'94 Civic Sedan Build (previously turbo... now a D15Z1 VX OEM rebuild/swap)

[94EGCoopey]

Got the ecu, manifold, and egr stuff today! Thanks Tom!

Picked up my 4th HX wheel. Stripping it down outside now. Hopefully have it mounted tomorrow so I can put the rears on this weekend as well as the rear ARPs.

Hopefully getting the A/C **** tomorrow as well as new doors so I can be dent free!




A/C is 99% installed. Installed a new expansion valve and mounted the evaporator. Installed all the lines, condenser, dryer, mount, a/c compressor.

Just have to tighten the two large connectors, remove the "dead" button, and then charge the system.

Oh, and I forgot, I need to rewire the evaporator temp sensor. My car is a 93, so its wired for R12. The a/c system is R134, difference being is 2 Pin for R12 and 3 Pin for R134. No biggie though, I got the pigtail today too!

Got the rings in. Here is how it will sit for the night:









Practicing my steadiness. I suck.

Well, after some bead blasting, the block didnt come as clean as I wanted, nor did the head. So with alittle help, they did.

Just waiting on my oil pump to come in. Then my Water pump and I can put the rest of it together.

*The painted over studs will be replaced. No I didnt slack lol.*

aside from the valve cover(Which you should paint), that engine looks brand new. I was amazed when I saw how much you cleaned it up.

VX motor in a lowered sedan - nice. Like the wheels.

Did you copy this thread from somewhere else?? You got a heck of a lot done between 3:31 & 3:38 AM E.S.T.

PS - hope you don't mind I added the D15Z1/VX info to the thread title. Will attract more eyeballs here.

I started a new thread before I saw your build, oops!

I'm getting a '95 EX sedan for a 'VX Sedan' build project. I will be using HX wheels, too. I'm considering making a hybrid transmission using some combination of EX/DX/Si 1-4 gears to 'help' with city acceleration. My major desire for this project is to be a highway machine benefiting from the lean-burn engine as well as the VX 5th gear.

I also am going to make this a much improved handler for the twisty stuff, so looking forward to that.

What kind of highway mpg are you expecting (say at 65mph or less)?

Looking forward to more pics!

Thank you. I paid $120 off craigslist with brand new tires. They are Rota Slips.

For now they will remain on. Any distance traveling I will put back on the HX wheels as they are lighter.

Thanks! I am really anal about things. If I clean one thing too much, I have to have everything match. So the intake manifold is getting bead blasted as well, the dizzy will be painted, egr will be scrubbed, alternator and starter will be new just so they look right.

And the valve cover is on just for the fact that I didnt want to paint the head without a cover on and risk getting paint inside.

I built mine with the intentions of spirited driving. I love twisties and curves. I replaced all ball joints with Moog pieces, brand new wheel bearings, arp extended lug studs, and have some adjustable camber arms with new ball joints coming. Last thing I need to replace is tie rods.

I had to shave my calipers (they are GSR Calipers) to get them to clear the HX wheels up front.

I am aiming for 60-65mpg when I am done. I would really like to get my hands on a D15B (3 Stage Vtec) head and try my hand at a turbo setup.

I got some decent plans up my sleeve, just getting them to fall into place.

[379Kcivic]

Wow! That sounds amazing. I read about someone doing a turbo 3-stage vtec motor which yielded some amazing h.p. as well as 50+ (I believe) mpg!

I'm particularly looking forward to your work on the suspension, your skills are far beyond mine!

60-65 mpg sounds incredible.

I'm looking at a stock VX engine /trans swap, some minor aero mods and highway speed under 65...I'm just hopeful that 50+ mpg is doable with the stock Z1!!! (although the thought of total sleeper mode in a sedan that gets 60 mpg sounds awesome. But again, your skills are waaaaaay beyond mine. I might have to pony up some cash down the line.) Great work!.
