Apologize if I missed it, does it have MAF or standalone, or is it running standard stock chip DME (computer)?

The power steering in 944s is notorious for leaking, so that is no surprise at all. If you didn't check the fluid level I am willing to be its empty or near empty.

As far as the other steering concerns go, I would be shocked if you don't have damage to the drivers front suspension. That hit had to have been HARD, to taco the wheel like that. Also, when I nailed a median barrier at 50MPH in my 88 NA (black ice), the two mechanics that looked at it said they wouldn't be able to tell without getting it off the car, but said that where the tierod connects to the spindle often bends instead of the tierods, when they take a hit to the wheels. Both mechanics built several custom race Porsches, and one specifically did a lot of work in the 80s and 90s with 944s, and were very well respected in Boston, so I believed them, but honestly have never verified this elsewhere.

How much boost were you running at the high level? I am guessing you were pushing the limits, especially with an old headgasket. I am assuming you know this, but despite being turbo 4s you can't run boost like you would in a JDM car. Many people argue 20 PSI is too high to safely run. But for the pinging specifically I am guessing it has to do with tune/fuel. It's good you backed off as detonation can cause serious problems. If you haven't already I would make sure it has fresh clean fuel that is 93 octane. and if you can figure out what fuel the tune or tunes were built for that would help too. For example, my car is running Vitesse and there is a plug and if it is installed the tune is 93 octane and when it is removed it is for race fuel.

This is very, very helpful. Thank you.

I checked the power steering reservoir, it's full. I think you are correct in the suspension damage is causing steering issues. The steering wheel isn't straight when driving forward. I'll bet something is binding - there was also major corrosion on the strut towers as seen from the engine bay.

Regarding boost - on a quick spin around the block, I noted:

Boost control off: 12PSI +/- (no pinging/ knocking)
Boost control on low: 12-14PSI +/- (no pinging/ knocking)
Did not try on high due to detonation, as you suggested above.

Thanks again - I am learning so much.

I believe Mark Dickey - the local expert who inspected this car, said it was stock DME. There have been mods to the airbox, but the MAF looks stock. I dont have any photos on hand at the moment.

If the pinging you are hearing is in fact detonation/knocking, you might want to confirm what chip is in the DME and what the fuel pressure is set to. If you read the Excellence article about the car, on page 85 they briefly discuss having to swap out chips for different gas and also having to adjust the fuel pressure via the regulator.

Something you might want to consider is going with a MAF kit, for example Vitesse Racing one. Will already come with the right tune you will need, though you might need to upgrade your injectors if they are stock. About as plug and play as you are going to get. As always, lots of information on this forum to research. Tuning 951's have a come a looonnnnggg way since 1999, especially modified ones.

Stating the obvious, the wrong tune will kill the engine fast.

Doesn't this car have a stock AFM (air flow meter)? Pictures would help.

After a few opinions - the 944 needs to get to someone who can accurately straighten any damage to the unibody. First two shops I spoke to wont touch it. First shop doesn't do Porsche and the second shop doesn't have the equipment to straighten a 944 any longer.

I have been using a low tech shop for many years - I may need to go there unless I get some better ideas here.

If you can’t find anything in the US.

These guys are awesome.

With the exchange rate it’s a great savings for you.

They are in Calgary, Alberta

The KMR 968 lives in Calgary that is the sister car to yours :)

When I accidentally put a 2" scrape on a fender flare I had Cosmos fix it for me. Did a great job. Loc (Owner of Cosmos) has invested heavily in getting the equipment required to be certified by many luxury brands. No doubt for something like this he would be where I go. However, not sure how you would justify the transportation costs to and from here to get it done when there must certainly be a place closer to your home that could be sourced. The picture in my signature is my 968 and 944 turbo which recreates a photo in Excellence of my 968 and your 944 turbo.

Soloracer - with any luck we can plan a reunion of these cars soon. I am in touch with Gary Stone who built both of these vehicles - he has been exceedingly helpful with my dumb questions and I am sure he would love to see these cars to together again. Gary is also monitoring this thread.

Thanks for posting this article! As it turns out the Brey-Krause harness bar mentioned on page 85 made its way into my 1990 S2 back in 1999. I also knew Denny Voss as we had met at the 1998 Porsche 50th Anniversary celebration at Laguna Seca in 1998 [hey, I still have 3 unopened bottles of Sierra Nevada Spring Water, courtesy of Porsche Monterey and the Porsche Club of America, Monterey Bay Region].

Cheers.

Very Cool! I have a pretty solid collection of Excellence and Panorama so always happy to share if a featured car pops up!

All 944 Turbo's deserve to be back on the road - especially 1989's :-)
Congrats on the purchase, keen to see progress!
