Hey i need help with my r33 gtst
I bought it like a month ago. when i first bought it it was running smooth and good
the only problem it had was blocked radiator (i didnt figure it out for a little while)so it over heated if you gave it a bit but it was fine if you didnt give it any.
since then i got my mechanic (who is a really close mate of mine also) to give it a service, gear box fluid, diff fluid, engine oil and oil filter change radiator flush, with all the best raceing/synthectic fluids that are used in the evo 9s and 10s
artfter that It still had a miss at around 5,000 rpm wich got worse becuse i didnt get the spark plugs done stright away didnt realise how much platinum plugs were. (used to have a ford and there $2 a plug)
so last weekend i got off my ass and took my radtiator to nat rad and got them to clean the cores and replace the tanks in the radiator and i also did the spark plugs.
it ran fine for like a day maybe like 80% 90% pulling no over heating and still hasnt even on a hot day full giveing it to trying to make it over heat it was barely sitting on halfway in the hottest part of the day. then i realised i had filled the radiator with pure concentrate radiator fluid. so i flushed it again like yesterday or the day before and mixed it with water and i put it back in.
now its missing again and its getting worse but its still not over heating:)
im thinking its a fuel pump or filter - my mate did test the fuel lines and filter he said seemd good ie not blocked. my mate thinks the fuel filter is good. he is just to busy to check the fuel filter amps and pressure, id test thes amps my self but my muilti meter broke. and i dont know how to or have the tools to test the fuel pressure.
the other thing i think it could be is and so does he is a cracked head/f**ked head (i hope not) i have checked the radiator for oil and the dipstick and oil filler cap/head for coolant and every thing seemd fine everthing where it should be. i havent done a compression test (havent been able to get the tools) and my mate has been to busy.
Is there any mechainics or someone who knows enough about skylines that i can get to just take a look for me and give me a defenate answer?
cause i don't wanna bother buying a new fuel pump if its a cracked head id rather save my money and get a rb26 front cut.
thanks in advance for any help or suggestions
