Hey SAU!

I have a tricky question to be asked and sourced i currently own a 1985 MR30 Skyline

Before directing me into previous made topics i explain mine is completely different, my MR30 has had a 5 speed RB30 conversion

and i wish to do the s13 coil-over conversion!

my problem in being that the RB30 is alot heavier than any standard sr20, 100kg to fact!

Therefor i have been explained that a standard s13 coil-over (Which usually hold a weight rating of 8kgs at front 6kgs at rear)

i am looking for a 12kg front and 8kg rear or shall 8kgs front and 6kg front be fine?

Help is very appreciated

Ty!

Walker.

s-13 conversions are done all the time in r31's....

not to many people think quite that far into the process ie engine weights. do it, see if you like it at standard spring rate, change them if your not happy.

are you going 2nd hand coil overs or brand new, you can at a small extra cost normally get different springs/rates when buying new.

Come to the Classic Skylines Section.

S13 and C210 weigh the same.

Seeing as R30 is a C210 with a newer body on it i wouldn't think they'd weigh much more.

The 8 & 6 springs will be fine.

Socrates the difference is ive put a 250 kg RB30 in it making it alot heavier at the front.

are you emailing BC directly?? find a dealer/re-seller for BC coil-overs, they want your money and will answer faster..

option 1 garage in Brisbane offer both HSD and BC, look around for a more local option

i ran HSD HR coil overs in my R31 (s13 conversion) 8kg fronts and 6kg rear, standard spring rates off the shelf. for a daily driver they were stiff but fun.

i also fitted s-13 fronts in my HR30, can't remember if the r30 tie rod ends fit or not. that may be a more pressing thing to look into.

      I replaced the whole clutch line with the chase bays braided hose, I think it removes that loop, is it the short hose that comes immediately off the slave or is there a drawing in the manual to find what you’re referring to? It was just re-bled when I upgraded to the nismo slave, old slave worked fine but I thought that might help, didn’t change a thing. It’s like the first half of the pedal is pushing air and then when it finally actuates the master the friction zone is tiny. Makes it practically impossible to launch the car

      Yep, that was one of the things we learned fast in the past with our MX5. When you drive with the top down, you are effectively standing out in the sun, 100% of the time, and not getting in any shade (because roads aren't shaded generally!). Just like standing out in the middle of a field on a sunny 27C day is a bit of a bad plan, so is sitting in a MX5 without sun protection.

      I also just ordered some Frankenstein bolts and side mounts to fit a hard top Just in case I do find one, basically so it doesn't need to be fixed to the car with only the front latch.......and then gaffa tape to keep it in place for the RTN journey from wherever I get it

      If your temps are fine now, you probably won't have any issues with where your vents are as they don't look right up at the windscreens high pressure area, so any differences when giving it the beans for extended happy laps would be minimal, but, they should vent heaps when stuck in traffic  Much like how that reverse cowl on my SS let "visible" heat out when stationary, but, because it was basically at the windscreen my coolant temps on the Hwy actually raised because air was being fed into it at speed (110kph), to only come back down to around 90° when I got off the Hwy And your 100% correct about the NC currently not needing vents, but, if I was to add a turbo, and a oil cooler and intercooler in front of the condenserand radiator, and then take it to the track???? It is apparently a recommend requirement if I don't want to worry about coolant or oil temp issues, but, any of the above are possible scenarios, over time As it sits now, with the triple pass radiator and stock air conditioning system, I have absolutely no issues with either temps or air conditioning efficiency, I've been basically daily driving thie car for the last month, both on the Hwy, and peak hour, bumper to bumper traffic, but, that's pretty much expected from basically a standard engine  Talking about no issues daily driving, it was 39° the other day and I was sitting in bumper to bumper traffic on the M5 and then M7, with the top down, and with the air conditioning blowing nice cold air on my feet, balls, and face, well, there was one issue, my head and arms got pretty sun burnt Note to self: leave a hat and sunscreen in the car for such days 🤣

      I would agree, unless you need something specific to the HV motor/battery side repaired or investigated, any mechanic will be able to perform normal services, but if you prefer, maybe look for a mechanic who regularly services/repairs Nissans, the VQ engines are pretty common in the Nissan lineup.  Sorry, I can't make any suggestions, I don't live in Vic.
