Hi

im pretty new to the whole turbo world.

I have a Series 2 R33 GTST with pod filter, catback exhaust and turbotech boost controller.

I am running 12 psi and decided to perform a modification that was feature in the latest High Performance Imports magazine.

The modification involved cutting out 1 inch of the rubber intake pipe and installing a metal pipe in place of the rubber that was removed. This was done to ensure the rubber pipe stays all the way open during boost. According to HPI under high boost the rubber intake pipe can occassionally suck in on its self during high amounts of boost resulting in lost power.

Anyway.

As i am driving and hold my foot flat to the floor i hit 13psi and the car just backs off all of a sudden it scares the shit outta me.

What have i done??

Is this the wastegate opening??

I know the boost im running isnt safe, but if only hit 13psi twice and the car has lost all power both times. At the moment im trying to drive it on vacuum until my mechanic down tunes the boost to 10psi.

Does anyone know what i have done wrong??

Thanks

You are hitting rich and retard. The ECU richens the fuel mix and retards the timing, so you dont damage the engine. Run 10psi, much safer.

EDIT - beaten to it..

it's not about safe.

it's about airflow.

R33 and over 10psi of airflow on stock ecu = rich and retard which you will feel as a bad missfire/power loss/jerking type thing.

with the FMIC it will be worse.

the air will be cooler therefore more dense which will mean it will cut out at lower revs say about "4500rpm"

you need some sort of ecu controling thing.

Cheap = SAFC

expensive and better = aftermarket programable ECU (Power FC, MICROGUESS, WOLF, etc etc)

i hit R&R the other day for the first time when i installed an tuned my ebc. freaks you out abit hey...ha i run mine on 11psi which i find safe.

yeah, it scared the absolute shit out of me.

I thought they didnt make SAFC's anymore?

might just need to get a second hand one if thats the case.

considering there is metal reinforcing on the rb25 intake pipe as it is you'd have to be running a LOT of boost...

I have seen one do it with only 260rwkw, took ages trying to work it out on the road, but a good tuner shoudl diagnose ti pretty quick on a dyno.

ive found that every s and r series turbo car has the reinforcement inside the intake pipr, its not a steel tube if that what your looking for, its just a spring that winds itself arount the intake pipe

Mate of mine has a drift R32 2 door with a 25 in it and found a major power drop one night at a drift prac.... pulled into the pits and while free revving the engine the intake pipe was sucking closed.... they had a look at the pod air filter which was almost black it was that dirty... blew some compressed air through it and all was sweet again. only making 220 rwkw on 1.1 bar too so power is not so much a factor with the stock intake pipe

hmmm maybe someone took mine out, it had a pod on it when i bought it, definitely nothing in there like a spring.

I might give the steel pipe insert a crack for something to do

    • The fancy pants red shock tower brace is finally incoming from MX5 Mania, getting it shipped from 'Merica has been a long and problematic process, and GWR, the 'Merican supplier will not ship directly to consumers outside of the US, Mania basically had to order a heap of them, the colour choice was silver, or red, and we all know anything red adds 5 killerwasps of dynotorques..... Whilst it does fit over a 2.5, and I've seen a few photos and videos of it being installed and fitting, google also says it might get real close to the FAB9 intake front runner, people in the US says it does fit with the FAB9 intake, except for one person who said it slightly touched.......so there is that.....LOL..... As it seems that I am the first in AU to have this combination of parts there's no local knowledge about fitment, so I'm just a willing guinea pig in this endeavour, I'll cross my fingers and toes and hope for the best In other news, I ordered stuff from China  on the same day I ordered the 23° silicone bend from Victoria, the stuff from China arrived a day ago, the 23° silicone bend is still travelling around Australia thanks to Australia Post, and "may" be here next week
    • Very good news...I contacted Racebox about it last night. My car is a 2016 so remains to be seen if it is compatible, requires a TCU swap, or is impossible.
    • What ECU are you running? This is probably the biggest question. If it's a PowerFC, I'd probably change the ECU and get something newer that will handle the injectors in a nicer way.
    • FYI: Racebox RE7R Custom Tunes Released!   https://goracebox.com/.../2017-infiniti-q50-q60-re7r-tcm...   FOR GEN 2 (21+) VEHICLES, PLEASE SEE NOTE AT BOTTOM See more   But whomever tuned your car is the tuner you should go back to, AMS, Sonictune or BT Tune....
