To e9 thread in regards to AC systems.
Our efforts to create a complete integrated AC / heat replacement for classic BMW's has been very successful for our customers. We have produced over 200 unit all have been installed with 100% success.
The e10 (2002) and e21(320i) installs have been the most common but in building several e9's for clients we took the time to engineer a replacement and has worked well for us and for a dozen clients. The only part we do not provide is an AC front face plate but have it in design to reproduce. We also produce special cables to link our cable evap to an orig faceplace (AC or non AC). This is area where using orig cables already linked to controls is easier but sometimes these controls are broken after 50 years.
As for comments get real ! These people have never done business with us. We have build 250 2002's to order for clients all over the world. Sometimes nut and bolt restomods but more common a quality driver that meets customer budgets. It is these quality driver cars to meet a budget that open us up for these potshot unfair comments as they were from day one not meant to be perfect cars but what customer wanted. You cannot compare a 20K car to a 100k nut and bolt restoration albeit even if we are doing a low cost car we make sure that a client could take it to a high end car without going backwards with a quality foundation but maybe not all new trim, high perf engines, wheels tires etc.
Our work with dtechparts has been to productize "kits" (not like Nickle dime part houses) that give a client ability to finish their own car with complete kits. AC kits, stainless trim, bumpers etc. much better then orig, interior systems, engine upgrades, suspension upgrades. Concept is you can benefit from our efforts to bring a classic BMW back to life a reasonable, defined cost but do yourself or source well engineered kits so your mechanic can mechanic not chase parts. We have had dozens of BMW shops all over US, Europe, Asia install our AC kits with 100% success
We have rebuilt several e9's and have two in production with this AC kit as well as our stainless bumper replacements and interior. Happy to share what we know and don't know. Our approach on this AC system just seems to be much more pragmatic then trying to restore and old e9 heat and air box. Unit uses all modern tech easy to source replacement parts, air flow much better and fits into existing drains holes, behind dash, controls and does not require cutting of e9 except maybe for AC lines if a non AC car.
