Silent Shadow

wtf?? yours looks stock!! mine looks like a frigging abortion by comparison . well done there bud. im gunna see how this diff goes. i wont be putting stupid amounts of hp through it. and the rb20 has pretty ghey levels of torque. but i do totally get what you're saying. man i cannot get over how god that plenum looks. i got no idea what the guy was thinking when my plenum was done. but if you saw the rest of the silvia, the whole car is done pretty half-assed.

thanks guys. i actually have no idea what the right way is, so every bit of info helps. can you help me understand why it is bad and how i may rectify it?

yea rb20 man. it's actually ridiculous how perfect the engine and box fits. the x-member on the box lines-up perfect and the shifter is dead centre in the hole. all i had to do was drill one hole in the silvia x-member and it bolted up. the x-member looks like it's on a big angle but it works . the datsun one made the end of the box sit hard up against one side in the tunnel. keen to see how your plenum turned out. that's what has been done to mine but not working so well in the datto. what's the worm drive worth? here's some photos of the diff. i actually got lucky one day and a guy was selling this R30 rear end with disc brakes and the r230 already fitted for $500. i didnt care how much it cost i just wanted it . the R30 rear into a c210 is a straight swap. all i had to do was re-drill my mustache bar for the new diff. this was actually one of the most challenging parts of the entire project. just finding a drill and drill bit that will go through it is a mission on it's own. a die grinder is what eventually got those holes to a good width and over the finish line.. which is like 14-15mm from memory. even though the diff is massive, there is still alot of room in there. yet to do a road test. oh and it's a 3.7:1 final drive. pics: the way they've done it is by welding plates together to make mounts for the input end of the diff. and redrilled the mustache bar to suit. this didnt come with any bolts to bolt it to the k-frame so i just used some spare wheel studs and washers that i had lying around. perfect length and fit. if you need any more pics of anywhere specific let me know. as for rear brakes i dunno yet. but up front i am converting everything to s13. ive got HSD coilovers all round. using knuckles and hubs too. the silvia already had the sumitomo 4-piston calipers fitted which are pretty good but the possibilities are endless i guess.

the back of the gearbox can only go about an inch upwards before it's hitting the car and the engine can only go down an inch before it's sitting on the x-member. i had a look at your pics and the mounts and x-member are heaps different so i dont think i can apply the same technique you used. apart from that stupid high plenum, the motor sits really well. almost factory . but yea as i said, i got a mate who's gunna re-mod the plenum so the throttle body sits lower and bonnet should close properly. can you link me to the speedo ratio converter thingy?

yea my motor's in woo! i'd love to look at your template though. we just slotted the k-frame from the mount holes upwards. so the rb slides down the slots and sits on the original holes. it does sit a little high though. gunna need my plenum modded at this point. but ive already found someone to do that. cheers bud.

gee-zus! that could quite possibly go fast perhaps ;-) im running a screamer on mine . hey thanks heaps for the info man that was a great read. i'm coming along really well with my project. thanks for the tip with the tailshaft and diff alignment. i didnt think it mattered cause there's a uni at both ends? well there is on mine anyway. when is your car to appear in PI mag? oh and hook me up with that converter for the speedo ratio man. would be a massive help!

yea as much as possible! this is my build thread (warning, HEAPS of photos and text) http://www.skylinesaustralia.com/forums/topic/251107-yay-got-my-pics-back/

incredible car sir!! i was forwarded this thread on SAU in my build thread for some ideas. i wish to do my c210 coupe in a similar manner. probably not as extensive or with as much budget as yet but we're on the same page in alot of ways man. i have a few questions for you, but ill save it for a few weeks time when im knee-deep in tears (when i start my rb conversion ). big-ups mate on a fantastic build! cam.
