Since you decided to go with IAG, then you must pick a shop that is a IAG approved installer like Prime in NJ. That is how you get warranty on it. And BTW, Prime has one of the best tuners IMO. His name is JR and he tuned my first project car, great guy. People pay for his flights just so he can fly over to them and tune their cars, so yha.

Number 1: Just because you are a Subaru Shop that builds EJ eng blindfolded does not mean you are a IAG approved installer. I'm sure you have to get pre-certified by IAG themselves, have a account with them, and be their vendor. Number 2: One of the main reasons why people go with IAG is because of their warranty (Which I think is no better then what other shops offer, but that's my opinion). Just because they can build some solid blocks, does not mean there are no failure. Every shop has some block failure, no one is 100%. You do not need to push a eng to its limited for something to fail. There have been blocks fail with people just pulling in their drive way. Number 3: Not questioning your mechanical knowledge, but if you can build a EJ block blindfolded why are you spending the money on a already build block? It would be cheaper for you to buy a closed deck block, or send your used block to IAG or Outfront, have them Close deck it, and buy all the parts yourself, especially if you don't care about warranty. Just my friendly opinion, but opinions are like a$$holes, everyone's got one. In the end its your money. Good luck, if you want to chat or meet up, just PM me.

I've rebuilt plenty of EJ's and never a problem. For me to buy new case halves, crank, bearings, quality rods/pistons and have an open deck...for $4700 I get a clossed-deck and there high-end machining. Even of it were to spin a rod bearing for some crazy reason, I can easily rebuild it however I am willing to roll the dice |

Easy, building and blueprinting an ej is easy, but closed decking them is a lil harder diy

I think that's more of a big IF. GMs cars were factory certified to run on E. Federal testing and emissions standards exist for those vehicles. Different story with a Subaru, as no factory emissions data exists for alternative fuels on any Subaru. Don't get me wrong, I think being able to run E85 should be a loop-hole because of the environmental benefits, but it's not as simple as that. IMO if Cobb does manage to get any kind of flex setup certified, it's going to be severely neutered and not pro-tune-able. It would be similar to running flex on any other flex fuel car, which is not that exciting. I hope I'm wrong.
Sorry for the OT rant. |

Why the replacement stock size valves? Why replace them and why not larger while u are there.

If he wants to future proof the build sure, but it's going to cost a bit of driveability and shift the power to the right. |

Now if you have sponsors and a racing team where every HP counts, then yes I see a point there. But for a fun car, 5-10 extra HP is not a big deal for me. Last edited by BlackFighter; 03-22-2022 at 11:20 AM. |

Bigger valves were awesome the only time I have used them, but it was an 8v and was an upgraded casting at the same time

All of those plots were on the exact same built setup, we ONLY swapped out the turbo & up/down. With the smaller 3071 some WG duty cycle had to be added so spool up wasn't too aggressive. Most tuners feel that bringing torque on at any higher of a ramp rate than stock is just asking for a spun bearing. On the longevity end, if you stick with stock size valve (again with aftermarket valves) you have a much wider seat. Not only is this going to keep the valve round longer, and keep the seat in good condition longer. It will also pull more heat out of the valve with the larger valve/seat sealing surface. IMO, if you're building for streetability, then longevity trumps making a bit more power. If you have a racecar, then go for it. You'll be replacing engines anyway. |

I am going later this week to talk to my Tuner in -person and go over his ideas. IAG SB getting delivered tomorrow. I am going to "try" to do 93/Meth if possible though. I love E85 (run it in my GN) just a pita getting the Fuel. |

See what the Tuner says, I am fully aware E85 is King. 93/Meth is just easier so see what my options are |

Easier, until your failsafes fail and you blow an engine... which is MUCH easier to do with an EJ than with your GN.
I get it, I've been there. Truck shows up at my house with four 55-gallon drums of E85, and you're hand pumping gas into your car. Been here, done that. It sucks... but the power is so much better, and more importantly, it's safer power. I don't think anyone here is saying meth won't make power, it's just that E is such a better fuel if there's any way possible to make it happen. |
