Well I cant wait any longer for you guys. 23.5 years is a bit long to make a guy hang on. So I just went ahead and got it myself.

Good day, I have been a W body enthusiast since high school 04. In my student parking lot, we had a 93 Gran prix, 94 olds cutlass supreme, 94 cavalier z24, 95 monte, and my lumina z34. These cars were everywhere! My first car was a 94 lumina z34 (still have it). In 2012 I put a 4.9 PFI in it and it is almost complete. I just need to replace the rear suspension and odds and ends. I have a 99 Monte (needs some work), and I just picked up a decent (needs some work) Cutlass supreme. I am buying a new top for the cutlass on Friday. I want to get black canvass instead of the white (the car has black leather interior). They come in black, grey, white, red. What do you all think would be the best color? Just curious. Very few of these ole buggies still around (at least in my area). I thought I would join the forum to see what you all are up to (I feel very late to the party). I already have seen some super nice examples of these cars (nice job everyone!). Ill post more as spring hits and I can get them out, and work on them more. Also, not adverse to loading them up on the trailer for any meets that might happen. Thank you! Hope you all have a wonderful day!

Welcome! I think black top will look great on it. Better late than never! Not as bustling as it was back in the day, but there's a few of us W-body old timers left. I wouldn't mind seeing pics of the 4.9L in a W-body.

anyways, welcome to the site.

Hey everyone, My name’s Ryan, I’m from Long Island, NY, and I’m new to the Monte Carlo platform. I recently picked up a 2003 Monte Carlo SS and I’m excited to finally start a build thread and be part of the community. By trade I’m a licensed marine engineer, so I’m very hands-on mechanically and enjoy learning the technical side of things. On the automotive side, I’ve worked on and tuned a variety of platforms, everything from basic bolt-ons and wiring to full tuning using HP Tuners, Hondata, and standalone setups. I enjoy both the mechanical and tuning sides of builds and documenting the process. For the Monte, the plan is to start simple, catch up on maintenance, fix worn components, and do some basic bolt-ons while I sort out the body and cosmetics. Once the chassis and body are in better shape, the goal is to turn things up. I’m currently torn between a Gen V M90 top swap or going turbo, but either way the end goal is a "reliable", fun street car that still rips when you get into it. I’ll be sharing progress, asking questions, and learning as I go. Looking forward to seeing everyone’s builds and being part of the community.

Hi, I’ve just stumbled onto this forum, and i figure I’ll probably need to post here eventually acquired my luminator last year, 2nd owner from a grandma. 70000 (got w 55000)miles. Here’s some pics; thx yall

UPDATE: the car is going to the mechanic on 2/23 for this job. It will be going to a chevy dealer whose mechanic has decades of experience which is exactly what I was looking for. This mechanic is semi-retired and picks & chooses the jobs he wants to do. When he learned I'm the original and 4th owner he took the job. I was asked to supply all the parts which I think I will need. Included with these parts will be a new EGR valve and a new Low Coolant Sensor (due to the coolant being partially drained). I made a copy of Gnat's photo so thanks again for this. I will be seeing how the mechanic feels about just going the RTV route in lieu of pulling the rear head. Not only will the job be alot cheaper, I'd really prefer not opening that Pandora's box of potential additional issues if the head needs to be taken off.

Thanks all for this. As of the moment the car is in storage do it will be a while before I can check it out, but I will say I get more & more confident this will be the cause. It has been happening for a long time. Form the day I bought this car in Oct., 1994, I always wondered where a quart of oil was going every 1000 miles or so. My money is on this as pictured above, it was probably badly sealed to begin with. And these things don't get better, only worse. I went in and checked my 2020 repair bills from when I had the intake manifold gaskets replaced. The mechanic also replaced the gasket for the part 10130955 as you see in the photo but no mention is made on whether the distributor plug seal was addressed so I am going to assume it was not. While it's a shame all that work that was done to the motor back then would have to be re-done just to get at what needs to be repaired, so be it. Even if I decide to get the rear head pulled to replace the O-ring rather than trying my luck with sealant, that's still way better than having the entire motor pulled. I might as well go the whole 9 yards and have both head gaskets replaced for a one and done job. I should be getting the car out of storage within the next few weeks, I'll keep all posted on how things progress, and thanks again, much appreciated!

You're in the right place because we love our W-bodies here. Welcome!

Wow, that's awesome!

Got the fuel line disconnected and fuel can ready to go but no go on the fuel pump. Do I have it wrong here? The car has been sitting for 6 weeks so the battery may be weak but radio turns on. Edit nevermind I'm an idiot i see the number on bottom of relay and i had it wrong Works like a charm thanks all

Damn, that's a rare one!

I wanna see pictures of the Gran Prix, never seen one before! /s Welcome!

Does the pump run? If it does, unhook a fuel line under the hood and jump the fuel pump relay.

The thought here was that you don't drive your W's in the winter.

Unfortunately its the opposite of that pre-conceived notion of the south, they spread that stuff anytime the temp gets close to 32F overnight and its wet out. Ive researched a bit more into the options available and will go with the coated PowerStop kit from RA. Just trying to generate some conversation I guess...

