I had so much casting flash on my intake manifold, had to sand smooth as far as I could reach by hand, did the plenum too. Would have ported but I'd rather top swap first. A.R.E. (American racing engines) also makes custom cams and even stroker kits for the 60°s. Looking forward to seeing the progress.
Thanks for this! Especially about running the bigger cams with a computer. Am working on “stroking” an iron 2.8 up to 3.1, and plan on running the larger Comp Cams setup. Finding it very difficult to locate programming options for these older TBI engines, but you’re giving me hope that I’ll see some improvement without for now while I research options.
The GM 3.1 has a lot of potential for performance upgrades believe it or not my 90 Grand Prix after a full top half rebuild with all performance and bored 60 over with a stroker kit no turbo yet I'm pushing a little under 500hp. Wasn't cheap but very well worth it. If anyone has a 3.1 plenum that says intercooled turbo on it the original one that came with the 3.1 I would pay good money for it to be delivered
Is it possible to add 50+ actual streetable HP on the 2.8 with double roller timing chain, headers, up graded distributer, towing and RV CAM, flow bench the head (port match intake and exhaust ports, equlize valve stem heights, largest valves that will fit, 3 angle valve job, roller tip rockers new valve springs etc...)? Do they make a hydrolic roller cam for the 2.8? If the 2.8 can be made to run normally I would be willing to give it a try. Sounds like a $3-4K project.
I just picked up an 89’ 2.7 Z24 Cavalier I’d love to mod at least a bit to get even a bit more than 135. As my old Fiero made 149 from what’s essentially the same engine.
You will gain a little with better flowing exhaust and cold air intake... but most gains will come from internal upgrades like cylinder heads and a camshaft.
My 3.1 v6 in a 1992 Pontiac Grand Prix will run until it gets to operating temp and then spider misfire and stall out. Then it will not start for a while. I changed plugs n wires and camshaft position sensor and a coil pack but still same problem. Any ideas? I’m ready to sell the car because I’m so tired of nothing working.. some say a vacuum leak which could be but I don’t have equipment to figure it out.
Sounds like a problem I had with one of my old Cavaliers, would work fine until it was up to operating temperature the start back firing/missing and would not start if you shut it off for at least 15-20mins... turned out to be a bad coolant temperature sensor, it would short out when up to temp, and read -40 on the scanner. Next time it won't start, try unplugging the coolant temperature sensor, and see if it will start for you! Or just put in a new sensor to rule it out, I don't think that they are too expensive!
Anything to know about on the 2.8s and 3.1s I just bought a 87 celebrity eurosport 2.8 and got it running&driving after 7 years it's all on my channel but it needs a timing chain kit bad cause it hits the cover u can hear the slack in it lol . She has like 235,000 miles . I also need to chnage trans fluid cause it slides into 2nd so that's not good
Wow, surprised it didn't jump if its hitting the cover! You should be able to use the LZ9 3900 timing chain tensioner on it if you wanted... I will have to check out your videos!

Throttle body upgrade is probably the simplest to do, or you can do the 65mm like I did in another video. Upgrade the exhaust to a 2.25" or 2.5" free flowing setup. Headers are great if you can still find them, and have someone with HP tuners do a custom tune on the pcm. Other than that your looking at porting and polishing, cam upgrade and turbocharging!

All depends on how much money you want to spend and how much power you want. You can get more power from the iron head 2.8 like you have but for same money you can swap to a 3400/3500 and have more power! Unfortunately I have too many projects on the go for this year to keep me busy lol
@@modeverything1 I have been told the 3.4 is as close to a drop in as you can get. I was also told there are popular hationwide builders that will do some mods (cam and head work) as part of the order for the motor. If I can source a built remanufactured 3.4 would you do the swap.
I have a 91 Lumina with a 3100 can I use the heads and intake off of a 3400 or 3800 all the stuff is very easy to get cuz of my friends wrecker yard I can also use the throttle body off of the 34 38 right but not with the 3100 intake and to change the intake I have to change the heads am I correct. Does it make more sense to buy all new bigger injectors or just go pull used injectors out of a 3400
91 should be the gen II 3.1l. 1994 is when they started getting the 3100's. I put a complete 3400 in my old 1992 Lumina it worked great! Yes you can use 3400 heads/intakes on your 3.1 but you will need more than just the heads/intakes. You will need a throttle cable from a 3100 lumina/Grand Prix/Monte Carlo, 3 wire coolant temp sensor from a 2.2L cavalier iirc, egr you will have to make an adapter or try to wire up the newer style, if you have a 3spd trans you will have to rig up a tv/kick down mount on the throttle body. Check out this video to see what I did on mine ua-cam.com/video/yAQ4U2TsfVM/v-deo.html This was with the 3500 but its only a few differences from the 3400!
@@modeverything1 sounds good this 3.1 had low miles it was already swapped 10 years ago or so and hasn't been on the road a lot.

