before i do this i want to make sure its exactly the same... YES IT WORKED... READ BELOW!

If the frontier uses a KADE I'm sure the differences were very minor if at all

yeah they changed the timing setup on the s14 to the single chain like altima so im assuming they just used the s-chassis and or altima head on the frontier ka.. so why in the world would they change one aspect such as the idler gear bolt? makes no sense to do that... so in any case i will be finding out soon if it works. yesterday i dropped the s14 head off to the machine shop to be cleaned decked and valve seals installed so once i get it back i will complete the head gasket job using s14 head and cams

Your reasoning doesn't make much sense. You want to minimize down time but you still need to do the head work on the s14 head. So wouldn't it be the same time as doing the head work on the truck?


Unless you have like aftermarket cams or something in the s14 head and you want to use it on the truck I see no point in the "risk" that could be a waste of time and now you have more down time

I'm assuming it's still drivable. Otherwise I don't see the point either. Although I am curious.

That's also what I was thinking. Maybe he is still driving it as is which is not a good idea either

yes im still driving it locally about 2-3 mile thats it... its my only transportation...

also unsure if frontier head will need to be decked.. and frontier ka has 260k miles so valve seals should be replaced while its off.. so since i have a spare head why not kill to birds with one stone.. as long as the s14 head works might as well get valve seals installed and decked and once it is done, replace hg use s14 head with 248/232 exhaust cam swap...

i finished the s14 head converion on the frontier along with the install of two s-chassis exhaust cams. (poor mans cam swap) usually i do 248/248 but since i only had a set of 92 cams 240/248 and a set of s14 232/232 i opted to try out the 248/232 swap...u can swap 240sx cams in the frontier head without swapping to a s-chassis head. u just have to slightly modify the 240sx cams.. since the 240sx head has that last cam journal, and the frontier does not there is a oil port in the last part of the cam... there is also a plug on the inside of the back of the cam u either have to try and punch it in further yourself or take to a machine shop to have it pushed in further to prevent oil spraying erratically from that oil hole.. now the issue i had and what other people have had is nissan decided to change the chain from double row to single row along with re positioning the intake cam dowel to sit at 12 o'clock to match the exhaust cam which screws everything up... so if u are installing a stock intake cam from another ka24de 91-97 then u follow JWT diagram but if u are installing an exhaust cam on the intake side u need to follow my edited diagram to move the timing marks a total of 8 teeth.. if u did it correctly the first cam lobe will look exactly opposite the exhaust cam... they will be facing away from each other... now u can use a intake cam ie the stock frontier intake cam on the exhaust side instead of getting a s14 exhaust cam but my brain was hurting enough and i didn't want to think about it anymore..
you want to get the engine cyl #1 TDC compression stroke.. if ur stock chain is still painted yellow like mine was this is great u can use those marks.. you don't need to bother marking the chain and gears current location because the engine is at tdc, so u can use the original marked links... what i did was remove both cams and install the s14 232 exhaust cam exactly how u would install a stock exhaust cam... then take the chain and match up the exhaust cam gear and timing mark to the 2 o'clock position. Then the idler gear timing mark 6 o'clock position.. install the 248 ex cam on intake side.. on the single row gear there is a mark on the left of the dowel and a mark on the right of the dowel. The mark to the right of the dowel will be the timing mark u will use. this will be positioned on the 10th link from the exhaust cam colored link, being #1.. The tenth link is the one directly after the painted link on on the intake side. #10 on edited pic.. if u have done this correctly the new intake cam lobe should be facing 9 o'clock and the exhaust cam lobe should be facing 3 o'clock.
now the fun time i had of figuring out which cam was what. lol nissan again being weird changed the cam colors around..
91-94 green intake orange exhaust
95-98 orange intake green exhaust
both intake cams the dowel is aligned with the first cam lobe at 12 o'clock.
now if ur like me who had a few sets of s-chassis cams laying around but had no idea which was which. get out ur digital micrometer start measuring the lobes and follow this link for specs... actually pretty easy
