How strong is a sierra dif?
Well ive just come in to some (unfortunate) money...
Rather than buy a kit im going to keep going with the locost from scratch as its the engineering challenge i crave.
However with new found wealth this has opened a new set of options for me with regards to the power plant im going to use, so the first one that stuck
me was S2000(yum) with 240bhp im wondering if the diff will be alright or is this a non issue coz the wheel will spin rather than kill the dif.
Then again im looking to upgrade to a LSD (XR4x4) would this also be a non issue?
Secondly i might look at a 200SX for giggles which would presumably provide a lot more torque.
Then of course i might look at zx12r/hyabusa.

You will want to use an LSD anyway, so just get an XR4x4 diff or a 7.5" cossie diff. Both will be fine with the power/engines that you talk
about.

The s2000 engine output shaft turns the opposite way - for a start. Diff would need to be mounted upside down... not the best way!
The reduced weight of the parent car is significantly less so a sierra diff should cope with little problem. Besides if it goes pop just get
another... I wouldn't go LSD unless your planning on do-nuts - make little use on the road! More weight for no gain in normal use.
BEC is the prefered route - you know it makes sense.

NO no no!
S2000 is fine Hellfire! The S2000 and new Civic type r engines turn the normal way.

ISTR someone somewhere saying the S2000 went the other way - I stand corrected (I'll do more digging!)
OK after a little digging - came up with this; engines pre 2000 the output shaft turns anticlockwise - the wrong way. Post 2000 they turn
clockwise... the normal way. Be careful which engine you choose!

all of the engines as fitted to the S2000 and the "new" civic type r turn the "right" way.

Hi Mr Hellfire
I am interested in the S2000 for my car maybe next year.
So I would be interested in your source of information on this one as I have a Sierra diff too.
Cheers

Yeah i heard about the honda wrong way thing before but theS2000 does indeed turn the right way.
The main reason i was looking at the S2000 is way they screm, so i may indeed go with a ZX12R yet

I'm 99% sure the S2000 turns the proper way. The reason why I think this is because when the S2000 came out, all the kids wanted to put them in
their Civics--which turn the wrong way. They found out quickly that they didn't work! FWIW, I think the CTR still spins the wrong way.
I'm sure the Sierra diff can handle the S2000. Thing is, what not just buy the S2000 diff? It comes with an LSD and would seem more appropriate
for the application.

FYI -
from the Westy list, and I know this is right as I know of somebody that used to rally a Rver 216 converted to RWD with a Honda v6 bolted to a type 9
box and a sierra diff.
"You're wrong. S2000 is one of 3 Honda engines that rotate the right way. The latest CTR and the 2.7 V6 Legend engine also both rotate the
right way...
Add to that list NSX , 3.2 & 3.5 V6 Legend & Current Jazz . Its also worth mentioning the CTR engine is the same basic motor thats used in the
current model Accord , CRV , 2.0 FRV and Civic Type S"

S2000 and new Civic type R (same engines essentially) definately spin the conventional way. Check out an engine bay pic of a new civic and
you'll see the engine over on the normal (driver's) side. Check out a pic of any older 4cyl fwd v-tec car and you'll see the engine
over on the passenger side - it's rotated over 180 degrees so it still turns the front wheels forwards.
It was only ever the 4cyl engines that ran 'backwards'. All the V6s run the right way, so any accord V6 can be added to NS Dev's
list. I'm using the old 2.7 Legend/Rover 827 engine in my car and it goes the right way.
And as chrisf says, the s2000 diff will suit you better if you can get hold of it. As well as being a nice torsen type LSD (as opposed to sierra
viscous coupling) it will have the right final drive ratio for the engine and box (that's not to the the sierra diff might not too though!).

I would go for a LSD, even my old zetec will spin both wheels from idle in 1st if you floor the throttle. Not sure where the bit about it being
heavier than a standard unit comes from...they're both the same size if from a 4x4.

If you have any questions about the 200SX engine option then feel free to ask me as I've owned and tuned both the CA18DET and SR20DET to
reasonable levels (approx 270 and 360bhp respectively with a similar amount of torque - which you won't get from an S2000 / Civic Type R lump).

its torque and relative vehicle weight that will kill a diff - hp is just the rate turning - im sure those high revving jap engines dont have much
torque in comparison .
