hey um basically i am interested in purchasing 1 of these, but what should i get to determine how much boost im cranking..

I dont want to spend $80 just to get a turbo timer/boost gauge unit which tells me my current boost, just so i can adjust the boost controller. I assume the stock boost controller isnt good for this because it only cranks to 7 psi and ive heard that the majority of stockish 32 gts-t owners are running theirs at about 12 PSI.. 12 PSI is about right yeh?

Is there some kind of tool i can hook onto some where that will tell me how much boost im running to help me adjust it???

Thanks

1.) r32 gtst does not have a stock boost controller. the boost is regulated by the spring in the wastegate actuator.

2.) R32 gtst (rb20 powered cars) stock boost is 10psi.

3.) buy a BOOST GAUGE. I suggest VDO brand.

it is simple, black face, white numbers red marker. cost about $40 and is very accurate.

I think you would be surprised by the response you would get in the thread it's actively looked at by a fair few people..

As GTST has said - get a boost gauge and that way you'll know exactly whats going on..

your running a turbo car where you want to adjust the boost of the turbo however you aren't prepared to get a boost gauge.. I think that's a bit silly especially if something bad happens.. bite the bullet they aren't that expensive and in the long run you'll be much happier and maybe save your car some damage..

As for the stock boost gauge does it go to +7 x100 mmHG or whatever it is which i believe is 14psi.. 760 mm Hg = 14.7 psi

-_- no comment

well ive never had a rice car before so i didnt realize you HAD to have a boost gauge. So theres no tool.. I didnt have to buy a electronic pressure gauge to test my compression, i used a mechanical gauge i stuck into each cylinder and turned the engine over to check. I assumed there was a tool, even if its not turbocharger specific that would measure boost or air pressure or whatever, mechanically but, evidently, the only way of doing it is by buying a boost gauge.

And well $80 is alot.. Im not like most of the people on here who spend hundreds of dollars on massive Greddy stickers, neon lights, gianormous rear wings, glow in the dark windscreen wipers and such. I wanted a mechanical boost gauge.. not a electronic one.. That and im 18 so.. Some of arent quite on $50k a year.

Ill take it to a dyno and get them to dyno it up and set up my controller any way seeing as you just cant have a turboed car without a boost gauge and well i dont need more electronics, my car already looks like a food processor.

Listen to these guys and buy a boost gauge! i was in the exact same boat as you and didnt want to spend $$$ on a gauge... however it is an important measuring instrument that will keep you in control of your turbo... I bought a Speco (psi) gauge and its perfect! Cost me $45 from super cheap auto... and then bought an autometer pillar pod for $70 (because it fits perfect) you can get universal ones for $35 from Car Mate in Villawood (Sydney) and fit it on 2hrs without drilling one hole in my a-pillar! And then I fit my Turbotech and adjusted it to perfectly sit on 9psi... you spend more money on petrol per week then what it cost to fit a gauge! thays my 2 cents..

But be careful! Do NOT attempt to raise your boost levels using the factory gauge as an indication.. it is inaccurate and not for fine tuning...

A comprimise would be to do what I did?

Bought a guage, hooked it up, dialled in 7psi on the controller, using the boost guage to confirm, and then I noted where 7psi on the stock guage is. Boost guage is now unplugged, with the hose sitting tied up in the enginebay.

If the controller fails somehow, i'll see the boost go higher than +5000 millimeters of mercury on the stock guage, I know something has happened. If I need to raise the boost, I can easily hook my guage back up again.

I'm not worried about the price of a guage, like you are, i'm worried about the rice-factor of having a big guage in my car! =-p

There in in very risky. The gauge is over 15 years old.

Who's to say it gets further out of calibration in 3-4 months time? 8 months?

You would never know until its potentially too late

Boost could rise 1psi every 6 months and the stock gauge read the same as what it is now.

There would be no way to tell, and you couldnt "feel" the increase as you drive it often.

123456 - For $40, a mechanical gauge is cheap insurance on a turbo car.

I earn a reasonable amount and have done a few reasonable motor builds ups etc.

But even then i couldnt justify $200 for a boost gauge. Its very practical to use a mech one IMO

I like to judge a book by it's cover.

I've decided that from the few posts made by 123456, I will no longer read as it is a shit book.

if you don't get it mate, you are given good advice and come back with stupid, unthoughtful remarks.

Won't bother answering any more of your posts.

I'm sure you will soon ask about fluttering and wether an intercooler is really required or is it rice.

good luck on your skyline

hey gtst, have a cry man ^^ all ive seen you do is flame people its hilarious, dont read my posts, youll be doing me a favour, dont you worry

Shouldnt assume every 1 is a dead sh*t and that you are the most intelligent person on the forums either^^

As for not reading my posts because its a sh*t book, well i find it hilarious that you insult me because of a lack of knowledge, and all the while read 3 page books

Oh well, theres one in every forum and, well, E-Thugs suck =)

Dude you need to chill out because all he has done is offer advice & spoken the truth, and you seem to be unwilling to make an investment on your car.......

