I finally have some time to get a thread together on my rebuild as the laguna is FINALLY at the body shop getting a thick coat of primer and not in my garage. I wanted to share this process as I have seen others do the same and got some good advice and feed back from the community.

As a junior in high school in 2002 I inherited this 75' Laguna S-3 400ci from my grandparents estate. Grandpa had bought it for Grandma new in 75 and she drove it for 25 years.



When I got it the 400 was sized due to a head gasket leaking coolant and sitting for 3 years. I had the motor rebuilt dropped it back in and had it painted on the cheap. 2001 Plymouth prowler orange. (yes I know the stripes are not right, the painter didn't understand what I wanted)



I drove it daily on and off for the next ten years through college and after when I was between other vehicles and bikes.

Just this spring I convinced myself after way too many Youtube videos it was time and I could cut out all the rust bubbling under the paint weld in new steel and get the paint job it deserved.























After a very long summer of sanding through 7-8 layers of paint and primer, teaching myself to weld and do filler work I had the outter wheel houses rebuilt from flat stock,new quarter skins on, the filler roughed out and ready for the first coat of PPG NCP-271.

This winter I will block out the panels and get it ready for color in the spring. Also will be replacing both front floor plans this winter. Same 2001 Plymouth Prowler orange with correct stripes will be going back on.

Plans going forward the next few years- 5.3 LS swap. looking for a LS1, L33 or LM7 with a 4L60E. Then rework the suspension once the new power plant is in and I can tune height and handling.

I will post more pics as it progresses. Thanks for reading.

Keep up the good work and keep those photos coming.

(I like your technique for removing the Laguna front end; those bad boys are heavy).

Looks like you're off to a great start Chad. You are going about it the right way.

My old co-worker has a '77 that had rusty quarters and I told him to do what you did and put on new skins and patch his wheel houses. He didn't. He just had the quarters patched. I told him they would break out with rust again in the spots that weren't fixed yet (that you couldn't see yet) in six months. I also tried to talk him into Laguna stripes since he put in a '74 Laguna nose. No dice on that either. He put on '70-'72 SS stripes that he had before that. He had it painted a beautiful silver (I'm not a fan of silver in general) and the stripes were black. Those stripes do not look good on that car in my opinion. Anyway, it took all of four months for the rust to show up on the quarters again.

He had it fixed again, but the same way, not replacing the quarters. This time he had it painted Corvette yellow, again with the black SS stripes. I only saw it right after it was painted and I haven't seen it in a long time, but I'm sure the quarters are rusting again. The yellow looked bad on it too.

Sometimes you just need an encouraging word from people who know what you are dealing with first hand. Thanks guys.

Change of plans, primer and paint is expensive but floor pans are cheap...and already paid for.

Shot with light under car to show the pinholes.









Question: If lap tightly, seam seal and under coat the heck out of it, will i get another 40 years out of these pans? The S-3's days of snow and rain are over. If not, I'll take the time and butt weld them.

I always prefer to butt weld, but if everything is seam sealed and under coated well, there's no reason they shouldn't hold up to the limited bad weather exposure they will see.

Thanks for the input Jay. I was on a roll butt welding the passenger and sure enough ran out of gas. Ill finish it up this week and start the driver side which i will lap. Butting it was not too difficult just time consuming and considering my small garage is unheated and no insulation its dang cold to be working with sheet metal for hours on end.

It was a long winter but I finally finished welding the floor pans. Seam sealed top them top and bottom, painted the entire pans and put down Rammat heat/sound deadener. (http://www.raamaudio.com/) The foil self adhesive you see in the pics is pretty good stuff. Sticks like crazy as long as the surface is clean and dry. I cleaned thoroughly and used wax and grease remover just to ensure I never had any lifting problems. It is pretty easy to work with and mold to the contours. I opted for their Ensolite peel and stick foam - not so cool. I have not installed yet but it is very cheap, thin foam pad. I have better stuff lining the drawers of my tool chest. At $40 / yard i'm going to use it but i'm not expecting much from it.

I am still working on body work. Turns out, it is not my specialty. In the mean time i have also been cleaning up the slope nose. After hand sanding through several layers on the easy to reach surfaces i decided to take a chance on sand blasting. I spoke with a local shop who said they have done the trans am snowflake wheels but never the rubber front ends. They took it slow being very careful on the edges as to not round them off and it turned out pretty good. Just low pressure, no rush and use used sand that is not as sharp as fresh sand. I feel kind of stupid for sanding on it so much when it was so easy and cheap to blast. $80 for one hour and it is ready for filler. Oh yeah, I also decided to shave the font bumper. The stainless trim with the rubber impact strip were pretty beat up but came off without too much effort. I plan on using a plastic flexible filler like SEM Problem Plastic to fill in the rough strip left beneath the old trim to shape it looking factory and have the strip wrap all the way around the front seamlessly. Here are a few pics.

