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...

Cheers,

Alex.

Edited by 217/r33

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:

FULL LIST OF SPECS ARE BELOW....

* In cabin adjustment for high boost and low boost.

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.

    • You just need to remove the compressor housing, not the entire turbo. I would not be drilling and tapping anything with the housing still on anyways. 
    • So, I put my boat on a boat. First of all, I'm going to come out and say it. Why is Tasmania not considered a holy goal, an apex that all road-legal modified cars go to, to experience? This place is an absolute wonderland of titanic proportions. If people are already getting club runs for once in a lifetime 30 person cruises to Tassy then I've never seemed to see it. It is like someone replaced the entire place with an idyllic wonderland for cars, and all of the people living there with paid actors who are kind, humble, and friendly. Dear god. After doing a lap of almost all of the place I've found that it's a great way to find out all of the little things that the car isn't doing quite right and a great way to figure it all out. All in all, I drove for 4 hours a day for a week and nothing broke. I didn't even need to open the engine bay. This is by all means a great success, but it has left me with a list of things to potentially address. I also now have a 3D printed wheel fitment tool which annoyingly hasn't got any threads in it to actually assemble it. I might be able to tape it together to check the sizing I actually want to use, but it'll likely involving pulling the shocks out to properly measure travel at least at the front, and probably raise the car while I'm at it, at least in the rear. I scraped on quite a few things and I'm not sure how else to go about it. I was taking anything with a bump at what felt like 89 degree angles. And address those 10 other tasks. And wash the car. God damn it is dirty. And somehow, the weather was perfect the entire time - And because I was on the top of Mt Wellington it turns out it was very much about to freeze up there. I did something I typically never do and took some photos up there in what must have been -10 and the foggy felt like suspended ice, rather than mere fog. If you own a car in Australia, you owe it to yourself to do it.
    • Damn that was hilarious, and a bit embarrassing for skylines in general 😂 vintage car life ey. That R33 really stomped. Pretty entertaining stuff
    • Hi, I have a r32 gtr transmission. Does any of you guys have an idea how much power it will hold with the billet center plate and stock gearset? At what power level and use did yours brake with or without billet plate? Thanks, Oystein Lovik
    • Saw this replica police car based on a Mitsubishi Starion XX parked next to a 'police box' (it's literally a box) in Hirohata, Himeji City in Hyogo prefecture the other day. It's owned by Morii-san who is a local Mitsubishi Starion enthusiast. According to a local radio station blog post, he always wanted to make a police car himself based on ones he saw in his favourite Manga comics.  As it's illegal to modify a car to look like a police car and drive on the road, Morii-san tried many times to get permission from Aboshi police station headquarters nearby. They refused initially by after they got tired of that they granted him permission. However, the car can only be displayed on private property and obviously can't be registered as long as the police livery is present. The car was completed at a cost of 1.5 million yen (US$ 10,000) in addition to the car cost. A location was chosen outside Hirohata Police box where the car can easily been seen from the street. Morii-san has two other Starion road cars, both widebody GSR-VRs.
