Wondering if the 1.6 16v SOHC head will fit on the g16a block (tracker) inside a samurai. Wiki says that the Swift came with the g series motor so I assume all should be well besides the horizontal distributor.
Does the vertical style distributor fit the cam?
Does the sohc head use any sensors which would require an ecu for operation?
Does anyone know if the header from an 8v (samurai head) would match the Swift 16v exhaust ports. From google images the Swift 16v looks very similar to the Samurai 8v, which is why I ask.
I can only imagine a increase in top end power comparing the 16v to the 8v, but how is the low end as that is also important.
I'm thinking of using this head so that I can cruise at 70-75mph in windy weather with 29 inch tires while having a trail competent motor, is this head reasonable?
Thanks in advance,
Parker.

The Swift uses the same head as the 16V Track/Kick/Vits, you may as well fit the Track/Kick engine which already has the right angled distributor. There was a carb version in some countries but it is very rare, most people run the Track/Kick injection system.

I've actually got a port injected 16v head sitting in a rubber-made with out the ecu, have had bad luck finding the ecu.
Thanks.

r u running a manual or auto-trans?

You seemed pretty interested in running Megasquirt. Whats the hesitation as suggested on swapping the whole 1.6 motor?

Manual transmission

Swap the 1.6 motor with what to replace it? Or do you mean swap the 1.3 or the 1.6, because I've already done that.
I've mega squirted a car of mine in the past, which prolly rose some interest. The hesitation with using the port injected head basically comes down to money. Quite simply, the port injected head needs to be milled and the valves need attention. Also I will need to either order a new thorley header or re-flange the header I have now to fit the exhaust (I don't have a welder). And then I also need the wire harness and ecu. So simply finding a 16v carbed head for 50 bucks to keep me on the road strikes some interest (current head on car is warped).
Eventually far far down the road I plan to turbo the 16v port injected head with an extra turbo laying around, then It will require mega squirt.
*edit.
I may just take the 8v head I have to get milled. Its got a good cam and good valves in it, and the exhaust would be no question. My only hesitation on going this route is me worrying about valve clearance as I know this head has been milled before, but I don't know how many times or how much material is missing.

Yeah sorry... I didn't read the first post correct.
I sure sometimes wish I had just stuck with a simple carb myself heh. Waaay less to worry about in the woods/water. I suppose that feeling will probably change some after the turbo is added.

For what its worth to you, my 16v head was milled .015 if i remember correctly. I also cant remember if it was within the serviceable limit.
Keep us posted

Clay the head to get an idea how much room you have left.

The background of why the head warped. I replaced a 190d thermostat with a 160d one to help keep things cool. Yes it was the cheapest one. I drove a thousand miles and then took a 650 mile one way road trip. A day after the arrival the driver side motor mount sheered and with a messed up RRO passenger side motor mount bracket it screwed up the transmission to transfer case angle. 300 miles on the return to home the 160d thermostat seized close resulting in overheating, a blown head gasket and a warped head. Stranding me in North Platte Nebraska, the trash bag of the Midwest. Once I got home I took apart the transmission and found 4th gear and the rear output shaft bearing destroyed. Got a new transmission, replaced the driver side mount and tweaked the passenger motor mount bracket. 12 miles later and the head gasket seeps oil.
Depending on the condition of the warped head I may just buy another 8v head for 50 bucks.
Are the g series head studs a bad stud to re-use? Should I look into better head studs?

I do plan to use the 16v head I have when work picks up. I plan on keeping the current 8v head in operational condition to keep as a back up. Its got a torc cam and the valves and seats are fresh.
I've been planning on diving into the service manual in hopes for some measurement I can give to the machinist, then he could tell me if he could do it or not.
The ball on this wont get rolling until the 1st of the month. Going on a vacation! Since it is "drive-albe" I wont have news of even the dis-assembly until then. Ill update as I go along, but hopefully its just a boring head disassemble and re-assemble.

Do you know of any reading material on this subject? I google'd for a minute but didn't find anything relevant. I'll look some more.
Thanks,
Parker

No your supposed to replace them. I just ordered a set of ARP http://www.pt2w.com/srd/index.php?main_page=product_info&cPath=7&products_id=50&zenid=c4fkidmdic25ra8jq8ifcn8qq1 (http://www.pt2w.com/srd/index.php?main_page=product_info&cPath=7&products_id=50&zenid=c4fkidmdic25ra8jq8ifcn8qq1)
I have ordered a few times from this guy. www.partsdinosaur.com (http://www.partsdinosaur.com) Good service and he has OE head bolts. Also google around some, I have heard of some NAPA part numbers to replace them as well.
