[FONT="]I've finally joined the club purchasing my first CS. [/FONT]
[FONT="]Serial #[/FONT][FONT="]2240377 was found in Nashville Tennessee, parked in a garage in 1993 with a bad alternator. With less than 35,000 miles, it did not again see the light of day until last month when I trailered it back to New York. It's color is Nachtblau and options are a stick, A/C and a beautiful / original non leather interior. The body is in excellent condition and there is a small amount of rust in the front two fenders, no where else. From sitting for 18 years the motor has seized and from the beginning my plan was to update the motor.[/FONT]
[FONT="]The original plan was a 3.5 and 265 transmission, but found and bought this week was a 88' M5 in rough condition and good running order as my donor motor. I drove the M5 a 100+ miles this weekend, it pulls hard, shifts great and I cannot wait to transplant its motor into the CS.[/FONT]
[FONT="]I have been reading the forum and the information is incredible. Has anyone placed a S38 / Gertag 280 (Combination) into a CS? If so, I have a bunch of questions I hope those more experienced than I can assist with. [/FONT]
[FONT="]1. Manifolds - I assume will fit from the S38 - What are suggestions for exhaust?[/FONT]
[FONT="]2. Transmission cross bar - From M5, will it work on the CS to support the Gertag 280?[/FONT]
[FONT="]3. Gertag 280 - [/FONT][FONT="]Is it the [/FONT][FONT="]the same length as the 265 - Do I need to remove 3 3/4" from the drive shaft?
[/FONT] [FONT="]4. Radiator / fan from the S38 - Are there tricks or is it straight forward mounting?[/FONT]
[FONT="]5. Gauges - North Hollywood can help with the tach and speedo. What is there to do with the oil pressure light?[/FONT]
[FONT="]6. Master brake cylinder - I have read 2002 and 733 are smaller - What is the best available that will fit under the hood?[/FONT]
[FONT="]7. Fuel Tank - There is a return line needed for the fuel pump - Is there any tricks?[/FONT]
[FONT="]8. Suspension - Are there bits that can be upgraded from the M5 to the CS such as swaybars?[/FONT]
[FONT="]9. Brakes - Planned for - From the M5 will be done with new lines and 16" Alpina's.[/FONT]
[FONT="]What problems will I face I have not yet identified?[/FONT]
[FONT="]Two friends are trying to convince me to change my plan and rather rebuild a 3.5 large valve motor with 11:1 compression pistons, Schrick cams and 40mm Webers. Upside is reliability of a newly build motor, downside is cost ... How much would a rebuilt motor like this cost? I possess a 265 Gertag, so it would ease the plan.[/FONT]
[FONT="]Thanks for your suggestions, input and knowledge.[/FONT]
