Hey guys,

I was deciding on boosting up my car, however Broads (thanks mate!) emailed turbosmart for me with some info, and I emailed another guy who is selling them.

Now, here is the turbosmart reply
"A Boost Tee will be a very cost effective way of controlling boost on the Skyline. Unfortunately with these cars you do get to a point where a boost only modification can have a negative effect on performance. The reason for this is these car have ignition problems and often require new ignition coils to operate any more than a factory boost level, secondly the ECU will pull ignition timing out and put fuel in when boost is raised, this usually means more boost the same power.

We have just released a fuel cut defender product to address this Skyline fueling issue, obviously this is something that needs to be tuned on a dyno. I have attached the instructions for this new product of ours.

Bang for buck a Boost Tee with an FCD-003 fuel cut defender will be a good combo."




and here is the reply from another guy regarding his boost controller which alot of SAU members have bought - and everyone is extremely happy with it.
The question I asked was...

"Hi!
I have heard nothing but great results for your product. My question is, i emailed turbosmart about a T boost controller for my R33GTSt skyline. I want to run 10psi however they said I need an item called a fuel defender or something of the sort and it needs to be dyno tuned because i have a stock ECU meaning that more boost dialed in - the ECU retards timing to save the engine. More boost, more fuel, engine doesnt like it to in the end, more boost, making same power as stock/previous boost level. Honest opinion, would this boost controller work on my car? I am very interested however I do not want to throw more money at it such as dyno turning as I just want to enjoy it on the circut.
Thanks, Chris"

Reply....

"If your running about 10psi, you won't need a fuel cut defender, but what you will need is a boost gauge. My freind has my boost controller on his skyline and he run's 12psi with no mods to the ecu. But if you start going higher in boost then you will need fuel cut defender and ecu mods, because your fuel wont support that boost level, i hope i have been of some help."


what are your thoughts guys?

Bleeder T's are a dirty option I wouldn't trust a bleeder T to hold a set pressure if it spikes and you don't realise it you could destroy your engine.

Profecs are avalible for around $300 new from greenline and nengun, you get better control and things like over boost alarms.

I'd go an electronic boost controller, you pay more but you get more
Also I wouldn't do it until after FMIC

hmm....if I decide to do a FMIC

prob wont though :D

no point in turning up boost in a r33 without fmic you can get better results from a r33 with a stock cooler by winding in more timing than turning up the boost on that tiny lil core.

Anyone thought of the Jaycar alternative. If you're handy with a soldering iron these can be a cheap way to control boost much better than the bleed valve.

I believe they have 64 points for setting the boost curve and they will stop wastgate creep. These are designed to set boost according to engine load.

At around $140 with the hand controller its a bargain option

My mate Shane is running one as well as a Jaycar fuel adjuster.

I wouldn't recommend anything you solder together yourself, but hey, if you don't want to spend much then they might do the job, or get a new hobby.

Is your mate Shane happy with the controller? Is it reliable?

I have a Jaycar IEBC (have had it it for about 6 months) and I'm very happy with it. It takes a bit more effort to set up initially, but it works very well for the price.

I'd say reliability would be very dependent on the soldering ability of the person building the unit.

Is the handcontroller fairly straight forward oggie?

PM him, 'ferret'

As far as I know he's had no problems so far.

Yes, very easy to use. The "fiddly" part is just getting the mapping itself correct. You have to ensure a smooth transition from actuator fully closed to open. If you try to open too it quickly it will spike - too slowly and you aren't getting the best performance.
