Not much done this weekend except putting Old Man Emu springs on the Rover. Wilth 31.5" wheels and the new springs, need a ladder to get into it. 
Unichip is at TPC as of Friday. I assume not long for re-program. Ordered 50' of 5/8" hose for the intercooler. Have to mount the radiator in the front of car. Will be taking out my Steve Wong chip this week to go back to stock chip. Also will start mounting a Plx gauge for all the senors this week. Will add more pics later this week.

Replaced Steve Wong Chip with Stock Chip
I know this has been covered several times. Taking the ECU from under seat is pretty easy since you can do it with the seat still in. Just 4 10mm nuts and disconnect large connector. Here are some pics of the change.
Bad luck struck and one of the pins of the Steve Wong chip broke off.
Car started fine with stock chip.
Also 50' of 5/8" heater hose showed up today. May try to mount the radiator for the intercooler this weekend.

Only small progress
Progress has been fairly slow. I have received back the Unichip reprogrammed for a 964. Also started painting some of the various brackets. Did get the PLX gauge mounted which I will have to start preparing the various sensors. Also got a P9290 for the crank bolt - what a huge piece of metal.

Kyle,
I am the keeper of a P9290 crank loaner tool made by another Rennlister. If you pay me for shipping to you and promise to return it promptly I can help.

Maybe I could loan it to you if we are not at the same stage at the same time.

PLX Narrowband Output
Unfortunately not a lot of progress yet due to work travel and a very hot garage. I am trying to get the electronics situated. Do have a question for the electrical guys. The plx air/fuel gauge does have a narrowband output. It is 0v to 1v. It is my understanding that the DME is looking for 0v to 0.8v. Will the difference in outputs be an issue and if so would a resistor in line resolve it (not sure the calculation for the right resistor).
Any help is greatly appreciated.
Hope to have a lot of progress and pics during the July 4th week.

Electronics
No heavy work has been started as of yet. I will hopefully start the larger items (intercooler plumbing) during the week of July 4th.
I did finish pulling the seats and painting the subfloors. Amazing the amount of change and other items that collect over 23 years.
Went ahead and cleaned up the stereo wiring at the same time.

Air/Fuel Gauge Works
Well I hooked up the plx air/fuel gauge and used the narrowband from the system to feed the input to the motronic. It works great. I do not have any check engine lights on and the gauge works fine. Now I just need to get some more sensors (boost, intake temp., etc.).

Radiator for Intercooler Mounted
Also was able to mount the radiator for the intercooler. Not really happy with the location since it will probably cut some air flow to the oil cooler. I do have a manual high speed switch for the oil cooler as well as doing the modification to turn on the fan at lower temps.
The fun part will be routing the heater hose all the way back to the intercooler.

Have worked on the pulley tensioner, but have ran into a little snag. My engine carrier has the Rennline reinforcement gusset added. This adds some thickness to the engine carrier and is causing me an issue with the tensioner being too close to the fan housing and probably will not line up with the belt on the other pulleys. I really do not want to lose the Rennline reinforced carrier. I have thought of shims/washers between the carrier and the mounting studs, but not sure it would work.
