Cedric do you know how much HP stock K-JET can handle? I'm sure it is quite powerful in fuel delivery... |
Other factors involved. Turbo used, tune used, exhaust, IC etc. etc. Forum myth say 250bhp but I have never seen any proven evidence of that.
My car already had a 10-15% increase in fuel flow in the metering head so never got the true limit plus I was changing out turbos and tunes during the journey. Now I have 270bhp dyno’d on Kjet with 30% more flow on metering head. It’s pretty much max’d out according to AFR’s and limitations to tuning the fuel delivery with Kjet. Been a long time and money consuming journey….. |
I think around the 245-250 mark seems about right depending on how lean you dare to go, if you have a turbo that's matched for it, good IC and so on, but there might be differences between the s1 and s2 fuel head flow according to the list floating around here.. My kjet is standard s2 and seems to bottom out about there, i wouldn't want to go leaner.
If it wasn't for my engine block being not at all flat and causing head gasket issues, and now an engine rebuild the tuning part itself with IC, turbo upgrade and piping was pretty reasonable. Of course lots of small things like clamps and silicone hoses all adds up, but still very reasonable, assuming most of the work is DIY of course. _________________ 1980 924 Turbo

This sounds processing, but you need to add weight lost to the list, lots of it.
A fair bit of weight can be remove at a cheaper price than adding hp for equivalent result; higher hp to weight ratio.
Also, on my car I end up using factory early sport seats instead of aftermarket. Descent support, comfy and great look.
Good luck with the project and keep us posted.
And we need pictures, lots of it lol _________________ 1976 924 N/A ROW SOLD

$20-30k estimate on that list of work
Very little is bolt on. Most will be DIY or paying a pro to fabricate if you have some limitations on skill sets. Break it down into sections and work out what is manageable in smaller chunks. If you try to do too much too soon the project will fail for sure due to lack of motivation and potentially funds.

Yeah I know its going to cost a lot of money, and will take a lot of time. That's part of the joy of restoring a car. I'm going to try saving as much as I can by doing most of the work myself though. This car is teaching me a lot of new skills that I've always wanted to learn and use towards other projects such as welding. Not only that, the knowledge gained and mistakes made on this car will be invaluable to me for future projects. I'm really young so these experiences will help me tremendously. _________________ Porsche 924 Turbo - Current Project |

Yeah, some weight will be saved, but I'm not looking to remove or delete much from the car. Some new parts might be lighter weight, I'll try to see the weight difference of the car by showing before and after weights on old and new parts. My seats are in horrible shape, I'll show that in a video soon.
And yes there will be lots of pictures as I go along as well as videos. I haven't taken much pictures since I've posted, but I just received my tripod in the mail yesterday and I'm working on posting my first YouTube video. And to everyone who will watch the videos I apologize in advance if I don't talk professional or anything lol, its weird talking to nobody on camera and I don't know what to say or how to explain things right. I'll get better as I go along though. Hopefully you'll understand me well.
The first video is kind of an introduction and a basic walkthrough of the car and what my progress is on it. May show some work being done. I hope you all will watch it and show some support. _________________ Porsche 924 Turbo - Current Project |

Just take it slowly, read up alot before you dive and try yourself and you have come along way. My advice would be to at all cost avoid quick and dirty solutions that you will "fix later", those will add up and never be sorted most likely, have seen that happen to many times over the years 😂 _________________ 1980 924 Turbo

Thats the right attitude!
If its a passion and a hobby it doesn't need to make total finical sense. You have fun, you grow and in the end a cool car hopefully.
Don't lighten the turbo to much, it has a lot more sound deadening and insulation than the NA and that makes it a much nicer car. You have boost and with an intercooler you can add more!  _________________ /Magnus, Stockholm Sweden

Keep the projects "bite sized" if possible.
A rolling restoration is more fun. Plan ahead. _________________ /Magnus, Stockholm Sweden

