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.

      Car Rotisserie

      By Shoota_77 · Posted

      Hi guys, has anyone either purchased or built themselves a rotisserie for their car before? I can only just justify the need for one hence why I should just make one but at the same time, if I make one I can kiss another 4 weeks of potentially productive car working time goodbye because I'm building a bloody rotisserie....  I mainly want it for the application of the body deadener.  Cleaning the old stuff off, priming and then colour over the deadener doesn't worry me, it's just the application using the Schutz Gun that I feel would achieve a significantly better finish painting it side on and keeping the Schutz Gun upright.  I don't think they would work well on the side let alone almost upside down for some areas.  If the product I use (Terosun, etc) could work through a HVLP ok then it might be ok to apply without the rotisserie.   I can get one of these style ones for about $1200 which is pretty good value-     I reckon if I made one it would cost around $500 but it's more the time that it would take is more of a killer than the cost.  They look to hold their value pretty well second hand so I could always sell it after using it and realistically only lose $200-$300 at worst.  Or keep it and buy another project when this one finally sees the light of day... Anyone selling one...? Cheers!

      Stock rb25det neo questions

      By GTSBoy · Posted

      While it is a very nice idea to put card style AFMs into the charge pipe (post intercooler, obviously), the position of the AFM and the recirc valve relative to each other starts to become something that you really have to consider. The situation: The stock AFM is located upstream the turbo, and the recirc valve return is located between the AFM and the turbo inlet, aimed at the turbo inlet, so that it flows away from and not through the AFM. Thus, once metered air is not metered again, neither flowing forwards, or backwards, when vented out of the charge pipe. When you put the AFM between the turbo outlet and the TB, there is a volume of pressurised charge pipe upstream of the AFM and there is a volume of pressurised pipe downstream of the AFM. When the recirc valve opens and vents the charge pipe, air is going to flow from both ends of the charge pipe towards the recirc valve. If the recirc valve is in the stock location, then the section between it and the TB doesn't really matter here - you're not going to try to put the AFM in that piece of pipe. But the AFM will likely be somewhere between the intercooler and the recirc valve, So the entire charge pipe volume from that position (upstream of the AFM, back through the intercooler, to the turbo outlet) is going to flow through the AFM, get registered as combustion air, cause the ECU to fuel for it, but get dumped out of the recirc valve and you will end up with a typical BOV related rich spike. So ideally you want to put the AFM as close to the TB as possible (so, just upstream of the crossover pipe, assuming that the stock crossover is still in use, or, just before the TB if an FFP is being used) and locate the recirc valve at the turbo outlet. Recirc valve at the turbo outlet is the new normal for things like EFRs anyway. In the even of a recirc valve opening dumping all the air in the charge pipe, pretty much all of it is going to go backwards, from the TB to the recirc valve near the turbo outlet. But only a small portion of it (that between the TB and the AFM) will pass through the AFM, and it will pass through going backwards. The card style AFMs are somewhat more immune to reading flow that passes through them in reverse than older AFMs are, so you should absolutely minimise the rich pulse behaviour associated with the unavoidable outcome of having both a recirc valve and an AFM in the charge pipe.

      Yep, in my case as soon as I started hearing weird noises I backed off the tension until it sounded normal again. Delicate balance between enough tension to avoid that cold start slip and too much damaging things.

      I'm almost at a point where I feel like changing the alternator. Need to check the stuff you mentioned first though.