I got the Laguna all wrapped up and put away until spring. But not before the first round of hi-build primer, guide coat and wet blocked to 320g. There are a few highs and lows to address but overall i'm pretty happy considering im making this up as i go. First thing in the spring is round 2 of hi-build, block again out to 500g and hopefully color.

well i'm right in the middle of cleaning up the LQ9 to put in the S-3. Stripped down the the short block, cleaning up the heads and i'll start putting it all back together this week. I pulled the old 400 2 bolt last weekend. so should be test fitting the block with the Dirty Dingo motor mounts, CTS-V oil pan the original TH350 for now with stock 2.56 gear. Got my harness set off for rework/reflash.

HOWEVER, today i bought slightly wrecked 1994 caprice classic so i could use the tank, sending unit and pump. vehicle only has 80k miles but the weird and worthless 4.3L v8. Bonus - found it has the posi and 3.23 gear and 4l60E trans. Not a bad score for $400 and the guy says its only been in one high speed chase! HAHA.(he actually said that). And it was the being chased, not doing the chasing.

For now i'm going to get the LQ9 in and going with the TH350 and stock rear. Over the next year i'll get the trans, rear end etc from the Caprice figured out and clean up and maybe be a next winter project.

Thanks guys. It was a big night. Got the TH350 mated to the LQ9 and set into place. It could not have gone smoother, especially considering i did it all with out help.







Summary of parts used -
CTS-V oil pan - fits great. i lopped off one of the oil bungs but later found i probably didnt even need to do that.

Houghes flexplate adapter - seems to work good. a little squirly getting it lined up but slid right into place.

Harness - LSX-Harness.com stand alone with obd2 port, reflash I have not received it back yet but should have it in a week or so. Came recommended by a few other members.

gas tank - bought a wrecked 1994 caprice, took the plastic tank, straps and heat shield. straps needed shortening and made some new hangers but fits nicely. Walbro 255 pump on caprice sender.

motor mounts- Dirty Dingo DD-3500c. Very impressed with these.

exhaust manifolds - i picked up some 2010 Camaro 6.2 manifolds and flexible flanges from another member. these are two bolt flanges, not three. Driver side has plenty of room but the passenger side contacts the rear lower control arm mount. it will fit with some grinding of the outer lip.

This is where i am so far. Now seems like a lot looking back over disassembly pictures trying piecing it back together.

Almost done hooking it up. Have some wiring left to do and figure out how to redesign the drive by wire pedal to fit. Hope to fire it up in a week or so.

Looking good there!

It seems to almost everyone but GM who realized that the 1977-96 Caprice, etc. was nothing more than a 1973-77 Chevelle underneath in almost all aspects.

Drive by wire? Some of the earlier LSx motors had traditional mechanical cables AKA the 'true drive by wire'. I'm thinking 2002 down and, I'm pretty sure a throttle body from one of them would fit your LSx.

Thanks guys, I'm down to the last few wires and couple things here and there including the gas pedal. I hope to turn the key this weekend.

In 2003 they went to DBW and i got everything with my dropout. I do know the drive by cable assembly will work but the research I did sounded like i would need either a different ECU from a DBC vehicle or at a minimum get the ECU i do have reprogrammed to a recognize a DBC throttle body and wire in a throttle position sensor to the harness. I figured for now it would be easier to keep the DBW and see how it goes.

Magno - PM sent. I'd like to see what you did. I measured the relation of the gas and brake pedal to each other in my dodge ram and was going to replicate that because i am used to it and it seems comfortable.

Well after some fiddling with temporary wiring and the computer i got it fired up last month. Man it sounds great with about 2 feet of open pipe off the exhaust manifolds.

I also got the DBW pedal assembly modified and bolted in. its not the cleanest looking install but i plan on changing out the whole assembly later anyway when i do the interior. For now it just cleaning up some of the wiring and plumbing and resume body work.

I have been a little pre-occupied the last couple years and the Laguna took a back seat. My daughter is now 3 and we just found out we have another due in September. So figured I better get this car together ASAP or I will likely never finish. I dropped it off at the paint shop for the final time last friday. When i get it back in about a month(hopefully) it will be very orange and ready for assembly.

[image][/image]

When I unloaded the Laguna at the shop it was a nice quiet side street and I realized I have never driven the car after I finished the LQ9 swap last summer. So I took the opportunity and got after it a little bit... WOW! Even a bone-stock LQ9 with 2.56 open rear gear, it is an animal compared to the old 400 sbc! When I hit about 50 and closed in on the stop sign I had that oh S*** moment when i couldn't remember if ever messed with the brakes...nope, safe.

It really lit a fire for me get it back together early spring so its ready as soon as the roads are clean. Especially since I have a 3.23 posi with disc conversion out of caprice ready to slide in. It should really wake up the low end.

Lots of paint decisions to make. The fun continues.
