what ever happened to this thread?

Guest

Why, you wanting to try it?
The whys and why-nots of the 4.3 have been covered in several threads.
Also, it looks like your sig has a typo, your '94 would be a 3.4, not a 4.3, and the 3.4 swap is super easy, I've done it and am daily driving it.

kmcn47

i'd love to have the money to do it first , and yepp typo thought it was 3.4 sorry, but this is just a thread i found by clicking the "last" button on the v6 board, so is this the best thread that pretty much covers it?

It seems the OP went AWOL after the 2nd day of intense scrutiny...

I saw some interesting pictures of Wurtle 38's car, which are the only ones I have ever seen of the 4.3 actually in a running condition in a third gen.

Maybe the wiring caught fire and burned that car down? It looks like a possibility from the pics, anyway!

I wish someone else would finish one, from start to finish, so that we would have a reference point.

I'll add it to my list of things to do when I get home hahahahahhah.

kmcn47

i see he hasn't been o n the site in a year and would love to know the status of his car, as he said he had it running sort of, i wonder if he ever finished, and why he left, but at any rate it is by far and away an interesting idea, i dont see any reason why with enough money and time it couldn't be done but i know that i have neither at the moment and my car is DD so i am not trying anytime soon, but i love the things i'm finding out about gm v6s while looking for what to do to get myself a badass 6 in my bird, the 2.8 is okay, but i want something with a little more "bragging rights"

It seems there are two "established" routes to do V6 power with awesome results on this forum:

1. Turbo Buick V6 cars, similar to the Turbo Trans Am

2. Hybrid 60 degree V6 engines, with a rear wheel drive block but the front wheel drive top ends from newer front wheel drive cars. I have seen a guy or two with complete front wheel drive 60 degree V6 engines under the hood.

In your signature it says that you have two cars, so maybe you should take one off the road and start your dream project?

kmcn47

love the hybrid swap, trying to get everything together for a 3400 swap on my 2.8, and the camaro is being rebuild after blowing the valves and head gaskets as we speak we should have it back by the end of next week maybe sooner, the guy rebuilding it works at the junkyard where i plan to get the 3400 from

So, no more 4.3 swap plans then?

Dare to be different with a 4.3.I dare ya:

Total parts differences OEM.Long but a worth while read for 4.3's.Has some tips and tricks:

You want to know why??. Well yrs ago when NASCAR ended their class for V6's,at the Indy Drag Racer's auction I bought a Bowie block forged 4.3 common pin crank race set up.What did I put it in??. Well it was a Chevette that I built everything from the motor mounts to the slip fit headers.Ran the car in the 10.90 class holding it back on a throttle stop,it ran the number like clockwork.Had a custom built welded intake running into Brodix heads with I think it was 2.10 intake valves and 1.65 exhaust.Guess what??. Everyone told not to build that...........................But that isn't the laws of a outlaw.

BTW:You can still find deals on parts for the 4.3.This stuff isn't mine,but not a bad deal for what you get.Trust me-a race set up ride with a 4.3 for those of you who never has gone that fast is a eye opener.

This is in part the holy grail for 4.3's. I heavily suggest if you have any interest in 4.3's you bookmark the links.

So, are you going to replace your Chevette now with an 85 Camaro? I hope so!!

Don't forget to take lots of pictures...

1gary

Naw.The Chevette got sold as a turn key yrs ago.I am just passing along some stuff on the 4.3's and making the point that outlaws are leaders and not followers.

if you're gonna race the Riviera...why not fight fire with fire...find a newer donor car and put a SC 3800 in your car? its not about what it makes stock, its what it CAN make. go on a Regal GS or Grand Prix site and just read about what they are getting out of them. you'll be impressed...

I'm on with that! That's why I'm doing my own standard shift turbo Buick power plant...

fireburdluvr85

always wondered about the 4.3. all you would need is the motor plate adapter from a 88-98 c1500 with a 4.3 in it. that takes care of the bolt in aspect. i saw a supercharged 4.3 in a 98 blazer with around 350 hp on low boost settings. pretty interesting.

Wurtle38

the car didn't burn down but I had transmission issues, and fuel pump issues. fixed the fuel pump with an inline. then put a 700R4 in it to replace the 4L60E and then went to start it and the new fuel pump didn't work. so I'm thinking the car is cursed it always has problems so I'm trying to sell it for $800 on craigslist. my MR2 is more fun anyway

1gary

The oil pressure switch shuts down the fuel pump if it isn't hooked up correctly.Get a factory service manual the electrical suppliant(sp) for both the car and for the donor vehicle and repair the harness.Or get a pick and pull harness and start off fresh adding to that harness without tear it up.Those manuals are cheap on Ebay.

I think you said the engine came from a 2000 donor.The would be the later model computer system that you would have to convert to and doing so would allow you to use your 4L60E trans by using the VSS.Look at this way,if it ran in the donor,then it should work in the car if it is put together right.You need to get the donor computer to wire that in.

Precisely. I had the same exact issue with my new fuel pump. About a month ago. So I built a jumper wire, 2 male spade connectors on a 3" length of wire. Then just unplug the connector from the pressure switch, and plug the jumper into the connector.
If I had $800 and lived closer...that's a steal for any '94 F-car.

Wurtle38

I used a summit fuel pump relay. don't remember the brand of the pump. wiring was fine. pump failed bench test. think it was the old fuel but I had a filter right before the pump. so I don't know. got 6 cars trying to get rid of 2 of them.
another issue was the pass-lock II system so I had to have the ignition switch from the 2000 blazer to start it. and I couldn't find an aftermarket computer or anything to get rid of it. all kinds of support for using corvette engines and just about any V8 but not much aftermarket support for V6s

Wurtle38

I'd like to sell it to someone that can do something with it. don't want to scrap it. body is in good shape with no rust and has the T-tops.

1gary

Can't help anyone who has given up.Early on I learned a tough lesson.Did a swap and got frustrate with it.Sold it off to a neighbor next door.He got it sorted out in 1/2 a day and I was sooooooooooooo close that it was a embarrassing.Aaaaa yes those teenager learning curve yrs for me was hard lessons learned once.

kmcn47

if i lived anywhere near you even states away i would buy it, i mean a sport coupe with a 4.3l ..........albeit not quite running it looks as though it could be sorted out and then i'd devise a turbo setup for it

Hey guys, I have news for you, I put a typhoon motor in my 91 bird... went together surprisingly easy for me, I am very inclined though so I don't know how difficult it would be for your average joe but I still dont think it be that bad for someone. i was very happy with how that bird ran with the turbo 4.3 liter in it

KrisW

iTrader: (5)

fbirdroller, I wish you had some good pictures of that 4.3 turbo setup for us to emulate!

I know, I did the same thing before too. I put a Buick 350 in one, and an Olds 350 in another, no pictures from me either. That was before I had internet, digital cameras, or really digital anything!

If you do another one, do a thread please!!

I am looking into doing this this summer, any new info?

not to bring back the 4.3 gas mileage thing but your comparing mileage between a thirdgen and astro van or something of that sort. which im guessing is slightly heavier than a thirdgen. so with less weight and more power it takes less work for the engine to move the car. not worded correctly at all but you get the jist of it. no one can say anything until this swap is actually done and tested but i think the power/fuel mileage ratio would be pretty good in a thirdgen

never noticed how old this thread was

Pics I need to know which holes to use on the frame to mount the motor to
