should have no problems if you run a tunable ECU, new injectors , dyno time and move the AFM..... i'd say 4000-4500 rpm for full boost with the larger exhaust...

do it right rather than just bolting on a big turbo as you will more than likely lean out the engine then you are looking for a new one.

maybe add some heat sheild under the bonnet above the turbo as your bonnet is going to get very hot.. HEHEHEH looking good though

Got any specs for it? Exhaust A/R? What model T04 is it? T04E? looks to be an older style garrett turbo, looking at the compressor outlet.

Anyways, Going by looking at it....... and Judging by the T4 footprint and the size of the comp cover/exhaust housing, That thing is going to be a lag monster, as that is a VERY large exhaust housing for a little 2 ltr.

Ive just purchased a Trust TD06 20G 8cm, and I thought that would be a tad laggy, but from everything I can read Im looking at maybe 4000 - 4200 full boost. And that's a shitload larger than a TD06 mate.

If your car is "Drift style", why go for such a large huffer? Why not go for something really responsive with good power delivery? Is it A genuine garrett or an ebay job? The manifold sure looks EBAY spec. And why mount the AFM directly on the front of the turbo?

If you want to retain some form of street drivability, then I suggest maybe a smaller turbo. Or at least a smaller exhaust housing. Id be very surprised if that made full boost before 5000-5500.

Mind you, this is just by a visual inspection. Id be after some more data to give more confident advice.

What other mods are done? Injectors/Cams/AFM/management/internals.... cause you'll need the first four if you intend on running some big boost with that thing.
