Link G4X ECU R33 GTS-T

[thkyline]

So, its been about a year since i bought it and i was thinking about getting a new ECU for the car i figured that there's too many restrictions to the old one unless you get a Nistune but i didn't really trust the Nistune to keep a 30yr old engine from detonating (i could be wrong but i was also trying to justify getting the Link).

its running a factory auto box so there's not a whole lot you can do to it other than running a piggy-back type set up, i had my eyes set on a link G4X but i didn't want to waste the potential of such a good ECU on a piggy back especially if it still has to run the stock Mass Air Flow Sensor.

After a fair bit of research and contemplating getting a turbo 400 box or even an 8hp zf box i went the cheaper option and put in a full manual valve body figuring i could get the stand alone G4X to work with this.

Stock MAFS was the first thing to be cored out, new XSpurt 1000cc Injectors Installed with an Aeroflow Fuel Pressure Regulator, Manual valve body installed, New 3076 turbo installed, De-cat and a few other bits and pieces.

Sure enough the stand alone Link G4X worked really well with all of the mods. The skyline runs so smooth and it definitely gets up to boogie when it needs to, such a fun car to drive now with no flat spots and what i think is a near perfect tune.

its running about 19psi boost but i might increase to 21psi down the line when i get the intercooler pipes welded as it keeps blowing off the silicone hose connectors.

...and a wrap over the old flaky paint because i couldn't be bothered doing a full respray just yet

With the cooler pipes, does they have a lip around the end of each pipe, and what type of clamp are you using. I use good quality boring old hose clamps one mine at 20ish psi and they hold OK.

Just the cheapy ones from autobarn, the original pipes have the lip on them but the other ones that dont have the lip are where the issue is with them blowing off, to be fair its probably from not tightening them too much because i dont want to strip the threads which i've done a few times already.

which brand do you use? also, ive been told that ive theres too many tight bend in the pipes it can create turbulence so i sort of wanted to get a nice even curve to all the lines. whats your thoughts?

[Duncan]

Yeah so you can just the bead added to them by anyone who has a bead roller, I'm sure that will sort the issue.

I have a mix of wurth and tridon hose clamps on mine and run 24psi no problems.

ah yeah, that makes sense and sounds a bit cheaper too. ill have a look in to it, thanks heaps!
