Has anybody done or attempted to swap an 2.0 turbo ecotech instead of the G54B...was wondering, and if so, how difficult was the swap...also wondering if the ecotech could fit stock 5 speed, thanks for the help.
Forged motor, weisco pistons ,3" exhaust, garret 60 cold/ 96 hot turbo, 950/ 1800 injectors , 52mm tb, maft, meth kit.

It won't bolt up to our 5 speed. But, just get a whole solstice drivetrain, ecu, harness. Neither engine or transmission are large.

I don't think it would be practical to swap in an ecotech.

Seems affordable a bunch of takeout combos on ebay. Should fit easy. Gm offers standalone ecu provisions if needed. Not easy but can be done.

if the ecotec 2.0 winds out past 7000 rpm, u wouldn't want a starion box behind it
the solstic 5spd is supposed to be very similar to the(bulky) R154
I'd think swaps would be common by now, if they were 'all that'

It would be as difficult as any other modern 4 cylinder turbo swap like the Ford Ecoboost or Dodge SRT-4. You'll need the ECM & BCM to run it.

It's not common in our sqc community because, well our cars are uncommon. But ecotecs are swapped plenty and often. It's a great engine.

plenty & often? well why r they doing such a great job keeping "plenty" off the net ?
For eg... rwd rollas r swap hoares. Never seen a single one. Multiple samples of everything else tho

seems like a whole mess of unneccesary crap needed, just for what should be a 'simple' rwd swap
http://www.s10forum....warning-494496/

performance-wise they offer nothing over say a sr20, 4g63, RZ, etc ....offered from like 24 years ago
ecotec turbo package appears to target quick spool= robust midrange. Plug it in, use it like that. Fine
Ok if upgradeing from weak n.a. powerplant..... but when the glove$$$$ come off, then what?

and GM is the king of confusion. Enough reason to keep me away
a buddy took 3 tries to get replacement pistons for his turbo'd 5.3 avalanche LS swap. No error on his part
who needs that crap in their life ? This sport is supposed to be fun right  :huh:

You sound a little biased against GM.

But anyway, I've seen them swapped in miatas, kit cars, triumphs,mg's, and a few other platforms. Most of them I've seen in person at autox events in California, and Texas now as well. Because internet lore doesn't flood information doesn't mean it isn't popular. The Sr, 4g, nd rz are great engines as well although a bit primitive. Seen plenty of those swaps too. LFX is getting popular now-a-days.

The link you referenced is 6 years old.

I'm sorry your buddy went through that. I don't paint pictures with one brush though.

Non-GM vehicles use them as well like the SlingShot.

as a kid, cut my teeth on what was arguably GM's worst ever ehgine..... chevy vega 2.3 4yl.
Never had one single problem, ever. They must've 'liked me' back
Buick 3.8 smoothness & torque, caused my 1st swap. Modding the 3.8/4.1, naturally led to a Grand National
Later sucked into the revised, more refined 3800... I still have a L67 supercharged version. GM bias? .... yah

Doesn't matter how old the links r, the swap related pitfalls r real

Internet still give u a broad cross-section imo. Ecotec suits a rwd rolla perfectly, yet ....count 'em.
A few samples of the bulkier, heavier LS powered and more compact buick 3800
SR20 rolla swap for example, outnumber the GMs, more than 100 to 1, ez. Point: "popular" is relative

....and 'primitive' means nothing when a powerplant can provide hassle-free, all-around top shelf performance

You must have neer had the "Honor" of working in the Cadillac HT4100!  My daily is an '01 GTP with 220K miles on it.  There is a lot of value in a durable and hassle free engine.  If only with they had built an aluminum 3800.

at least the HT4100 caddy had "hi-tech" pretense. Vega 2.4 was a 'primitive' ohc 4cyl trying to get an aluminium cylinder/block to work.
My skewed experience due to having the later revised steel liner block. Did ok several trips up & down the east coast, but the V6 swapped station wagon smoothness + acceleration put the 4cyl to rest.

oh man.... that would've reeaally been nice! Cheap, plentiful, compact, rugged, decent power/big potential...
Guess the ecotec possibly gives u all that? :D
I recall renting an olds delta 88 way back. It pushed u in the seat with 5 adults on board, while the front tires scrambled for traction!
In the whisper quiet cabin, the performance actually became a topic of conversation (surprisingly as I was the only 'car-guy').
While waiting for the gang outside a restaurant, I decided to take a peak at this GM V8 magic underhood. Couldn't belive it was a 3800
A few 'ringers' must've slipped out the factory. I have an old car stereo review magazine showcasing a full Nakamichi system install in an olds cutlass Ciera. Final paragraph of the "car stereo review", he raved over the astonishing acceleration of the car... over the stereo!
Trust me, nevermind the hp/tq rating.... something was 'not right' with some of those old 3800s. I honestly believed that delta 88 would've ran my stock GN hard! Sharp minds at GM.

getting off topic, but I think the 3.8 supercharged from a grand prix gtp would be cool. My GTP wasn't the fastest thing out there, but it was quick for a car that size. Very responsive. Daily drove it for years. Has a good aftermarket base and community support.
I know somebody in this group did one, not sure about how it went..
It's different and reliable.
My 2 cents..
88 Quest, 13.1 on street tires. w/a few mods
89 Quest, street car, w/porno red cloth int.
87 Quest, two parts cars

My daily is an '01 GP GTP with full Borla and a tune and it completely woke up the engine/transmision.
