I would try giving PDXtuning a call. I think they sell axis stuff and gt35r kits.. I'm sure there are other shops to talk to too but they are local for me and they are really cool about answering any of my questions.

The block wouldn't really make much of a difference. The brand gt35r kit, AR of the turbine housing, and octane gas used would though.

I have ordered the perrin GT35R turbo kit with .82 a/r.
Will be ranning pump gas 100ron and maybe race gas c16. Just like to know if the axis racing stagelll block is up to task to handle some series boost. Looking to achieve at least 400+whp. Im currently in process of stripping my MY02 WRX motor down Im not sure weather the std heads and cams would do the task Thanks ken |

WRX heads work to flow better along with valvetrain and cams would work fine. I wouldn't-not-work the wrx heads though. They seem to be fairly restrictive at the power levels your shooting for.
Do it once, do it right |

My ****ty conservative tuning : 319.5 whp on Indonesian pump gas (maybe equal to US 91-92 octane) with catless 2.5' exhaust piping. Temp: 33C (about 92F) Humidity: 64% Ramp rate: 6 As result comparison: - Stock EVO 8 got 205 whp with pump gas mix with AVGAS on that Dyno. (AVGAS octane rating is about 115). - EVO MR with Motec, Jun 272 cams, Injector, FMIC and so on but still using stock turbo .. got 260 whp on pump gas tune by profesional. I am using WRX head and Jun Cam. Now my car still tuning by profesional. Will dyno again soon .. Last edited by WRX-Blue-Mica; 02-02-2006 at 11:05 PM. |

WRX-Blue-Mica,
so ur ranning 1.6-1.7 bar of boost fr FP green and only getting 319.5whp. that sounds to me that there might be some restriction some where coz 1.6-1.7 bar of boost is hell of boost. any chance u can post ur dyno graph or send them ? thanks ken |

If it is close to the dyno dynamics we use in the States (which I would expect to be) stock STi made 219whp. (mine with 3k miles on the Vishnu dyno dynamics dynometer).

there was a spreadsheet that Vishnu had put together that gave a general idea of the whp between different dynos. But IMHO it is not worth the effort to translate. Even same brand dynos in different locations produce different results. My gut feeling is if one can do a before run and an after mods run the difference would be more meaningfull. Also if the car feels great and one is happy with its performance then it can be ok.

Vehicle:RIP I'll always be The Ver8 Magistrate |
The 2.35 is my favorite motor. The best built motor I ever saw was the Axis 2.35. Felt like an OEM motor only stupid powerfull. It did use JDM ver8 heads and stock gaskets by the way. I have seen other 2.35's as well but none ever came close to this Axis motor. Another mega buck 2.35 built by another vendor who frequents the boards was put into a car and the car was sold twice in 3 months because the motor was just a problem child. The clanking and slapping was like a deisel motor. The third owner got it to make respectable power but with all that piston slap it will go one day I wager.
Built motors are risky and not for those who expect it to drop in and work right off the bat. It can mind you but man some swaps go on for months and months and months and if it does have a problem before it gets out the gate and it gets warranted by the builder then it takes another 6 months to get another and you cross your fingers again. Every car I know of that has been down for 3 to 9 months has been due to built motor swap. Even regular OEM swaps can be problematic but built units, yeesh. I know of right know that is burning a quart of oil every time it runs and it has never even been tuned. Put in and burns oil. It is the second one too and been going on for 8 months now as in the car down for 8 months. Now there is dispute from the builders, yada yada yada, same story, happens all the time. Me, I would shy away from them but if you brave the waters, good luck because when they do work, and some definitly do work well right out of the gate, like that Axis 2.35 did then it is magic man. Good luck! |
