After 10 hours of bitching and bleeding im done with the head swap. I ran into a few problems like getting the timming right, having the gasket for the vtec soleniod leak and forgetting to plug back in a sensor. Over all it was pretty easy just really time consuming. Im running a vafc2 for the vtec instead of a ex ecu and i set vtec for 4700. The cross over is alot more then i expected. Its pretty loud and i deff feel a diff. I know it sounds kinda dumb from a sohc vtec but its alot more then i expected. I would deffinatly suggest this mod to any dx/lx owner. Ill get some pics up 2morow of my vafc2 mount and the engine bay.
By the way im throwing no check lights and it runs very smooth.

nice and a few suggestions for ya.
put the vtec at 4200rpm
and make your wide throttle
pre vtec engagement at about -3/-4
and hi cam engagemnet from 4200 +3
4600 +4
5000 +5
5400 +6
5800 +7
run +7 all the way from there
im running the same setup and it runs alot better
and run your precentages at 30%/80%
workoff that and tune to yours it'll help and feel better. you won't be running so lean at hi cam engagement.

wishs omeone would smack up a vtec roudn ehre. but no one has yet lol nothing in our salvages..

if i can salvage and ask for teh header off a civic ex 01-05? will this work? thats all i want to ask for is a vtec header?
i would got for a ecu but think i would need a new harness right?

Header is a exhaust manifold, you want the complete head. Running the VAFC2 seems to be the easier choice than getting a new ECU and having it reflashed to accept your keys.

I found the head on this site from cardnoff (the y8 intake mani man)

Its a great mod guys just make sure you know what your in for and expect your car off the road for a full day or 2 at the most.

Im going to take some pics now

iTrader: (2)

that still looks like an lx intake why is that?

iTrader: (15)

It is my old dx intake...if you look the mounting braket is just dangling cause the mount was replaced by the vtec soleniod

I like the color scheme on the valve cover and wire cover.

very nice

dx/lx/ex....all the same intakes when it's a short ram.
It's just a head swap nothing is changed on the intake manifold/throttle body.

Very nice. Id like to see a dyno of an LX vs a LX w/ Ex head swap. Thinking of doing it sometime... ( even tho my mom wil rape me after the $$$ i poured into my last cars engine but the stock engine just sucks...)

Id like to see wat a LX/Vtec head with I/H/E and a crower cam would run... think thats gunna be my setup after i get outa school... maybe some nitrous...

joshb_

iTrader: (15)

i would do crower cam but that would involve taking the head off and putting the cam in, then putting the head back on with a new head gasket....to much work and money

I though I read something about you having trouble with the exhaust? Was this you and if so how did you fix it?

joshb_

iTrader: (15)

No trouble with exhaust...right now the stock dx on the ex head but im going to dc sports tsc cat back to a dc sports header probably

stepchild

10-4. Ive searched for info on the LX to EX header swap and a lot of people said that they had to cut part of the engine mount for it to fit. And I also red a lot of people were not too pleased with the performance of the DC header. Personally I dont know but you might want to ask some people about that.........

First time I did the swap (EX OEM head to PNP EX head) it took 12 hours by myself. Second time I did it I pulled it off in 4. The best way to keep timing is ziptie the cam gear to the belt (which only goes on one way anyway due to the key). The most pain in the *** part are the intake bolts and the bracket that holds the intake on (accessed from under the car). Thank God I had a lift the second time. Oh, lining up the gasket with the plug for the oil galley is also a pain in the ***. Thats a lot of dough for a gasket. I have friends who work there and I snagged intake AND head gasket for $35 after tax, so retail can't be THAT bad. Although the head studs are stretch bolts I reused mine twice with zero compression issues.

HAHA i didnt even put the intake mani brakets back on waht a pain in the ***...its a plastic mani so it dosent weigh much im sure the hoses and acutally bolts that go in the block will hod it just fine

Rufus

iTrader: (17)

Probably. Could you believe it's plastic? lol What a piece of shi+. The middle bolt on the intake was a bitch. I used one of the self ratching box wrenches.
