I've been running one of the original batch LSDs for over 2 years in my Gazelle (H190) & it's very good. It has made the car very stable & repsonsive around Lakeside Raceway. Top work Topgear.

A Bluebird/S12 H190 is 144cm if that helps. Only 3 LSD options available though: CIG, Topgear's awesome Torsens or a plate centre from the US (if they still make them). S12 axles are nigh on unbreakable.

The Dualcab Navara 2WD also has a H190 & is leaf spring. Nothing in common with the BB/S12s though.

Do you still have this motor?

The S12/13/14/15 booster & master are about 230mm wide & 250mm from the firewall to end of the master. I'm using an S15 master on my S12 booster with a bias adjuster. Because it's meant for ABS & 4 pot front calipers I had far too much rear bias using SR20 front brakes and 910BB TRX rear discs. Now that I have R33 4 pot fronts it's back to needing front bias.

PM Replied.

As I mentioned in the PM a guy recently bought an exhaust cam to put in the intake side as it has the same specs as a CA16DE intake cam. I never did follow up to see if it worked, but it's worth a try with yours & I'm sure other members would like to know the results.

I have a CA16DE cam in my CA20DET & it works well with the extra capacity.

That certainly would cause the problem mentioned.

I should have a spare stock exhaust cam if you need one. I"m in Brisbane, but happy to freight.
