ISKA8's MITSUBISHI SIGMA GK GSR TURBO BUILD...ENGINE SOLD!!

[ISKA8]

well i went to pick up the car today only to find that the car is still running like crap ?? it has a miss and they dynoed it?wtf anyway there thinking its the plugs now but i changed them before i droped it off? this car has drivin me to complete insanity .so obviously means more time and bloody money!
this car owes me way too much for all the headaches that are involved! i built my vn ss with some complications for almost the same price and made over 389kw atw and im pissfarting around with this car..i love it but i think its gonna be the death of me!

[GLANT]

very strange that is...id get it out of that place mate...they seem to have no idea at all... they blame plugs?? next they'll blame the carby!!

[A112H]

Could be one of the seal on the rotor, I hear they go all the time

Seriously though mate, I think I would be yanking my car outta there

[dvsfin]

if it is your plugs I would be worried about how lean they are running it haha

[TUFSIG]

I can recommend some tuners that have worked with astrons if they are messing you around

your telling me pete,blame it on the carby i took it for a drive today when i was there.stopped and took off in first then cracked second,pretty much skated till i backed off,so i guess thats a good sign.. its just running like crap on idle?

yeah this is the last time im going to maztech man,they seriously keep blaming someone else and dont want to take no resposability for anything whatsoever? tomorrow its getting out of there no matter what!

if it is your plugs I would be worried about how lean they are running it haha

yeah i thought that aswell,but he said that all the flooding and trying to get the thing started might have fucked the plugs? they took them out though and they seem to be fine?? they kept asking me coz of changed the plugs in which they first put in there,what plugs did we have in it before?? they had normal ngk and i put better denso plugs instead and still they reckon there no good??f@#ke if i know?

cheers for that bro,once i take it out of maztech tomorrow and its still running like crap on idle ill give you a buzz? please tell me your not talking about chris at dalton?

just thought id add,before when i was at maztech i failed to notice the dyno sheet laying there on the passenger floor.my first power figures that anthony told me over the phone were 187.8 kw on 10psi,which i now know was actually wrong??the genuine power figures to my suprise are 194.0 kw on 12psi..and that was some bloody good news for a change ,still doesnt deter the fact that its running like crap on idle?

[turbosigma]

What size/brand injectors are you running? - Maybe to big at idle.

[ISKA8]

yeah there series 8 rx7 injectors,i think there slight overkill but i guess they work??

[ISKA8]

finally got my baby back..she is running like it should be ' perfect '....tomorrow i will start puting it back together.ill post pics up as i go along!
took it for another test drive up the road and man she boogies,compared to when it was a stocker,its a bloody rocket

[geezer101]

Finally! Good news dude. Did someone tell you what was causing the crap idle?

[A112H]

+1 what was the verdict??

[GLANT]

Finally! Good news dude. Did someone tell you what was causing the crap idle?

maztech caused it

[GLANT]

harry...could it be as simple as dirty injectors ,fuel lines etc??? youve had the beast apart for a bit...maybe check them??

not that bro,me and a freind cleaned up a;ll the lines before putting the motor in..

Finally! Good news dude. Did someone tell you what was causing the crap idle?

maztech caused it

your a funny c@#t..nah wasnt that either...

+1 what was the verdict??

ok found out the injector plugs(wires were pushed back everytime we plug them in).and also the plugs needed changing..
now she bpurring like a kitten

[ISKA8]

here are some more pics of the car getting put back together...
2pack mirrors back on..

bonnet painted...
spoiler,bars ready for fitment..
all the moulds..

[ISKA8]

more of the parts getting put on the car....


a little more good news for me,took the car for a good trashing today to see how much better it really is..noticed that the boost gauge is reading about 7 or 8 psi ?? i thought the gauge was faulty but i put another one in and the same thing? i called maztech and asked them how much boost did they really run on the car and what boost gauge were they readind when it was getting dynoed?they told me it was running 12psi but my car isnt hitting that range at all?i think while playing around in the engine bay i might have accidentaly touched the boost controller and brought the boost down? im gonna turn up the boost tomorrow and see how she goes..
the car is turning the wheels no worries in second gear but i just want to see how much more she has..

[geezer101]

Be gentle, you're going to be the first in line to feel pissed off if it goes boom! Good that you've got it back running properly though...

[A112H]

Super slick, very nice job mate

yeah im not giving her that much of a hard time

Super slick, very nice job mate

cheers jason..she is 98% complete and running like a dream!

[ISKA8]

just a quick question? does anyone know were i can buy a fuel sender? my petrol gauge isnt working and i assume its the sender..ive called bursons and repco but they dont stock anything? i was told to test if its the sender,to connect positive to one of the earth wires from the existing sender,connect them to the gauge and see if it reads full tank,then its the sender? correct? is there another way to test if that infact is the issue?

[geezer101]

You got a multi meter? If not you can pick up a cheap digital one for under $15. Set it for ohms (resistance) and check the gauge from the back of the instrument panel (when you're testing for resistance the meter isn't sensitive to polarity so it won't matter which way you hook it up)- if it shows no reading then the internal circuit is broken. Unplug your sender and do the same. Don't try to do it with either unit plugged in or it'll try to read the whole circuit. If they check out o.k, then there's a fault somewhere in the wiring loom.

[turbogj260]

if you disconnect the sender it should read either full or empty, if you earth out the sender wire it will do the opposite. If it moves the gauge is ok, Sounds like the sender is cactus. Second hand is usually the only option unfortunately. DONT PUT POWER ON THE SENDER WIRE!

[ISKA8]

thanks for the onfo guys,ive been flatout at work so i havnt had a chance to work on the car yet..i will get to it asap and let you guys know what was the problem..
i think its the sender aswell?

Second hand is usually the only option unfortunately.

bloody hell,why cant you get them brand new? id be sh@#t outta luck if the secondhand one i buy is crap aswell

[Superscan811]

Basically the fuel sender is just a wire wound potentiometer.

The wire can wear out but in most of the cases I've come across:

1. The float is stuffed.
Solution: Grab a new/second hand float and install it.

2. The pivot holes or the piece of bent wire the float is attached to have worn so the "wiper" doesn't touch properly.
Solution: Repair the holes OR bend the wiper in a bit so it "VERY LIGHTLY" rubs all the way along the wire windings.

Cheers.

[turbogj260]

Ive got few of the wound wire cards but as stated it sounds like the pivot holes are worn and the metal piece that rubs on the wound wire card isnt touching in certain spot or spots. When you pull it out you will c what we are talking about. If you get stuck flick me a PM and next time i go to upull it ill grab you a good one if i can find it...

cheers for that jason..pretty much make sensce now

[astronturbo77]

yeah there series 8 rx7 injectors,i think there slight overkill but i guess they work??

no way, from series 5 onwards are side feed type, most likely they are series 5 turbo items
