engine swap

Post by sitarski » Wed 16 Jan , 2013 5:41 pm

Will a 2002 6.2L Hummer engine fit into a 1993 Hummer?
That is, what modifications would be needed, if any, for this engine (2002) to run correctly in a 1993?

Thanks
Dave

The 2002 is an electronic turbo diesel. You would need a different ECU (computer) and a trans. I believe the trans in a 93 is a 3 speed. You need a 4 speed 4l80e for the new engine. you will also need an output speed sensor in the transfercase. I doubt the 93 has that. They also lifted the truck so the turbo would fit.

Thanks, that is the info I need.
I am looking at a 93 in Denver, open top. Just was on e-bay but failed to sell.
I have looked at the vehicle, started it, starts fine, still need to drive it and look it over more.
CTIS has been de-activated, compressor still comes on, A/C belt is off.

Any other info apprciated.

I think the 93 came with the 6.2L Diesel and the 3L80 Transmission.

unless you have all the tools, shop and "TIME" for the swap, I always found sticking to the stock set up is much more fun and enjoyable .... the H1 is a blast to own.

You can always mod it up once you have the truck in dependable working order.

The CTIS is easy to fix once you you wrap your head around it. The A/C is like most vehicles and can be worked on at most A/C shops.

Do you need A/C in Denver?

let us know when you buy it.

Thanks for the help.

I am taking my time.

No, A/C is not a requirement in Denver. This vehicle is for sale at a small exotic car dealer. They have had some luck selling a few other H1s. I do not beleive they know what they have gotten themselve into with this one. i.e. their listing is incorrect about many features on this vehicle.

Onec agian, thanks. This is the best forum

another question?

Was a non-turbo engine offered in 2002?
Or
could a 2002 turbo be changed to a non-turbo by swapping the intake from the 93?

Looked closely at this 93 and I did not see the turbo, the intake comes right from the cleaner to the manifold.

There weren't any Hummer turbo diesels until 96. By 2002 all the engines were turbo diesels. Hopefully the price on this truck is really low. Just buy a built up non-electronic 6.5 NA diesel. NA means naturally aspirated which is an engine without a turbo.

I can tell you one thing. Unless you are doing the work yourself at the end of the day you won't save any money. By the time you buy this truck, buy another engine, pay to have it installed and deal with all the other problems you'll have with a 20 year old vehicle you will have more money in it than it's worth. I'd simply decide if this truck the way it is, is what I want and what I can afford. If not look for a truck that is already what you want and if you can afford it buy it.

Realize that hummers are expensive to maintain and heavy to work on. One tire and wheel on that 93 if it's stock weighs 160lbs. It probably has 16.5" 2 piece steel wheels and tires. 16.5" tires are difficult to get and each hummer tire costs around 350.00 each new and you can't even get decent 16.5" tires anymore. Then you have to look for 17" wheels which are difficult to find used because everyone else is dumping 16.5's. A set of 4 new 17" wheels with tires can easily cost 4500.00. Adding insult to injury in most states you can't just junk the wheels because of the rubber tires. That means to legally dump them you have to take them apart which is a major job, and drop the tires at a tire place which will cost you a small disposal fee and then dump the steel wheels in the garbage.

Makes the H1 even more a exotic, like a Lambo ..... “Its not for everyone” and “Not anyone can have one” .... it will always draw a crowd.

as far as dumping the wheels, keep them for the factory stock look. You could always make tables from them “Have fun with it”

Is it that Red one with 1/2 soft doors?
if you have the resources to refurbish it, it will be a real show stopper.

Thanks for all the input.
I am passing on this vehicle.
I live at 8000' and turbo is a must. Not looking for a show vehicle, just a great off road and snow truck.

It is the red rag top.

I've spent a lot of time over the years in colorado. I've been up in the mountains with gas trucks and na diesels. An na diesel or gas truck is only going to do around 45 mph going up Loveland pass or on 550 between Ouray, Silverton and Durango. Running trails out of Ouray an na diesel is going to be blowing a lot of black smoke and won't get up a steep hill. Like you said the turbo diesel is the only way to go when you're at altitude. If you want to see a lot of pictures of the Hummer all over Colorado check out my photography page.

You need to find at least a 96td that's had it's engine already replaced.

Thanks Chuck,

I have looked at many of your photos. Great stuff. I will keep looking for a Turbo. I have read the articles about the engines as well. Again great information.
My current rig is a 76 Scout II. Another incredible off road vehicle.