Ill let you know how it goes mainly just trying to get the 3400 throttle body and injectors and take the other 3.1 intake and modify it dont wnat to tear into the heads if nothing is wrong at the moment.
There is lots that you can do! I would start by making sure the tune up stuff is all good, spark plugs/wires, fuel filter... then look into higher flowing exhaust and air filter. After that you're moving into the engine with upgraded camshaft, cylinder heads, intake manifolds, throttle body... After all of that you will want to look into getting the PCM recalibrated for the improvements. Even if you just do exhaust and air filter a performance chip/ecm recalibration would help!
N/A with cam, ported iron heads, headers and throttle body upgrade you could probably get around 200 crank hp without going too crazy. If you went turbo you would be 240hp+. If you wanted to swap to 31/3400 heads and intakes you would pick up at least 25hp from the start before doing anything else!
Depends on the year of the engine, but pretty much all the same things you can do on a 3400 in a Grand Am or Alero. PCM tuning helps alot, headers, exhaust, Throttle Body (56mm or 65mm). Then from there you can get into the engine with porting heads/intakes, and installing a performance camshaft!
Mod Everything engine year is 2003, been doing a lot of research for my 2003 Chevy Malibu, I’m not sure what pcm tunes to get and headers are quite hard to find especially for the tight fits
i can't imagine paying all that money for extrude honing and then still having to touch em up by hand. i was expecting a lot nicer results from the extrude honing but you can still see casting lines and everything.
They looked awesome in 2002-2003 when I first saw them, but I was just getting into performance on these engines. I believe they probably could have done another pass through with the abrasive, but I don't think its cheap, and I don't think it would have done much better.
If I was going to do a budget set up for 300-350hp I would use a Ebay/Amazon gt3582 turbo, late 90s 3100 w-body exhaust manifold with a custom crossover or 2 front 3500 g6/Malibu manifolds. Then you would need larger injectors, pcm tuning and a intercooler! *little more involved than that but it gives you a start!

Springs are the same from 1994/5 and up 3100/3400. Also the same on the non vvt 3500 (LX9) as for the valves 3500 LX9's are the best "drop-in" OEM but the valve seats will need to be cut to match the larger intake valves!

@strange_waverly you could always get a 3.1/3.4/3100/3400 crank and 3.1 rwd pistons to put in the 2.8 block. That would at least give you some more torque
What transmission do you have now? 3spd or 4spd? I'm not to too sure on what is a direct bolt in but you could upgrade to a 4t65e or a 4t65e-HD if you are planning over 300hp!
@@modeverything1 not positive. But I believe it's the th125. Numbers on the the top of the bell housing are 739. Just looking to be able to tow my boat and trailer.

I would put a good size external cooler on it and try it. The 3t40 in my old lumina took a beating almost daily behind a 3500, and I loaded It up with parts for swap meets several times!
@@modeverything1 ok. I'll get it to the scale first. If it's under 2000 lbs I'll give it a try. Just not sure on strength of the transaxle. I just bought it.

I couldn't quite hear clearly but would the older 3.8 injectors fit also?
Yes you can swap to 3100/3400 heads but you have to use the matching intakes to the heads. The ports don't line up with the 3.1 heads. Push rods are also required and usually custom. I will try to do a video explaining this soon!
It is especially with a cam upgrade. You can use any 3400 top end, the only issues would be with the egr valves being different. Someone used to make egr adapters but they haven't made them in years.
I can make a little plate and delete the egr all together but that's crazy if your saying I can run a idk 2000 3400 top end on my 94 3.1 engine that's awesome n prolly worth doin gotta look into the push rods and how to measure them will be waiting for your videos
Ah even better then so I can find like a 2005 3400 sweet but the push rod thing you mentioned will be the confusing part im shocked I can use such new stuff on a old block
The only thing you would be able to do on an iron head carb setup is use the better exhaust manifolds. Its been a long time since I have looked at the iron head stuff... but you may have to elongate a couple of holes on the manifolds to get them to line up correctly. You can do some porting on the heads but even after porting they are only slightly better than a stock 2.8/3.1 head.
There are a few things you can do, just depends how much you want to spend. Check out the v6 section on thirdgen.org forms, you will find lots of information and can see what kind of results you can expect from certain mods! Hope this helps for now, I may try to do some videos on the iron head engines down the road.
Hate every car that these went in, but BRILLIANT engines that have a cool sound.

Ah even better then so I can find like a 2005 3400 sweet but the push rod thing you mentioned will be the confusing part im shocked I can use such new stuff on a old block

Can some of these mods be done to a FWD HO Carbie ??
The only thing you would be able to do on an iron head carb setup is use the better exhaust manifolds. Its been a long time since I have looked at the iron head stuff... but you may have to elongate a couple of holes on the manifolds to get them to line up correctly. You can do some porting on the heads but even after porting they are only slightly better than a stock 2.8/3.1 head.
@@modeverything1 would there be anything that could be done with the intake on the carbie ??
Think Edelbrock made an Intake manifold for them years ago, but they are getting hard to find now. IIRC it was setup to run a small 4bbl carb!
@@modeverything1 it would be nice to wake the old H.O. up. 130 HP ain't enough. Lol.
Ay how can I make my 2.8 mpfi in my 1986 Pontiac Firebird faster
There are a few things you can do, just depends how much you want to spend. Check out the v6 section on thirdgen.org forms, you will find lots of information and can see what kind of results you can expect from certain mods! Hope this helps for now, I may try to do some videos on the iron head engines down the road.
