AAZ going in to a 914...

Bought an adaptor kit from KEP to hook the engine to the transmission. Everything is apart right now. Should start putting the car back together this week. Next big hurdle is a front engine mount. For those not familiar with the Porsche 914 it uses a 901 transmission same as a bus, flipped so that the engine is ahead of the back axle. Longitudinal engine. Existing engine is pretty much a type four bus engine, boxer 4 air cooled. Mounts on a crossbar from side to side of the car with 2 rubber mounts in the middle. Gong to re use the cast cross bar.
Anyone have much experience with a front mount for a longitudinal engine? First thought is to use a mark 2 jetta mount on the back side of the engine, but wondering if there's strong enough bolt holes on the front of the block to work from there instead. also contemplating using the big holes cast in the block at the front of the engine beside the oil pan... Going to think about it overnight. Should have the engine bolted to the transmission tomorrow.

Anyone got an easy way to hook a 4 cyl gas tach to a W terminal ? I know I've seen something in here somewhere....

You have to rewire the tach to accept the signal from the W terminal

Found a built adaptor. Dakota Digital. Rewiring the existing Porsche tach is over my head. for 69 bucks problem solved.

Next problem.... Somewhere in the past I saw a reference to a VW part number for a stand alone glow plug relay socket and wiring, not part of the fuse panel. Can't find it. Ringing any bells for anyone? If I remember right it had something to do with vans... maybe South African? I can buckshee something together but a nice socket for the relay would be a better way to go.

My 1981's, Rabbit and Caddy have the relay mounted on its own socket free and clear of the fuse box. Might try a salvage yard for one like it. I think the 1980's also had it freely wired.

Thanks, under the hood or under the dash? I've got one older mark 2 parts car here, the others are all new mark 2 or one mark 3. Won't find anything that old in a wrecking yard here, all crushed. that's why I keep a few of my own... that and I'm a pack rat.

Mine are under the dash. Left side, on the MK1.

I only skimmed through your linked thread. I just thought I'd mention that for anything less than 15 psi or so, the T3 is a downgrade from the K14. All you gain is turbo lag.

Aiming for 20 psi, maybe more if I put a cooler in. I thought the t3 was less restrictive on the exhaust side...

The T3 is less restrictive on the exhaust side but the K14 doesn't become any significant restriction until you're over ~15 psi. You should add an intercooler before going over ~15 psi anyway just as a matter of course. Above that point, the heat from compressing the intake air becomes a limiting factor. The K03 that was also fitted to the AAZ was much more restrictive than the K14. In the case of the K03, a swap to a T3 will see a benefit in higher rpm power (at the expense of a big increase in lag) even in the 10-15 psi range, but a swap from K14 to T3 won't see that improvement.

It's on, I'm going to try it. Easy swap to put the K14 back if I don't like it. How's the K24 rate? I have a couple of those on the shelf too.

K24 is basically the same as the T3.
