Hi everyone, my name is Erfinder and I'm second in charge on the Daewootech.com forum.

I found this link through Tim so I thought I'd sign up and clear up a few technical issues with regards to the powertrain.

I probably won't be on this forum all that much as I have devoted most of my time to the Daewootech.com forum and to the company called 360Dynamics which Tim has mentioned.

I'm a Canadian owner of a Chevrolet Optra 5 which is the Reno in the USA.

I just want to assure you guys that the engines in these cars are capable of some very serious horsepower.

The two primary engines 2.0L and 1.6L are both manufactured in Port Melbourn Australia by Holden.

Here is the GM global link....

http://www.gm.com/company/corp_info/global...s/australia.htm

These engines have been in production for many many years ( 1981 ??? ) and they
have been the primary drivetrain of most Opel/Holden vehicles for the last 25 years.

The Lanos is the primary choice for a Taxi in Poland because the engines are kill proof if you know when to do your service.... my friend Tom (owner of 360Dynamics has about 330,000 km on his 1.6L engine and it's still going strong)

The Achilles heal of these cars has allways been the timing belt..... I would suggest changing it at 50,000 miles to be sure you don't have a problem.

I personally will be running some higher horsepower via a turbo kit so I'm going to change my belt every 40,000 miles.

Hopefully one day we will get a high performance timing belt but at the moment the only thing available is the stock belt.

My primary project is a buildup of a 2.2L Daewoo engine ( nearly identical to the 2.0L )

It will eventually become a 2.4L with Ductile iron sleeves (wet install with Hardblok in the lower half )

My goal is to beat the European fellow that managed 625hp from his 2.0L block.

I'd love to make 650hp but it's going to take quite a while to get the engine together.

Here is some info.....

Lanos (Canada) --> 1.5L SOHC --> ENGINE CODE A15SMS
Lanos (USA) --> 1.6L DOHC --> A16DMS

Nubira (Canada/USA) --> 2.0L DOHC --> T20SED

Leganza (Canada/USA) --> 2.2L DOHC --> T22SED

Chev Optra, Optra 5 --> 2.0L DOHC --> U20SED
Suzuki Forneza, Reno --> 2.0L DOHC---> U20SED

Pontiac Sunbird GT Turbo --> 2.0L SOHC TURBO --> C20GET
Pontiac Grand Am Turbo --> 2.0L SOHC Turbo --> C20GET

Pontiac Lemans --> 2.0L SOHC --> C20LZ

Opel/Holden/Vauxhall Astra/Kadette --> 2.0L DOHC--> C20XE, X20XE, X20SED, C20NE, C20LET (turbo 16V)

The list goes on and on.... there are piles of cars out there.

Here is an interesting fact.... in Europe they have a super heavy duty AWD 6spd transmission that will bolt up onto the U20SED with very little work.

Most guys use these in their high horsepower C20LET engines because they are kill proof.... they convert them from AWD to FWD with a simple kit.

In Europe the C20LET is very popular for modifying.... most are capable of 350whp with next to zero modifications (totally stock)

All they have to do is crank up the boost by adjusting the turbo waistegate actuator.

As well it's not uncommon for these engines to hit 10,000 RPM in Europe.

There are kits available to make this happen but they are very expensive and only available from Europe (germany I think)

Needless to say these engines have never come to america in such large numbers before so it won't be long before performance parts become available.

Some of the current European Opel engines have the same block but there are quite a few differences in the top end (cylinder head, fuel management )

In Europe they have a 16V racing head developed by Cosworth.... this head is the best one to get.... but ours aren't too bad either.

In Europe they tuned the 1.6L DOHC for 150hp and found zero problems with reliability.

The only reason we don't see this kind of power is because of emissions.

I'm helping Tom at 360Dynamics develop all kinds of products (I don't own any part of his company... he is the sole owner) and I'm hoping to get the first prototype kit on my Optra in the new year.

I should also quickly mention the transmissions.

In Europe the Getrag F16 and F20 have been used for 25 years or more and our cars have a slightly updated version called the D16 and D20.

The 6spd is called an F28 and there is also an F18 that will fit.

The F16 in Tom's (360dynamics) project car was capable of handling his 2.0L turbo engine up to about 190hp (at the wheels) and 240lbft of torque.

Given he was gentle with it going through corners he wasn't abusing it.

Now he's dropped in an F20 tranny he imported from Sweden and he loves the longer gear ratios that allow him to get to about 65mph on the 1-2 shift.

I can't remember what he ran at the local 1/4mile track.... I think it was about 11.7 second.

Anyways..... I'm sure this info looks a little scrambled but I'm trying to type as fast as I can so that I can get back to answering emails from other guys.

I'm pretty open to questions.... so feel free to drop me a line on the Daewootech forum.

Hey,
the heavy duty transmission thats easyily swapable to the U20SED engine. Aboutt how much HP do you think it can handle? and how much would it cost to buy and ship over here? just woundering

thanks,
Dan

Hmmm.... I don't know exactly but probably more than 400WHP.

Cost on getting it to north america is probably going to run atleast $1000 USD or more.... depends on the mileage on the engine and where you are shipping it from.

I could see a low mileage F28 going for $1000 and shipping would be about $500??

These are just guesses.... it's Hard to say.... Tom (360 Dynamics) would know better than me... he shipped an F20 over from Sweden.

I personally wouldn't bother with the 6spd unless I was planning for more than 300WHp.... the F20/D20 is a fairly decent transmission.

I was just woundering, maybe for future refrence :D Maybe one day.

Greetings from finland.

The facts that the f28 is kill proof is a fact in one way, but the awd isn´t really very strong. it is true that they have taken great power from the c20let engine, and in finland or germany, all the c20let engines came with the awd. And they were in Opel Vectra, and calibra chassis. the Most powerful c20let engine has 670hp and 790nm in torque, or thats the strongest engine that i know.

To the gearbox. The Fourwheeldrive activates with oil presure, when the tires in front or rear has even 2 millimetres different size the 4wd will get broken. and it is really expensive to repair, im talkin about aprox 6000dollars repair.

:angry: 670hp 790nm ???

Oh well.... I guess I have a new goal :angry:

I just don't know if an F28 (with a 2wd conversion) will handle that much power.

I've had a tranmission specialist looking into the new 6spd F40 found in the new Vectra to see how well it's made.

Unfortunatly they are so new he's been unable to find one except for at a dealership.

I heard one fellow boasting that his F28 with straight cut gears is rated for 900BHP but I really have to wonder if the internal shafts are good for that much power.

My tranny specialist in the UK said he figures he can put an F28 together that will handle atleast 450bhp but he said that 600hp + is questionable.

Alternatively there are some automatics which can handle the power without too much problem but I really wanted to be able to make the car work on an autocross track as well as the drag strip.

I have to wonder about the whole "6000 dollars to repair" .... I can get a completely rebuild F28 for half that price ( shot peened internals, case polishing, blueprinting and carefull assembly with "perfect" tolerances ) and that includes a Quaife LSD B)

Are the Daewoo 2.0L/Optra 2.0L/Cobalt 2.0L all the same Motor? All have the DOHC 16V heads? I know the C20GET and alike have the 3.38 x 3.38 Bore and stroke. Are these other 2.0L the same?

Will their DOHC 16 Cylinder heads be able to bolt on (with slight modification) to the LT3 (C20GET) Block?

Yes, and yes, except for the Cobalt engine, which is a different family and will not fit/
