87 tin top AHU/1Z swap

samuraitd · Jul 12, 2015

Figured I'd start a new thread for my new build I'm starting. I picked this 87 tin top up from the auto auction. The plan is for an ahu or 1z, whichever I find first, with air conditioning, and power steering. For this build I'll be keeping the samurai transmission and transfercase, and will be staying electronic this time around. 30x9.5r15 tires, yj leafs spring under, and roll cage will also be in the works during this build. Look forward to getting into it and posting pix on here.

Looks like a really clean starting point. Look forward to seeing your progress.

Thanks. I'm not sure yet if I'll take on the wiring myself, or have fastforward do it. I don't know if I have enough knowledge to do it.

I would like to have cruise as well.

Still looking for a donor car. Collecting parts otherwise. Picked up a set of mk2 recaros for it today. They are surprisingly clean.

samuraitd · Aug 19, 2015

Did a little pre diesel prep tonight. Pulled the old 1.3 motor- or what was left of it. Still on the lookout for a donor swap. I found one local I'm thinking about buying but haven't popped the cash yet

The body on that looks superb! I'm picking up a new to me 87 ragtop this week. I would love to do this swap, will be following yours closely.

samuraitd · Aug 23, 2015

Thanks. It's really clean overall, but still has a few flaws. I've already done an mtdi swap on my other one, but I pulled it back apart to rework a few kinks I had with it and haven't fixed it yet.

I really like the CRs. The one in my 09 Jetta is just a great engine. I know that the Sammy transmission would be overmatched by it, but I'd love to run one. I definitely want to keep the original driveline, and want to minimize lift as well (prefer OME). Looking forward to seeing how you do this while retaining the Sammy trans and using SUA Jeep springs for lift.

samuraitd · Aug 24, 2015

I looked into the cr, but it's gonna be too much work for me. If I did it, I would probably swap to Toyota driveline to handle the power.

samuraitd · Sep 25, 2015

Bought my donor finally. Got to go pick it up yet

samuraitd · Oct 12, 2015

Picked up the donor yesterday finally. Runs, but intake manifold is extremely packed with crap. Planning on stripping this motor down and doing some stuff before I swap it into my zuki.

samuraitd · Oct 15, 2015

Motor is 50% pulled. Planning on pulling out entire subframe. I want to keep the motor and trans together so I can try to start it once I start stripping the harness and building my stand alone harness.

samuraitd · Jan 9, 2016

I think I accidentally threw away the maf when I cleaned shop. Anybody know if it's something I absolutely need? Can I run well without it?

samuraitd · Jan 9, 2016

Been trying to figure out the wiring. Motor has been pulled from donor. Just gotta figure out what goes where and try to connect everything correctly, and then start cutting.

It will run more like VW stock with a functioning MAF. The engine will start and run without, but most failed MAF are replaced with working ones for a reason.
M-TDI wouldn't need it, other tune levels might not require it, but I suspect a used MAF will be cheaper than a MAF delete tune.

algirdas · Jan 9, 2016

I may have a used MAF in storage.

samuraitd · Jan 9, 2016

Yeah I figured I'd be better off keeping it. I got the harness 75% stripped now. Just gotta figure out what several more thin wires go to. I'm pretty sure they are for the cluster, but not positive.

So, regarding the 109 relay, it's what closes and supplies power to the ecu correct? If I'm reading this wiring diagram correctly, I believe it to be so. And can I remove it, and run a generic 40 amp 12v relay switched on with my suzuki ignition? In my mind it makes sense, just wondering what you guys think.

samuraitd · Jan 9, 2016

Nevermind, I see now that pin 38 is from the ignition switch. I'm guessing that it goes through the ecu and then powers up the 109.

Alchemist · Jan 9, 2016

That power relay circuit is a bit of an odd thing. The ECU gets switched ignition on Pin 38 Black. This wakes it up and it then puts a ground on Pin 42 Black/Violet which activates the relay. You can use a generic relay if you connect terminals 30 and 85 together and 86 to the Black/Violet wire from ECU Pin 42. Terminal 87 then goes to ECU Pins 23, 45 and 68.

samuraitd · Jan 9, 2016

Coolio. Which pin is for ground also?

samuraitd · Jan 10, 2016

I think I got the wiring all figured out finally. This engine is now going into my other convertible instead of the tin top sami.

1.9ZOOK · Jan 10, 2016

Ah,like myself, a Man of many Samurais.
I always say "You can't have too many of `em.

samuraitd · Jan 10, 2016

I had 6 before I turned 18

they are my favorite vehicle ever, second favorite is my diesel vw's, so I mix them! I'm 21 now, and still have my first Zuk, it's got an AHU mtdi now though

samuraitd · Jan 11, 2016

Acme adapter kit ordered. Working tonight on getting the pedal assembly mounted.

samuraitd · Jan 11, 2016

1.9ZOOK · Jan 11, 2016

That came out nice,same plane as the other pedals.

Didn't if though? It's surprising to me how similar it came out compared to the Sami pedal. I cut the bracket up, and had it installed 15 minutes later. Super easy stuff.
