alright here is the plan to swap the 3.1 engine out of a 92 bird with a 3.4 engine out of a 4th gen fbody and super charge it. i know that it is similar to a 2.8 to 3.4 and that is closest thing i can find on it. I was wondering if anyone had done a switch like that before. And was it worth the switch. And i donnt want hear anyone say why not go for a v8. Because my friend doesnt have the money nor the time. This may take awhile but a v8 would take even longer.

 

Your right in saying that this would be quicker, but only to a point. Swaping in just the 3.4 is a great way to get some more power in the car, drop it in with a better matched cam, and do some head work on it, and i bet you will be able to out alot of the TBI 305s that are still stock. As of right now im pretty sure there is no supercharger kits out there for that engine, unless something came out in the last 2months. There is a turbo kit being made, if you check out the V6 forum, but either kit will require alot more time and money than droping in that larger engine.

But with that 3.4, and if you upgrade it at all, the tranny if automatic will need to be a fresh rebuild, becuase its going to make around 20-30% more power with the head work and cam. just for the engine your looking at $200-600 depening where you find it. Its a simple swap to get it inthere, just pull out the 3.1 and bolt all the stuff over, more than likely you will need to go and have the car dyno tuned.

Depending on emissions in your area the V-8 is actually not all that bad to go with, you just need to get a tranny and v-8 out of a car, preferably an F-body for mounting sake. If you dont have emissions where you are, you can put a carb on it, with a new HEI distributer and your almost done. Its a pretty easy drop in, and you can get all the parts, hopfully good still, from a scrap yard for around $600 depending on your scrap yard. $ for $ the v-8 will be cheaper and make more power, if you wanted to really add a forced induction set up to the V-6.

 

What is the tranny in 3.4 4th gen Fbodies?

 

im pretty sure there is a supercharger kit out for the 4th gen v6. theres this one girl ive seen a bunch of times at the track and i think it has a vortex blower. she only runs i think high 14's

 

I can respect the money thing... but really, if you think it through, the V6-V8 swap is a lot cheaper than V6-Turbo V6.

The Turbo setup alone will cost MORE than a V8 + tranny (assuming you go get some from a junkyard, or from the classifieds in your paper). Not to mention that you would still have to tear down the 3.4, have it hot tanked and magnafluxed, get a forged crank, aftermarket rods, forged pistons, screw with the compression on the heads, have head-work done.

Then you need to beef up the tranny, the V6 trannies werent meant to handle that much power. After that, you've got the typical chevy rear end that's ready to ignite.

Granted, the rear wont go very quickly, since you'll be making about as much power as a mildly worked 350.

Now if all that you wanted to do was a 3.1 to 3.4 V6 swap, that would save you money, a lot of money. No machine work, no turbo-gabble, just slap it in and go.. and since it's a newer setup you'd probably make more horses, as well as more gas mileage.

a turbo V6 swap that will gain you the same amount of power as a V8 swap is what we consider fruitless. Like when you make a 305 go as fast as a L98, if you had done those mods to a L98 it would be wasting that modded 305.

 

you could also try a 3.1~3800 swap like some people I know of around here, or at least one. THe 93 A4 was a 4L60 (IIRC), and the later years had the 4L60E.

There are a couple of turbo kits out there, and RK sport & Powerdyne each have s/c kits for the 3800.

Could I have done aa v8 swap in my ride, sure, but then there's emissions to deal with, getting donor parts, etc, etc, .

If you're on a budget, or even if not, the 3.4 swap with aftermarket parts will give you some good results.

 

ok i think the plan is to get the tranny rebuilt, if a 3.4 will hook up to 700r4? and we do have emission in my area which sucks, and a v8 would be hell cause we would have to switch all the frickin fuel crap, wire harness/computer crap,supension, and that stuff would take hellva lot more than we got to spend were playin with about 1800 i mean that would be a good start for a v8 project, but if we end need extra stuff would have any money. i am pretty sure i can get a soild deal on a 3.4 for around $300- $500 from the junkyard. Then their will be money left over to get the tranny rebuilt. and turbo and super charger (if their is a kit for it ) can be added later. 3800 idea would be badd but if we did that one mine as well did the v8 switch. but thanks for the help

 

fwiw, the v6 tranny will bolt up to 2.8, 3.1, 3.4, & 3800 engines.
fwiw.

 

Are you sure about the 3800?

 

I am pretty sure because 2.8,3.1, and 3.4 are same block, but a 3800 has a differnt block and setup. I am not positive, but let me know if otherwise.

 

I am VERY sure.

this dude actually did the swap before I did, and reused his tranny. Check out that kah-razzzy tv setup on page 4.
I think mine is a cleaner install, but then he's driving his .

 

How emission friendly do you think it is? that is an other thing is to pass emissions or he wont even be able to drive it on the road.

 

we both are keeping the 3800 pcm, and I'll seriously doubt that the 95/96 emissons requirements are less than the 85~92 ones. I'm gonna have to pass the **** e-check in this part of Ohio, and as soon as I get a y-pipe made and retag I'll post some numbers.

Oh yeah, I have to modify my tranny k-mbr a little.

Well i feel that i doin the 3800 switch would be alot harder than a 3400, What you guys Think?

 

a 3400, no. A 3.4 yes. only difference being the 3.4 = rwd, 3400 = fwd. 3.8= 89 TT/A, 3800 = Series II (for this case).

Because of my yr car I had to switch over to a vss ralley gauge cluster. The only things that need to be fabbed really are : block to motor mount brackets, y-pipe, tranny k-mbr tweeked ( spohn makes one that'll fit for like $100 or so) Then just wire the damn thing up.

edit: 3800 rated for 200hp 225 tq. yeah, it's a jab at certain olds motor swap going on

 

My buddy just changed his mind to go with as 3800. So are we gonna have to change the whole fuel delivery system? Are there any kits out there for this? is this a very complicate swith ?

 

doyou want the answers here, or in the v6 scection?
