has any one ever done a porsche 8v conversion into a vag car???? i was looking at a 944 the otherday 4 cyl 8 valve and it looks just like an old k-jet, and it looked about the same size only its 2.5 littres not 1.8 was just wondering if anyone has ever done a conversion like this? how hard it would be or even if its possible at all? as i would quite like to go nuts and put one in a mk2! cheers joe
I saw somebody ask this on another forum some time ago and the problems highlighted were that the porsche shares the gearbox bellhousing pattern with the audi 5 pots, these were mounted longitudinally which means you need to do some serious body mods to fit it this way if you plan on keeping it fwd as the engine will start way before the bumper! If you converted it to rwd you will still have to make a lot of one off bits
hmmmm so its viable then!!!! its mad how cheap the engines are! there like 200 quid with good history myself and the rest of the cable gtie engineering crew will be paying great interest in this cheers guys
i had a audi coupe 2.3 20v and the block sits right up against the grille, no room at all... and as said above it sits longitudally althought it was front wheel drive, sounded fantastic tho....
its approx 5 inchs longer, ill measure in the morn, but even the headgasket out of the 2.0l 8v 924 looks like something from a bus...
You're not far wrong! remember the 924 engine IS after all taken from the VW LT van... the later 944 engines, despite being 4 bangers are huge, mainly down to the balance shafts.
Right, its approx 5 inchs longer........even looking at the 924 2.0, its 600mm long incl cam pulley....thats pretty long. Dont forget also that the 2.5 has 100mm pistons so it all adds up. Another feature of these engines is the angle there canted over at, pickup would have to be changed, dipstick, and Im not sure but i think the head could flood itself with oil if it was straightened up as the big returns are on left side. This could put pressure on things like valve stem seals, etc.... heres the turbo below, but from working on them, all the engines sit at this angle. Dont you just love these type drawings
I dont know Chris, I cant think at the minute...928 is the only one thats immediate in my mind? but that was out after? not well up on 928s at all. (dont mention chopping and engines to me or ill never get the porker on the road )
I expect the angle is to get a lower bonnet line. The 2.5L 8v produces less hp than an ABF on Kjet, although more torque. Is it really worth it? If you're going to do it, you probably want to start with the 2.5 16v (rare) or the 3.0, but they'll cost a bit more than a 2.5 8v.
These are details of the Audi 100 based 924 2.0L motor. The 2.5L and 3.0L engines are a completely different motor derived from the 928 V8. All alloy, twin balancer shafts (design licensed from Mitsubishi!). There actually were 924s with the 2.5L engine. One was raced and rallied in 1981 and still called GTP (Race) and GTS (Rally), as were the previous 2.0L race cars. This car pre-dated the 944, introduced in 1982, for which this, the 2.5L type 949 engine, was designed. In 1986, they produced the 924S which used this 949 engine in the standard 924 body, with 944 suspension.
