet. They are easy to come by and overall cost will be low so you can put money into turbo.

92civlude

Anybody heard of H22?

mechanix619

More work then they are worth.

92civlude

Mine was easy!

WhiskeyD

K series is worst power for money? Get with the times, you find find K series for pretty cheap now days. And I would never put a J series in a civic, they belong in accords and integras imo!

dc2_dustin!

agreed i'd have to smack you if you did a j swap lol but unless you have a hook up or already have a k ready shell imo a kswap is a wast..can't beat b20/b20v

b20hatchek

and ive worked on j-series before lots of times and their quad cam jimster, that's why when you look at the plastic cover it says DOHC vtec

bkopel805

If your trying to go cheap, I'd look into an LS or even a B20. Both are fairly cheap and put out decent power. Even boosting the D isnt a bad idea. My ej7 was boosted for a while on 5psi.

b20hatchek

thank you except on the last part, d's just aren't my cup of tea haha

mechanix619

I know it's been done with success (those that are built correctly with aftermarket rods ect) but I don't like boosting the Honda engines that have an 89mm stroke. However, if the engine is only going to see 5-8psi I could be tempted. I say D-series boosted for cheap and easy.

b20hatchek

i agree but with a boosted ls you dont have to rev it up at all to light 'em up
