I'm in love with my Tokyo Marui type 89 however it's lacking in the range and FPS department. However there isn't much information online. Has anyone upgraded one before? And will it be fine on a m100 spring ? Thanks

What power and range are you getting?

I built one from a collection of parts a few years ago; they are "interesting" internally, with so many potential failure points and unique parts, which is why I sold it on as rapidly as possible.

Mine was shooting at about 0.78J and reaching out a very good distance.

So I'm getting around 270 FPS but the hop just doesn't seem to be good enough to get it that range. So I was looking to upgrade the hop and the spring however I'm honestly not fussed about 270fps as that's still more than manageable. Do you know what type of hop it would be compatible with or is it proprietary one?

It is a proprietary two part hop (separate feed tube). https://www.zerooneairsoft.com/products/Tokyo-Marui-Plastic-Hop-Up-Unit-for-Type-89

The sector gear is made of pot metal and is also proprietary, having an extra cam to enable the burst function; the cam for the COL is also in a different position than usual due to the unique gearbox design with its vertical sliding trigger switch..  That makes increasing the power somewhat risky as the sector gear is prone to shredding itself if pushed too hard.  Element used to make an improved gear set, but I have not seen one in stock for years.

This is a good guide to the idiosyncrasies of the Type 89: https://tacticalparts.com/blog/resurrecting-the-champ/
