My car has now jumped timing for the 3rd time in 2 weeks!!!! Luckily my motor is a low compression non-interference motor. I have an SI head on a GSR block. As far as I know the head has only been milled once, and the block has only been decked once maybe twice. I'm using a GSR/Type-R timing belt. My water pump, cam gears, timing belt sprocket, tensioner are all right so don't even start asking which ones I'm running. I called Honda/ Acura and cross referenced all the numbers, but just in case you are curious here we go:
1 SI water pump= GSR water pump
2 All B-series timing belt tensionsers are the same, mine is brand new w/new spring.
3 GSR timing belt= Type-R timing belt, henceforth; SI head w/GSR block = Poor man's Type-R
4 All B-series cam gears are the same

My timing belt is still tight as hell. Does anyone know or have experience with this situation?

 

No that's a new one to me, unless you're not tensioning it properly (rotating it counter-clockwise 3-5 teeth on the cam gears after you slip the belt on when everything is at TDC).

 

how tight should the belt be? how much deflection if any?

 

I'm doing everything correct as far as the timing belt procedure. Anyone else got any input?

 

how is not an interference motor?

My sentiments exactly... what makes you think that what you have put together is a NON-interference motor? just wondering as well...

Have you tried tensioning the t belt manually by prying up on the tensioner with a screw driver and tightening the tensioner bolt?