A maroon or dark green GS, tan interior and tinted windows with "Buick" mud flaps hits a 99-04ish nostalgia spot. Would still have to have those logo puddle lights though.

My grandparents had a 04 Regal GS with a "supercharged" emblem on the trunk lid. If I recall it was on the driver side.

Check Amazon. Just search Buick logo door light. Some are stick on with double sided tape and a magnet style sensor to activate them one the door opens.

Welcome!

I was able to replace the o-ring and add an extra gasket with the information from the old double gasket thread all without removing the rear head. I also put RTV on it and it never leaked in the 10+ years I owned the car after the repair.

One should have the service manual within reach for electrical diagnosis.

This is the only device that will separate the fuel line from the rail.... there is another method you might try.... raise the car up high enough to get under comfortably & disconnect the fuel filter from the fuel line (one end of the filter makes used of threaded connection , the other end is the same ac/fuel line quick disconnect slip-on connection). Once again run a length of hose long enough to clear the car & fill a gas container to drain the tank.

there should be a loose red wire near the relay jump that to the positive post and it should turn the fuel pump on

spammer?

not even a difference ABS/non abs on the gen1 front knuckles. the sensor is separate of the wheel hub - why gm couldn't have continued this into the later cars is beyond me. buy whichever brand you determine to be the highest quality or fits within your budget

Welcome to the forum. That should be a good reliable car!

I guess I've been here long enough to say this, why are we bumping 15 year old threads? I didn't even read the comment, but it sounds like it's a bot that is advertising.

One thing to be careful of there is that 2004 was a bit of a transitional year. A 2004 Lacrosse is a 3rd gen W and came with the 3800 series 3, while the 2004 Monte/Impala was still a 2nd gen and came with the 3800 series 2. Compatibility wise, you’re very much going to be stuck running a compressor compatible with a 2004 Monte SS if you want any hope of things functioning properly. The other potential gotcha is that 2nd gens also ran a BCM. There is a possibility that the PCM requires input from the BCM in order for the AC compressor to run correctly in the first place.

Putting all of the *hardware compatibility* aside for a moment.... what ECM/PCM are you using to drive that L67? Are you using the 1227727 case or the 1614936 case?.........with a burned chip tune for an eeprom These are OBD1.. or are you using an OBD2 pcm?

I'm going to differ with you on this Kyle....... what OP needs is the necessary A/C piping from a 1st Gen Regal with the 3.8 engine. If you intend on keeping as much as your car is currently fitted with you'll need the a/c compressor manifold hose assembly that was fitted to the 3.8 Regal & a new rebuilt pre 94 compressor. Everything prior to 94 is R12 based, everything post 93 is R134 based. When GM introduced 134 in 94 they changed ALL of the A/C line fittings thread pitch so NOTHING from prior & post can be used together. My suggestion to you is to keep your 92 car all 92, get that old 92 3.8 manifold hose assembly & purchase a new *rebuilt* pre 94 A/C compressor, even the manifold hose assembly changed in 94 because GM redesigned the back end of the compressor housing for 94 so the old manifold hose will not attach to the newer design compressor housing. Purchase yourself a new receiver/dryer as well as a new orifice tube. Go into Rockauto, search 92 Regal, they still house most of what you'll need.

What they liked the best: The brakes. What folks complain about the most on this site: The brakes. I've said it before, I'll say it again: The biggest problem with Gen 1 brakes is not the brakes per se, it's the brake booster.

"Automatic shoulder belts"

I think youd have to do it by generation, as there are some significant changes by generation as well as intent (when you get to the later years there was more of a focus on handling handling vs the earlier focus on comfort handling). In addition, its important to consider that skidpad Gs do not equal handling. Ive driven race cars that would do an epic skidpad number but are so ill handling in transition/under braking/whatever, that they are virtually undriveable. I have the most experience with 1st gen w-bodies, and my vote there would be for the FE3 level Grand Prix coupe with the 245 wide tires. Though I suspect/wonder if the 1990 olds international with FE3 and the quad 4 would be the ultimate iteration for handling. Ive never driven one (almost nobody has) so I cant say definitively, hence my mention above of the 245 tire equipped GP. For gen 1.5, Im not sure. For the last generation, its most likely the 2008 GP GXP. The fact they fitted reverse stagger tires (and engineered the suspension to utilize this setup) tells me someone understood how to make an FWD car handle.

It’s been just a little over a year now since I got the Regal…so what better way to celebrate that than with some more recent pictures. Nothing much visually has changed except for the refinished wheels and new tires…which was a fairly large, yet subtle change on its own. My intent is to keep the car as stock as possible, and to keep it up to snuff mechanically to be used as a reliable, fair weather cruiser. And to shake things up…. This is the final picture I ever took of my 89 GS before it was parked for good in summer of 2008.

I like the puddle lights and overall classy/nostalgic look of those Regals. What year is it? I thought all the GS models had a "supercharged" emblem on them somewhere.

