Title: Head Porting
Post by: Northboundtrain on January 25, 2005, 07:24:12 pm

Does anyone have information on head porting for a 1.6L NA?  I was told by some folks over on vintagewatercooled.com that you can port these heads and get some noticable gains.  Are there diagrams/schematics/etc. that show how to do it?

Thanks

hopefully i will be conducting some testing on this in a few months since i am at school right now i do not have access to the flowbench at work. when i do port a junk head first i will post pictures and results of what works and what doesnt
good luck

i'd suggest that the techniques involved in porting a diesel head would be very similar to a gas head. Already, the ports are better in a diesel than a gas, quite similar to the old 115 hp 1.6L heron gas engine. The ports are quite straight. I'd also imagine that you could polish the intakes to a mirror-like shine as you don't need port turbulence to promote fuel atomization. That should give a bit better flow.

Before and after dyno?

i hope to have access to a dyno at school when i do some alternative fuel research at Kettering University (formerly GMI) this summer, and if it works out then i should have a full three months of time to work on things of this nature, so i guess that i will have to get access to that flowbench at work and get my best cylinder head worked up for this summer and then let you guys know what works for a HP and Torque before and after
later
