Want HiPAC info/opinions

I have 2 CO2 'carbines' that I'm thinking of converting to HPA via HiPAC units. From what I've been able to find, it seems like a very simple conversion and a great solution to cold weather problems encountered with CO2.
Is it just a simple case of replacing the striker spring and screwing the HiPAC unit onto my 2400KT?
Any recurring problems with leaks or routine maintenance?
How many fps can I expect in .177 cal shooting ~8gr pellets?
How many good shots can I expect with the basic HiPAC unit? If I add one 'extension', how many more shots can I get?
Any other info that you care to add will be greatly appreciated, especially the "pitfalls" of converting to HPA via HiPAC.
TIA

Are a lot of HiPac pots, would do a search and spend some time reading over the posts.
Simple installation would be like you outline. No change in valve retention, do change out the front seal to the black seal provided, just screw on the hiPac, and run it at low pressure (like 1800psi). Might need a new striker spring, might get by with just increasing tension on the original. Low shot count.
More complex install would be to add valve retention, use the heavy spring, and run it at high pressure (about 2800psi). Still get a low shot count, but it will be considerably faster.
Either way, would want a steel breech. Maybe the plastic breech would be OK for the simple install, but I have doubts.

I have 2. One on my 2250 and one with an extension on my 2400. Install is easy after you replace the seal on the front of the valve, just screw it in and fill it up. With the heavy hammer and almost 3 kpsi they will sling 15.9 gr jsb in the mid 750's but you get 2 shots and it drops off. Plus cocking is a bear and it makes the trigger pull heavy. They are set up to run in the low 600's and get about 15-20 shots per fill at 25 yards. The 2400 at 40 yds get about 6-7 shots before poi changes.
