Peoples thoughts of putting a full-race gt30r twin scroll kit on a stock v7 ej207, tune on e85? What injectors and fuel pump should I run? Any preferences on how to tune it? Or any other parts you guys would like to see me put on this set up. Thanks guys

You will need the utec so you can get speed density for that setup. Some of us where running GT30Rs 6 years ago on those motors. So search around.

Thanks Clark, I searched quite a bit so far. I sent you an email also. Do you think there's a better option for spool and horsepower wise then this set up? I'm looking for like 400whp on e85. Thanks for the help, I been reading as much as possible.

Aight guys. My timing belt skipped and blew my brand new engine. What timing belts you guys running? Any issues with skippage? I need to figure out the issue so I can avoid the problem.

My v8 was banged up a bit in transit and the timing belt was nicked. I replaced with a stock belt and haven't had any problems in the 15,000 miles since. |

Use a factory STI timing belt. Also make sure to adjust the timing belt guides and make sure they are in place. Its not a bad idea to buy the cosworth belt guide. Its $50 and makes sure the belt cant jump.

[quote=OppositeLock;31662603]The ringland is part of the piston. Its the groove machined into the cast or forged metal to hold the ring in place.
so your saying i would have to get a new piston? haha is there a place i can just buy one piston or would i have to get the whole set? |

You need a new short block or 4 new pistons, rings, and then have the short block rebuilt and honed.

A bit side tracked, but how similar are the parts (gaskets, belts etc) on the JDM compared to the USDM engines? I'm debating between a v7 and a USDM 2.5 for a track car project.. I just don't know if I want to get into a JDM engine/ECU and worry about parts down the road.
Lastly, what do you all you V7 owners do for your exhaust, would it be the same exhaust as the regular USDM wrx? Ryan Last edited by mcandrewsr; 08-23-2010 at 12:31 AM. |

Why do you think that happens - power drop-off above 7200 rpm? What is the bottle neck? P/s: Mine does it too. Cheers. Gerald. |

In which order would you prioritize that for a stock v8 EJ207 block? Also, is the stock exhaust manifold restrictive? Last edited by gling; 08-27-2010 at 03:59 PM. |

My V7 Spec C engine (out of limited with same engine code) is still out and can be upgraded. V8 Spec C cams? What about the intake manifold? Lay it on me with some suggestions! Going to use the stock turbo VF30 for now. Car will be a track/autox and not a dyno queen so looking for relevant upgrades. Thanks! I want to get the swap running smoothly before I do a significant power upgrade, but I have the engine out. Stuck between which I want to do. Decisions, Decisions... |
