Re: 1.3 buildup, or used 1.6?
Yes you are chancing the used 1.6, BUT you never know. The 1.6 I put in my 86 has 135k oringinal on it, with the FI conversion will out pull, out tow, and out climb any 1.3, including my 95 with only 50k. I chose the 1.6 due to the longer connecting rods= more tourqe.
About 4 months ago while comming back from a trial I was behind my buddie in his 88 built 1.3, he got on the CB and gloated "that 1.6 is barley keeping up with me" (note he was turning about 4500 rpms, mine at 2500). Well I gave it some more gas and I gained on him quik, I didn't shift down just the gas. Needless to say he is rebuilding the 1.3 again tring to get more power to beat my stock 1.6.
I pulled the pan on my 1.6 before installing it to make sure the lower end was good, but thats all. BTW I still get 23+ mpg, city/hiway/offroad
If I had to do it again i'd still go with the 1.6.
My 2 cents
