    I was thinking the same Bobby. This is the part of this project we all knew would be difficult getting the motor through that subframe. So I'm following along to see what they come up with. With the frame that low I don't think you could even get the car to sit level without it dragging the ground so they definitely have a lot of custom work to do suspension wise. Looking at it from those pictures seems like it would have been easier to split the subframe into 2 separate pieces to keep the mounting points original and then make a tube frame crossmember or the like to reconnect them under the trans.

    Hey maybe he's gonna go 60's gasser style with it. Straight axle and all with that nose high stance. haha

    j/k. I'm really interested to see what your dad has planned. And really cool to see something completely off the wall and different in these cars so I commend you guys for that.

    I am definitely following your build. As an engineer, I always appreciate when people think outside the box and push the envelope. Really interested to see what you guys do with the front end though as I completely agree with Bobby. Keep the updates coming!

    We fabricated up some strut spacers today, anyone need a lift kit for a 2G 1995-1999 Eclipse? No one? OK, perfect.

    I do sound worried but my dad is an excellent engineer and fabricator. He keeps telling me, "Stop worrying, I have a plan"

    Thank you! Some people might not like the idea behind our build but we are trying to go a different direction than what others might think we should do and I'm ok with that.

    Currently got the engine dropped in temporary. We almost have the front suspension all complete. We are still waiting on some parts to come in the mail to finish up all that. Coming together for sure!

    If anyone knows me personally, it should be not surprise on the interior choice I chose for the LS Eclipse. I acquired some OEM 99 Eclipse black leather seats along with door panels and black seat belts. I'm trying to keep the OEM look with a little bit of muscle car flare to the car. After an hour or two of cleaning them up in my garage, they turned out pretty good! The drivers seat does need some attention with a tear on the bottom cushion but it shouldn't be to hard to get that fixed later.

    As for the rest of the car, we are still working on the steering rack and suspension but hopefully the car should be on the ground next weekend. I don't want to jump the gun on posting pictures until it's on the ground.

    Lots to post about today. Even though I am still waiting on parts to get the car on the ground, I wanted to share what we have been up to.

    First my dad fabricated a frame to house the steering rack and yes we moved the steering to the front of the car. Seems to be no other way around it and we were aware of that using the factory engine cradle modifying it.

    We started to clean the underneath of the car and previously we were going to use a rubberized undercoating of some sort but we decided against that since the body of the car literally has no rust so we wanted to show off the beauty of the car. The car won't be driven in winter months and will be taken care of pretty well.

    Also I decided to use 2G GSX rear end. We found a donor rear end even though it was rusty, most of the components will be changed out and we sandblasted the frame and it turned out amazing. Also instead of using the 4 mounting points for the rear subframe, my dad decided to use the factory FWD mounting point as well so now it will have 6 mounting points instead of 4. So he fabricated a bracket to weld to the frame. We are also using a LSD rear differential, just don't have it fully cleaned up yet.

    I tried to include everything thus far, it's a bunch to say but it's coming together! I will provide an update once the car is indeed on the ground. Just a few more things we are waiting on to show up.

    So you swapped the knuckles left to right to make it front steer. Definitely a good choice given the factory rack's location. What platform did you source the new rack from? I love the simplicity of the two bolt mounts. And hopefully it's a faster rack because the factory one is awful.

    I wonder if you will need to extend the parking brake cable slightly. Mine is already taught at the stock height.

    We got the transmission tunnel almost completed. Gas pedal and brake medals are currently being modified to accommodate it. Did some cleaning of the engine bay and front / rear wheel wells. Engine bay and wheel wells should be fully coated sometime next weekend.

    Also my brother-in-law found me a perfect LS1 intake manifold for the build. Believe it came off a C5 Corvette of some sort.

    We are also in the drawing stages of fabricating some one of a kind parts for the 2G that I guarantee you won't see on any other.

    you're going to send that factory 2G rear diff into next week, especially if you are only using the 3 factory mounting points.

    I am loving the ingenuity here. But ya I gotta agree with the above there's no way that factory 2G diff is going to hold up to V8 torque. Better start looking for a straight axle or BMW center section if you want to stay independent.

    Also waiting patiently to see this thing sitting on the tires. Still scratching my head trying to figure out how this car is not going to look like it has a 3-4" body lift with those spacers under the subframes and spring. Unless that is the look your going for?

    @babyviper, that is not the exact diff I am using. It was just the old one up there for mock-up purposes. The rear is not done yet. I'll post some updates when it is done. Just alot of back and fourth right now with waiting on things.

    @95REGF150, I do have new axles on the way and should be here in about a month. Already have a center section already here that is plan A. I don't think I am the best person to explain the whole setup, once the car is done, I'll try to do a video on the car with my dad explaining the whole story upon what is going on and why we chose to go this route. I'm not one to spoil all the fun but honestly I wouldn't know how to explain it perfectly without more questions being asked.

    We got the engine, engine bay, and wheel wells fully painted. The engine was painted in a silver satin finish where as it was previously a neon green color. The engine bay and wheel wells were coated with a bed liner like material and looks stunning. I am still pretty shocked how good it looks.
    The LS6 intake couldn't have worked out any better and looks great under the hood.

    Along with new hubs, rotors, brake pads, and axles have arrived.

    Currently we are picking up the new transmission tomorrow afternoon and should be in the car soon.

    As for getting the car on the ground soon, I am kind of in a dilemma on which wheels I want to use on the car. As soon as I make up my mind and what size wheel and tire we want to run, I'll order them and hopefully have something to show you guys.

    Good progress. Creative approach to adding the GSX rear subframe.

    It looks as though the engine is offset by an inch, or so, to the right. Is that to allow for clearance of the steering shaft past the headers?

    Sorry for the delayed update, I personally was not happy with the suspension and wheel setup. After about three different wheel setups and some tweaks later to the suspension, it's just about there. Here are the new wheels I am running on the car. Hope you like them. I wanted to go with something that kept the tuner aspect of the car while still giving the car a little bit of a muscle car edge.
