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.

Yer, i have read about plenty of s13 coilovers into the mr30, and i am buying new coilovers from B.C unfortunately i have not had a reply from them,

thanks for the input rsx84

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.

      Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.

      Jacks that fit under GTR lips that can reach the subframe?

      My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though.

      Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno

      Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.

      BTW I measured the jack I have, it is 70mm at the saddle but you only have about 700 until it returns to 150mm high at the cylinder so it is good but no magic bullet.
