he happens to own WOT-Tech, which is that nice banner you see near the top of the page.

Who's Ben?

[robertisaar]

as per my own rules:

ask Ben about tuning.

he should be able to hook you up with a good tune...

[2.8 Grand Prix]

Ok,
How do you tune the ECM? Is it very hard?

The 3x00 has a MAF and I think the 2.8 does too.

[robertisaar]

...by ECM if you mean all of the connections, then yes except for coolant and EGR... but those have been worked around...

what ECM is it? namely does it have a MAF or MAP sensor

yes, you have a 4 speed (4t60, th440-t4 whatever you want to call it).

swapping TB guts isn't that hard, i'm trying to think of who did it recently or made a guide of it...

EDIT: and your ECM WILL require tuning... a 3x00 wants a lot different fuel and timing compared to a 2.8...

[2.8 Grand Prix]

Oh by the way,

Will the 2.8s ECM plug into the '00 3x00? The guy I got it from said it should.
It didn't come with the computer.

[2.8 Grand Prix]

Thanks Robert,

I think it is a four speed (1,2,3,D,R,P).

I hope it doesn't need to have the TB taken apart. I know a lot about diesel fuel systems (I have a degree in Diesel Technology), but I don't know much about TBs. I took Auto. Tech. in High School, but mostly all we dealed with was carbs.

Yah he mentioned those too. All I have to do is take them out of the 2.8 and Stick them on the 3x00. Real easy.

How many bolts hold the tranny on to the engine? I hope the 2.8's tranny fits the 3x00.

for coolant temp: the newer motor uses a single temp sensor that has three wires instead of the older setup that uses 2 sensors: 1 with 1 wire and another with 2 wires...

EGR: does it use the same connector? BTW: which EGR did your GP come with? if you have the hood open yet, take a pic of it and we'll know if its a backpressure/EVRV or digital...

the tranny will DEFINITELY bolt up. is it a 3 or 4 speed?

EDIT: might need to swap the guts of the 2.8 TB onto the new one so that the linkages match...

yeah that is one good thing about GM: slow to adapt to new things...

MOST things should plug in directly, the only two things i can think of ATM that won't are EGR and the coolant temp...

[2.8 Grand Prix]

Thanks you guys!

I know I have a lot of support on this website. That means a lot!

I got the engine today. 2000 Chevy Malibu 3x00 w/ 86,000 miles. Intake gasket needs replaced sometime (still holding up ok right now).

I'm amazed at how GM was able to keep all the electrical plugs the same for 12 years. This guy I got the engine from says everything should just "plug 'n play". Makes for an easy engine swap.

I should be getting an engine hoist (cherrypicker) within the next week or so, so I'll keep ya posted on the progress.

[robertisaar]

Like a said above, I am NOT going to pull the sheet over the headlights and give up.
I happen to know of a Saturn (one of the most worthless piles of crap on the planet) that has over 300,000 miles. If a clunky Saturn can do it, a base model '88 Grand Prix with a new engine (86,000 miles) sure as heck can!

hell yes, brother!

W's are meant to last as long as you take care of the simple little things that are required.

How about we don't and say we did. This is still a good car, and I have put too much into her to just call it a day and pull the sheet over the headlights. I think more of this car than just a dented up lawn decoration. I think it has some potential. Maybe not what you or anyone else you know would do, but then I'm not like most people.

seriously, i should avoid this thread... the shop i work at, we get customers comming in all the time with some rust bucket pile of shit burning all kinds of colours of smoke that can barely make it on to the hoist or whatever misfiring and running on 7 out of 8... leaking oil and tranny fluid.... what does he want done? oh he needs a 20K slider Fifth Wheel. hes planning on towing a 18,000lb trailer through the mountains!!

like for real. cars are ALL on a clock and im sorry, but this one has passed. its just not worth saving. its already been to the light for a while now. quit whipping the dead donkey.
