Hi Gentleman,
I will share my experience in cloning a 993 3.8 RS, from a 964 C4 (except bodywork).
I’ve researched, but incapable to find 1consolidated thread w all the Part Numbers (bits to connect the dots).
I‘ll document my 993 3.8 RS Clone* works, for the benefit of anyone interested in the superced Part Numbers.
Before I start, I would like to give my heartfelt thanks, to many folks here for advice.
I must first explained that the previous owner badly forward-dated** to 993 3.8 RS.
Many of the parts have either damaged or mismatched, & no speedometer readings!
With endless unexpected damages / meshed-up parts, & my fundings quickly drained (a common problem with cheap fixes and aftermarket Macgyver mixes).
The issues ranged from Fuel Line Leaks, Engine Oil Leaks, Electrical Fires from all the Macgyver Splicing, damaged ABS Parts/Wiring/Booster Pump, no Speedometer readings till date from ABS, damaged G50 6-Speed Transmission, destroyed LSD, warped & worn Clutch Assembly, damaged Bushings & Bearings, damaged Starter, damaged Tachometer, etc (the list goes on… haha.).
So, most of parts replaced are NOS with latest supersede Part Numbers.
But due to limited remaining budget, some “pre-owned parts” are used (hence the older/pre-supersede part number shared below).
I am terrified of mixed-matched & aftermarket parts, as they are just not meant for me.
So I am adamant in keeping everything factory 993 3.8 RS, as a clean 1-make (does not make sense to re-wield the suspensions’ mount and transmission tunnel area, hence only the Shell remain as the 964 3.8 RS widebody. everything else 993 RS.).
I will build this 993 3.8 RS clone with all factory parts & my daughter will manage it as I’ve been in and out of the hospital.
With only a working 993 3.8 RS Varioram engine + 964 chassis, below is my journey.
