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

    • If you take the top half of the intake off you can unbolt the flap off the shaft and leave the shaft in there blocking the hole. Then you can remove the little vacuum canister off from under the manifold and get a spare vacuum line to run to the ECU. I can take some photos of it later. Probably best to get the vacuum source to the ECU sorted first though. Mine all worked mint with the base map from the GTT an I've pretty much let the closed loop sort the fueling and took 1 degree out of the whole timing map.
    • This IS something you also have to configure in Haltech (or at least I did in the past when going from onboard-to-ECU map sensor and an external MAP sensor in haltech land).
    • I'm hoping it's something as simple as the ECU is looking for an external MAP sensor, but he is trying to use the onboard MAP sensor.
    • You won't need to do that if your happy to learn to tune it yourself. You 100% do not need to do that. It is not part of the learning process. It's not like driving on track and 'finding the limit by stepping over the limit'. You should not ever accidently blow up an engine and you should have setup the ECU's engine protection to save you from yourself while you are learning anyway. Plenty of us have tuned their own cars, myself included. We still come here for advice/guidance/new ideas etc.  What have you been doing so far to learn how to tune?
    • Put the ECU's MAP line in your mouth. Blow as hard as you can. You should be able to see about 10 kPa, maybe 15 kPa positive pressure. Suck on it. You should be able to generate a decent vacuum to about the same level also. Note that this is only ~2 psi either way. If the MAP is reading -5 psi all the time, ignition on, engine running or not, driving around or not, then it is severely f**ked. Also, you SHOULD NOT BE DRIVING IT WITHOUT A LOAD REFERENCE. You will break the engine. Badly.
