Hi all,
I am currently planning my Mk1 Capri rebuild and just wondering what people have been doing fro brake upgrades when undertaking engine conversions?
I am currently looking at Nissan RB25 or VQ35DE (still finalizing measurements etc) so was thinking of utilising as much Nissan (silvia) components are possible to assist with engineering (I am in QLD).Are there better bolt on options? Should i buy an off the shelf unit and fit to the existing struts?
 
Thoughts on diffs? Someone said the me that the Mazda B2600  2WD diff was a good option as the ratios are better than Hilux and just as well built.
 
Its still very early planning stages so I am wanting to take on as much advise as possible before outlaying any money.
 
Thanks,
Kieran

Could easily wait till then. Just with standard booster and master?
 
What did you do for the rear?

What else have other people used ? Will be for a turbo 4 or 6 conversion around 300 to 400 hp.
What about fitting out the original diff with upgraded, maybe quafe components?
Thanks

Just seeing what others have done with engine conversions and diffs?
 
Wont be a great deal of power (4.0L V8, around 350hp and similar Nm)
 
I am thinking building up the standard diff might be a good option and save getting things cut and shut.
 
Any opinions/thoughts appreciated
 
Thanks

I am planning on using a shortened Falcon BW78 diff in my car. I want to use it as a road car so factory ratios should be ok. 
Heaps of aftemarket ratios and centres available if needed although not as easy to swap out as a Banjo style of diff.
Will use the standard falcon rear brakes that came on the diff. Haven't sorted the front brakes out yet.

Would be great to see some pics and approximate costs when you get there.
Working through it financially if using the standard diff housing and by the time you buy new centre, new shafts, change to discs etc it would have to be more cost effective the route you are going down i imagine?

I used the Borg warner in one of mine. It's a better option than the original
Cheaper for LSD set ups, has tapered roller (axle) bearings, heaps of cheap ratios etc

Hi mate as you may have seen my build on here i used a 3.7 ford v6 it was a east west engine and i had to get a sandwich plate made to fit the t56 gearbox. They do fit but its tight.
i used a 4x4 hilux diff a early one and didnt have to cut it down.
good luck with the conversion.

Early hilux diffs fit, however you do end up with drum brakes. Hiace diffs are the same so you may be able to get better ratios with a centre/carrier from a hiace?

A lot of the UK guys just use the atlas from the capri with upgraded internals for their V8 conversions.
