how to do mini me
ok i have the 1.5l d15b7.... is the mini me putting the vtec head on it? the d16z6? is the mini me better than just putting the whole 1.6 in? Also would it help if i built up the z6 head like camshaft valvesprings and retainers? Also if i did that would i have to build up the block.. pistons rings rodss. ect... What kinda gains am i looking at? Now i here talk about this oil jet stuff. what is it and what do i have to do with it? What are all the connections i have to hook up? can i use the d16z6 ecu with the 1.5 liter block and the 1.6vtec head? i heard 3 wires need conected off the vtec seleniod which ones and where do they get hooked up?if i get the 1.6l head should i use the 1.6l intake manifold and throttle body can i just use the 1.5? I have the basic bolt ons and am looking for more power by doing the mini me please help... Thanks. Brian

Re:how to do mini me
i'd say try the hole 1.6.

From: "Chris Fitzpatrick" <chris@t...> Date: Sat Nov 30, 2002 3:15 pm Subject: Re: [hondalist] Gonna swap a Y8 o to a Y7, need advice on ANYTHING.. below is the small writeup ive done for a mini-me swap... word of warning.. if the y8 head is a 96-98 and the y8 intake manifold is a 99 or 00 you will need to plug up the injector breather vents (i used permatex) or else you will have a major intake manifold leak. Here are the parts you will need: y8 head / intake manifold / throttle body / ecu etc.. basicly everything head up from the y8 you will need to get a knock sensor since the y8 ecu expects a knock sensor and y7s didnt come with them, i would try to find one used since from honda they are around $150 new, there is a port this screws into on the back of the block right above the oil filter near the top of the block (its pre threaded). you will want to do this and run a wire for it before you put your y8 head/manifold on since its near impossible to get to. as far as wiring there are 6 wires to deal with: 1 for knock sensor (1 pin, must be added see above) 2 for vtec pressure switch (2 pins) 1 for vtec solinoid (1 pin on usually green plug) 2 for idle air control valve (canister hangs off back of y8 manifold near throttle body with 2 pins) you can either try to move the wires in your y7 harness or just run new ones (you can feed them through the boot under the battery holder), since I couldnt figure out how to remove the pins from the harness and relocate them without destroying the plug or pins i decided to just run new wires. this way you can just plug your y7 ecu back into the harness later on if needed without redoing the wiring again. 4 wires will need to go inside of the car to the ecu, 2 are connected to things in the engine bay in engine bay wires: -one of the pins of the IAC valve, goes to the middle pin on the y7 iac valve connector, the y7 has a 3 pin connector the y8 has a 2 pin, the other pin from the y8 iac will run to the ecu (see below) -one of the pins of the vtec pressure switch needs to goto a good ground, the other pin runs to the ecu (see below) from what i can tell it doesnt mater which pin on those two connectors goes to the engine bay connection (above) or ecu connection (below) in ecu wires: here is the pinout for the 96-98 ecu's http://tech.hybridgarage.com/tech/6g...les/EKpinA.jpg (A/32p) http://tech.hybridgarage.com/tech/6g...les/EKpinC.jpg (C/31p) http://tech.hybridgarage.com/tech/6g...les/EKpinD.jpg (D/16p) -the wire from the knock sensor will goto pin 6 (KS) on plug D/16p -the wire from the vtec pressure switch will goto pin 15 (VTM) on plug C/31p -the wire from the vtec solenoid will goto pin 8 (VTSOL) on plug A/32p -the wire from the iac valve will goto pin 12 (IACV) on plug A/32p i soldered the wires to the pin connections in the ecu (notched a hole in the ecu to run the wires into it) other than the wiring there isnt much to the swap, you just remove the y7 head, put a new headgasket down then put on the y8 head. just make sure to follow the procedures in a maintenance book (haynes manual recommended). if you are going to use the y8 exhaust manifold/cat you will need to extend the wires on the second O2 sensor and then get your exhaust modified to mat up to the cat (dx exhaust at least on the sedans will go to far forward and about 10" needs to be cut off for the ex cat to fit under the car) -Chris obd1 is pretty much the same ----, only you use d16z6 parts instead of y8 |
Re:how to do mini me
that is very good...... do you know anything about the oil jet in the block that needs removed or anything where exactly is the vtec selinoid.... is it like a relay or what?
|
Re:how to do mini me
the oil jet is on the block middle back under the head between 2-3 cyl.. pull it out with needle nose plyers.. and as for the vtech solenoid it should be on the back passager side of the head with 1 wire.. it needs a 12v constant when the car reaches a certain rpm u can use a rpm activated switch or get a apexi controller for $300 id go with the rpm activated switch and a relay for like $50 or so total.. :) i have pics of the whole swap ill try to find them..

Re:how to do mini me
can u find the pictures... i would def. like to see them..... im sure alot of people would actually. o yeah what is the ruff estimate of hp when doin the mini me swap... and what is there to do to add more hp to it if you cant turbo it? Nitrous? other than the bolt ons.... like headers upgrade fuel and and spark.... anything? thanks Brian

Re:how to do mini me
what year is ur 1.5

Re:how to do mini me
just put the ---- on there and blow it up.!! yea yea!! :)

Re:how to do mini me
use the 1.5 bottom,when you put the z6 or y8 head on a d15,it raises the compression quiet a bit. the y8 is a better head because the compression ratio (cr) will be slightly higher. check out this d-series compression calulator
http://www.knology.net/~jediklc/ the z6 head + d15 bottom = 10.1-1 cr the y8 head + d15 bottom = 10.52-1 cr the z6 head + d15 bottom w/2 layer head gasket=10.86-1 cr the y8 head + d15 bottom w/2 layer head gasket=10.41-1 cr the d16y8 stock = 9.6-1 cr the d16z6 stock = 9.13-1 cr |
Re:how to do mini me
woops i wrote the 2 layer gasket cr backwards
