Nice to know ill probably throw that in there when I need a new clutch. So far my stock clutch is holding great on 20psi. Once I get a new clutch BYT is gonna up the boost and make my tune more aggressive, but even on this conservative tune the car feels like a beast.

I have ordered my swap from zzp and had a question. As far as fuel considerations I was thinking about the BRFPS. But as I read through this thread I am not sure that is the best way. Do I need to do anything to the fuel system? And if so what would be the best route? I am getting the 252et and planning on 400.

My tuner has tuned both the s252et and the s256et. Told me the s256et pulls great in the top end and isn't that laggy and I should've gotten that turbo. I would've if I talked to him before I bought the kit but I was concerned with lag. But even on my very conservative tune and lower boost on my s252(I asked for it while I'm still on the stock clutch) it still has some big old *****, definitely happy with the s252et. Must be zzp's favorite turbo build for a reason, so their site says.

Anyone know more info on the hpt tuning tables involving the a/c and idle. my cars idle acts up sometimes when the a/c is running and I'm coming to a stop. my tuner said something along the lines that hpt didn't have a file or adjustment for this. Also do we have any MAF options over stock atm? I need to do something about my MAF as far as tuning for more boost. My tuner said I could run a 3.5inch tube as a probable solution to my MAF limitations. I wish he was here cus some of the stuff he knows is so far over my head and I'm sure he would be able to explain it better lol.

how built is your bottom end? if I were to go beyond 400whp which many will say the stock bottom end can take if tuned properly, then I'd build my motor to handle at least 500whp and go with the 256et. I'm runnin an ebay 60trim turbo and with a few more pounds and some fuel mods Im hopin to hit 400whp. Id go with the 256 but that is my preference.
