I just got my grand am 2003 for 950$ and it's running great Im totally in love with the car, I replaced the battery for a brandnew battery and now im looking for other stuff to work on since its my first car. So thank you for this! Also my only problem with this car so far is that it needs a wheel alignment and a new sway bar apparently because it does steer to the right slightly.

[@Tennesseealero901]

N body’s are awesome and before thinking about the sway sway bar I’d replace all the end links and bushings like ball joints ..ect, possibly wheel bearing and new tires and alignment first 👍🏼 these cars are pretty old now most of the rubber and tubes are way past the life span 🤷🏻‍♂️

[@HeavyHERO93]

should do one on like fun little addons, like keyless entry/ remote start, maybe upgraded sound systems and stuff. not performance based but personalized. Loved the video, was unaware 4th gen stuff bolts right on, might look into the muffler idea and try to rig something up! and might do the front break conversion! keep it up!

[@KMaffittGAGT]

I did a video on aftermarket keyless!, Will be doing an actual install video for the brakes too!. But I'll take that into consideration, thankn you!

[@Southeast_719carenthusiast]

You ain’t lying bout everything being costly lol

[@rwfrench66GenX]

This is a great video! It’s full of truth and only useful information! No plugs, no tangents, realistic situations with core charges and refunds. This guy needs a TV show! My first car was a 1970 Z/28 I got for $500 in a junkyard in 1982 and what you got for $500 at a junkyard in 1982 was what you get now for $500! Restoring her I learned lessons such as on the brakes the 67 - 68 Pontiac Firebird’s and Camaro’s had 4 piston caliper disc brakes I could swop out, straight bolt on! In 1982 there were plenty of those in the junkyard to raid! Gratiot Auto had cheap rebuild kits so I was all set! I also had a $10 security system! I went to a military surplus store and got a big switch with a lever and an extra battery cable. I took the positive cable from the battery and bolted it to this switch which was mounted under my seat. I took the other cable and bolted it to the switch and ran it to the starter. Whenever I stopped I’d flip the switch and open the circuit. The could steal the radio and tow the car but unless they knew that switch was there they weren’t hot wiring it!

[@KMaffittGAGT]

Just out to share what we find and have some fun with it! Funny thing, the black Camaro in our group had a starter inhibitor switch under the dash at one time! Same thing, just all the electronics came one starter wouldn't engage tho!

[@ryans413]

Your one the first guys that actually done the cold air intake correctly. Most just have the filter in the engine bay which is stupid cause all it’s doing is sucking up hot air

[@KMaffittGAGT]

Before my turbo setup, that's how mine was. No adverse effects, the cold air intake had holes all through the piping from corrosion so I stuck the cone right on the maf. Even had headers! That car I managed a 14.6 in the quarter!

[@martinez1701a]

Its actually ok to do that if you have the ram air hood, just take out the inserts to make it a functional air scoop.

[@martinez1701a]

I actually like these cars they are also easy to work on, i currently own 3 of them one SE and two GT's(all V6) one of my GT's has rust issues so its a parts car Im putting the GT trim on to my SE and im in the process of swapping any parts I need from it to my other two. I also like rebuilding the 3400 its actually a good engine once you replace all the crappy gaskets GM used on it, if you get a grand am first thing you should do is replace the lower intake gaskets with metals one's because the plastic gaskets regardless of brand always fail.

[@rwfrench66GenX]

I had a 94 Grand Am I bought used and the previous owner had a heater core problem but instead of replacing the heater core he bypassed the heater hose. Well, that added extra pressure in the coolant system and the plastic sides of the radiator started to leak and replacing radiators without fixing the heater core was pointless, and I was starting to have electrical issues and with the mileage it was time to either do a full build or cut my losses and at the time I cut my losses. I always wondered what would've happened if I had done a full build on that one though! The sound system in that car was incredible, and the orange tint of the dash at night reminded me of the monochrome screens on the 80's DOS computers. Personally, I think GM should bring back Pontiac to start selling Fieros with Turbo V-6's, Trans Am's, and a RWD GTO to compete with the Challengers you see all over the place! GM could use the GTO platform to bring back the Chevelle SS and that would force Ford to bring back the Torino Cobrajet! Buick could start building the GNX and Chevy could use that platform to bring back the Monte Carlo SS. I think the El Camino would do well too. The thing is, they have electric power steering now, lets just make bigger alternators and make electric heaters so people don't have to tear apart a dash and replace heater cores! If we can add 17 batteries for a stereo we can add another for a heater if it saves consumers $2,000 when fuses are cheap!

