next project getting started

[TexasT]

As if I don't have enough to do, haha. We have embarked on the next project. Not a Buick but will be going with a GM 3800 out of a 2000 Pontiac and going into a 1985 Pontiac Fiero. You may notice the blower on top. Seller claimed it came out of a 2000 Pontiac with 87k miles. But who knows as sellers have been known to spin some tall tails. It turns over with a breaker bar and didn't make any disconcerting noises. So cash was exchanged and we loaded her up and brought it home.

Then we got it home.

Two serpentine belts



And a blower.

Nice I’ve always wanted to do that swap!

[TexasT]

My son is pretty stoked. It came with a trans and accessories and he sez he can get the mounts and such to make it work. Also came with the harness and computer so an hp tuners subscription is on the horizon to do some tuning when we get it in there. I guess it is a 4t65e but ill have to do some studying up to see.

Should be a fun ride.

Will be watching this closely. A friend has a 3800 SC out of an Olds and a Fiero sitting in his garage for a few years.His original plan was a small block 400 but I think I persuaded him the 3800 is way easier.
 He was moaning about some guy that made a great conversion kit but quit?.

[TexasT]

There is a site called pernocky Fiero or something my son spoke of. And he thinks there are already mounts to use and some vids on the YouTube on how to do it. He is pretty excited.

This is going to be a must watch thread Rich!

[TexasT]

I just hope this engine is decent. I let him check it out. Kind of discussed what I would look at on the way but let him do the forensics and negotiation. He has to learn and it is his money he spent. I just supplied the trailer, straps and tow vehicle to go get it.

Should be a fun one. But as anyone who knows me this will take some time. Still have the 4l60e half assembled and the front end stuff to out back together. It has been cold and rainy(in know, not that cold for you northern fellows) but it is suppose to be fun. And cold hands and fingers aren't fun to me. I'd rather be swimming in sweat.

The car is an 85 Fiero he bought last summer. Him and his buddy went and got it so I didn't get to look it over first. He fooled with the brakes and decided the engine is no good. So we searched up the sc 3800 and away we go.

If there's a drop in kit for it...then that'll make it easy. There was a guy that showed up at the track a couple years back with a Fiero that sounded like it had a SBC in it. I got busy with a TR owners car and never got a chance to talk to the gent as I was really interested in it. He never showed up again...so I never did get a look at it or ask questions.

Original v6s used a similar ECM IIRC

[Scoobum]

Rich, those 3.8's are bullet proof. The girlfriend has one in her Camaro winter beater with 400,000 km's on it...equates to about 250,000 miles. Starts in any temperature. Check the EGR...they tend to crack. I couldn't find a good one at the wreckers. Had to go with a new one.

[TexasT]

I am studying up on this hp tuners so we will be able to program the ecm and such. Also want to be able to turn off the vats on two other vehicles we have. Got to reading on the hptuners forum and the vids on YouTube. They seem to go so fast I have to stop and replay it several times to get where he is going. Watching one where he takes a rise, makes a log and then pulls up he logg and a table and "smoothes" it. Is this just for the speed density I think. And what is the segment swap? Seems to be for the transmission when going from one to another and maybe for going to a flex fuel. Anyone have some insight on what all is entailed in doing this? Thanks

You can smooth any of the 2d/3d tables.
Segment swap is more for the LS 411/P01 stuff. Segment swaps are for transmission stuff mostly, say 4l60 to 4l80.
FWIW L67 (supercharged 3800) tuning is pretty straight forward. If it's stock you'll force open loop and tune the maf curve for fueling, followed but pulling a pile of timing to keep knock retard under control.
If you get stuck I might be able to help you out - hell if you have internet in the workspace I could remotely help you tune it.

That thing is going to fly!    There was a guy with a northstar engine in a Fiero here.
