I'll probably sound completely ridiculous here but someone stopped by here a while ago and said his 2.0 OHC non turbo was running near 200 HP?? His engine looked entirely stock except the block was red then he told me the past owner put in some sort of nissan pistons among other engine parts. Does anyone have any idea of what type of set up he's got there?
Not Nissan, but there are subdivisions of GM using the same motor in other countries like Opal. Daewoo also used the 2.0 block but with a DOHC head which is interchangeable.
But.. chances are... there is not enough aftermarket support to make 200whp without turbo or nitrous. Turbo AND nitrous however... that's whats up. ^_^

Red blocks were on the turbo cars. It's possible he used the block and internals which are MUCH stronger than the standard 2.0 SOHC motors and added juice to it.
I used to race cars, now I race myself.
5K PB: 24:50
10K PB: 54:26
I have had three 2.0 sohc turbo motors and none of them had red blocks. Maybe the 1.8 turbo motor has a red block?
I still don't see how and 8:1 compression motor would help him so much. He said it looks stock too, no nitrous.

Hmm, well I am a member over at daewootech.com and some of the guys over there were looking into various piston alternatives for their 2.0L Numbird/Lanos engines. I believe one of them said that they could use the pistons out of an SR20DET because they have the same piston pin size and location. You might want to try searching through some old post over there. Lots of good info that transfers over to the 2.0L OHC engines in the subirds.
Trying to become the most modded out N/A 2nd gen sunbird 4 cylinder on the org with a..... screw that, I'm going turbo!!!
2.Slow OHC I4
Ported cylinder head, intake and exhaust
Relocated IAT with a custom WAI with a 6x9 K&N conical filter
All this, and I still can't go fast.............yet!!
the blocks aren't red stock on any jbody 1.8 or 2.0. He probbly painted it. The cam carrier cover, intake manifold, and charge piping is painted red stock on Turbo 2.0's used from 87-91. The 1.8 turbo';s had the same parts painted black.
If bore diameter is correct, piston rings seal, and the wrist pin diameter and style(press fit, floater etc) matches the con rod, you can put any piston you want. So long as the main stuff matches your good to hook. I've got a couple of old school guys I know that used to build their own pistons back in the 60's when there was no aftermarket for stuff like that. Tough part would be going through all kinds of books trying to find the specs. On a bunch of pistons trying to find which ones would work.

^^^ Assuming the piston reliefs match the valve positions or they're dished enough the pistons don't hit the valves when timed right, that is
thta's a big one. You could fihnd a piston that fits, and then have it be too tall and smack your valves.
Protonus.... what did you think of that link I posted? From the research I have done so far, it looks to be a bolt-on turbo header. I am debating getting one and changing to a T3 flange.

It looks like a 2.0 flange to me too, but the measurements he givs should tell exactly. My concern would be weather htere is hood clearence with that design to even fit a turbo on it. It looks like it would be taler then the cam carrier by a few inches assembled. I prefer from a service and heat stantpoint having my turbo low too. While it would be nice to have a header that is cheap and bolts up the construction on this thing doesn't look that great and it's not equal length. I plan on having a custom one made, there are plenty of companies that could do it.

I can almost guarantee that it won't work. All of the Daewoo's that use either the 2.0L or the 2.2L (the Lanos that he has listed on the site that it supposedly fits uses the 2.0L) utilize a 16V head and the intake and exhaust bolt patterns are different. I actually have a 2.2L Daewoo engine in my shed, and if you want I can take a picture of it for you so you can see how similar they are but not the exact same.

There is a 2.2, 2.0 and a 1.6 DOHC that use the same head pattern and would bolt to our 2.0 blocks. There is also a 1.5, 2.0 and 2.2 8v sohc version. They use our turbo manifolds to boost the 2.2 and the 1.5. The only difference is that they reffer to our engines as a C20get, from opel/vauxhall and barely recognize the that LT3 is the SAME EXACT motor. I've done a little further digging, that manifold will bolt right up. I am going to double check the measurements though for the head flange before I ever say that we can put it on our cars. There are also hood clearnace issues possible like Protonus had said. In my case I'm not worried since I built a custom cowl hood. Then again I also wont be buying one because I am having my own design equal length header crafted.

what about the cam gears, timing belt, and tensioner??? would the DOHC head make enough of a difference to be worth the swap and fabrication?
I plan on living forever... so far so good
Most of the problems are in the engine mounts. The power steering and A/C supposedly get in the way of using our stock engine mount locations.
There are adjustable timing gears and turbo-spec cams available for the opel/vauxhall C20LET which uses the same head as the daewoo. If you don't want that, everything from the daewoo can be used.
Low end tourque should decrease buy power should increase 10-20% depending on what kind of head work you had on the 8v head and what you do to the new head.