[@swaggyswiss1630]

Yeah got a 2004 gran am transmission just failed 110k miles and now valves blew out of the head so now I need 2 heads replaced. I love the car but it’s time for a new one

[@mellonpoop1344]

I have a 2003 SE but it’s a 4 cylinder I’m just now getting into fixing the car up I got it for free last year if you have any other tips I’d love to hear it. Also curious if you’d know if the cold air intakes that fit the v6 would fit my 4 cylinder because I’m entirely unsure and the internet has proven mostly useless for grand am advice. KZbin is my last hope lol

[@martinez1701a]

​@@mellonpoop1344Don't know how far you wanna go with this car but for cosmetics I'd go looking around the junk yard for gt trim and wheels. I'm currently looking for gt trim for my 02 SE V6, also if you're lucky you might find the hood with the two hood scoops.

[@KMaffittGAGT]

Nice, good luck with everything. For boost, either build something yourself or have a shop make a custom setup. Save yourself the headache of running into issue, my turbo setup needs completely redone. As far as number, right now on 10psi it's about 300 to the wheel, it's a fight getting power out of these motors lol you have a nice start tho!

[@jelly_patty6840]

Sorry, don't know if you said this, but will the fender still fit right with the intake? About to buy my grand am in a month or so, so I'm looking for some mods that might help especially with the overheating, and are there any problems with the grand am (in general) that I should know about?

[@KMaffittGAGT]

Yes everything will fit fine. The cone will sit behind the bumper, won't actually touch the fender at all! Check out my playlist of broken grand am, that's all common things!

[@thomascostello4928]

Have 03 GT with the 3400 engine, heard you mention that cooling fans can be turned on at a lower temperature. Would you fill me in on what I could do. Thanks Techman

[@KMaffittGAGT]

Tuning!. I have a video showing what I use, or you can purchase a tuned pcm from wot tech that includes that.

[@jjeremy350]

Car stalls out when sitting there idle no trouble codes? I was wondering could it be throttle body i already changed the idle control valve

[@KMaffittGAGT]

Could be dirty sensors, or a vacuum leak!

[@jaysonburns4423]

I have a 2000 modpe pontiac grand am with the 3.4 and i was wondering if you though upgrading to the msd plig wires is worth it or should i go with the NKG plug wires

[@KMaffittGAGT]

An upgrade in wires isn't a bad idea. Brand is all a preference! Nothing your gonna notice a difference between. Taylor sells an 8mm set for our cars! It's a great budget brand

[@almfmf2932]

i own the grand am 2004 and ive never had a car before but compared to a nissan altima 2013 my friend has ive realized that when i step on the gas on the nissan that it has a way faster respond/delay compared to the pontiac any idea what it could be or is it like that?

[@KMaffittGAGT]

Just by the age difference, that's probably why. Way better technology and I'm sure the Nissan has much more power output. These cars made 150hp at the wheel when in peak shape (from a gt). Stock to stock there really won't be a comparison.

[@UnKnowNxPeRsoN]

Yo man I'm trying to upgrade the throttle body on my 03 GAGT and you mentioned they can be found on Oldsmobile intrigue or Alero. Is that just plug n play or what? Any special modifications required to make it fit/work?

[@KMaffittGAGT]

All the plugs will be the same, you'll need an adapter plate and to modify the cable bracket.

