Get ready to replace a few LIM gaskets down the line. ;)

Kidding, good luck with the swap man.

meh, ecotecs are to over rated for me, easier to swap? yes, but i want a torque monster of a car, so V6 is the way to go, plus i know where i can get a blower for it ;)

Good luck finding an M62 blower for the LA1.

And I hate to say it, but for performance...

L61 > LA1

The Ecotec just has a better aftermarket support. Easier to boost and make power.

Don't get me wrong, the LA1 will make awesome power with an LX9 top swap, ported heads, ported UIM & LIM, 62mm throttle body, cam, headers and a tune, but you'll need boost to make +300 HP, and use the 262 five speed trans. The 4T45E trans you'll find behind most LA1s are total weaksauce.

O'rly?

Pics of the said blower. I'm betting money it's an M90 from an L67 motor. Damn n00bs always thinking 90* parts work on 60* motors. :lol2:

Also, Eco swaps are better, simply because of how easy you'll get power from it. As far as boost goes, parts and tuning will be 1000x easier with an L61 motor versus the LA1.

Hell, just lurk on the Ecotec forums, and see the power these motors are capable of. It surpasses the outdated LA1 by far.

i have to agree. my buddy had a 2.2 ecotec in his cavi and was pulling 13's all day and night off of 15 lbs. but, he eventually got rid of his cavi and upgraded to an FD rx-7 with the veilside wide body kit. its meh i guess. lol

Swap in the LNF! If you want to be really orginal and have a torque monster swap in a twin turbo LS7 engine.

yeah would do the LNF but it'd be more work than the V6, and i have a severe thing about being different and original with my car, so ecotec is a no go, and i have easy acess to the 3400 more so than eco's

If you're so gung-ho on doing an LA1 swap, do your homework on what makes these motors tick.

Stock, these motors have NO top end. Past 4300rpms, they just run out of breath. You'll need to increase airflow, IE ported intakes, ported heads, cam, bigger throttle body, etc. Of course, the dreaded LIM leak, due to the crappy plastic ones GM designed, but that should be changed before the swap. The LA1 also runs best with NGK Iridiums, either the actual NGK ones, or the AC Delco plugs.

I'd check out these sites for all performance needs:

LIM = Lower Intake Gasket

Very common with these motors to fail.

Fel-Pro makes the updated metal gaskets.

Sounds like fun. I have seen a few engine swaps in the J-body line. They make evil cars. There is a guy somewhere between here and Toronto who is dropping in a Northstar V8 into a Cavalier. One of the Super Chevy Show's that I have been to I had seen a 572 rear wheel drive 02 Cavalier. Good luck with the swap. Since it is a 60 degree engine are you going to try and adapt a cradle from a pre 94 cavalier or make your own?

I suggest a rebuild/upgrade then. And get an LSD, you'll thank yourself later when you really make more power with the LA1.

im not to worried about it right now, the v6 will be fairly stock for awhile after its put in, other than a few bolt ons

I'd reinforce the chassis as much as possible, you're dropping in a motor that makes a lot more torque than with the LN2. I dyno'd my GA:

167HP

215TQ

Keep that in mind with the LN2's five speed. Also, the 282's gear ratios are better suited to the LA1's powerband.

yeah, itll be getting a k-frame brace and a few other things to take care of that, but it can wait till the engine is sitting in the car, but i need an engine first LOL
