C20GET

[Laagvlieger]

Door Oenatje zijn post in algemeen bullshit ben ik geintereseerd geraakt in de C20GET motor uit de states.
Dump hier alle info die je kan vinden!

Picz:










Blok zit eind 80 en begin 90er jaren in de volgende modellen:

"This is in 1986 Pontiac Grand AM Turbo also

Possibly in Buick Skyhawk pre 1988

Sunbird GT ~1986-1991"

[Laagvlieger]

The engine is a C20GET.... which is a factory 8V turbo engine Pontiac and Chevrolet used here in north america during the late eighties.

From factory it had no intercooler and used a T25 to stuff 7psi into the cylinders which featured Mahle forged 8:1 compression pistons.

It was rated at 165hp and 175 lbft of torque from factory.

Worldwide, there are a lot of people modifying the 2.0 "J series" engine in both 8v and 16v format. It has been available over the years in capacities from 1.6L to 2.4L, in carburated, injected and turbocharged formats. The engine has been used by the majority of GM owned companies around the world.
The 2.0L 8v turbocharged varient has the engine code C20GET, internal code is LT3. The 16v turbocharged version is the C20LET.
A "blueprinted" stock engine with slightly raised boost and good quality fuel will make ~200hp. There are a number of engines both in the US and UK making close to 300hp. Some in northen europe have made ~400hp. There are a number of 16v versions making over 500hp. My own engine should achieve ~350hp with its current spec.
There is a great deal of tuning parts available for these engines if you know where to look. Anything from throttle bodies, H-beam rods, steel cranks, dry sump systems, even replacement aluminium blocks are available.
These engines are commanly turbocharged in Brazil so there are decent cast manifolds available for it to replace the stock T25 with a T3 or T3/TO4 hybrid with an external wastegate.

I hope this has been of some use...

Heej interesante motor!!!!

Ik ga kijken of daar wat over te vinden is!

C20GET op Google

Nog wat fotootjes

Hmz, beetje data betr. de techniek zou wel handig wezen.
Opzich kun je een SEH nemen en b.v. een Lexmaul aanpassen, met de gasklep naar voren.
Smeed een spruitstuk, en een passende Mitsubishi turbo pakken b.v. van een Saab 9000/900.
Dan kom je ook in de buurt.

Ik las dat ie ook nog in de Ascona geleverd is, als enige wagen in europa, Ik kan dit echter nergens bevestigd vinden...

www.opelnews.de | Drucksache | 8v turbo...
Nun, es gibt/gab auch nen Ascona 8V Turbo und in Amerika gabs Serie ganze 8V Turbos, die C20GET, unter anderem im Pontiac Sunfire. ...

Waarom een SEH ?

[GSi Twente]

Ivm de zuigers, nokkenas...
Laatst met Corsaboy van het opel-forum heel wat van verteld gekregen.
Die is nu bezig met een compressor eraan het opbouwen.

[adriaan]

een seh heeft andere zuigers voor een HOGERE compressie dus je hebt er niets aan

[GSi Twente]

Geen idee wat voor zuigers hij er dan in heeft, hij had iig een SEH blok.

[pluggie]

Wat is dat dan joh ?
Vette vondst !
Ik mis even wat. En loop achter.

[Laagvlieger]

Ik ben nog op zoek naar het motormanagementsysteem.
Welk systeem zit erop?

Dan nog type zuigers..... Zijn speciale laag compressie zuigers.
Mogen best iets meer compressie hebben en dan WEL een IC monteren.

[Sounddragon]

Volgens mij gaan ze je erg wazig aankijken bij de dealert als je voor een setje C20GET zuigers komt

Ik vind dit wel een blok voor jouw Station Soundjuh!

...the major difference between the GET and the LZ, NE ect. is valve angle...
...if you do build a SOHC i highly suggest using my stainless header flange kit and have someone weld up a custom fit header for your application, kit includes 1/2" stailess head flanges, 1/2" stainless T3 flange, and 1/4" EGR block off.
the EGR system is run off the third exhaust port and i recomend using moroso's block filler to completely eliminate it.
some people have found that the larger Pontiac Fierro throtlebody will mount to the manifold, but i'm not sure from what year, tom knows.
PISTONS, make sure you use the GET pistons, Mahli offers a set. they drop the compression by 0.5:1. they're dished and .5:1 may noy be alot but that little bit can make a world of difference.
rods and crank are the same for the turbo and non-turbo.
look into KENT CAMS the offer cam, valve springs, ect. for the motor and you will atleast need the GET's bee hive type valve springs if not the Kent Cams double spring. they also offer a set of uprated cam followers that are very much need for big turbo build ups.
WHOEVER BUYS THE C20GET I HAVE FOR SALE GETS ALL THIS STUFF!!!!!!, accept the Kent stuff thanks

Klephoek zou anders zijn. Dus cilinderkop is toch anders.....

[Sounddragon]

Ik ook, maar ik wacht Rellie's Compressor experimentje even af
Vind ik eigenlijk nog veel leuker...

En ik denk dat zo'n blok compleet ernstig veel pleuro's moet opbrengen, even afgezien van het feit dat ik hem dan waarschijnlijk uit de states zou moeten halen op de een of andere manier, en met alle daaraan verbonden problemen...

