LX engine convertion to EX VTEC

Hey I always got depressed for a long while because i couldent really make my car fast because i didnt have the infamous vtec ex egnine. So i give you the solution. The only diffrence between the ex and lx and dx engine is the head. The block is the same. So i am in the process of buying the head of a ex that they are selling at an auction for parts. All thats needed is the head for the engine and the ex cpu. The Head runs new for 1.2 grand plus the ecu. Its also very easy to put on the cpu will be the only hard part. It can be found for 1.2 grand here:Majestic Honda
I am going to try and do this and let you guy know how it turns out. It is not very expensive and allows you alot more freedom in your upgrades.

Unfortunatly it doesn't matter if you have the VTEC engine or not, they are both very slow. In fact, Civic's in general are slow. Even the WAY overplayed SI is what would be considered a slow car. I'd save my money and work on the looks of your car. Those can actually be improved.

I know, I could easily buy a sports car thats not my intention. My goal is to make my civic, the car I have fast. One of my friends allready ran a 13.1 with his 2k1 ex, thats fast. Its a hobby, people always say why do you spend so much money on your car why do you work on it so much, because I like doing it. Besides whats the point of having good looks without being able to back it up.

13.1 sounds a little fast to me, even with a large shot of nitrous. Either he has done some serious custom work with turbos, or his car will only last another few miles

Somebody sounds pissed off.[IMG]i/expressions/laugh2.gif[/IMG] Face the facts, an SI is NOT fast. It can be made fast with $$$, but then again, I could make a geo metro run 8's if I had the loot. I'm not trying to start a flame war (hell I have a 2k2) but show me a 13sec SI and I'll show you 30 13sec Mustangs, Firebirds, and Cameros. People are dilusional about Civics. Yes, they are 'quick' for econo cars, but fast....no

its way to easy to make a domestic fast..."wow you have a 11 second firebird!? howd you do that!?"...its all too common and i cant respect it very much just cause much work isnt involved. now show me an 11 second civic and THAT thing deserves respect. thats just my opinion though, its my style.

For got to mention that you will also need a new air intake (throttle body and such) found here:Intake manifold. And for dxman:

Those cars you mentioned also have massive v8's. I sure hope u can find more v8's than can run 13 sec 1/4 then civic. Also it's the challange of bringing out everything out that the motor can dish. I dont hate on import or domestic, i like em both, but if you have a v8 i feel you should be running around 10 and not 13s like a little 4 banger. You dont seem the type of person that would want to do this mod anyway due to the fact of how pessimistic you are. Why dont you go make your car look pretty.[IMG]i/expressions/face-icon-small-wink.gif[/IMG]

I wont be paying 1200 for this prolly around 500-900 because im getting everything at a dealer auction. Selling this 2k1 with a broken axel that they dont want to fix so there selling it as parts. Also it is worth it in the long run also because the ex motor is alot more upgradable then the lx/dx. I sudjest this mod for any lx people that are serious about making there car fast. Also picture this: Go to the track comon race me I only have a lx, little to none people mod them because there motor pritty much sucks for racing. But wait you have the vtec with a shiznit load of mods and vroom vroom eh?

Also avenger I know its just the fact that its alot more upgradable then the lx, and has alot more potential.

think for a sec though, if all you are replacing is the lx head with an ex then you still have an lx car, with an ex head.... parts made for the ex such as exhausts, etc, dont just bolt to the head. The lx exhaust piping is different, the cat is different.... think about it. by changing the head it is not an ex motor, its an ex head on an lx d17a1 block in an lx car...

The lx's compression ratio is friendlier to fi so you can run more boost when turbos finally come out and that would make you fast imo save the money and get 75hp later for 5gs and not 10 for 1

I agree, there is something to be said about making a &lt;2 liter car do a 13, but my point was that it isn't worth it in the long run. And my *original* point was that converting from a LX to an EX motor seems like a waste of money at almost any price. First you void your warantee, second you reduce the life of the engine. Two things that I don't see any need to do for what, 12HP especially since making it more 'responsive' to mods means at best 10-20 additional HP. Even with a turbo, which may or may not be available, I don't think the 2k1s will break the 15 second barrior. If you think that is fast, I can point you to 100s of other cars on the road that can do that stock. Most without big V8s.