My mechanical boost gauge & pod cost about $80. If your going to be that stupid & adjust boost without knowing what it is, a new turbo & maybe a rebuild is going to - here's just a hint - cost more than $80-$100.

So I would suggest one of 2 things - Don't get the boost controller & keep your car the way it is. Or if you get the boost controller, buy a boost gauge & adjust carefully bit by bit. Start with it wound almost all the way out & adjust as necessary.

ohh thx ill go super cheap tomoro check it out

And yeh, rice was a major factor, its rice enough as it is, being a japanese car and all >.<

are you serious? you dont want a boost guage becuase you think its rice??? how about all the v8's out there with guages on the bonnet, do you think thats rice too... or is that differant because there not a jap car, they need to know whats goin on just as much as we do.....

noo the gts bloke, is a asshole to every 1 it seems, 90% of the posts ive read involve him being a wanker but meh, watever, each to his own i dont care. Talking about cars not some random. As for me chilling out well, im not the irate one, or at least wasnt before, youll note that he is attacking first. But meh, dont need to justify anything right?

As for being stupid and adjusting it without knowing etc, if u read my posts youll note that i said id get it professionally adjusted

as for rice, well type "definition of rice" into google, and youll catch my drift

Similar story to Randy here. I connected up a standard air pressure gauge that is accurate (old school mechanial), I used this to set 10psi. Drove round for a while to see it was consistent, then connected up the stock gauge and noted where this was sitting at full boost. I left the hose coming through the firewall but disconnected at the engine bay so can always hook in later.

So I just use the stock gauge, which is fine although not as obvious as an aftermarket one.

I connect up the calibrating gauge every 3 months or so to check boost level is the same but even that is a bit pedantic.

I just want to keep my car as stock looking as possible..

bahahaha ethug..

ok mate.

what can I say, I'm a ricer and am trying to make you one too.

I don't have a short temper nor do I make a habit of flaming people for no reason.

you asked for advice, people answered.

I gave my bit too.

then all you did was give stupid reasons why you thin things are rice or not required.

People need to ask questions to learn. Of course. I did the same.

but when I got an answer, I then didn't argue it.. I may have questioned the reason behind the persons answer but not say that they were wrong.

someone mentioned above that you will be spending like $60 on fuel minimum per week.

50 odd litres of optimax at $1.40 per litre. you work it out.

you don't want rice or expensive, so I suggested you buy VDO brand.

it is the manufacturer that does the factory gauges for MANY MANY cars.

it is simple and doesn't light up fancy or anything.

accurate and plain.

but you still argue that it's rice and not required.

so why should I or others waste their time on someone with a f*kwit attitude like you?

E thug..

if you want me to say it to your face I'll be more than happy to mate.

You should think before you open your mouth occasionally.

it's even ok to type your responce.. but maybe re-read it to make sure people aren't going to think that you are a complete tool.

    • I would again like too thank Matt for his help in me sourcing the detachable hard top for the little red car, without Matt's assistance in inspecting it and locking it down, I can guarantee it would have sold before I could get up to see it,  and as that was the only available NC hardtop in Australia, I consider myself extremely lucky on multiple levels To say I'm more that happy would be an understatement And, it is 100% water tight, I drove through torrential rain coming back south, and by torrential, they type of rain that doing 40kph in a 110kph zone was a real thing, and even then, the standing water on the Hwy was deep enough to throw waves I'm also more than happy that the huge "BEASTS" that Matt calls dogs didn't eat me for lunch, I'm sure the sniffs and licks were more to "taste test" me, over being to friendly Now to work out what colour to get it painted, panel match, or gloss black........first world problems are real
    • Actually I might have figured out. Looks like there is a tab according to google images but it's hidden. Silly me.
    • No clips on this one like the other connector. Only that red tab that I can push slightly up.
    • For any loom connector that has an obvious release that resists pushing far enough to unclip, just spray some silicone lube into it. You might also benefit from using a bent screwdriver or small pick to push in the right place at the right angle.
    • Hey all, I went to try and fix my indicator not canceling, but I couldn't remove the clockspring cable under the column so I could twist that green thin. Anyone know how to remove this cable? I see this red tab but didn't have any luck. I was thinking of unscrewing it but wasn't sure if it would cause issues. I did notice for my indicator stalk, 2 out of 3 cables were plugged in but the last cable wouldn't fit in the stalk. I'm getting it's for fog lights. It was like this when I originally pulled it off.