So here are a couple pictures of the inside sheet metal, The top picture is the area where the seat belt mounts to at the bottom of the driver side door. The metal has been cleaned with a wire wheel drill attachment and a coat of primer thrown on to prevent further rust development until I make a proper sheet metal repair. Does anyone know how this is structured underneath this metal? I don't want to start and then find more rust and not go in with a gameplan for a patch panel repair. You'll also see below that the E-brake cable is rusted pretty badly and the tube that it goes through has been rusted pretty bad as well. Going to come up with a solution to that, may relocate the E-brake to the center console and possibly upgrade the E-brake to a sportier one we'll see. Never liked the idea of an E-brake on the side where the door is. If anyone has done either before on their 924 I'd like to see how they have done it.
The bottom picture is the passenger floor pan and its starting to rust up in this area because of a leak that I suspect is from the battery tray. The floor pan is starting to flex easy when I put pressure on it and the driver side is not like this. The battery tray is starting to rust out too and I'm also going to do a proper sheet metal repair on that as well. Since the car is outside I have been able to detect the leak. I wouldn't have been able to tell if it was inside a garage lol. (I cover the car with a tarp now, Don't worry) But I'm hoping the leak is a simple fix and it doesn't take much. In the upcoming video I'll be posting soon, I'll be removing a good bit of the sound deadening and checking the status of the floor pan underneath.

Also does anyone know where I can get a replacement floor pan and battery tray, and if they even make replacements?
I'll post a pic of the battery tray soon. It's pretty bad. _________________ Porsche 924 Turbo - Current Project |

I much prefer the handbrake (I'm from the UK) on the side. It feels a lot more natural. You can adapt a 944 handbrake to fit in the same place, it just needs a couple of holes slotting with a file. Its a better made, stronger lever and doesnt flex like the 924 one. _________________ 1984 MY 924 2.0 NA

There is a good reason for the hand brake to be on the outboard side, there is simply no other room for it with the high and wide tunnel in the middle. There is no downside to the placement other than it can be hard to reach when you fit a roll cage.
You have to remove the bitumen sound deadening on the floor and battery tray to se where you have rust. But it is common to have it leak in from the battery tray, that area is trick to repair lots of overlapping metal. On the floor its common to rust in the front corner of the sil both from the inside and outside. Dirt and moisture collect between the front fender and body and rust it out. Here there is also lots of overlapping and interconnecting sheet metal.
There is not much panels to buy, you will have to make most patch panels, that is tricky.
I'd suggest Fitzee's Fabrications on youtube https://www.youtube.com/channel/UC6JPmJ_aicru8XPWr3EvJnw/videos
He has some really neat content. Oldschool. _________________ /Magnus, Stockholm Sweden

I'm digging into the sound deadening now, this stuff sucks taking off. I'm sure there are easy ways to remove this stuff quickly, but I'm just using a hammer and a flat head screw driver for now lol.
I've seen his channel before and I've watched a lot of his videos, that man can do a lot with very little and the end results look like it was never even repaired. He inspired me to do a lot of sheet metal work on this car instead of finding someone to do it. The methods he uses I try to use because I don't want to spend thousands$$ on fancy tools. _________________ Porsche 924 Turbo - Current Project |

If it's hard and brittle a wood chisel works.
If its softer so it wont "splinter", then a heat gun and chisel/scraper, smokes a bit so have good ventilation and be careful with surrounding things... _________________ /Magnus, Stockholm Sweden

I've finished recording most of the first video, working on editing it now. Looking to post by this Sunday. Turns out my floor pan was solid after all. The flexing was from the sound deadening soaking up water like a sponge and then when it dried up it would sound crunchy and it looked like it was rusted around the drain plug pretty good but it was just surface rust. So I shouldn't have to replace the floor pan now. The seat mounts are still solid as well. Took most of it back to bare metal. All of the sound deadening is gone, it was hard to remove with a screwdriver and a hammer but I got most of it with that. Ended up using a grinding wheel attachment on an angle grinder and that took it off pretty easy. Gonna use that from now on on the other side. Threw a coat of primer on to seal it up. Still working on getting it out of the rain. _________________ Porsche 924 Turbo - Current Project |
