Na +t Update

hey as a few people may no i turboed my na in january, its been in and out of the tunners just fiddling with it,

Anyways the car has been running really well but for a little while it was running really rich so today i though i would check and re-gap my plugs and do a compression test,

1= 140 2=130 3=140 4=140 5=150 6=160, i though that was pretty normal no probs there the second cylender the spark plug gay was a little out i dont know if that could have done anything to make the comp a little lower but ey its not to bad anyways

those compression readings are all over the place are ok, but not great . even disregarding 2nd cylinder, 140-160 is a little too far apart.

i think the 160 was rounded up a little my mate had the gauge, ok well stupid me i was reading around 2 things i may have done wrong, the car wasnt at operating tempreture so i dont know if that changed the restults but its ment to be at opperating tempreture, and when we were doing it we had one of the push in gauges insted of a turn on one and a little bit of air may have escaped we werent being very accurate just wanted to see if anything seemed way out

ok i take that back.. they arent all over the place..

they are decent... although i suspect that they've been rounded off to the nearest 10.

20-25 apart would make me personally unhappy. i'd be aiming for +/- 10.

here's an idea of other peoples:

yeh i think there was a bit of rounding i didnt see the gauge, cars runnings great thou so cant complaine and hey if i blow the rings gives me a reason to rebuild lol, im picking up a daily driver next week so i can afford to have it off the road if something goes wrong

if its running on 6 cylinders,

she'll be right mate.

Did you change injectors?,I have put a stock turbo on my na also & it runs pretty good as well.All I did was bolt on the standard turbo & intercooler & didn't change the computer or injectors & I think the injector might be to small so I would like to get some new ones before I spend money on a tune/remap etc

Does anyone know what size the stock na injectors are.

[linedup33]

the stock na injectors are 270cc while the gtst stock injectors are 370cc
