It doesnt come directly from a vw van. Its a mishmash of different vag parts and some made by porsche. _________________ 1980 924 Turbo

From all I've heard/read on it, I've it boiled down to this -
Only the same basic block was used in other vehicles, and it was reworked by Porsche (larger crank journals, different crankshaft, rods, pistons, etc. (so engine bearings from the others won't fit)).
Some of those other vehicles that may have used the same block are VW LT van, Audi 100, AMC (Gremlin, Pacer, postal jeep), some tractor... _________________ "..it's made in Germany. You know the Germans always make good stuff."

These are all definitely known to have used the same basic block design. I've not encountered the Pacer in my research, but that doesn't mean it wasn't on the list too. But the AMC Spirit and AMC Concorde also used the same 2.0L block, as well as AMC's joint venture with Renault which resulted in the Alliance. There may have been a couple of other Renault models that used it too, although I haven't been able to 100% confirm. During the 87-88 time frame that the Alliance was being built, there were 2 or 3 other Renaults built on the same platform as the Alliance that were between 1.8 and 2.0 litres that very well could have used the same basic power plant.
An interesting piece of info: the VW LT van was a diesel. Given the super-high compression required by diesel combustion, you can understand why the block is such a solid piece...and an excellent platform for high performance development.

hrm, I have read otherwise.
From what I understand, not only is the K-jet tronic identical (in all but configuration) to a like yeared vw van, it's the bottom end and the same block as most VW vans.
The block its based on has been configured as a 1.6 1.7 1.8l, 1.8Turbo, 2.0L. it can be used with a huge number of heads, crossflows, 16V 8V solid or hydraulic lifters.... and those are just stock options. I've had a lot of cars with these blocks, a 86 wolfsburgh jetta with a 1.8 solid lifter. a brazilian vw fox aka lupo or polo with a 1.8l hydraulic lifter motor. I daily drive a 1.7l vw rabbit with solid lifters. They are great motors in stock configuration, and they can make a lot of power for a tiny 4-banger. If you want to learn more, you can check out VW books at the local library.
The block in the 924 IS indeed a audi100 block, found in the 100-400 and the early audi and VW foxes and vans.... however like someone else said, the porsche engine is a diffirent animal with a custom head, and entirely reworked internals. _________________ All work and no speeding makes jack a dull boy. |

1. VW LT 2.0 engine was petrol engine, rated at 75hp. I've torn them apart like 7 or 8 because they usually have cranks that are in very good condition.
2. It doesn't have ANY 16v head that could be fit to that block.
3. Audi engine has different pistons, head (smaller intake valves and no provisions for injectors). Van engine has pistons with very large dish and only 7:1 CR. _________________ '83 924 2.6 16v Turbo, 470hp

I'm interested to hear more about the audi 100 head.
I have been looking at improving the intake port shape on my 924 N/A, and am struggling to work out how to add material.
Is the intake port smaller on the audi 100 head? or just the valve. _________________ 1981 924 N/A |

First, Top Gear is for entertainment only, anything said by those three petrol heads should be taken with a huge grain of salt. The only one I might believe when discussion turns to specific mechanical details would be Capt. Slow. Not to say they don't make good points, but you need to know when they are trying to be serious or when they are just going for a laugh (at Richard's expense)
If you watch the 1500 pound Porsche Challenge episode (available on YouTube I believe), you'll notice the 924 is the only one to complete everything without a single issue. If the short one hadn't screwed the pooch and actually bothered to put the 944 suspension under the 924 he'd have finished much higher in the standings instead of spending 750 pounds on some tyres and springs to come in last behind the 6-cylinder 928.
The fact that the tall monkey can't brake stand an automatic shows just how ill-informed a driver he can be and why they sent Capt Slow to be trained by Jackie Stewart to drive quickly.
Before anyone asks, a brake stand is holding the brake with one foot, while you hammer the gas with the other foot. You use the torque converter in the automatic to place a load on the engine and when you release the brake you'll either spin the wheels or launch fairly hard. Drag racers use this quite often to launch their cars while in the engine's power curve. Turbocharged cars benefit greatly from brake stands by generating boost from the load placed on the engine. On the 928, even with 6 cylinders he probably could have gotten a proper set of "11's" _________________ Stefan

my cent, stefan the 928 has a 5.0 Liter V 8 engine which is made from two 944 engine/s/heads.
And from what i know the 924 NA engine has the same block as the VW LT light trucks. In the trucks vw used a diffrent head with a caburettor set-up. It developed 90 PS.
We put some light there......all together.  _________________ NA 924 - april/1977- 4-speed-audi gearbox.

Not so.
However, I think Stefan was joking about the poor condition of the 928 in the show. . .it was not hitting on all cylinders and eventually died from cooling issues as I recall. _________________ Toofah King Bad

As Rasta said, NOT SO! It's the other way 'round...a 944 is ½ the engine of a 928. The 928 was developed long before the 944, the 944 inherited the 928 head. And the early 928 was not a 5.0L, although I'm not certain which variety they used in that particular episode.
And YES, the 2.0L block was also used in the DIESEL VW LT van. So in that sense, the 924 has a "truck" motor. Although as others have pointed out, the head, intake, injection, pistons, crank, etc. were all unique to the 924. _________________ erstwhile owner of just about every 924 variant ever made |
