hah funny, dont think im a newb, i forgot my password on my other account. the turbo isnt really the problem. its just what exact parts. I dont want to go full race block, but really reliable if im planning on getting 400+whp. I have talked to a couple shops. and all said thats it up to me. didnt make since to me neither

if your hp goal is 400whp,
just pick between GT30R or GT35R in 0.82 trim - easy as that of course you'll need the supporting mods 800cc - 1000cc inj dual Walbros or Bosch 044 etc.... |

A set of pistons will make it reliable.

I'd consider rods as well. Forged rods are pretty cheap insurance in my opinion considering if they go you've pretty much trashed a block. And I have seen 2 blocks with a blown rod, 1 was un-salvageable, and the other need around $2k in machine work/parts to run again.

While you are in there , I would pick up some good bearings. I have seen some forged blocks fail , and everything looked great...except a bearing.

true that...so pistons, rods, bearings and arp headstuds for a bit more insurance as it is easy to turn up the boost on race gas but not so easy to put a headgasket back together

Go to the race shops near you and talk to them. Those guys blow up motors for fun and R&D. THEY know what will handle how much/when/where/why. You shouldn't ask the 16yr olds on here......Daddy is still paying for everything. (Well, with the exception of Micah....dear lord I look forward to pics.....and your destruction pics too!!!! ) |

now I dumped the billet crank to find where the new subaru oem crank will die (for oiling system ****s and giggles)...and that will be my excuse to run back through the block and o-ring before running the 4202R and 6-spd dogbox |

What would I do? Eactly what I just did!
USDM EJ257 block. Sleeved with heavy collar top sleeves and finished to suit 100mm bore. CP pistons 8.5-1 comp coated skirts. Altered compression height so I can use long rods New EJ25 crankshaft with extra oil holes. Argo billet rods (as your in the US use the Pauters) ACL race series bearings 12mm JDM oil pump Block has ported internal oil passages. Custon large capacity oil pan to eliminate chance of oil aeration Thats what I curently have in the garage, just in the process of starting to blueprint, final machining and assembly.
