R33Turbo

the heck? why is the apexi air flow controller so cheap?? is that apexi super air flow convertor ur talking about isn't it?

Who tuned your car?

I have a turbotech MBC which drops boost off by 3 psi and im not happy with it. I would like to hold the boost at a desired level and im assuming an electronic boost controller will solve this issue. I wanted to know if there were any specific best Electronic boost controllers for GTT R34 or skylines in general. Im thinking maybe go for Greddy ones, as i found one thats $400 and i thought it was REAL CHEAP for an electronic, but then again im abit worried why its so cheap? maybe it can't hold boost long?? I need some advice on which electronic boost controller that holds boost right thru please. and thanks in advanced...

Yes, but then again i keep getting different type of methods from different people to calculate it and it just doesn't work out. Somebody says to deduct 15% off the flywheel figure, which means 206kw becomes 170 kwrw which doesn't make sense. Also because i had a R33 GTS-T previously and know R33 real WELL, by using this method of deducting 15% off 187kw flywheel becomes around 158kwrw which is ALSO IMPOSSIBLE as R33 is around 130-140 and lil over 140 if lucky. Im also aware that R34 is 140-150 kwrw stock but i just wanted to make sure with the experts here. Im actually quite happy with the dyno i made of 158kwrw as its stock, but boost does drop off and its pretty bad when double d clutching as i use the dropped off boost instead of the higher boost in earlier rev range.

will 0.85 be too much of a boost for a stock GTT cooler to take during the australian summer coming if i trash it for the full boost to kick in lil often??? Whats the safest boost to set to 0.8 for summer with stock cooler? i don't wanna waste money on new cooler thats why....

Yeah im aware of that, but all i wanted to do is control the boost at 7-8... My next step is to get all u said but i was thinking maybe i don't need the FMIC for GTT R34 as the intercooler can take up to 200kwrw... But the mechanic told me as it is summer now, it'll be safe to get a FMIC and then boost it up...So would my gtt intercooler be reliable for now with 10 psi boost and exhaust or should i just get a FMIC?

The boost seems to boost up to about 8 for some reason (FULL STOCK CAR), then drops down to about 7 or 6.7 psi near by the end of rev...And this is how the car made 158 kwrw... Does anyone know why the boost is higher than stock 7 psi for GTT R34??? and also does anyone know why the boost drops off when its not even boosted yet... Later i used a turbotech manual boost controller and tried to control at 10 psi, then later it drops down to 7 psi... Would this mean the MBC is at fault? or my turbo is fooked??? ( BTW it made 164 kw@rw with boost controller)

Oh alright thanks manz, SkylinesAustralia is so much better than the previous forum i was always at (Skylinesowners.com) anywayz, wat the dyno graph shows is that my boost drops down 1 psi i think near by the end of rev with stock boost, so i don't understand wat the hecks going on as i thought it should stay at max stock boost 7 psi.

Oh thats great to hear, so its not doing bad at all? But then again, like i said the 2nd stage boost has been eliminated and i don't know whether its solenoid wires has been earthed or anything but will this maybe increase the few kw up to 158? Or do GTT R34 just doesn't have 2nd stage boost like the R33 at all?

I have dynoed my GTT R34 (FULL STOCK), and have made 158 kw at rw... is this below, average or higher than most GTT R34's??? Also, i have no idea why but there is no 2nd stage boost for my GTT R34 and jumps straight up to full standard boost then drops down alittle bit... Is this normal??? Cuz my previous R33 GTS-T always had 2nd stage boost for stock...
