For it to be closed loop it will need a signal input from the camshaft position sensor that you will need to install. You can't just use RPM as an input for closed loop as it's unrelated to what you are adjusting

I thought he was talking about open loop control, but yes if closed loop you obviously need an input as well.

We are looking into an rpm box for you guys.

I've been using the msd rpm switch for a while now... sturdy bit of gear.

I'm suuuper keen to get a hold of 25 VCT conversion parts and camshaft from you once it's all sorted. I'm suprised no one has developed it yet???

Do greddy still make the adjustable cam sprockets for the 25 vct cam gear?

sign me up-

I'll look into that thanks.

The factory RB25 inlet gear is adjustable....it's just on the back of the gear :(

I have seen someone do a bolt configuration through the gear so it was adjustable from the front.

The MSD RPM switch looks like it only turns something on at a specific RPM? We need to turn it off again at a certain RPM so that means it would need to be programmable

Look for a MSD RPM window switch, a RPM Switch is on... A window switch is on and then off :)

I'm just using a on switch mind you, works fine

They seem to be what we were looking for. And only about $150 so also the right price.

what intercooler, are you running??

His car has the basc 70mm ARC GTR intercooler. They're a good bit of gear. Light, good flow and good cooling. They are actually lighter than a stock GTR intercooler!

i was pointing more at v8 vvt that run 4 cam sensors

like the bmw's and soon to be nissan v8's

run them as pairs in/in ex/ex not often you want different valve timing event between left and right banks.

Woudn't trust a eboost to switch anything on, they are a POS at the best of times

cheers

Mines works great, what is the issue you have with them?

Controls boost well, window switch works great, lots of people recommend them?

I've never had problems with the unit or the solenoids on, only the people who wire them in incorrectly. I'd say most people's grief would be caused by the same thing

They have a bad habit of just locking up , outputs stop working at same time and you have to send them back and get them updated.Eboost 1 and 2 do it. ... I am not the only

one who had that problem, a mate had the same problem , and if you look around, a lot of the sport compact racers have had the same problem

Its actually quite common and a lot of workshops won't use them for that reason, as i found out after mine f**ked up.

Not good when its hooked up to your water injection solenoid that for sure

I wound't buy a second handy of ebay, thats for sure!

When it worked it did do a awesome job of boost control, funnily enough mine got stolen out of my car when some work was getting done to it, before i had a chance

to get it updated, hopefully it blows the thiefs car up ..lol

cheers

i've got 2530's, which are almost identical, and with baby cams still managed 400rwkw with E85, only 21psi as well - most people run 260 cams, and prob more around 24psi is the pistons/everything else can take it, you'll walk in the 400 with -5's :)

      Potential MAP Reference Point

      By joshuaho96 · Posted

      Isn't there a fitting on the back of the balance tube? That's what the OEM boost gauge uses.

      Potential MAP Reference Point

      By GTSBoy · Posted

      Getting a decent signal from all 6 throats is a challenge. I don't know for sure, but I suspect that the stock balance tube is not ideal for it. I have done it on an ALFA 4 cylinder (about 35 years ago, so don't ask for too many details). We drilled 4x holes in the manifold runners, put in some fittings and ran hoses to a decent sized (I think it was about 20mm diameter) pipe that ran the length of the inlet manifold. So, it was quite a decent volume. There is a "tuning" balance to be found between the volume of the common plenum on such a thing and the diameter of the pipes running from it to the runners. You need the volume to be large enough to damp out the sharp spikes in pressure signal you get as each runner gets sucked on by its cylinder, but not so large that it becomes too slow to respond to actual changes in MAP. And you need the hoses to be small enough to transmit the signal quickly, but not so small that they delay the signal. You might have to have more than one go at it, if there isn't any actual success based wisdom to be had here. Hopefully there is. Anyway, I would not do it on only a couple of cylinders. I would also not care about "permanently modifying a part". Just bloody drill holes and make stuff better. There is nothing sacred about any GTR unless it is a genuine museum piece that you shouldn't be modifying at all anyway.

      R34 GTT front hood lip

      By Kinkstaah · Posted

      The strange thing is this is a URAS front bumper (or clone of it). The bumper actually does not sit flush with the GTT hood - You need the addon to make the hood 'long' enough to reach the bumper. I have no idea why they didn't incorporate this piece into the bumper itself.. instead of sticking it to the hood instead.

      R34 GTT front hood lip

      By AdiR34 · Posted

      Another thought on this OLD topic: When you paint your bonnet lip, leave a small unpainted back lip/line along the back of the lip, where it rests on the bumper. That way, the line in the back is much more prominent than the gaps in the front/under the lip - and it breaks the hood-to-bumper connection at the "correct" place, when comparing to a GTR. I'm gonna do this with mine this week, so stay tuned for pics!
