Dude. Speaking as someone who has done a turbo install. Let me warn you on what you are about to undertake. Firstly thee is ALWAYS something to go wrong. The moment you say to yourself "Naw, that's not gonna happen to me because I'm only gonna..." you have just lost. I am now sitting and hating my car and what I did to it. The project as far as I am concenred is now officially a complete disaster. The car drives like shit. I don't even want to get into all the problems I'm having. Let me just tell you what's best for these cars and what's possible.
1) These cars were never ever intended to be turbocharged and as such their set-up makes installation a nightmare. A front mount intercooler is ixtremely hard to figure out. The radiator is so wide that a pipe isn't able to get past it. I would recommend you try to use a smaller radiator...sounds odd? Not really...it just needs to be narower by a few inches so the pipes can pass it. Bear in mind that this will cause slightly more lag because the pies to the intake are obviously longer.
2) Mounting the turbo is another nightmare. The a/c compressor, oil filter, radiator fan and a few a/c pipes are in the way of ANY turbo you use. ANY direction you turn the turbo it results in somehting being in the way. I had to shave the edges of my radiator fan shrowd, modify the oil filter (I curently use a smaller Toyota filter) and had to have my a/c piping re-routed.
3) Your stock injectors are too small. You need at least 19lb injectors to get the job done right. Along wiht other little fuel supply helpers like a more powerful fuel pump and a boost dependent fuel pressure regulator.

There are other things that will be an issue for you. But dude, I am getting so depressed right now I just don't evenw ant to talk about it. If you got any questions just ask..I'll be happy to help.

But let me just say this one thing. If you were to ask me if you should do it, I would tell you NO. If you can find it the better option would be to use a bigger engine from the Nubira. It's not a cheap procedure, but it is far more reliable. If I had that money again I would sure as hell opt for the engine swap (that option was open to me at the time and I failed to take it)

Sure, it could be said that others have been successful at this. But ask..how much money did they spend and how much head-ache did they go through? Man..if you want a fast car...save up and buy one. I must now admit that for all it's worth Daewoos are great cars. But they were never intended to be anything but basic, efficient transportation.

I'll be removing my turbo in a few weeks (once I get the money together to have it done and the car brought back to spec). This is the biggest mistake I have made in my entire automotive life. Bar none. Can't wait to have it behind me.

hmm

this is serious stuff i take it.. well before i do anything i am going to have people who know about doing this type of stuff help me out. like the guys at DnK motor sports, they are cool, they told me they would help me out so.... we'll see about that

keep you guys informed

WooHoo wrote: i dont see a blow off valve being to usful but i dont really know

if you have a turbo car with no blowoff valve, then what that would do is, when the throttle body closes the air that is still in your piping woudl come out of your turbo, which is very bad, a blow off valve lets the charged air out. as for a intercooler no you dont need a intercooler which cools the HOT charged air that enters your engine, but if you had one it would be like a 20-30 hp gain. since ur in the junk yard, try and find a 2nd gen eclipse turbo, t-25 isnt a bad turbo fully spooled by 3k rpm's and can boost 16psi safely. cuz thats what im boostin in my eclipse all day long :twisted: if you need more help on what you should get just ask me, k thanks.

i found a really nice shape turbo a few days ago but i dont know what model it is

Actually that's a chrysler conquest. I know someone that knows everything about these and I'll ask him. I think it's a T-25, but don't quote me.

You HAVE to know what you're getting yourself into before you take on a project like this. You must do a large amount of research before hand, so nothing comes up and surprises you. Please don't think that getting a turbo, intercooler, turbo manifold, and a few guages is going to do it. It's waaaaay more complicated than that. Look online and find out what other people purchased and what they bought for their custom turbo. Turbing any car runs on the same principle. Some are just more expense than others, some need more supplies, but you need to make sure of a few things. The way the fuel is delivered, there's enough clearance for everthing, and make sure the pressure isn't too high for the engine. There's a few other things, but I don't want to make this longer than it needs to be. Most of the time spent is testing and tuning. And if you're not patient or don't have a spare car, then forget turboing all together. It could take months to get it tuned right. And even after is up and running, it's more high maintenance than an N/A car.

You should try and find yourself a Pontiac LeMans GSI in the wrecking yard.... the seats alone are worth looking for.

The seats in the LeMans sports coupe (GSI) were Recaro sport seats made for GM and yes they fit our Lanos!!! ( Since the Pontiac LeMans = Daewoo Lanos )

I haven't managed to get my hands on a cheap set in decent condition yet but I've seen them in a LeMans....very good support....very comfortable and it looks like they just bolt right into our stock location.

You should run an intercooler no matter what the boost level is to help save your engine from detonation and it should help with the power levels a little.

You don't really need a blow off valve at 8 psi (although it sounds cool when vented to the atmosphere)

I'm not saying don't get one....they do help the keep the turbo spooled and running smoothly during shifts.... I'm just saying they aren't absolutely necissary ( I plan on using one on my 2.0L turbo but I plan to push 5psi to 8psi on the road and 15psi to 18psi on the track )

By the way WooHoo I haven't located any decent RRFPR's yet (rising rate fuel pressure regulator) but I will keep looking in my spare time.

Maybe someone else knows a good source for rising rate regulators out there in the north west USA area.

Right now I'm disconnecting wiring and hardware connections from my 2.0L turbo....just took a brake to eat....hope to be pulling it out of the Sunbird in the next day or two.....possibly today if I don't run into any further problems.

It's too bad your having so much trouble with the install...it would have been nice to have someone document a 1.6L turbo install on this forum.

I'm surprised that you didn't have room....sure seems like there's lots of space.

Did you ever try looking for a radiator that is twice as thick but only takes up half the front area? (in width)

I know a few local shops up here in Canada that will make a custom radiator to what ever specifications you want (if you have the money).

I wasn't sure if the four stock injectors would be up to the task.... I guess you could allways add a 5th injector just after the throttle body....fairly easy to hook up...can be used with a separate controler which allows you to "tune" the car on a dyno.

Erfinder, the space problem... he installed the intercooler in the engine bay, not a front mounted intercooler... like u said is bad he had all those problems, i still dont understand how his mechanic didnt found the problem...
