Only the hybrids fit the stock turbo mani. Tough they seem expensive, they're a a simple bolt on. Keep in mind there are other mods involved too. What are you're current mods and hp goals? Even with the stock turbo, a 3" exhaust and a couple other mods will get you 220-230 whp.

To answer that one, I suggest you spend some time reading in the 2nd gen section. Brian has 4 stages of his turbos. I believe I read somewhere that someone hit near 400 hp. That's not a number I would strive for on a turbo based off of the HT-18. Going for those numbers I would prefer to use an aftermarket turbo, manifold and bov.

you're going to have fun fitting anything with the stock manifold. It's not a chassis issue, it's an intake mani issue. the stock manifold puts it very close.

on the contrary, with a good aftermarket manifold there is little you can't fit. I have a manifold that swoops forward, putting the coldside about even with the waterpump, and I'm running a t04e 60 trim, .96 a/r hotside with LOADS of room around the turbo, on all sides.

and by t04, I assume you mean, t4,which will not fit on a stock manifold, they are t3 flange. there are adapters however due to the intake spacing I'm not confident how that will all fit.

and and and, I got my turbo with manifold for under 400 bucks, then got a 50mm wastegate for around 250, some people spend more on the bnr itself. it's all in how you shop.

**edit** and that's not ebay stuff. it's a custom stainless manifold, HKS gate, and garrett/airresearch turbo. BUY USED

I have a BNR stage 2 turbo. A series 5 turbo was used for this upgrade. I'm using it on my series 4 motor. I can tell you that it does sit very close to the intake. Infact. I could not mount it initially because the "nubs"/or whatever you call those pieces that the bolts that hold the turbo together go into were hitting the intake manifold. I had to grind one or two of them down as well as slightly clock the turbo to make it fit properly. (I'm not sure if I would have had better clearance using the series 4 turbo).

I can't tell you what kinda power I'm making yet as I'm still breaking in the motor and I need to get the microtech tuned before I push it. I might have pics of how the turbo sits on the motor if your interested.
