Can a V8 replace a V6 3.4L

[tutin12]

Hi guys,

I'm in for a heavy tuning session of my 93' fbird. We're doing everything, from the interior, sound, exterior, wheels etc through the engine.

So far it looks beautiful with over 15k in looks and sound, the only thing it needs is power. Lots of it.

Initally we were thinking of supercharging the 3.4L, but after some thought we came to the conclusion it's probably a better idea to stick in a V8 and then turbo/super charge it.

According to the garage that'll do the supercharging, they can push the V8 to over 600HP and as it's going to be a demo car for them too, I'm sure they'll do their best.

My question is, can a V8 directly be bolted to in the place of a V6 ? Is the transmission different, any possible complications ?

All ideas are most welcome.

No.

You should check with the Advance Section and do your search there. They have info. on engine swap.

I'll make it easy for you since everyone else is always too lazy.

Agreed about searching, but I'm not so quick to say "no". I think a better answer would be "yes, now hit the search button."


Front suspension would be needed, rear springs too, and everything else that is attached to the engine... there's not a whole lot different in the body to make this different. I keep waiting on the update from GM performance on their LS7 "kit" that they say is coming. They are supposed to be working on a stand alone PCM that would make it easier to use that engine in anything. Their project car was a 96+ camaro and got the swap done with a marine based PCM, but even then a Z-28 would be the way to go to begin with.

Better off, though, finding a Z-28 and swapping components to it. After your done with an engine swap, there's really not much of the car left, other than the things that make it pretty, that would be the same. What have you got in the car that can't be swapped to a new Camaro?

To be honest...In my opinion, if your asking questions like this, then you're not ready for this build.

Please ignore the negative comments. check out that TA creations site, it will outline exactly what needs to be swapped, year by year.

a lot of times when it comes down to it, a v8 swap is more expensive than just trading up for a v8 car. if you've already put a lot of money into this one and are dead set, try some searches and check out the above mentioned site, you should get all the info you need.

Good luck with your project.

Re: Can a V8 replace a V6 3.4L

my suggestion is to just find a totaled Z28/SS (like a Z28 with the whole rear end ripped off or something with the front still in tact) on some site/junkyard, and buy the salvagable car for probably 1-3K and there you go.. you have everything you need.. including the wiring harness which is normally really ****ing expensive in itself. You can find good deals trust me.. I was looking into this but I just don't have the money right now.. everyone always says take the lazy route and buy a whole new car.. but most people don't have anything special done to their car. Since you obviously do, OBVIOUSLY you would want to just keep your car and put the labor into putting in the V8.

Just try to match the year.. IE you said you have a '93, just try to find a salvagable '93 with low miles, and take what you need. It's alot easier/cheaper that way then to buy each individual part from say, GM or some other dealer or something.

I'd love to see some pics of this car! Especially with 15K in it! I've only got
3k in mine and it looks great! Can't wait to see yours!

Hi guys,

Just a quick headsup, my V8 finally arrived 2 weeks ago. The garage needed only 4 days to do the complete swap and everything went pretty much flawlessly. Even the V6 exhaust system was attached rather easily with a bit of welding here and there.

Initially the engine ran only at 6 cylinders and the mechanic only realised that after having it run about an hour to warm-up the engine and push the fluids. This probably resulted in petrol entering the engine oil. Last night we put in the optimal amount of oil and when I checked in the evening I had about 2 liters above the maximum (almost an inch higher than the max on the stick). We then drained the extra oil and it did not smell right. This morning I'll check the level and hopefully it would not be above the max, if it is, it means there's still petrol going into the oil.

I only got the bird yesterday and have driven about 30 miles or so around town, but man, do 2 cylinders make a difference.. It's hard to keep it under control and I already feel sorry for my new tires :)

edit: This morning the oil level seemed alright. That's good news to me, looks like at this point there's no problem, we just need to swap the oil with new one. Will keep an eye today and tomorrow that the level doesn't go up.

Why did you spend 15 grand on looks and sound? You Want 600 horsepower? F*** a sound system you won't be able to here it or want to here it. I think a camaro looks fine as it is. I went for a drive the other day and nothing is done to the outside of my car except it is lower a little which changes the look and a GXR 1000 rider threw me the rock sign. Take the 15 grand back and you can hve that engine. A v6 tranny could not handle the power of the engine As well as your rear end. Suspension should be changed, different motor mounts, better brakes to stop the power.... etc

As mentioned, the swap is already done.

The v6 trans is the same trans as the V8's got with the exception of the bolt patterns on the bell housing. The 3800II trans has what is called the "GM Small Corperate Pattern" (AKA 60* pattern) and the V8's got the standard 90* pattern. A 700r4 is a 700r4, and a 4L60E is a 4L60E, parts are interchangable.

And as far as the rears, an open diff is much stronger than a posi AFAIK - you just get less traction on the open.

Many people have swapped a V8 in an f-body and were fine using the suspension. IMO the car actually sits a little better even.

The 4L60E V6 input shaft is also different then the V8 4L60E input shaft.

The 7.5/7.65 open carriers have a habit of breaking the cross shaft the spider gears ride on.

Transmission has of course been changed too, suspension is completely aftermarket (eibach + kyb), antiroll bars, brakes etc...

15k is not that much, when you know the wheels and tires alone cost about 6k. Sound is about 6k too. In fact I should stop here, because I don't think I'll like it if I start counting :) However, I'm convinced I will never sell that car, so all this is not throwing money at the wind, but investing in something I love and intend to keep.

As far as sound goes, I'd rather have a choice to listen to the engine or to the music depending on what I feel like. Having 500-600 rearwheel HP does not necessarily mean crappy sound system, right ? I have no intention to win races with the car, but a bit of fun every now and then on the track wont hurt.
