[skeezer]

my dad has one. feels like a clown car to me.

 

[Yaj Yak]

thats exactly why i want one. i fucking love clown cars.

They're very capable rigs. At least compared to the turd H2. Alpha models had the 5.3-liter V8. The I5 is a real shit engine in the heavy H3.

 

[Yaj Yak]

and by real shit you mean gutless?

alphas seem to be holding their value quite a bit... but the 5 bangers can be had for quite a bit less.. ive been reading up on the 5 cylinders and it seems that they are pretty tough lil motors, im thinking a little boost will put some pep in their step...


but no one has done it really...

there are some colorado guys that have thrown turbos at em... but only a few... some good whp #s at not too crazy of boost #s... iirc one colorado on a 3.7 at about 10psi was at 360+ whp...

 

[Yaj Yak]

I will just keep this short and simple.
Truck was dyno'd at 390 RWHP and 430 lbs/ft of Torque.
The dyno was run at 8 psi using a Garrett GT35R turbo.
Some initial pictures.

theres quite a bit of room under there...

 

[Yaj Yak]

i kind of dont believe 390 whp at 8psi... thats nuts.

my 3.8l v6 at 13 psi probably wouldnt be about there... to make that power out of a 3.7 inline 5... mmm.

but if it is true, i think it is an area that these trucks could really expand on... 3-4k$ turbo kit that puts them at almost 400 whp... i really think there is potentially a pretty big market for it... and with it being an inline motor plumbing is relatively easy..

 

[Yaj Yak]

and wtf is up with this dyno graph where 390 whp happens... whatsup dip?

another dyno tid bit.

The addition of the new V-3 Si-Trim centrifugal supercharger will increase crankshaft power from 242 to 340 HP with additional torque up to 307 lb.ft. at 7 PSI. on 91 octane pump gasoline.

imo nooooo way that dude made 390rwhp on 8psi. soemthing went wrong with that dyno... i could see maybe 390 crank maaaaaaaybe but probably not.

Yup. Don't know how much those are, but they also put the 5.3 in 4X4 versions of the COlorado and Canyon, plus the 2wd sport versions of those trucks.

 

[Yaj Yak]

thats true.

if i were to do this id probably honestly use the turbo/injectors/ic off my grand prix- make my grand prix s/c'd headered again...


whats cool is the hummer has a 4l60e in it not some totally obsolete enjinnne so when it grenades its not ilke replacing a tbss trans.

 

[Yaj Yak]

can someone when they get a chance move this into general car.. k thanks.

 

[Yaj Yak]

 

[RICH17]

I like the truck ones with the Humvee style cap on them.

 

[Yaj Yak]

 

[Outlaw]

I approve of this... Would be very interested to see the outcome.

 

[Yaj Yak]

its all sort of a pipe dream, and kind of goofy also because no one has done it really... so itd be interesting to see how the awd parts held up- transfer case/front end/rear end... trans is a 4l60e... so if it needs help its okay to get rebuilt- i havent looked much into the x case or front end or rear end yet... but from what i have read they are pretty stout... 4x4 colorado guys putting 400+ hp through em stock...

im not looking to run 11s or something in the thing- i want it to be peppier than stock and i dont have the money for a 25k$ 5.3 powered alpha h3...

 

[Dasfinc]

I would rock the hell out of a 5.3 powered Alpha H3, Didn't know they ended up offering it in a 'sport' version of the Canyon though, Any info/links on that one Bru?

 

[Bru]

It was called the ZQ8 package.

 

[Yaj Yak]

they make 4 wd & 2wd 5.3 canyons & colorados

another random link for me.

[SinisterSHO]

I've seen a couple of the h3 pickups rolling around, those I kinda like.

 

[GTwolf]

Last winter the dealer I was working at almost always had a hummer in stock. Even it heavy snow it felt like a was driving a subaru on dry pavement.

 

[Yaj Yak]

h3s?

 

[GTwolf]

h3s?

Mostly yeah.

 

[bikrboy128]

the 3.7l I5 is an izuzu engine, and is a turdpile of scrap. i wouldnt buy anything with that engine. my shop works on a fleet of canyons and every one of them had to have the head replaced (not head gasket, the entire head) around 100k miles.
