Wonder how it goes

i bet it'd go better if it had an R32 engine instead of the american one. They never knew how to design an engine. All they do is add cylinders and cu's

i am sure i have seen this on youtube....fair play, its a great effort slapping that badboy into a mk2

Fair play mate!! They've made some absolute ball tearer engines. Just look at the modern Ford GT and the ZR1. They'd both maul most things out of Europe. Cubes or not.

I wouldn't have one myself, but much respect.

I have to disagree with you there, there isn't one style VR6 motor that actually makes any decent power without strapping an enormous turbo onto it, the heads flow so badly and stock for stock they're both pretty pitiful. The americans on the other hand can make a small block 8 put out 3-4 times what a VR6/R32 does and still be NA, I'm pretty sure they've got the motors right.

Yeah Branko has a good point. They've squashed a 6 cylinder engine into a hatch engine bay..so there has to be repercussions. It still goes great, and would go nicely in a mk2 because it's light and will drive it real easy, but at the end of the day nothing that VW produces like the R or VR motors will be in the same league as american engines.

I agree that they don't design them very well (just because I reckon they slap massive things together because ''bigger is better'' in the US) but my my they produce some power for straights...

FWD V8!?!?!?
Hahahahaha...would be awesome for burnouts!

not your average american muscle v8 - 32 valves guys. how many yank engines have 4 valves per cylinder?

impressive. not my cup of tea

from wikipedia - http://en.wikipedia.org/wiki/Northstar_engine_series

The Northstar's design was initiated as a response to the advanced dual overhead cam V8 engines introduced by European and Japanese competitors of Cadillac in the late 1980s. At that time, Cadillac was using the aluminum HT Overhead Valve (OHV) V8 which had been pushed hastily into production after the failure of the V8-6-4 of 1981.

Cadillac was developing new models like the Allanté and updated Eldorado and Seville STS which they hoped would compete against the best from BMW, Mercedes-Benz, Lexus, and Infiniti. They developed a laundry list of items that must be included in these new models, including sophisticated steering, braking, and suspension technologies, which became known as the Northstar System. One key element was a high-tech V8 engine with all of the features and performance of the competitors' offerings.

The "Northstar" V8, as it was then known, was an evolution of the Lotus-designed Chevrolet LT5 all-aluminum DOHC 32-valve V8 used in the Corvette ZR-1. Archrival Ford Motor Company was developing a similar engine at that time as well, and Ford's Modular engine would precede the Northstar into production with its introduction on the 1991 Lincoln Town Car. Both continue in production at 4.6 L of displacement.

Capable of producing 300 hp (224 kW), the Northstar featured a cast aluminum 90° V8 block with 102 mm (4 in) bore spacing split into unitary upper and lower halves. The lower crankcase assembly supported the crankshaft without conventional main bearing caps. An oil manifold plate with an integrated silicon gasket forms the oil gallery under this. A typical oil change used 7.5-8 quarts of oil.

Cast-iron cylinder liners were specified and the forged aluminum pistons included valve clearance, making Northstar a non-interference engine, with bronze pin bushings and free-floating piston pins used.

Cast aluminum cylinder heads were used featuring 4 valves per cylinder. The heads used dual overhead cams which are driven through the "maintenance-free" cam-drive chain case. The cams act directly on hydraulic lifters on the ends of the valves and are fed with a lubrication passage drilled through the cylinder head lengthwise. The intake valves are inclined at 25°, while the exhaust valves are canted to 7° with center-mounted platinum-tipped spark plugs. The cam covers were fabricated from magnesium for light weight.

Eight thermoplastic tubes were used in the induction system, leading to sequential fuel injection. The engine uses a direct ignition system with a single coil per cylinder and no distributor. The PCM controls spark and fuel injection timing as well as the shift points for the new 4T80-E transmission.

One notable feature, advertised at the time, was the fail-safe cooling mode which allowed the engine to continue running for a limited time without any coolant at all. It alternated banks of cylinders, basically "air cooling" the inside of the cylinders, to maintain cool temperatures, allowing a Northstar-equipped car to be driven with no coolant for about 100 mi (161 km) with no damage.

Another unusual feature of some Northstar-equipped cars is a liquid-cooled alternator used on Cadillac's Seville, DeVille, and Eldorado. The liquid-cooling helped prolong the life of the alternator in these electronic-laden models, though GM reverted to a traditional air-cooled setup for 2001 to eliminate potential leak points and extraneous tubing.

All engines of this family share the same Northstar bellhousing pattern.

Later developments included variable valve timing, which can vary intake by up to 40° and the exhaust by up to 50°. This system was devised for the longitudinal LH2 version, and has not, to date, been used on the transverse front wheel drive engines due to packaging considerations.

wheel spin city, nice achievement though.

I would love to know your thoughts on why you think they "don't design them very well"...
