bit dissapointed.

32 GTR

1st up quick list of mods

rebuilt motor

JE pistons

standard crank and rods every thing else replaced.

To4z a/r 1 rear .70 front

50mm ebay wastegate with 12psi spring

hybrid boost controller electronic

PWR cooler

3.5inch exhaust

power FC

put it on the dyno today to raise the boost from 19 to 25psi

had 403kw.

my boost controller won't go higher than 22.5psi. its maxed out wont turn any more.

my question is should i spend the money on an e boost 2 like my tuner reccomends or will a stiffer wastegate spring do the job?

thanks

Why are you using a cheap Hybrid boost controller on a car which this amount of work?

ditto on the ebay WG ..

if you want more boost

always try to get the WG's spring as close to the desired "low boost" setting you want, and that shouldn't be far from your MAX boost either ..

allows for the best form of boost control. get a better WG and spring and you wont need a boost controller.

yeah i know. i bought it for my old r31 with rb25det. but couldnt fit it.

then i bought the GTR and it had a greddy profec but it didnt work.

so i had this lying around and put it in.

i was going to have 19psi low boost for street and 25psi hi boost for dyno and drag days.

i thought you couldnt get springs rates this high??

where do i get them?

just bought a new tial external gate

has 1.2 Bar springs in it .

Expensive???

i just want the spring.

swap?

haha

just joshin

hoping that an eboost 2 will keep the gate shut .

had a couple of inconsistant ramp ups on the dyno, varied from 380kw to 420kw on 22.5psi. depending on when the gate would open

same thing my ebay one was/is doing, hence the upgrade to tial 38mm

i payed around $500 for brand new tial 38mm.. not sure if that would be big enough for you, think it would. that was with the the 1.2 bar sping .. so 18psi - actually runs 2 springs for that pressure

i posted a thread about sizing etc

here it is

aaron @ sliding performance - slide on the forums is who i got it from, ask him if he can get the springs for you

Hybrid is a cheap boost controller? HAH you’re joking right? Its one of the best I’ve seen. Had a comparison on a dyno with apexi, greaddy even that Greaddy one with the screen and remote ect... None of them held the boost as good as the hybrid EBC... Hybrid held it perfectly steady with NO spike or imperfection on the graph and came on boost very quick, others came on boost late and build boost gradually and had little boost spikes. I don't know where you’re getting your sources about a Hybrid EBC because I’ve seen proof on a dyno my self.

I would suggest a stronger actuator sprig like everyone else would say. Personally I wouldn’t go with e boost.

Just my 5c...

Cheers,

Alex.

i'd say why an ebay wastegate :yes:

which is the lesser of two evils i dont know... they are both equally as sour as the other

just pull the spring out and stretch it!

You have got to be joking?

Anyway, if your running a 12psi spring, and trying to bleed off to more than 22psi.

Thats madness.

Buy a wastegate that works, boost control is one of the most important things and you go to ebay...

Once you get a proven performance application item, get the gate loading as close as you can to the target boost... ie, you wanna run 24psi.

So simply get springs to 21psi (one 14psi + one 7psi) and then bleed the 3psi off that.

Was it on a 400rwkw performance application?

Or a stock turbo'd skyline...

i reckon i know which is more likely

Have you even seen a Hybrid EBC ??

Not quite 400 but over 300. Catharine Caliro (Drift Cat) has one. Seen it on the dyno my self. I was there while it was getting tuned...

A boost controller has nothing to do with the amount of power the car is making. It only controls the boost pressure its quite simple. It regulates the amount of air passing thru to the actuator / waste gate its nothing to technical. And 25psi is not a great deal of boost for any EBC. I don't think I need to explain my self anymore this is common sense guys.

I just don't like people falsely rating Hybrid EBS's...

Alex.

This is how one looks like...

Hybrid use's the same solenoid as Haltech boost controllers and I think e boost might use the same one.

The rest of it speaks for it self. Don't judge if you haven't tried :no:

Just my 5c...

FULL LIST OF SPECS ARE BELOW....

* In cabin adjustment for high boost and low boost.

* Overboost Feature - Hook up an external switch for adding 10% more extra boost.

Ideal for take off in low boost to reduce wheel spin, switch to high boost after you get traction then turn on the over boost function before the finish line!

Easy to install instructions are included. Very compact in size, so you can install it virtually anywhere in the cabin.

This popular product is the result of constant refinement on the street and track.

Well I know my AVCR spikes like a bitch.... Especially in higher gears

As does the one in my friends car. This is after absolutely ages spent adjusting the duty cycle, response time on the solenoid per gear etc etc before anyone asks me if I tried changing the settings.

Its not the worst controler in the world but I definately would not buy another one. In fact if I could be stuffed hauling it out and selling it and installing a new one would not be in the car anymore!

50mm ebay wastegate with 12psi spring

my boost controller won't go higher than 22.5psi. its maxed out wont turn any more.

Regardless of what EBC you are using, you are bleeding off 10 psi which is simply too much.

Get a wastegate spring for the minimum boost you are likely to run.

My rule of thumb is never to bleed off more than 25%

For example if you have a 20 psi then + 25% = 25 psi

:( cheers :P

PS; I don't believe in high/low boost settings, if I want a lower power ouput I don't push the pedal down as far.

      How "plug and play" is the Haltech Pro for R33 GTST

      By GTSBoy · Posted

      Yes, while being... strictly unnecessary. Tuning is a bit like quantum physics. You don't need to understand what Schroedinger's equation actually means. You just need to run the computation and accept the answers. With tuning, you just push page up/down until the exhaust tells you that you've got the fuel right. The VE can stay hidden behind the curtain like the Wizard of Oz and you'll never need to know what he looked like.

      The second part yes, the first part about easy VE calculation is something I've seen a few people talk about online.

      You 100% could do that, would save money on a gym membership lol. But yeah, getting a cordless orbital sander will feel priceless coming from doing it manually.  Good luck with it mate

      I initially was going to do the whole car with a block then realised, it would be a bigger monster of the job 😂 I guess that's all part of the learning process. I appreciate all that advice, I think I got a good idea on how to tackle this whole job.

      By Murray_Calavera · Posted

      I admire your efforts with the scuff pad.  As a mere mortal, I use this for the baulk of my sanding work- https://sydneytools.com.au/product/milwaukee-m18bos125-0-18v-li-ion-cordless-125mm-5-random-orbital-sander-skin-only Yes you can easily create a low spot while sanding. There are 2 types of filler, 1 part of 2 part. The 2 part filler will get used for large corrections and the 1 part filler will get used for pin holes and areas that only need slight filling.  Depending on how zealous you are with the sander (very easy to do with a power tool) or if you are chasing rust etc, yes those low spots will need to get filled or you will end up with a very obvious defects in the paint.  Using the guide coat and large sanding block, high and low areas will be revealed (watch youtube videos for a good visual on this). Its up to you if you think its worth the effort to make the car completely flat before you spray it (you make it flat by filling the low areas).  At the end of the day, it comes down to time. The end result comes from the level of prep put in to the car. If you want a perfect result, you have to put in the time during the prep stage or else it will be impossible to achieve a perfect result during the spraying process.
