Boost Leak Help

[Blood]

rb20det, gtst r32 auto

When cold, everything seems fine. Boosts and speeds away.. (+6 - +7 on gauge)

once warm/ been running a while. The boost goes up, and you can hear the turbo spooling.

1. It does seem to be a louder spool

2. the car lags majorly when you floor it and sometimes wont even speed away (slowly increases speed) and boost gauge reads high (+6 - +7)

I did install a boosts controller, and have turned it fully off until i fix this prob.

Now i had to remove the intake pipes to/from intercooler to get to the actuator (small) hose.

im 99.99999% sure i have refitted and tightend all clamps. - i even double checked

mainly there when warm, could it be a crack in the manifold / pipes ??

(everyting in the car is fairly stock)

I have sprayed varios connections of the joins with carby-cleaner and it makes no change.

i know its probly an obvious solution, but cant think atm. any thoughts would be good.

- oh, i even had a mate stand next to engine bay however, i cant boost the car enough unless it under load.

Any simple way to find leaks? (it also has stock bov)

Mate you could take it to a tuning shop to get them to do a smoke test. This under very low pressure puts an inert smoke into intake system & will show you if you have a leak somewhere

Isn't +6-+7 really high like 13-14psi? Is this the standard turbo & tuning?

mine was leaking,

i just found out my turbo/manifold bolts were loose...check em...seems pretty common

ok, i think i may have found the prob... maybe

I removed Boost controller, and it peaks at +7 and drops back to +5 ish..

could be cause by boost spike ??? -- or the fact my car it auto ?

it gets up and goes, just seems very laggy from accelerating to car powering away.....

also i am probly comparing this car to my ole series 5 RX7 ..

Is the laggyness normal for an auto to behave this way?
