Only if you want laaaag, dont they use a 3076 chra? Way too big for the stock housings unless you are shooting for 300kw on 98. I would suggest staying as close to stock sized wheels as possible or you will have to factor in thousands in ecu, engine and gearbox mods.

yeah sorry i should have mentioned that

engine mods? nah. gearbox mods? shift kit SHOULD do it. however i notice the US guys are using new TCs to stop overheating. However this is before they do shift kits.

ECU is a necessity anyway, even if its to trim fuel on a stock setup

unless you have some way of controlling everything don't go bigger than a Sierra Stage 1. This is a proven good setup with the VQ25DET.....if you go bigger you WILL have lag issues.

I have the GT30/71 core with the Garrett BB set but I have spent a lot of time and money getting it sorted......only go this way if you find some way of controlling/modifing the Cams and Throttle restriction!

My suggestion is to go with Precision Turbo's in Wetherill Park.....while GCG are OK they have a very noisy barring......to me they don't sound right.

Cool, appreciate your feedback on GCG, i think I'll avoid them.

I'll do some more research and also give Precision a call when the time comes.

Turbo arrived today too, thanks Griffin!

Sold to me!

I ended up paying $100 for it, not sure if that's good or bad but to me it's a great insurance policy to have hi-flowed and ready to go in when the original one packs it in.

Um, no. Back one page you'll see it's sold (to me). thumbsup.gif

Cheers,

Jas

    • AHHHH gotchaa, I'll do that once I am home again. I tried doing the harness with the multimeter but it seems the car needed a jump, there was no power when it was in the "ON" position. Not sure if I should use car battery jump starter or if its because the stuff that has been disconnect the car just does send power.
    • As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.  
    • It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack. 
    • Probably not. A workshop grade scantool is my go to for proper Consult interrogation. Any workshop grade tool should do it. Just go to a workshop.
    • In my head it does make sense to be a fuel problem since that is what I touched when cleaning the system. When I was testing with the fuel pressure gauge, the pressure was constantly 2.5 bar with the FPR vacuum removed. When stalling, the pressure was going up to 3.0 bar (which is how it should be on ignition).
