Gramps unleashed



This thread is dedicated to any modifications I do to Gramps (the 78 924 non turbo). The picture above is a bit of a beautiful joke (photo credit: the interwebs), however, because I don't plan on making Gramps into a "Giant Killer"... he's more of an everyday sportscar, but some things aren't quite up to snuff IMHO.

Sigh... I could stare at that picture for hours... before the days of carbon fibre when an english wheel & pop rivets & sand bags were handled frequently.

------------


The heater fan hasn't the best reputation and I found the body had several cracks in it. Repair: I'm going to patch it up so it was better than before, but here's the "hot Rod" solution that I'm hoping will work:

Extending the 5 fins by about 25%. Riveted & glued on with a strong bonding agent. I'm excited to try it!! :p

Yes the fan works better & there is not any extra vibration/noise. I also bypassed the variable resister (or whatever you call the dash level control for fan speed) & plugged in the ground directly to the fan motor & that made a big difference in fan speed. Now when ever the key is on then I have full fan power. Will probably install a switch for that. I don't like the cable/control set up. The whole heater set up is crap.

Lately my preference for engine performance is torque. Lower rpm hair pin turns is what I've been dealing with and rallye style driving has captured my imagination & desire. And torque is nice to kick the back end around.

Since I have two cars (Gramps and Wilson) that I drive a lot, I notice where each car shines. Gramps is far easier to get into & out of. His seats are factory '44 Recaros. So nice. His engine is a far cry from the 2.5 litre though. So I've been exploring some options.

In a nut shell (I'm running out of time this morning & must go to work):

I have 944 2.5 engine parts; enough to consider placing the Porsche 2.5 in place the 2.0. I am considering converting the mechanical CIS fuel injection system from Gramps to the larger engine. What sort of job would this be & what are the results?

The back of my mind worked on it & the search engine confirmed: The 1979 928 model was CIS & look at the CIS injector on what appears to be a 2.5 head. It is possible the injector could be a true bolt in.

You don't happen to have a spare 944 intake manifold do you? I should have a set of unknown quality 924 fuel injectors. They should be almost identical dimension wise (unless someone knows better than I do) and we could see how they might fit.

If no one else will say it I will. This possibly one of the worst ideas I've ever heard.

Let me see where those are... they should still be in that NA head I have.

More like "if you're going through the trouble of doing an engine swap it worth while"

Well all I said was I'm thinking about it. There are several other aspects that need research. Such as clutch/bellhousing/input shaft/ign/engine mounts/harness adaption, etc.

Common belief is the n/a CIS can be used for a built 2.0 (150-160 hp). Well that's stock 2.5 territory.

My exploration into the swap will reveal more. If you've already done this research then feel free to post the info. In the end I think I'll just rebuild the stock 2.0. (It's leaking and someone appears to have stripped out all of the allen bolt heads from one end to the other). Nice

Or I might put the Motronic ecm & harness in with the 2.5. Right now Gramps is finally parked on the street & Wilson the white 944 finally gets some well deserved garage time!

If I rebuild him I will try to bump the compression to 11.5:1, I will regrind the camshaft on the bench with common hand tools & perform my first port job and get the flywheel lightened. Probably add what? 20-25 hp? All for pretty cheap. But will it last? Will it work is the question.
