Tänu Retole sai uuritud natuke ka 8v mootorit. Selgus , et on olemas 8v turbo mootor, mis on opeli disain. Kasutatud neid aga teistel automarkidel nagu Pontiac. Mootor ise selline: 
Tehase tähis siis C20GET. On keegi nende mootoritega kokku puutunud ning kui reaalne on sellist mootorit Eestist leida? Äkki oskab keegi veel öelda kas selle mootori kinnitused on samad mis calibra 8v 85kw mootoril? Sama mootor Kadett'il :

Natuke ingliskeelset juttu selle mootori kohta: The Pontiac Sunbird GT and Pontiac Grand Am GT, came with a 2.0 litre, 8 valve, single overhead cam (SOHC), and a watercooled Turbocharger (Garrett T-25). The engine code is LT3 (C20GET). 2 Versions of this engine are produced still today as the C20XE and the C22XE, by Daewoo. The engine is actually an Opel design but was assembled in Brazil. The bore and stroke are the same (3.386" or 86 MM) which is what you call a "square" engine - the bore and stroke are equal. An "undersquare" engine has a small bore and a long stroke for more low end torque but less high rpm power while an "oversquare" engine has a large bore and a short stroke which allows it to make power at higher rpm but sacrifices low end torque. So I guess the "square" engines do a little of both! -Tony(olzkng@aol.com) The first thing that really impresses you about the engine is the way it accelerates. Its 2.0L overhead cam, turbocharged 4-cyl engine with multiport fuel injection delivers 165 hp without innercooling, which translates to low 15s around 92 mph in the 1/4 mile and 0-60 in about 7 seconds. The garett T25 turbocharger features a water-cooled center bearing for extended life, and it develops a max of 9 pounds of boost at wide-open throttle. An integral knock sensor in the engine's electronics guards against detonation on either reg. or premium fuel, and a block heater is provided for quick warm-ups. The bulletproof cylinder block is still made of cast iron, and the cylinder head is aluminum. Forged low compression pistons with low tension rings are used to stand up against the turbo-charged enviroment, the crank is nodular cast iron along with the connecting rods, but they happily accept the boost. Minor changes over the years of this engine improve sealing and friction characteristics. For example, the valve covers have a new stand-off boss on the lower face that connects the cylinder head when the gasket has been crushed the proper amount for optimum sealing. Engine Code: LT3 Bore x Stroke: 3.386x3.386 (in)/86.0x86.0(mm) Displacement: 121 cid, 2.0L Firing Order: 1-3-4-2 (No.1 cylinder at timing belt end) Rotation: Clockwise Compression ratio: 8.0:1 Intake valve size: 1.69" Exhaust valve size: 1.44" Camshaft duration: 214 degrees at .050" Camshaft lobe centers: 114 degrees 165 hp @ 5600 rpm at 7 psi of boost 175 ft-lbs. of torque @ 4000 rpm |

veel pisut pildimaterjali... nende järgi oleks küll huvi: 
Mootor 'puhtal kujul' 
Ja nagu ka eelmistelt pildidelt Reaperi postituses aru saada, on kütuselatt hoopis teistlaadi... aga alati annab ka C20NE oma sinna kompunnida! 
Pildil on näha aga, et siiber vajab lisa kaableid (andurid, andurid, andurid). Kuid teoreetiline võimalus on kasutada ehk selle mootori juppe C20NE puhul. Alustades siis sisselaske kollest ja kolbidest. Kuid kõik on vaid idee, kui jutuks oleks 8v ülelaadimine. Meeldiv on aga tõdeda, et andurite otsad vaatavad jahutusmahla kanali pealt kenasti vastu (Kuidagi loogilisem asetus ju): 
Kütuselatt ava-vaates: 
...aga infi voolab veel kohale. Tegu siis jah tõepoolest Pontiaci südamega, aga paistab, et käigukast tahaks justkui teisel pool asetseda... aga eks spetsid tea paremini. ------------------- Mõned lisapildid siit: http://www.mindspring.com/~hdethloff/C20GET/ Chevy oopel: 
Ning midagi minu jaoks uut - FX tähisega aju... hmm... 
...praegu kõik...a varsti jälle!
