1HD-FTE Conversion - Creating my perfect 80 Series (2 Viewers)

[MooseMichaels]

@Mag71k5 Thanks - I had a family member who owns a local auto shop swing by for a competent second set of hands / eyes. We managed to get it in in around 3 hours, I'd guess, with a good bit of hanging out and chatting along the way also. Had it in/out of the engine bay twice to adjust how we had the engine hanging in the hoist to get everything lined up.

For anyone else trying this in the future - I ended up installing the transmission mount backwards (it's offset for the A750F) and ended up needing to rotate it 180 degrees so the ears point towards the back of the vehicle to get the front motor mount studs to line up in the slots.

We mounted the trans to the cross member, then did some massaging to get the front engine mounts in. The back of the valve cover was pretty tight against the firewall, but just needed to be patient get everything aligned.

I started mocking up the exhaust last night. I think I need to get an HDJ80 specific exhaust hanger for the section of the exhaust that has the flex pipe, because hanger on the frame for the 1FZ won't work. Also might need a lift to get the center section in, I have been struggling with it on my garage floor.

Very cool! Dream swap for my 91 3fe.

The airbox is fitted with the HDJ80 cap, and an OE 100 series rubber hose to the compressor inlet. I trimmed the threaded stud by an inch or so and cut some new threads onto it. Cut the feet off, modified them and tacked them back on with everything installed in place in the engine bay. It’s primed and ready for paint now. Should look clean with some fresh paint.

I’m liking the fitment of the PPD system out back. Looks beef.

Looks great! Have any pictures of how you modified the feet?

I’ll have to take some photos and post them. I used a spot weld cutting too to remove them, and did something very close to what lelandEOD did. One I shortened, and the swapped the positions of the two closest to the passenger fender. My goal was to get the soft connection between the airbox cap and the compressor inlet as straight as possible.

Not the prettiest welds I’ve ever done, but it’s sturdy. I was worried about burning through the thin wall of the airbox. A grinder and paint makes a bad welder great they say.

@Mag71k5 air box photos as promised. Question for you - did you connect this large barb on the vacuum pump to the vacuum connection for the brake booster?

Lastly, intercooler is here and is looking fancy.

uestion for you - did you connect this large barb on the vacuum pump to the vacuum connection for the brake booster?

Correct, just standard 3/8th inch rubber hose.

Awesome, thank you! Finally starting to put this rig back together. Jonathan said he’ll be shipping my harness and ecu out sometime next week.

Thats a huge step towards completion as well. Be sure and post lots of pictures! Did you have any issues getting the auto transmission in?

@Mag71k5 The auto trans went in while bolted up to the engine with the transfer case bolted on hanging wayyy off the backside. It was a long setup, but went in just fine. Needed a second person to pull/push on the transfer case to adjust the angle of the whole setup.

Yesterday I re-installed the 1FZ radiator, zip tied the 1HD radiator shroud place to see what was needed to make them work together. I was dreaming up a plan to draw up some adaptor brackets in fusion 360 and then have them made with send cut send. I realized I’d have more peace of mind long term, just putting in the correct HDJ80 radiator and not slapping in some adapter brackets.

I called my local dealer and they will have it for me in 3 days. 16400-17020

I’ll be selling the 1FZ radiator, it’s nearly brand new, from the dealer last year, no more than 10k miles on it.

I started mocking up the intercooler, trans cooler, and piping. A hood support bracket that also supports the bottom on the IC that is supposed to be part of the kit wasn’t packed into my kit, so I have a note out to their customer support to get one shipped to me a soon as they can.

For the piping on the compressor side of the turbo (headed to the IC), I am thinking I won’t use this section and will just keep the factory piping. I mocked it up, and it’s fairly tight in there. Anyone have experience with this?

Edit - after tinkering around with fitment going to use the factory piping for the compressor outlet side.
