S13 Vs R32 Diff Centres

[MerlinTheHapyPig]

Bid of an odd question.

I know s13 and r32 diffs have different ratios, but can I use an S13 centre in an R32 housing using the R32 ring gear and pinion?

They are both R200 centres, just wondering if this is going to work, because I have a spare S13 diff sitting here as a spare for my R32, I just assumed it was going to fit but I found out yesterday that they had different ratios.

Cheers Guys!

(btw, S13 SR20DET diff vs R32 Gts-t type m diff)

yes you can.

I want to go from my r32 (4.3) and fit a 3.9 s13 ratio. Ill be using the nismo 2 way centre, r32 axles and housing ...

need to find a 3.9 first

[MerlinTheHapyPig]

hm, so are s13 ratios better? I get confused with ratios

So, with a 3.9 ratio would mean say at 7,000rpm in 2nd gear, would you be going faster or slower than with the 4.3 ratio? (i think from memory 7,000rpm/2nd in my r32gtst is around 90km/hr)

If you're going from a 4.3:1 to a 3.9:1 the car will accelerate slower but have a higher top speed.

The difference will be only 10% or less on each though...

[Bl4cK32]

the only reason im going from 4.3 to 3.9 is because the 3lt makes 1st gear useless to drive.

Take off, and change straight away. The 4.3 means accelerate, 3.9 will give taller gears.

hmmmmm

i might consider chucking the s13 diff in and try it out

one thing i don't like about my car, is when drifting on a 2nd gear corner, i am really running out of gear, and coming close to limiter, but the corner is too tight for 3rd, because the revs will be too low when i exit the corner.

I might try using the s13 diff just to test it out.

so back to the original question, can i just change the ring gear on the 32 centre? or do i have to change the pinion also

ring and pinion are a set i believe.

you need to check the splines. 28,29,30,or31. then happy days.
