1400 heads on a 1600 faq
Posted 20 March 2011 - 02:41 PM
i tryed the 1400 head gasket on the 1600 and its a no go. for the following reasons
head studs on 1400(dual port wet sleeve) are a layed out diffently then on the 1600 also the bore is alot smaller on the 1400 so you would have to use the 1600 gasket(duh) problem is the water jacket on the head would be very close to the cylinder bore on the engine.
problems and fixes
water jacket miss alingment
i believe the water jackets could be ported to work
although they would still be very close to the bore and might not last long before blowing head gaskets
head studs not the same. i belive the head stud holes in the heads could be elongated to work,
you would also need to swap the head studs from the fourteen hundered to the 1600 since they are differnt lengthes
things that havent been covered,
compresion ratio change
push rod length differnces (if someone can measure the 1600 ones i can do the 1400.
anyway will try to add pix when i get a chance

Another problem is the compression ratio. My compression tester showed approx 195psi per cylinder which is a bit on the high side. I am in the process of doing a full rebuild after about 12 years and have skimmed 1/16th off the pistons, which the engineers tell me should be fine , to lower the compression a little. I'll let you know how I go.

Out of interest how did it preform compaired to the Standard 1400 GSR engine?
What was fuel economy like?

Kiwi subbie. I have a 40mm DCN Weber carby which was running a bit rich so economy was not great, about 11 litres per 100 klm. Performance wise it was great, just felt like a bigger GSR motor.
