chris u are a total sook :)
its all easy mate, smiles all round

also how u going??

ben

sweet
pressure test is a good idea too but with the simple heads they can be visually inspected
good on u

ben

PLEASE at least get the head vac and hardness tested and milled
the vac test will see if any valves are damaged by ingesting water and will see if they are all sealing
the hardness test will tell you if the head has been overheated excessivley (in which case it will be soft and needs replacing)
adn the mill will remove any slight bend or warp and give a fresh sealing surface

i have yet to see a genuine gasket failure on a stock car it is usually due to corrosion of water passages, or a soft head.

please get it checked

ben

hmm i dont know if i would as its downstream of the fuel
it should have a gasket top and bottom
gt some ultra blue or grey and just rub it into the gasket enough to fill in the "pores"
if not then just a light smear on both sides of ultra grey or blue
make sure that the gasket faces a scraped clean first and even emeried with fine emery paper (400) maybe on a flat surface or a piece of glass

should be ok
if it runs rouugh at idle then you probably have an air leak

ben

hadnt seen that one before but it looks good
be wary of saying it "has all the features of motec" because motec is infinatley upgradeable and can do anything so its features are limitless. but yes it is a lot cheaper. i wonder how it goes on the ignition output side of things cos this can be an area of worry with nissan coil packs especially if they are running at double the duty (wasted spark).
i like tables of values rather then graphs.
looks good though i would like to mess with one

ben

the plastic thing between the manifold and the carby??
that slows heat from being transferred to the float bowl and boiling the fuel. if the fuel boils then it will miss, stall and carry on when sitting in traffic or maybe even when driving rather then pinging.
try to put it back on if you can

ben

sorry to go off topic but i notice jozz looks to have a familiar car to me!!
how is it all going ?


ben

hmm in my opinion go for the autronic
if you are racing then there is only two choices really
the autronic or the motec as they both have a full logging facility which is really good for watching whats going on after a few laps.
the haltech has logging too but it is pretty rough compared
the motec would be better if you want to add on things like suspension travels and g force but this is starting to look like a lot of money
(like a real lot of money)

i have wired setup and tuned about 6 autronics and stuffed around on microtech and ems. i have looked at the programs for the haltechs and motecs but not tuned either.
also i think the uni group guys like the autronic too (when i was there for the nats anyway)
my opinion

ben

not sure if anyone already knows this
i am a bit of an ET pulsar afficionado and they have a really cool thermo fan switch
screws into the radiator directly and has two terminals but does not need a relay
power to it then to the fan then earth the fan!! how neat is that, well i find it cool!
they are switched at 90 degrees and cost about 30 dollars new.

ben

i hav a factory manual somewhere i should have checked it before spending hours trying to measure and model it all out

oh well

looks to have turned out the same but now i can work out more on the anti dive
