Alright, I'll definitly do that!
I'll let you know when I get it. I keep meaning to call the guy to buy it, but I have been super busy. I'm gonna try to buy it this week.
Then it would have to be a Friday or Saturday that Id be able to drive to detroit. But yeah I'll post on this thread to let you know when I get it, or you could give me your email.

For once we can actually figure out if the lanos intake mani will fit the aveo!

oh and a quick question....

With CAI, full exhaust with a header, Port and polished cylinder head & intake manifold, and Cams... Do you think I'd hit the 150 HP mark with out high compression pistons?

That would save me a boat load of money. I dont want to mess with replacing all the internals, cause the engine can handle about 160hp reliably, anything over stuff starts breaking. (so ive heard)

Or do you think the engine would run smoother with High compression pistons instead of cams? i know it all depends on how mild the cam profiles are.

yeah a saturday would be great, i work mon-fri so saturday would be tbe best

Are you referring to 150whp? or 150hp at the crank?

150 hp at the crank I would say might be possible with those mods, but not 150whp. Depends how agressive you are with the cams, P&P and intake manifold. The more agressive it is, the more power you stand to make up top, but you might loose out on low end torque. Also to make high power with NA motors, ideally you want to rev as high as possible. The stock 6500rpm redline doesn't leave much room for this

At least with higher compression pistons you would see more torque and hp everywhere across the whole powerband. I don't know exactly whats available for your motor, but maybe you could get even higher compression pistons, provided you are willing to always run the highest octane fuel.

150 at the crank i was looking for.

Well i was wanting low end torque also, so it sounds like I should get a more mild cam, and the pistons to make a more even powerband? Also, If I get a really aggressive cam, My idle will probably be rough... not something I'm looking for. With 10.5:1 compression I doubt I would need premium fuel (92), I would probably be able to run 89? i dont know, Id have to do the mods and find out eh?

But yeah I was looking for a relatively smooth power throughout the rpm range.

Since you paid about $3,000 for your turbo set-up I just wonder If I should do that to get the 150hp, I was planning on spending about $3000 for parts and installation (having a shop do it).

Hardly... To get to 150HP from 105HP, I think is almost impossible without forced induction... To do it N/A, your engine must be optimized for 8000, or 9000rpm... And you will loose low and mid torque... Honda civic VTI managed it with 1.6 16V, but with VTEC and 8500rpm... Daewoo engines with stock internalls are not that good... A16DM engine has nice low CR, and it begs for forced induction... It would be much cheaper, and you would see some real figures...

I'm going N/A old school way, but it is rough, and hard, and low in HP figures... I have 150HP stock 2.0 16V engine (C20XE), and with complete headworks, 11:1 CR, opened exhaust, remaped, I see ONLY 172HP on dyno-brake... I hoped for 185HP at least, but nothing... Probably I would come to 185-200HP on crank, but much afford and very expansive...

I could have gone the forced induction way, but, I could get greedy so I didn't...

I just called a speed shop in town ( www.allspeedperformance.com ) And they said their custom turbo setups run around $4500 (im assuming installed - hopefully). I'm gonna stop in tomorrow to talk with them more and they can take a look at what I have and everything.

With that price do you think It would be better off just going turbo, or N/A?

N/A = $3000-$3500
Turbo = ~$4500

overall it sounds like people favor turbo setups more for their smooth power band, where as n/a power is in the high rpms. Also it sounds questionable if I'll be able to get 150hp going n/a, where its basically guarenteed if i go turbo.

for a good reliable 150 hp, id go turbo. but im in no way an expert so dont take my word as gold (please)

thats what I'm thinking too. the only thing that wouldnt be reliable is if i get too much power and start breaking things

I think turbo is more dangerous than N/A on our engines. You can increase the CR and keep the fuel system stock and gain massive hp. Add cams and intake/exhaust and you'll have a beast. You could even run higher octane fuel and let the ECU adjust timing for even greater power.

For the cost of a safe and reliable turbo system, you could have an easy 150hp all motor...

xstevex · Post by **xstevex** » Thu Nov 08, 2007 12:25 am

ahhh the debate. which way to goooo?

I was talking fabricatorx on the aveoclub.net board and he can help me come up with a kit and build me some stuff, so that would cut the cost down compared to going to that shop i posted about.

but what should I do?
Whats gonna be safer, and a better power band?

Talk to Audacity...he really understands these 1.6 motors quite well. If he says you can get 150 and a decent powerband I'd believe him.

And with the N/A you won't be waiting for a turbo to spool...wait not getting into this argument because it depends on what you want...neither is inherently better...they are just different routes. As far as reliability either can be just as reliable when done the right way.

so I should just go with my initial plan, and do an non-aspirated, non turbo build up like audacity said to get a more reliable engine?

But the thing about the N/A is people are saying that all the power is way up in the rpm, a lot of the time past the 6500 rpm redline. with the turbo, the turbo can spool at about 2500 rpm.

Audacity:
When you mean more dangerous, how much more dangerous do you mean? Isnt it the reliablity and a safe turbo'd engine all in the tune (which I would be getting by a professional)?

As of right now, with fabricatorx willing to build me stuff for the turbo, I can get either for just about the same price I believe.

4500$ IS WAY TO EXPANSIVE!!!! To get NA 150HP, you would probably need more than 5 grand... But the mediate turbo setup for up to 200HP, 3 grand is more than enough... If you want more like 300+HP, then you would need more money...

You need some starting turbo kits found on ebay for 500$, and few pipes, piggyback or stand alone ECU for another 1000$ tops. For 3k$ you could do it for daily driver without any problems...

xstevex · Post by **xstevex** » Thu Nov 08, 2007 1:10 pm

4500 is complete custom though. but fabricatorx would be a lot cheaper than the shop, he's done some headers for the forenza and starting some aveo headers aswell, so he already know whats up.

And to get even 200hp I'd need to beef up my internals. And thats hard to find, any ideas to get beefy internals?
The only reason I said 150hp was to keep the internals stock.

I could get like ARP bolts and stuff like that but what about the other things i would need?

but I'm going to talk to the shop here in a few, I'll come back and tell you what they say.
