just bought one tonight... whats a good boost level to run a pretty much stock rb20det??

So did you get the one with the 1mm hole in it? Thats the best one is it?

I have a turbosmart manual boost controller I scored off a mate, are the Turbosmart ones better then the $25 item?

How do they compare next to the Turbosmart item?

Is this type a bleed valve boost controller? Because if it is I would say the ball and spring type would be far better.

A couple of pics installed on my MR2. Not sure if its right but...seems to be spiking. Could be the way i sealed off the stock solenoid lines.

Hey,

I just got my turbotech controller from Mark off of ebay (whitie_bear on ebay) and my controller doesnt have that tiny excess pressure hole drilled in the back like this one does!!!!!

Isnt that going to highly affect the performance of the controller, i have tried to contact Mark but still no reply, im sure he is busy but this is very annoying to me!!!!!!!!!

Are you sure you even brought it from Mark? When I brought mine from him his eBay name was simark87? Mine does not have the hole either and it works very well.

i drilled a 1mm hole in my mbc and i have noticed if i accelerate slowly but still let the engine rev right out boost will slowly climb up to 15-17psi and hold there but if i smash the loud pedal staright to the ground boost will shoot up to 13psi and hold there.

got me confused...

anyway.. mine is set on the GTR to 10psi and its feels pretty good. its something like 9.5 but spiking a little.. full boost earlier..

still waiting for the S14a to come round and install on that :P

also has anyone had an issue with this controller..? eg. overboost dramatically.. clog up..kill turbo? etc?

i've never had an issue with it. it always holds boost perfectly.

there was one stage where i had heaps of lag, but that turned out to be my cat. changed it, problem solved.

i'm still happy with no hole. since there's no lag, and response is super quick, i'm happy to leave it alone.

so how did u find hole vs no hole? did u do the r34 yet?

rather than reading back thru 72 pages, can someone who has already read them let me know if its worth running them on r33 GTR at 19psi?

ive heard of people running 24psi and over on these. so year go for it.. :P prob contact mark first.

      You know how I know I'm getting old? Because I feel this quote jells with me and SAU Forums, ha ha ha. I've gotten lost a few times as I had muscle memory to scroll to where I wanted on my phone and just click, now I'm lost... Ha ha ha     "I used to be with ‘it’, but then they changed what ‘it’ was. Now what I’m with isn’t ‘it’ anymore and what’s ‘it’ seems weird and scary."

      Rb25 into r31/wont idle

      By MBS206 · Posted

      You don't lose spark if your battery isolator isn't wired correctly and the ECU still has power from the alternator.   Car has an epic wiring problem. Sounds like power connected really really badly in places. Possibly a power pin on a ground pin for the ECU, and constant power in locations that should be switched ignition.   It needs someone good at diagnosing electrical, a good multimeter, and someone with the wiring diagrams to match the engine loom that has been put into the car, and wiring diagrams for the body side of things from the car.

      Front tower strut brace options

      By PNM35 · Posted

      Hi folks, what options exist for PNM35 or what models share the same dimensions and fitment for the front top of tower strut brace. I have seen a few options pop up through Google, the Ultra Racing Australia for one. I have seen some eBay ones that claim they fit C34 and M35 but can't find details if to work out if its true. Also found Taiko / TEMA4x4 claim the one type fits: - Nissan Stagea (2-nd gen; M35) 2001 - 2007, - Nissan Skyline (V35, HV35, NV35, V35, PV35) 2001 - 2007 - Infiniti G35, G35X (3-rd gen; V35) 2002 - 2006 But not sure how true that is. Anyone fitted one or know of someone using one and can confirm what does fit?

      AC Compressor

      By Butters · Posted

      I got the full kit.   The compressor as above is much smaller and lighter.  Also quieter. Bracket is visually mint and much lighter. The dryer and heat exchanger(rad) are one unit. Also smaller and lighter.  Much more room for an oil cooler. The fan I got was a bit Meh and I might change it.   And above all else it is more efficient, tested a good 3-4 degree's cooler than the old system, which is a lot. Disclaimer though - It wasn't a back to back test given different days. It really does feel colder though(always).  And this example is in my car with that crusty looking old compressor, not new vs new

      I did not need to see this! With summer quickly approaching... Did you just get the compressor with the bracket or the full kit with fan and everything? In what way is different to the old OEM one?
