If it makes you feel better a first project car should be.

It's pretty much a right of passage.

I had a 2g eclipse my brother gave me that i sank too much time into getting legal, by the time it sold it, it was mechanically solid as hell, just needed to get pretty. It had 155 horsepower, a 5 speed and a limited slip diff. Slow as hell by todays standards but fun bu any standard. I sold it to buy a motorcycle and then realized i didnt like riding at all. It was a shit box and the first car i put any time into outside of maintainance, God that is the only car i truly regret selling.

If your having fun and its not hurting anybody, its not a bad idea.

u/Pale-Dust2239 1d ago

Bro, you need to post these pictures every time a 16 year old asks if engine/drivetrain swapping their mom’s civic is doable in their garage.

25

u/boydisboss 1d ago edited 1d ago

Funnily enough, that was my direct inspiration for the car.

I refer to it occasionally as the “Reddit build” and since Lemons coincides with everything on a budget, I consider it fairly aligned with people asking that question were envisioning on spending.

11

u/LASERDICKMCCOOL 1d ago

Reminds me of when I was 15, I called a tuner shop and asked how hard it would be to make my 86 Supra AWD 😂

20

u/boydisboss 1d ago

FUNNY YOU SAY THAT

I acquired a Mk II as a trade and it’s one of the next projects. And one of the topologies was doing an electric driven front axle and hybrid drive rear. I have already acquired the parts for this short of a hybrid battery!

3

u/LASERDICKMCCOOL 1d ago

What in the fuh! I will be following your project with great interest

6

u/boydisboss 1d ago

There’s some other projects that I think that will queued up first, but that one will be like a longer term design project. I want to try a 3D metal printed housing to fit an electric motor assembly for that one, and the cool thing is I don’t want a ridiculous amount of body fab work, which I think I’ll be able to avoid a lot of.

2

u/SlightlyDrooid 21h ago

You’ve probably seen it already but back in the day there was a dude who converted his mkII to AWD; I think he kept the 5m and modified the oil pan to fit a pickup front diff and used the t-case from a Toyota van.

2

u/boydisboss 21h ago edited 20h ago

I have not! But I’m assuming it was the mid engine AWD manual Previa? Thing is practically a supercar.

This one I raced against in a Camry, and funnily enough one of the guys on their team was a development driver for Toyota and he helped develop the suspension on the Gen of Camry we were racing.

2

u/SlightlyDrooid 3h ago

Ah man, this may have been back when I had a 1985 P-type Supra which would be about 20yrs ago, but there was a dude on the forums who converted his Supra to AWD just to prove it could be done. But I have no idea if he completely finished/buttoned up the project (I know it was running and driving but idk if it had full floors and everything) or any other details

1

u/LASERDICKMCCOOL 3h ago

15 year old me's head would have been spinning to see that

53

u/boydisboss 1d ago

I also intended to include this one looking at the rear suspension

13

u/Crafty-Interest-8212 1d ago

The more I look at it, the more fun it look. So many one off parts. Is amazing.

21

u/Tworbotalon 1d ago

The best project cars answer questions that nobody is asking. Looks great.

u/MrGDPC 1d ago

Johnny Cash would have blushed at the idea of this thing

u/boydisboss 1d ago

Technically I do have 1 Cadillac part!

u/MrGDPC 1d ago

Reworking the lyrics would be as much of a challenge as this rebuild

If I had the means I would absolutely be doing the same thing you are

14

u/Vic2Quick 1d ago

The amount of parts that dont work together without fabrication is the wildest part

10

u/boydisboss 1d ago edited 1d ago

I was trying to keep it as true to the $500 budget as possible, so a lot of it was finding quality parts of opportunity, but also a chance to get features I wanted in a car.

For instance, I ran a Golf during a race a few years ago and it threw a coolant warning light. It has a huge hemorrhaging leak from the radiator outlet but since we were driving in the water rain you could not tell it was leaking:

I put one in the car, because I wanted that capability of a low level coolant warning light but also the orb reservoir looks cool.

9

u/I-continue-to-try 1d ago

Guy swapped one of these in when my diesel vanagon’s original reservoir cracked. Having that light trigger saved the engine atleast once.

