If it were me I would wait on the transfer case and drive line until your top end is buttoned up.

In the outside chance that anything doesnt clear up top and you need to shift things around it will be much easier. Same on the cross member. Just run up a bolt or two to keep things in line and shift the focus up top.

Have you verified the trans is in the same location as factory? If so you will be set on drive line.

good idea I may wait on that and just put the crossmember in. Luckily the motor mounts are slotted so the engine can move forward or back. I didn't measure but probably about an inch forward or back from dead center of the slot.

Motor trans t case all in bolted up in final location. Stopped by my buddy's place and was going to see how today goes and it went well it will stay for now. Going back after class to bolt on the intake manifold starter and ac compressor.

Motor mounts ended up working out my bumper and crossmember ended up not allowing the frame rail to flex at all so the motor mounts wouldn't fit after taking the bumper off and cutting the crossmember the frame moved further apart to allow it to mount. Kinda scary IMO. I will put the crossmember and bumper back on to minimize flex still can't believe that.

Woohoo! Glad it's all in. Trans/tcase mount fit in factory location. It was almost a tad too far back less then 1/8 of an inch but we got it mounted up I may modify my crossmember to get it perfect unfortunately the slotted motor mounts are maxed out and can't go more forward.

Intake mani will need some firewall clearancing

Sounds like everything is back on track and moving forward nicely . Keep up the good work Chris and we hope to see squeaky back on ( and off ) the road soon .

Once you work through a setback of any kind, it feels great and spurs new modivation into the project! Getting everything mounted up and lined up is a huge hurdle to cross!

Keep up the great work!

Which cross member did you cut? I've lost track of which ones you still have in there.

The trans cross member has slotted holes for a +/- 1/2" adjustment. If you are in that window call it good.

I'll explain more tonight...for now here we go. Not nearly as much firewall mods as we anticipated. Going to rent a fan clutch tool now to get rid of the envoy fan clutch and fan sits way too far out

Ok so today was a great day! Getting the motor, trans, t case in was tough at first, for some reason the motor mounts seem that it was too close together at the frame rail causing the bolts to not line up. That was where I had left off but going in with a fresh mind it dawned on me that when I had put on my bumper it seemed as if I had to actually bring my framerails in together a tad by ratchet strapping and eventually adding in a crossmember, It added a good amount of rigidity to the frame I guess because once I removed the bumper and crossmember it allowed the frame rails to spread enough to get the motor to drop right in to the mounts. BIZARRE! Either way with all the off roading and side winching I have done my frame rails may not be as straight as others but I do not have legit proof on that via a body shop. Its just an assumption. Either way I got the motor mounts in. It was a sigh of relief, so yes Current performance Motor mounts do work! then put my crossmember and bumper back on


The mounts are slotted so when it was time line up the trans/t case mount I could move it to make it line up. I had the motor as far forward as possible, they did fit but ideally the motor should have been up just ever so slightly to make it fit perfectly. My crossmember is not stock, when I did the SAS I made a new one to allow the use of longer control arms and when I built it it fit PERFECTLY with the OEM setup so I dont believe its the custom crossmember I made but the placement is ever so slightly off. Either way I can modify the crossmember a tad to move the mount back literally less then a 1/4 of an inch but like CaseyS said if its within a half of inch I should be fine.

After that it was time to get the flex plate bolted up to the torque converter and when I started to bolt the starter up I noticed 2 things, with the new oil pan and a bellhousing from an envoy there were 2 bolts that were longer to accomdate the other oil pan that sat much further down and the 2 bolts interfered with the oil filter and the other starter. Simple fix though, get the same bolts but a half an inch shorter. I think the starter one, because its connected to the block it should have a shorter bolt but I couldnt find it, either way a shorter bolt will do it.





The big question was the intake manifold. The rest of the swap has gone in without major firewall modification but I heard the intake manifold would be the worst. I spent no more then 5 min hammering the pinch seam back and the intake manifold fit. This was awesome! For years when we had heard that the H3 alpha had firewall modifications I thought they were major but in reality its nothing crazy.





The A/C compressor was also reinstalled, I had to take it out because it was in the way of installing the frame motor mount bolt from earlier so I put that back on. I also put away the coolant tank and windshield washer tank too.

I took the envoy fan and fan clutch off as they stick out very far. I am going to get an alpha fan and clutch, they will sit closer to the block and will hopefully fit with the OEM radiator where as the envoy one would not.

no more fan for now



I also had to cap off the vaccum line for the brake booster, H3s dont need it so it was capped off.

old line and the new cap



Tomorrow is my longest day of the week and wont get to work on much but thursday I would like to get the A/C condenser, radiator, and intake box installed. Zach has my MAF sensor, o2 sensors and rad hoses on order so they should be here soon. Harness is here soon also. I also can reuse my return line for the PS lines so I will hook that up but I need to go get a new pressure line made for the power steering. These lines are MUCH shorter then the lines for the I5 on a SAS. The box and the pump are literally right next to each other where with the I5 they are on opposite sides of the truck.

I still need to figure out fuel lines, A/C lines will be custom made, I could order the H3 alpha ones but for the price I can probably have them made cheaper.

Its slowly getting there

This is Awesome!! Can't wait for the final result.

From your experience so far, what issues do you think we wont face if swapping the V8 on an 09 i5 instead?

Today will be slow...work from 7-12 class from 1230-720. Tomorrow will pick back up. It's a shorter day.

For an 09 I5 to v8 you won't need to deal with finding and swapping a trans that has a input speed sensor, you should already have one. You shouldn't need to hit the firewall at all. Other then that I'm pretty sure it's about the same. Electronics may be easier depending on the year of your new motor but if you don't make your own harness that shouldn't matter to you, just to the guy building your harness.
