Spent the afternoon swapping out the steel Volkswagen IRS trailing arm for the early Porsche 944T semi trailing arms. They moved the wheel/tire outside the body by 50mm, but more is to come once the flares arrive. Only required changing the pivot bushing from the Porsche one to the Volkswagen bushing.

Soooo, I've been wanting to be able to 'sit' in my Ghia and make vroom, vroom sounds for a while. Challenge was...the Porsche seats I had weren't bolted down, and were super heavy. I scored a deal on a set of Corbeau Forza fixed back seats and needed to fabricate some brackets. This was my FIRST time welding up something that wasn't practice coupons.

Let's see how they work with me and headroom now.

I love great tips that get the job done and save me money.

I was looking into oil cooling for Raketenhase and Marco from Mansispeed.com made a really cool (pun intended) recommendation. Since the 993 was a much larger air/oil cooled motor that needed an efficient cooler to keep oil temps in check, he recommended I get one.

I looked around at various oil coolers of any 'real capacity' and found that they were a lot of money...not like that's typically an issue for all of us here...but I was able to on eBay score this massive oil cooler for $175!!! I just had to order up some metric to AN fittings for the top and voila...more cooling than I can shake a stick at!

good work, you're are racing ahead. Welding looks good too.
have you settled on bump stops for the rear arms yet?

Wonderful to see the oil cooler. I did a search, could not find spec's such as it size,maximum pressure the cooler could hold. What is its size? I was going to buy something from spruce aircraft parts. Their prices are up there, your project is coming along very nice.

I used a generic bolt on bump stop, I will take a photo, it bolted through the top

Hey effvee,

I would imagine the Porsche 993 would be capable of rather high cold oil pressures that would be similar, if not greater than our 4 pot engines can produce. That being said, here are some photos I just took of the cooler for you with a tape measure for scale.

Let me know if you need anything else.

First photo - width of the core / unit
Second photo, thickness of the core
Third photo - overall height of the core
Fourth photo - overall width including mounting tabs
Fifth photo - total height of the cooler

I've always been a huuuuuuge fan of the Germanlook style, one of the biggies has been the use of Porsche wheels, which obviously means Porsche brakes. I decided to run 944T as they've been used quite a bit in various builds I've seen. Frank @franklinsvwerks in Kent, WA took my lowered spindles, mated them with 944T spindles to allow me to 'bolt-on' the 944T brakes up front.

I installed a magnesium cased Porsche 915 gearbox into the Raketenhase, but realized the CV's wouldn't clear the frame horns. Since I 'hate' cutting metal, I figured I'd try to raise the transmission to clear the horns with some 'spacers' I made from some washers to give me close to .25".

Still may cut the horns after my plasma cutter arrives. I like how clean they cut.

Stay tuned.

i was looking at these bump stops, available in different heights and different compressions:

i thought I could drill and tap the depression in the arm and screw it in with loctite.

Hello again, how do you plan to address the brake biasing of your choice? Since I'm having IRS trouble presently, the only thing I can do is, watch people that dont have IRS troubles getting it done. At a earlier point of chosing brakes; I went with with the single piston fronts. I have somewhere buried in storage a book on the early single piston Porsche, I forget what year. The reason why I had the front calipers fit the rear was due to caliper sizing. I have read other members dealing with their large four piston calipers. But time has moved on, I see others having had success with larger four piston calipers. I am going to re-visit the brakes, At the time the pick-a-parts junk yard had 944, bugs engines still in the cars. I was simply removing keeping up with other members suggestions, and that was for two 1302's ond one 1303. I'm glad I just took suggested parts. Now the new pick-a-parts are very high. Please keep up the good work.

Hey effvee,

Where in Cali are you? That's part of my territory, and once Volkswagen allows regional travel again, I'll be down there (I'm near Portland, Oregon).

My pedal cluster has dual master cylinders with a balance bar between them that allows me to vary the amount of pressure front to rear. IF for some reason that's not enough, I can always switch to different master cylinders to increase / decrease the bias.

Kevin

Hello, I live in Rancho Cucamonga, CA. As stated my project is on hold. Question, the pedal assembly/ balance bar how much pedal area is taken up. I'm going to re-read your posts, don't want to ask the same question twice.
