No one know how to, when i am on twin turbo setup?

I want to test all the lines that are used to the turbo system, that should include the vacuum lines.. i have a jspec 2jzgte engine, i have thought of pressure rise from the hose the air filter is attached to.. the boost leak tester i have bought is where you use an air compressor, it have an regulator on it, so i can control how much pressure of air i put in to the engine, there is an air pressure gauge on it too..

Hi I have bought a boost leak tester, but how do i perform a boost leak test on a stock engine, i have done some searching but most are done on a single turbo engine, i have found a couple of threads with stock engine, but there seems to be different ways to do it, sone say to cap of some lines so you dont pressurize the crankcase, so are there some in here that knows how to, and what lines to cap of?? thanks in advance

I have now mountet some new spark plugs, i got a good deal on denso ik22 plugs, but still have a little ignition problem, not as much as before, it did it once today, as it is Iridium plugs, it is advise not to regap them, they come as .032" gap, is it really necessary to gap them down to .027" when i drive 0.8 to 0.9 bar

What Are the diffence between Them and the one i have?

ok, but it is not every time it does it, only sometimes, so it is very hard to diagnose on.. i can do some pulls and i have no misfire or stuttering at all, i have an air/fuel gauge, and i can't see it on that either when i cut out, it feel like a smooth spark blow out, and i happen so fast, then i can do some more pulls with no problems.. i know all electronic are getting old on our cars, i have just fixed my trac control ecu because it was failing dur blown capacitors.. so maybe it can be electronic related.. but is there no outdate on sparks plugs, can just read some say 25.000 mils or 3 years, and mine is 5 years old.. it is something that have come one day to another ..

My terminals are not the Best, but tight.. My coilpacks are around 5 years old, and from superspark, the clips are change too from 5 years ago with superspark cool packs. So the plugs have around 5 years to Them, and 14.000 km.

hi all I have those spark plugs in my bpu supra, running 1 to 1.2 bar, i have notice on my last 3 rides, that the car stuttering under boost over 3800 rpm range, it is not much but you can just feel it.. What is the lifespan on ngk plugs, mine is 5 years old and about 14.000 km.. in my mind they need replacing, so i tried to search to see if there was a lifespan on them, but haven't been able to find some information on them, some say 8 to 10.000 miles, other 25.000 miles, or 3 years. is there a better opportunity than ngk that have a longere lifespan, as i don't drive the car that much as you can see i have only droved 14.000 km in 5years.

I am still in a need of one..

Year i did find dame issue on mine. Is it fixable or dead.

Today when i took the car out for a ride, my Slip cont off turn on, and stayed on, and my button to turn the tracking control on wont turn the light off in the dash, then i let the car sit for a while, and the Slip cont off turned of then i turned on the car, and i could again turn the tracking control on and off, but not for long, about a couple of min after the Slip cont off lit up again on the dash, and i could not turn it of, i know those boxed have some years on them, and have some problems with the capacitors inside the ecu, can this be my problem?? I have read error code on the abs and trac and no codes stored. and only slip cont off lit, the abs light goes out as normal.

I have en supra na, where i am gonna put an turbo setup on it, what is the best turbo setup to that engine what camshaft should i get. the hp range is 500 hp.. i have en w58 gearbox, is that fine to 500 hp, or should i get en r154 box.. i like to get another air intake, and coil packs.. what clutch should i go for?

I have close to 8 full turns. Just need quater of a turn to get full 8 turns when torqued to 130 Nm.

I have an open nut on mine. I am not sure how much longer than stoch they are. I got the longer studs with my 5mm spacer to my old wheels.

I am not sure, but i am almost sure they are 63mm or 65mm studs.. the bolt are hand tight around 7 full turns, and close to 8 full turns except quarter off a turn when torque 130 nm...
