This custom job is by machine shop all in pr call this (pineo) it like another 2 bolt in the engine. That engine modification help to be more strong.
86-95 Rx7 13B 2mm No Recess Solid Corner Seal... I'm just parroting info I heard from an engine builder in the UK about those soilid corner seals with a reccess ... apparently they have had lots of side plate failure issues when using them. Interested to see what that 2 bolt modification is . Any pics ? I had mine doewlled which seems to do the trick . |

But it's like anything, any mistake can damage the engine. We still have two options goopy apex seal 2mm RENESIS or 2mm oldschool. We still need to find a machine shop to install correctly 2mm oldschool. |

video soon. so you can see well the modification.

Now running rx7 depth 2mm . I understand that you just need the extra bolt and corner seal solid. |
Mine is running in the 400whp+ region currently .... my engine has rx7 apexs, dowels, and modified corner seal plugs ( using rx8 parts).
I'm in NZ but we can talk on google hangouts (brettus8@gmail.com) if you like . |

Many temperature inside the engine is equal to break.RENESIS engiene is high compression. In high boost you can not go very high in timing. For this reason large turbos are used to avoid taking hp by timing. |

Some exhaust porting work , a unique siamese wastegate setup , large (gt3582) turbo with 1.01AR twin scroll turbine hsg. Free flow 3" exhaust. And w/m injection. So yes much thought was given to maximising exhaust evacuation and 400whp is now easy to achieve at fairly low boost. |

This is important to lower temperature in our engine. I understand that the extra bolt and solid corner will help a lot to your setup. In addition I will modify some air inlet chamber. Looking for the engine last longer |

looking forward to results. Specs remind me of the T04z which always made good power on rx7s. I wonder if there is any new tech in the wheel designs to promote better spool and power

Well, it's running I guess.
|
Yes. Running like factory but need tuning on boost.

You should make up a scoop off the fans to force feed air off the rad. fans into the turbo inlet . Would work better than just blowing hot air all over the turbo......:suspect:
