Title: convert 1300 to 1600 dual head
Post by: mrmut on September 14, 2011, 21:09:54 pm
Convert 1300 to 1600 dual  head.
Head of 1300 F engine to rewrite the hole cylinder 89.-- to 93,-- whether the head wall will be thin. ???
This conversion reduces the 7,5:1 to 8,8:1 CR  ;D

Do you want to convert a 1300 to a 1600 dual port head?

Then you need to bore the heads. Could be easier to buy 1600 heads

I have 1300, 1500, 1600 heads. ;) I want to try 1300 or 1500 in 1600 , аnd 1600 to open the cylinder 90.5.(1776cc)
I have three engines , and I have two 1303s.

1-1303s to be a 1600turbo
2-1303s to be a 1776 with 2x36 drla

 ;D ;D ;D

Hi there,

I like your plan, machining heads is the best thing to do in your spare time  ;)

Just thought "F" engines always have singleport heads. Dual ports should be from a "AB" engine.

I got only one doubt about it:

Dual port heads for 77mm bore in good shape are getting very, very rare and they are (nearly) the only way to get 12oocc engines converted to dual port engines. In my opinion it would make more sence to build a quick 12oocc from those heads. You can (if you are willing to spend hours & hours) get 100 hp+ out of 77x64.

keep workin`...

just my 2 cent
