Hey guys

I have a r33 skyline it has intercooler,apexi filter, 3inch cat bak exhaust and splitfire coilpacks.

So my problems is that boost is coming on around 2500rpm but not kicking hard till around 5grand. Any ideas what it could be?

Cheers

^^as above. Would you describe it as similar in power to the hard roundhouse kicks Tong Po delivers in the early scenes of the classic Van Damme movie "Kickboxer"?

Specific references needed for comparison to be able to advise further.

Could be tons of stuff. Is the engine running smoothly throughout the rev range? Have you checked the waste gate?

What turbo? What boost control?

If these are too technical questions, you can browse your state's section for a good place to take it (or ask someone to diagnose the car for you).

    • It just occurred to me. The way I am asking for increasing bite as I slow down (ie more bite the more time on the brakes), that is actually sounding like less initial bite, and hence the bite would feel to increase.

    • Sorry, I must've not been clear enough. On my 350GT, the pads originally on the car created dust to high heaven, and did not squeal at any time. I got new low dust pads, that created absolutely NO visible dust, that squealed when cold.  It wasn't  the initial bite, so much as an increase in braking, without extra brake pedal pressure, during a single brake instance. I had to lift off a little as my speed decreased to zero. Loved it! Now on my 370GT, I have to press a little harder as I approach zero. Not hard, just harder. I am too lazy and live in a city block with no room or tools to do it myself, so I would be paying someone to do the switch I looked at the three offerings by Intima, and one of them had a Features line that caught my eye. "Strong initial bite with continual rising coefficient". The problem is that this is on their "Trackday, Time Attack, Sprint" pads, not their day-to-day pads. Its possible that JAX installed track day pads on my 350GT, I just don't know. But I was pretty clear I did not track the car and drove the streets pretty gently. https://intimabrakes.com.au/home-corporate/intima-rr/ I'll send them an email and also check if other pads purport that behaviour.