[@martinez1701a]

If anyone has a grand am and is rebuilding the 3400 I made a list of things you should do. 1. Metal lower intake gaskets (plastic ones always fail and restrict air, metal upgrade gaskets match the port better for better throttle response and never fail) 2. Timing set from a 1999 grand am 3400, for some reason in 2000 GM went from a thicker heavy duty timing chain to a thinner chain. Haven't had one fail on me yet but why take a chance. 3. Silicone the pump drive gear that shit always leaks dont just rely on the oring. 4. Drill two or three .076 holes in the thermostat, its just something I do to help keep air out when I purge the system its not necessary. 5. Felpro gaskets! Ebay head gaskets are a gamble they are mostly good but you have a few bad ones out there. 6. This isn't necessary but if your planning to tune and add a bigger throttle body get cylinder heads and lower intake from a LX9 engine, they came in the 04-05 chevy malibu and will have either an 04 or 05 embossed on the intake. You can swap the whole lx9 but its more involved and you need a crank trigger( they're getting harder to find). 7. Swap in a brand new cam or a used one from a 2000 and up, GM had a bad batch and even though its rare I did have one snap it two on me destroying my block. 8. This is obvious but new bearings especially cam bearings(people dont like replacing them for some reason) Oh and brush youre teeth 😁

[@KMaffittGAGT]

Nice! I've got videos on a 3.5 top swap it's a nice upgrade. Timing is an excellent note. I've seen a few 00+ snap. Both our motors have double rollers 😁. Can't stress the metal gasket enough either! The 99-05 cams are all hollow core. It's crazy! Our aftermarket came aren't thankfully! Nice bit of info. Check out the rest of the channel!!

[@martinez1701a]

@@KMaffittGAGT I also noticed with the top end swap the car seems to run cooler, anyone who owns a grand am V6 knows these things run warm you can get a double core radiator from Milzy but who wants to spend that kind of money lol.

[@KMaffittGAGT]

@@martinez1701a there's really no difference to make it run cooler. Probably finally got the bubbles out and a good coolant mixture! I've had plenty stock 3.4s run just find temp wise! As far as the radiator, check out where I found a double core radiator for cheaper!!

[@martinez1701a]

@@KMaffittGAGT really? maybe it was just my builds but every damm grand am 3400 i owned ran warm. The only one that didn't was in a 04 impala, i think it was because the impala has a different cooling setup. Ide like to know where you found a cheaper radiator lol

[@KMaffittGAGT]

@@martinez1701a yeah when the cooling system is in tip top shape they have no issues and don't even get warm enough to activate the fans! My turbo setup ran that way too before the bigger radiator. Check out the video on it! I shared the info all there.

#6 nitrous oxide 😁 can get used kits for under $500 and can get you a solid 35-100 hp! Lol

[@KMaffittGAGT]

Little more involved for someone just starting out. But I believe I may make like an "intermediate" kinda list!

[@ericwest4859]

On the 3.4 u can do the 3.5 heads and intake all fits

[@KMaffittGAGT]

Yup I have a video all about that as well. Theres a GA here in my garage that's cammed with a 3.5 top swap with port work!

[@Kingswood7189]

As the owner of a '98 grand am gt (with the 3.1l v6, smaller bore but basically the same engine), I'd like to turn it into a stock hellcat competitor (it's more or less going to take lots of time and money. Also, I love the hellcat, just cant afford one :)). Im thinking compound turbo with forged internals and the transmission beefed up to handle all that power (if possible). That said, do you have a exhaust muffler in mind that you'd put on yours? And have you disabled the anti-theft system? It's the only major issue I've had for the past couple of years with my car. :)

[@KMaffittGAGT]

4th gens I'm not very knowledgeable on. The security is a different setup and for power yeah it'll take a lot. All the work I did on my turbo GA and it wouldn't touch a hellcat lol

[@Kingswood7189]

@@KMaffittGAGT nice! I'm not sure if it was your GA, but I saw a turbo'd one run low 12s on a youtube video. That said, at potentially 500+ hp and less than 3k lbs, I think I'd have a power to weight advantage. The hellcats a heavy vehicle, but it's a full on beast. :) it's awesome that theres a following for cars like these.

[@KMaffittGAGT]

@@Kingswood7189 that car was built man moons ago and had tons of problems if its the one I'm thinking of. The gm v6 were never designed to be power houses sadly. They say my setup should do 400+. If I had to guess I'm probably around 250 on 7psi!

