205 has a bigger pump assembly an timing belt on 205 has 2 less teeth!! i learned the hard way using a 2nd gen timing belt on my 215 swap!! blew 3 ringlands!! lithia toyota can get them for you. the 205 timing belt is $100 shipped from lithia toyota.
I bought my belt on amazon (HKS) and the water pump from http://www.tcbparts.co.uk/
You can get all the parts from TCB also...i just wanted a stronger belt, they sell nippart also which is as good as OEM. http://www.nipparts.com/
