Build Updates:
Well, things are changing fairly substantially and I think for the better. Instead of the 2.5 +4mm 75mm stroke longrod we are going to go with a 2.6 +2mm 79mm stroke revving to 8800ish instead of 10k. So we will get a bit better spool out of it and things are matched a bit better so the powerband should be the same or better. 10k rpm would have sounded amazing but oiling on long pulls, plus the custom cams I would have had to get to make it make sense to rev there aren't worth it for a car that will be street driven (not daily driven, just will see street time and cruises). Not to mention I was already over-geared anyway with that much RPM. I also already ordered the Cosworth 79mm billet crank. I know a lot of people have said the stock ones are adequate, but the oiling looks drastically better on the billet options and the car will spend a lot of time over 8k rpm, not just short bursts during mile runs. Apparently we are now just waiting on the new crank and pistons to show up. Edit: Also forgot to mention we are going to target 9.4-9.5:1 compression ratio.

Surprised you didn't do 10:1 since ull be running e90+
Good to see things changing I'm looking to that build also! It's joe btw lol. Still am considering a eg33 to make over 800 myself. I just want it to be reliable. |

6 cylinders vs 4. 50% less the effort it has to be more reliable.

All of the shops I have been at, would have covered this on their dime with out a doubt. This comes down to a builder or assembler who did not check the parts they were using and it came back, assuming it is not melted bearing material in the passage. Most of these passages are drilled from one side, not from both. So it is odd that the passage has a blockage midway, yet being to size(assumed) on both journals(entrance and exit). A good cleaning and inspection of the bottom of the hole(middle of the passage at the blockage) would reveal if it was mis-aligned(drilled from both sides), transfered bearing material. It isn't always about poor quality control either. It has more to do with statistics. Make enough parts long enough, some one is going to mis something at some point regardless of your quality control practices. It is an unavoidable fact of manufacturing. |

Sorry for the loss and looking forward to the new beast in the making! Unfortunately, many of us here in the built engine world have felt your pain at one time or another. It is a labor of love that is for sure!
+1 for MPS. They are dedicated to making each and every person who comes through their doors happy (and fast) when they leave. Dom spent many late nights on my build and I feel very lucky to have a shop like that in my backyard. Hoping you make it to 4 digits and post lots of videos for us mere mortals hahahaha |

I think anyone with some real passion could have very easily lost there heart for modifications due to some crack in integrity from that situation. I'm glad you stayed in it though, it was great talking to you the other day. Remember, fluid dynamics are your friend, you just need to make them do what YOU want. Build your walls and create your veins my friend. -Mark |

I'm liking the idea of a +2 2.6 more and more.
I just wish it could rev safely to 9k and that's it. |

Have the triple plate en route I was talking about before so the 6 puck won't matter anymore from a previous conversation in this thread. |

I still don't understand the obsession with high reving motors...
EVOs have 2.0L that can rev to the moon.... and most of them are switching to 2.3L and 2.4L with similar rev limit as our motors.... and we are going the other way |

Part of it is gearing. I would rather keep a smaller diameter tire and keep my gearing shorter (final drive number higher) to keep up acceleration if I can hold power higher in the RPM band. I might end up going to a taller tire regardless depending on how things turn out. It wouldn't be such a big deal if I could just swap out a ring & pinion in a rear diff to impact gearing. Part two is powerband. I am not committed to this being the last turbo on the car, the larger the turbo the longer it will take to spool and I would like it to at least have enough room in gear to be usable off spray. Part three is stroke. We can't fit as much of it without running out of block height/rod ratio. Even the 83mm crank gives the piston wiggle room at bottom dead center. We have to look elsewhere. The other, less substantial, part is audio orgasm. But I guess that is personal preference. |