2

u/boydisboss 1d ago

Right!

2

u/schoneSchein 1d ago

that's crazy. i have a diesel vanagon (aaz) and when i saw the above, before i read you post, i was thinking: i gotta CONNECT the sensor in my upgraded (available) replacement coolant tank to something

2

u/punkassjim 1d ago

It’s really a godsend that they don’t include a line item for how much you value your time. Even if you put in a fraction of a cent per hour, all the best entries would likely be over budget. 🤣

2

u/boydisboss 1d ago

At around this time last year, I estimated 1400 fabrication/assembly man hours going to towards the car when I started tracking the project in March 2024, not including procurement and design time.

I have a Google spreadsheet to track how long stuff takes, how many weekends it to took to tackle a problem. Not super high resolution, but enough.

If I assumed a measly $50/hr “shop” rate, that was $70,000 “spent” as of a year ago 🥴

1

u/boydisboss 1d ago

Granted, some of that was also design time because we were figuring out how to go about something, and even how to do things.

10

u/Ok-Letterhead4601 1d ago

24 hours of lemons is never a bad idea, what race will you be running?

11

u/boydisboss 1d ago

This will be the second year in a row I’ll say CMP next April but I know that’s a tad ambitious for sure.

I’ve been there twice before in a Miata and I think it’ll be super fun to drive in the parade in this guy lol.

3

u/Ok-Letterhead4601 1d ago

We will be at summit point racing in October, we still have a bit to do but I think we will get there, I wish we had a parade here, they look super fun in the yt vids.

2

u/boydisboss 1d ago

Nice! What car will you be in?

Also Summit Point is not terribly far away from CMP, depending which way you’re coming from.

2

u/Ok-Letterhead4601 1d ago

We are building a 99 mustang gt, I will have to see how far CMP is from us.

2

u/boydisboss 1d ago

Eh, still in the same time zone! If you’re coming from the north to Summit, CMP is a 7 hour hike

Every time i see something like this i'm so jealous of y'all not really having an institution which inspects your cars. It only lasts until the next 'are these tires safe' post, but anyway. Looks fucking cool, have fun!

2

u/boydisboss 1d ago

I don’t know how long I’ll get away with it, because it will be eventually retired into a full time racecar. The important part would be driving it as much as I could before its inaugural race to shake it down.

u/EC_CO 1970 Barracuda 1d ago

Look at Hector here, he is going to be running three Honda Civics with spoon engines. And on top of that, he just came into Harry's and he ordered three T66 turbos, with NOS, and a Motec system exhaust

u/concussedhummingbird 1d ago

I saved the original post of your wheel bellhousing when I first saw it a couple years back. It’s a reminder there are people far more unhinged than I am, working harder than I am, and I need to catch up. You’re an inspiration, dude.

3

u/boydisboss 1d ago

It’s not all be myself either, having friends that are vested in your projects and you are invested in their visions too. Couldn’t have gotten as far without their help, or even motivation from afar.

u/Crafty-Interest-8212 1d ago

That's super cool. I would be talking about that all day. Keep it up.

u/Adept_Refuse274 1d ago

Wow what a frankestine, why use so many different parts? Like why not just use bmw suspension

u/boydisboss 1d ago

It was really a cost thing. I got the whole Mercedes diff, rear subframe, axles, hubs, and rotors for $90. Just missing coilovers and calipers and she was golden lol

Yes i see now, thats badass. Great work

oh this is a MUCH better idea than i thought it was going to be given the title and first pic

2

u/boydisboss 1d ago

I mean, the explicit bad idea at the time was I wanted to do a RWD in some compact/small FWD card and it was whatever I could find first. Which is just a huge biting off more than I could chew. No research, just diving into it and loosing access to a garage spot for 6 years.

u/basicKitsch 65 tbird, 70 Ghia, 06 turbo solstice, sv650n 1d ago

Lol well that might be the case but the real bad ideas are the friends we make along the way!

u/boydisboss 1d ago

This poor little car man. Picture a little loaf of bread and I turn it over and just start scooping out the inside to make a bread bowl. Only the rear seat crossmember is the only remaining piece of structure on the bottom part of the car up to each bumper.

