Hey De55id, thanks for your post. I had replaced the belt with the green one, the moment i got the PSK (option when you buy it), so it shouldnt be stretched yet.
An LSD is an interesting mod. Do you think the standard is not capable of keeping the wheels straight with so much power on the regular diff?
A new fuelpump should be doable. Any tools to figure out if the fuel ratio is OK (through obd for example)?

Thanks
