Instead for some unknown reason I decided to research automatic gearbox options for (extremely) future build ideas. Common upgrades for the xr6 rigs is a built zf6, th400, and a powerglide. I checked out ZF's site to get some info on the zf6 when I stumbled on their zf8 transmission. This statement is what peaked my interest: "Although the 8HP features 2 more speeds than the extremely successful 6HP, the dimensions have remained unchanged and the weight was even reduced by 3% to 87 kg (transmission modular system 8HP70) including oil." From this I found a single thread from back in the day about this transmission but nothing useful was in it. Got me thinking, if the dimensions are the same as a zf6.... Surely a zf8 conversion wouldn't be all that difficult? Sure the PCM isn't built for it, but there are ways around this. Solutions have been made for other transmissions so I don't see this being an issue. Imagine an FG with an 8 speed box. I wonder if the box would handle more torque being a newer design? Sounds like a very interesting conversion if it was to ever happen. Imagine a built 8 speed.... There is a market for them in other cars already that use this transmission. https://vendettaracing.com/products/bmw-m240i-m340i-stage-2-zf8-built-trans-1200hp?variant=37581670252734 The hellcat uses an 8hp90 transmission from factory for example. https://www.empnewyork.com/products/emp-zf-8hp90-transmission-hellcat Anyway, thought it would be a good topic to discuss instead of working Edited 20/08/21 02:47 AM by biddie_fiddler Link to comment Share on other sites More sharing options...
