i have a stock motor 1.6 singleheadcam from a 98 civic dx i want to rebuilt it from stock to vtec 1.6 singleheadcam just need some instruction what parts would i be needed to built a 1.6 vtec singleheadcam n do i need to change my stock transmission pls need help

parts that will be needed;

1. 1.6 vtec head (d16y8)
2. chipped ecu ( p28 d16y8 programmed)
3. wiring harness for vtec
4.fuel injector
5.
6.

You will need a d16y8 head. You can keep your transmission, even though the one from the y8 is better, so its up to you and what your budget allows for.

you more or less just need a vtec head and a chipped ecu and i think you run a stock p28 vtec program... you need to wire up thr vtec as well... its called a mini me swap and has been covered numerous times on the boards. i have a 16 page written and illustrated DIY writeup im sure i can post the link for... just let me know

oh and of course you can keep your tranny but the tranny from a y8 or z6 would be much better.

mikepasini can u give me the written page and the links pls thanks

I gotta ask, is doing something like this in any sense worth it?

The cost of buying a vtec head, gasket and labour can't possibility be worth it!?!

imported_mikel_raider

no problem about the labour coz me and my cousin a maechanic from a shop in toronto will built the engine

imported_Cablerat

^^ Right but time is still money, everything considered.. I find it hard to believe it's worthwhile .. anyway, sorry going of topic.

I think its worth it under certain circumstances. For example if your going to build a fresh d-series and prepping for boost, with new rods, pistons, and what not, then you might as well get a vtec head, or if you have a vtec head you can swap to a stronger block like the a6.

But if your doing this because you want a little more oomph, I think there are other solutions. Then again, if he can do it himself, then he saves on labor, which is where most of the money goes anyways. Parts for D's are pretty cheap.

I have a p2p ecu, y8 head and a y8 intake manifold thats pretty much all you need to do the vtec swap.

Make an offer. has 135K on it all.

And I think its worth it. my friend did it and with the stock p2p ecu I think he had 121whp with bolt ons. All stock (i honestly don't know how it happened) but it did.

The VTEC head swap makes sense if you want a greater camshaft selection (i.e for boost or nitrous).

if you're gunna use a chipped p28 you will need an obd2-obd1 conversion harness.
Personally, if you are going to use a D16y8 head (which i would since you've already got an obd2 car) i would use a d16y8 program instead of the p28 (d16z6) program.
The head swap will yeild minimal gains, i'd be more interested in getting a SI tranny and a lightweight flywheel, without the SI tranny the head swap isn't going to make that much of a difference.
But if you're gunna swap the head and tranny, why not just swap in a complete d16y8? It would be less work IMO.

what is a d16y8 program?

like are u just talking a virgin ecu ...not chipped

zeeman

iTrader: (1)

well a virgin P2P ecu, like chris has, will prolly be ok. But if you want any sort of tunability (changing rev limit, vtec crossover, speed limit, etc etc) use an obd1 ecu (chipped p28) with a d16y8 program on it (i can provide you a program and ecu if needed).
I suggest the d16y8 program b/c it has different fuel/ignition values than the d16z6 (stock p28) program, and will be better suited for your application.

i have a stock ecu for a d16y8 ...so wat cud be done for me?

chris_si98

you use that ecu with the y8 head and IM.. everything will be good

zeeman

Nothing, you can only really chip obd0 and obd1 ecus. Chipping obd2 ecus is very expensive and not very many people do it, b/c not too much is known about obd2 code right now.

well...hmmm i suddenly have some sort of a hate for obd2's...maybe i'll just get some management of some sort to mess with

chris_si98

yeah who needs emissions and to stay legal anyways

Tyson09

i do apparently ...i just bought some tune up **** and some emission passing formula (kleen flo tko 2000) jesus i felt like i needed a license just to buy the stuff with a name like that

honestly, converting to obd1 is your best bet. Any sort of "management" is gunna be either very expensive (standalone) or just a piggyback system (apex-i vafc, greddy emanage). Piggybacks are a waste of money IMO, since they just trick the ecu into thinking the engine is running under different conditions, and usually have a negative effect while trying to deliver more/less fuel (ie ignition timing change while changing the fuel).
For the $250 you'd spend on a conversion harness and chipped p28 you'll be much better off than trying to mess with a vafc (vtec controller). Not to mention, completely setup for when you decide to have your car tuned (with crome/hondata/neptune). Except with hondata/neptune you have to purchase the hondata/neptune unit, where crome is free. With crome you just pay your tuner to make you a custom program (street/dyno/track tune).
Before attempting to mess with some management (as you said it) i would highly recommend getting a wideband o2 (so you can know what your air/fuel ratios are) and have a solid knowledge of how an engine works and at least a basic idea of tuning fuel/ignition values and the consequences of your actions.
