turning non vtec into vtec

[02ZZI]

Hello,
I hope i have been reading right and made the right assumptions. I have been reading a few us forums turbo d and d-series. Anyways i have been reading that they have been putting sohc vtec heads onto non vtec blocks calling it a mini me.
I had no idea about this to the other day. Am i reading right?
Its hard for me to understand because they have different engine codes dont they?
Anyways i have a 99 ek1 hatch i think my engine code is d16y4.
My goal in my car is to turbo charge it and make around 130kw atw's before any serious internal work.
I have been told that turboing this mini me is good because you get a longer rev range plus vtec with boost?
Can some one help me clarify that i am on the right track here?
How much could this conversion be done for and what are the nessecary parts required?
I hope i havent made a fool out of myself.
I think i got everything right there
thanks for your help.

d16y8 head will mate right up with that block. Then all you need to do is wire in the vtec. I believe you might need a new ecu as well? not too sure on that though.

If your going to boost i wouldn't bother with the mini-me. If you do want to go ahead with it you might as well build you motor to begin with.

what he sed ^^

boost the y4 man, any dseries kit will fit.

[ECU-MAN]

you will need to do something with your ecu, as you need to change fuel and timming for the ner cam shaft as well as activate the Vtec solenoids

[02ZZI]

yeah what i thought was new head and bolts with a ecu?

[sivic]

a guy here in perth has done the mini-me swap recently and is using the ECU from the D16Y1 (SOHC - Non Vtec). you'll need an ECu from a D16Y8 as its OBD2. this works fine but there are big improvements to be had.
he did his in an EG so its a D15B block with D16Y1 head. it ended up bumping the compression ratio to around 11.0:1
but you'll need a new stand alone ecu once you turbo it

[02ZZI]

does anyone have any idea how much it would cost?

[civ_sik]

too much just do what everyone else says and turbo your current motor.

[sivic]

a mini me swap is cheap. the guy here did all for under $1500 parts and labour inc a head recon. its now as quick, if not quicker than a vti or si. and the response is excellent due to the high comp ratio.
bang for buck its a pretty good mod.
mind you the comp ratio might not be as high for a d16 so it could still be suitable for a turbo conversion

[turtleEK1]

just force feed the engine as is...

like sivic said, your compression ratio will go up if you do the mini me... but you want a lower comp ratio if you go turbo charged tho! prolly around 9.0:1 i think? plus tthe money you could save from doin the mini me could go into a better forced induction set up!

look up some turbo d-series setups from the states, some have been pulling good numbers with stock internals!

[sivic]

yeah, if your going turbo the cost of a min me would prob cover a new camshaft, camgear and valve springs. and maybe a slightly thicker headgasket. pretty sure crower make camshafts for turbo applications

Hmmm....this seems to be what I might be thinking of doing. Can anyone point me in the right direction to get more information regarding this 'mini'me' conversion.
Is there are a lot of components and labout involved? I noticed 'sivic' mentioning someone doing it for like $1500 inc parts and labour.

Thanks in advance for the help and info. :D

yer im very intrested in the "mini me"
i was thinkin askin the dude at honda care in "brisbane" at summer park can do it.
i heard he really good at honda's and lots of information

so basicly wat do u need to get for the conversion?

can i get the d16y8 cams into the d16y4

search it, theres alot of info on mini me conversions

[Mugen_B16B]

isnt OBD2 from the 99-00 models?? i thought it was OBD1?

[Olskool Integra Boy]

that sounds good, im guessing similar could b done to d16a?

should also make sure you get a dizzy according to the type of ecu you use.
ie.
obd0 ecu with a obd0 dizzy
obd1 ecu with a obd1 dizzy
obd2 ecu with a obd2 dizzy

otherwise u'd run into problems
