custom turbo kit

[andrewsvt03]

i'm just curious why no one has tried making their own turbo kit, i was looking in my engine bay yesterday and i think with an adapter plate a turbo could be bolted up to the stock exhaust manifold.
honda guys have been doing it for a long time, and it would be cheap. i still have my aveo(even tho i'll probably be getting a new car soon) but its driving me nuts that my car is stock. i think with and adapter plate i could bolt up a used t25 turbo off a second gen eclipse, which would give great response on our car(d16 honda guys say it feels like a powerful N/A motor) of course you'd need custom piping, intercooler, bigger injectors and engine management, but i think you could have yourself a solid streetable turbo kit for under 2 grand easy. honda guys do it all the time, why shouldnt we?
i'm sure it would only take 5, maybe 7 psi max with stock internals, but it would be a huge difference.

you know i keep reading that our engine cant handle boost and the tranny will break at 200hp, but i havent seen anyone prove it.
i would be willing to bet there isnt a person on this board with more then 130hp, and thats being optimistic
you know when people started to modify hondas all the v8 guys said it was pointless, that it was a waste of money(alot still do) but people proved them wrong.
we cant just sit around putting fart cans and honda short ram intakes on our cars if we ever want the aveo to become a half respected car in the inport(or automotive community in general)
i already realized a long time ago that intakes, exhausts just dont cut it if you really want your aveo to be anything more than slow. i'm not trying to rain on anyones parade here, but you guys know its the truth.

95% of the car people i know think its pointless to modify an aveo, they all say "get a dsm or a honda, and leave the aveo to do what it was meant to do, get you from point a to point b" the only way we will ever get more aftermarket support is by building up our cars and showing up at shows and races, and proving these cars are worth building.
sorry if i am rambling, but sometimes i get desperate seeing that performance wise, our cars are stangnent, we still dont have a true, cold air kit out there yet much less a header that we can buy without going thru the hassle of ordering from out of the country, then hopeing it will fit

i think i am gonna start picking up the parts i need to make my own turbo kit, and once i start putting it together i'll post pctures along the way of my progress. and if i blow the tranny at 200hp then at least we'll really know how much power in can handle. you gotta start somewhere right?

im getting ready to start building a turbo kit in the next few months. I'm going to be using a lot of parts from 360dynamics, including their turbo exhaust manifold that has the T25 plate. And you can get those turbos for next to nothing from ebay or a junkyard since they're everywhere.

And so far about the tranny breaking at 200hp, i believe that's for atx

i agree with what you said andrew and I would have my car hooked up if wasnt for the fact i dont technically own the car since my parents are paying for it so i can get to college and back......but once the warranties on these cars start to run out i think alot of people will be hooking up their custom kits....it just hard with it being a new car and most people dont want to start messing up a perfectly new car when they are still paying for it. and yes it is the auto that can only handle 200....the manual could in theory hold whatever power you could make with a turbo and more if you reinforce parts of it. As for me personally I am waiting for other people to leap into this stuff first so i can learn from the mistakes since I can't do much for power right now. Id really love to see someone do the 2.0L swap and turbo that, but hell if it isnt done when my warranty is up that will def be a project i will be doing. i wish i could just find a 2.0L for the price of 300 dollars that one person on this forum did

[y2daniel1981]

only 9,000 miles left on my warranty! I've had my car less then a year

i just sold a t25 turbo, because i didn't think it would fit, but now i'm going to get another one and build my own kit. andrew your like the jerry mcguire of this forum, its good to hear someone going against the grain of what everyone around them are saying. your totally right in everything you said and i have said it in a couple of posts that we all need to start banding together and making things happen or nothing is ever going to happen.
As far as using the stock manifold, i have never heard of that, what would it take to get a turbo to fit into it? besides the plate i mean.

[AveoSam]

i dont even know what my warranty is but i will probably have to wait until im a good way thru the amount time i have to go to college...which is gay but atleast my dad will let me work on improving handling and braking

I did the research with daewootech.com and went with the D16 header for the turbo header. I bought a cheapiy off ebay for like $20 with the T3 flange already welded on. The bear was you have to ream out all the bolts to get them to line up with the Aveo head. Plus the exhaust ports are pretty off too. To get the full impact of the header you have to port match the head. My header is sitting at work on the lathe waiting to have the 02 sensor hole drilled and a bung welded on. In my opinion, this is way too much work for 5psi. Your looking at 140-150hp. I only have 1800 miles on the car so I'm working at a snails pace. Plus I have no friggin idea what to do about an ECU. As it stands now, I'm tempted to wait till I can afford forged internals and go higher on the boost to make it worth it. I don't want to grenade my motor just so I'll be the first kid on the block with boost. But, to each his own.
Oh yeah, as for the stock header, you can use it but you would need to have a shop fab you up a plate that would have the stock header patern on top and turbo pattern on the bottom. Or you could just cut the plate off the stock header and weld up a turbo flange.

as far as engine management, i think i'll use an apexi afc ll, i had one on my turbo eclipse and they work great, i know i wont be as good as stand alone but for a cheap low boost kit i think i will do the job. from what it look like, you would just need an adaptor plate to bolt up a t25... i know of a few shop around here that do intercooler piping, and i can pick up a used intercooler for a couple hundred bucks and make some mounting flanges... the t25 in a internal wastegate turbo so no custom exhaust manifold... bigger injectors... i think 360 dynamics sells some right? or if i find a car that has bigger injectors that will fit i'll use those cause they will be cheaper. aveohotrod, you are right, it will probably only put out 140-150hp, but even that will be a huge difference. and you are only a set of pistons away from higher boost and higher numbers:)

[andrewsvt03]

oh and as far as the tranny, if it can handle more then 200 that awesome, are there and s for it? if not there is probably a phantom limited slip... as far as the clutch are there any stronger then stock replacements? i really want to do this, i know it can be done.
half the fun will be pulling up next to all my friends that said it was pointless to mod this car and beat them, or at least give them a good run for their money lol.

[AveoSam]

u could get custom shafts like the gm project aveo and u can get a limited slip for this tranny its in the tranny section

[Brian5475E]

you can get a clutch overseas. remeber the 1.6 ecotec in europe is the same engine as ours. Spec the x16xe

I love the idea of a turbo, but why couldn't you just throw a bottle on it and call it done? First off you can buy it in the U.S. and you can get alot more power for alot cheaper. I was thinking about getting a turbo, but then i realized that half the things i would need would have to come from other countries and its going to cost a butt load. Thats just my opinion, I'm still thinking of going with a turbo just for the fact that it would be awesome, and and i personally love turbos.

But why not just put nitrous on it?

[AveoSam]

y not just swap in a bigger motor......

[teague]

nitrous is still the cheapest horsepower i know of, unless you can find a bigger motor for under $300

My Optra 5 allready has a 2.0L ( U20SED ) engine..... but I was going to save the factory engine and leave it stock.

I picked up a Forenza 2.0L with 9K miles for about $250 USD and had it shipped to my friend in Montana..... I then drove down(12hrs).... picked up the engine and drove back.

;D
