Firstly thanks for the replys, its funny how having people make comments on the project really pumps up the enthusiasm.
One thing I'm surprised no one has asked is why I'm even bothering to attempt this, cause I'd be stuffed if I could answer that one other than why not.
Ok on to business. Here are some of the ideas I've been working over in my head: Comments are welcome, ideas are appreciated but if you just want to rag on me expect a prompt negative response.
As I have a complete aus spec R31 skyline I'd like to use as much of it as I can to update the cedric. In some ways this makes things twice as challenging because I'm working on ways to udate the cedric and at the same time ways to update the R31......
1: Drivetrain: RB30/25det + 5 speed and R31diff. Alloy rad & intercooler both blacked out.
2: Front suspension: This is where it gets interesting the R31 has a strut style suspension where as the cedric runs coils. I'm wondering if I should bother try to improve the cedric's suspension & brakes using the stock running gear as a platform or do I use the whole R31 front end. ie struts, Lca's, cross member, strut towers, etc etc. As much as option 2 sounds like much more work I wonder if in terms of work vs reward it may be the better option. The second option may even mean grafting the R31 clip on to the stock rails. This kind of idea is done a lot with 40's & 50's customs that often have limited range of spare parts.
3: How the front brakes will be done will be determined by the factors listed above but I have a pair of R33 gtst calipers and rotors I'd like to use. (I know that they require adapters to use them with the R31 stuff)
4: Rear End: I'll keep the stock R31 brakes and convert it to 5 stud, until I compare track widths I won't know if the diff will need shortened. I'll try to use the stock geometry but a custom 3 or 4 link isn't out of the question.
5: Anything thats usefull from the skyline will be retained, ie fuel tank, brake booster & MC, clutch, dash with mods, front seats, main electrical harness, engine will be the RB25's harness and ecu.
6: The cedrics body is for the most part quite good and the car came with lots of trim. Here are the plans for the body work: Shave antenna holes, door handles & drip rails. Add a roll-pan to the rear and re-locate the number plate from the tail gate. Delete most of the trim.
Of course all thats left to do now is everything but that outlines what I'm planning to do to hopefully create a tough street car that can also be taken to an autocross or drag day and be fun to drive.
