Great work, all cars get better when used headlights from golf mk1 can be used, they are dirt cheap. Or at least was, a few years ago.

Nice to see you get excited about driving your 924 and working on it.
You must be one of the early birds for this year's 924 season.
Gets me interested in getting mine out of hibernation and further sorted out.
I miss driving them both quite some...so tired of lazy farting diesels.

Get the sealed beams cheap and keep it factory, in the long run its better...and you get to keep the pop-ups...which is a fantastic thing.

I don't know if you're allowed to use European headlights but my 34-36 year old headlights work really well. I never replaced a light bulb..i suspect they are either the originals or really old ones.

Cheers... yeah, we've had an early break in the weather here in Detroit... last weekend was 65F, and about the same is planned today... I might even put shorts on and go for a run, now that the Turbo is happy! LOL

We can't legally run Euro/H4 headlights... but no-one checks. I have, in the past, run 80/100W bulbs, loved those... but now I live in the city, not worth the trouble for all the extra wiring. So yeah, probably just chase down some basic 7" sealed beams, for now. Still not exactly certain that the popups will interfere with the IC install... thinking I can probably just as easily rework the end tanks etc, maybe squash the tubing a little, and make it work... we'll see. Eventually.

Hell, right now I'm most interested in putting in that bleeder and cranking the boost up to 10psi! Missing so much fun... and when my test cars are 650hp/650 ft-lbs (or maybe more? ) I gotta do something to try to catch up...

Oh, hell, since all I need are the basic 7" sealed beams... they're as cheap as $4USD on rockauto.com! LOL yeah, even better than the $11 local at the corner... and since the car's gonna sit again for poor weather oncoming... I can wait till they ship...

I've owned this car for a good 15 years or so, and never succumbed to the temptation to raise the boost from stock.

The boost gauge, regulator, and intercooler I've all owned for almost as long.

Now that the boost gauge works, I think my self-control will be lost fairly soon...

I have this compressor housing to fit a US 931 S1 comp wheel (2664) if you want to try it..



Then you can shoot right around to a fmic like mine, or give you other flexibility aiming the air cannon..

Makes things a bit easier...


You can install in situ, without pulling the turbo, with a 10mm like this..

Good thought, thanks - but if I get headed in that direction, might just build up a K27 hybrid, for that matter...

K28.

Fixed that for you

Source from 1989 951S. Direct bolt in, just swap on the 931 hot side housing.

I think even the K27 is overkill, simply too much for street fun.
924 is in all factory forms a light fun, safe and easy to drive sports car.
Add a K27 or K28 and you take away all the fun you can safely have with it on the road.
I would intercool my 931 only for longevity. 170hp is just enough..perfect balance.

Everytime I turn my boost back to 0.7bar/175bhp I find myself turning it back to 1.0bar++ /225bhp super quick. Whilst I will put less stress in the car/motor on low boost, the noise and theatre of 1bar+ boost always puts a bigger smile on my face.

Meanwhile, I'm sitting here with .45bar, like WTF?!?

Yeah, I think that'll be the next step. Already been feeding it 93 octane anyway...

Pop it over to 0.7 and you're in for some fun. Why only 0.45?

+1 Dans boost controller is perfect for making the wastegate dual port. Up the boost to 0.7bar. Use higher octane fuel. 93 is far too low to have fun with boost

Did I mention the car's bone stock yet? So yeah, stock boost, which is only 0.45 here (US).

93 is easy to come by. Don't feel like paying for race fuel on this car - it's a DD!

Plus no charge cooling yet. Need to add that, and better engine management (slowly assembling the pieces), but want to enjoy driving it for a while. I have enough cars torn apart, don't need to add this to the list for major surgery; after all, it's only just now coming off the disabled list having been there for years due to engine rebuild then poor running.

So one more small tweak (0.7 bar), some cosmetic/enjoyable upgrades, then just drive it for a while. Should be fun enough. What're we talking, something like 160-180hp for that? For now, I can deal...
