port and polished cylinder head, and aveo turbo talk

you think there will be any charge pipes for cars that will fit the aveo with only some modification? Like the civic or a GSR, people mod CAI that fit those cars to fit the aveo.

I gotta find the site but there was a company making a turbo kit for the aveo...it ran 7 psi and was only 1995. No one has purchased one to check the quality though.

Nevermind...I found a few reviews and they were all bad. Parts didn't fit etc. And now their site doesn't work.

If you want to turbo it just go to an exhaust shop...they should be able to make you some custom charge pipes for not too much money. And they can weld the joints so you will have stronger joints than if you used silicon couplers.

The problem with that is exhaust shops here done have mandrel benders... which i will definitly need. The shop can do charge pipes they say. So i may just go there for them. I dont know anyone with a mandrel bender. And I dont know if any exhaust shops around here would want to do anything like that anyways. they'd probably have no clue. haha

What I was thinking: I buy a t25 turbo, Blowoff Valve and IC off ebay (maybe a megasquirt also or a different piggy back). Fabricatorx Turbo manifold. Speed shop does the charge pipes and everything else.

Does that sound decent? am I missing anything?

Oh i went to the shop and the guy went to go pick up a crank from a city near by, so im going back tomorrow. They said hed be there tomorrow for sure.

well i ended up going abck to the shop, he quoted me at around $5000. That includes everything, and everything, and a tune on the dyno. He said I can bring my own stuff, but preferred to just have everything be by them (obviously to make more money). But he said the turbo manifold would knock off $600-$800 right there, and If i get the other things I was going to get thatd would knock the price down even more.

He also said they have a no interest payment option too which i thought was cool.

So since this is probably the only shop around me that does this I may go with them, the only bad thing it will probably take three weeks to do. I dont know if thats quick, slow, or average because i dont know how long a custom turbo takes to build. and of course they seem to be really busy.

So you guys want to help me piece together parts? Does the T25 turbo sound good? Remember, Im just gonna buy the bigger things myself. So if you could help me get parts/look for them that would be AWESOME. I plan on getting this done probably January to early Spring.

And I am serious about it too. So you wont be looking for nothing! haha

For $5000 you can buy and make a 2L engine (turbo) that runs CIRCLES around an Aveo motor...

It's easier since there are already forged parts and things like the Kinky manifolds and BMS manifolds

I still stand firm that it's safer and more ideal to run high HP on an NA motor. You don't have to worry about the tune and don't have to worry about part failure (i.e. what happens when the oil filter lets something through, what happens when the tune messes up, what happens when the wastegate gets stuck, etc). Another thing is that you aren't crippled should a system fail. The car would run in limp mode if on an NA build. Finally, it's cheaper... way way cheaper. For $5000 you could buy a 2L, high comp pistons, manifolds, and cams and bust out well over 150 hp... probably closer to 200. The WTCC car isn't modified all that extreme and doesn't use "race gas" so it's not that exotic compared to the other incarnations of the engine. It has manifolds, cams, and a higher compression. The engine is capable of much more but they just aren't pushing it because of their restrictions.

I could get a 2L, but I dont have the knowledge to do an engine swap. I would need a shop to do it. and I dont know how much that would be.
I know the forenza/optra engine is supposed to be easy, but it isnt as easy as just droping a motor in a turning the key. nobody really knows how easy it will be yet. I was considering doing the swap, but figured nobody really knows what to do and how easy it is, the shop would probably charge me a fortune. Thats why i was deciding to first go N/A (but then everyone was saying that almost all the power will be in the rpm range that i cant reach, and low end will be crappy), then deciding to do turbo (where power is available sometimes as low as 2000rpm).

I know the ecm from the forenza is similar to the aveo's. but what does it involve to make it work. I'd also have to be moving components in the engine bay also wouldnt I?

In my opinion if you just used some higher comp pistons...i.e. around 10.5 and a nice set of streetable cams your powerband would be fine. You'd probably get close to 140 at the crank with a pandp'd head to go with the cams and pistons. Just order some pistons and tune it and see what you get. I know the 1.6's in Europe without our vgis make around the same horsepower as ours does with 10.5 comp pistons. So if our head flows that much better...that we make the same power on 9.5 comp then I woud figure the 10.5 pistons alone could get you closer to 120 at the crank without the cams. Add in a port and polish and a nice set of cams and a decent exhaust system and you'd at least see another 20 hp which would put you at around 140-150 I believe at the flywheel.

why not just shave the head to achieve the higher compression? or is there a fear of the valves making contact with the pistons?

For 500$ you could buy 2.0 16V and have 150HP stock..

For 5000$ you can buy whole damn 2L turbo car....

For 1.6 16V (a16DM) with 9.5:1 CR stock, and stock internalls, with turbo you can go up to 200HP... We have I guy here with A16DM in opel corsa and he was getting almost 300HP stock internals... But he broke pistons with lean fuel map...

If you want, on the other hand, like me, change engine (C20XE can be found for pinuts, 500$) it's NA, it's strong, it put out 150HP stock... With some slit changes I get to 172HP NA...

If I had my knowledge than, what I have now, I wouldn't go to engine swap... I would have turboed my A16DM that was stock inside Lanos Sport... Aveo has the same engine...

jidasas · Post by **jidasas** » Fri Nov 09, 2007 2:02 pm

He is right about the turbo making up to 200 horsepower. Which would be the limit of the auto trans in the aveo. And you could detune it to 150 for street driving and run different maps at the track and push close to 170 at the wheels.

are you saying I can boost the aveo engine to 200hp? I wouldnt think thats possible. Heres an article that I read: http://www.daewootech.com/forum/album_p ... pic_id=228

According to that The engine handled 150 without reliablity problems, 200 is a bit more and would expect problems.
If I'm going over about 150tQ, then I would need to upgrade tansmissions (D20).

Is the aveo engine really a A16DM? I thought it was the x16xe?

I hate this debate, I wish everyone would come to one conclusion hahaha
I wanna start piecing this together! haha

I really think I should stick to the aveo engine and not swap unless someone on the board could help me out (I could drive If it only took a few days to swap the engine). So, if nobody within like around 1500 miles from muskegon, michigan can help me with a swap (I could pay also), I'll be doing a turbo, or N/A. But the question still lies... Turbo or N/A

That is 150HP NA!

A have almost 240HP and 300Nm on D16... With no problem at all for 2 years now (40kmiles)...

aveo has the same engine as lanos, and it is A16DM... It has 9.5:1 CR, where opel has X16XE with 10.5:1 CR... So Daewoo version of 1.6 16V with VGIS is better choice for boost...

jidasas · Post by **jidasas** » Fri Nov 09, 2007 6:15 pm

The tranny in the aveo is rated at 200hp and 200 lb/ft. As long as you keep it less than that at the crank then you shouldn't have to change trannys.

hell you get the stuff and we can do the upgrades here. my mom has a 2 car garage, it shouldnt take more than a week end to do the n/a upgrades, but turbo thats a different story.

oh and about the engine beingable to take alot of turbo http://www.daewootech.com/forum/viewtopic.php?t=9514 that kinda settles it, he has 275 hp that was on stock engine for 2 years. thats a hell of a 1.6!
