This all started because Kyle (-alero-) crys all the time about his poor LA1 motor and why o why he didn't get an LD9.
Buck up boy, want a LD9, go get one
In fact, there is one around here for less then $4000 and it's a stick. I would buy it, but I don't have that much cash flow.
All 3 motors have pontental, and a lot of it. All 3 motors can take power adders very easy and make crazy power. I've heard of a 3100 Malibu that is running 13's with a cam and some head work, not drastic head work either.
Earlier versions of the LA1 found thier way into the Ferrio, and some of which were kitted to look like a Lamborghini. Not saying they are as fast as one, but it's still has to be a respectable motor for that.
Plus the cost difference in aftermarket parts for the 2.4, 2.2 are far cheaper than the 3400's, why? Because the 4 banger parts are ava just about everywhere, the 3400 parts, you have to hunt for them.
The real plus to the 2.4 motor, is that it's orgianlly an Oldsmobile power plant, and the last of the manfactor specific motors to be mass produced. It's not the exact motor, but it shares a lot of the same parts as the 2.3 HO that was in the 91 Olds 442.
Not to call out Ion, but he's right now, running 14.8 or so in the 1/4 mile with a s/c. Yes he probably could turn the boost up and get it faster, but I'm running 14.5 all motor. and boost for boost, what are the Devner boys running? low 13's at 5,000 feet above sea level. Probably would be high to mid 12's at sea level.
My point is, all are good motors. Don't like what you have, grow balls and trade it in, but quit crying about it if you don't
