From 2.4 to 3.8

[Sportalero]

This webpage has been around for a while on the J-Body site, so this may be old news to some of you, but i'm pretty sure it might be of interest to some newbies. Yes, it's a Cavalier, but a 2.4 is a 2.4, of course, of course. And I put it in the "General Performance" forum because i'm pretty sure this mod is "not limited" to just the 2.4s :thumbsup:

it's all in french or something, but it looks like a nice job. If I were going to do that, I'd work the 3800 out a little to get more than the 280 HP.... but it looks like a nice clean install. I wish I could read about it.

click on the flashing "english version here" button at the top of the page

[Aleromaster]

see anything is possible with money

[Oldsmopimp]

Yea, I clicked the english version and took a peek. Looks like they did a good job. One of us needs to find the time and $ to do that to an alero. My fav pic was in the, "mod" section.....where they r droppin the motor in and there is a budwieser sittin on the fender. awesome.

After seeing this and what the cost was (although I bet that guy had a good hookup on stuff) it makes me wonder if I dont wanna just save the money up to swap to a bigger engine with a charger already on it instead of saving up for a turbo alone?

Can anyone tell me what 5300 Canadian is in US coinage?

[Redog]

I like. Nice sleeper :thumbsup:

about 3200 3300$...i think

I'd like to know what all he did to get the computer working correctly.

[wy3134]

I agree, had to be some serious reprogramming to get everything to work together.

[Sportalero]

I e-mailed the guy and this is the response i got:

Hi. We connected all the GTP sensors to the PCM except the fuel tank pressure sensor (Cavaliers don't have it), and all works great. We also had to connect the brake light with the TCC (Torque Converter Clutch), because my car was manual and has no switch for the TCC release.

Not quite sure if this is the info you guys wanted but if you want to get ahold of him, his address is :

z24sc@yahoo.ca


He was pretty good at giving me a quick response :)

[wy3134]

That shocks me....hmm I might ask a mechanic I know if something similar can be done to my car...that would be a hella deal and be cheaper than some $6000 level 4 turbo or supercharger....granted I could find that good of a deal on an engine without having to ship it across country :blink:

[3.4Alero]

That makes NO SENSE. If I am reading it right, he said that he just connected all the GTP stuff into his Cavy computer. His cavy was a manual, and the GTP is an automatic, so how the hell does that work?

[overdrive75]

^^It doesn't work. A manual J-body computer doesn't have any of the automatic transmission stuff calibrated, so the car wouldn't shift or anything. Plus they are two completely different computers. No just from a calibration stand point, but from a hardware stand point as well.

Just think about this for a minute. Can you run a V-6 off of an I-4 calibration. I think not.

[3.4Alero]

That's what I was saying. There's more to this than what he has told you.

[Fast Eddie]

the way I read that they used the GTP PCM, since they used the rest of the front clip, and just omitted the fuel cell press. sensor, since there isn't one on the cav and "hotwired" the brake lights.

[Redog]

He had to get a new PCM. That's the way I would have gone. He just doesn't know about it, because the car would not run right at all if it wasn't done

[Sportalero]

^^That's what i think. I believe taking pictures and supplying the brews for the guys in the shop is the only role he played in this whole project. We'd probably have to contact the shop directly to get all the info. Anybody near the Quebec area :rolleyes:

[3.4Alero]

Eddie, good point. I guess that could work. As I reread it, it does look like that was what he may have been trying to say.

[Sportalero]

The Dirt:

Hi, Robert. Im the guy that did the swap. The pcm wire harness, tranny, and
fuel pump are all from the GTP. If more questions, call at 1 450 375 9399

thanks

I don't know why this is always such a hot topic. Over on the 3400 forum a guy wanted to put a 3800 in his car because he wants to start taking it to the track a lot more? I hope he means drag strip...

As if the alero wasnt front heavy enough with the 3400 engine, a 3800 in an n-body and a supercharger mounted on top would make for a terribly unbalanced car, and I wouldnt want to have to drive it in anything but a straight line...

"Balance" people... cmon!

If you want a drag car, go buy a camaro or mustang :rolleyes:

First off, this topic is not like the other topics "Would it be a good idea" or "How much would it cost?" This topic, plain and simple, is for the benefit of those who want to see it. If you noticed, no one in this topic has really focused on cost or performance. Nearly ALL post have been about technical aspect of doing the swap.
If you're too narrow-minded to notice that, then don't bother posting here.

[Final-Reality]

How is thinking about either the practicality, usefulness or consequences of such a swap narrow minded? :unsure:

A rear-drive alero would be both more usefull (as far as drag racing and cornering balance is concerned) and more interesting from a show-car standpoint.