[edit] is die Laag me weer net voor , maar die knakker heeft er gewoon eentje te koop dus

En die klephoek beantwoordt dus ook mijn vraag waarom dat kleppendeksel zo raar hoog is gemaakt denk ik [/edit]

2.0 Turbo (VIN M) (engine code: C20GET):
HP: 165@5600 RPM
TQ: 160@2800 RPM
Compression ratio: 8.0:1
Bore x Stroke: 3.38 x 3.38
Firing order: 1342
Intake valve size: 1.69"
Exhaust valve size: 1.44"
Cam: elevation = intake – exhaust: 0.2409 – 0.2409 for 1989
0.2625 – 0.2625 for 1990

<b>2.0 to 2.0 turbo:</b>
This is probably the most often asked question ever when it comes to the 2.0 and so I guess it
makes since to put it on here
To change from a 2.0 to a 2.0 turbo is a lot of work and the easiest way to do it is just to swap
the motors over, cause the only things the two engines share are the block, crankshaft and the
connecting rods. But if for whatever reason you decide to keep your block in your car you need
to swap pistons cause the turbo pistons are forged and the 2.0 NA's are not, you need the turbo
head cause of the compression ratio change, (8.8:1 NA - 8.0:1 turbo) for those of you who think
its stupid to lower compression and gain power with a turbo.....trust me it works. You will also
need all the wiring, ECM, throttle cable, oil pan, intake, exhaust, turbo, down pipe, fuel pump
(unless your car was originally MPFI then its better than the turbo pump) and basically
everything attached to the head except the block, get a turbo head gasket when you get a new
one, obviously, lol and all the air box crap too if you wanna go stock. Transmission change is
also a good idea if it’s a 5 speed, see the "Transmission" section.

Is dat koppel en vermogen nou in een andere eenheid ????

Vind het erg weinig eigenlijk... die 165 paardjes kan nog... maar 160 Nm ???? geloof ik geen bips van

[Laagvlieger]

Koppel is LBFt, das andere eenheid jha.
Zegt mij ook nix eigenlij. Zla keer even omrekenfactor zoeken.

[AstraMarc]

lbft to Nm vermenigvuldigen met 1.3558

175*1.3558=237.265Nm

lbft is pound-feet.

[Sounddragon]

237 Nm klinkt al een stuk aannemelijker

Upje vanwege nieuwe interesse...
En wat foto's die ik via Google vond.

Nog een mooi stuk tekst van http://forums.sportcompactcarweb.com.

If your going to go with a J-Body project why not go real old school and pick a car that is:

1) extreemly cheap to buy
2) extreemly robust
3) relatively light
4) Came factory with a turbo 4cyl engine

The answer is the 1987 to 1991 Pontiac Sunbird GT or Pontiac Grand Am SE turbo.

The engine is an Opel design... it's like the Chevy 350... runs forever and hard to kill... it's been mass produced all over the world under Opel/Holden/Vauxhall/Pontiac/Passport/Chevrolet/Daewoo/Buick in pretty much every country in the world.

The engine has been around since the early eighties and is still the block of choice for the high end Vauxhall/Opel vehicles such as the Astra VXR

The iron block 2.0L turbo "C20GET" was an 8V engine that featured Mahle forged 8:1 compression pistons.

The factory engine only made 165hp and 175lb ft of torque but that was due to the fact that GM was too cheap to install an intercooler and GM had to tune the ECU to give it a really rich A/F in order to keep the engine safe with the stock 7psi of boost.

Drop in an intercooler and bump the stock T25 turbo to 13psi and you nearly double those numbers power wise.

Sure this iron block 2.0L turbo isn't as popular as the aluminum ecotec in north america but it has a huge aftermarket following in the UK and Europe where it was found in most of the perfomance orientated Opel/Vauxhall vehicles.

Varients of this engine have the potential for an easy 350whp... in fact you can puchase an "off the shelf" C20LET (16V version of the engine found in North america) with 750ps (740 horsepower)from a company in Germany ( www.vmax.de )

There are kits that allow the 16V versions to rev up into the 10K or 12K RPM range depending on your budget.

There are a number of Sunbirds running around with 400+hp that are practically stock...intercooler... extra injectors...bleed valve for the stock 2bar MAP sensor.... race fuel and a few upgrades to the stock transmission and you have a car that pulls into the high 10's or low 11's with slicks.

These old J-Body cars can easily be stripped down into the 2200lb range and there are a number of upgrades available for the engine, tranny and suspension through north american companies like Mantapart and Opel components drop right in so you can get forged connecting rods and pistons here in north america through Import Performance Parts (division of Flatlander racing)

If it were my project.... I'd pick up an 89 Sunbird GT turbo for a couple hundred dollars, drop in an aftermarket clutch, upgrade the MAP to a GM Cyclone 3bar sensor, increase the injector size, drop in a larger T28, drop in a GM Cyclone Walboro fuel pump and crank the boost to 25psi.

For a couple grand you will have a car that will show most modified imports the rear tail lights.

ik heb er ook wat over gevonden...


astrs mk 2 forum


schijnt in de states en Canada een andere motorcode te zijn ofzo....
heb het nog niet echt aandachtig gelezen

ik weet niet of dit een c20get is

Heej het topic was er nog wel dus!
