For a highly tuned performance motor - 2.4 or eco?

Lances133 · 07-27-2006, 07:13 PM

I know we've kinda beat around this topic a couple times but I havn't seen an exact answer to this question.

I plan on keeping my cav for a long time so I'm gonna completely build a whole new motor with all performance parts, Yes I'm well aware that this is gonna run me over $10k and I already know it's gonna take me a LONG time. So I need somewhere to begin and that start point is what motor to use? Should I build another 2.4l or do a swap with a 2.2eco? I would want to do the eco, but I plan on going all out and adding a turbo with nitrous, and cryo2. And with that in mind...the eco's aluminum block. That's what worries me about that. With a turbo and n02 in mind should I use the 2.4l motor or do they make more solid blocks for the eco somewhere?

Pick one or the other. When both fully built they both can handle quite a bit of boost. Why not try for the 2.4L eco motor if you wana really play.

he's worried about the aluminum block not being able to handle excessive boosting..

Yes.

What car does the 2.4 eco come out of? Does it have the same mounts as the 2.2?

Cobalt SS (non-Supercharged)

And don't do that, its drive-by wire and you'll be absurdly hard pressed getting it to work.

The eco doesn't like nitrous but likes boost. The Twin Cam doesn't like Turbo, but can handle a Super just fine and takes to nitrous decently.

You really have 6 in one hand and a half dozen in the other. What everyone else will say is pretty much a matter of opinion.

Well, I'm planning on building a new motor from the block up with all performance inards, so unless I can find a stronger Eco block, I should go with the twin cam, correct? In the end of it all and YEARS down the road I plan on having it turbo'd, sc'd, n02'd, and cryo2'd.....alright maybe not supercharged too but def. turbo, n02, and cryo2'd

Yeah, I guess technically the iron block of the 2.4 is stronger. But, when does that start to matter? You really think you're going to be pushing enough power to make an aluminum block explode or warp? Hell, GM Performance has that cavalier they made pushing out 1100-1200 horses on an aluminum block. Granted, its de-stroked to a 2.0, but STILL, you realisitically think you'll be breaking that level, come on...

Like I said and I still stand by:
You have 6 in one hand, a half dozen in the other.

I wouldn't know if I could bust the block or not, I'm just going by what other people have done and I def. don't want that happening to me.

go with the eco if you are thinking about boosting it. Watch how much nitrous you use, though. Would hate to see you dump 10k into a motor and blow it with the wring shot of nos

Lances133 · 07-28-2006, 12:19 PM

Exactly! Which is why I don't know where to begin. I'm definitely gonna have a turbo and n02, I'm not worried about the Cryo2 since it just cools the air.

...so does an intercooler.

And you really shouldn't be blowing off the benefits of cooling. See, that's how you actually would crack a block open, serious overheating from REALLY overstressing the motor.

Granted, the CO2 crap is pretty useless, but cooling = super important.

When I say I'm getting a turbo, it should be understood that I mean with an intercooler too. I would never get a turbo without one.

Just get a damn eco. Frankly Ive yet to see anyone on here talk about doing a motor swap and actually do it.

I know what you mean, I'm quite sick of that too but I'm telling ya straight up I won't be doing this for a loooong time because it's gonna cost me so much money, I'm just asking so I know where to start and what block to buy.
