Keep in mind that back in 1990, that 4 banger made 180hp n/a at time when other most others needed a turbo to make the same or less power. In 91, the W41 made 190hp and was years ahead of the ITR.
The bean counters really screwed the engine over from cost cutting, especially concerning the head gasket and ignition housing plastic.
Still, 180hp and a 5 speed in a 2600lb car made for a high 14sec car that got well over 30mpg.
I had a GTZ too. I also had a Calais S auto, a Calais I-Series, a GA GT, and an Achieva SCX, all 5 speed cars.

My dad had a Calais S for about 6 months...then my mom hit her annual deer...hard!I had a GTZ too. I also had a Calais S auto, a Calais I-Series, a GA GT, and an Achieva SCX, all 5 speed cars.
Damn, you loved them 4-banger GMs, lol.
I had friends who had actual ITRs and swapped Civics at the time. What really sucked was how little mods were available for that damned car. That's OK. I'd just switch to my old LX notch and handle what my Beretta couldn't.
Now that sounds really good. If I didn't know it was a 4-cylinder I'd swear I was listening to a healthy V8.Here's an extremely old vid of the Achieva idling with the blueprinted W41 engine. the cams were factory stock, notice the lumpy idle...for a 4 banger.
Im surprised the olds supreme indy pace car wasn't mentioned. It had a turbo Quad4 in it that made 250hp back in 1988.
Olds/GM had a chance to be really innovative but they really let everyone down. A 250hp ANYTHING in 1988 was amazing. Iirc Corvettes only had around 250hp until the early 90s
i did, lol. before that, i had a 69 barracuda notchback when i was 18-21. i wanted something a little different.
the Calais S auto was stock. the I-series had a 2.5" exhaust, homemade inner fender CAI, and the chip from a W41 Calais (higher redline, slightly different timing and fuel). best 1/8mile in that car was a 9.70 @ 74mph on a street tire and on DRs it ran a 9.50 with a slipping clutch. the GTZ was stock. the GA GT was rebuilt with 11.5:1 pistons, forged rods, 226/.410 lift cams, titanium retainers, and an extremely rare Olds race chip from a scca world challenge car. had a lightweight flywheel and a spec 6 puck clutch. it pulled hard to 8k and was a lot of fun to drive on the street. the Achieva was gutted and had a cage. it was the autocross car. it had a leftover blueprinted W41 from the firehawk series a long time ago. it also had a 1 5/8" to 1 3/4" step header. didnt take it to the strip either but it was fast enough to outrun ls1/auto camaros and modded new edge mustangs on the days id drive it to work. it weighed 2620lbs with the cage and a full tank of gas.
not long after, i found a hell of a deal on a 97 cobra vert and bought it. i own that car to this day and still daily it with 83k.

Damn...... Im gonna have to go search that up lol
That sounded nice for a 4 banger.
All I ended up doing to my GTZ was a custom-piped exhaust with no cats. I couldn't even find a basic high-flow filter. Shocked the shit out of my buddies with their VTECs though, lol.
