Nope, it'* the DOHC. Cool car though

Some may call me crazy but I like the domestic 3.4 DOHC and Ecotec'*. Many reasons, long story...too lazy to go into detail. I just like 'em.

Yes they were good motors - a few years back, my dad bought a '91 Sunbird SE 3.1 V6 coupe with 384,000km (240k mi)... it leaked oil BAD, as in one drop every few seconds, few as in 5 seconds. That was fixed, it really needed a complete brake job, tires, shocks/struts, and a rocker cover gasket, to name a few things. Purchased for $300... the previous owner drove it from Hamilton to Woodbridge, Ontario (borders Toronto to the north) and back for nine years to achieve that mileage.

We racked up almost 40,000km (25k mi) in not very long - a year or two, and sold it to my neighbour for $1000. It'* just a shorter trip car now, a grocery getter kinda thing. 425,000km (265k mi) and running like a champ. Rust is there, but not bad

But overall, these motors were pretty good - not all owners had good experiences with them, however. No match for the 3800

edit: oh, and the guy who had the Sunbird - he now has a 2000ish Grand Prix GT

Interesting, most of the Bonnys I've seen in the junkyard (Standard Auto Wreckers, for those of you in the Toronto area) have less than 300,000km - not even 200,000 miles. I'm guessing tranny failure, as the body seems okay. The engines tend to be a bit dirty, but otherwise intact.On the other hand, I did see a Sunbird sedan (1991ish) with pretty much brand new KYB shocks in the rear...

They are generally ver reliable engines, however, MANY V6'* have intake proplems, or problems with the top of the engine. My friend sold his 97 Monte carlo cause the 2k taurus was "more reliable".. Yeah we'll see about that..

I know I'm late and don't know a whole lot about the DOHC multi-valve variable timing thing, I have driven all of the Shelby-Dodge 2.2 turbos. The TI SOHC, the TII SOHC, the TIV SOHC, and the TIII DOHC. Of all of the SOHC'* the fastest bone stock could run 0-60 in right around 6.8-7 flat. Even the TIV SOHC with the VNT (Variable Nozzle Turbo) which had no turbo lag could only manage a 0-60 in a Dodge Shadow in like 6.8 seconds.
Then if you got in the much larger Dodge Spirit R/T'* and Daytona IROC R/T'* with the TIII DOHC you could rocket from 0-60 in right around 6 seconds flat. $100 (that'* right, one hundred dollars) in mods and you would be in the 5 second range.
Top speed the TI SOHC could manage around 115-125 depending on the car it was in. The TII SOHC could run around 130-135. The TIV SOHC was just as powerful as the TII, but it'* turbo was too small for the higher speeds so it was only able to hit around 125-130.
Then when you got the TIII DOHC you would have a car easily capable of breaking 150 bone stock. One of the big Nascar drivers took a 1993 Dodge Daytona IROC R/T to Arizona Speedway because he couldn't find a good straightway for his. Coming down the back stretch he was radared at 173 mph bouncing off the rev-limiter. This was a bone stock car. Quite impressive, so watch out for the 1991-92 Dodge Spirit R/T (looks like a Spirit ES, but with red stripe on the lower mouldings along with a small trunk spoiler) and the Daytona 1992-93 Daytona IROC R/T (can be noted by the emblem on the front fender that looks like a European side marker and the 16" 5-spoke 'Ninja" wheels).


Anyhow, that'* my $.02.
Stylez

You have to take more care of a DOHC engine. constant oilchanges (good oil so it doesnt clog trying toget to the cams). you do have extra timming chains that will need to be replaced 250,000km?
