I have just picked up a GT-RS and have noticed that unlike the standard turbo, the exhaust outlet and the wastgate outlet are seperated.

I currently have one of the BOS/Batmbl split/dump pipes, and these are obviously going to jag on each other in this area.

My questions are, if I cut the seperator off on the split/dump will this be fine or will the wastgate flap hit the dump pipe and not open properly??

Should I go for another dump pipe? and what suggestions are there?? I dont really want to buy a massively expensive one, so would a bell mouth be the cheapest and better option?

Cheers

I tend to think that a GTRS being a bolt on turbo would suit the std outlet pipe and anything of the same nature .

What you can do is take your GTRS with you when you go looking for dump pipes , pop the actuator arm off the waste gate arm and trial fit the dumps and manually open the gate via its short arm . You may even take a few clean nuts and bolts to hold the two together while you open the flap valve . Should be very easy to tell if the flap fouls on anything .

One handy tip , if you can bolt whatever dump you end up with to the turbo before you fit it because they can be a pain to do in situ .

This is why I prefer seperate dumps that place the first joint down where it's easier to get at the fasteners .

Thing is I'm in TAS, so anything I get will have to be ordered and paid for before I see it.

Who has one, and what are you using?? Standard dump pipe is out of the question.

I think I'll just get a JJR Bell Mouth.

    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
