R33 Gtr Running 20 Psi - Boost Issues. Video Inside

[drgtr7]

Hks 2530's running 20 psi.

Can't get my car to boost cleanly throughout the gears , and i have no idea why.

When i run 16 psi or 1 bar, no problems. As soon as I flick my eboost street to my other setting (20psi) it does this...

Does anyone have any ideas or solutions? Workshop is telling me that i need new actuators... All pipes are tight, no leaks whatsoever.

Runs like a champ on 16psi, but cant get it to run properly or boost properly on 20 psi. Keeps giving me that flick back

Any feedback or advice greatly appreciated. Cheers

more information required. What ecu? Injectors?

it could be actuators but it seems more like a boost or fuel cut

[drgtr7]

Power fc

Sard 800cc

Bosch 044 fuel pump

Actuators where actually set at 7psi but wasn't making more then 300rwkw, then we adjusted them 16.5 psi. To see the full amount of 365rwkw

[Guilt-Toy]

it could be a missfire.

[drgtr7]

Coil packs maybe?

[hy_rpm]

If it is a miss which sounds like it is

as it only comes on high boost ill try the easy and cheapest solution first

New set of spark plugz gapped to 0.7mm then if there still problems either the coils or wiring but I doubt it

[drgtr7]

Spark plugs have beeb done 2 weeks ago, so I think some new coil packs should be arranged.

Issue might be sorted. Problem is faulty solenoid. Using an mbc now. Will report back later after driving for a full day etc. Feels like it should now when it hits boost

[drgtr7]

Delayed response. But for anyone reading this. It was turbo shuffle. I recommend using standard intake pipes they are good for 350 - 4000 rwkw

[Tommy Kaira RL]

wow 4000rwkw

[drgtr7]

*400 lol

[Blackkers]

so what went wrong? were you running aftermarket intake pipes that were causing a flow restriction or something

[drgtr7]

Yes, I was using hks intake pipes. My turbo's didn't like them. It would cause them to stall/shuffle. Went back to standard got a retune. Never had another issue again.

[GTRPSI]

Khaled, still not reving it?

Just make sure Stefan never drives it. (unless you want to spin a bearing)

[drgtr7]

Hey peter.

Nah still got it capped at 7k and the occasional 7.5. I really want a midrange street car. Hopefully my next retune with e85 should see that. Lol he can drive my car, but then i'll drive his

LOL Thats why im taking my time putting it back together again, cant trust both of you buggers.

the irony that the HKS turbos didn't like the HKS intake pipes...

and all for HKS price too

However, I wouldn't be surprised if it wasn't something tune related that wasn't solved upon the retune?
