Well I just installed a Boost gauge and a 2-Stage Turbo Smart controller.

Stock boost was running 5psi and spiking to 6psi between 6000-7500 rpm's.

Now running 10psi low boost, 12psi hi boost with no spike.

The boost seems to come on lower down in the rpm.

I think I have just become a boost freak........what a rush.

BTW a big thanks to 51Jay and Co. for helping me put it in.

So guys, running stock intercooler on the car? Are you getting the big slump in boost around 4-5000RPM like I hear the R33 will do if theres no aftermarket ECU? Or is that only when going over 12PSI?

Hmm... I might go for a quick cheapo boost upgrade while I save up for my FMIC, PFC and AVC-R if the drivability is still good.

Need to get my HiTech exhaust ordered and on there.. stock system is strangling the engine I am sure :)

I've got a blitz dual sbc type s. It electronically controls the level of boost, I've got 2 settings; 0.6 bar and 0.8 bar. I use 0.6 bar for most of my daily driving and especially in the warmer weather as I'm still running the stock cooler (I've got a Trust front mount on its way). I only run 0.8bar mainly at night when its much colder. I cant stress how important it is to back off the engine if you've got it on a high boost setting and you hear detonation (it sounds like something rattling in the engine, like marbles) cos if you keep your foot buried you'll be rebuilding that engine :)

thats what im affraid of and whats keeping me from running more boost on mine as i cant really afford to be rebuilding the engine.

I get my boost guage this week and will also get a bleed valve... i want to run about 9 - 11psi until my GTR FMIC gets here from Japan.

At present the only mods i have are a POD Filter, CAT Back and Re-mapped ECU.

definately take it easy on a hot day... alternatively you can do other things to reduce intake temps (the main thing causing detonation on your setup) by installing a cold air partition for the pod filter

i cant see how anyone would really want to thrash it on a 30degree day, so nice for cruising!

Intake air temp on a hot day on the move is usually around 40-43degrees. Sitting in the staging lanes on Wed night it was running 55-63degrees at the end of the 1/4 mile it was back down to 42 degrees. A bit of a burn out brings it down from around 50-55 to 45

slayer, over 12psi on the stock cooler is bad news. I used to drive around with 10psi without a s-afc, and there was no getting past the slump in power (not boost) at 5000rpm. Some ppl don't have the same problem, though. Seems every R33 ecu reacts differently.

rob77, whats the trust fmic gonna set you back, including fitting and piping?

Unsure yet cos it hasnt landed and the workshop is unsure what price they paid for it. When I ordered it the exchange rate was 1aud to 64yen, when it shipped (about 1.5-2 months later) it was 1aud to 68-69yen. Plus you got GST and import duty. Plus it was there 2nd dearest kit for a R33 gts25t, the dearest one includes a intake plenum so that the return pipes can come up the right hand side of the engine. Just the intake plenum is about $1500.

    • The German place in Cabramatta was rock solid, fresh pretzel cooked to order back then. Then it went all quiet, after all the poker machines were removed, then I believe it closed for good. I did drive past the other week and noticed outdoor lighting a big screen, but no idea what is there now.  
    • Yeah I suspect even if you hold airmass per cycle/cylinder constant if you get too far away from stock you're still going to have problems running the factory tune within the bounds of the factory load scale. Cams, different displacement/rod ratio, etc. I'm just lucky that the GTIII-SS with wastegate boost + CA compliance cats is pretty much equivalent to stock turbos. When I have actual space I can finally get it tuned and modify the fuel system for flex fuel to 100% handle any detonation concerns when cranking the boost to whatever those dinky turbos can put out.
    • I would say no, why, because my daughter, who also lives in Goulburn, hasn't recommended us going there Pity, as we miss all the German joints around in Sydney, actually, the restaurants are the only thing I really miss about Sydney, and a special mention to Ishibanboshi at Bondi Junction, their Kara-age Don is heart cloggingly deliciousness (always added a special boiled egg...or 2) 😋 
    • Does that German restaurant still exist in the old place out the NW end of Goulburn? When I say "out the NW end of"...I am really being vague. It was 1997 when I was last there, and the only point of reference I can recall is that it was on the opposite side of the main drag from the big merino. And when I say "opposite side of the main drag", I don't mean "on the main drag". It was either a couple of streets back from there, or might have even been out in the sticks a bit further. Was an old farm building or mill or somesuch. And when I say "the big merino" I might actually be thinking of a completely different part of town, because I just looked on maps and the big bugger is not where I remembered him to be! The food was good, consisting largely of various German mystery-meat sausage/loaf things and kartofflen.
    • So while the second sentence is completely correct and the whole point of the conversation, the first sentence bears consideration. If this bloke is just hoping to throw big turbos on and drive it around, because there are no helpful facilities at all in his tropical paradise** then he likely has zero chance of even knowing what the TP is on the last column in the stock maps, let alone know whether the ECU is operating anywhere near it or past it. So the point is very very moot. And, per what I said before, at stock boost on those turbos, you may well be off the end of the map. **I'm just back from Vanuatu, so I know exactly what small Pacific nations can be like wrt paradise without requisite facilities. But it's not even that simple. I put a high flow on my car and had to drive it around without a proper tune because of the lack of opportunity*** to put the bigger AFM and injectors into it to allow it to be tuned. I had to turn the boost down to less than I had before, and back off the boost controller's ramp, because it was exploring parts of the map that it didn't drive in before, and really couldn't access for tuning on the dyno either, and so was pinging. It was still well within the last column, because when I first**** set up the Nistune on the Neo I rescaled all axes of the maps to give some more space to explore. ***Family dyno was broken ****This was 13 years ago, and the TIM thing wasn't a thing then and so TP would definitely grow when pushing past the stock tune's limits.
