Not really. All 3 have the same size comp covers. They are interested moreso in response difference between -5's and the GTX2863 to confirm the 'on-paper' results with real world results.

The fitting of them to the car is probably going to be the most difficult thing. They run the disco comp cover which is larger than the -5/-7/-9 comp cover so we don't even know if they are going to fit in place.

We would prefer to have them tested locally for fitment but power figures from anywhere (except WA) will be ok

Anyone know how necessary it is to run the GTX front comp covers on a 2863??? Would machined -5 comp covers be ok so I can keep standard piping???

I went down and asked GCG myself. They reckon it just won't work with these wheels but who knows? It's a lot of money and effort to throw in the bin if it's a flop.

Daz, put a pair on and use a MAP sensor ECU.

Do all the piping up (I've spoken to Jack about this BTW), then do a power run. Now, take the piping off and run just the new comp covers open to the air unfiltered and with zero additions to the comp covers. Another power run. See what happens - thats the only way to know for sure and yeah, isn't exactly a cheap thing to do

Edit; That may not make sense. Sorry, the only way to know for sure is to try some back to back, one set with the stock GTR size covers and the other set exactly as Garrett designed them :)

Ive said this in the GTX thread yet I have already made the 'for science' call to GCG about ditching the fancy comp cover. Unfortunately the answer was that being a 'full blade wheel' they actually need a specially done surge slot for them to work. Results would be bad they rekon if you tried without the slot.

I made this call as at the time I had a disco, and wanted to know if they could simply GTX my disco (essentially the same outcome bar the comp cover) so yeah.

Gcg or any turbo company, should b looking at how to adapt the factory housing on the gtx series as they would make a truck load of cash, basically bringing out a hole new line up for gtr low mounts around the world.... Not everyone what's a big dirty cheater single.....

Yeah but for one model of engine? That really wont be more than 1% of sales for the $$$ in development... As it'd need more than just adapting a housing (aka buchtered GT3076s into RB25 housings that don't work... or AVO/Sonic housings)

Like Shell V-Power racing, just not viable from a business model.

And realistically if you are chasing 500rwkw+ which they provide - you are hardly looking at bolt-on approaches or setups.

    • Hi, i’m making a rb25det coil loom for Vag short coil. Can anybody tell me which Ecu signal wire belong to coil number 1 and 2,3,4,5,6? The connecting switch in above pic is 8 wire i think white is for +12v and black for earth.
    • Was there ever a model of the Stagea m35 that didnt have a badge on the grill? I thought I saw that somewhere, some aero edition or something? I cant find it again? davemoto
    • Its a 2002 vr-x four VQ25DET, silver. Coil overs, lowered, polished alloys and sport exhaust. Bit of a project, was sitting in a shed for a while but runs and drives great.
    • I wasn’t able to replicate the sound anymore. It was a one time sound so maybe it was just coincidence but it was like small pebbles being dropped in a coke can.   should I try cleaning the MAF? It could be it’s functioning but dirty? I don’t know.
    • Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.
