OMG.

can't wait until one comes up near me...

Thanks for the info on the swap...I will probably not get the chance to do that like you did but i'll keep my eye out for a blown-engine 'mechanics special' haha.

550 Miles is nothing. Just over a tank of fuel. Could be a fun day IF the car was as clean as envisioned.


The supposed VX transmission I picked up the other day is NOT a VX trans. It's got Si gearing At least I thought to check it BEFORE installing it. I personally saw the VX engine it was attached to when I was there picking it up. Oh well.

All is not lost though, the trans I ended up with is the closest gearing, lowest final drive ratio they made. Should be a good one for my future turbo D-series build.

The bright side is, I looked at our local pick a part online *two locations* and searched 92-95 civic. There was ONE CX there. I figured the drivetrain would be gone or swapped out but said to heck with it, packed up tools and drove out there this am.

I anxiously head to the car. Before I even get close to it I can see the drivetrain is gone.

I go up to inspect the car and see if the trans is laying in the hatch or seat or something but nope, it's all long gone..........

Until I look on the seat of the car NEXT to it. Boom, there a d series trans sitting right there.....could it be?

I anxiously stick it in 4th, mark the differential and input shaft.

One, two, two and 3/4 revolutions of the inputshaft made one revolution of the differential! YES! And I didn't even have to pull the damned thing!

Grab input shaft and firmly wiggle it around, it's TIGHT!

Get home with it, pressure wash the he!! out of it, boy was it greasy.

Yank out the DX trans, slap in the VX trans.

All went nice. Fire up the car ***WHIRRRRRRRRRR***

Crap I know that sound. Main shaft and or input shaft bearing noise. UGN......

Drove it around, yep it's noisy. Ordered a bearing kit to fix this seemingly hard to find trans which I will do next weekend.

At least they're damned easy to pull out and fairly simple to split open.


I can tell already the super high final drive is going to get me great economy.

Cruising at 60mph my gauge, on flat steady ground sits low 60's easy. Before in the same situation I was VERY lucky to see 50 in lean burn or not.

I was showing low 60's and NO leanburn yet as my RPM's were too low!

I like the taller gearing, the Y5 I think is a good match with all the VERY low end torque it produces *relatively speaking*

I can say with 100% confidence that gearing trumps leanburn for economy on the D16y5 no matter what.