As for the 2k1 doing a 13.1, I'm VERY dubious. IF it is true, I and alot of other on this site would love to know what, where, and how it was done. Until then...

Someone else getting mad at a statement based in truth. Don't assume I have a DX because of my moniker, that is based on something other than cars that I don't feel like discussing right now. Speaking of hating, don't hate DX/LX/EX because you have a superiority complex from your Si. It does have more potential, no argument, but potential for what? A 14 second 1/4? That ain't amazingly fast, certainly not enough to warrant rude and condescending remarks.

The dude posted to a message board for <font color=white style="background-color: 3E3E3E;">OPINIONS</font ft> about his conversion from LX to EX. My <font color=white style="background-color: 3E3E3E;">OPINION</font ft> was that it wasn't worth it in the long run or in the short run, especially on a new car that will be very reliable if not messed with.

Dude our cars can do 16's stock....

NOS..shave off a second or two, I/H/E/ you'll shave off a tiny bit, turbo that, and you'll take off a second or two, etc. Someone on this site has done a 15.8 STOCK, and he has a video up of him doin it.....I think you need to be put in your place you freakin NEWBIE!

How am I hating? I own an EX. Yea your opinion for it not being worth it is true, but saying the Si is "slow" compared to other Civics is not. Compared to other "sport" cars, hell yea, its slow, but im sorry some POS hatch running a D block not even 100 horses to the wheels is not gonna touch an Si.

Ok, I know this has probably been asked, but it's relevent in this thread, but would an EX header and cat bolt onto an LX block? If it's the same block, I don't see why not. If you could find a junker or auction car, than there's your solution to EX parts if you can get the cat for cheap enough...

I would assume it would work

with b series parts it works with any b series so Im assuming the d block would be the same

yeah the block is the same. I think we should just leave dx alone i asked for opionions and he gave me his and is just in doing so, just because we dont all agree with it or dont like with hes saying lets not get hostile. So If i were to get everything for 1 grand you guys dont think it would be worth it? Wait so what your saying is that the hp racing headers would hook up to my block i would just need a new cat right?

Well, if it's right, you could get any header you want, HP, DC Sports, even the stock EX, and just bolt an EX cat on to it, then you could get an exhaust made for an EX.

Again, not starting a flame war, in fact, I've been peaceful in my replies...but...

-Nitrous (not NOS) at 50 shot or so which is about what the stock engine can handle might shave a second, but not two.
-I/H/E got what 7HP in whatever mag dynoed it. That is maybe a tenth of a second
-Now, if you got the ***** to run a turbo on top of the nitrous, you *MAY* break 15 but only by a few tenths. Your car will feel the abuse however, and you'd be better off with a stock, bleh, domestic V8 as far as reliability

Now, I would love to see it happen (I own a 2k2 remember), but I'm a pragmatist (not pessimist as previously stated). But if you put all of this time and energy into a Civic, what did you really accomplish: an unreliable, almost un-streetable, probably un-smogable, expensive econo car which can still be beat by a lot of non-race cars stock. Until someone proves me wrong (are you listening 13.1?) than I think my opinions are fairly valid.

DxMaN: Man you crack me up! You suck at draging huh? Did you not even pay attention? A dude from this site did a 15.8 STOCK!

What does that tell you if you slap some mods on a 7th gen?

I think this thread is getting outa hand to some degree.....by the way my bad on the "NOS" I usally say Nitrous or N20; must have slipped that time.

Anyways if you can drag really well, what makes you think that someone can't break the 15's with some mods? You gotta be kidding me if you can't break 15's with N20, and I/H/E.....I mean so what if its a 14.99? It's still 14!
