hey, i just put on a gfb boost controler (best $70 that i have ever spent as it holds the boost alot better than my previous turbosmart bleed and doesnt spike as much)

Im 97% sure its set up correctly, but im getting like what would happen if you hit the rev limiter? - thats the best discription i could give...

is this a fuel cut or will i need better spark plugs as the boost is blowing the sparks out?

any one else had this problem? or kno what wrong?

thanks guys.

:)

i raced a s2 r33 lastnight and was dead even, and i had that possible fuel cut. if i fixed this problem id chop him. in my lil s1 33.
Their is no difference, it all comes down to mods and the driver.

Dont race... and if you do.... dont post it.....

As previously stated many times before....

Question "Why are you running a $70 part in a $15,000+ car"????

Do it properlly, buy an elecronic boost controller and fuel cut defender.....

Also i hope you have an exhaust and front mount... 11psi is the absolute max you should run on a stock setup...

Ppl's,

I had a problem this morning with my R33 96 S2, i have had it for a couple of days. It has a FMIC, exhuast, BOV, POD & running at 11psi (so they say).

I have given it a bit through 2nd & 3rd gear, but this morning i was in 4th@60-70kph & when i accelerated and it hit boost, it cut out, is this the boost cut.

Just dont see why i did not get this problem in 2nd or 3rd gear.

Any idea's.

PS, i dont know how they are making it do 11psi, no EBC or adjustable T piece in the engine bay, but i was told it hit 12-13 psi when it was dynoed.

PROBLEM SLOVED!!!!!!! :headspin:

i did my homework on this problem and found that it was misfire... ( The extra boost blows out the spark before combustion ) As the stock sparkies are only set up for stock boost. When looking through my lil bros hot4's mags i found a 3page article on sparkplugs. Regapping your plugs from 1.1 (stock) to 0.8 should fix this problem. AND DID MINE :headspin:

There is a cheep way to fix this if your on a budget and a expencive way. i chose the expencive way...

CHEEP WAY.

Go to your local hardware store and get a spark plug gapping tool. Not sure what they are called but they tell you what size your gap is.

Pull your plugs out and tap the tip on a hard surface, then with your new gapping tool ajust it to 0.8, put your sparkies back in, up tha boost n take it 4 a spin.

You can get aftermarket 0.8 pre gapped plugs from autobahn for under $5ea.

EXPENCIVE WAY.

I got the NGK Iridium ix plugs. I payd $20 each and that was with a discount. but if you have future plans of upping the boost above 13psi these pluge are recomended.

as the 6 type stay colder... ive heard ov ppl uping there boost that hard that there sparkies golw red and ignite the fule with out a spark.. trust me you dont want this to happen. you can even go 7 but thats only recomended for over 2bar.

Iridium plugs stay cleaner then your average plugs and are anit-oxidation and anti-corrosion, they apparently last forever too. :headspin:

these plugs are gapped to 0.8 already so you dont have to fcuk around trying to get the correct gap size.

Mad free advertising for NGK...

I :ghost: If you have ever changed your plugs (skyline owners) youl know that its a mission :ghost: took me and a mate well over an hour :ghost:

Do your homework before you go out and spend hundreds of $$ on plugs, but in my oppinion its better than a dead rb25. and well worth it.

Thanks Gamatron ;)

I will check out the gaps on my skyline, i had a R33 S1, that was boosted too 10psi running the stock plugs & it was fine but i did end up changing them too NGK Iridiums.

    • Order for the 2025 model R35 GT-R were accepted from 3rd March and 26th August the last order rolled off the production line at the Tochigi plant. Concerning the R35 GT-R replacement, current Nissan CEO Ivan Espinosa said "Nothing has been decided about the GT-R at this time, but we are well aware that everyone is waiting. The GT-R will evolve and reappear in the future. Please be patient until that day comes." Nissan has a lot of issues with management and finances so take Espinosa's words with a big grain of salt. From what discussions I've had and read about here in Japan, not a lot of people are confident about Nissan's future, let alone the next GT-R. 
    • Thanks. We getting some parts along too so he will be solving the speed issue like next week so i will let you know what he came up with.   
    • 21 is explicitly the coils detected as the issue. Is it guaranteed the actual issue? No. Just the ECU thinks it is. When you say rattling, describe it better, get an audio clip as best you can if possible.
    • Yea got me coppers. Bad news is I just put them in and the car still has the light and shakes. I also noticed I hear like rattling coming from the exhaust piping right under me. Does 21 also have a possibility of being O2 sensors?   So, coil packs are good, the harness is good, the MAF is working, and obviously the spark plugs just replaced and working.
    • Make sure you drop the GTT base tune back in, and set your injectors again, this will remove anything playing up with it you may have removed. Possibly lean there as it's normally a fast transient going THROUGH atmospheric pressure, and a turbo motor would then quickly go richer as boost builds. The only worry you MIGHT have is ignition timing, as the DE is higher compression than the DET from memory. But again, you're not in boost, so the DE motor will be a lot more forgiving at atmospheric.   Get Murray, Kinkstahs, and Johnny's input on tuning haltechs, those guys have played with tuning enough in the past to be able to help now you're past the trouble shooting stage of the MAP issue
