Default z6 in 88 std need help!!!!

Ok I'm bout to have the shop do this swap for me inside me 88 std, but I won't to provide them with all the parts they need in order to have it done. Can anyone provide me with a check list of all the stuff I will need to make this swap basically a plug and play kinda thing.
What I have right now:
95 d16z6
91 Si tranny w/ clutch installed
mounts for particular year
95 ex vtec wiring harness
resistor box
obd0-obd1 conversion harness
new cat converter
axles

In process of getting:
p28
possibly dizzy if it cant be located

What else do i need if anything??

They don't need the axles.
They can use your old ones - actually HAVE to use your old ones.
Your hub splines are the same as the HF hubs you may have read about in other posts on this board.
Your STD axles will plug right into that Si tranny.

If you really want to switch axles and use Si/Dx/Lx type axles then you need to swap out the knuckles for the larger hub. You could also get a set of 90/91 Civic sedan EX OR DA Integra knuckles which would give you larger brakes up front. You might consider getting a 15/16" master cylinder (90/91 Civic EX) to compensate for the larger calipers.

You will not need a resitor box if you are going to use the injectors that come with the Z6.
You only need the resistor box if you use the OBD-0 injectors.
D16Z6 is OBD-1 and does not utilize a resistor box.

As far as mounts, I believe you will be using all your stock mounts.
The Z6 mounts definitely won't work.
Double check your stock mount part numbers against the ones from the 88~91 Si.
I believe they are the same, but I'm not 100% on it.


Other than that, everything looks alright to me.

They don't need the complete "95 ex vtec wiring harness", but I guess if you have it they can take what they need from it.

Also, I'm not sure how complete your Z6 is.
Make sure you have the 4 wire O2 sensor in the exhaust manifold.

my fault. i should have said they are si axles. and as far as needing the resistor box i didnt know that. and also the conversion harness which i got from ww.JKobdconversionharness.com (price matched @ 103 shipped for me hit him up if anyone needs one) said it has the 4 wire 02 sensor with it??
and its si mounts too.
will the obd0 wiring harness plug up to the z6??

Well as far as the mounts go yes you can use the Z6 mounts the only mount and bracket you HAVE to change is the driver side from the Z6 motor because the Z6 mount and bracket on the driver side will not line up.
So take off the mount and bracket from the driver side on the STD motor and put it on the Z6 driver side also you need to shave the timing belt cover a bit.

so can i run a a6 wiring harness wit the z6. or will there be a prob wit vtec. the mech that I am having do my swap for me said that i need to get a 88-91 si harness becuz it plugs right in with my wiring from the fire wall and all. but i dunno if that right becuz they z6 has vtec which the si doesnt. [b] Or if you guys won't to and no a lil bit more then he knows then you can give him a call at 619 563 1506 and let him know wassup. His name is T. he is doing the swap on a lil red 88 hatchback.

i have done this exact swap and i used half of the old harness and part of the z6 harness and ran wire thru the fire wall. also i keep the stock std axles and hubs and i haved no issues so far. the ecu was repined inside the car (no conversion harness) and i'm running a chipped p28. if you have any questions pm me.
