Hi,

first things first: Cool to have Israeli's also driving AX AND coming to this forum!!

Sounds like you have the same setup as my former GT (a grey one).

I had a 1587cc TU5J2 engine with also a 284 Kent cam and a vernier pulley. What we did to install it was mark the camwheel, then fix the cam from on top (with the head cover off) and remove & fit the new camwheel.

After this, at least it runs. The best is to have it rolling-road tuned afterwards.

I managed to extract just over 130 bhp with a worked head, a set of throttlebodies, a programmable ECU and some other stuff, but it wasn't really finished when the engine blew (due to a broken cambelt). If you get it right you should be able to push it over 140.

Goodluck dude

nope, I remember we had it slightly advanced from oe but not exactly how much. Don't think we even measured for a setting, I had an experienced help so he just set it the way he thought it should be..
