what about a full Cometic multi layered steel gasket set.

Full set for intake, exhaust, head etc. Cometic Street Pro - http://cgi.ebay.com/ebaymotors/Cometic-Street-Pro-Top-End-Gasket-Kit-R33-RB25-RB25DET-_W0QQcmdZViewItemQQhashZitem3efbaa0556QQitemZ270510196054QQptZMotorsQ5fCarQ5fTruckQ5fPartsQ5fAccessories

no issues then running 18psi, right in the turbo nice-zone :)

same injectors, similar mods, gt3076r IW, chip+piggyback, 250kw@wheels (auto awd)

really an 040 isnt big enough???

mines flowing enough to feed 550cc injectors without a fuel reg or rail pressure bump and Im sure Ive read it can supply larger injectors too.

A fuel pump flows more fuel at a lower fuel pressure. Increasing the fuel pressure above standard will only make the fuel pump run out of flow quicker.

I would put a factory airbox on it with a panel filter.

So you already have the 4bolt dump pipe? That is handy!

Injectors: From my car I can extrapolate that if you want to run 11.5:1 on standard pressure then you'll only get ~250rwkw. If you bump up the pressure a tad and are willing to run to 90% duty then you'll get a bit more, perhaps 280rwkw. So they are borderline, but SHOULD be just enough. They are 450cc btw and allow a lovely idle.

Tune at 1.1bar and be happy - get a hand controller to self adjust the part throttle.

Then buy tyres in bulk.

I disagree with the factory airbox, you will loose a signifant amount of power. Its criminal on a 3076 imo. If you are certain on keeping the factory airbox then at least upgrade the intake piping to 3" metal. Someone on here had one made up and it was quite expensive as it must join the airbox at exactly the right location.

You will gain power with a 3" metal intake and pod (preferably shielded) when above 250rwkw.

See the quoted post above regarding those small injectors. It is criminal using such small injectors on a 3076 turbo, it will limit you. Otherwise, get a smaller turbo. No point having a large turbo running low boost and relatively low power.

Sell your current injectors and upgrade to larger ones, shouldnt be more than a few hundred changeover and then you will never have to worry about it again. You can then allow your turbo to do its thing, even run E85, or up the boost if you do an engine build one day etc etc. Not to mention it is safer to run injectors less than 80% duty cycle. Sell you fuel pressure regulator and put it towards the injector upgrade instead.

I would have to recommend getting at least 600cc injectors if you want to run pump fuel

and larger again if you wish to run E85 as others above have said and you shouldn't have

any trouble with larger injectors with a good tuner. have a look at deatchwerks in america

for larger injectors especially with the current exchange rate.

Whats your radiator like? A Gtst running 300kw makes a bit of heat esp. on a hot day. I'd get it serviced and cleaned [or new whatever you decide]. I'd even consider an oil cooler kit as well.

And you will want a boost controller, a dual solenoid one is the ducks guts.

But your setup is the basis for a lot of fun............

^^^ not essential at the very minute but top recommendation in future.

I would replace your 'cooler core mate, dont worry about the plenum. Browse the ForSale stuff for a Jap-brand second-hand one.

+1 for PFC hand controller!

      Should I use rust converter on this?

      Should I use rust converter on this?

      By PranK · Posted

      One of the first jobs with the E39 is making sure the tailgate stays up. In BMW fashion they made a little cavity under the roof to hide the dampers rather than putting them down the side like everybody else.  As you can see I have these little cavities that house the dampers. When I cleared one out and vacuumed as much crap as I could out of it I noticed a fair bit of rust. The cavity is bone dry, even after all that rain we had only a few days ago so I'm assuming that whatever allowed the moisture in is fixed but I'd like to treat the rust in there.  I was thinking of just blasting it full of rust converter but I didn't know if this would be beneficial considering I can't actually get in there to prep anything.  Maybe there's a better product?  Thanks guys

      Help Understand GTT Boost Setup

      By GTSBoy · Posted

      The stock boost solenoid is just a valve. Power it and it is open. Unpowered, it is closed. When it is closed, there is no boost bleed out through the solenoid back to the inlet. The wastegate sees all the boost pressure, thus you get the wastegate's spring pressure as your boost pressure. 5 psi. When it is open, it lets some boost escape. This causes the static (boost) pressure in the line to the wastegate to be lower than the pressure in the intercooler pipe. There is probably a small restrictor in the solenoid or one of its lines to limit the flow rate of the escaping air, which limits how far the static pressure can fall, which limits the extra boost. The boost has to climb above the original/wastegate setpoint until the wastegate sees 5 psi. You get 7 psi in the intercooler pipework. A manual boost controller is exactly the same setup, just without the ability to change it on-off. It's always set to whatever you set it to. There is a small leak from the boost controller. The more you screw the adjuster in, the more it leaks, the lower the pressure seen at the wastegate and the higher the boost will be. So, yes, your diagrams are correct.

      Help Understand GTT Boost Setup

      By DraftySquash · Posted

      Hi everyone, Apologies in advance if this feels like a topic covered multiple times. I'm only asking because some of the old topics I found are missing images now. I'm in the process of getting a manual boost controller (BC). Nothing fancy, just getting a manual one for now as I don't plan to go crazy with it and would not go over 10 PSI. My car is not jacked up on boost steroids to do crazy numbers. I want to understand the OEM setup of the boost solenoid and vacuum lines on the R34 GTT so I know what needs to be changed when I do install the BC. I sketched the current setup to the best I could see and it's on the diagram attached. If the boost controller 'Wastegate Arrow' goes from nipple 1 to 2. My understanding is that the red vacuum line's "F" connector-end should be connected to BC nipple #2? Nipple #1 is meant to have the "pressure source" so what vacuum line would that be? Is it the green vacuum line?  From what I have read here, the OEM boost solenoid is not used at this point. So that can come out and then I can just plug the nipple that usually connects to the blue vacuum line?  So would the final setup look something like this?   Thanks in advance. I don't want to already be knee-deep into pulling out vacuum lines before understanding this. I'm a noob when it comes to boost setups so trying to learn as I go.
