a6block z6 head

[INJEN78]

ok soo have a d16a6 motor in my 91 si hatch..the head was fucked up when i bought the car soo i bought a d16z6 head and a d16y5 head..now my question is..what do i have to get for the d16z6 head to work properly with the block...lie timingbelt,sparkplugs or will the timing belt from an a6 work??

You need to get a head gasket of course to put it on.

Theres an oil control jet on the A6 block you need to remove between cylinders 2 and 3 when the head is off. Top of the block towards the firewall.
Also the timing belt, Use the appropriate one for the head. Z6 - use the Z6 belt if I'm not mistaken.

This is known as a "mini-me". updating the car to obd1 may help but there are other ways to get this engine to run right. I'm not looking for a thread on this right now though.

yea i know its a minime...but do i have to convert the car to obd-1???i am just looking to get the car running for now..soo that i dont have to buy another hear(a6)..i dont care if vtec works or not..im just tired of walking or finding rides everywhere

you can just run it on your current pm6 ecu under obd0 as long as you still use the a6 distributor. make sure it bolts up right before you put the head on with the right orientation. I heard of one person that ran into this problem, but they may have just been retarded.

Swap your injectors from your old manifold to the new one, or just use your old one, but I believe the z6 one flowed better, the y8 flowed best. Keeps you OBD0 until you can convert it to OBD1 or until you can get something to tune it. Of course Vtec does not work with the PM6, but it should at least run.

ok soo i did some research based off of what you have told me...and i am going to be using the z6 head with the a6 manifold,injectors,and dizzy..will vtec work if i hookup an RPM SWITCH??

yes, but you will not have the fuel maps, and the car will likely run lean in this situation. Not recommended at all, but it can be done. You can even make a push button to engage it if you want for an even cheaper method, just as effective.

I myself chose to convert to OBD1, it really isn't all that difficult if you can source the ECU Distributor plugs from a junkyard. But it is a lot of time and work when you can just buy a harness.

ok so what would i have to do to have the correct fuel maps??new ecu?new injectors? and also i dont know if it matters or not but i have GReddy E-Manage hooked up to the car..i think i can go in and change fuel curves slightly with this system...im not sure but heres the info on that ....


GReddy’s e-Manage is a cost effective programmable engine management system that allows you to properly tune your factory engine control without having to change the entire factory ECU system to an expensive "stand-alone" unit or the inconvenience of sending it out for a full ECU reprogram. The e-Manage system is a true universal "piggy-back" type unit that taps into most Japanese factory ECU wiring, by utilizing the vehicle’s existing sensors (or optional upgraded sensors if factory sensors are maxed out). The major benefit is the factory ECU settings become your "Base-MAP" for tuning. There is no need for extensive tuning for normal driving conditions, but does allow the tuner to fine tune, adjust for injector changes, and add new MAP(s) for situations the factory ECU is not capable of (like on-boost conditions). And as technological breakthroughs are achieved, we offer FREE updates via our greddy.com website’s Tech page. Basic functions will allow the tuner to slightly alter factory injector duty-cycle (± 20% at 5 preset RPM points) by intercepting and altering airflow or MAP sensor signals. An option for Honda VTEC cars will allow you to even adjust the VTEC shift point. Additional features are built into the system but are only accessible through the use of the e0-1, PRofec e-01 programmer or our PC-Windows based "e-Manage Support Tool" communication software (sold separately). There is a 16x16 airflow adjustment map, a maximum 50% larger main injector correction adjustment, upgrade air flow meter adjustment, boost limiter cut, anti-engine stall, VTEC-fuel adjustment, real-time map trace, real-time display, real-time communication and basic Data-logging. With the use of our "Optional Injector Harness" and the software, the unit has the ability to control an additional 16x16 injector duty cycle map and the controls for adding up to 2 additional sub-injectors. If the "Optional Ignition Harness" and the software are used the unit has the ability to control a 16x16 ignition timing map. All of the above maps can also be map-traced in real-time as well. If the factory range of map or airflow meter is surpassed, you can incorporate a larger airflow meter or our "Optional GReddy Pressure Sensor and Pressure Harness" to set larger scales of adjustment. All installation and tuning should only be made by a trained technician with proper air/fuel monitoring tools. (Some or all functions may not be compatible with some applications.)
