my car is a 02 and im looking at v6 swapin it i read the sticky on it but still was a bit un sure

can i just use a Impala ECM and bcm

looking at 3100-3400 swap

Use the wiring and PCM from an impala, the BCm from the jbody.
You going 5 speed or auto?

since you have an auto, the answer is no. You can not use the Impala program with your factory transmission. Your options are to swap transmissions or use a different computer.

You can use the impala pcm and reflash it as an 05 Malibu.

im a eco so ill have to swap trans too

so if i get motor/trans motor bay harness and ecm from a 00 impala it will work


im really wanting to go 3400 im opend for input on a better way of doing this

Does the '05 Malibu not use the 4t65e? Also, has this been tested with the gauges and do all of them work? The issue with many of the flashes, for some reason, is the fuel gauge.

Yes, it will, but it will not run the J-body transmission properly. You will need to use a different flash (I'm interested to hear gtpsunfire's response) that can work with the J-body tranny, or swap in the 4t65e, which will require fabricating mounts. As far as the engine is concerned, getting the engine and harness from the Impala is fine.

3800 supercharged ftw.

what happened to your eco ? wasnt it being built?

on a 3400 say i got the motor and transmission with ecu and harness your sayin all i have to do is make all my own mounts and i can run a 00 impala ecu and it will run fine im allmost sure this is the way i want to go as plan jane 3400 are cheeper and eazyer to come by then the 3.8sc and i plan on beating on it and maybe spay too so i thank the 3400 be my better way to go eazyer to get parts



and as far as the ecotec
i turbo it but i end up lookin in to the power i can make with a na v6 with just bolt ons and i thank this will be a better way for me seens my soon to be wife drives the car as much as i do a na motor will be less to worry about

Piss on 3800.

60º V6 FTMFW!

If you use the Impala engine, ECM, and tranny, all will work fine. Pick up a set of my upper and lower engine mounts, and all you'll have to fab is the tranny mounts (talk to Lenko, as he's put this tranny in a J already), and it will all work great. We know that the Impala flash runs the 00+ J-body cluster fine. The only issue it's got is that it will not work with the 4t40 transmission.

sweet i cant wate

Instead of the 3100 and 3400, which are notorious for intake manifold gasket problems, can a newer 3500/3600 or 3900 be used? They are much more powerful than the older engines...

3100 140-170 hp, 170-190 tq
3400 170-175 hp, 195-205 tq
or
3500 205-224hp, 214-220 tq
3600 252hp, 251 tq (G6 GTP)
3900 233 hp, 240 tq

HP and TQ varies by make/model of car between Chevy and Pontiac. They would be more expensive than the older engines but as seen above are much more powerful. I also believe the newer cars have been cured on the intake gasket problems the older engines had.

As a bonus...the G6 GTP engines comes mated to a 6 speed automatic.

Ok I wont debate that the fastory LIM gaskets are know for going bad. But why would that even be a deciding factor on which motor to use. A $90 set of felpro permadry problem solver gaskets and it will never leak again. I am absolutely blown away at the amount of crap the 3x00 engines get for such a stupid and easilly fixed issue. End rant.. Main reason I could see not to go with the newer style 60* v6s is probably availability and cost compared to the older.

3x00 have a ton of potential and being they have a few years on them are gaining some aftermarket support now. The electronic aspect of it would push me to go 3400 with a couple select 3500 parts and a healthy cam.

I believe I fixed that for you.

I would never put dexcool back in anything if I had the system drained unless the customer asked for it. Plus the permadry plus metal framed gaskets are far superior to the plastic framed ones.

im going 3400

whats this you talkin about a few 3500 parts plz go on

Simply put, the newer 3500 is VVT, and not the same engine at all as the 3100, 3400, and even the first gen 3500. The 3500VVT and 3900 are their own animals. They have a slightly wider piston spacing, VVT, and use highly proprietory electronics which are not compatible with many vehicles. It could be done if you want to swap the body wiring from the donor car. However, AFAIK, there are currently no tuning systems that have addressed these yet, so it's not easy to delete codes, etc., and set them up to be stand alone. Basically, the ECM needs to think it's in the original car, so swapping over all electronics would currently be the only way to do it.

The 3600 (and 2800) are yet another class, not even sharing the bellhousing pattern with the rest of the 3x00 engines. They share the ECO pattern, from what I have seen.

Now, that being said, I'm sure any one of these engines could be made to work on older electronics, by locking the cam, and putting an external crank trigger on, and adapting the intake to accept a cable drive throttle body, at the very least. I haven't looked much further into it than that, but those three things would definitely need to be addressed.

Swapping the heads and intake manifolds onto a 3400 (heads can NOT go on a 3100) yeild a significant increase in power, because they flow much better, and the valves are larger on the 3500 heads (this is why they will not go on a 3100, because the valves will contact the cylinder wall). The heads will drop the compression, but if you were to swap iron head 3.4 pistons in, you'd end up with a net compression gain.

Also if you wanted a true dual exhaust you could run the 3500 exhaust manifolds off a few different cars since they dont run the 3x00 crossover pipe. Just a thought for ya.

a saab turbo eco will run faster then a 3400 if you have an eco you would be foolish to switch theres more power to be had in them if you had any other engine switch it

3900 is too long would require a bit of work to install along the lines of the n* engine 3.6 shares the eco pattern but have timing chain issues

stick with your eco

Are you sure about this? I've examined a 3900 sitting on a stand, and the only possible thing I could see is that the VVT module might hit the frame rail, but I wasn't 100% sure that would even be an issue. Also, if the 3900 is too long, then so is the 2nd gen 3500, since they're the same as far as the long block goes, and both have the VVT.

be nice if someone knew if the 3900 would work if it will work with the eco trans being my trans only has 40000 on it lol i would go 3900

will a 3400 motor and trans out of a 2000 alero work for my swap with a 00 impala ecu and wires

theres a wreaked 00 alero in the yard with a good motor and trans i can get cheep all its missin is upper intake and fuel rall

Swapping the heads and intaNothing, it's speed density. I can get it do do calculations off of either the ke manifolds onto a 3400 (heads can NOT go on a 3100) yeild a significant increase in power, because they flow much better, and the valves are larger on the 3500 heads (this is why they will not go on a 3100, because the valves will contact the cylinder wall). The heads will drop the compression, but if you were to swap iron head 3.4 pistons in, you'd end up with a net compression gain.

04-05 Mailbu/G6 has a non-VVT 3500. The top end will swap onto a 3400 block. You can use a whole 3500 but you have to have an external crank trigger to use with a 3400 ECM. Additionally more mods are needed because the 3500, ANY 3500 is DBW.

I have a set of 3500 (non-vvt) heads/intakes here that I STILL have not swapped on. They will not work on a 3100 because the valves are too big for the bore on the 3100. But it does clear the 3400. It will reduce compression.