91 auto which is what I have in my 91 GP is the AYSZ, AUSJ is the T code engine (3.1) W body for 91, AUBU is the T code engine W body for 93 auto trans these all come out of the 16149396 ECM I have nothing on the ASXJ

AYSZ = 1992 LQ1/Auto BBUK = 1993 LQ1/Manual BCFA = 1991 LQ1/Manual BCFA is the one you'll want to use

If you use your resources correctly, you can get a 3800 for the same price as the 3400. The smart thing would be to look for an S3 and then get an S2 UIM to make it all work. Anyways, the flywheel between the engines are the same. Both used the same 4T65-E trans. The motor mounts should be the same as well. My understanding is that the blocks are the same but the internals are what differentiate them from a 3.1 liter and a 3.4 liter.

Use the trans that is in the 88 and the ecm from the 2.8 as well. If the 95 doesn't have the coolant temp sensor for the Guage/light in the rear head you will have to install a 3 wire temp sensor where the 2 wire is. The throttle cable from the 95 is needed as well. If your '88 has a 3spd you will have to rig up a kick down cable linkage on the throttle body some how. I welded a bracket to the throttle body myself, wasn't perfect but it made it drivable. Sure there may be some other things that I'm missing since it has been about 6 years since I swapped my old lumina!

Welcome to the site - are you thinking of an entire engine swap or just the top end swap? I won't have any answers for you on that but in reading your post I wasn't completely clear. As for the rear suspension, I've been looking into this matter myself recently. Everything on my car related to rear suspension and brakes is rusted beyond recognition (but somehow the body is totally solid!). These two writeups have been Very helpful to me as I've been feeling my way through what my next steps should be... converting to rear coilovers: http://www.w-body.com/showthread.php/37622-Coilovers-Adj-Mounts-Solid-Cradle-Bushings-UPDATE-3-25-Design-Done%21%21%21%21?p=651227&viewfull=1#post651227 and swapping in aluminum knuckles and bigger brakes: http://www.w-body.com/showthread.php/46209-Bob-and-Rob-s-Gen-2-Aluminum-Rear-Knuckle-and-Brake-Upgrade-How-To-with-Pics

any '96-03 3400 will drop right in with the 1st gen OBD2 harness. You will have the easiest time with a '97 system (harness and PCM), I'd go with that. A '96 system would work as well (though it's less tunable should you go that route), but with either setup you go with, grab a PCM from a '96-97 Venture/Montana/Silhouette.

the last 2 3400 swaps I did used 3.1 injectors on stock obd1 ecm's and they both run fine. the bigger injectors will make more power with a tune, but the first thing I would do is start with a better fuel pump. when I first put the 3100 in my old 84 cavalier I went to the track then swapped to a Camaro LT1 fuel pump and went back the next weekend with no other changes an dropped almost 4 tenths off my ET. if I was doing a basic (stock) 3400 swap on a obd1 car I would use 96-99 3400 or 3100 injectors with matching fuel rail (2000+ injectors will not work on stock ecm) or 2.8/3.1 injectors with a 2000+ 3400 fuel rail that has the higer pressure regulator. But if I was mooding a 3400 and dropping it in I would use injectors sized for the fuel requirements of the engine and a full tune.

you will need: -throttle cable and bracket -upper rad hose -coil bracket and module -front pass. side engine mount bracket -ac compressor (not sure if the orginal one will work) -power steering pump and H/P line -brake booster hose all from a 3100/3400 w-body You can get away with running it on the stock ECM as long as you use the stock fuel injectors and injector harness from the 3.1. You will need to change (or have one made up) front pipe/ down pipe to hook up to the rear 3400 exhaust manifold. A 3 wire coolant temp sensor and connector from a 92+ 2.2L Cavalier is the easy way of hooking up your temp guage wire from the rear head on the 3.1\ you will also need a lower rad hose for a 92-93 3.1L w-body The wiring from the coils gets re-routed to the rear of the engine from the front... then its little things like coolant hoses, and vac lines. That is all that I can think needs done right now, but I am sure I am missing a few things.

you need the front passenger side block mount. your ecm will work fine. you will most likely need rad hoses from the 3100 w-body as well. The engine just get any 96 and up 3400, the 2000 and up tend to be better. Its best to get one from a grand am or other car cause that will give you the proper throttle cable bracket on the throttle body.

The '93 3100 used the exact same ECM as the 94-95 models.

LOL I drove a quad 4 Grand prix. it was actually pretty quick. That was one of the VERY few quad 4 w-bodies i have seen. I would like to get my hands on one of thoes. Turbo Quad 4 GTP. i think the one i drove was a 1992 or a 1993 (not sure on the year anymore). it was blue (Very nice condition). It seemed quicker then i bet it actually was. I assume that maybe due to gear ratios being lower so it has more off the line get-up. RedZ

Being it's an I series, that should be the HO quad 4, even rarer!

I would probably keep it as-is just for the novelty of it! A Quad4 W-body is rare enough, a Quad4 5-speed is extremely rare!
