ye, makes a bit more sense now, no time to post a 1000 word essay though on it all

300rwkw - ext gate, 14psi spring, bleeder

[GTR_Legend]

FMIC, 3" zorst, POD, ex cam gear, profec b spec2, 180rwkw, 9psi, R33 gtst

[mad082]

for 200kw there is no point spending $600 on an electronic one when a $30 one will do pretty much the same thing. the electronic one might hold boost at high rpm a bit better, so you might get another 5hp, but $570 for 5hp seems like a waste of money to me.

i have FMIC, pod, ebay dump, 80mm front pipe, 3" cat, 3.5" cat back, stock ecu, stock turbo, turbotech ($30) controller at 11psi - 204kw.

Forged/rebuilt rb25,custom gt35r,45mm ext wastegate,supersonic bov,fmic,fpr,pod

Made 170kw @ 3-4psi on dyno run in so i am trying to decide which ebc i will get (hence why i am askin these questions)

Electronic is a must for my setup to hold boost, prevent spike etc but which one?

I'd probly say dual stage for gated

Im leaning towards eboost II cos of its functionality and guage like appearance Do you think eboost II is overkill?

Which ebc would you guys get if money wasn't an issue?

17psi 255rwkw Blits SBC ID III...

[Tangles]

Hybrid dual stage EBC

[R31Nismoid]

A EBC is not required to control boost, thats the job of the external wastegate as it wont spike, and it certainly should not spike if correctly setup

[Spook's_Skyline]

approx 200kw standard r33 turbo

powerfc boost controller

LMAO "A EBC is not required to control boost" haha yeh thats why they call them 'boost contollers' and in my case an EBC is the smarter option. Just fixed VVT on car and ran on dyno again - put out well over 185rwkw's at 3-4psi...no way i am riskin a gated controller with my setup and the guys doin my car agree. EBC is the safe option and the option that will push the most out of my car.

"Changing the spring tension in the wastegate actuator can vary the boost pressure. However this method of controlling the maximum boost pressure allows for only fixed changes in boost pressure. Instead of changing the springs, a more effective method of adjusting boost is to alter the amount of pressure going to the wastegate. A Gated Boost Control Valve or an Electronic Boost controller regulates the boost pressure going to the wastegate actuator."

Nismoid is a noob.

i was using the Apexi Avcr boost controller but then changed the ecu to an Autronic so now that has its own boost controller since i didnt want to be changing boost as i drive anyway....

i dont like having just a wastegate spring as the boost control because as i have read and seen my car on the dyno, the wastegate spring if set at 20psi will begin to slightly open at a bit under that so its fully open at 20, meaning that there will be more gases vented when not needed and could have been used to boost up the turbo quicker

mmm autronic...nice choice - bloody expensive but worth every cent. My mate has one on his 10sec mr2.

what mods u got ben?

[2BNVS]

yes it was a bit pricey but comparing how the car performs and the funtions it has over the power fc that used to run its at 2 different ends of the scale

i have an rb25/30, full rebuilt, balanced blueprinted, so basically pretty damn solid block, got 270 degree cams with big lift, trust td07s turbo, custom plenum, fuel system is plenty, autronic sm4 ecu and CDI system

alot more mods but yeh just the main ones anyways

Ha!

My R32 doesnt have a boost controller except for the wastegate, it runs 0.75bar.

60% of the time, it works all of the time.

But go build a Jaycar IEBC and hand controller - cheap AND good - and fun to make. $140 max.

Are you stupid or do you not understand the fundamentals of how a wastegate works and how spring rates affect the operation of the wastegate?

With your statement above you clearly do not have a clear understanding. Thats fine, regurgitating what someone else says most often isnt the best way to learn.

I would really love to see you actully contribute some technical information rather than trying to slander people who do have such information

No, not stupid LOL but its pretty damn funny considering i got that EXACT quote off turbosmarts website and i think those guys have a pretty "CLEAR" understanding of what they are talking about seeings as they make the damn things...if you think your so high and mighty why dont you post up your explanation and we'll see how different it is. HAHA jokes on you nismoid

By the way...just to be a picky noob like yourself, you used "CLEAR" to many times in the one sentence, "you clearly do not have a clear" lol. I think your the stupid one nisMOID.

Tuche - or however you spell it.

Dont wanna hi-jack the thread but just wanna ask a question

i got a pod, FMIC, full zorst and stock turbo on r33 ....but i dont know wat boost controller to get

i heard that the manual bleed valves cause boost spikes on cold days and might over boost???? and dont want to get expensive EBC's

Can any one recommend my a reliable cheap boost controller/bleed valve that wont spike for my mods....wanting to run maybe 12 psi daily

thanks

[mad082]

that is partly to do with where the wastegate is being fed from. if you have the feed coming from the cold side of the intercooler then it will spike much more. ever since changing mine so it fed off the pipe from the turbo to the intercooler it is much more stable.

and of course turbosmart is going to say that a boost controller is better than a higher wastegate pressure spring. they are trying to sell boost controllers. it would be like ford advertising that holden is a better car. but i don't think you understand that statement from the turbosmart website. they say that you can change the boost pressure by changing the wastegate spring. you seem to think otherwise. it is just that you can change the boost while driving, and that they are set increments, like 10,12,14,16,18. you can't wind the boost up by 0.2psi like you can with a EBC.

but having the wastegate open slightly at lower pressure than when it is fully open isn't going to make much difference. if you have full boost by 3500rpm then you may lose 5hp for about 200rpm below 3500rpm. top end is going to be the same.

but having the wastegate pressure as close to the desired pressure before using any boost controller is better anyway. if you are trying to run 16psi and are using a 15psi wastegate and a manual boost controller, it will probably work better than a ebc and a 5psi wastegate, as the most possible boost drop with the manual setup is 1psi. with the ebc its 10psi.

Ok fair enough that you say they are going to try sell boost controllers but hmmm let me think...dont they sell wastegates aswell , there's something for you to ponder 'MAD082' ?...that is their market but i dont think they are gonna wanna be misleading ppl if this information is incorrect (i deal with accc cases) therefore i beleive what they say to be correct and yes I DO UNDERSTAND IT...im not retarded 'MAD082'.

No i dont think otherwise...I KNOW you can adjust boost this way but what im saying is that its less of a f*k around, more accurate and an extremely superior and "EFFECTIVE" means of adjusting and controlling boost. I think you need to re read the whole post mate 'MAD082'. And in my opinion...if there is any horsepower to be gained, why not do it? EBC makes much more sense and is a 21st century approach as opposed to 50 million year old manual waste gate adjustments and the like.

"it will probably work better than a ebc and a 5psi wastegate, as the most possible boost drop with the manual setup is 1psi. with the ebc its 10psi."

Um this sounds like a no brainer but wouldnt it make more sense to run a 16psi wastegate adjustment in this case and then use ebc to get it to within a 100th...therefore obviously being more accurate than manual adjustement. why the hell would you run 5 psi wastegate....of course your going to be out! Just a thought.

Maybe we should just get back to the above questions and close!
