I need some info on the sunfire 20e engine ( build around 89 / 90 ) (american car).

It's a 2.0 liter 8v turbo engine. I own a 20seh engine which basically is the same engine only without turbo.

I need to know what the part number is of the pistons or where I could find more information regarding this engine.
I have a cr of 10:1 and the 20e engine has 8.5:1 which would be perfect.

The problem is that I live in the Netherlands and the 20e engine is only sold in the USA so finding information is very hard.

Any information would be appreciated.

The 89-90 weren't sunfires..they were sunbird

even the turbo ones are slow, just use the turbo parts to make a HMT honda

Sorry my fault, it's ofcourse a sunbird.

Slow? how much Hp does an HMT honda push? I know the 2.0 8v turbo engine can be pushed to 260 Hp without any problems (stock internals ).

If you take this engine and put a 16v head on it, it can easily be pushed to 325 Hp. The 16v head is also widely available here.

Edit:
Offcourse you need to change the injection system (More fuel) and a bigger intercooler is necessary but for the rest it's pretty straight forward.

i see 1 possible problem with putting the 16v head on a 8v block. piston valve reliefs. u might need the 16v pistons aswell. lets hope that a shorter rods is the reason for the lower CR

A stock 1990 sunbird weighs approx. 2450lbs. A stock 1990 crx weighs approx. 1950lbs. That is about 500 more pounds then a civic/crx. Those horsepower readings are to the flywheel whats the loss to the wheels 10% or 20% something like that? So much more factors that you need to include in then just horsepower, you could have a lot of horsepower and no torque and go nowhere, no traction, stuff like that factors in more then just oh i have 1000 horsepower but im on stock suspension, stock tires and stock driveshafts and ---- like that.

1990 crx hf weighs 1950.. si is 2200 or so

If I were you I would just turbo it until you get the pistons.
Make a nice mani and turbo that thing.
My mom used to have a sunbird...but it was an auto...

Offcourse it's not only the HP number that counts but a statement like sohcrxsi stating that all sunbirds are slow is also BS.

In the Netherlands we have the following engines:

C20NE - 2.0 8v 115Hp
20SEH - 2.0 8v 130Hp
C20XE - 2.0 16v 156 Hp
C20LET - 2.0 16v turbo 204Hp

With my car 900Kg's rear wheel drive and the 20seh engine I have never lost from a CRX or CIVIC even VTec's.

With my other car 1.8 8v 115Hp front wheel drive I have also never lost from a CRX or CIVIC including VTEC.

This is not to start a fight or whatever. It's just my opinion. Now I would like to continue in a normal matter.

Further with the thread.
Putting the 16v head on the 8v engine requires pistons with valve reliefs but in that case I could use the pistons from the 16v engine.

I could use the 16v turbo pistons in my engine block but since they are designed for 16 valves they have valve reliefs which I don't need. Therefore I am lookingg fir the 2.0 8v turbo pistons. But this engine unfortunately has only been sold in the US.

those pistons were made by mahle. so contacting them would be the easiets way of getting a set. as for the EFI stuf GM was kind and equiped your car with a turbo computer here in the states, ahhhh
