hey guys i recently askd for help because of my engine running poor and misfiring under light throttle well it got worse to the point were i couldnt drive the car and on cold start it would stall sunday me and my brother took apart the airflow meters (sprayed with light break cleaner spray) and pulled out my coil packs on sparkplugs my sparkplugs werent bogged they where not the bad but my coil packs i have found to be original and never changed the recent owner has taped the bottom of the coil with electrical tape saying that they must have cracks so for the mean time i retaped the coils and clean the plugs and AFMS, started the car and it ran BEAUTIFULLY not a miss, idled smooth and didnt hunt, i drove it for about 45 minutes giving it some gas here and there and then after it really warmed up the miss came back but slightly and so did the hunting, so on the list of thinhgs i need it will be brand new AFMS, and i think its the HKS pod filters that are shitttt so im changing to duel feed apexi and going genuine coilpacks and new plugs that should do the trick,.... now i have a HKS EVC put it by recent owner set at .7 or .9 and when its turned on neither settings actually control the boost it hits about 1.1 bar at full boost when i have it set to .7 and even when its turned of the stock WG it spikes to 1.1. Sometimes it actually works and the boost doesnt go past .7 or .9 but most of the time it doesnt work and it spikes, there is a exhaust leak but im not to sure how far up its coming from, if you put ur ear to the back passenger side of the car u can hear the poppping noise, maybe TURBO gasket? or manifold gasket? i dunno if its common for them to leak? or mayb after market exhaust system has a leak im not to sure but would that cause the spike or for the car to run like shit when really warm? thats all ive found so far,, following are the mods HKS EVC HKS TURBO TIMER 3INCH EXHAUST STAINLESS STEEL HKF POD FILTERS

ok sweet car has done 107000kms the recent owner changed the timing belt and the sparkplugs? also one more issue i just remembered, these brembo brakes are meant to brake pretty hard i imagine? well on this car i have 10.5 inch rims all round with 275 tires and when braking it doesnt have a stop it just continues to slow down like some sort of brake fade? example when going about 30-40kms and u hit the brake hard i imagine it should stop on the spot? well it just slows down it doesnt just have that hard braking power, recent owner said he changed the pads without machining disc i imagine these are throw out disc can only be used once? well im not sure but for a gtr im sure if u hit the brake as hard as u can the car should come to a quick stop? this one doesnt

hye guys just purchased my 1996 series 2 r33 gtr vspec, im new to the nissans as i had a supra and know all about the 2jz but nothing about the rb26 lol so my car is white its a vspec following mods are 3inch exhaust blitz hks boost controller hks turbo timer hks pod filters boost setup from .7 to .9 ok now the problems im starting to see are the folwing 1)when you start the car after its already warmed up it starts and then drops dramatically in idle to about 2-300rpm hunts between there for 3-5seconds and then idles up at 900rpm sometimes its revs up between 900 - 1100rpm back and forth hunting and then when driven seems to be fine, the boost hold at .7 or .9 so i dont think a boost leak? but when its in vacuum i can see the needle going up and down a little bit... 2)when going in 1st and 2nd with foot lightly under acceleration it seems to backfire and missfire, and then when going full throttle the car will rev fine and then missfire/backfire through the rpm range and it looks to me like the car doesnt want to go past 5000rpm in 3rd or 4th i really have to push it but boost hold at .9 it seems its running alot rich because ive been told it spits out black smoke when driving and i can actually smell the fuel from the exhaust while driving, then all of a sudden the car starts to go hard and actually pushes and goes fine through the rpm range with no missfires or backfires? any keen to lend a hand???
