Spoony Posted December 20, 2011 Share Posted December 20, 2011 Hi Guys, my wheels and tyres arrived, i made some pictures. I have some blue lowering springs which were in the car when i bought it. My FG flares will arrive next week and i plan to install them. Is the car low enought for them??? The tyres are 275/40/17 and 245/40/17 from Toyo R1R. As they are like semi-slicks, how much will the diff hold? My plan was to start with the stock RB25 power, get to 300HP and upgrade to 500HP in the next Winter. Is a quaife diff and some stronger u-joings enought for that? My driveshaft hast 4x M8 bolts, doesnt really look strong to be honest. I dont want to buy a quaife for a lot of money and then swap it to a 300zx diff anyways after 5 pulls. Quaife is ok from the pricing, can buy it in England, shipping and costs are under 1000$. Thanks for your help!! Quote Link to comment Share on other sites More sharing options...
BluDestiny Posted December 20, 2011 Share Posted December 20, 2011 What kind of diff is it? R180 or R200? And take some pics after you put the flares on. Quote Link to comment Share on other sites More sharing options...
Spoony Posted December 21, 2011 Author Share Posted December 21, 2011 I have no clue. How can i find out the differences? The inside of the diff will be swapped anyways to a quaife, im afraid of breaking the half-shafts. Quote Link to comment Share on other sites More sharing options...
Spoony Posted December 21, 2011 Author Share Posted December 21, 2011 Its a R180 diff. Quote Link to comment Share on other sites More sharing options...
Evan Purple240zt Posted December 21, 2011 Share Posted December 21, 2011 Nice looking car! I would plan on upgrading if I were you. It shouldn't take you too long to hurt the stock axles. Quote Link to comment Share on other sites More sharing options...
djz Posted December 22, 2011 Share Posted December 22, 2011 That is a beautiful looking car. When I did my swap (on an S130 w/R200) I used an S13 or R32 front diff flange, they use 4 x 10mm bolts, depends on what you are doing about the driveshaft.

ZT-R Posted December 23, 2011 Share Posted December 23, 2011 I'm running a R230 from a twin turbo 300zx and custom axles. Supposidly bullet proof. The 3.69 is a bit tall but hey i can do 200 in a s30.... Quote Link to comment Share on other sites More sharing options...
Spoony Posted December 23, 2011 Author Share Posted December 23, 2011 Is there any topic with a build of a different diff for a s30? Im doing the first rb25 swap in germany, we have maybe 10 of them left in Germany so there is no real source for information here Found every kind of information for the engine swap, engine loom and brakes, but nothing about the diff.

dizzle Posted January 18, 2012 Share Posted January 18, 2012 I have the Subaru STI rear in my s30 w/ rb25 and I love it! Used the Beta Motorsports adapters. My is about 375-400 whp, but is a street car in every way. The weak spot in this set up is the halfshafts. If you are going to be drag racing a lot, and trying to launch with those 275 tires (looks sick by the way) you are going to need do some sort of a CV swap with whatever diff you choose.

Wedge Posted January 26, 2012 Share Posted January 26, 2012 I think the quaife will hold plenty but the week spot is the front snub ang the axels like others have said. Quote Link to comment Share on other sites More sharing options...