[@Kingswood7189]

@@KMaffittGAGT electrical issues and leaking intake manifold as far as I know. Aside from that, they're not bad engines. In my experience, the thermostat is not in a good spot, but meh. I can imagine theres plenty of torque steer. :)

[@_Spotty_]

im looking for an exhaust for my 2000 grand am gt and i dont know if i want the monza pacesetter. Any thoughts or ideas what i should do? also what are you running?

[@KMaffittGAGT]

So that's the only bolt on kit avaliable (if it still actually is, long story lol) you'll other wise have to pick a Camaro style muffler and have a shop build the rest. Or watch the Facebook pages for part outs and what not, I've come across some exhausts in junk yards and re sold them. On the black car is an old slp muffler that was specific for grand ams, on the silver body kit car we just built is an slp for a Camaro.

[@_Spotty_]

@@KMaffittGAGT do you thing the bolt on pacesetter one would sound good? or should i just go to an exhaust shop. because iv watched a lot of videos on the exhaust but i want more of an aggressive/loud sound

[@KMaffittGAGT]

@@_Spotty_ it's not bad, very tame and probably not the "aggressive" your looking for. People also report the cheap metal rusts in a year or so. And not just from salt/snow. You'll want something a little more free flowing and remove the resonator. Being a v6 it won't be that loud lol even on my turbo car it doesn't get anywhere near my buddies Camaro.

[@sethnewberry8736]

what did you do with the air temp sensor when you put the cold air intake on

[@KMaffittGAGT]

Right before the throttle body is a small straight piece. That holds the air temp sensor as well as the rear pcv tube!

[@davidcochrane3999]

Does a regular aftermarket air intake for these cars fit on the 65mm throttle body?

[@KMaffittGAGT]

Yes. The intake on this video was later used on a 65 mm

[@mississippiwaterswatters3974]

Does the big brake upgrade work with the stock 2001 grand am GT wheels?

Starfish wheels yes, if they're not chrome. The curved chrometech ones won't work. It's best to up to 17" either way

[@jefferyboat7428]

Pcm tune and light weight wheels sound the best and throttle body sound the best. No final drive mods? Like the gtps?

[@KMaffittGAGT]

Not without tons of fabrication. And then it sticks above the hood. There's a couple people working on making the whole 3.8 able to swap in, which is still a lot of work but more efficient then trying to make the supercharger work. Your better off making a turbo kit like mine honestly, thatd be easier.

wow dude your new to these engines lmao. so 1st mod you do is Intake. you take the entire 3500 intake and throttle body and install it on the 3400. reason being is the 3400 intake from the TB narrows when the 3500 is wide open and can accept a wider throttle body. that TCE you'll never have open throttle cuz the flapper will hit the inside of the intake first. it'll feel normal to the pedal when really you'll have about 25% left but it cant open. the 3500 upper is the same dimensions across all 6 cylinders. I don't think a 3400 upper will take anything larger than a 62mm. lmao your talking about ordering kits and crap lol you need the Plenum (upper intake), the gaskets which are like $10, the throttle body from the 3500. and that's it.

Only been messing with them for 10 years lol. Check out the turbo 3.5 one i built!! lol Funny enough on the stock 3.4 manifold i was doing WOT pulls just fine! but you are right there is not enough material for more then a 65mm. A 3.5 upper is a good one to use i agree! Still need an adapter to use the a compatible throttlebody as they came with electronic ones. So you can't use a 3500 since these cars are cable driven! Be sure to check out the rest of the channel have a couple more builds/revisions coming. this was a quick cheap mod video for those on the pages asking! Thanks for the feedback!

[@panteraa9195]

Buy a real car if you want to do mods. All you’re doing is wasting money. Your mods are actually hurting performance little do any of you in the comments know. 🤦🏼‍♂️ Sorry to break it to ya

everyone can have their opinion. I've tested these things real world in other videos. Have an opportunity to hit a dyno if things line up as well. Its not fun trying to find the parts, and i warn people of the lack of aftermarket for these things.
