XES 384 8 Posted July 18 Hi all,I’m in the very early stages of planning a new project and was wondering if the existing 5 speed gearbox and diff in an XH XR6 would be up to task if the car underwent a V8 conversion? Not looking for crazy power but planning around 300-350rwhp. Cheers Sent from my iPhone using Tapatalk Share this post Link to post Share on other sites

Thom 6,694 Posted July 19 Using a 6 cylinder t5 will mean you have to get a crs bellhousing as the 6 cylinder t5 has a different length input shaft to a v8 one, the diff will be fine and the t5 will hold up reasonably well as long as you don't abuse it ( when I was a p plater I broke many of them with a warmed up 4.0l but they were pretty well abused) 1 deankxf reacted to this Share this post Link to post Share on other sites
