rear end upgrade? LS1 swap

Post by **monkel.ka24de** » Wed Apr 04, 2007 7:53 pm

I'm researching what i need to buy/pricing/best places to buy with good price and reliability for a LS1 swap into my s13. I figure i'll buy the engine/tranny off ebay from a place with some sort of warrenty and for mounting i was looking at http://www.hinsonsupercars.com...t.htmbut some of you where saying that place was a rip off and i saw something about them being bad.

But the one thing i haven't come across in this forum is replacing rear ends on s13's. the stock rear end i guess (so i've heard) can only handle 180ft lbs of torque. OBVIOUSLLY i would need to beef that baby up to handle the massive v8.

basically... i'm still new to researching this project so ANY informationg WHAT SO EVER is help. i've alread read most of the topics on this forum about the ls1 swap (congrats to WD on the start up... i think i felt my d!ck move when you started it up). any sites to buy mounts drive shafts rear ends to support the ls1 anything would be much apperciated.. Thanks guys

You heard wrong. The R200 is stout.

I'm putting close to 400 through it.

Keep in mind, you'll want an S15 HLSD anyway, so don't fret about rear diff....

Driveshaft is easy too - measure it, tell the shop what it's for, and pay your $300.

the r200 is the stock rear end on the s13? 400 ft lb torque?

Do you know what kind of shops would make a driveshaft for me? i heard like 4v4/atv/bike shops would... but wth? why would they custom fab a driveshaft for a car when they dont deal with cars?

but anyways thanks for the info.

4x4 trucks have driveshafts

The R200 (stock read end) is quite strong as Greg said. In fact, I cant recall hearing of someone swapping the diff. I'll bet all the high power guys use the stock R200.

If the R200 proves too weak (at 700 lbs-ft??), I guess the next step is using a R230 from a 300ZX TT.

As for Hinson, their stuff is expensive IMO, but they are one of a few companies that make this stuff. Spend some time reading around. Some guys use a motor mount kit that includes brakcets you can weld together to achieve your desired fitment. I'll post again if I find the site...

sweet thanks a lot han. that spec on the rear end was exactly what i was looking for/wanted to know. that makes me a lot less worried about my rear end. now all i have to worry about for it is the hlsd which shouldnt be a problem.

Well, it really all depends on the type of driving you do. If you have good traction and launch the car, you'll snap that R200 easy with the amount of torque the LSI makes down low. It's really a matter of shock loading the drivetrain.

The R200 has held over 700WHP before, but it's also shat itself at 350. Depends on how you drive. If you're going to drag with slicks or drag radials, you may find yourself eating a rear end.

na not gonna take it to the drag strip at all. if anything i'll be road racing... (yes i realize my handling will be wack if i do). but mostly a daily drive... i just wanna pull up next to c5's and sound more mean then their vette... the extra hp is just a nice bonus... lol na but i'll be doin daily driving with it. and racing with friends and stuff.

why would your handling be bad?

a fully dressed LS1 w/ t56 weighs about the same as an SR, less than the KA or RB

youll actually be improving your handling

im actually building a road racing car around an LS1

Post by **hannibal** » Sat Apr 14, 2007 1:28 pm

^ and apparently puts more weight towards the center of the car since the tranny end of T56/LS1 combo is heavier than the stock tranny/motor.

sweet thanks for the much needed/helpful info guys = ) +1

Well my 97 240 LS1 GTO swap will have the J30 VLSD and I'll let you know how long it lasts.

Post by **morrissey223** » Wed May 23, 2007 6:51 pm

ok i feel dumb asking but how do u deal with the driveshaft from the tranny of an ls1 and have it fit on the other end of a stock differential on a s13?

Post by **nismofly** » Wed May 23, 2007 7:10 pm

get a driveshaft made, you have to do that for a lot of swaps

IIRC The J30 VSLD is an R200 unit.

I thought the R230 was what comes in the Z33 chassis? And the Z32 TT still used an R200. I don't know though, I'm pretty dumb, haha.

hey yeah i run a LS13, i have about 460rwhp and torque in it, i have a quaife diff. i haven't had any problems with the r200. it's a very strong rear end.

as for buyng things, SAVE for these,Hinson's headersclutch setupwiring

yeah the mounts, are easy enough to fabricate, use a KA Koyo Radiator! fits perfect! but it's WELL worth getting the headers already done. they fit great! i have a driveshaft here for your swap, it's identical to the one i have in my car, i just got 2 haha. it's for sale. (pm me on that if interested)

yeah cehck out the website in my signature, i have a full documentary on my build up from start to finish in the conversion tech section. i just dont' want to spend a month reposting it all here. it's like 10 pages of material. haha.

hope it helps!

