do these exist? anyone using them and have any thoughts on them? i already want to do a cam swap, might do heads as well if they are available at half way decent price- (i know, i'm asking a lot here) i have no desire to go turbo, want to get as much out of my little VG naturally asperated. comments and links.........

someone on here posted something about nismo heads for the VG i think but don't know if they were for the 2nd gen or 3rd gen and if they were for either the VG or VE. but im pretty sure they make them.

 

There were some VG high flow heads for sale on ebay a while back.
of course their original app was for a 300Z

 

Right i saw those they had huge ports on them, Prolly woulda done wonders with the VG but they were bare heads and i think he wanted $2,800 if i remember correctly.

 

Nismo VG race heads are about $700 each i think...unless you are building a high-CR N/A race block, its not worth it

 

when those were on ebay, I bid $75, hehe
they sold for 800ish IIRC.

 

Pacesetter makes headers for the maxima VG, but its rumored they are of cheap quality. Another member is selling his.......

HEADS, not headers

 

Yep, and those were bare. You had to supply your own camshaft, valves... and find a machine shop to put it all together.

 

too early for me I guess

 

What about porting and polishing the stock VG heads? I imagine you could pick up a set of used stockers and if you are any good with a dremel then gasket-match them and clean up the combustion chamber. Might be interesting to see results on that......

 

i dont think the gains would be worth the money

on the other hand if you milled the heads to get lets say 11:1 compression that would be worth the money

 

Japanese heads are known to be fairly clean to begin with. Not like most American V8 heads from the 60s/70s/80s. If you mess with the ports/combustion chambers with using a flow bench or some SERIOUS experience, you are more likely to hurt airflow not help it. Some VERY minor port matching is about all one could realisticly do diy.

 

yeah, but could the pistons and bottom end hold up to that? also might lead to detonation with out some octain boost.

 

also, would heads for a 300 z VG work on a maxima VG? all the same block and heads? are the 300z heads any better or was it the turbo that made the Z faster?

 

if i remember correctly the cams and such in the USDM VG30ET head are the same as the VG30E however the cams in the JDM VG30ET are different. they are euro spec which is supposed to add 10 hp.

 

when i went to go find out how much they wanted to charge me to port and polish my heads they told me 700 bucks. but honestly i dont think that it is worth it.

 

i was quoted something outrageous like that as well and that was with the heads already out of the car.

 

What do you feel would be a reasonable price for the type of work?

 

i was told 250$ per head for ve heads which would be twice the work as vg heads

i would say 200 per head for vg

 

that sounds much better

 

had my VE heads out of the car ported and polished for 500 by a local reputable machine shop. Ive see some very sick cars roll out of there from vettes to trans-ams to mustangs to eclipses, 300/350z's, and one time only a killer lookin skyline. they do this kinda stuff all the time plus they were rebuilding them anyway for me so it was just a bit more work for them so i got away with a nice price....

 

im planneing to have mine port and polished with forged TT pistons and intake valves with valve job

 

forged TT pistons dont have anyhting to do with cylinder heads
