Anyone done a ZX10R engine in a Westy??

[JT71]

Hi,

Help needed please! I need to replace the engine on my ZX9R engined Westy (the gearbox has gone bang). It's a relatively old engine, so I'm not overly keen on spending the best part of a grand rebuilding the gearbox, and fancy a hike in power whilst I'm considering the options. The favourite choice was a 2007 ZX10R engine (50 extra bhp), but the costs are escalating:
New manifold,
Changing the engine mountings,
Maybe increasing the height of the transmission tunnel due to the increased height of the crankshaft (potentially the biggest job)?
Shortened sump - I imagine I'm going to have to get this made?
Usual stuff - fuel line, wiring etc.

I can get the engine for £1500, but I'm struggling to get the additional bits to add up to less than an additional £1500. Okay - it's an extra 50bhp on the old ZX9R but at £3K it's beginning to look pricey.

Has anyone done a ZX10R engine into a Westy (megablade chassis), and perhaps have a list of things that I need to factor into the build cost?? Are there things here I haven't factored in? Do I need to do the transmission tunnel? Anyone know where I can get a shortened sump without having to get one made from scratch?

Help much appreciated!

You may also need a new prop unless the sprocket adapter ends up where it was. If price is a barrier then for the cost of a few bhp you might have more joy bringing the project in more cheaply with an R1 (5PW is well proven, newer engines might stretch the budget again), manifold is off the shelf and plenty of experience out there fabricating cradles/mounts etc. No need for a modded sump, just a baffle plate. You should head over to locostbuilders BEC section and ask the question. I guess you're a bit off the beaten track for many fellow westie owners to advise.