300ZX TT uses the 3.69 R230 (90-93 Q45 uses the same hubs and similar axles, which are 32 spline. The axles have slightly different lengths compared to the TTZ to make up for the size differences between the R200 and R230). The early Q45 R200 has 30 spline stub axles, which I know for sure are larger than the 300ZX NA's. I'm not sure of other stub axle spline counts but I'm sure the R230's are equal to or larger than that.

300ZX NA uses a 4.08 R200.

I can't remember for sure, but I believe the 350Z uses an R200 with the option of a 3.36 or a 3.545 ratio.

The Armada has an R230 with 2.946 and 3.357 ratios with stub axles that are a good deal larger than the Z32 TT's. The R230's are slightly large than a Ford 9" differential...

Thanks for clearing thaat up, I was always wondering the difference between all the diffs.

Post by **Logan76** » Thu May 31, 2007 9:46 am

I would love to have 31' drag slicks, and be side stepping the clutch on an LS13...hehe. that makes me giggle like a school girl, then again you would be sure to break something.

not sure if i'm helping but i know that s2k guys and rx7 v8 swap guys that are tight on money put in the nissan vlsd cuz it's real strong

Post by **black.** » Tue Jun 05, 2007 8:43 am

and havin a driveshaft made is pretty cheap 400 bucks

Post by **WDRacing** » Tue Jun 05, 2007 3:06 pm

Also, Ivan is putting ruffly 900hp to the stock R200 of his drag car. He run's 28" slicks and et's of over 160mph. So yeah, the R200 is a bad *** little set of gears.

I think I am going to use Cusco internal in the R200 on my LS6 240. I am not sure weather to go 1.5 way or 2 way yet, but I think I will be going with the 1.5. With the new output shafts I should be looking at spendin 1100 on the rear. The only thing that concerns me with this is the axels themselves. Iv heard rumors that the J30's and TT300ZX axels are a lot stringer, is this true?

Is the J30 Rear a R200 or a R230. And the TT 300zx rear, I know thats a R230? I think they require swapping the covers to bolt them to the subframe, but once again im not sure.

Also is the TT 300ZX R230 rear the same length as the R200 rear? The reason I ask is because I have already made had the driveshaft made.

Copy and pasted from your other thread...

You need a Q45 diff. 3.54 final drive ratio w/ stronger axles. You will need to make an adapter plate or have a new driveshaft made as the bolt pattern is a little different.

What you need/need to know...

- Diff from a 90-94 Infiniti Q45- '90-94 Q45 (or Z32 turbo) rear hubs (5-lug) - 2 new axles: One from a turbo Z32, one from a Q45 - PASS. side of your S13/S14 uses a DRIVERS side Q45 axle - DRIVERS side of your S13/S14 uses a DRIVERS side Z32 TT axle - Input/pinion flange is LARGER - Need a different driveshaft or flange.

That is your best option as far as I can tell. That diff is kind of an R200 hybrid. Still internally identical, but uses the beefier R230 axles/output shafts and R230 style pinion flange.

Another thing that ive wasted much time and money on is the fact that the q45 output flanges are ONLY compatible with z32 tt flanges. Nothing else. Hate to rob this thread from the grave, but I just did a little experiment, and found some info I haven't found after days of searching the forums: Z32 NA axle shafts have the same hub splines as s14 rear. I was trying to make my z32 or j30 output shafts fit into my q45 diff, but to no avail. Apparently, NA Z32, J30, and S13/4 VLSD shafts are all the same. Therefore I guess that only tt z32 output shafts are compatible with the q45 differential.(At least the 95-6 that i have) All q45 is 6x1 bolt ouput shaft until 97 where they went to 5x1. The most practical option i can think of is to get a 97+ diff, or an earlier diff and use the 97+ output shafts with the j30 axles. z32 TT axles are getting stupid hard to find. Hope i helped some people out... sure wish i would've found this info when i was searching!!
