[Chattering At 60km/h]

might be become my habbit drive at 5th gear@60km/h but my previous RB20det no chattering at this condition. The reason why I'm asking this issue is to know the chattering root cause.

[Hand Brake Help]

I done it but with R32 Handbrake, Dashboard & center console

[Rb25det In A Cefiro (a31)]

I just finished intall the rb25det s2 engine into my A31. Everything fine except the aircond system. Dashboard, AC blower, & Cooling coil from existing R32 due to R33 dashboard can't install to A31 so all the socket from R33 will transfer to R32 equipments to suite the R33 loom.

[Tein He]

Somebody offer the S13 TeinHE (Drifting Spec) for my Cefiro A13.

My concern, Is it suitable for onroad use ? The load spec F/R is 8kg/6kg.

Just an idea....

Can we change the cooling fan from direct drive to electric slim fan.

Reason : to reduce the revolution load
