I have a 99 GA SE with a 2.4 that I'm giving to my son, but thinking about converting it to a 3.4 V6 instead. Anyone do this yet? I know I would have to change trans,harness,pcm,bcm,cv shafts too! anyone have any other input besides just buy one with V6 already installed- 99 paid off long time ago! :molson:

turbo it, theres a way bigger aftermarket for that motor then the 3400. i think for the cost of the swap you can make your 2.4 run what a stock 3400 car would.

Save the money and put it into the 2.4. A 2.4 modded to 3.4 power will still probably have less problems.

Just wondering - Like what is there for that motor than just a turbo? cause I was thinking of buying a wrecked GT (REAR) and sticking it (motor/trans/stuff)in the SE for about $800. Anybody atempt this yet -how about you guru's?

A custom turbo with a tune job? I'd guess 3,000-4,000, depending on where you go.

You could also just slap on a GM supercharger. It says its for 2000 to 2002 2.4's but I have seen people make it work on other 2.4 engines. The kit is only about $2000USD, I'm always surprised that more 2.4TC GA owners don't go this route.:)

I think it's somewhere in the 40-60 HP range, depending on how many PSI you run. I could be totally off, though.

The GM charger takes the LD9 from 150hp to 190hp, this is on 4psi or so, you can easliy bump the power up with a smaller pulley and run about 8psi. also for all you guys with the 2.4 check out www.quad4forums.com it is THE best place for info on the motor.

^Correct.

But, on a 99 you're on your own for fuel mods and tuning tho. The included injectors, 2 bar MAP sensor and PCM reprogram cannot be used. You'll also need a 2000-2001 starter to swap on for clearance.

Might not wanna wait on the supercharger... word is the excess stock of the poor-selling kit has already been destroyed and only a few units remain in the hands of resellers.

That depends on how you feel about your car -if you plan on keeping it because you really like it-then yes

if your thinking about resale numbers- then no! But that's just my opinion!
