e85, green, stock block, safe?
i am running fp green on stock block with supporting mods, only engine mod is headstuds. im thinking about opening up the turbo and raising boost with e85. i was just wondering if the stock motor can handle 25-28psi?

This had been done numerous times on Evos!! You should be fine. {thumbup}:beer::mitsu:

Yea, you have headstuds. Should be fine.
|
Are headstuds even needed for that power requirement?
I would assume you would be fine as long as you have the supporting fuel mods and tuning. |

It is better to be on the safe side rather than the other way around.

Diiirk had a Green with supporting mods on e85 for a while and ran 10.72 @ 127. I don't think he has head studs. Well at least his mod list doesn't say so. From my experience as a technician for 5 years and based on what I've read, for the power you'll be making with a green and e85 I really don't think head studs are a necessity. On top of that, not having them is like a fail safe. If you have head studs and for whatever reason you start to have pre detonation, whats going to happen when a piston starts to compress air and fuel thats burning and expanding in the combustion chamber? You'll be producing some serious heat and you're going to bend a rod or bust a hole in the side of your block. On the other hand with the factory head bolts in the same scenario, they'll stretch, you'll lift the head and all you'll have to do is replace a head gasket and clean up a small mess. I honestly can't justify doing head studs unless you plan on producing upwards of 28psi on a turbo at least the size of a red or unless you have the head off already and its just plain convienient to do them. If it ain't broke, why mess with it?

-Shane to my knowledge 4G's arent really in need of headstuds for the little HP a Green is gonna make. You can push it hard and make more HP, but again, I just dont think its needed on this motor. If I had a reason to take the head off, then id prob do a set to have em though. |

it's all in the tune. i can't emphasize this enough.

I had no issues with my Green on E85 and a stock bottom end at 31psi.

Needed? Maybe not. Safety precaution though. The way you learn that you needed them is when your headgasket goes or worse...

IMO, you should get headstuds they are only 200 or so not sure, it's a way to stay on the safe side , arp headstuds is one of the first mods i ever didi to my car , and they will aslo prevent lifting your head.
