any idea of width diffrence on an "f" series?

So there is a few options out there, a mate at work who owns an AE86 told me that the TRD diffs that are available( not cheap for the genuine unit) are pretty much the same as the nissan/datsun unit, pretty much identicle!

thanks for all the input.

ANOTHER GOOD Toyota Diff option is there
"F series" model diff 7.5", Its a 1 size down from the Hilux diff so your getting a weight saving , The crown wheel size is the same as the nissan H190 , stud pattern is the same as the Nissan 4 stud , AS for LSD`s there is a lot to choose from @ the right price , The F series diff came in Live and IRS form , But the same IRS LSD can be used in the Live axle , the factory LSD`s come from a certain model lexus Altezza IS200 and also the Ma61 supra , Aftermarket diffs : Power brute ,Tru - Trac make lsd`s for the front of a IRS series diff in a early model V6 Hilux / 4 runner which is a F series diff . to get the
F series live axle you need to Find a MK11 Corona MX113 made in the 70`s or the rear diff in a early model YR22Tarago 4x4 . do a search of Toymods , if you need to find the finer details out alot of guys use them as a up grade for there AE86 sprinters

Like I said Cannibal Guinea Pig material, complicated, rare and overall could be worth a Winters Quickchange. Yet the Winters is about 30-35kg about halve the weight. Pity the all alloy Curry housing and strange 9 inch setups are only affordable when the AUD and USD are nearly on parity.

Cameron Datto is right, there is a HUGE amount of different H190 combinations available!! There is 3 different offset diff cases/crownwheel offsets, 2 different offset carriers, 2 different pinion bearing sizes, 2 different pinion input spline variations, 4 different companion flanges, 3 different axle splines-23,27,29, 3 different CW bolt sizes-M12,M10,3/8 imperial, 4 and 2 pinion LSD versions, 90 and 80mm OD friction discs, ramp angles of 45 and 55 degrees, pinion pins set up for tapered bearings and ball bearings, alloy and cast iron carriers, a huge range of ratios from 3.364-5.8?? H190AL H190ML and H190A I think i've covered it all. Majority of this stuff is VERY RARE, hard to combine parts, and costly when it does come up forsale, but can be made into a seriously good final drive assembly for a high power output Datsun 1200 with the right combo of parts!!

Just a query as to what the weight difference is between the R31 and Bluey diffs??
Cameron: What sort of power can this topgear diff handle? 200kw?
I'm still unsure about what I should be looking for, leaning towards a hilux but still trying to keep wight down..

Beware that the H190 diff centre was made for a lot of years and went through a lot of design changes , like axle size , pinion bearing size , crown wheel bolt size , alloy and iron centres , Diff carrier crownwheel offset , THIS Makes it very hard to Interchange Parts In most cases ,but you can still be lucky on a few parts , The H190 LSD`s that you can buy new out of the USA from Power Brute are for the late model H190`s with the Larger Dia crown wheel bolts , You have to be very careful what crown wheel carrier offset you are buying with this LSD so it matches up with the diff ratio you have . I was close to buying Power brute H190 LSD , BUT didn`t buy a lsd because the offset was not going to be correct for the H190 spec i Have , If anyone has Purchased one of these LSD`s it would be good to know what model spec H190 you are using it in . Iam using TOPGEAR H190 LSD which iam more that Happy with .

vanette h190 should have h165-sized axles i believe, 720 h190 is same as s3 bluey, gazelle.

bit of a searh around the net..
