Nissan 200SX Club - South Africa

i just changed the plugs in my sx from an NGK BKR6EY to a BCPR6ES
which i read up was good for the car. i also just put a cone filter+adapter on.
my car is spluttering a bit but only slightly, it didnt do it before and im hoping it goes away....what could this be from? pls help.

What plug gaps are you running?
@ what boost pressure?

at 0.8-1.0Bar i was always happy with BCPR7es plugs gapped to 0.8 - 0.9mm

my car only running at o.6 bar and it has the BCPR6ES-11 which has a 1.1mm gap, which is standard gap.

i wanna increase my boost but have a std ecu system....
how can i do that, just to like 0.8 bar.

just do it shal be fine make your plugs 0.8mm gap will work great

must i take my car to a dyno shop or tuner to increase the boost?
and must i buy new plugs now, how do i make the gap 0.8?
im not sure on all this stuff so just need to make sure

The sputtering is because you have now increased your air flow , the car is running lean, I'd suggest 3 things, Walbro fuel pump, plug gap 0.6, reset ECU so that maf can better adapt to new air flow increase.

If you have a standard T25 turbo, 0.9 is said to be the most relieble boost that turbo can handle, as for going to a dyno, not really nessasary, AFM should be able to adapt after a reset to the new air flow....but a tuner can always set voltage on dyno which would be the best if you can.

No need for new plugs, take them out, use a feuler guage to measure the gap, tap the spark plug bridge slightly against something hard to decrease the gap untill guege is met.

i thought that could be the prob. how much would this cost? and does this mean i need to get new plugs? i just got these ones lol

o ok i see thanx man. its a T28 turbo that i have in now. u think 0.9-1.0 bar will be good? do i take the ecu to a technician to get reset?

Well you don't nessasary need to go for a walbro....but it is the best....you looking anything between R1250-1500 for the fuel pump, you can buy no names that would work, but many people don't trust them, I have never had a isssue though.

The plugs....no need for new ones.

I personally think the t28 will handle 1 bar, many don't, if you can afford it, do the fuel pump and then take it to a good tuner to set up your afm on the dyno to be safe.

sorry for all the q's but i dont have a boost controller or anything so how would i increase the boost.... im new to the game lol

dude please i know you new to this so we dont want you messing up your car

get a boost controller can get a cheap one for 350 but rather spend the money on a electronic one

take the new plugs you just got get a feeler gauge from auto shop
set the fingets to 0.8 gap then tap the bottom of a plug gently until the feeler gauge can be slid in and out smoothly

or just ask the auto shop you got the plugs to show you how

haha thanx man, i also dont wanna mess up my car...would suck ass.
im gonna have a look for some boost controllers now. so all i need to do is shorten the gap. cool, thanx alot guys.
so its boost controller, reset ecu,plug gap 0.6-0.8mm and fuel pump?
