I went for a forced performance red turbo from the states (stock position ) , great turbo and nearly half the price of most UK turbos , used there own 84mm intake pipe that matches the front housing of there turbos and this was a easy fit aswell to my surprise ,, it's made 531bhp @1.75bar so very happy with the results
As for the rotated set ups , iv had a 450 set up in both standard and rotated form , both none billet and the rotated was a far better setup, would spool better and also sounded loads better lol , but was also three times as much to buy , hence why I went standard position this time around Could you post more details about the turbo you went for please? Maybe a link to where you sourced it? Many thanks |

Hi Domino
Could you post more details about the turbo you went for please? Maybe a link to where you sourced it? Many thanks Here is there Subaru range of turbos , you need there inlet pipe aswell as they have there own size of inlet on the front housing but it seems to work very well http://www.forcedperformance.net/mer...Code=WRX-Turbo |

Only asking as seriously thinking of getting one Not really in a position to discuss numbers etc I'm afraid, take my advice and get one, that's coming from someone who already had a good turbo with the sc46 billet and replaced it with the precision |

Sorry for the late reply ,, it's a forced performance turbo , it's there none billet version of the red (one that's 750 dollars , you should see a review at the bottom from England , that's me aswell lol) , they now do a billet version aswell , they were very helpful in making sure I had all the right bits needed to fit the turbo and so far iv been very impressed with its results , and even had a comment from bob Rawle about how well it was working

Don't forget the slight chopping/grinding to the block and box housing to make it fit.

Yes I have, mapped by Martyn.

Ive also just bought this - to go onto my CDB 2.1 with 14mm stud conversion... Hope I can hit the magic 500 with Bob Rawle, yes I know BHP is nothing but a number, but it's the number I want to dick swing in the pub with haha

Possibly, depends how much boost you're able to hold up the top end.
|
You'll need some injectors but I'm guessing you just missed them of the list
|
You'll need 500 to compete with 450hp classics :)

Gotta agree with this. I've got just over 700 in my full weight Hawkeye and that runs a 10.9 on the quarter. That is identical to what my classic did which was 200hp less.
That was just as I turned up, no faffing with pressures, no launch control etc. A 10 should be easy in it when I do the tyres... |

You're making assumptions although my signature could be worded better . My 10.9 in the classic was done at circa 500bhp (flywheel). The car later made 601bhp flywheel again with a few changes but I never got to run it down the strip with that power.
The 10.9 in the Hawk was done at a tad over 600 wheel horse power so a tad over 700 at the flywheel. |
Ah ok.

Come on busta kid get with the programme lol
I take it you rebuilt the engine daz after it dropped a valve ? Ever get to the route of the problem? Car is awesome now your back in uk can't wait to see what your plans are Subscribed |
