    Old to W body's, new to this forum

    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!

    New here with a 03 Monte Carlo SS

    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.

    OIL LEAK - 1994 Cutlass LQ1

    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!

    Firmest front springs for a first gen?

    Automatic equipped FE3 springs from a 3.4 DOHC car seem to be the stiffest. The manual trans springs are slightly less stiff (as compared side by side, and they have different part numbers). In other words your automatic Z34 has the stiffest ever available factory.

    I know it's been done before. I think the biggest issue is always switching the vehicle over to OBDII. But if you aren't going for a Series II L67 a Series I L67 from a Bonneville that is OBD 1.5 might make a better option.

    OIL LEAK - 1994 Cutlass LQ1

    UPDATE - I believe I may have found a shop with a mechanic having the experience to have worked on these motors that will do the job. My first hunch was to go to a Chevy dealership as the Lumina had these motors as well, those Z-34's you almost never see (?). As soon as they found out I was in no rush to get the car back, they were more open to the idea of working on it. I guess they thought I wanted it done yesterday. Not the case, anytime between now and July 22 will do........ Stay tuned

    I've ground the top ridge of the pump drive down slightly to allow for more room to work, then use a distributer gasket for a Lumina van with a 3.1, just give it a cut and slather it in RTV, seems to work well. and I'll be damned if I'm pulling a head just for that.

    1992 Cutlass Supreme Coupe Door Speakers

    I think the mounts will fit the doors, but I don't know that they'll fit under the door panels. 95-96 used 5.25" in these angled enclosure pod things that stick out quite a bit while 88-92 used 4x6's on a flat plate.

    Draining Gas Tank - 95 Regal

    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.

    Draining Gas Tank - 95 Regal

    The fuel lines that feed the fuel rail are not screw on nut fittings, both the pressure & the return are disconnected with a set of fuel line/ac disconnect tools. The pressure line is near the centre at the back of the engine. One pulls off the engine cover & you'll see the fuel rail. Once you've disconnected the line you'll need a lengthy section of garden hose to slip over the fuel line end & tape it up to prevent any leaking & feed it into a container size of your choosing. Now you can bypass the relay to power up the fuel pump to drain the tank.

    Welcome! I remember when those were your everyday generic GM car back in the day (`99-`04ish) but they really stand out now. 70,000 is great mileage considering the age and the only real problem spot on that 3100 is the LIM gaskets. Flush the fluids and keep the oil changed regularly and there`s no reason you couldnt see 200k on the OD if there isnt any rust. It looks like a brand new car from the pics, and that makes it extremely uncommon to rare nowadays. Great pics with the city background. What town are you in?

    3.8sc swap into 94 Oldsmobile cutlass Supreme convertible

    Here is info for the the swap based on my own experience of swapping my 88 cutlass w-body. 3800 swap w-body From 98/99 Monte Carlo z34/lumina LTZ with 3.8NA Needed - power steering lines (buy new) - Heater hoses (buy new) - Exhaust downpipe (or have one made) - AC system - all lines/parts from the engine bay (compressors can be from the gtp too) Best to have from the Monte Carlo/lumina but not mandatory - engine bay wiring harness - Cv shafts (buy new if you don’t have them) From gtp donor - motor - Trans - Trans cooler lines - rad hoses - Motor mounts - Cv shafts - PCM - Engine bay wiring harness Notes: cv shafts if using an HD trans you need to use the gtp passenger inner with the 1st Gen shaft and outer joint. If you get them from the Monte you can use the stock Monte drivers side. Wiring: if you can’t find the Monte Carlo harness you can use the gtp harnesss, and merge it into the 1st Gen c100 connector. With the Monte harness it comes with the c100 you just need to remove a few pins around and overall much easier but can be hard to find. You’ll need the GM service manuals for your donor harness and your original car to match the c100 connector. If using a Monte harness you will probably want to add the BBV wiring. This will also convert the car to obd2 PCM: you will need to get the vats/security removed(it’s possible it won’t be an issue but be aware it probably will be) and probably want to remove a few other codes. Rad: you could use your original, but the donor gtp rad will be bigger and fits into the chassis. I’d say it’s recommended but not 100% necessary.

    Rear Speaker Change- 1994 Cutlass 2 Door

    I do not believe that the 1994 Cutlass Supremes had the "Audio Bass Control" slider switch as an option, but I am not certain of this. The slider was located below the fog light button if the car were so equipped (there were two versions of the fog light switches). Here's an image of one (sorry it's so big): If the car was equipped with this feature, it also had a small amplifier located behind the dashboard, to the left of and slightly below the instrument panel. My 1992 Cutlass Supreme was pre-wired for this feature. The harness was folded and taped under the dashboard. I had a hell of a time getting the amplifier out of a junkyard car. The slider does definitely make a difference in the bass response in the 6x9s. It's been a really long time since I've posted here. I still love this site because it hasn't changed and people are still tinkering with their Ws.

    Firmest front springs for a first gen?

    I did a bit of digging on this a while ago and unfortunately if you want to change anything about the suspension rate in these cars now past what FE3 gives you'll either need to contact a spring shop or figure out how to fit coilovers on the car. There were custom coilover mounts available here but the last batch sold out years ago. I'm sure there are springs out there that fit the car and provide a stiffer rate than stock but as far as I'm aware nobody has come across ones that fit.

    There are no longer aftermarket *performance* springs manufactured for the 1st gen W's, if you've got the FE3 suspension under the car then you've already got the stiffest springs available. I take it that you want lower the front to match the dropped rear's ride height?

    Gotta love that quality 80s GM fit and finish! And that Regal is very oddly equipped. Bench seat, manual locks and windows, no rear reading lights.....but it has alloy wheels. Then there is this: That cluster must be from a pre-production vehicle, as the tach was never red like that on any of the production ones. My old 88 Regal was a November 87 build, and the tach was green like the rest of the cluster.

    Swapping 2.8L for 3100

    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

    3400 Swap done!

    get it tuned and at a minimum, adjust the TV cable so it shifts later, the LA1 makes more power past 4700, think more along the lines of a 6000 RPM shift. better yet would be to replace the th125C with a 4T60-e

    3400

    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.

    3.1 to a 3.4 i want power?

    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.

    3.1 to a 3.4 i want power?

    keep it simple and just bolt in the 3400 its less power than the TDC but less weight too! I would just use the stock tranny to keep cost down. you will need the front pass. side block mount from a 3100 equipped w-body because the bolt holes are in different spots, at least just on that spot of the block. use a coolant temp sensor from the 3400 (3-wire ) and wire up the temp guage to it insead of the back head cause the 3400 has no hole for the sensor. you will also need a throttle cable and exhaust manifolds for a 3100 w-body. Most people use the 3.1 injectors and harness when they do the swap untill they go to tune it. stay away from the '04+ 3400's in the equinox (I beleave it is) they have a plenum that faces the opposite way and a different crank sensor pick up on the crank that will not work with your 3.1 ecm. that is all that is comming to mind right now.

    MPFI to SFI

    I was the one doing that swap, and if you're going to run a 3400 it's definitely worth it. You don't want puddle fuel injection on a 3400. The hardest part in your case would be repinning the C100 connector to your car's pinouts. Also, if you plan to use the same tranny you have now, that will require doing wiring changes on the harness, or you can just use the tranny for the 3400, and you're set. There really wouldn't be much more beyond that. Mine was a PITA because I had to convince my ECM that it's controlling a tranny when it is in reality a 5 speed.
