Howdy

I have this boosting problem with my turbo setup on my 33. I have a high mount setup which i got from 2fast2furious...t70 with mani and a 38mm wastgate...yes i read all the shit about them from people and the cheap copies and blah blah blah...ive had no problems with it so far and its more for testing purposes in regards to a circuit car currently being built up.

The problem is when i have the avcr hooked up it doesnt control boost as i have set it. Eg...unhooked...it runs spring pressure of about 6-7 psi flat out...hooked up if i have it set to 14psi it will go as high as is possible throughout that rev range..highest so far is 1.85-1.9 bar or 26-28psi if thats what it is...its rather disturbing to see.

I have noticed on the solenoid unit that the third hole is open with no plug or screw in it to block it off. Does anyone know if this should be blocked?

My lines are setup with a t piece from piping after turbo one to bottom w/g and other to s/noid and one from s/noid (com) to top of w/g. Im fairly confident its correct. I currently drive around with the line from top of w/g unhooked from s/noid so it runs on spring pressure.

It's got me rattled for the last week. Any help would be appreciated greatly as i need to fix this before i can get it tuned.

    • I thought Australia got rid of the "drag dodgy fuel up to 91 RON with ethanol", which is why all E10 advertise as "up to 94 RON" ? Anyway I put E10/91 in the missus' Mazda because she empties the tank weekly, when all my cars get 98RON. tl;dr - turbo - 98 RON, if you can't afford that, sell it and get a commuter car (or tune your car for 91, which no one does).
    • Yeah i found that alot of parts can be wrong or "very" hard to get the real right one. I already bought some brakes years ago on me "old" GT calipers and they were wrong too 😄  I told them too. Even send them pictures...but they said "EBC catalogue has them on my car... So i dont know what their answer will be. I call monday them and let them know that they are really not on my car. If they were they would be already on a car...
    • Welcome to Skyline ownership. Yes, it is entirely possible parts websites get things wrong. There's a whole world of inaccuracies out there when it comes to R34 stuff (and probably 33 and 32). Lots of things that are 'just bolt on, entirely interchangable' aren't. Even between S1 and S2 R34's. Yes they have a GTT item supposedly being 296mm. This is incorrect. I would call whoever you got them from and return them and let them know the GTT actually uses 310mm rotors. Depending on where you got them from your experience and success will obviously vary.
    • Hi...a bit a "development" on the brakes. I spoke to the guys where i get brakes from...and they are saying that 296mm EBC are for R34 GT-T. I then went to their site: https://www.ebcbrakes.com/vehicle/uk-row/NISSAN/Skyline (R34)/ and search for my car(R34 GT 1998 - it has GTT brakes) and it show me this USR1229 number and they are rly 296mm rotors... So now iam rly confused... The rotors i have now on the car are 310mm asi shown... So where is the problem? Does the whole EBC got it wrong or my calipers are just...idk know what?  
    • Oh What the hell, I used to get a "are you sure you want to reply, this thread is XX months old" message. Maybe a software update remove that. My bad.
