Ok so i took the car for a run yesterday and thought it was off the show (not able to keep it straight and just lighting up the rears) anyway i dont have my boost gauge yet and wasn't 100% sure what it was running. Figured it to be around 12 -14psi so i borrowed Griffo's boost gauge and "BOY" was i off. :innocent:

The little old RB20 was boosting at slightly over 1.5 bar. :chairshot

So we turned the boost back to 1bar and is MUCH better, still very easy to loose the rear end from time to time, just have to moderate it with the right foot. :confused:

Im going for 240rwk's once i get the FMIC on an exhaust but i think TimmyB can back me up on this as i think i have one of the toughest sounding cars getting around on Tassie roads :Pimp2:

Pics to come guys.

Sorry guys was in a bit of a rush when i posted this yesterday. Realised i had posted it in the wrong section and then reposted it in here. Just realised though that i cut over half the original post off.

Hope this helps to clear it up a little now.

Car mods as follows:

TD-06 turbo with external waste gate (50MM i believe)

bigger injectors (with extra injector for high boost)

GReddy injector equaliser control (is what i've been told it is)

aftermarket ECU

electronic boost controller

upgraded fuel pump and swirl pot

adjustable fuel regulator

Z32 AFM

GReddy BOV (currently venting to atmosphere

GTR intercooler (replacing stock intercooler) want a FMIC

3' dump from the turbo into rear muffler which is standard at the moment, with extractors.

GTR rotors and calipers (is what i've been told)

irridium plugs and upgraded ignition coils

rods and pistons have been done as well as bearings (is what i was told)

set of race springs and HKS front and rear strut brace.

Apexi air intake with modded CAI /Heat shielding (thanks to SAU thread)

button racing clutch and locked diff (want to change diff)

Have not dyno'd the car yet as im still getting it on the road and everything sorted out. When i do i'll let you know how it goes.

Talking to the tuner yesterday and he said if didn't have a couple of hundred kilowats after driving it he said he would eat his hat

Can not wait to get it on the road although i have been re thinking it as a daily driver now!!!

That's a nice looken Gts-t. that's a sweet colour, is it factory?

Cheers dude. I love the colour as well thats what first attracted (can i say that about a car :confused: ) me to the car.

As far as i know its not a stock colour. It was resprayed in Japan. You should see it in person its looks even better.

Haven't had time to give it a wash and polish. But will give it a full detail when time permits then post some more pics. :Pimp2:

on the boost thing, it could possibly be the diaphram in the wastegate is faulty??? that caused a mate of mines rotor to eventually see his boost guage off the scale and pop the motor

Nah its cool man its all sorted now.

Borrowed riffo's gauge and we went for a run, realising that it was just over 1.5 bar set off the EBC. Has now been turned WAY back and all good.

BUGGER for your mate, not good at all.

ah good... yeh it was a 30psi boost gauge and it was reading like 40 or more, checked it again to see if the guage was faulty and yeh not cool killed the turbo and motor.

BUGGER, not good at all mate. Thats why i borrowed Griffo's gauge to see what was going on. EXTREMLY GLAD i did now :rant:

The general feedback i been getting about the car has been awesome. Everyone loves the way it sounds, got to love a screamer :Pimp2:

      S1 headlights?

      By Duncan · Posted

      It might be worth having a good look at the chassis behind the bumper then; most people prefer the series 2 look so it might have been changed to cheaper parts as part of an earlier repair

      By Celticsfan03 · Posted

      The car itself a series 2. I was just curious about the headlights and just wanted to confirm that they were series 1. Good to know the rest of the front end is series 1. It’ll be easier for me to find parts on the aftermarket side of things lol

      R34 engine swap Rb25de neo to s1 Rb25det

      By WMDC35 · Posted

      If you've wired up the coils & injectors properly, & have the neo CAS loom for the trigger, it should all work. The VCT works the same way so just different plugs between s1 & neo. Assuming DBW if no IAC. Don't bother with the stock boost solenoid with g4x.

      THERE IS NO IAT SENSOR ON ANY SINGLE TURBO RB. And the one on an RB26 is not for "engine control" - it's really too big and too slow and is only used for over-temp alarming (as far as I can tell). Anyway, you don't have one. You want/need one for the Link, then you need to buy one, find a spot for it, and wire it in. You do know that the stock boost solenoid is not capable of "control", right? It is merely on or off, for the low boost (5 psi) and high boost (7psi), which the ECU enforces mostly based on gear. The stock solenoid is not for PWM control and is not plumbed up in a way to provide it. If you want to control boost properly, then you need a proper MAC valve. And yes, you can wire either of them direct to the ECU. Well, I assume you can - I don't know what the boost solenoid pins on the plug and play Link are capable of. They really should be as capable as any normal Link - but seeing as it is plg and play, it might be limited to stock functionality. Read the doco.   You really do just want to plug stuff together without understanding how it works, right? I can't help you there. I don't know the plug types or pinning on half the stuff you're asking about. If I had to do it I would sit down with the wiring diagrams, the car/looms and a multimeter and work out what is what.

      Factory oil temp sensor in a RS4V without gauges?

      By GTSBoy · Posted

      Light should be a pressure switch, not a sensor.
