Hi Guys,

I have just bought my first R33. Yesturday the rubber pipe broke off from the boost controll and my boost was hiting (whats looks to be) 5 on the in dash display. before i this happened the boost was only getting up too 1-2 on the display. What is the standard boost the car should run. I have also been told not to boost the stock turbos as the fins with break. :P..

The car has a boost controller but its turned all the way down.

How much would a after market turbo cost?

Thanks for the help,

Kyle

Hey buddy

Stock boost is about 7psi.

Have a read through the forced induction section of the forum, you will find heaps more info there :P

You can boost the stock turbos up to no more than 14psi which is what is recommended, but thats with supporting modifications such as FMIC and turbo back exhaust.

It should run on or around that line between 0-7, and a turbo upgrade can cost from 1-5k for something good!

I think high flow'd turbo's are around $1700 all up, but there not gonna do you any good with the stock ecu.

Thanks guys, its a good place to start. how much would a good turn cost, I was speaking to a guy on the Gold Coast and he said he spent arund $700 for a dyno turn,

What does FMIC stand for, Sorry for the stupid questions but im new and its the best way to learn. lol

Where could i find instruction on how to hock up a boost gague.

Thanks in advance.

You'll need either a piggyback ecu or replacement ecu to be able to "tune" anything at all. Otherwise the most you'll be able to do is adjust ignition timing which is hardly worth paying that much money for.

A good dyno tune will normally cost around a minimum of $150 just for the tune. The $700 you mentioned would have included extra stuff, and maybe tuning more than one thing. I've only had a Apexi SAFC piggyback tuned which isn't that hard so cant give you a good estimate for say a full replacement ecu sorry.

FMIC is Front Mount InterCooler. You should be able to find some good info on these forums by using the search button... :P

there is a small nozzle on the back right hand side of the engine (if you're facing forwards, or left if you're at the front of the car looking in the engine bay) - it has a small rubber thing on it to block it off - you just remove the rubber stop and connect your boost guage hose to that nozzle. as for mounting it etc. well thats a bit more difficult and entirely up to you...

generally, if you're not sure, get a friend or workshop to do it...I'm kinda in the same boat as far as my technical ability. I know how to do fairly simple stuff but I'm no mechanic. :(

Oh, and stock boost is 5psi up to 4500rpm where it increases to ~7 psi. But if you've replaced the stock boost solenoid with a boost controller you'll probably want to set it anywhere between 7 and 10psi but no higher than 10 to protect the stock turbo. If the turbo shatters (which it will at anything around 14psi) it'll cost more than just a replacement turbo...

Like others have said, to make an aftermarket turbo worthwhile, you'll need to spend around $5K including the turbo itself...and maybe more to get the best from it...

      Use text replace function to auto-link to referred threads?

      By GTSBoy · Posted

      Hi, We've all posted some thread, or know of some other person's thread, that contains information that we want to send people who are asking question to. But if we don't have a link readily available, have to go do a search for the thread before being able to do so. So, it occurred to me that we could possibly utilise the auto-text-replace function that fixes some of my swear words to perhaps auto replace some special keywords with text that also has a link to the thread. A specific example. The thread that I did with the improved R32 GTR wiring diagram scans. If the phrase "R32 GTR wiring diagram" could be auto replaced with "R32 GTR wiring diagram" then all I (or @Duncan, or any of the others that refer to the thread) need to do is remember that that's the keyword (or phrase in this case). OK, it would be better if this keyphrase wasn't that long, but it does need to be specific enough that it doesn't get triggered automatically. And obviously there are threads on turbo topics, or suspension topics that we could treat similarly. Alternatively (and/or additionally), I've been thinking about trying to build a library of the real expert content that is trapped in the bowels of the 25odd years of this site. Things like some of SydneyKid's content. There are threads that he started that should be more easily found, and he has individual posts, or series of posts, in other people's threads, containing very good information. Some of us know that it is there, but....just have no memory of exactly where/when/how we saw it. If we had some sort of library thread, we could put posts in there containing links to things we've found, suggestions for how to categorise it, then a mod or other appointed thread maintainer can copy the link and any key text up into the first post in the library thread. There are probably many other ways to get it done. Some sort of wiki is probably the best way.   Thoughts?

      My thermostat had no gasket?

      By Duncan · Posted

      But, probably that happened to the last person too, which is why the RTV was there.....if you aren't putting a new gasket in you will need to seal the old gasket back to the metal surface with something, the gaskets will generally only work properly for a single use as they set/harden in that shape

      Wiring high beams in IC7 for R32 GTR

      By Duncan · Posted

      I haven't done this as I still use the factory cluster, but I do know the circuits for the flash vs on for hi beam are separate which is likely the issue. The ON runs full power through the switch and the flash uses the relay in the engine bay. I'd hit the wiring diagram per GTSBoy's suggestion