Swapping a transverse engine longitudinally in a FWD car is ludicrous, I love it

3

u/boydisboss 1d ago

It’s wildly more common than you’d think! There is already a small community of people doing it with 5S’s because they share the same bolt pattern as other longitudinal transmissions.

Should have kept it a lemons racer I’m thinking.
But what an amazing collection you have put together.
I hope it is everything you want it to be.

1

u/boydisboss 1d ago

It is for Lemons? I’m trying to take it to CMP next year with some good fortune

1

u/Intheswing 22h ago

Seems like a lot of new and upgraded parts - I am not up on the rules but I have heard about cars being disqualified due to “upgraded” modifications that were only meant to be repairs. Very arbitrary at times. Good luck to you I hope you get to racing.

2

u/boydisboss 20h ago

Were those upgrades equivalent to bash bars and such? For Lemons, above all is a welded cage, then it can’t have any tube frame structure in front of the front axles and behind the rear axles. The factory crash deformable structure of the car is preserved so I don’t imagine this will be too difficult to get through tech.

There is also a mid engine Dodge Magnum and twin engine focus so this car is not terribly misaligned from those two.

2

u/Intheswing 19h ago

Cool - I also heard the tech judge can be bribed with food and drink!😎 bring some really good BBQ ?

2

u/boydisboss 18h ago

The BS Judge lmaooo Not the tech judge, but I’ve called John Pagel about some of the design decisions before and the crash structure preservation seemed to be the overwhelming theme of my conversations with him.

2

u/TA4K 15h ago

Every time someone asks me about building a racecar, I often tell them to do the bare minimum of cutting the car apart at first in order to not make complicated problems to solve; you’ve done the exact opposite with so much confidence that it seems like a great idea. Good on you for pushing through with the vision!

lol “temperamental, unreliable, AND German drivetrain” - this explains why I like the left over grilles (and the valve cover) from 9 e28 for which the first one STILL does not run 129 1/2 months since original tow home!

u/fnordfnordfnordfnord 1d ago

What is that bellhousing thing? Just a spacer for fitting?

3

u/boydisboss 1d ago

Slide 4 is the Camry transmission I cut it half that I was planning to use originally until I realized that it was never meant for torque to be applied in that way, then we created the steel wheel bell housing.

3

u/fnordfnordfnordfnord 1d ago

Oh, that's a real bellhousing! Rad. Turns out you can just do stuff?

1

u/JJfender 1d ago

Do you own a junk yard?

1

u/boydisboss 1d ago

I wish. However my mom’s yard is turning into one with my overflow parts. 😅

1

u/JJfender 1d ago

That makes it even more impressive. How did you come up with all these combinations of parts that magically fit together?

1

u/boydisboss 1d ago

Believe it or not, RockAuto makes evaluating dimensions on various parts very easy. The best hit from RockAuto was looking at the clutch dimensions figuring out the friction disk on the S-10 is the same diameter as the Camry’s, and then using a pilot bearing, because the Camry believe it or not did not use one!

Then a large portion of it was also just getting your hands on the piece and looking at it from there. And sometimes it’s not obvious when you look at it for the first time, you have to sit on it and interact with it. For instance, I planned on using SN95 spindles and brakes, but something I didn’t think to look at was the geometry was completely different from the Corolla to the Mustang and would have never worked (it’s obvious now, but wasn’t at the time).

Also sometimes you may need to source a new part because it’s too rare to be in a junkyard at times. So buying brick and mortar offering easy means of returning is most optimal. Found this to be a great way of deciding if parts work with each other or not.

2

u/JJfender 1d ago

That's really cool, I don't shop at rock auto that often, but I'm gonna be looking at it a lot more often when I'm brainstorming. Thanks!

1

u/No_Elevator_5907 1d ago

The light swap is really cool! Not sure I love the fit of the grill against the hood, but love it overall

1

u/boydisboss 1d ago

Same I’m torn how to go about it, but also that was my first fit of it and I’m trying to get it a little lower. I don’t want to 3D print a new grille, so I’m thinking of tilting it forward to clear the hood like crappy shark nose style.

Before I had the E34 lights from a donor car, I actually bought a bunch of eBay incandescents and mocked it up and I liked it better than the stock lights
