Bosch Timing Belt On Rb25Det Issue

[_Sawyer_]

He everyone, I recently installed a bosch timing belt to a r33 rb25det and i had a few issues.

Firstly i installed it as per the good book i.e. turning the engine by hand to set the tension and it was too loose. when i started it it ran but the belt slid back and rubbed on the housings

So i did it by feel and knowing the belt shouldnt twist any more than 45 degrees, so i set it and it worked fine except for a heavy sort of belt noise, similar to a super charger but far quieter.

Now Ive done a few rb25 belts but ive never used a bosch one or had any real noisey ones so i was hoping someone has had a similar experience with one and shed some light on it.

Thanks
